| 3 | maint: re-anchor all .gitignore entries. |
| 4 | * bootstrap: Copy from gnulib's latest for the fix to |
| 5 | automatically anchor entries it constructs. |
| 6 | * gnulib: Update to latest just so it has the same bootstrap. |
| 7 | * .gitignore, build-aux/.gitignore, doc/.gitignore: |
| 8 | * lib/.gitignore, m4/.gitignore, po/.gitignore: |
| 9 | * runtime-po/.gitignore: Re-anchor all entries. |

| 12 | |
| 13 | Fix portability problem on OpenBSD 4.7. |
| 14 | |
| 15 | Jim Meyering reported this in |
| 16 | <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>. |
| 17 | * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h, |
| 18 | not _STDLIB_H. EXIT_SUCCESS has been defined by the standard |
| 19 | for quite some time. |
| 20 | * src/parse-gram.c, src/parse-gram.h: Regenerate. |
| 21 | * tests/regression.at: Tamper with the renamed witness. |
| 22 | |
| 23 | Adjust to recent changes to gnulib bootstrap. |
| 24 | |
| 25 | * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore: |
| 26 | * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore: |
| 27 | * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore: |
| 28 | * tests/.cvsignore: Remove; I don't use CVS to maintain Bison |
| 29 | anymore and don't know of anybody else who does. If someone needs |
| 30 | these files, they can resurrect them. |
| 31 | * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore: |
| 32 | * m4/.gitignore, po/.gitignore, runtime-po/.gitignore: |
| 33 | Omit leading '/', since bootstrap omits it. |
| 34 | Adjust file names to match current contents better. |
| 35 | * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook |
| 36 | installed just for us. |
| 37 | * bootstrap.conf (excluded_files): Don't exclude codeset.m4, |
| 38 | glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now |
| 39 | needed somehow. Don't have time to look into why. |
| 40 | (gnulib_modules): Change malloc to malloc-gnu. Do we really assume |
| 41 | the GNU malloc behavior, where malloc (0) != NULL unless we're |
| 42 | out of storage? If not, we can omit malloc-gnu; but for now I left |
| 43 | it in to be safe. |
| 44 | (vc_ignore): Remove. |
| 45 | * README-hacking: Renamed from HACKING, since gnulib bootstrap now |
| 46 | uses that convention. |
| 47 | |

| 72 | -Werror: fix for rules useless in parser after conflicts. |
| 73 | * NEWS (2.4.3): Document fix. |

| 75 | error messages so warn and warn_at can be used in more cases. |
| 76 | * src/gram.c (grammar_rules_useless_report): Use warn_at so that |
| 77 | -Werror is always obeyed. |
| 78 | * src/reduce.c (reduce_print): Use warn so that the "warnings |
| 79 | being treated as errors" message is printed consistently before |
| 80 | the first warning message. This makes testing easier. |
| 81 | * tests/local.at (AT_BISON_WERROR_MSG): New macro. |
| 82 | (AT_BISON_CHECK_NO_XML): Extend to check -Werror and |
| 83 | --warnings=error when warnings appear in bison's stderr. |
| 84 | |
| 85 | 2010-07-29 Joel E. Denny <joeldenny@joeldenny.org> |
| 86 | |
| 87 | maint: enable gnits only at stable releases. |
| 88 | * configure.ac (AM_INIT_AUTOMAKE): Underscore or dash in a |
| 89 | version string should disable gnits. Explain in comments. |

| 113 | tests: handle Valgrind that complains about >&-. |
| 114 | * tests/output.at (AT_CHECK_OUTPUT): Extend to accept pre-tests. |
| 115 | (Output files: -dv >&-): Skip test group if running |
| 116 | maintainer-check-valgrind. |
| 117 | |

| 447 | portability: fix several issues with M4 subprocess. |
| 448 | |
| 449 | M4's output pipe was not being drained upon fatal errors during |
| 450 | scan_skel. As a result, broken-pipe messages from M4 were seen |
| 451 | on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a |
| 452 | failure in the test suite. The problem was that, on platforms |
| 453 | where the default disposition for SIGPIPE is ignore instead of |
| 454 | terminate, M4 sometimes saw fwrite fail with errno=EPIPE and |
| 455 | then reported it. However, there's some sort of race condition, |
| 456 | because the new test group occasionally succeeded. |
| 457 | Reported by Albert Chin at |

| 463 | Switching to create_pipe_bidi suggested by Akim Demaille. |
| 464 | |
| 465 | To attempt to solve both of these problems, switch to gnulib's |
| 466 | create_pipe_bidi and register M4 process as a slave. Along the |
| 467 | way, clean up file name conflict handling, which was affected by |
| 468 | the broken-pipe problem before the switch. |

| 481 | the output file name with /dev/null. Use the /dev/null solution |
| 482 | for the case of two conflicting output files as well because it |

| 661 | Fix handling of yychar manipulation in user semantic actions. |
| 662 | The problem was that yacc.c didn't always update the yychar |
| 663 | translation afterwards. However, other skeletons appear to be |
| 664 | fine. glr.c appears to already translate yychar before every |
| 665 | use. lalr1.cc does not define yychar and does not document its |
| 666 | replacement, yyla, for users. It does provide yyclearin, but |
| 667 | that does not manipulate yyla and thus requires no translation |
| 668 | update. In lalr1.java, yychar is out of scope during semantic |
| 669 | actions. |
| 670 | * NEWS (2.5): Document. |
| 671 | * data/yacc.c (YYBACKUP): Don't bother translating yychar into |
| 672 | yytoken here. |

| 674 | yytoken, and add comments explaining this approach. |
| 675 | * tests/actions.at (Destroying lookahead assigned by semantic |
| 676 | action): New test group checking that translation happens before |
| 677 | lookahead destructor calls at parser return. Previously, |
| 678 | incorrect destructors were called. |
| 679 | * tests/conflicts.at (%error-verbose and consistent |
| 680 | errors): New test group checking that translation happens at |
| 681 | syntax error detection before the associated verbose error |
| 682 | message and the associated lookahead destructor calls. While |
| 683 | the destructor call is fixed by this patch, the verbose error |
| 684 | message is currently incorrect due to another bug (see |

| 764 | * bootstrap.conf (gnulib_modules): Add all the printf modules |
| 765 | suggested by -DGNULIB_POSIXCHECK. Add realloc-posix as |
| 766 | suggested by -DGNULIB_POSIXCHECK for gnulib's own vasnprintf.c. |
| 767 | (excluded_files): Remove m4/printf-posix.m4. |
| 768 | * tests/atlocal.in (LIBS): As for LDADD in src/local.mk, add |
| 769 | lib/libbison.a so gnulib libraries can be linked. |
| 770 | |
| 771 | 2009-12-14 Joel E. Denny <jdenny@clemson.edu> |
| 772 | |
| 773 | Enable assertion output and --disable-assert for configure. |
| 774 | * bootstrap.conf (gnulib_modules): Add assert module. |
| 775 | * src/system.h (aver): Define as assert, and summarize the |
| 776 | discussion on this issue. |
| 777 | |
| 778 | 2009-12-14 Joel E. Denny <jdenny@clemson.edu> |
| 779 | |

| 797 | of char*. |
| 798 | (Sbitset__isEmpty): Use Sbitset instead of char*. |
| 799 | * src/Sbitset.h (Sbitset): Make it a pointer to unsigned char |
| 800 | instead of char. This helps to avoid casting errors. |
| 801 | (Sbitset__or): Use Sbitset instead of char*. |
| 802 | |
| 803 | 2009-10-16 Joel E. Denny <jdenny@clemson.edu> |
| 804 | |
| 805 | portability: don't assume 8-bit bytes. |
| 806 | That is, use CHAR_BIT and UCHAR_MAX instead of 8 and 0xff. |
| 807 | * src/Sbitset.h (Sbitset__nbytes): Here. |
| 808 | (Sbitset__byteAddress): Here. |
| 809 | (Sbitset__bit_mask): Here. |

| 813 | |
| 814 | 2009-10-11 Joel E. Denny <jdenny@clemson.edu> |
| 815 | |
| 816 | portability: use va_start and va_end in the same function. |
| 817 | * src/complain.c (error_message): Move va_end from here... |
| 818 | (ERROR_MESSAGE): ... to here. |
| 819 | |
| 820 | 2009-10-08 Joel E. Denny <jdenny@clemson.edu> |
| 821 | |
| 822 | * data/bison.m4: Update comments for rename to muscle-tab.h. |

| 824 | 2009-10-08 Joel E. Denny <jdenny@clemson.edu> |
| 825 | |
| 826 | Rename muscle_tab.* to muscle-tab.* for consistency with master. |
| 827 | * src/Makefile.am (bison_SOURCES): Update. |
| 828 | * src/getargs.c, src/ielr.c, src/lalr.c, src/main.c, |
| 829 | src/output.c, src/parse-gram.y, src/print.c, src/reader.c, |
| 830 | src/tables.c: Update include. |
| 831 | * src/muscle_tab.c, src/muscle_tab.h: Rename to... |
| 832 | * src/muscle-tab.c, src/muscle-tab.h: ... these and update |
| 833 | include. |
| 834 | |
| 835 | 2009-10-07 Joel E. Denny <jdenny@clemson.edu> |
| 836 | |
| 837 | Minor code cleanup. |

| 839 | replace all uses with UNIQSTR_CONCAT. |
| 840 | * src/uniqstr.c (uniqstr_vsprintf): New function. |
| 841 | * src/uniqstr.h (uniqstr_vsprintf): Add prototype. |
| 842 | (UNIQSTR_CONCAT, UNIQSTR_GEN_FORMAT, UNIQSTR_GEN_FORMAT_): New |
| 843 | macros. |
| 844 | |
| 845 | 2009-10-04 Joel E. Denny <jdenny@clemson.edu> |
| 846 | |
| 847 | Minor code cleanup. |
| 848 | * src/parse-gram.y: Clean up sorting of declarations. |
| 849 | Use types to simplify %printer declarations where possible. |

| 851 | * src/symtab.c: Whitespace change. |
| 852 | |
| 853 | 2009-10-04 Joel E. Denny <jdenny@clemson.edu> |
| 854 | |
| 855 | tests: skip tests of file names that platform does not support. |
| 856 | Reported by Michael Raskin at |
| 857 | <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00001.html>. |
| 858 | * THANKS (Michael Raskin): Add. |
| 859 | * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix. Cygwin used |
| 860 | to fail at least for file names containing ":" or "\". |
| 861 | |
| 862 | 2009-09-23 Joel E. Denny <jdenny@clemson.edu> |
| 863 | |
| 864 | yysyntax_error: avoid duplicate lookahead collection. |
| 865 | Except when memory reallocation is required, this change |
| 866 | eliminates the need to invoke yysyntax_error twice and thus to |
| 867 | repeat the collection of lookaheads. It also prepares for |
| 868 | future extensions that will make those repetitions more |
| 869 | expensive and that will require additional memory management in |
| 870 | yysyntax_error. Finally, it fixes an obscure bug already |
| 871 | exercised in the test suite. |
| 872 | * data/yacc.c (yysyntax_error): Add arguments for message |
| 873 | buffer variables stored in the parser. Instead of size, return |
| 874 | status similar to yyparse status but indicating success of |
| 875 | message creation. Other than the actual reallocation of the |
| 876 | message buffer, import and clean up memory management code |
| 877 | from... |
| 878 | (yyparse, yypush_parse): ... here. |
| 879 | * tests/regression.at (%error-verbose overflow): No longer an |
| 880 | expected failure. |
| 881 | |
| 882 | 2009-09-23 Joel E. Denny <jdenny@clemson.edu> |
| 883 | |
| 884 | yysyntax_error: test memory management more. |
| 885 | * tests/atlocal.in (NO_WERROR_CFLAGS): New cpp macro. |
| 886 | * tests/regression.at (%error-verbose and YYSTACK_USE_ALLOCA): |
| 887 | New test group. |
| 888 | (%error-verbose overflow): New test group that reveals an |
| 889 | obscure bug. Expected fail for now. |
| 890 | |
| 891 | 2008-12-11 Akim Demaille <demaille@gostai.com> |
| 892 | |
| 893 | Pass the token type to yysyntax_error. |
| 894 | * data/yacc.c (yysyntax_error): Take the transated token instead |
| 895 | of the raw number. |
| 896 | Adjust callers. |
| 897 | |
| 898 | 2008-12-11 Akim Demaille <demaille@gostai.com> |
| 899 | |
| 900 | Simplify the i18n of the error messages. |
| 901 | * data/yacc.c (yysyntax_error): Rewrite, using a switch instead |
| 902 | of building dynamically the format string. |
| 903 | |
| 904 | 2009-10-03 Joel E. Denny <jdenny@clemson.edu> |
| 905 | |
| 906 | Remove dead code. |
| 907 | * src/symtab.c (symbol_pack): Here because every symbol's number |
| 908 | is always defined by this time. |
| 909 | |
| 910 | 2009-10-03 Alex Rozenman <rozenman@gmail.com> |
| 911 | |
| 912 | Add additional space after periods in NEWS. |
| 913 | * NEWS (2.5): here. |
| 914 | |
| 915 | 2009-09-29 Joel E. Denny <jdenny@clemson.edu> |
| 916 | |
| 917 | Use the correct conversion specifier for size_t. |
| 918 | Reported by Jim Meyering. |
| 919 | * src/Sbitset.h (SBITSET__INDEX__CONVERSION_SPEC): New, "zu" |
| 920 | because Sbitset__Index is size_t. |
| 921 | * src/Sbitset.c (Sbitset__fprint): Use it instead of %d. |
| 922 | |
| 923 | 2009-09-27 Joel E. Denny <jdenny@clemson.edu> |
| 924 | |
| 925 | tests: don't abuse AT_BISON_CHECK. |
| 926 | * tests/regression.at (parse-gram.y: LALR = IELR): Move |
| 927 | additional shell commands outside of AT_BISON_CHECK. |
| 928 | |
| 929 | 2009-09-26 Joel E. Denny <jdenny@clemson.edu> |
| 930 | |
| 931 | tests: check that parse-gram.y's IELR and LALR are identical. |
| 932 | * tests/atlocal.in (abs_top_srcdir): New shell variable. |
| 933 | * tests/regression.at (parse-gram.y: LALR = IELR): New test |
| 934 | group. |
| 935 | |
| 936 | 2009-09-16 Akim Demaille <demaille@gostai.com> |
| 937 | |

| 961 | |
| 962 | 2009-09-13 Joel E. Denny <jdenny@clemson.edu> |
| 963 | |
| 964 | tests: clean up push.at test group titles. |
| 965 | * tests/push.at: Remove "Push Parsing: " from test group titles |
| 966 | because these are already under the banner "Push Parsing Tests". |
| 967 | |
| 968 | 2009-09-12 Alex Rozenman <rozenman@gmail.com> |
| 969 | |
| 970 | Provide an additional sub-message for clarity. |
| 971 | Add "symbol not found in production" error message when |
| 972 | an "invalid reference" is detected in named references |
| 973 | resolution. |
| 974 | * src/scan-code.l: Update "invalid reference" case. |
| 975 | * tests/named-ref.at: Adjust test-cases. |
| 976 | |
| 977 | 2009-09-10 Joel E. Denny <jdenny@clemson.edu> |
| 978 | |
| 979 | Clean up yacc.c a little. |
| 980 | * data/yacc.c: Clean up M4 for readability, and make output |
| 981 | whitespace more consistent. For the main parse function |
| 982 | comment, instead of saying "yyparse or yypush_parse", say either |
| 983 | "yyparse" or "yypush_parse" depending on which it actually is. |
| 984 | |
| 985 | 2009-09-03 Joel E. Denny <jdenny@clemson.edu> |
| 986 | |
| 987 | Complain about unused %define variables and %code qualifiers. |
| 988 | * NEWS (2.5): Document. |
| 989 | * data/bison.m4 (b4_check_user_names): Complain instead of warn. |
| 990 | * doc/bison.texinfo (Decl Summary): Document complaint, and |
| 991 | improve %define documentation a little otherwise. |
| 992 | * tests/input.at (Reject unused %code qualifiers): Update. |
| 993 | (%define errors): Update. |
| 994 | (%define, --define, --force-define): Update. |

| 998 | |
| 999 | 2009-09-03 Joel E. Denny <jdenny@clemson.edu> |
| 1000 | |
| 1001 | Use aver not assert. |
| 1002 | * src/output.c: Don't include assert.h. |
| 1003 | (output_skeleton): Use aver not assert. |
| 1004 | * src/system.h (aver): In documentation of why, add links to |
| 1005 | Paul Eggert's explanations in the mailing lists. |
| 1006 | |
| 1007 | 2009-09-05 Alex Rozenman <rozenman@gmail.com> |
| 1008 | |
| 1009 | Use "Unresolved reference" error message when no symbols were found |
| 1010 | in a symbolic reference resolution. Remove .expr and -expr from |
| 1011 | the shown reference when the reference is unresolved. |
| 1012 | * src/scan-code.l: Change the error message, adjust location columns, |
| 1013 | rename variable "exact_mode" to "explicit_bracketing". |
| 1014 | * tests/named-ref.at: Adjust existing tests and add a new one. |
| 1015 | |
| 1016 | 2009-09-03 Akim Demaille <demaille@gostai.com> |
| 1017 | |

| 1019 | |
| 1020 | 2009-09-03 Akim Demaille <demaille@gostai.com> |
| 1021 | |
| 1022 | bootstrap: fix/improve find_tool. |
| 1023 | * bootstrap (find_tool): Improve error messages. |
| 1024 | Fix typo about find_tool_names. |
| 1025 | |
| 1026 | 2009-08-29 Joel E. Denny <jdenny@clemson.edu> |
| 1027 | |
| 1028 | Fix gcc 3.4.4 shadowing warning reported by Eric Blake. |
| 1029 | See |
| 1030 | <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00093.html>. |
| 1031 | * src/scan-code.h (code_props_rule_action_init): Rename |
| 1032 | named_ref arg to name so it doesn't shadow named_ref type. This |
| 1033 | makes it consistent with the function definition in scan-code.l |
| 1034 | anyway. |
| 1035 | |
| 1036 | 2009-08-28 Joel E. Denny <jdenny@clemson.edu> |
| 1037 | |
| 1038 | %define: accept unquoted values. |
| 1039 | * NEWS (2.5): Group all %define changes together, and document |
| 1040 | this one. Remove quotes in IELR and canonical LR entry. |
| 1041 | * doc/bison.texinfo: Remove quotes in most examples throughout. |
| 1042 | (Decl Summary): Update %define documentation. |
| 1043 | (Table of Symbols): Likewise. |

| 1054 | 2009-08-28 Joel E. Denny <jdenny@clemson.edu> |
| 1055 | |
| 1056 | %define lr.type: make values lowercase IDs. |
| 1057 | That is, "LALR" => "lalr", "IELR" => "ielr", and |
| 1058 | "canonical LR" => "canonical-lr". |
| 1059 | * NEWS (2.5): Update documentation. |
| 1060 | * doc/bison.texinfo (Decl Summary): Likewise. |

| 1062 | * src/ielr.h (ielr): Update documentation. |
| 1063 | * src/reader.c (prepare_percent_define_front_end_variables): Use |
| 1064 | and validate new values. |

| 1066 | grammars. |
| 1067 | * tests/reduce.at (AT_TEST_LR_TYPE): Likewise. |

| 1070 | |
| 1071 | scan-gram: avoid portability trap with ctype usage. |
| 1072 | * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): |
| 1073 | Avoid compiler warning. |
| 1074 | |
| 1075 | 2009-08-27 Joel E. Denny <jdenny@clemson.edu> |
| 1076 | |
| 1077 | tests: use perl for printing special sequences to files. |
| 1078 | And skip tests if perl is not available. This is better than |
| 1079 | playing tricks with shell portability. Suggested by Akim |
| 1080 | Demaille. |
| 1081 | * tests/input.at (Bad character literals): Use it here for |
| 1082 | omitting final newlines. |
| 1083 | (Bad escapes in literals): Use it here for special characters. |
| 1084 | |
| 1085 | 2009-08-26 Joel E. Denny <jdenny@clemson.edu> |
| 1086 | |
| 1087 | tests: show a use of %define lr.default-reductions "consistent" |
| 1088 | * tests/conflicts.at (%nonassoc and eof): Extend to test that it |
| 1089 | prevents the omission of expected tokens for %error-verbose. |
| 1090 | |
| 1091 | 2009-08-26 Akim Demaille <demaille@gostai.com> |
| 1092 | |
| 1093 | tests: portability fix. |
| 1094 | * tests/input.at (Bad escapes in literals): Don't expect "echo |
| 1095 | '\0'" to output \ then 0. |
| 1096 | |
| 1097 | 2009-08-26 Joel E. Denny <jdenny@clemson.edu> |
| 1098 | |
| 1099 | Actually handle the yytable zero value correctly this time. |
| 1100 | * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Don't |
| 1101 | mention zero values in the YYTABLE comments. |
| 1102 | * data/glr.c (yytable_value_is_error): Don't check for zero |
| 1103 | value. |
| 1104 | * data/lalr1.cc (yy_table_value_is_error_): Likewise. |
| 1105 | * data/yacc.c (yytable_value_is_error): Likewise. |
| 1106 | * data/lalr1.java (yy_table_value_is_error_): Likewise. |
| 1107 | (yysyntax_error): Fix typo in code: use yytable_ not yycheck_. |
| 1108 | * src/tables.h: In header comments, explain why it's useless to |
| 1109 | check for a zero value in yytable. |
| 1110 | |
| 1111 | 2009-08-25 Joel E. Denny <jdenny@clemson.edu> |
| 1112 | |
| 1113 | More fixes related to last two patches. |
| 1114 | * data/c.m4 (b4_table_value_equals): Comment that YYID must be |
| 1115 | defined. |
| 1116 | * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix |
| 1117 | yytable comments: zero indicates syntax error not default |
| 1118 | action. |
| 1119 | * data/glr.c (yyis_pact_ninf): Rename to... |
| 1120 | (yypact_value_is_default): ... this. |
| 1121 | (yyisDefaultedState): Update for rename. |
| 1122 | (yyis_table_ninf): Rename to... |
| 1123 | (yytable_value_is_error): ... this, and check for value zero |
| 1124 | besides just YYTABLE_NINF. |
| 1125 | (yygetLRActions): Check for default value from yypact. It |
| 1126 | appears that this check is always performed before this function |
| 1127 | is invoked, and so adding the check here is probably redundant. |
| 1128 | However, the code may evolve after this subtlety is forgotten. |
| 1129 | Also, update for rename to yytable_value_is_error. Because that |
| 1130 | macro now checks for zero, a different but equivalent branch of |
| 1131 | the if-then-else here is evaluated. |
| 1132 | (yyreportSyntaxError): Update for rename to |
| 1133 | yytable_value_is_error. The zero condition was mishandled |
| 1134 | before. |
| 1135 | (yyrecoverSyntaxError): Update for renames. No behavioral |
| 1136 | changes. |
| 1137 | * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_): |
| 1138 | New function. |
| 1139 | (yy_table_value_is_error_): New function. |
| 1140 | (parse): Use new functions where possible. No behavioral |
| 1141 | changes. |
| 1142 | (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_. |
| 1143 | The zero condition was mishandled before. |
| 1144 | * data/yacc.c (yyis_pact_ninf): Rename to... |
| 1145 | (yypact_value_is_default): ... this. |
| 1146 | (yyis_table_ninf): Rename to... |
| 1147 | (yytable_value_is_error): ... this, and check for value zero |
| 1148 | besides just YYTABLE_NINF. |
| 1149 | (yysyntax_error): Update for rename to yytable_value_is_error. |
| 1150 | The zero condition was mishandled before. |
| 1151 | (yyparse): Update for renames. No behavioral changes. |
| 1152 | * src/tables.h: Improve comments about yypact, yytable, etc. |
| 1153 | more. Most importantly, say yytable value of zero means syntax |
| 1154 | error not default action. |

| 1188 | * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): Use |
| 1189 | quote rather than implementing quoting here. |
| 1190 | |
| 1191 | 2009-08-20 Eric Blake <ebb9@byu.net> |
| 1192 | |
| 1193 | Make previous patch more robust. |
| 1194 | * src/output.c (ARRAY_CARDINALITY): New macro, copied from |

| 1207 | Fix complaints about escape sequences. |
| 1208 | Discussed starting at |
| 1209 | <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>. |
| 1210 | * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): |
| 1211 | For a \0 and similar escape sequences meaning the null |
| 1212 | character, report an invalid escape sequence instead of an |
| 1213 | invalid null character because the latter does not actually |
| 1214 | appear in the user's input. |
| 1215 | In all escape sequence complaints, don't escape the initial |
| 1216 | backslash, and don't quote when the sequence appears at the end |
| 1217 | of the complaint line unless there's whitespace that quotearg |
| 1218 | won't escape. |
| 1219 | Consistently say "invalid" not "unrecognized". |
| 1220 | Consistently prefer "empty character literal" over "extra |
| 1221 | characters in character literal" warning for invalid escape |
| 1222 | sequences; that is, consistently discard those sequences. |
| 1223 | * tests/input.at (Bad escapes in literals): New. |

| 1257 | |
| 1258 | build: lower gettext requirements. |
| 1259 | |
| 1260 | Bison was uselessly requiring the formatstring macros from |
| 1261 | gettext, which resulted in mo files not being installed on systems |
| 1262 | that perfectly supported Bison mo files. Lower the requirement. |
| 1263 | http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html |
| 1264 | |
| 1265 | * configure.ac: Require need-ngettext instead of |
| 1266 | need-formatstring-macros. |

| 1283 | Make it easier to write deterministic tests. |
| 1284 | Continues Akim's work from his 2009-06-10 commits. |
| 1285 | * src/reader.c (check_and_convert_grammar): Don't add any |
| 1286 | symbols after the first symbols_do invocation. |
| 1287 | * src/symtab.c (symbols_sorted): New static global. |
| 1288 | (user_token_number_redeclaration): Update comments. |
| 1289 | (symbol_from_uniqstr): If a new symbol is being created, assert |
| 1290 | that symbols_sorted hasn't been allocated yet. |
| 1291 | (symbols_free): Free symbols_sorted. |
| 1292 | (symbols_cmp, symbols_cmp_qsort): New functions. |
| 1293 | (symbols_do): Sort symbol_table into symbols_sorted on first |
| 1294 | invocation. |
| 1295 | * tests/input.at (Numbered tokens): Recombine tests now that the |
| 1296 | output should be deterministic across multiple numbers. |

| 1304 | 2009-08-10 Joel E. Denny <jdenny@clemson.edu> |

| 1308 | 2009-08-10 Joel E. Denny <jdenny@clemson.edu> |
| 1309 | |
| 1310 | Miscellaneous code readability improvements. |
| 1311 | |
| 1312 | * src/reader.c (reader): Move %define front-end variable |
| 1313 | defaults and checking into... |
| 1314 | (prepare_percent_define_front_end_variables): ... this new |
| 1315 | function. |
| 1316 | |
| 1317 | * src/scan-gram.l (INITIAL): For consistency with string |
| 1318 | literals, don't store open quote on character literal. It's |
| 1319 | discarded before returning anyway. |
| 1320 | (SC_ESCAPED_CHARACTER): Similarly, don't store close quote. |
| 1321 | Make length test more readable, and make the character stored |
| 1322 | for an empty literal more obvious while consistent with the |
| 1323 | previous behavior. |
| 1324 | |
| 1325 | * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to |
| 1326 | USER_NUMBER_HAS_STRING_ALIAS throughout. |
| 1327 | * src/symtab.c (symbol_make_alias): Remove comment from symtab.c |
| 1328 | that is repeated in symtab.h. Improve argument names to make it |
| 1329 | clear which side of the symbol-string alias pair is which. |
| 1330 | (symbol_check_alias_consistency): Improve local variable names |
| 1331 | for the same purpose. |
| 1332 | * src/symtab.h (struct symbol): Make comments about aliases |
| 1333 | clearer. |
| 1334 | (symbol_make_alias): Improve comments and argument name. |
| 1335 | * src/output.c (token_definitions_output): Update for rename to |
| 1336 | USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases. |
| 1337 | |

| 1404 | Reported by Alex Rozenman. This warning shows up with gcc-4.3.0 |
| 1405 | and later. |
| 1406 | * src/scan-code.l: Add "%option noinput", which I cannot find in |
| 1407 | the Flex manual, but which Flex has supported since at least as |
| 1408 | far back as 2.5.4. However, if any of our developers still use |
| 1409 | Flex 2.5.4, they'll need to stop configuring with |
| 1410 | --enable-gcc-warnings because "%option noinput" didn't work |
| 1411 | correctly until Flex 2.5.6. |

| 1452 | Suggested by Eric Blake at |
| 1453 | <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>. |
| 1454 | * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not |
| 1455 | complicate the code by distinguishing between a missing value |
| 1456 | and an empty string value for an optional argument. This fix is |
| 1457 | allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below. |
| 1458 | * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into... |
| 1459 | (AT_TEST_TABLES_AND_PARSE): ... this now that the special |
| 1460 | arguments are not needed because of the following changes. |
| 1461 | Fix stale comments. |
| 1462 | Bison developers should use GNU M4 and should not use |
| 1463 | POSIXLY_CORRECT when building the test suite, so do not |
| 1464 | complicate the code by avoiding $10 and above. |
| 1465 | Do not quote an empty string value for an optional argument, and |

| 1562 | deterministic test suite. |
| 1563 | Some consistency checks on symbols are performed after all the |
| 1564 | symbols were read, by an iteration over the symbol table. This |
| 1565 | traversal is nondeterministic, which can be a problem for test |
| 1566 | cases. |
| 1567 | Avoid this. |
| 1568 | Addresses another form of nondeterminism reported by Joel E. Denny. |

| 1651 | |
| 1652 | Handle a trailing `:' in a user-supplied C++ namespace better. |
| 1653 | * data/c++.m4 (b4_namespace_close): Don't let it be printed |
| 1654 | among the closing braces here. This fix might make the |
| 1655 | generated code easier to debug, but otherwise it should be |
| 1656 | insignificant because a trailing `:' is a C++ error already. |
| 1657 | |

| 1659 | |

| 1723 | think of a better place to expose it. My logic is that, for all |
| 1724 | uses of tr so far, command-line arguments can be involved, and |
| 1725 | getargs.h is already included. |

| 1850 | restrictions. |

| 1852 | when trying to distinguish from GLR. Talk about LR(1) grammars |
| 1853 | rather than LALR(1) grammars. |
| 1854 | (Decl Summary): In %define api.push_pull entry, say it applies |
| 1855 | to deterministic parsers in C rather than LALR(1) parsers in C. |
| 1856 | Add lr.default_rules entry. |
| 1857 | Add lr.type entry. |
| 1858 | (Mystery Conflicts): Bison is no longer limited to LALR(1) |
| 1859 | restrictions. |
| 1860 | (Generalized LR Parsing): Same changes as for the previous GLR |
| 1861 | section. |
| 1862 | (Memory Management): Say deterministic rather than LALR(1). |
| 1863 | (Understanding): Correct some bison output. |

| 1880 | 2009-04-21 Joel E. Denny <jdenny@ces.clemson.edu> |

| 1899 | handled in ielr. |
| 1900 | (initialize_LA): Export it. Move lookback allocation to... |

| 1902 | be invoked but lookback and much of the rest of LALR isn't |
| 1903 | needed. |
| 1904 | * main.c (main): Instead of lalr, invoke ielr, which invokes |
| 1905 | lalr. |

| 2679 | Partial m4sugar merge from autoconf: builtins, version.m4. |
| 2680 | * data/m4sugar/m4sugar.m4 (changeword): Nuke. |
| 2681 | (m4_prepend): Remove, as it is unused and inherently quadratic, |
| 2682 | whereas m4_append is linear in newer m4. |
| 2683 | (m4_mkstemp): New builtin. |
| 2684 | (m4_symbols): Make rename conditional. |
| 2685 | (m4_version_prereq): Ensure fatal error if used in bison, which |

| 2719 | Remove remaining dependence on CVS Id keyword. |
| 2720 | * ChangeLog: For the sake of people still using CVS, don't use dollars |

| 2722 | * data/xslt/bison.xsl: Remove Id from header comments, where it was |
| 2723 | unusual anyway. |
| 2724 | * data/xslt/xml2dot.xsl: Likewise. |

| 2732 | |
| 2733 | 2008-07-27 Joel E. Denny <jdenny@ces.clemson.edu> |
| 2734 | |
| 2735 | Fix dependence on computed configure variables. |
| 2736 | * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not |
| 2737 | $(top_srcdir)/configure.ac so that changes to computed variables, such |
| 2738 | as PACKAGE_VERSION, are seen. |
| 2739 | * tests/Makefile.am ($(srcdir)/package.m4): Likewise. |
| 2740 | |
| 2741 | 2008-07-20 Joel E. Denny <jdenny@ces.clemson.edu> |

| 2759 | * Makefile.am: Add code suggested by comments in |
| 2760 | build-aux/git-version-gen. |
| 2761 | (EXTRA_DIST): Remove GNUmakefile, handled by Gnulib. Add maint.mk, |
| 2762 | .prev-version, and .version. |
| 2763 | * NEWS (2.3b+): Rename to... |
| 2764 | (?.?): ... this because we're dropping the "+" version naming scheme, |
| 2765 | but, in general, we still can't be sure of our next release name. |
| 2766 | * bootstrap: Add a quick hack to remove from .gitignore the |
| 2767 | GNUmakefile entry that gnulib adds. We already have a /GNUmakefile |
| 2768 | entry. This should really be fixed in gnulib instead. |
| 2769 | * bootstrap.conf (gnulib_modules): Add gnumakefile. |
| 2770 | * configure.ac (AC_INIT): Set version name by invoking |

| 2800 | |
| 2801 | Fix some .gitignore and .cvsignore problems. |
| 2802 | * bootstrap (insert_sorted_if_absent): Replace all uses with... |
| 2803 | (insert_vc_ignore): ... this new function, which prepends `/' to all |
| 2804 | .gitignore entries before passing them to insert_sorted_if_absent. |
| 2805 | * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that |
| 2806 | .cvsignore files are maintained even though Bison developers run |
| 2807 | bootstrap while using Git. |
| 2808 | * .cvsignore (*.patch *.log log patches applied): Remove, apparently |
| 2809 | unneeded by Bison. |
| 2810 | (gnulib): Add. |
| 2811 | * .gitignore (/*.patch *.log log patches applied): Remove, broken and |
| 2812 | unneeded. Reported by Eric Blake. |
| 2813 | * lib/.gitignore (/*~): Add. |
| 2814 | * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore. |
| 2815 | * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric |

| 2822 | <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>. |
| 2823 | * bootstrap.conf (gnulib_modules): Add unsetenv. |
| 2824 | * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add. |
| 2825 | * m4/.gitignore, m4/.cvsignore (/environ.m4): Add. |
| 2826 | (/setenv.m4): Add. |
| 2827 | * src/output.c (output_skeleton): For the m4 invocation, pass -dV as |
| 2828 | the first argument because it may become position-dependent, and unset |
| 2829 | POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions. |
| 2830 | Add comments explaining these issues in more detail. |
| 2831 | |
| 2832 | 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu> |

| 2892 | 2008-04-23 Eric Blake <ebb9@byu.net> |
| 2893 | |
| 2894 | Revert prior patch, by working around autoconf regression. |
| 2895 | * tests/output.at (m4_expand): Add workaround for autoconf 2.62. |
| 2896 | ("Output file name: ("): Uncomment test. |
| 2897 | ("Output file name: )"): Likewise. |
| 2898 | Based on an idea from Noah Misch. |
| 2899 | |
| 2900 | 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 2901 | |
| 2902 | Work-around an Autoconf 2.62 AT_SETUP bug that was not present in |
| 2903 | 2.61. Reported by Juan Manuel Guerrero at |
| 2904 | <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>. |
| 2905 | * tests/output.at ("Output file name: ("): Comment out test case for |
| 2906 | now. |
| 2907 | ("Output file name: )"): Likewise. |
| 2908 | |
| 2909 | 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 2910 | |
| 2911 | * GNUmakefile: Update git-version-gen invocation so make dist |
| 2912 | succeeds. |
| 2913 | |
| 2914 | 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 2915 | |
| 2916 | Update to the current gnulib CVS repository, and fix trigraph handling |
| 2917 | in Bison. |
| 2918 | * bootstrap: Update gnulib CVS repository URL. |
| 2919 | (symlink_to_dir): Encapsulate the code that guarantees the destination |
| 2920 | directory exists into... |
| 2921 | (check_dst_dir): ... this new function, and... |
| 2922 | (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't |
| 2923 | fail when copying files into lib/uniwidth/. |
| 2924 | * src/output.c (prepare_symbols): When writing yytname muscles, where |
| 2925 | symbol names will be encoded in C-string literals, tell quotearg to |
| 2926 | escape trigraphs. This used to be the default in gnulib. |
| 2927 | * tests/regression.at (Token definitions): Because of the change in |
| 2928 | gnulib's quotearg behavior, string_as_id in parse-gram.y no longer |
| 2929 | escapes trigraphs in symbol names. Thus, yytname no longer has |
| 2930 | trigraphs unnecessarily doubly escaped. Update test case output. |
| 2931 | Extend test case to be sure Bison's own error messages will no longer |
| 2932 | have trigraphs in symbol names unnecessarily escaped once. |
| 2933 | |

| 2947 | * doc/bison.texinfo (Bison Options): Reword -W entry a little for |
| 2948 | consistency. Update the -g and -x entries now that they take |
| 2949 | arguments. Use brackets to indicate optional arguments. |
| 2950 | * src/getargs.c (usage): Explain the relationship between arguments of |
| 2951 | long and short options more completely. Document --defines and -d |
| 2952 | separately since the former takes an argument but, for POSIX Yacc, the |
| 2953 | latter does not. |
| 2954 | (short_options): Let -W take an optional argument like --warnings. |
| 2955 | (getargs): Sort cases. |

| 2965 | |
| 2966 | 2008-02-28 Akim Demaille <akim@epita.fr> |
| 2967 | |
| 2968 | * src/getargs.c (short_options): Split and sort for readability. |
| 2969 | -g and -x take optional arguments, just like their long options. |
| 2970 | * build-aux/cross-options.pl: Use /x to make the regexp easier to |
| 2971 | understand. |
| 2972 | Fix the handling of $opt which resulted in all the argument to be |
| 2973 | considered as optional. |
| 2974 | |

| 2995 | * NEWS (2.3a+): Mention XML support, and say the schema is |

| 3012 | (yypstate_allocated): Define for impure push parsers regardless of |
| 3013 | whether the pull interface is also requested. |

| 3015 | check impure push parsers without the pull interface. |
| 3016 | |
| 3017 | * data/yacc.c (yypstate_new): Don't try to invoke yyerror since |
| 3018 | yyerror takes arguments specified by %parse-param while yypstate_new |
| 3019 | does not. |
| 3020 | * doc/bison.texinfo (Parser Create Function): Document that |

| 3473 | |
| 3474 | * data/xslt/xml2dot.xsl (xsl:template match="automaton/state"): After |

| 3548 | |
| 3549 | Make xml2dot.xsl and --graph produce the same output. |
| 3550 | * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a ` ' |

| 3552 | escaped later. |
| 3553 | (xsl:template name="output-node"): Use the new escape template instead |
| 3554 | of the string-replace template directly. |
| 3555 | (xsl:template name="output-edge"): Likewise. |

| 3560 | |
| 3561 | Make xml2text.xsl and --report produce the same output, and remove the |

| 3565 | (xsl:template match="state" mode="bison:count-conflicts): New. |
| 3566 | * data/xslt/xml2text.xsl: Import bison.xsl. |
| 3567 | (xsl:template match="bison-xml-report"): Instead of styling the |
| 3568 | "conflicts" element, style the "automaton" element with mode |
| 3569 | "conflicts". Unlike the former, the latter lists S/R and R/R |
| 3570 | conflicts for a state on the same line. |
| 3571 | (xsl:template match="conflicts"): Remove. |
| 3572 | (xsl:template match="conflict"): Remove. |

| 3585 | (xsl:template match="conflict"): Remove. |
| 3586 | (xsl:template match="automaton" mode="conflicts"): New. |
| 3587 | (xsl:template match="state" mode="conflicts): New. |
| 3588 | * src/conflicts.c (conflicts_output_xml): Remove. |
| 3589 | * src/conflicts.h (conflicts_output_xml): Remove prototype. |
| 3590 | * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml. |
| 3591 | * src/print.c (print_grammar): Consistently wrap at the 66th column so |
| 3592 | the corresponding XSLT is easier. Also, never wrap between a word and |
| 3593 | the comma that follows it. |
| 3594 | |
| 3595 | 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu> |

| 3597 | Improve C++ namespace support. Discussed starting at |
| 3598 | <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>. |
| 3599 | * data/c++.m4: (b4_namespace_ref, b4_namespace_open, |
| 3600 | b4_namespace_close): New macros that interpret the %define variable |
| 3601 | "namespace" so its value can contain "::" to indicate nested |
| 3602 | namespaces. |
| 3603 | * data/glr.cc (b4_namespace): Don't define, and replace all uses with |
| 3604 | the above macros. |
| 3605 | * data/lalr1.cc (b4_namespace): Likewise. |
| 3606 | * data/location.cc (b4_namespace): Likewise. |
| 3607 | * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry |
| 3608 | inside a new table in the general %define entry. Document `%define |
| 3609 | namespace' there as well. Point the %name-prefix entry to it since it |
| 3610 | explains it more completely in the case of C++. |
| 3611 | (C++ Bison Interface): Mention `%define namespace' instead of |
| 3612 | %name-prefix. |
| 3613 | (Table of Symbols): Remove the `%define push_pull' entry. The %define |
| 3614 | entry suffices. |
| 3615 | * tests/c++.at (Relative namespace references): New test case. |
| 3616 | (Absolute namespace references): New test case. |
| 3617 | (Syntactically invalid namespace references): New test case. |

| 3627 | (b4_percent_define_default): Record defining location as line 1 rather |
| 3628 | than 0 for the sake of synchronizing #line's, and define |
| 3629 | b4_percent_define_syncline(VARIABLE). |
| 3630 | (b4_percent_define_check_values): Use b4_percent_define_get_loc. |
| 3631 | * src/muscle_tab.c (muscle_syncline_grow): New. |
| 3632 | (muscle_code_grow): Use muscle_syncline_grow. |

| 3638 | remove some unused variables. |
| 3639 | (muscle_percent_define_default): Record defining location as line 1 |
| 3640 | rather than 0 for the sake of synchronizing #line's, and define |
| 3641 | b4_percent_define_syncline(VARIABLE). |
| 3642 | (muscle_percent_define_check_values): Use |
| 3643 | muscle_percent_define_get_loc. |
| 3644 | * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype. |
| 3645 | (muscle_percent_define_get_syncline): Prototype. |
| 3646 | * tests/skeletons.at (%define Boolean variables: invalid skeleton |
| 3647 | defaults): Update output for location change. |
| 3648 | (Complaining during macro argument expansion): Extend to test |
| 3649 | b4_percent_define_get_loc and b4_percent_define_get_syncline errors. |
| 3650 | |
| 3651 | 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3652 | |
| 3653 | Fix some error-reporting macro bugs. |
| 3654 | * data/bison.m4 (b4_cat): New. |
| 3655 | (b4_error, b4_error_at): Use b4_cat to send error directives directly |
| 3656 | to stdout so they don't become arguments to other macros. Update |
| 3657 | comments and add examples. |
| 3658 | (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and |
| 3659 | add examples. |
| 3660 | (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately |
| 3661 | after printing the error directive so that M4 doesn't report subsequent |
| 3662 | problems that are induced by this problem. |
| 3663 | * src/scan-skel.l: Recognize @` digraph outside of directive arguments |
| 3664 | instead of just in them. Recognize @\n in both places. Both expand to |
| 3665 | the empty string. Needed by b4_cat. |
| 3666 | * tests/skeletons.at (Complaining during macro argument expansion): |
| 3667 | New test case. |
| 3668 | (Fatal errors make M4 exit immediately): New test case. |
| 3669 | |
| 3670 | 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu> |

| 3674 | (PRINT_DATADIR_OPTION): New anonymous enum member. |
| 3675 | (long_options): Add entry for it. |

| 3691 | 2007-09-25 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3692 | |
| 3693 | Replace `%push-parser' and `%push-pull-parser' with |
| 3694 | `%define push_pull "push"' and `%define push_pull "both"'. |
| 3695 | `%define push_pull "pull"' is the default. |
| 3696 | * doc/bison.texinfo (Push Decl, Push Parser Function, |
| 3697 | Pull Parser Function, Parser Create Function, Parser Delete Function): |
| 3698 | Update declarations. |
| 3699 | (Decl Summary, Table of Symbols): Replace %push-parser and |

| 3701 | * data/bison.m4 (b4_percent_define_check_values): New macro. |
| 3702 | (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these |
| 3703 | definitions... |
| 3704 | * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp |
| 3705 | definitions... |
| 3706 | * data/push.c: ... to here and compute them from the value of the |
| 3707 | %define variable push_pull. |
| 3708 | * data/c-skel.m4: Instead of choosing the push.c skeleton for push |
| 3709 | parsing requests here... |
| 3710 | * data/yacc.c: ... hack this to switch to push.c any time |
| 3711 | b4_use_push_pull_flag or the %define variable push_pull is set. This |
| 3712 | will go away when we mv push.c yacc.c. |
| 3713 | * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that |
| 3714 | push parsing is not supported since unused %define variables are |
| 3715 | reported anyway. |

| 3717 | * src/muscle_tab.h (muscle_percent_define_check_values): Update |

| 3753 | |
| 3754 | 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu> |

| 3760 | local variable `sep'. |
| 3761 | |
| 3762 | 2007-09-21 Paul Eggert <eggert@cs.ucla.edu> |
| 3763 | |
| 3764 | * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used |
| 3765 | elsewhere. |
| 3766 | * src/print-xml.c: Prefer "const" after types; that's more consistent. |
| 3767 | (xml_printf): Indent just 1 space for level. |
| 3768 | (e_char, xlate_char): Remove. |
| 3769 | (xml_escape_string): Rewrite to avoid undefined behavior (used |
| 3770 | storage that was freed from the stack). |
| 3771 | (xml_escape_n): Don't bother checking for subscript error. |
| 3772 | |

| 3823 | Bruno Haible <bruno@clisp.org> |
| 3824 | |
| 3825 | * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists |
| 3826 | and is a script that invokes bison. Tighten the code. Add comments. |
| 3827 | |
| 3828 | 2007-08-28 Joel E. Denny <jdenny@ces.clemson.edu> |

| 3839 | |
| 3840 | 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3841 | |
| 3842 | In impure push mode, don't allow more than one yypstate to be allocated |
| 3843 | since multiple impure parsers would corrupt yynerrs. |
| 3844 | * data/push.c (yypstate_allocated): New static global variable |
| 3845 | initialized to 0. |
| 3846 | (yypull_parse): If yypstate_new returns 0, don't report it as memory |
| 3847 | exhaustion if yypstate_allocated is 1, but still return 2. |
| 3848 | (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is |
| 3849 | already 1. Otherwise, set it to 1. |
| 3850 | (yypstate_delete): Set it to 0. |
| 3851 | * tests/push.at (Push Parsing: Multiple impure instances): New test |
| 3852 | case. |
| 3853 | |
| 3854 | 2007-08-17 Bob Rossi <bob@brasko.net> |
| 3855 | |
| 3856 | * doc/bison.texinfo (Push Decl): Document the push parser. |

| 3864 | yypush_parse, yypull_parse, yypstate_new and yypstate_delete. |

| 3924 | |
| 3925 | Get rid of broken %no-parser, -n, and --no-parser implementation and |
| 3926 | documentation. |
| 3927 | * TODO: Don't mention them. |
| 3928 | * doc/bison.1: Likewise. |
| 3929 | * doc/bison.texinfo (Decl Summary): Likewise. |
| 3930 | (Bison Options): Likewise. |
| 3931 | (Option Cross Key): Likewise. |
| 3932 | * src/getargs.c (no_parser_flag): Remove global variable. |
| 3933 | (usage): Don't print description of -n and --no-parser. |
| 3934 | (long_options): Remove --no-parser entry here. |
| 3935 | (getargs): Remove -n case in the switch here. |
| 3936 | * src/getargs.h (no_parser_flag): Remove extern. |
| 3937 | * tests/regression.at (Web2c Actions): Remove comment that mentions |
| 3938 | --no-parser. |
| 3939 | |
| 3940 | 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3941 | |
| 3942 | * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not |
| 3943 | name user variables starting with `yy'. Just pass NULL instead of a |
| 3944 | dummy local &yylval to yypush_parse. |
| 3945 | * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables |
| 3946 | starting with `yy'. |
| 3947 | |
| 3948 | 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3949 | |
| 3950 | * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is |
| 3951 | true since it's then always used regardless of whether yyoverflow is |
| 3952 | defined. Reported by Christian Burger at |
| 3953 | <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>. |
| 3954 | * THANKS: Add Christian Burger. |
| 3955 | |
| 3956 | * ChangeLog: For changes in doc/bison.texinfo, consistently reference |
| 3957 | node names: say "Decl Summary" not "Bison Declaration Summary". |
| 3958 | |
| 3959 | 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3960 | |
| 3961 | * src/muscle_tab.c (muscle_percent_define_flag_if): In order to |
| 3962 | determine whether this function has already complained about an invalid |
| 3963 | value for a %define boolean variable, don't check whether Bison has |
| 3964 | ever examined the value. As written, the check was a tautology. |
| 3965 | Instead, record and check for this complaint using a separate muscle. |
| 3966 | |
| 3967 | 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3968 | |
| 3969 | Fix push parsing memory leak reported by Brandon Lucia at |
| 3970 | <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>. |
| 3971 | * THANKS: Add Brandon Lucia. |
| 3972 | * data/push.c (yypstate_delete): Free the stack if it was reallocated |
| 3973 | but the parse never completed and thus freed it. |
| 3974 | * tests/Makefile.am (TESTSUITE_AT): Add push.at. |
| 3975 | * tests/testsuite.at: Include push.at. |
| 3976 | * test/push.at: New. |
| 3977 | (Push Parsing: Memory Leak for Early Deletion): New test case. |
| 3978 | |
| 3979 | 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu> |
| 3980 | |
| 3981 | Improve handling of multiple S/R conflicts in the same state and of S/R |
| 3982 | conflicts involving multiple reductions. |
| 3983 | * src/conflicts.c (resolve_sr_conflict): Don't assign the error action |
| 3984 | set for a state here or Bison will abort if it is reassigned on a |
| 3985 | later conflicted reduction in the same state. |
| 3986 | Similarly, don't finalize and assign the solved conflicts report here |
| 3987 | or it will be lost if it is reassigned on a later conflicted reduction |
| 3988 | in the same state. |
| 3989 | (set_conflicts): Instead, assign them both here after all S/R conflicts |
| 3990 | in the state have been fully examined. |
| 3991 | * src/print.c (shift_set): Rename to... |
| 3992 | (no_reduce_set): ... this. |
| 3993 | (print_reductions): Update for rename, and add %nonassoc error action |
| 3994 | tokens to no_reduce_set so that, when printing the first remaining |
| 3995 | reduction on an error action token, the reduction is enclosed in |
| 3996 | brackets. |
| 3997 | (print_results): Update for rename. |
| 3998 | * tests/conflicts.at (Solved conflicts report for multiple reductions |
| 3999 | in a state): New test case. |
| 4000 | (%nonassoc error actions for multiple reductions in a state): New test |
| 4001 | case. |
| 4002 | |
| 4003 | * src/main.c (main): Don't depend on C99 features. |
| 4004 | |
| 4005 | 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4006 | |
| 4007 | * build-aux/.cvsignore: Add compile. |
| 4008 | * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and |
| 4009 | uniwidth. |
| 4010 | |
| 4011 | 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4012 | |
| 4013 | * bootstrap (slurp): Create target directories that don't exist. |
| 4014 | Specifically, we need lib/uniwidth/ because of recent Gnulib changes. |
| 4015 | |
| 4016 | 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4017 | |
| 4018 | * LR0.c (new_itemsets): Fix wording in comments: say item index rather |
| 4019 | than item number. |
| 4020 | * closure.c (closure): Likewise. |
| 4021 | * state.h (reductions): Comment sorting of rules. |
| 4022 | (state): Comment sorting of items. |
| 4023 | |
| 4024 | 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4025 | |
| 4026 | Fix C++ test cases after recent Gnulib changes. Discussed starting at |
| 4027 | <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>. |
| 4028 | * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's |
| 4029 | definition in order to avoid Gnulib headers since we don't use config.h |
| 4030 | here. |
| 4031 | * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR |
| 4032 | rather than AT_DATA so that config.h is included. |
| 4033 | |
| 4034 | 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4035 | |
| 4036 | * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF |
| 4037 | instead of fprintf. Guard these functions with #if YYDEBUG instead of |
| 4038 | #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison |
| 4039 | and so that YYFPRINTF is guaranteed to be defined here. |
| 4040 | |
| 4041 | 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4042 | |
| 4043 | * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace |
| 4044 | with... |
| 4045 | (muscle_percent_define_check_values): ... this more helpful function. |
| 4046 | Again, it's not used yet, but it will be. |
| 4047 | * src/muscle_tab.h: Likewise. |
| 4048 | |
| 4049 | Improve some comments in parser table construction. |
| 4050 | * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base. |
| 4051 | (generate_states): Don't mention ruleset, which is internal to closure. |
| 4052 | * src/closure.c (closure): Explain sorting of core and itemset, which |
| 4053 | is required for this function to behave correctly. |
| 4054 | * src/closure.h (closure): Mention sorting. |
| 4055 | |
| 4056 | 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4057 | |
| 4058 | * src/lalr.c (state_lookahead_tokens_count): For code readability, |
| 4059 | move the check for disabled transitions to an aver since conflict |
| 4060 | resolution hasn't happened yet. |
| 4061 | |
| 4062 | * src/lalr.c (state_lookahead_tokens_count): Remove the check that |
| 4063 | labels a state as inconsistent just because it has error transitions. |
| 4064 | The original form of this check appeared in revision 1.1 of lalr.c, |
| 4065 | which was committed on 1991-12-21. Now (at least), changing the |
| 4066 | consistency label on such a state appears to have no useful effect in |
| 4067 | any of the places it is examined, which I enumerate below. The key |
| 4068 | point to understanding each item in this enumeration is that a state |
| 4069 | with an error transition is labelled consistent in the first place only |
| 4070 | if it has no rules, so the check cannot matter for states that have |
| 4071 | rules. (1) Labelling a state as inconsistent will cause set_conflicts |
| 4072 | to try to identify its conflicts, and a state must have *rules* to have |
| 4073 | conflicts. (2) Labelling a state as inconsistent will affect how |
| 4074 | action_row sets the default *rule* for the state. (3) Labelling a |
| 4075 | state as inconsistent will cause build_relations to add lookback edges |
| 4076 | to *rules* in that state. |
| 4077 | * src/state.h (struct state): Word the comment for member consistent |
| 4078 | more carefully. |
| 4079 | |
| 4080 | 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4081 | |
| 4082 | Don't depend on C99 features. |
| 4083 | * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop. |
| 4084 | * src/lalr.c (lalr_update_state_numbers): Fix for-loop. |
| 4085 | * src/reader.c (check_and_convert_grammar): Fix for-loop. |
| 4086 | * src/state.c (state_mark_reachable_states): Fix for-loop. |
| 4087 | (state_remove_unreachable_states): Fix for-loop. |
| 4088 | |
| 4089 | Don't widen struct state with member reachable just to temporarily |
| 4090 | record reachability. Instead, use a local bitset. |
| 4091 | * src/state.h (struct state): Remove member. |
| 4092 | * src/state.c (state_new): Don't initialize it. |
| 4093 | (state_mark_reachable_states): Rename to... |
| 4094 | (state_record_reachable_states): ... this, and use bitset. |
| 4095 | (state_remove_unreachable_states): Use bitset. |
| 4096 | |
| 4097 | 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4098 | |
| 4099 | * src/Makefile.am (yacc): Quote target action commands properly so |
| 4100 | that the yacc script isn't corrupt. Reported by Hans Aberg at |

| 4125 | (muscle_percent_define_get, muscle_percent_define_ifdef): New |
| 4126 | functions. |
| 4127 | (muscle_percent_define_flag_if): Use muscle_percent_define_ifdef and |

| 4259 | %define and %code directives. |
| 4260 | |
| 4261 | Make it easy to share %define boolean variables between the front-end |
| 4262 | and back-end. Though not used yet, this will be useful in the future. |
| 4263 | * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about |

| 4277 | redefinitions. |
| 4278 | * data/bison.m4 (b4_percent_define_flag_if): Read |
| 4279 | b4_percent_define_loc(VARIABLE) to report the location of an invalid |
| 4280 | value for VARIABLE. |

| 4297 | defaults): New test case. |
| 4298 | |
| 4299 | 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4300 | |
| 4301 | * src/print.c (lookahead_set, state_default_rule): Remove. |
| 4302 | (print_reductions): Replace state_default_rule invocation with |
| 4303 | equivalent use of yydefact, which was computed in token_actions in |
| 4304 | tables.c. |
| 4305 | (print_results): Don't allocate lookahead_set. |
| 4306 | |
| 4307 | 2007-02-27 Paolo Bonzini <bonzini@gnu.org> |
| 4308 | |

| 4310 | |
| 4311 | 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu> |

| 4313 | Use YYFPRINTF instead of fprintf where appropriate. Reported by |
| 4314 | Sebastien Fricker at |
| 4315 | <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>. |
| 4316 | * THANKS: Add Sebastien Fricker. |
| 4317 | * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement. |
| 4318 | * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must |

| 4333 | Undo my 2007-02-07 change, switching back to the c-strcase module |
| 4334 | introduced in the 2007-02-03 change. Bruno Haible reported that |
| 4335 | the 2007-02-07 change would be dangerous in Turkish if we add a |
| 4336 | language whose name contains "i", since "i" is not lowercase "I" |
| 4337 | in Turkish. |
| 4338 | * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase. |
| 4339 | * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h, |
| 4340 | c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c. |
| 4341 | * m4/.cvsignore: Remove strcase.m4. |
| 4342 | * src/getargs.c: Revert 2007-02-07 change, as follows. |
| 4343 | Include c-strcase.h. |
| 4344 | (language_argmatch): Use c_strcasecmp rather than strcasecmp. |
| 4345 | |
| 4346 | 2007-02-11 Bruno Haible <bruno@clisp.org> |
| 4347 | |
| 4348 | Enable the Java related testsuite tests when the only Java compiler |
| 4349 | found is a gcj < 4.3. Discussed at |
| 4350 | <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>. |
| 4351 | * configure.ac (gt_JAVACOMP): Don't specify a target_version. |
| 4352 | |
| 4353 | 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4354 | |
| 4355 | * data/Makefile.am: Update copyright date. |
| 4356 | * data/push.c (yypull_parse): Report memory exhaustion and return 2 if |
| 4357 | yypstate_new returns NULL. |
| 4358 | (yypstate_new): Return NULL if malloc does. |
| 4359 | * src/reader.c (packgram): Move translation of rule actions from the |
| 4360 | beginning of packgram to... |
| 4361 | (check_and_convert_grammar): ... here right before packgram is invoked |
| 4362 | so it's easier to write more complete comments, and remove redundant |
| 4363 | code. |
| 4364 | |
| 4365 | 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4366 | |
| 4367 | As in semantic actions, make @$ in %initial-action, %destructor, and |
| 4368 | %printer imply %locations. |
| 4369 | * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when |
| 4370 | scanning @$. |
| 4371 | * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting... |
| 4372 | (@$ in %initial-action implies %locations, |
| 4373 | @$ in %destructor implies %locations, |
| 4374 | @$ in %printer implies %locations): ... these new test cases. |
| 4375 | |
| 4376 | 2007-02-07 Paul Eggert <eggert@cs.ucla.edu> |
| 4377 | |
| 4378 | Undo most of the 2007-02-03 change, switching to the strcase module |
| 4379 | now that gnulib strcase has been fixed. |
| 4380 | * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase. |
| 4381 | * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h, |
| 4382 | c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c |
| 4383 | * m4/.cvsignore: Add strcase.m4. |
| 4384 | * src/getargs.c: Revert 2007-02-03 change, as follows. |
| 4385 | Don't include c-strcase.h. |
| 4386 | (language_argmatch): Use strcasecmp rather than c_strcasecmp. |
| 4387 | strcasecmp has "unspecified behavior" outside the POSIX locale, |
| 4388 | but it works fine in practice if at least one argument is ASCII, |
| 4389 | as is the case in Bison. |
| 4390 | |
| 4391 | 2007-02-07 Paolo Bonzini <bonzini@gnu.org> |
| 4392 | |

| 4397 | 2007-02-05 Paolo Bonzini <bonzini@gnu.org> |
| 4398 | |
| 4399 | * data/lalr1.java (Stack): Work around old verifiers that disallow |
| 4400 | access to the private fields of an inner class, from the outer class. |
| 4401 | We can make Stack's fields public because user code doesn't have access |
| 4402 | to the instance of Stack used by parse(). Reported by Paul Eggert. |
| 4403 | |
| 4404 | 2007-02-03 Paul Eggert <eggert@cs.ucla.edu> |
| 4405 | |
| 4406 | * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really |
| 4407 | the right spot for these files? |
| 4408 | * bootstrap.conf (gnulib_modules): Add c-strcase. |
| 4409 | * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c, |
| 4410 | c-strncasecmp.c. |
| 4411 | * src/getargs.c: Include c-strcase.h. |
| 4412 | (language_argmatch): Use c_strcasecmp rather than strcasecmp, |
| 4413 | to avoid unspecified behavior. |
| 4414 | |
| 4415 | 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4416 | |

| 4423 | * data/c++.m4: Adjust default definitions of %define variables. |
| 4424 | * data/java.m4: Adjust default definitions of %define variables. |
| 4425 | * doc/bison.texinfo (Decl Summary): Adjust the %define entry according |
| 4426 | to above behavior. |
| 4427 | * tests/input.at (Boolean %define variables): Test new behavior. |
| 4428 | |
| 4429 | 2007-01-29 Paolo Bonzini <bonzini@gnu.org> |

| 4452 | |
| 4453 | 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4454 | |
| 4455 | Clean up. |
| 4456 | * src/scan-skel.l (at_directive_perform): Add at_directive_argc and |
| 4457 | at_directive_argv arguments so these no longer have to be global |
| 4458 | variables. Also, update the implementation for the following changes. |
| 4459 | (fail_for_at_directive_too_many_args, |
| 4460 | fail_for_at_directive_too_few_args): Add at_directive_name argument. |
| 4461 | (at_directive_name): Remove as at_directive_argv[0] will be used for |
| 4462 | this now. |
| 4463 | (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv |
| 4464 | for the directive name. |
| 4465 | (at_directive_argc, at_directive_argv): Make these local within |
| 4466 | skel_lex instead of global. |
| 4467 | (INITIAL): Update directive start action for above changes. |
| 4468 | (SC_AT_DIRECTIVE_ARG): Rename to... |
| 4469 | (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes. |
| 4470 | (SC_AT_DIRECTIVE_SKIP_WS): Update. |
| 4471 | (scan_skel): Move yylex_destroy to... |
| 4472 | (skel_scanner_free): ... here. |
| 4473 | * tests/skeletons.at (installed skeleton file name): Rename to... |
| 4474 | (installed skeleton file names): ... this. |
| 4475 | |
| 4476 | 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4477 | |
| 4478 | * ChangeLog: For changes in doc/bison.texinfo, consistently reference |
| 4479 | node names: say "Table of Symbols" not "Bison Symbols", and say "Decl |
| 4480 | Summary" not "Directives". |
| 4481 | * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the |
| 4482 | %code entry in "Decl Summary" rather than the one in "Table of Symbols" |
| 4483 | since the former is now the more complete one. |
| 4484 | (Prologue Alternatives): Likewise and do the same for %defines. |
| 4485 | (Table of Symbols): Add summary of %code, add summary of %define, and |
| 4486 | move full %code documentation to... |
| 4487 | (Decl Summary): ... here for consistency with other entries in these |
| 4488 | sections. |
| 4489 | Move %define entry in order to keep this list alphabetized. |
| 4490 | Reword %define entry a little to put less emphasis on the skeleton |
| 4491 | concept, which most users shouldn't have to think about. |
| 4492 | |
| 4493 | 2007-01-26 Paul Eggert <eggert@cs.ucla.edu> |
| 4494 | |
| 4495 | Adjust to recent gnulib changes. |
| 4496 | * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h. |
| 4497 | Add string.h, string_.h, unistd_.h, wchar_.h. |
| 4498 | * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4. |
| 4499 | * src/system.h: Don't include <stpcpy.h>; this is now done by |
| 4500 | <string.h>. |
| 4501 | |
| 4502 | 2007-01-23 Paolo Bonzini <bonzini@gnu.org> |
| 4503 | |
| 4504 | Simplify implementation of unqualified %code, implement macros for |
| 4505 | uniform treatment of boolean %define flags. Document %define. |
| 4506 | * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if, |
| 4507 | b4_percent_code_ifdef): New. |
| 4508 | (b4_percent_code_get): Map unqualified %code to b4_percent_code(). |
| 4509 | * data/c++.m4: Define default value for global_tokens_and_yystype. |
| 4510 | * data/glr.cc: Likewise. |
| 4511 | * data/location.cc: Use b4_percent_define_flag_if. |
| 4512 | |
| 4513 | * doc/bison.texinfo (Decl Summary): Document %define. |
| 4514 | |
| 4515 | * src/parse-gram.y (Unqualified %code): Change muscle name to |
| 4516 | b4_percent_code(). |
| 4517 | (content.opt): Default to empty. |
| 4518 | |
| 4519 | 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4520 | |
| 4521 | Implement support for relative and absolute skeleton file names. |
| 4522 | Discussed starting at |
| 4523 | <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>. |
| 4524 | * doc/bison.texinfo (Decl Summary): Document in %skeleton entry. |
| 4525 | (Bison Options): Document in --skeleton entry. |
| 4526 | * src/output.c (output_skeleton): Use strncpy rather than strcpy since |
| 4527 | full_skeleton can't necessarily hold all of pkgdatadir. |
| 4528 | If the specified skeleton file name contains a `/', don't prepend |
| 4529 | pkgdatadir. |
| 4530 | * src/parse-gram.y (prologue_declaration): If the specified skeleton |
| 4531 | file name contains a `/', prepend the grammar file directory. |
| 4532 | * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at. |
| 4533 | * skeletons.at: New file. |
| 4534 | (relative skeleton file names): New test case. |
| 4535 | (installed skeleton file names): New test case. |
| 4536 | * tests/testsuite.at: Include skeletons.at. |
| 4537 | |
| 4538 | * bootstrap: Update copyright to 2007. |
| 4539 | |
| 4540 | 2007-01-17 Paolo Bonzini <bonzini@gnu.org> |
| 4541 | |
| 4542 | * bootstrap: Remove occurrences of .#bootmp from the files. |
| 4543 | |
| 4544 | 2007-01-17 Akim Demaille <akim@epita.fr> |
| 4545 | |
| 4546 | * doc/bison.texinfo (Calc++ Parser): Don't try to alias |
| 4547 | nonterminals. |
| 4548 | Use per-type %printer. |
| 4549 | |
| 4550 | 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu> |

| 4565 | file. |
| 4566 | Accept "-" standing for stdin. |

| 4574 | 2007-01-15 Paolo Bonzini <bonzini@gnu.org> |
| 4575 | and Joel E. Denny <jdenny@ces.clemson.edu> |
| 4576 | |
| 4577 | Clean up %define and %code implementation in M4 some. Most |
| 4578 | importantly, rename all related macros to be in the b4_percent_define |
| 4579 | and b4_percent_code namespaces. Also, complete support for `.' in |
| 4580 | %define variable names and %code qualifiers. |
| 4581 | * data/bison.m4 (b4_check_user_names): Check for special |
| 4582 | "SKELETON-NAMESPACE(name)" macros instead of using two nested |
| 4583 | m4_foreach loops. |
| 4584 | (b4_get_percent_define, b4_get_percent_code): Rename to... |
| 4585 | (b4_percent_define_get, b4_percent_code_get): ... these. |
| 4586 | Extend documentation with examples. |
| 4587 | For SKELETON-NAMESPACE (as documented for b4_check_user_names), use |
| 4588 | b4_percent_define_skeleton_variables and |
| 4589 | b4_percent_code_skeleton_qualifiers. |
| 4590 | Expect any value for the %define variable `foo' to be stored in the |
| 4591 | macro named `b4_percent_define(foo)'; expect any %code blocks for the |
| 4592 | qualifier `foo' to be stored in a macro named `b4_percent_code(foo)'; |
| 4593 | expect any unqualified %code blocks to be stored in a macro named |
| 4594 | `b4_percent_code_unqualified'. |
| 4595 | Use m4_indir so that %define variable names and %code qualifiers can |
| 4596 | contain `.', which is allowed by the grammar parser. |
| 4597 | (b4_percent_define_default): New macro to set a default value for a |
| 4598 | %define variable. |
| 4599 | (m4_wrap): Update wrapped code, and fix some underquoting. |
| 4600 | (b4_check_user_names_wrap): Update and define outside the m4_wrap. |
| 4601 | Expect grammar uses of %define variables and %code qualifiers to be |
| 4602 | defined in b4_percent_define_user_variables and |
| 4603 | b4_percent_code_user_qualifiers. |
| 4604 | * data/c++.m4: Use b4_percent_define_default rather than |
| 4605 | m4_define_default. Fix some underquoting. Skeleton usage of %define |
| 4606 | variable define_location_comparison now implies skeleton usage of |
| 4607 | %define variable filename_type. |
| 4608 | * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, |
| 4609 | data/push.c, data/yacc.c: Update macro names. |
| 4610 | * src/parse-gram.y (prologue_declaration, grammar_declaration): Update |
| 4611 | muscle names. |

| 4615 | DJGPP specific issues. |
| 4616 | |
| 4617 | * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific |
| 4618 | default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default. |
| 4619 | |
| 4620 | 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4621 | |
| 4622 | * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to |
| 4623 | run parsers in all tests so that Valgrind is invoked during |
| 4624 | maintainer-check-valgrind. |
| 4625 | (Duplicate representation of merged trees): Free all semantic values. |
| 4626 | (Duplicated user destructor for lookahead): Likewise. |
| 4627 | |
| 4628 | 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4629 | |

| 4631 | command-line prefix. |
| 4632 | * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is |
| 4633 | ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't |
| 4634 | miss Valgrind messages. |
| 4635 | (Exploding the Stack Size with Malloc): Likewise. |

| 4641 | <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>. |
| 4642 | * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if. |
| 4643 | Fix some indentation also. |

| 4649 | |
| 4650 | Simplify union and prologue handling, and escape union and lex/parse |
| 4651 | params with digraphs. |
| 4652 | * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default |
| 4653 | values to the empty string since these are no longer guaranteed |
| 4654 | initialized by the front-end. |
| 4655 | * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add |
| 4656 | braces around b4_user_stype since this is no longer done by the |
| 4657 | front-end. |
| 4658 | * src/files.c, src/files.h (pre_prologue_obstack, |
| 4659 | post_prologue_obstack): Remove. |
| 4660 | * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header |
| 4661 | comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped |
| 4662 | with digraphs. This fixes lex params and parse params. |
| 4663 | * src/muscle_tab.h (muscle_pair_list_grow): Update comments. |
| 4664 | * src/output.c (prepare): Remove muscle insertion of the prologues. |
| 4665 | (output): Remove freeing of pre_prologue_obstack and |
| 4666 | post_prologue_obstack. |
| 4667 | * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather |
| 4668 | than prologue_augment for prologue parsing so you don't need prologue |
| 4669 | obstacks. |
| 4670 | (grammar_declaration): For %union RHS, use `braceless' instead of |
| 4671 | "{...}" so that braces are already stripped and code is escaped with |
| 4672 | digraphs. |
| 4673 | * src/reader.c (prologue_augment): Remove. |
| 4674 | (reader): Remove initialization of pre_prologue_obstack and |
| 4675 | post_prologue_obstack. |
| 4676 | * src/reader.h (prologue_augment): Remove. |
| 4677 | |

| 4680 | 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4681 | |
| 4682 | Remove quotes from variables names in %define directives and from |
| 4683 | qualifiers in %code directives, and restrict the characters that are |
| 4684 | allowed in them to M4-friendly ones. For %define, continue to support |
| 4685 | the quoted form as a deprecated feature. Discussed starting at |
| 4686 | <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>. |
| 4687 | * NEWS (2.3a+): Add entry for the change to %define. Update entry for |
| 4688 | %code. |
| 4689 | * doc/bison.texinfo (Prologue Alternatives): Update. |
| 4690 | (Decl Summary): In %defines entry, update mention of `%code requires' |
| 4691 | and `%code provides'. |
| 4692 | (C++ Location Values): Update %define uses. |
| 4693 | (Calc++ Parser Interface): Likewise. |
| 4694 | (Calc++ Parser): Likewise, and update `%code requires' uses. |
| 4695 | (Table of Symbols): Update %code documentation. |
| 4696 | * src/parse-gram.y (prologue_declaration): For %define variables, use |
| 4697 | `variable' instead of `STRING'. |
| 4698 | (grammar_declaration): For %code qualifiers, use `ID' instead of |
| 4699 | `STRING'. |
| 4700 | (variable): New nonterminal that takes an `ID' or a `STRING'. |
| 4701 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code |
| 4702 | and %define uses. |
| 4703 | * tests/calc.at (_AT_DATA_CALC_Y): Update %define use. |
| 4704 | * tests/input.at (Reject unused %code qualifiers): Update %code uses. |
| 4705 | (%define errors): Update %define uses. |
| 4706 | |
| 4707 | 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4708 | |
| 4709 | * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING |
| 4710 | instead of muscle_insert for %define values so that M4-special |
| 4711 | characters are replaced with digraphs. |
| 4712 | * tests/input.at (%define errors): Extend to check weird values. |
| 4713 | |
| 4714 | 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4715 | |
| 4716 | Instead of having skeletons declare all valid %define variables and |
| 4717 | %code qualifiers, provide macros that retrieve the associated values |
| 4718 | and build these lists automatically. Thus Bison will now warn when a |
| 4719 | variable or qualifier is not used by the skeleton in the current |
| 4720 | invocation regardless of whether it might sometimes be used by that |
| 4721 | skeleton in other invocations. Also, move all %define value macros to |
| 4722 | the b4_percent_define_ namespace, and remove the %define "NAME" {CODE} |
| 4723 | form, which is replaced by %code. |
| 4724 | * data/bison.m4 (b4_check_for_unrecognized_names): Rename to... |
| 4725 | (b4_check_user_names): ... this, and change the series of valid name |
| 4726 | arguments to a single list argument for names used in the skeleton |
| 4727 | similar to the existing list argument for names used in the grammar. |
| 4728 | Warn instead of complaining. |
| 4729 | (b4_get_percent_define, b4_get_percent_code): New to retrieve %define |
| 4730 | values and %code code, to format %code code properly, and to build |
| 4731 | lists of all %define variables and %code qualifiers used in the |
| 4732 | skeleton: b4_skeleton_percent_define_variables and |
| 4733 | b4_skeleton_percent_code_qualifiers. |
| 4734 | (b4_check_percent_define_variables, b4_check_percent_code_qualifiers): |
| 4735 | Remove, and... |
| 4736 | (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that |
| 4737 | the skeleton names lists can finish building first. In place of |
| 4738 | b4_used_percent_define_variables and b4_used_percent_code_qualifiers, |
| 4739 | expect the lists b4_user_percent_define_variables and |
| 4740 | b4_user_percent_code_qualifiers. |
| 4741 | * data/c++.m4: Where setting default values for b4_parser_class_name, |
| 4742 | b4_location_type, b4_filename_type, b4_namespace, and |
| 4743 | b4_define_location_comparison, update their names to the |
| 4744 | b4_percent_define_ namespace. |
| 4745 | * data/glr.c: Don't use b4_check_percent_define_variables and |
| 4746 | b4_check_percent_code_qualifiers. Use b4_get_percent_code. |
| 4747 | * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define. |
| 4748 | (b4_parser_class_name, b4_namespace): Define these using |
| 4749 | b4_get_percent_define for parser_class_name and namespace. |
| 4750 | * data/location.cc: Use b4_get_percent_define. |
| 4751 | * data/push.c: Don't use b4_check_percent_define_variables and |
| 4752 | b4_check_percent_code_qualifiers. Use b4_get_percent_code. |
| 4753 | * data/yacc.c: Likewise, and don't call m4_exit in |
| 4754 | b4_use_push_for_pull_if or m4_wrap code will never execute. |
| 4755 | * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list): |
| 4756 | Rename to... |
| 4757 | (muscle_grow_user_name_list): ... this for consistency with the |
| 4758 | terminology used in bison.m4. |
| 4759 | * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to |
| 4760 | %define variable names, and rename muscle used_percent_define_variables |
| 4761 | to user_percent_define_variables. |
| 4762 | (grammar_declaration): Rename muscle used_percent_code_qualifiers to |
| 4763 | user_percent_code_qualifiers. |
| 4764 | (content): Remove. |
| 4765 | (content.opt): Replace content RHS with STRING RHS so %define "NAME" |
| 4766 | {CODE} form is no longer accepted. |
| 4767 | * tests/input.at (Reject bad %code qualifiers): Rename to... |
| 4768 | (Reject unused %code qualifiers): ... this, and update test output. |
| 4769 | (%define error): Update test output. |
| 4770 | |
| 4771 | 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4772 | |
| 4773 | Check for unrecognized %define variables similar to checking for |
| 4774 | unrecognized %code qualifiers. Check for redefined %define variables. |
| 4775 | * data/bison.m4 (b4_check_for_unrecognized_names): New macro that |
| 4776 | generalizes... |
| 4777 | (b4_check_percent_code_qualifiers): ... this, which now wraps it. |
| 4778 | (b4_check_percent_define_variables): New, also wraps it. |
| 4779 | * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define |
| 4780 | variables using b4_check_percent_define_variables. |
| 4781 | * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as |
| 4782 | all those exercised in the test suite and all those listed in the |
| 4783 | `Default values' section of c++.m4. Are there others? |
| 4784 | * data/push.c, data/yacc.c: Declare no valid %define variables. |
| 4785 | * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function, |
| 4786 | similar to muscle_find, but it works even when the muscle stores a |
| 4787 | const value. |
| 4788 | (muscle_grow_used_name_list): New function for constructing the used |
| 4789 | name list muscles that b4_check_for_unrecognized_names requires. |
| 4790 | * src/parse-gram.y (prologue_declaration): Warn if a variable is |
| 4791 | %define'd more than once. Define the b4_used_percent_define_variables |
| 4792 | muscle with muscle_grow_used_name_list. |
| 4793 | (grammar_declaration): Abbreviate %code code with |
| 4794 | muscle_grow_used_name_list. |
| 4795 | * tests/input.at (%define errors): New. |
| 4796 | |
| 4797 | 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4798 | |
| 4799 | Provide warn_at, complain_at, and fatal_at function callbacks to the |
| 4800 | skeletons, and use this for %code qualifier complaints. |
| 4801 | * data/bison.m4 (b4_error_at): New, invoked by... |
| 4802 | (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap |
| 4803 | the skeleton scanner's new @warn_at(...@), @complain_at(...@), and |
| 4804 | @fatal_at(...@) directives. |
| 4805 | (b4_check_percent_code_qualifiers): Rewrite to expect locations for |
| 4806 | qualifiers in b4_used_percent_code_qualifiers and to use |
| 4807 | b4_complain_at. |
| 4808 | * src/location.c, src/location.h (boundary_set_from_string): New global |
| 4809 | function. |
| 4810 | * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global |
| 4811 | function. |
| 4812 | * src/parse-gram.y (grammar_declaration): Add locations for qualifiers |
| 4813 | to b4_used_percent_code_qualifiers. |
| 4814 | * src/scan-skel.l (fail_for_at_directive_too_few_args): New static |
| 4815 | function. |
| 4816 | (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments. |
| 4817 | (lineno): Rename to... |
| 4818 | (out_lineno): ... this so I don't misunderstand it again. |
| 4819 | (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines |
| 4820 | here; these newlines are in the input but not the output file. |
| 4821 | (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to... |
| 4822 | (at_directive_perform): ... this new static function, and add handling |
| 4823 | of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@) |
| 4824 | directives. |
| 4825 | * tests/input.at (Reject bad %code qualifiers): Update test output with |
| 4826 | locations and extend. |
| 4827 | |
| 4828 | * tests/output.at (Output file name: [, Output file name: ]): Remove |
| 4829 | bogus comment about these tests failing. |
| 4830 | |
| 4831 | 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4832 | |
| 4833 | Clean up b4_check_percent_code_qualifiers a little. |
| 4834 | * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers |
| 4835 | in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite |
| 4836 | documentation and add examples. |
| 4837 | * src/parse-gram.y (grammar_declaration): Double-M4-quote those |
| 4838 | qualifiers here. |
| 4839 | |
| 4840 | 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4841 | |
| 4842 | Don't use m4_divert since it makes m4_divert_push and m4_divert_pop |
| 4843 | unreliable -- especially when they're hidden inside another macro. |
| 4844 | * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, |
| 4845 | data/c.m4: Remove m4_divert(-1). |
| 4846 | * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, |
| 4847 | data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with |
| 4848 | m4_divert_push(0) and m4_divert_pop(0). |
| 4849 | * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and |
| 4850 | an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is |
| 4851 | pushed and popped by m4sugar, should be first on the stack. |
| 4852 | |
| 4853 | Provide warn, complain, and fatal function callbacks to the skeletons. |
| 4854 | This provides more flexibility than m4_fatal, improves the error |
| 4855 | message format, and captures messages for translation. Discussed |
| 4856 | starting at |
| 4857 | <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>. |
| 4858 | * data/bison.m4 (b4_error): New, invoked by... |
| 4859 | (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the |
| 4860 | skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@) |
| 4861 | directives. Because these M4 macros might be called when the current |
| 4862 | diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus |
| 4863 | the previous removal of uses of m4_divert, which caused trouble. |
| 4864 | (b4_check_percent_code_qualifiers): Use b4_complain instead of |
| 4865 | m4_fatal to report unrecognized %code qualifiers. |
| 4866 | * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++ |
| 4867 | push parser requests. |
| 4868 | * data/glr.c: Use b4_complain instead of m4_fatal to report |
| 4869 | non-deterministic push parser requests. |
| 4870 | Update @output usage to @output(...@) form. |
| 4871 | * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to |
| 4872 | report missing %defines. Update @output usage to @output(...@) form. |
| 4873 | * data/location.cc, data/push.c, data/yacc.c: Update @output usage to |
| 4874 | @output(...@) form. |
| 4875 | * src/main.c (main): Invoke skel_scanner_free. |
| 4876 | * src/scan-skel.h (skel_scanner_free): Prototype new function. |
| 4877 | * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the |
| 4878 | obstack_for_string from flex-scanner.h. |
| 4879 | (YY_DECL): Use to declare skel_lex static. |
| 4880 | (decode_at_digraphs): Remove; now handled in the new |
| 4881 | SC_AT_DIRECTIVE_ARG start condition. |
| 4882 | (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static |
| 4883 | functions. |
| 4884 | (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc, |
| 4885 | at_directive_argv): New static globals. |
| 4886 | (INITIAL): Use fail_for_invalid_at. |
| 4887 | Don't parse `@output file_name\n' or `@basename(...@)'. Instead, |
| 4888 | recognize the start of a generalized `@directive(...@)' form and |
| 4889 | start... |
| 4890 | (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the |
| 4891 | directive args (using the new obstack_for_string), to decode the |
| 4892 | contained @ diagraphs, and to perform the directive. It recognizes |
| 4893 | @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and |
| 4894 | @output(...@). |
| 4895 | (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by |
| 4896 | SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter, |
| 4897 | `@,'. |
| 4898 | (scan_skel): Initialize obstack_for_string on the first call. |
| 4899 | (skel_scanner_free): New function to free obstack_for_string. |
| 4900 | * tests/input.at (Reject bad %code qualifiers): Update test output. |
| 4901 | |
| 4902 | 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4903 | |
| 4904 | Consolidate the 4 prologue alternative directives (%code, %requires, |
| 4905 | %provides, and %code-top) into a single %code directive with an |
| 4906 | optional qualifier field. Discussed at |
| 4907 | <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>. |
| 4908 | * NEWS (2.3a+): Rewrite the existing entry for the prologue |
| 4909 | alternatives. |
| 4910 | * doc/bison.texinfo (Prologue Alternatives): Update. |
| 4911 | (Decl Summary): Update to %code "requires" and %code "provides". |
| 4912 | (Calc++ Parser): Update to %code "requires". |
| 4913 | (Table of Symbols): Remove entries for %requires, %provides, and |
| 4914 | %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry. |
| 4915 | * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these |
| 4916 | are replaced by b4_percent_code_provides and b4_percent_code_requires, |
| 4917 | which are skeleton-specific. |
| 4918 | (b4_check_percent_code_qualifiers): New. A skeleton can use this to |
| 4919 | declare what %code qualifiers it supports and to complain if any other |
| 4920 | qualifiers were used in the grammar. |
| 4921 | * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires]) |
| 4922 | and b4_user_code([b4_percent_code_provides]) in place of |
| 4923 | b4_user_requires and b4_user_provides. |
| 4924 | * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise. |
| 4925 | Add b4_user_code([b4_percent_code_top]) and |
| 4926 | b4_user_code([b4_percent_code]). |
| 4927 | Invoke b4_check_percent_code_qualifiers. |
| 4928 | * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES, |
| 4929 | PERCENT_REQUIRES): Remove. |
| 4930 | (grammar_declaration): Remove RHS's for %code-top, %provides, and |
| 4931 | %requires. Rewrite the %code RHS as the unqualified form defining the |
| 4932 | muscle b4_percent_code. Add another RHS for the qualified %code form, |
| 4933 | which defines muscles of the form b4_percent_code_QUALIFIER and the |
| 4934 | b4_used_percent_code_qualifiers muscle. |
| 4935 | * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES, |
| 4936 | PERCENT_REQUIRES): Remove. |
| 4937 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use |
| 4938 | %code "requires" and %code "provides". |
| 4939 | * tests/input.at (Reject bad %code qualifiers): New. |
| 4940 | |
| 4941 | 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4942 | |
| 4943 | Use the new code_props interface for destructors and printers. |
| 4944 | * src/symtab.h (symbol, semantic_type): Remove destructor_location and |
| 4945 | printer_location members, and change the type of the destructor and |
| 4946 | printer members to code_props. |
| 4947 | (symbol_destructor_set, symbol_destructor_get, symbol_printer_set, |
| 4948 | symbol_printer_get, semantic_type_destructor_set, |
| 4949 | semantic_type_printer_set, default_tagged_destructor_set, |
| 4950 | default_tagless_destructor_set, default_tagged_printer_set, |
| 4951 | default_tagless_printer_set): Use code_props in arguments and return |
| 4952 | types in place of char const * and location. |
| 4953 | (symbol_destructor_location_get, symbol_printer_location_get): Remove |
| 4954 | since the locations are now contained in the return of |
| 4955 | symbol_destructor_get and symbol_printer_get. |
| 4956 | * src/output.c (symbol_destructors_output, symbol_printers_output): |
| 4957 | Replace with... |
| 4958 | (symbol_code_props_output): ... this to eliminate duplicate code. |
| 4959 | (output_skeleton): Update to use symbol_code_props_output. |
| 4960 | * src/reader.c (symbol_should_be_used): Update use of |
| 4961 | symbol_destructor_get. |
| 4962 | * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set): |
| 4963 | Update uses of the various _destructor_set and _printer_set functions. |
| 4964 | * src/symtab.c: (default_tagged_destructor_location, |
| 4965 | default_tagless_destructor_location, default_tagged_printer_location, |
| 4966 | default_tagless_printer_location): Remove since we... |
| 4967 | (default_tagged_destructor, default_tagless_destructor, |
| 4968 | default_tagged_printer, default_tagless_printer): ... change the type |
| 4969 | of these to code_props. |
| 4970 | (symbol_new, semantic_type_new, symbol_destructor_set, |
| 4971 | semantic_type_destructor_set, symbol_destructor_get, |
| 4972 | symbol_printer_set, semantic_type_printer_set, symbol_printer_get, |
| 4973 | symbol_check_alias_consistency, default_tagged_destructor_set, |
| 4974 | default_tagless_destructor_set, default_tagged_printer_set, |
| 4975 | default_tagless_printer_set): Update. |
| 4976 | (symbol_destructor_location_get, symbol_printer_location_get): Remove. |
| 4977 | (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for |
| 4978 | code_props members. |
| 4979 | (symbol_print): Use SYMBOL_CODE_PRINT. |
| 4980 | |
| 4981 | 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4982 | |
| 4983 | Use the new code_props interface for rule actions. |
| 4984 | * src/symlist.h (symbol_list): Replace action, action_location, and |
| 4985 | used members with a code_props action_props member. |
| 4986 | * src/reader.c (symbol_should_be_used, grammar_rule_check, |
| 4987 | grammar_midrule_action, grammar_current_rule_merge_set, |
| 4988 | grammar_current_rule_symbol_append, packgram): Update. |
| 4989 | * src/scan-code.h (translate_rule_action): Remove, no longer used. |
| 4990 | * src/scan-code.l (handle_action_dollar): Update. |
| 4991 | (translate_rule_action): Remove, no longer used. |
| 4992 | * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update. |
| 4993 | |
| 4994 | 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu> |
| 4995 | |
| 4996 | Use the new code_props interface in parse-gram.y. |
| 4997 | * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt): |
| 4998 | Update all uses of translate_* functions to use the new code_props |
| 4999 | interface and to use gram_scanner_last_string_free and |
| 5000 | code_scanner_last_string_free where possible. |
| 5001 | (grammar_declaration): symbol_list_destructor_set and |
| 5002 | symbol_list_printer_set now perform the translation, so don't do it |
| 5003 | here. Use gram_scanner_last_string_free where possible. |
| 5004 | * src/scan-code.h, src/scan-code.l (translate_symbol_action, |
| 5005 | translate_code): Remove, no longer used. |
| 5006 | * src/symlist.h, src/symlist.c (symbol_list_destructor_set, |
| 5007 | symbol_list_printer_set): Perform code translation here rather than |
| 5008 | depending on the caller to do so. |
| 5009 | |
| 5010 | * src/symlist.h (struct symbol_list): Correct some documentation typos. |
| 5011 | * src/scan-gram.h (gram_last_string): Remove declaration. |
| 5012 | * src/scan-gram.l (last_string): Declare it static. |
| 5013 | |
| 5014 | 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5015 | |
| 5016 | Encapsulate code properties and related functionality for the various |
| 5017 | destructors, printers, and actions into a code_props structure and |
| 5018 | interface. This patch merely implements code_props in scan-code.h and |
| 5019 | scan-code.l. Future patches will rewrite other modules to use it. |
| 5020 | Discussed starting at |
| 5021 | <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>. |
| 5022 | * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to |
| 5023 | consistently initialize const structs that have an empty location |
| 5024 | field. |
| 5025 | * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT |
| 5026 | to ensure consistency. |
| 5027 | * src/scan-code.h (code_props): New structure. |
| 5028 | (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New |
| 5029 | function, macro, and const global variable for initializing a |
| 5030 | code_props with no code. |
| 5031 | (code_props_plain_init, code_props_symbol_action_init, |
| 5032 | code_props_rule_action_init, code_props_translate_code): The rest of |
| 5033 | the new code_props functional interface. Among other things, the init |
| 5034 | functions set the code_props kind field so that |
| 5035 | code_props_translate_code will know whether to behave like |
| 5036 | translate_symbol_action, translate_rule_action, or translate_code. |
| 5037 | These old translate functions must remain until all other modules are |
| 5038 | updated to use the new code_props interface. |
| 5039 | (code_scanner_last_string_free): New function similar to |
| 5040 | gram_scanner_last_string_free. |
| 5041 | (code_scanner_free): Add documentation. |
| 5042 | * src/scan-code.l: Implement the new interface. |
| 5043 | (code_lex): Make it static, add a code_props* argument, and remove the |
| 5044 | rule argument. |
| 5045 | (last_string): New static global similar to the one in scan-gram.l. |
| 5046 | (SC_RULE_ACTION): Update to use the code_props* argument to code_lex |
| 5047 | instead of rule. |
| 5048 | (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the |
| 5049 | code_props since Bison may one day use this information for destructors |
| 5050 | and printers. |
| 5051 | (<*><<EOF>>): Use STRING_FINISH so that last_string is set. |
| 5052 | (handle_action_dollar): Use symbol_list_n_get and set used flag |
| 5053 | directly since symbol_list_n_used_set is removed. |
| 5054 | (translate_action): Add a code_props* argument and remove the rule, |
| 5055 | action, and location arguments. Pass the code_props* on to code_lex. |
| 5056 | (translate_rule_action, translate_symbol_action, translate_code): |
| 5057 | Rewrite as wrappers around the new code_props interface. |
| 5058 | * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since |
| 5059 | it would eventually need to break the encapsulation of code_props. |
| 5060 | |
| 5061 | 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5062 | |
| 5063 | * etc/.cvsignore: New. |
| 5064 | |
| 5065 | 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5066 | |
| 5067 | Add maintainer-push-check to run maintainer-check using push parsing in |
| 5068 | place of pull parsing where available. |
| 5069 | * Makefile.am (maintainer-push-check): New. |
| 5070 | * data/bison.m4 (b4_use_push_for_pull_if): New. |
| 5071 | * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if |
| 5072 | appropriately based on their existing values. |
| 5073 | (yypush_parse): Don't print push-parser-specific diagnostics if push |
| 5074 | parsing is being used in place of pull parsing. |
| 5075 | * data/yacc.c: If push parsing should replace pull parsing, redirect to |
| 5076 | push.c. |
| 5077 | * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment |
| 5078 | variable, and insert b4_use_push_for_pull_flag into muscles. |
| 5079 | * tests/Makefile.am (maintainer-push-check): New. |
| 5080 | |
| 5081 | 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5082 | |
| 5083 | * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse |
| 5084 | (whether successful or failed) so that yypush_parse can be invoked |
| 5085 | again to start a new parse using the same yypstate. |
| 5086 | * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to |
| 5087 | check multiple yypull_parse invocations on the same yypstate. For pull |
| 5088 | mode, extend to check multiple yyparse invocations. |
| 5089 | (Exploding the Stack Size with Alloca): Extend to try with |
| 5090 | %push-pull-parser. |
| 5091 | (Exploding the Stack Size with Malloc): Likewise. |
| 5092 | |
| 5093 | * tests/calc.at (Simple LALR Calculator): Don't specify |
| 5094 | %skeleton "push.c" since %push-pull-parser implies that now. |
| 5095 | * tests/headers.at (export YYLTYPE): Don't check for the push |
| 5096 | declarations. Otherwise, this test case can't be used to see if push |
| 5097 | mode can truly emulate pull mode. |
| 5098 | * tests/input.at (Torturing the Scanner): Likewise. |
| 5099 | * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove. |
| 5100 | (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use |
| 5101 | AT_YACC_IF, which now includes the case of push mode since %skeleton |
| 5102 | need not be used for push mode. This will be more intuitive once |
| 5103 | push.c is renamed to yacc.c. |
| 5104 | |
| 5105 | 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5106 | |
| 5107 | For push mode, convert yyparse from a macro to a function, invoke yylex |
| 5108 | instead of passing a yylexp argument to yypull_parse, and don't |
| 5109 | generate yypull_parse or yyparse unless %push-pull-parser is declared. |
| 5110 | Discussed starting at |
| 5111 | <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>. |
| 5112 | * data/bison.m4 (b4_pull_if): New. |
| 5113 | * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH. |
| 5114 | * data/push.c: Improve M4 quoting a little. |
| 5115 | (b4_generate_macro_args, b4_parenthesize): Remove. |
| 5116 | (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse] |
| 5117 | any time a pull parser is requested. |
| 5118 | Don't #define this as a wrapper around yypull_parse. Instead, when |
| 5119 | both push and pull are requested, make it a function that does that |
| 5120 | same thing. |
| 5121 | (yypull_parse): If there's a b4_prefix, #define this to |
| 5122 | b4_prefix[pull_parse] when both push and pull are requested. |
| 5123 | Don't define this as a function unless both push and pull are |
| 5124 | requested. |
| 5125 | Remove the yylexp argument and hard-code yylex invocation instead. |
| 5126 | * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of |
| 5127 | %push-parser. |
| 5128 | * src/getargs.c (pull_parser): New global initialized to true. |
| 5129 | * getargs.h (pull_parser): extern it. |
| 5130 | * src/output.c (prepare): Insert pull_flag muscle. |
| 5131 | * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token. |
| 5132 | (prologue_declaration): Set both push_parser and pull_parser = true for |
| 5133 | %push-pull-parser. Set push_parser = true and pull_parser = false for |
| 5134 | %push-parser. |
| 5135 | * src/scan-gram.l: Don't accept %push_parser as an alternative to |
| 5136 | %push-parser since there's no backward-compatibility concern here. |
| 5137 | Scan %push-pull-parser. |
| 5138 | * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser |
| 5139 | instead of %push-parser. |
| 5140 | * tests/headers.at (export YYLTYPE): Make yylex static, and don't |
| 5141 | prototype it in the module that calls yyparse. |
| 5142 | * tests/input.at (Torturing the Scanner): Likewise. |
| 5143 | * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well. |
| 5144 | |
| 5145 | 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5146 | |
| 5147 | Update etc/bench.pl. Optimize push mode a little (the yyn change |
| 5148 | deserves most of the credit). |
| 5149 | * Makefile.am (SUBDIRS): Add etc subdirectory. |
| 5150 | * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile. |
| 5151 | * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult, |
| 5152 | yytoken, yyval, and yyloc declarations to... |
| 5153 | (yyparse or yypush_parse): ... here to improve performance. For |
| 5154 | yypush_parse invocations after the first, be sure to assign yyn its old |
| 5155 | value again. |
| 5156 | (yypstate_new): Don't bother initializing the yyresult field since the |
| 5157 | initial value isn't used. |
| 5158 | (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list, |
| 5159 | remove the #define that, in push mode, set it to yyps->NAME. |
| 5160 | * etc/Makefile.am: New. |
| 5161 | * etc/bench.pl: Remove and build it instead from... |
| 5162 | * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke |
| 5163 | "tests/bison" from the build directory by default rather than just |
| 5164 | invoking "bison" from $PATH. |
| 5165 | (calc_grammar): Update push parser code: don't declare yylval globally, |
| 5166 | don't define yyparse_wrapper, and don't #define yyparse. |
| 5167 | (bench_grammar): Update to check all working combinations of yacc.c, |
| 5168 | push.c, impure, pure, pull, and push. |
| 5169 | |
| 5170 | 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5171 | |
| 5172 | For push mode, add pull wrappers around yypush_parse. |
| 5173 | * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros. |
| 5174 | (yypull_parse): New function wrapping yypush_parse. |
| 5175 | (yyparse): New #define wrapping yypull_parse. |
| 5176 | * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser |
| 5177 | is declared. |
| 5178 | * tests/headers.at (export YYLTYPE): Make yylex global. For push mode, |
| 5179 | prototype yylex in the module that calls yyparse, and don't prototype |
| 5180 | yyparse there. Otherwise, the yyparse expansion won't compile. |
| 5181 | * tests/input.at (Torturing the Scanner): Likewise. |
| 5182 | |
| 5183 | 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5184 | |
| 5185 | Enable push parsers to operate in impure mode. Thus, %push-parser no |
| 5186 | longer implies %pure-parser. The point of this change is to move |
| 5187 | towards being able to test the push parser code by running the entire |
| 5188 | test suite as if %push-parser had been declared. |
| 5189 | * data/push.c (yypush_parse): For impure mode, remove the |
| 5190 | yypushed_char, yypushed_val, and yypushed_loc arguments. |
| 5191 | Instead, declare these as local variables initialized to the global |
| 5192 | yychar, yylval, and yylloc. |
| 5193 | For the first yypush_parse invocation only, restore the initial values |
| 5194 | of these global variables when it's time to read a token since they |
| 5195 | have been overwritten. |
| 5196 | * src/parse-gram.y (prologue_declaration): Don't set pure_parser for |
| 5197 | %push-parser. |
| 5198 | * tests/calc.at (Simple LALR(1) Calculator): Always declare |
| 5199 | %pure-parser along with %push-parser since this test case was designed |
| 5200 | for pure push parsers. |
| 5201 | * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused. |
| 5202 | (AT_YACC_OR_PUSH_IF): New. |
| 5203 | (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but |
| 5204 | add a note that it's still wrong for some cases (as it has been for a |
| 5205 | while). |
| 5206 | (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since |
| 5207 | %push-parser no longer implies %pure-parser. |
| 5208 | |
| 5209 | 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5210 | |
| 5211 | Remove some unnecessary differences between the pull parser code and |
| 5212 | the push parser code. This patch enables yynerrs in push mode. |
| 5213 | * data/push.c: Reformat M4 a little. |
| 5214 | (b4_yyerror_range): Remove and convert all uses to just yyerror_range. |
| 5215 | (b4_declare_scanner_communication_variables): Don't omit yynerrs just |
| 5216 | because push mode is on. Instead, if pure mode is on, move yynerrs |
| 5217 | to... |
| 5218 | (b4_declare_parser_state_variables): ... here. |
| 5219 | (yynerrs, yyerror_range): For push mode, #define each NAME in this list |
| 5220 | to yyps->NAME so it can be used in yypush_parse. |
| 5221 | (yypush_parse): Don't omit uses of yynerrs in push mode. |
| 5222 | |
| 5223 | 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5224 | |
| 5225 | Fix bug such that the first pushed token's value and location are |
| 5226 | sometimes overwritten (sometimes by %initial-action) before being used. |
| 5227 | * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and |
| 5228 | yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity. |
| 5229 | For the first yypush_parse invocation, initialize yychar to YYEMPTY to |
| 5230 | more closely mimic the pull parser logic. |
| 5231 | Don't copy the pushed token to yychar, yylval, and yylloc until it's |
| 5232 | time to read a token, which is after any initialization of yylval and |
| 5233 | yylloc. |
| 5234 | (gottoken): Rename label to... |
| 5235 | (yyread_pushed_token): ... for clarity and to avoid infringing on the |
| 5236 | user namespace. |
| 5237 | |
| 5238 | 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5239 | |
| 5240 | Rearrange initialization of the parser state variables so that the |
| 5241 | skeleton doesn't have to have a copy for pull mode and another for push |
| 5242 | mode. This patch also fixes at least a bug such that yylloc was not |
| 5243 | initialized (with b4_location_initial_line and |
| 5244 | b4_location_initial_column) upon calling yypush_parse. However, that |
| 5245 | initialization now overwrites the first token's location; |
| 5246 | %initial-action assigning @$ already did the same thing, and both bugs |
| 5247 | will be fixed in a later patch. |
| 5248 | * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa. |
| 5249 | (b4_declare_parser_state_variables): Remove initialization of yytoken, |
| 5250 | yyss, yyvs, yyls, and yystacksize. |
| 5251 | (yypstate_new): Remove initialization of some yypstate fields: yystate, |
| 5252 | yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and |
| 5253 | yylsp. |
| 5254 | (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to |
| 5255 | yyps->NAME so it can be used in yypush_parse. |
| 5256 | (yyparse or yypush_parse): For yypush_parse, don't print the |
| 5257 | "Starting parse" diagnostic for invocations after the first. |
| 5258 | Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for |
| 5259 | yypush_parse, only do it for the first invocation. |
| 5260 | Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc |
| 5261 | initialization to occur in yypush_parse but only on the first |
| 5262 | invocation. |
| 5263 | |
| 5264 | 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5265 | |
| 5266 | * data/push.c: Add CPP guards around push parser declarations in both |
| 5267 | the header and the code file. |
| 5268 | In the code file, move the push parser declarations to the same place |
| 5269 | they appear in the header file. |
| 5270 | Clean up the M4 some, especially the inconsistent underquoting in |
| 5271 | some b4_c_function_def and b4_c_function_decl uses. |
| 5272 | |
| 5273 | 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5274 | |
| 5275 | Encapsulate the push parser state variables into an M4 macro so the |
| 5276 | push skeleton doesn't have to list them again for pull mode's yyparse. |
| 5277 | For push mode, remove yypush_parse's local equivalents of these |
| 5278 | variables to eliminate unnecessary copying between the two sets at |
| 5279 | run-time. This patch also fixes at least a bug related to multiple |
| 5280 | %initial-action invocations in push mode. |
| 5281 | * data/push.c (b4_declare_parser_variables): Rename to... |
| 5282 | (b4_declare_scanner_communication_variables): ... this for clarity and |
| 5283 | update both uses. |
| 5284 | (b4_declare_yyparse_variables): Remove and move its contents to the one |
| 5285 | spot where it was invoked. |
| 5286 | (b4_declare_parser_state_variables): New macro containing the parser |
| 5287 | state variables required by push mode. |
| 5288 | (struct yypstate): Replace all fields but yynew with |
| 5289 | b4_declare_parser_state_variables. |
| 5290 | (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs, |
| 5291 | yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define |
| 5292 | each NAME in this list to yyps->NAME so it can be used in yypush_parse. |
| 5293 | (yyparse or yypush_parse): For yyparse in pull mode, replace local |
| 5294 | parser state variable declarations with |
| 5295 | b4_declare_parser_state_variables. |
| 5296 | Don't initialize parser state variables when calling yypush_parse since |
| 5297 | yypstate_new already does that. |
| 5298 | Invoke the user's initial action only upon the first yypush_parse |
| 5299 | invocation. |
| 5300 | Remove all code that copies between the local parser state variables |
| 5301 | and the yypstate. |
| 5302 | |
| 5303 | 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5304 | |
| 5305 | * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to |
| 5306 | prevent a name collision in a future patch where these names will |
| 5307 | sometimes be #define'd. |
| 5308 | (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field |
| 5309 | since it no longer has the same name as the existing argument. |
| 5310 | (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE. |
| 5311 | |
| 5312 | 2006-12-19 Paolo Bonzini <bonzini@gnu.org> |
| 5313 | and Joel E. Denny <jdenny@ces.clemson.edu> |
| 5314 | |
| 5315 | * doc/bison.texinfo (Decl Summary): In the %language entry, mention |
| 5316 | that the argument is case-insensitive, and there's no `=' here. |
| 5317 | For the %skeleton entry, mention that %language is better. |
| 5318 | (Bison Options): Likewise for --language and --skeleton. Move the |
| 5319 | --skeleton entry so that the `Tuning the parser' section is sorted |
| 5320 | alphabetically on long options. |
| 5321 | (C++ Bison Interface): Don't use the word skeleton. Don't explain the |
| 5322 | %language directive in detail here; cross-reference the %language |
| 5323 | documentation instead. |
| 5324 | (Calc++ Parser): Use `%require "@value{VERSION}"' rather than |
| 5325 | `%require "2.3b"' so that the example is always up-to-date. |
| 5326 | (Table of Symbols): Add entries for %language and %skeleton. |
| 5327 | * examples/extexi (normalize): Instead of replacing every %require |
| 5328 | argument with the current Bison version, just substitute for |
| 5329 | `@value{VERSION}'. This guarantees that we're testing what actually |
| 5330 | appears in the documentation. |
| 5331 | * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)' |
| 5332 | rather than `@VERSION@'. |
| 5333 | |
| 5334 | 2006-12-18 Paul Eggert <eggert@cs.ucla.edu> |
| 5335 | |
| 5336 | * NEWS: Reword the %language news a bit, and put it earlier. |
| 5337 | |
| 5338 | * src/getargs.c (skeleton_arg): Last arg is now location const *. |
| 5339 | Rewrite to simplify the logic. |
| 5340 | (language_argmatch): Likewise. |
| 5341 | (program_name): We now own this var. |
| 5342 | * src/getargs.h (struct bison_language): Use char[] rather than |
| 5343 | const char *. |
| 5344 | |
| 5345 | * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim |
| 5346 | Java is supported. |
| 5347 | * src/complain.c (program_name): Remove decl; no longer needed. |
| 5348 | * src/main.c (program_name): Remove; now belongs to getargs. |
| 5349 | |
| 5350 | 2006-12-18 Paolo Bonzini <bonzini@gnu.org> |
| 5351 | |
| 5352 | * NEWS: Document %language. |
| 5353 | |
| 5354 | * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4. |
| 5355 | |
| 5356 | * data/c-skel.m4, data/c++-skel.m4: New files. |
| 5357 | * data/glr.c: Complain on push parsers. |
| 5358 | |
| 5359 | * doc/bison.texinfo (C++ Parser Interface): Prefer %language |
| 5360 | over %skeleton. |
| 5361 | (Decl Summary): Document %language and %skeleton. |
| 5362 | (Command line): Document -L. |
| 5363 | |
| 5364 | * examples/extexi: Rewrite %require directive. |
| 5365 | * examples/calc++/Makefile.am: Pass VERSION to extexi. |
| 5366 | |
| 5367 | * src/files.c (compute_exts_from_gc): Look in language structure |
| 5368 | for .y extension. |
| 5369 | (compute_file_name_parts): Check whether .tab should be added. |
| 5370 | * src/getargs.c (valid_languages, skeleton_prio, language_prio): |
| 5371 | (language, skeleton_arg, language_argmatch): New. |
| 5372 | (long_options): Add --language. |
| 5373 | (getargs): Use skeleton_arg, add -L/--language. |
| 5374 | * src/getargs.h: Include location.h. |
| 5375 | (struct bison_language, language, skeleton_arg, language_argmatch): New. |
| 5376 | * src/output.c (prepare): Pick default skeleton from struct language. |
| 5377 | Don't dispatch C skeletons here. |
| 5378 | * src/parse-gram.y (PERCENT_LANGUAGE): New. |
| 5379 | (prologue_declaration): Add "%language" rule, use skeleton_arg. |
| 5380 | * src/scan-gram.l ("%language"): New rule. |
| 5381 | |
| 5382 | * tests/calc.at: Test %skeleton and %language. |
| 5383 | * tests/local.at (AT_SKEL_CC_IF): Look for %language. |
| 5384 | (AT_GLR_IF): Look for %skeleton "glr.cc". |
| 5385 | (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite. |
| 5386 | (AT_YACC_IF): Reject %language. |
| 5387 | |
| 5388 | 2006-12-18 Paul Eggert <eggert@cs.ucla.edu> |
| 5389 | |
| 5390 | * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type', |
| 5391 | since it wasn't used; only the typedef name 'semantic_type' is needed. |
| 5392 | Also, omit trailing white space. |
| 5393 | |
| 5394 | * bootstrap: Sync from coreutils. |
| 5395 | (gnulib_extra_files): Add build-aux/announce.gen. |
| 5396 | (slurp): Adjust .gitignore files like .cvsignore files. |
| 5397 | * build-aux/announce-gen: Remove from CVS, since bootstrap |
| 5398 | now creates this. |
| 5399 | |
| 5400 | 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5401 | |
| 5402 | Make %push-parser imply %pure-parser. This fixes several bugs; see |
| 5403 | <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>. |
| 5404 | * src/parse-gram.y (prologue_declaration): For %push-parser, also set |
| 5405 | pure_parser = true. |
| 5406 | * data/push.c: Don't bother testing b4_push_if when deciding whether |
| 5407 | to expand b4_declare_parser_variables globally. |
| 5408 | (yypush_parse): Likewise in here. |
| 5409 | |
| 5410 | * data/push.c (yypush_parse): Add b4_parse_param to arguments. |
| 5411 | (yy_reduce_print): Reformat M4 for readability. |
| 5412 | |
| 5413 | 2006-12-15 Bob Rossi <bob@brasko.net> |
| 5414 | and Joel Denny <jdenny@ces.clemson.edu> |
| 5415 | |
| 5416 | * data/push.c (yypstate): Add typedef, and update all uses of |
| 5417 | struct yypstate to just yypstate. |
| 5418 | * tests/calc.at (_AT_DATA_CALC_Y): Update here as well. |
| 5419 | |
| 5420 | 2006-12-14 Bob Rossi <bob@brasko.net> |
| 5421 | |
| 5422 | * data/push.c (yypush_parse): Declare prototype regardless of |
| 5423 | %locations option. |
| 5424 | |
| 5425 | 2006-12-14 Bob Rossi <bob@brasko.net> |
| 5426 | |
| 5427 | * data/push.c (yyparse): Remove the prototype and the #define when in |
| 5428 | push-parser mode. |
| 5429 | |
| 5430 | 2006-12-13 Bob Rossi <bob@brasko.net> |
| 5431 | |
| 5432 | * data/push.c (yypstate_init): Rename to... |
| 5433 | (yypstate_new): ... this and use b4_c_function_def. |
| 5434 | (yypstate_delete): New. |
| 5435 | (yypush_parse): Change parameters yynval and yynlloc to be const. |
| 5436 | * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and |
| 5437 | yypstate_delete functions. |
| 5438 | |
| 5439 | 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5440 | |
| 5441 | * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our |
| 5442 | strange test case titles. Reported by Bob Rossi. |
| 5443 | |
| 5444 | 2006-12-13 Paul Eggert <eggert@cs.ucla.edu> |
| 5445 | |
| 5446 | * TODO: Add pointer to Sylvain Schmitz's work on static detection |
| 5447 | of potential ambiguities in GLR grammers. |
| 5448 | |
| 5449 | 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5450 | |
| 5451 | * tests/testsuite.at (AT_CHECK): When checking if $1 starts with |
| 5452 | `bison ', use m4_index instead of m4_substr since chopping up a string |
| 5453 | containing M4-special characters causes problems here. |
| 5454 | |
| 5455 | Fix a couple of bugs related to special characters in user-specified |
| 5456 | file names, and make it easier for skeletons to compute output file |
| 5457 | names with the same file name prefix as Bison-computed output file |
| 5458 | names. |
| 5459 | * data/glr.cc, data/push.c, data/yacc.c: In @output, use |
| 5460 | b4_parser_file_name and b4_spec_defines_file instead of |
| 5461 | @output_parser_name@ and @output_header_name@, which are now redundant. |
| 5462 | * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use |
| 5463 | b4_parser_file_name, b4_spec_defines_file, and the new |
| 5464 | @basename(FILENAME@) instead of @output_parser_name@ and |
| 5465 | @output_header_name@, which inappropriately escaped the file names as |
| 5466 | C string literals. |
| 5467 | * src/files.c (all_but_ext): Remove static qualifier. |
| 5468 | (compute_output_file_names): Move `free (all_but_ext)' to... |
| 5469 | (output_file_names_free): ... here since all_but_ext is needed later. |
| 5470 | * src/files.h (all_but_ext): Extern. |
| 5471 | * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does |
| 5472 | exactly what MUSCLE_INSERT_STRING used to do. |
| 5473 | (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special |
| 5474 | characters are escaped properly. |
| 5475 | * src/output.c (prepare): Define muscle file_name_all_but_ext as |
| 5476 | all_but_ext. |
| 5477 | For pkgdatadir muscle, maintain previous functionality by using |
| 5478 | MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem |
| 5479 | is that b4_pkgdatadir is used inside m4_include in the skeletons, so |
| 5480 | digraphs would never be expanded. Hopefully no one has M4-special |
| 5481 | characters in his Bison installation path. |
| 5482 | * src/scan-skel.l: Don't parse @output_header_name@ and |
| 5483 | @output_parser_name@ anymore since they're now redundant. |
| 5484 | In @output, use decode_at_digraphs. |
| 5485 | Parse a new @basename command that invokes last_component. |
| 5486 | (decode_at_digraphs): New. |
| 5487 | (BASE_QPUTS): Remove unused. |
| 5488 | * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro. |
| 5489 | (Output file name): New tests. |
| 5490 | |
| 5491 | 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5492 | |
| 5493 | Warn about output files that are generated by the skeletons and that |
| 5494 | conflict with other output files. |
| 5495 | * data/glr.c: Don't generate the header file here when glr.cc does. |
| 5496 | * src/files.c (file_names, file_names_count): New static globals. |
| 5497 | (compute_output_file_names): Invoke output_file_name_check for files |
| 5498 | not generated by the skeletons and remove existing checks. |
| 5499 | (output_file_name_check): New function that warns about conflicting |
| 5500 | output file names. |
| 5501 | (output_file_names_free): Free file_names. |
| 5502 | * src/files.h (output_file_name_check): Declare. |

| 5518 | (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps. |
| 5519 | (yypush_parse): Rename yypvars argument to yyps and remove redundant |
| 5520 | local pv. |
| 5521 | (yypstate_init, yypush_parse): Declare in Bison-generated header file. |

| 5525 | and Joel Denny <jdenny@ces.clemson.edu> |
| 5526 | |
| 5527 | * data/push.c (yypvarsinit): Change return type from void* to struct |
| 5528 | yypvars*. No longer cast to void* on return. |
| 5529 | (struct yypvars): Remove yylen since it need not be remembered between |
| 5530 | yypushparse invocations. |
| 5531 | (yypushparse): Don't copy between yylen and pv->yylen. |
| 5532 | |
| 5533 | 2006-12-05 Bob Rossi <bob@brasko.net> |
| 5534 | |
| 5535 | * data/push.c (yychar_set, yylval_set, yylloc_set): Delete. |

| 5541 | push or pure mode. |
| 5542 | (yypushparse): Add b4_declare_parser_variables. |
| 5543 | Init new local variables, and remove init code for removed |
| 5544 | yypvars variables. |
| 5545 | (yyparse): Delete. |
| 5546 | * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode |
| 5547 | and yyparse for other modes. |

| 5587 | 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu> |

| 5635 | later. Reported by Paul Eggert in |
| 5636 | <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>. |
| 5637 | * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9. |
| 5638 | * src/scan-code.l (translate_action): Don't bother invoking |
| 5639 | yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer. |
| 5640 | (code_scanner_free): Instead of invoking |
| 5641 | yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy, |
| 5642 | which frees more. |
| 5643 | * src/scan-gram.l (gram_scanner_free): Likewise. |
| 5644 | * src/scan-skel.l (scan_skel): Likewise. |

| 5648 | * src/files.c (tr): Change return type to void. |
| 5649 | * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow |
| 5650 | has been called previously for the same key. |
| 5651 | (muscle_find): Return storage instead of value so that |
| 5652 | --enable-gcc-warnings doesn't produce warnings that the return discards |
| 5653 | const. aver that the value and storage are the same since storage |
| 5654 | could potentially be NULL when value is not. |
| 5655 | * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the |
| 5656 | same as 0. |
| 5657 | |
| 5658 | 2006-11-08 Paul Eggert <eggert@cs.ucla.edu> |

| 5660 | * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing |
| 5661 | the earlier change today), m4/intl.m4, m4/intldir.m4. This gives |
| 5662 | us a slightly cleaner distribution, and also works. |
| 5663 | * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent |
| 5664 | gnulib changes. |
| 5665 | |
| 5666 | 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5667 | and Paul Eggert <eggert@cs.ucla.edu> |
| 5668 | |
| 5669 | Don't let Bison leak memory except when it complains. |

| 5671 | (spec_defines_file, dir_prefix): Now char *, not const char *, |
| 5672 | since they are freed. |
| 5673 | * src/files.c: Likewise. |
| 5674 | (all_but_ext, all_but_tab_ext, src_extension, header_extension): |
| 5675 | Likewise. |

| 5677 | (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary |
| 5678 | values. |
| 5679 | (compute_file_name_parts, compute_output_file_names): Don't store |
| 5680 | read-only data in variables that will be freed. |

| 5682 | src_extension, and header_extension. |
| 5683 | (output_file_names_free): New public function to free |
| 5684 | spec_verbose_file, spec_graph_file, spec_defines_file, |
| 5685 | parser_file_name, and dir_prefix. |
| 5686 | * src/getargs.c (getargs): Don't store read-only data in variables that |
| 5687 | will be freed. |
| 5688 | * src/main.c (main): Invoke output_file_names_free, code_scanner_free |
| 5689 | (which previously existed but was unused), and quotearg_free. |
| 5690 | * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'. |
| 5691 | * src/muscle_tab.c: Likewise. |
| 5692 | (muscle_entry): Make the value char const *, |
| 5693 | and add a new storage member that is char * and can be freed. |
| 5694 | (muscle_entry_free): New private function. |
| 5695 | (muscle_init): Use it instead of free. |
| 5696 | (muscle_insert, muscle_grow): Update and use new storage member. |
| 5697 | (muscle_code_grow): Free the string passed to muscle_grow |
| 5698 | since it's not needed anymore. |
| 5699 | * src/parse-gram.y (%union): Make `chars' member a `char const *', and |
| 5700 | add a new `char *code' member. |
| 5701 | ("{...}"): Declare semantic type as code. |
| 5702 | * src/scan-code.h (translate_rule_action): |
| 5703 | (translate_symbol_action, translate_code, translate_action): Return |
| 5704 | `char const *' rather than `char *' since external code should not free |
| 5705 | these strings. |
| 5706 | * src/scan-code.l: Likewise. |
| 5707 | * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE, |
| 5708 | which is "{...}" in the parser. |
| 5709 | * tests/Makefile.am (maintainer-check-valgrind): Set |
| 5710 | VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking |
| 5711 | Valgrind. |
| 5712 | * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't |
| 5713 | complain. |
| 5714 | * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and |
| 5715 | expecting a non-zero exit status sets --leak-check=summary and |
| 5716 | --show-reachable=no for Valgrind. Bison unabashedly leaks memory in |
| 5717 | this case, and we don't want to hear about it. |
| 5718 | |
| 5719 | 2006-11-08 Paul Eggert <eggert@cs.ucla.edu> |
| 5720 | |
| 5721 | * bootstrap (runtime-po/Makevars): Derive from po/Makevars |
| 5722 | instead of from the template, to simplify configuration a bit. |
| 5723 | * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4 |
| 5724 | and m4/wint_t.m4, as they are needed with the latest gnulib. |
| 5725 | |

| 5743 | 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5744 | |
| 5745 | Finish implementing --warnings=error, which should not be implied by |

| 5747 | subarguments). |
| 5748 | * src/complain.c (set_warning_issued): New function to report that |
| 5749 | warnings are being treated as errors and to record an error if so. |

| 5753 | "error - warnings are errors" does not appear above "all - all of the |
| 5754 | above". |
| 5755 | (getargs): For -W and --warnings without subarguments, don't let |
| 5756 | FLAGS_ARGMATCH set warnings_error in warnings_flag. |
| 5757 | * src/getargs.h (enum warnings): Unset warnings_error in warnings_all. |
| 5758 | |
| 5759 | 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu> |

| 5763 | |
| 5764 | 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5765 | |
| 5766 | * data/push.c, data/yacc.c: Make sure there's a newline at the end of |
| 5767 | the parser header file so that gcc doesn't warn. |
| 5768 | |
| 5769 | 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu> |

| 5823 | (symbol_is_dummy): Check for both forms of the name. |
| 5824 | * src/reader.c (packgram): Remove the `$' from each midrule symbol |
| 5825 | name for which the midrule value is referenced in any action. |
| 5826 | * tests/actions.at (Default %printer and %destructor for mid-rule |
| 5827 | values): New test. |
| 5828 | * tests/regression.at (Rule Line Numbers, Web2c Report): Update output |
| 5829 | for change to dummy symbol names. |
| 5830 | |
| 5831 | 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5832 | |
| 5833 | Warn about unset midrule $$ if the corresponding $n is used. |
| 5834 | * src/reader.c (symbol_should_be_used): Check midrule parent rule for |
| 5835 | $n usage. |
| 5836 | (packgram): Before invoking grammar_rule_check on any rule, make sure |
| 5837 | all actions have already been scanned in order to set `used' flags. |
| 5838 | Otherwise, checking that a midrule's $$ is set will not always work |
| 5839 | properly because the midrule check must forward-reference the midrule's |
| 5840 | parent rule. |
| 5841 | * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new |
| 5842 | warning. |
| 5843 | |

| 5848 | Bison manual. |
| 5849 | * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add |

| 5851 | to show how these directives may be viewed as code labels. |
| 5852 | |
| 5853 | 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu> |
| 5854 | |
| 5855 | Similar to the recently removed %before-header, add %code-top as the |
| 5856 | alternative to the pre-prologue. Mentioned at |
| 5857 | <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>. |
| 5858 | Also, let the prologue alternatives appear in the grammar section. |
| 5859 | * src/parse-gram.y (PERCENT_CODE_TOP): New token. |
| 5860 | (prologue_declaration): Move the existing prologue alternatives to... |
| 5861 | (grammar_declaration): ... here and add %code-top. |

| 5866 | * doc/bison.texinfo (Prologue): Move discussion of prologue |
| 5867 | alternatives to... |

| 5869 | all 4 directives in detail. |
| 5870 | (Table of Symbols): Clean up discussion of prologue alternatives and |
| 5871 | add %code-top. |

| 5912 | is version controlled with git, rather than CVS. |
| 5913 | * bootstrap (CVS_only_file): Test for the existence of README-cvs, |

| 5922 | |
| 5923 | Fix testsuite for ./configure --enable-gcc-warnings: |
| 5924 | * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare. |
| 5925 | Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in |
| 5926 | __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at. |
| 5927 | * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort. |

| 5965 | |
| 5966 | 2006-10-11 Paul Eggert <eggert@cs.ucla.edu> |
| 5967 | |
| 5968 | * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell |
| 5969 | variable was sometimes used without being initialized. This |
| 5970 | messed up the installation of the INSTALL file in some cases. |
| 5971 | |
| 5972 | 2006-10-09 Paul Eggert <eggert@cs.ucla.edu> |
| 5973 | |
| 5974 | * bootstrap (usage, main program, symlink_to_gnulib): Add option |
| 5975 | --copy. Inspired by a suggestion from Bruno Haible. |
| 5976 | |
| 5977 | 2006-10-03 Jim Meyering <jim@meyering.net> |
| 5978 | |
| 5979 | * bootstrap: Undo last change to this file, since now gnulib-tool |
| 5980 | sticks with the automake default in generating dependencies. |

| 5983 | |

| 5988 | |
| 5989 | * data/glr.c: Don't include <stdarg.h>; not used. |

| 6008 | * src/print_graph.c: Include graphviz.h rather than vcg.h. |
| 6009 | (static_graph, fgraph): Remove. All uses changed to pass |
| 6010 | arguments instead of sharing a static var. |
| 6011 | (print_core, print_actions, print_state, print_graph): |
| 6012 | Output graphviz format rather than VCG format. |

| 6059 | <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html> |
| 6060 | and try to make such failures easier to catch in the future. |
| 6061 | * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg; |
| 6062 | that's now the caller's responsibility. |
| 6063 | (yyprocessOneStack, yyrecoverSyntaxError, yyparse): |
| 6064 | Set yychar = YYEOF if it's negative. |

| 6075 | Fix problems with translating English-language diagnostics. |
| 6076 | * bootstrap: Fix bug introduced in recent bootstrap changes, with |

| 6090 | when all of the sources in a directory come from gnulib. |
| 6091 | * bootstrap (gnulib_tool): Remove the "no-dependencies" automake |
| 6092 | option that gnulib-tool adds to what becomes our lib/gnulib.mk. |

| 6094 | 2006-09-23 Jim Meyering <jim@meyering.net> |
| 6095 | |

| 6125 | |
| 6126 | 2006-09-18 Paul Eggert <eggert@cs.ucla.edu> |
| 6127 | |
| 6128 | * bootstrap (symlink_to_gnulib): New function. |

| 6130 | to copies-of-gnulib. |
| 6131 | (cp_mark_as_generated, slurp, gnulib_files): |
| 6132 | Avoid making a copy if it's the same as the old version. |
| 6133 | (gnulib_files): Add support for this variable (used by Bison). |
| 6134 | |
| 6135 | 2006-09-20 Paul Eggert <eggert@cs.ucla.edu> |
| 6136 | |
| 6137 | * src/getargs.c (usage): Rework to use conventions similar to |
| 6138 | coreutils, to make translation a bit easier and the code a bit |
| 6139 | smaller. Problem reported by Tim Van Holder. |
| 6140 | |
| 6141 | 2006-09-15 Paul Eggert <eggert@cs.ucla.edu> |
| 6142 | |
| 6143 | Use some of gnulib's new modules, taken from coreutils. |
| 6144 | |

| 6152 | (gl_EARLY): Add. |
| 6153 | (AM_STDBOOL_H): Remove; gl_INIT now dows this. |
| 6154 | (gl_INIT): Add |
| 6155 | (GNULIB_AUTOCONF_SNIPPET): Remove. |

| 6169 | gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4. |
| 6170 | * src/Makefile.am (DEFS): Remove, since configmake does this for us. |
| 6171 | (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us. |
| 6172 | * src/system.h: Include inttypes.h unconditionally, now that we |
| 6173 | use the inttypes module. Don't bother to include stdint.h, since |
| 6174 | inttypes.h now does that for us. |
| 6175 | (LOCALEDIR): Remove, now that we use the configmake module. |
| 6176 | * src/getargs.c: Include configmake.h. |
| 6177 | * src/main.c: Likewise. |

| 6183 | Port to GCC 2.95. First two problems reported by Michael Deutschmann in |
| 6184 | <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>. |
| 6185 | |
| 6186 | * src/parse-gram.y (symbol_declaration): Don't put statements |
| 6187 | before declarations; it's not portable to C89. |
| 6188 | * src/scan-code.l (handle_action_at): Likewise. |
| 6189 | |
| 6190 | * src/scan-code.l: Always initialize braces_level; the old code |
| 6191 | left it uninitialized and therefore had undefined behavior. |
| 6192 | |
| 6193 | Don't attempt to redefine 'assert', since it runs afoul of |
| 6194 | systems where standard headers (mistakenly) include <assert.h>. |
| 6195 | Instead, define and use our own alternative, called 'aver'. |
| 6196 | * src/reader.c: Don't include assert.h, since we no longer |
| 6197 | use assert. |
| 6198 | * src/scan-code.l: Likewise. |
| 6199 | * src/system.h (assert): Remove, replacing with.... |
| 6200 | (aver): New function, taking a bool arg. All uses changed. |
| 6201 | * src/tables.c (pack_vector): Ensure that aver arg is bool, |
| 6202 | not merely an integer. |
| 6203 | |
| 6204 | 2006-09-15 Bob Rossi <bob@brasko.net> |
| 6205 | |
| 6206 | Add support for push parsing. Based on the original work of |
| 6207 | Odd Arild Olsen <oao@fibula.no>. |
| 6208 | * data/Makefile.am (dist_pkgdata_DATA): Add push.c. |
| 6209 | * data/c.m4 (YYPUSH): New. |
| 6210 | (b4_push_if): New macro. Use it instead of #ifdef YYPUSH. |
| 6211 | * data/push.c: New file. |
| 6212 | * src/getargs.c (push_parser): New var. |
| 6213 | * src/getargs.h (push_parser): New declaration. |
| 6214 | * src/output.c (prepare): Add macro insertion of `push_flag'. |
| 6215 | * src/parse-gram.y (PERCENT_PUSH_PARSER): New token. |
| 6216 | (prologue_declaration): Parse %push-parser. |
| 6217 | * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token. |
| 6218 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to |
| 6219 | list of removed lines from the traces observed. |
| 6220 | (AT_CHECK_CALC_LALR): Added push parser tests. |
| 6221 | |
| 6222 | 2006-09-13 Paul Eggert <eggert@cs.ucla.edu> |
| 6223 | |
| 6224 | * NEWS: Version 2.3a. |
| 6225 | * configure.ac (AC_INIT): Likewise. |
| 6226 | |
| 6227 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove |
| 6228 | "#define YYSTYPE int" that caused "make maintainer-check" to fail |
| 6229 | due to header ordering dependencies. I don't know why the #define |
| 6230 | was there. |
| 6231 | |
| 6232 | Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero |
| 6233 | runtime cost when YYDEBUG is not defined, and so that some tests |
| 6234 | that used to fail now work. Problem and initial suggestion by |
| 6235 | Paolo Bonzini. |
| 6236 | * data/c++.m4 (b4_parse_param_cons): Omit leading ','. |
| 6237 | * data/glr.cc (b4_parser_class_name): |
| 6238 | Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_. |
| 6239 | (debug_level, set_debug_level): Affect yydebug_, not ::yydebug. |
| 6240 | (yydebug_) [YYDEBUG]: New member. |
| 6241 | (yycdebug_): Now defined only if YYDEBUG. |
| 6242 | * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG. |
| 6243 | (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_. |
| 6244 | (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only |
| 6245 | if YYYDEBUG. |
| 6246 | (debug_stream, set_debug_stream, debug_level, set_debug_level): |
| 6247 | Define only if YYDEBUG. |
| 6248 | * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to |
| 6249 | set_debug_level. |
| 6250 | * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise. |
| 6251 | * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to |
| 6252 | AT_CHECK_CALC_GLR_CC that are working now. |
| 6253 | |
| 6254 | 2006-09-12 Paul Eggert <eggert@cs.ucla.edu> |
| 6255 | |
| 6256 | * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove. |
| 6257 | We don't need them in glr.cc, and glr.c defines them. |
| 6258 | Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c |
| 6259 | assumes that defining it to anything is the same as defining |
| 6260 | it to 1. Problem reported by Paolo Bonzini. |
| 6261 | |
| 6262 | 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change) |
| 6263 | |
| 6264 | * data/c.m4 (b4_null, b4_case): Define. |
| 6265 | * src/output.c (prepare_symbols): Use b4_null. |
| 6266 | (user_actions_output): Use b4_case. |
| 6267 | |
| 6268 | 2006-09-11 Paul Eggert <eggert@cs.ucla.edu> |
| 6269 | |
| 6270 | * data/glr.c (b4_shared_declarations): Put start-header first, |
| 6271 | before any #includes that we generate, so that feature-test |
| 6272 | macros work. Problem reported by Michael Deutschmann in |
| 6273 | <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>. |
| 6274 | * data/lalr1.cc: Likewise. |
| 6275 | * doc/bison.texinfo (Prologue): Document that feature-test macros |
| 6276 | should be defined before any Bison declarations. |
| 6277 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns |
| 6278 | that depend on location.hh after, not before, Bison decls, since |
| 6279 | we now include location.hh after the first user prologue. |
| 6280 | |
| 6281 | * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by |
| 6282 | Sander Brandenburg in |
| 6283 | <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>. |
| 6284 | Also, fix minor white space and comment issues. |
| 6285 | (Prologue): Mention that it's better to define feature-test macros |
| 6286 | before Bison declarations. Problem reported by Michael Deutschmann. |
| 6287 | |
| 6288 | * README-cvs: Fix typo: "&" should be "&&". Problem reported |
| 6289 | by Jim Meyering. |
| 6290 | * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4. |
| 6291 | This adjusts to recent gnulib changes. |
| 6292 | |
| 6293 | 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6294 | |
| 6295 | Finish implementation of per-type %destructor/%printer. Discussed |
| 6296 | starting at |
| 6297 | <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html> |
| 6298 | and |
| 6299 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>. |
| 6300 | * NEWS (2.3+): Add a description of this feature to the default |
| 6301 | %destructor/%printer description. |
| 6302 | * doc/bison.texinfo (Freeing Discarded Symbols): Likewise. |
| 6303 | * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set): |
| 6304 | Invoke semantic_type_destructor_set or semantic_type_printer_set when a |
| 6305 | list node contains a semantic type. |
| 6306 | * src/symtab.c, src/symtab.h: Extend with a table that associates |
| 6307 | semantic types with their %destructor's and %printer's. |
| 6308 | (semantic_type_from_uniqstr, semantic_type_get, |
| 6309 | semantic_type_destructor_set, semantic_type_printer_set): New functions |
| 6310 | composing the public interface of that table. |
| 6311 | (symbol_destructor_get, symbol_destructor_location_get, |
| 6312 | symbol_printer_get, symbol_printer_location_get): If there's no |
| 6313 | per-symbol %destructor/%printer, look up the per-type before trying |
| 6314 | the default. |
| 6315 | * tests/actions.at (Per-type %printer and %destructor): New test case. |
| 6316 | * tests/input.at (Default %printer and %destructor redeclared): |
| 6317 | Extend to check that multiple occurrences of %symbol-default in a |
| 6318 | single %destructor/%printer declaration is an error. |
| 6319 | (Per-type %printer and %destructor redeclared, Unused values with |
| 6320 | per-type %destructor): New test cases. |
| 6321 | |
| 6322 | 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6323 | |
| 6324 | Require default %destructor/%printer to be declared using |
| 6325 | %symbol-default instead of an empty symbol list, and start working on |
| 6326 | new per-type %destructor/%printer. Discussed at |
| 6327 | <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>. |
| 6328 | * NEWS (2.3+): Add %symbol-default to example. |
| 6329 | * bison.texinfo (Freeing Discarded Symbols): Likewise. |
| 6330 | (Table of Symbols): Add entry for %symbol-default. |
| 6331 | * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token. |
| 6332 | (generic_symlist, generic_symlist_item): New nonterminals for creating |
| 6333 | a list in which each item is a symbol, semantic type, or |
| 6334 | %symbol-default. |
| 6335 | (grammar_declaration): Use generic_symlist in %destructor and %printer |
| 6336 | declarations instead of symbols.1 or an empty list. |
| 6337 | (symbol_declaration, precedence_declaration, symbols.1): Update actions |
| 6338 | for changes to symbol_list. |
| 6339 | * src/reader.c: Update for changes to symbol_list. |
| 6340 | * src/scan-code.l: Likewise. |
| 6341 | * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token. |
| 6342 | * src/symlist.c, src/symlist.h: Extend such that a list node may |
| 6343 | represent a semantic type or a %symbol-default in addition to just an |
| 6344 | ordinary symbol. Add switched functions for setting %destructor's and |
| 6345 | %printer's. |
| 6346 | * tests/actions.at, tests/input.at: Add %symbol-default to all default |
| 6347 | %destructor/%printer declarations. |
| 6348 | |
| 6349 | 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6350 | |
| 6351 | Whether the default %destructor/%printer applies to a particular symbol |
| 6352 | isn't a question of whether the user *declares* that symbol (in %token, |
| 6353 | for example). It's a question of whether the user by any means |
| 6354 | *defines* the symbol at all (by simply using a char token, for |
| 6355 | example). $end is defined by Bison whereas any other token with token |
| 6356 | number 0 is defined by the user. The error token is always defined by |
| 6357 | Bison regardless of whether the user declares it with %token, but we |
| 6358 | may one day let the user define error as a nonterminal instead. |
| 6359 | * NEWS (2.3+): Say "user-defined" instead of "user-declared". |
| 6360 | * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document |
| 6361 | the meaning of "user-defined". |
| 6362 | * tests/actions.at (Default %printer and %destructor for user-declared |
| 6363 | end token): Rename to... |
| 6364 | (Default %printer and %destructor for user-defined end token): ... |
| 6365 | this. |
| 6366 | |
| 6367 | * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the |
| 6368 | computation of whether to apply the default, don't maintain a list of |
| 6369 | every Bison-defined symbol. Instead, just check for a first character |
| 6370 | of '$', which a user symbol cannot have, and check for the error token. |
| 6371 | |
| 6372 | 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6373 | |
| 6374 | Don't apply the default %destructor or %printer to the error token, |
| 6375 | $undefined, or $accept. This change fits the general rule that the |
| 6376 | default %destructor and %printer are only for user-declared symbols, |
| 6377 | and it solves several difficulties that are described in the new test |
| 6378 | cases listed below. |
| 6379 | * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement. |
| 6380 | * tests/actions.at (Default %printer and %destructor are not for error |
| 6381 | or $undefined, Default %printer and %destructor are not for $accept): |
| 6382 | New test cases. |
| 6383 | |
| 6384 | 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6385 | |
| 6386 | Allow %start after the first rule. |
| 6387 | * src/reader.c (grammar_current_rule_begin): Don't set the start symbol |
| 6388 | when parsing the first rule. |
| 6389 | (check_and_convert_grammar): Search for it here after all grammar |
| 6390 | declarations have been parsed. Skip midrules, which have dummy LHS |
| 6391 | nonterminals. |
| 6392 | * src/symtab.c (symbol_is_dummy): New function. |
| 6393 | * src/symtab.h (symbol_is_dummy): Declare it. |
| 6394 | * tests/input.at (%start after first rule): New test. |
| 6395 | |
| 6396 | 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6397 | |
| 6398 | Redo some of the previous commit: add back the ability to use |
| 6399 | non-aliased/undeclared string literals since it might be useful to |
| 6400 | those declaring %token-table. |
| 6401 | * src/reader.c (check_and_convert_grammar): Undo changes in previous |
| 6402 | commit: don't worry about complaints from symbols_pack. |
| 6403 | * src/symtab.c (symbol_new, symbol_class_set, |
| 6404 | symbol_check_alias_consistency): Undo changes in previous commit: count |
| 6405 | each string literal as a new symbol and token, assign it a symbol |
| 6406 | number, and don't complain about non-aliased string literals. |
| 6407 | (symbols_pack): Since symbol_make_alias still does not decrement symbol |
| 6408 | and token counts but does still set aliased tokens to the same number, |
| 6409 | symbol_pack_processor now leaves empty slots in the symbols array. |
| 6410 | Remove those slots. |
| 6411 | * tests/regression.at (Undeclared string literal): Remove test case |
| 6412 | added in previous commit since non-aliased string literals are allowed |
| 6413 | again. |
| 6414 | (Characters Escapes, Web2c Actions): Undo changes in previous commit: |
| 6415 | remove unnecessary string literal declarations. |
| 6416 | * tests/sets.at (Firsts): Likewise. |
| 6417 | |
| 6418 | 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6419 | |
| 6420 | Don't allow an undeclared string literal, but allow a string literal to |
| 6421 | be used before its declaration. |
| 6422 | * src/reader.c (check_and_convert_grammar): Don't invoke packgram if |
| 6423 | symbols_pack complained. |
| 6424 | * src/symtab.c (symbol_new): Don't count a string literal as a new |
| 6425 | symbol. |
| 6426 | (symbol_class_set): Don't count a string literal as a new token, and |
| 6427 | don't assign it a symbol number since symbol_make_alias does that. |
| 6428 | (symbol_make_alias): It's not necessary to decrement the symbol and |
| 6429 | token counts anymore. Don't assume that an alias declaration occurs |
| 6430 | before any uses of the identifier or string, and thus don't assert that |
| 6431 | one of them has the highest symbol number so far. |
| 6432 | (symbol_check_alias_consistency): Complain if there's a string literal |
| 6433 | that wasn't declared as an alias. |
| 6434 | (symbols_pack): Bail if symbol_check_alias_consistency failed since |
| 6435 | symbol_pack asserts that every token has been assigned a symbol number |
| 6436 | although undeclared string literals have not. |
| 6437 | * tests/regression.at (String alias declared after use, Undeclared |
| 6438 | string literal): New test cases. |
| 6439 | (Characters Escapes, Web2c Actions): Declare string literals as |
| 6440 | aliases. |
| 6441 | * tests/sets.at (Firsts): Likewise. |
| 6442 | |
| 6443 | 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6444 | |
| 6445 | In the grammar scanner, STRING_FINISH unclosed constructs and return |
| 6446 | them to the parser in order to improve error messages. |
| 6447 | * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER, |
| 6448 | SC_BRACED_CODE, SC_PROLOGUE): Implement. |
| 6449 | * tests/input.at (Unclosed constructs): New test case. |
| 6450 | * tests/regression.at (Invalid inputs): Update now that unclosed %{ is |
| 6451 | seen. |
| 6452 | |
| 6453 | * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove |
| 6454 | unused global. |
| 6455 | |
| 6456 | 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6457 | |
| 6458 | Handle string aliases for character tokens correctly. |
| 6459 | * src/symtab.c (symbol_user_token_number_set): If the token has an |
| 6460 | alias, check and set its alias's user token number instead of its own, |
| 6461 | which is set to indicate the alias. Previously, every occurrence of |
| 6462 | the character token in the grammar overwrote that alias indicator with |
| 6463 | the character code. |
| 6464 | * tests/input.at (String aliases for character tokens): New test. |
| 6465 | |
| 6466 | 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6467 | |
| 6468 | * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts. |
| 6469 | |
| 6470 | 2006-08-11 Paul Eggert <eggert@cs.ucla.edu> |
| 6471 | |
| 6472 | * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT, |
| 6473 | to prevent failures when building on older platforms. |
| 6474 | Check for autopoint failure. |
| 6475 | Set XGETTEXT_OPTIONS to values that check for C format strings, |
| 6476 | so that translators are warned about them (this also helps |
| 6477 | prevent core dumps). |
| 6478 | |
| 6479 | * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer |
| 6480 | function, since it simplifies our code a bit. |
| 6481 | |
| 6482 | * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare |
| 6483 | rather than -W, so we don't get bogus warnings about sign comparisons. |
| 6484 | Add -Wpointer-arith, since that warning is useful (it reports code |
| 6485 | that does not conform to C89 and that some compilers reject). |
| 6486 | * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change, |
| 6487 | since it's no longer needed. |
| 6488 | |
| 6489 | 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6490 | |
| 6491 | Clean up scanners a bit. |
| 6492 | * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack |
| 6493 | definitions so gcc won't warn when obstack_for_string is unused. |
| 6494 | * src/scan-code.l: config.h and system.h are already #include'd by |
| 6495 | scan-code-c.c, so get rid of them here. |
| 6496 | * src/scan-gram.l: Likewise. |
| 6497 | * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack |
| 6498 | definitions rather than duplicating the rest of it. |
| 6499 | * src/scan-gram-c.c, scan-skel-c.c: #include "system.h". |
| 6500 | |
| 6501 | 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6502 | |
| 6503 | Suppress signed/unsigned comparison warnings for yycheck. |
| 6504 | * data/c.m4 (b4_safest_int_type): New macro. |
| 6505 | * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against |
| 6506 | a signed int type, cast it to b4_safest_int_type first. |
| 6507 | * data/yacc.c: Likewise. |
| 6508 | (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is |
| 6509 | also overwritten. |
| 6510 | |
| 6511 | 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change) |
| 6512 | |
| 6513 | * doc/bison.texinfo: Fix some typos. |
| 6514 | |
| 6515 | 2006-08-02 Paul Eggert <eggert@cs.ucla.edu> |
| 6516 | |
| 6517 | * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4, |
| 6518 | po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4. |
| 6519 | |
| 6520 | * bootstrap (gnulib_tool): Stop using --assume-autoconf; |
| 6521 | the latest gnulib does this a different way. |
| 6522 | (get_translations): Sharuzzaman Ahmat Raslan reported that the ms |
| 6523 | translation was patched, so stop omitting it. |
| 6524 | |
| 6525 | 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6526 | |
| 6527 | Enable declaration of default %printer/%destructor. Make the parser |
| 6528 | use these for all user-declared grammar symbols for which the user does |
| 6529 | not declare a specific %printer/%destructor. Thus, the parser uses it |
| 6530 | for token 0 if the user declares it but not if Bison generates it as |
| 6531 | $end. Discussed starting at |
| 6532 | <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>, |
| 6533 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>, |
| 6534 | and |
| 6535 | <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>. |
| 6536 | * NEWS (2.3+): Mention. |
| 6537 | * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to |
| 6538 | declare a %destructor for a mid-rule's semantic value. It's just |
| 6539 | impossible to declare one specific to it. |
| 6540 | (Freeing Discarded Symbols): Mention that @$ can be used in %destructor |
| 6541 | code. Describe default %destructor form. |
| 6542 | * src/parse-gram.y (grammar_declaration): Parse default |
| 6543 | %printer/%destructor declarations. |
| 6544 | * src/output.c (symbol_destructors_output): Use symbol_destructor_get |
| 6545 | and symbol_destructor_location_get rather than accessing the destructor |
| 6546 | and destructor_location members of struct symbol. |
| 6547 | (symbol_printers_output): Likewise but for %printer's. |
| 6548 | * src/reader.c (symbol_should_be_used): Likewise but for %destructor's |
| 6549 | again. |
| 6550 | * src/symtab.c (default_destructor, default_destructor_location, |
| 6551 | default_printer, default_printer_location): New static global |
| 6552 | variables to record the default %destructor and %printer. |
| 6553 | (symbol_destructor_get, symbol_destructor_location_get, |
| 6554 | symbol_printer_get, symbol_printer_location_get): New functions to |
| 6555 | compute the appropriate %destructor and %printer for a symbol. |
| 6556 | (default_destructor_set, default_printer_set): New functions to set the |
| 6557 | default %destructor and %printer. |
| 6558 | * src/symtab.h: Prototype all those new functions. |
| 6559 | * tests/actions.at (Default %printer and %destructor): New test to |
| 6560 | check that the right %printer and %destructor are called, that they're |
| 6561 | not called for $end, and that $$ and @$ work correctly. |
| 6562 | (Default %printer and %destructor for user-declared end token): New |
| 6563 | test to check that the default %printer and %destructor are called for |
| 6564 | a user-declared end token. |
| 6565 | * tests/input.at (Default %printer and %destructor redeclared, Unused |
| 6566 | values with default %destructor): New tests to check related grammar |
| 6567 | warnings and errors. |
| 6568 | |
| 6569 | 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6570 | |
| 6571 | Clean up handling of %destructor for the end token (token 0). |
| 6572 | Discussed starting at |
| 6573 | <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html> |
| 6574 | and |
| 6575 | <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>. |
| 6576 | |
| 6577 | Make the skeletons consistent in how they pop the end token and invoke |
| 6578 | its %destructor. |
| 6579 | * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start |
| 6580 | state, which has token number 0, since this would invoke the |
| 6581 | %destructor for the end token. |
| 6582 | * data/lalr1.cc (yy::parser::parse): Don't check for the final state |
| 6583 | until after shifting the end token, or else it won't be popped. |
| 6584 | * data/yacc.c (yyparse): Likewise. |
| 6585 | |
| 6586 | * data/glr.c (yyparse): Clear the lookahead after shifting it even when |
| 6587 | it's the end token. Upon termination, destroy an unshifted lookahead |
| 6588 | even when it's the end token. |
| 6589 | * data/lalr1.cc (yy::parser::parse): Likewise. |
| 6590 | * data/yacc.c (yyparse): Likewise. |
| 6591 | |
| 6592 | * src/reader.c (packgram): Don't check rule 0. This suppresses unused |
| 6593 | value warnings for the end token when the user gives the end token a |
| 6594 | %destructor. |
| 6595 | |
| 6596 | * tests/actions.at (Printers and Destructors): Test all the above. |
| 6597 | |
| 6598 | 2006-07-24 Paul Eggert <eggert@cs.ucla.edu> |
| 6599 | |
| 6600 | Update to latest gnulib and gettext versions. |
| 6601 | * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer. |
| 6602 | Add fopen-safer. |
| 6603 | (gnulib_files): Add m4/warning.m4. Don't worry about files |
| 6604 | overwritten by autopoint. |
| 6605 | Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4. |
| 6606 | Suppress "id", "ms", "tr" translations for now, since gettext 0.15 |
| 6607 | rejects them. |
| 6608 | Don't use autoreconf; instead, invoke autopoint etc. by hand, |
| 6609 | so that we can remove the intl files at a better time. |
| 6610 | (intl_files_to_remove): Remove aclocal.m4, since it gets |
| 6611 | rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4, |
| 6612 | m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4, |
| 6613 | m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4. |
| 6614 | Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4. |
| 6615 | Remove datarootdir hack; no longer needed. |
| 6616 | * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING. |
| 6617 | (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15. |
| 6618 | * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c, |
| 6619 | strdup.h. |
| 6620 | * m4/.cvsignore: Remove hard-locale.m4, strdup.m4. |
| 6621 | * m4/warning.m4: Remove from CVS, since we now use gnulib's version. |
| 6622 | |
| 6623 | 2006-07-20 Paul Eggert <eggert@cs.ucla.edu> |
| 6624 | |
| 6625 | * bootstrap: Adjust to today's change to gnulib-tool by invoking |
| 6626 | it with --assume-autoconf='latest-stable'. |
| 6627 | |
| 6628 | 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6629 | |
| 6630 | * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at |
| 6631 | least 1.4.7 and 1.4.4) by putting a #line between `typedef union |
| 6632 | YYSTYPE' and `{'. |
| 6633 | * src/muscle_tab.h (muscle_grow): Replace the header comments with |
| 6634 | those from muscle_tab.c since the old ones are misleading. |
| 6635 | |
| 6636 | 2006-07-13 Akim Demaille <akim@epita.fr> |
| 6637 | |
| 6638 | Support %define "KEY" {VALUE}. |
| 6639 | * src/scan-code.h, src/scan-code.l (translate_action) |
| 6640 | (translate_rule_action, translate_symbol_action, translate_code): |
| 6641 | Return char *, not const char *. |
| 6642 | * src/parse-gram.y (declaration): Rename as... |
| 6643 | (prologue_declaration): this. |
| 6644 | (string_content): Remove this nonterminal, use STRING. |
| 6645 | (braceless, content, content.opt): New nonterminal. |
| 6646 | Use them. |
| 6647 | (%define): Now accept content.opt, i.e., accept also BRACED_CODE |
| 6648 | as value. |
| 6649 | * src/scan-gram.l (getargs.h): Don't include it. |
| 6650 | |
| 6651 | 2006-07-12 Paul Eggert <eggert@cs.ucla.edu> |
| 6652 | |
| 6653 | * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)' |
| 6654 | rather than a for-loop that declares a local bool variable. This |
| 6655 | should work around a compatibility problem with a Cray x1e C++ |
| 6656 | compiler reported by Hung Nguyen in |
| 6657 | <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>. |
| 6658 | The for-loop was introduced in the 2004-11-17 change but I don't |
| 6659 | know why it was needed. |
| 6660 | |
| 6661 | 2006-07-12 Akim Demaille <akim@epita.fr> |
| 6662 | |
| 6663 | * data/c.m4: Comment changes. |
| 6664 | |
| 6665 | 2006-07-10 Akim Demaille <akim@lrde.epita.fr> |
| 6666 | |
| 6667 | * src/complain.c (error_message, ERROR_MESSAGE): New. |
| 6668 | To factor... |
| 6669 | (fatal_at, fatal, warn_at, warn, complain_at, complain): these. |
| 6670 | * src/complain.h, src/complain.c (warning_issued): Remove, unused. |
| 6671 | |
| 6672 | 2006-07-09 Paul Eggert <eggert@cs.ucla.edu> |
| 6673 | |
| 6674 | * NEWS: Instead of %union, you can define and use your own union type |
| 6675 | YYSTYPE if your grammar contains at least one <type> tag. |
| 6676 | Your YYSTYPE need not be a macro; it can be a typedef. |
| 6677 | * doc/bison.texinfo (Value Type, Multiple Types, Location Type): |
| 6678 | (Union Decl, Decl Summary): Document this. |
| 6679 | * data/glr.c (YYSTYPE): Implement this. |
| 6680 | * data/glr.cc (YYSTYPE): Likewise. |
| 6681 | * data/lalr1.cc (YYSTYPE): Likewise. |
| 6682 | * data/yacc.c (YYSTYPE): Likewise. |
| 6683 | * src/output.c (prepare): Output tag_seen_flag. |
| 6684 | * src/parse-gram.y (declaration, grammar_declaration): |
| 6685 | Use 'union_seen' rather than 'typed' to determine whether |
| 6686 | %union has been seen, since grammars can now be typed without |
| 6687 | %union. |
| 6688 | (symbol_declaration, type.opt, symbol_def): |
| 6689 | Keep track of whether a tag has been seen. |
| 6690 | * src/reader.c (union_seen, tag_seen): New vars. |
| 6691 | (typed): remove. |
| 6692 | * src/reader.h (union_seen, tag_seen, typed): Likewise. |
| 6693 | * src/scan-code.l (untyped_var_seen): New variable. |
| 6694 | (handle_action_dollar): Adjust to above changes. |
| 6695 | (handle_action_dollar, handle_action_at): |
| 6696 | Improve overflow checking for outlandish numbers. |
| 6697 | * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to |
| 6698 | avoid new diagnostics generated by above changes. |
| 6699 | * tests/regression.at (YYSTYPE typedef): Add test to check |
| 6700 | for type tags without %union. |
| 6701 | |
| 6702 | * src/symlist.c (symbol_list_length): Return int, not unsigned |
| 6703 | int, since callers expect int. This may need to get revisited |
| 6704 | once we have proper integer overflow checking. |
| 6705 | |
| 6706 | * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this |
| 6707 | object is now static. |
| 6708 | |
| 6709 | * src/getargs.c (flags_argmatch): Return void, not int, |
| 6710 | to pacify ./configure --enable-gcc-warnings. |
| 6711 | |
| 6712 | * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string) |
| 6713 | since last_string is already defined to FLEX_PREFIX (last_string). |
| 6714 | |
| 6715 | 2006-07-09 Akim Demaille <akim@lrde.epita.fr> |
| 6716 | |
| 6717 | Implement --warnings/-W. |
| 6718 | * src/getargs.c (report_argmatch, trace_argmatch): Remove, |
| 6719 | replaced by... |
| 6720 | (flags_argmatch, FLAGS_ARGMATCH): this new function and macro. |
| 6721 | Adjust callers. |
| 6722 | * src/getargs.h, src/getargs.c (warnings, warnings_flags) |
| 6723 | (warnings_args, warnings_types): New. |
| 6724 | (getargs, short_options, long_options): Accept -W/--warnings. |
| 6725 | Sort the options by alphabetical order, upper case letter right |
| 6726 | before its lower case. |
| 6727 | |
| 6728 | 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6729 | |
| 6730 | Change %merge result type clash warnings to errors. Discussed at |
| 6731 | <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>. |
| 6732 | * src/reader.c (record_merge_function_type): Use complain_at. |
| 6733 | * tests/glr-regression.at (Missed %merge type warnings when LHS type is |
| 6734 | declared later): Update test case results. |
| 6735 | |
| 6736 | 2006-07-09 Akim Demaille <akim@lrde.epita.fr> |
| 6737 | |
| 6738 | * src/getargs.h, src/getargs.c: Swap --report and --trace handling |
| 6739 | to be in alphabetical order. |
| 6740 | (trace_args): Spelling fixes. |
| 6741 | |
| 6742 | 2006-07-09 Paul Eggert <eggert@cs.ucla.edu> |
| 6743 | |
| 6744 | * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy" |
| 6745 | so they don't collide with user-defined macros. |
| 6746 | (yy_stack_print): Don't assume that yytype_int16 promotes to int; |
| 6747 | this was never guaranteed, and now that we're using gnulib stdint, |
| 6748 | which defines int_fast16_t to long int, the problem is exposed. |
| 6749 | |
| 6750 | 2006-07-08 Paul Eggert <eggert@cs.ucla.edu> |
| 6751 | |
| 6752 | * data/c.m4 (b4_basename): Simplify a bit, since we don't |
| 6753 | need the full POSIX semantics (and weren't implementing them |
| 6754 | anyway). |
| 6755 | |
| 6756 | Adjust to Autoconf 2.60 and today's gnulib. |
| 6757 | * bootstrap (gnulib_modules): Add stdint. |
| 6758 | Remove special case for m4/onceonly_2_57.m4, since gnulib-tool |
| 6759 | no longer copies it. |
| 6760 | (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4, |
| 6761 | since stdint needs the former and wcwidth (which is now required |
| 6762 | by mbswidth) needs the latter. |
| 6763 | Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to |
| 6764 | work around a compatibility glitch between gettext 0.14.6 and |
| 6765 | Autoconf 2.60. |
| 6766 | * configure.ac (AC_PREREQ): Require Autoconf 2.60. |
| 6767 | Do not check for uintptr_t, since new stdint module does the right |
| 6768 | thing. |
| 6769 | * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h. |
| 6770 | Add stdint.h, stdint_.h, wcwidth.h. |
| 6771 | * m4/.cvsignore: Remove alloca.m4, onceonly.m4. |
| 6772 | Add absolute-header.m4, double-slash-root.m4, longlong.m4, |
| 6773 | stdint.m4, wchar_t.m4, wcwidth.m4. |
| 6774 | * src/files.c: Include <dirname.h> and <stdio-safer.h> in the |
| 6775 | usual order for ../lib/*.h files. |
| 6776 | (file_name_split): Use last_component, not base_name, to adjust |
| 6777 | to gnulib changes. |
| 6778 | * src/parse-gram.h: Include <strverscmp.h> in the usual order |
| 6779 | for ../lib/*.h files. |
| 6780 | (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8): |
| 6781 | Define unconditionally, since we now assume the stdint module. |
| 6782 | * src/scan-skel.l: Include <dirname.h>. |
| 6783 | (BASE_QPUTS): Use last_component, not base_name. |
| 6784 | * src/system.h: Include <unlocked-io.h> in the usual order |
| 6785 | for ../lib/*.h files. Include <stdint.h> unconditionally, |
| 6786 | since we now use the stdint module. |
| 6787 | (uintptr_t): Declare if UINTPTR_MAX is not defined, not |
| 6788 | HAVE_UINTPTR_T, since we now use the stdint module. |
| 6789 | (base_name): Remove decl, since files now include <dirname.h> |
| 6790 | to get the decl. |
| 6791 | |
| 6792 | 2006-07-08 Akim Demaille <akim@lrde.epita.fr> |
| 6793 | |
| 6794 | * data/c.m4 (b4_location_initial_column, b4_location_initial_line): |
| 6795 | New, default to 1. |
| 6796 | * data/yacc.c, data/glr.c, data/location.cc: Use them. |
| 6797 | * NEWS, doc/bison.texinfo: The initial column and line are 1 by |
| 6798 | default. |
| 6799 | * tests/calc.at: Adjust. |
| 6800 | |
| 6801 | 2006-07-08 Akim Demaille <akim@lrde.epita.fr> |
| 6802 | |
| 6803 | * data/c.m4 (b4_basename): New. |
| 6804 | (b4_syncline): Also output the location of its invocation (from |
| 6805 | the skeleton). |
| 6806 | (b4_user_action, b4_define_user_action, b4_user_actions) |
| 6807 | (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header) |
| 6808 | (b4_user_stype): New. |
| 6809 | * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them. |
| 6810 | |
| 6811 | 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6812 | |
| 6813 | In the grammar file, the first column is 1 not 0 on the first line as |
| 6814 | on every other line. |
| 6815 | * src/parse-gram.y (%initial-action): Initialize @$ correctly. |
| 6816 | * tests/input.at (Torturing the Scanner): Update output. |
| 6817 | |
| 6818 | * src/scan-gram.l (scanner_cursor): Declare it static. |
| 6819 | |
| 6820 | 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6821 | |
| 6822 | In warnings, say "previous declaration" rather than "first |
| 6823 | declaration". |
| 6824 | * src/symtab.c (redeclaration): Do that here. |
| 6825 | * src/reader.c (record_merge_function_type): In the case of a result |
| 6826 | type clash, report the previous declaration rather than the very first |
| 6827 | one in the grammar file. |
| 6828 | * tests/glr-regression.at (Missed %merge type warnings when LHS type is |
| 6829 | declared later): Add a third declaration to check this behavior. |
| 6830 | * tests/input.at (Incompatible Aliases): Update output. |
| 6831 | |
| 6832 | 2006-06-27 Akim Demaille <akim@epita.fr> |
| 6833 | |
| 6834 | * doc/Doxyfile.in: New. |
| 6835 | * doc/Makefile.am: Use it. |
| 6836 | * src/lalr.h, src/symtab.h: Initial doxygenation. |
| 6837 | |
| 6838 | 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6839 | |
| 6840 | Don't miss %merge result type warnings just because the LHS types are |
| 6841 | declared after the %merge. This continues the effort of the previous |
| 6842 | patch. |
| 6843 | * src/reader.c (get_merge_function): Don't set the merger type yet. |
| 6844 | (record_merge_function_type): New function for setting the merger type |
| 6845 | and checking for clashes. |
| 6846 | (grammar_current_rule_merge_set): Set the location of the %merge for |
| 6847 | the current rule. |
| 6848 | (packgram): Invoke record_merge_function_type for each rule now that |
| 6849 | all symbol type declarations have been parsed. |
| 6850 | * src/reader.h (merger_list.type_declaration_location): New member |
| 6851 | storing the location of the first %merge from which the type for this |
| 6852 | merging function was derived. |
| 6853 | * src/symlist.h (symbol_list.merger_declaration_location): New member |
| 6854 | storing the location of a rule's %merge, if any. |
| 6855 | * tests/glr-regression.at (Missed %merge type warnings when LHS type is |
| 6856 | declared later): New test to catch the error fixed by the above patch. |
| 6857 | |
| 6858 | 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6859 | |
| 6860 | Get action warnings (grammar_rule_check) right even when symbol |
| 6861 | declarations appear after the rules. Discussed at |
| 6862 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html> |
| 6863 | and |
| 6864 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>. |
| 6865 | Don't mistake the type of $$ in a midrule to be that of its parent |
| 6866 | rule's $$. |
| 6867 | * src/reader.c (grammar_current_rule_end): Don't invoke |
| 6868 | grammar_rule_check yet since not all symbol declarations may have been |
| 6869 | parsed yet. |
| 6870 | (grammar_midrule_action): Likewise. |
| 6871 | Don't record whether the midrule's $$ has been used yet since actions |
| 6872 | haven't been translated yet. |
| 6873 | Record the midrule's parent rule and its RHS index within the parent |
| 6874 | rule. |
| 6875 | (grammar_current_rule_action_append): Don't translate the action yet |
| 6876 | since not all symbol declarations may have been parsed yet and, thus, |
| 6877 | warnings about types for $$, $n, @$, and @n can't be reported yet. |
| 6878 | (packgram): Translate the action and invoke grammar_rule_check now that |
| 6879 | all symbol declarations have been parsed. |
| 6880 | * src/scan-code.l (handle_action_dollar): Now that this is invoked |
| 6881 | after parsing the entire grammar file, the symbol list here in the case |
| 6882 | of a midrule is actually the midrule's empty RHS, so reference its |
| 6883 | parent rule's RHS where necessary. |
| 6884 | On the other hand, now that you can already know it's a midrule, you |
| 6885 | aren't forced to think $$ has the same type as its parent rule's $$. |
| 6886 | (handle_action_at): In the case of a midrule, reference the parent rule |
| 6887 | where necessary. |
| 6888 | * src/symlist.c (symbol_list_new): Initialize new midrule-related |
| 6889 | members. |
| 6890 | (symbol_list_length): Now that this is invoked after all rules have |
| 6891 | been parsed, a NULL symbol (rather than a NULL symbol list node) |
| 6892 | terminates a rule. symbol_list_print already does this correctly. |
| 6893 | * src/symlist.h (symbol_list.midrule_parent_rule, |
| 6894 | symbol_list.midrule_parent_rhs_index): New members so that midrules can |
| 6895 | remember their relationships with their parents. |
| 6896 | * tests/input.at (Type Clashes): Extend to catch the midrule $$ error |
| 6897 | fixed by the above patch. |
| 6898 | (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros |
| 6899 | implementing... |
| 6900 | (Unused values): ... this old test case and... |
| 6901 | (Unused values before symbol declarations): ... this new test case. |
| 6902 | This one is the same as `Unused values' except that all symbol |
| 6903 | declarations appear after the rules in order to catch the rest of the |
| 6904 | errors fixed by the above patch. |
| 6905 | |
| 6906 | 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6907 | |
| 6908 | More cleanup. |
| 6909 | * src/reader.c (current_rule): Declare it static since it's no longer |
| 6910 | used outside this file. |
| 6911 | (grammar_current_rule_action_append): Remove redundant arguments from |
| 6912 | translate_rule_action invocation. |
| 6913 | * src/reader.h (current_rule): Remove this unused extern. |
| 6914 | * src/scan-code.h (translate_rule_action): Remove redundant arguments. |
| 6915 | * src/scan-code.l (translate_rule_action): Likewise. |
| 6916 | |
| 6917 | 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6918 | |
| 6919 | Clean up yesterday's patch. |
| 6920 | * parse-gram.y (rhs): Move grammar_midrule_action invocation from here |
| 6921 | to... |
| 6922 | * src/reader.c (grammar_current_rule_action_append): ... here for |
| 6923 | consistency with grammar_current_rule_symbol_append. |
| 6924 | * tests/regression.at (Braced code in declaration in rules section): |
| 6925 | Make yyerror and yylex static as usual. |
| 6926 | |
| 6927 | 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu> |
| 6928 | |
| 6929 | Fix bug that mistakes braced code in a declaration in the rules section |
| 6930 | to be a rule action. Mentioned at |
| 6931 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>. |
| 6932 | * src/scan-gram.l: Move midrule action detection from the start of the |
| 6933 | scanning of any braced code to... |
| 6934 | * src/parse-gram.y (rhs): ... the parsing of braced code as a rule |
| 6935 | action. For readability, use $2 and @2 rather than the equivalent |
| 6936 | global variables. |
| 6937 | * tests/regression.at (Braced code in declaration in rules section): |
| 6938 | New test to catch the error fixed by the above patch. |
| 6939 | |
| 6940 | Work on code readability some. |
| 6941 | * src/scan-code.l (current_rule): Get rid of this misleading and |
| 6942 | redundant declaration: it's actually extern'ed in reader.h. |
| 6943 | (YY_DECL, code_lex, handle_action_dollar, handle_action_at, |
| 6944 | translate_action): Add a rule argument and use it instead of the global |
| 6945 | current_rule. |
| 6946 | (translate_rule_action): This already receives current_rule through an |
| 6947 | argument, so pass it on to translate_action instead of assigning |
| 6948 | current_rule to current_rule. |
| 6949 | (translate_symbol_action, translate_code): Pass rule = NULL to |
| 6950 | translate_action. |
| 6951 | |

| 6953 | |
| 6954 | Rename %before-definitions to %start-header and %after-definitions to |
| 6955 | %end-header. Don't use these declarations to separate pre-prologue |
| 6956 | blocks from post-prologue blocks. Add new order-independent |
| 6957 | declarations %before-header and %after-header as alternatives to the |
| 6958 | traditional Yacc pre-prologue and post-prologue blocks. Discussed at |
| 6959 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>. |

| 6979 | When parsing %end-header and %start-header, invoke translate_code |
| 6980 | before muscle_code_grow, and no longer set global booleans to remember |
| 6981 | whether these declarations have been seen. |
| 6982 | Parse new %after-header and %before-header. |
| 6983 | * src/reader.c (before_definitions, after_definitions): Remove. |

| 6998 | Add comparison operators for C++ location classes. Discussed at |
| 6999 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>. |
| 7000 | * data/c++.m4 (b4_define_location_comparison): New boolean %define |
| 7001 | declaration indicating whether filename_type has an operator==. If |
| 7002 | filename_type is `std::string', it defaults to `1', `0' otherwise. |
| 7003 | * data/location.cc: Iff b4_define_location_comparison is `1', add |
| 7004 | operator== and operator!= for class position and for class location. |
| 7005 | |
| 7006 | Some minor fixes. |
| 7007 | * src/scan-action.l: Remove unused file. |
| 7008 | * src/symtab.c (symbol_printer_set): Use printer_location not |

| 7015 | 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7016 | |
| 7017 | Don't put the pre-prologue in the header file. For the yacc.c code |
| 7018 | file and the glr.c header and code files, move the pre-prologue before |
| 7019 | the token definitions. Add new %before-definitions and |
| 7020 | %after-definitions to declare code that will go in both the header file |
| 7021 | and code file. Discussed at |
| 7022 | <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>, |
| 7023 | <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>, |

| 7026 | * NEWS (2.3+): Describe these changes. |
| 7027 | * data/glr.c (b4_pre_prologue): Move from within to before... |
| 7028 | (b4_shared_declarations): ... this. |
| 7029 | Add new b4_before_definitions before b4_token_enums. |
| 7030 | Add new b4_after_definitions at the end. |
| 7031 | * data/glr.cc (b4_pre_prologue): Replace with... |
| 7032 | (b4_before_definitions): ... this in the header file. |
| 7033 | (b4_after_definitions): New near the end of the header file. |
| 7034 | * data/lalr1.cc (b4_pre_prologue): Move from the header file to the |
| 7035 | code file right before including the header file. |
| 7036 | (b4_before_definitions): New in the previous position of |
| 7037 | b4_pre_prologue in the header file. |
| 7038 | (b4_after_definitions): New near the end of the header file. |
| 7039 | * data/yacc.c: Clean up some m4 quoting especially in the header file. |
| 7040 | (b4_token_enums_defines): In the code file, move to right before |
| 7041 | YYSTYPE for consistency with the header file. |
| 7042 | (b4_before_definitions): New right before b4_token_enums_defines in |
| 7043 | both the header and code file. |
| 7044 | (b4_after_definitions): New right after YYLTYPE and yylloc in both the |
| 7045 | header and code file. |
| 7046 | * doc/bison.texinfo (Prologue): Show use of %before-definitions instead |
| 7047 | of prologues for %union dependencies. |
| 7048 | (Decl Summary): In %defines description, mention the effect of |
| 7049 | %before-definitions and %after-definitions on the header file. |
| 7050 | (Calc++ Parser): Forward declare driver in a %before-definitions rather |
| 7051 | than in the pre-prologue so that make check succeeds. |
| 7052 | (Table of Symbols): Add entries for %before-definitions and |
| 7053 | %after-definitions. |
| 7054 | * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for |
| 7055 | %before-definitions. |
| 7056 | (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions. |
| 7057 | (declaration): Parse those declarations and append to |
| 7058 | b4_before_definitions and b4_after_definitions, respectively. |
| 7059 | * src/reader.c (before_definitions, after_definitions): New bools to |
| 7060 | track whether those declarations have been seen. |
| 7061 | (prologue_augment): Add to the post-prologue if %union, |
| 7062 | %before-definitions, or %after-definitions has been seen. |
| 7063 | * src/reader.h (before_definitions, after_definitions): New extern's. |
| 7064 | * src/scan-gram.l: Scan the new declarations. |
| 7065 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second |
| 7066 | prologue block in a %before-definitions or a %after-definitions based |
| 7067 | on whether the %union is declared. |
| 7068 | * tests/regression.at (Early token definitions with --yacc, Early token |
| 7069 | definitions without --yacc): Move tests for token definitions into the |
| 7070 | post-prologue since token names are no longer defined in the |
| 7071 | pre-prologue. |
| 7072 | |
| 7073 | 2006-06-20 Akim Demaille <akim@epita.fr> |

| 7078 | |
| 7079 | 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7080 | |
| 7081 | * src/scan-gram.l: Remove unused declaration of last_string_1 so the |
| 7082 | build succeeds when configured with --enable-gcc-warnings. |
| 7083 | |
| 7084 | 2006-06-19 Paul Eggert <eggert@cs.ucla.edu> |
| 7085 | |
| 7086 | * src/parse-gram.y (char_name): New function. |
| 7087 | (CHAR, STRING, string_content): For %printer, properly escape. |
| 7088 | (ID): Prefer fputs to fprintf. |
| 7089 | (id): Reindent to be consistent with other rules. |
| 7090 | Properly quote char. |
| 7091 | |
| 7092 | The Translation Project changed its way of publishing translations |
| 7093 | to maintainers. I haven't received any responses to my request |
| 7094 | for supporting the old way, or for documenting the new way. I |
| 7095 | have modified 'bootstrap' to use screen scraping |
| 7096 | (in this case, HTML scraping). This is unreliable and inelegant, |
| 7097 | but I don't see any better way. Yuck. |
| 7098 | * bootstrap (TP_URL, WGET_COMMAND): New vars. |
| 7099 | (get_translations): New function, which uses HTML scraping to |
| 7100 | deduce locations of latest translations. |
| 7101 | Use this function to grab both bison and bison-runtime .po files. |
| 7102 | Don't bother priming the pump for the runtime-po domain any more, |
| 7103 | as it's now translated better than bison is. |
| 7104 | |
| 7105 | 2006-06-19 Akim Demaille <akim@epita.fr> |
| 7106 | |
| 7107 | * src/scan-gram.l: No longer "parse" things after `%union' until |
| 7108 | `{'. Rather, return a single "%union" token. |
| 7109 | No longer make symbols: return strings, and leave the conversion |
| 7110 | to symbols to the parser. |
| 7111 | (SC_PRE_CODE, token_type): Remove. |
| 7112 | * src/parse-gram.y (%union): New field `character'. |
| 7113 | Sort tokens. |
| 7114 | (CHAR): New token. |
| 7115 | (ID, ID_COLON): Now that the scanner no longer makes them |
| 7116 | identifiers, adjust all uses to invoke symbol_get. |
| 7117 | (id_colon): New, wraps the conversion from string to symbol. |
| 7118 | (%union): Accept a possible union_name. |
| 7119 | (symbol): Now can be a char. |
| 7120 | * data/c.m4 (b4_union_name): Leave a default value. |
| 7121 | * data/glr.c, data/yacc.c: Use it. |
| 7122 | |
| 7123 | 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7124 | |
| 7125 | For associating token numbers with token names for "yacc.c", don't use |
| 7126 | #define statements unless `--yacc' is specified; always use enum |
| 7127 | yytokentype. Most important discussions start at: |
| 7128 | <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>, |
| 7129 | <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>, |

| 7131 | <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>. |
| 7132 | * NEWS (2.3+): Mention. |
| 7133 | * data/c.m4 (b4_yacc_if): New. |
| 7134 | (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the |
| 7135 | token #define's. |
| 7136 | * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc' |
| 7137 | on token name definitions. |
| 7138 | * src/getargs.c (usage): Capitalize `Yacc' in English. |
| 7139 | * src/output.c (prepare): Define b4_yacc_flag. |
| 7140 | * tests/regression.at (Early token definitions): Test that tokens names |
| 7141 | are defined before the pre-prologue not just before the post-prologue. |
| 7142 | Remove this test case and copy to... |
| 7143 | (Early token definitions with --yacc): ... this to test #define's. |
| 7144 | (Early token definitions without --yacc): ... and this to test enums. |
| 7145 | |
| 7146 | 2006-06-11 Paul Eggert <eggert@cs.ucla.edu> |
| 7147 | |
| 7148 | * NEWS: Reword the post-2.3 change to not be so optimistic about |
| 7149 | removing the old "look-ahead" spelling. |
| 7150 | Update previous look-ahead/lookahead change reports. |
| 7151 | * REFERENCES: look-ahead -> lookahead (since that's |
| 7152 | what he actually wrote). |
| 7153 | * doc/refcard.tex: look ahead -> lookahead, |

| 7155 | |
| 7156 | 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7157 | |
| 7158 | For consistency, use `lookahead' instead of `look-ahead' or |
| 7159 | `look_ahead'. Discussed starting at |
| 7160 | <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html> |

| 7238 | 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7239 | |
| 7240 | * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng |
| 7241 | and yytext if they're already #define'd. |
| 7242 | * src/flex-scanner.h, src/location.h: Move #include "system.h" to... |

| 7244 | * src/scan-code.l, src/scan-gram.l: ... and here. Also #include |

| 7249 | Get Bison to build again when configured with --enable-gcc-warnings. |
| 7250 | * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some |
| 7251 | missing #include's. |
| 7252 | * src/scan-code.l (handle_action_dollar, handle_action_at): Rename |
| 7253 | loc argument as it shadows a global. |
| 7254 | * src/scan-gram.l: Remove stray comma that prevents boundary_set |
| 7255 | invocation. |
| 7256 | |
| 7257 | * src/.cvsignore: Add scan-code.c. |
| 7258 | |
| 7259 | 2006-06-07 Akim Demaille <akim@epita.fr> |
| 7260 | |

| 7262 | to... |

| 7264 | * tests/input.at (Torturing the Scanner): Fix another location |
| 7265 | error. |
| 7266 | |
| 7267 | 2006-06-07 Akim Demaille <akim@epita.fr> |
| 7268 | |
| 7269 | * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash. |
| 7270 | |
| 7271 | 2006-06-06 Akim Demaille <akim@epita.fr> |
| 7272 | |
| 7273 | Extract the parsing of user actions from the grammar scanner. |
| 7274 | As a consequence, the relation between the grammar scanner and |
| 7275 | parser is much simpler. We can also split "composite tokens" back |
| 7276 | into simple tokens. |
| 7277 | * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New. |
| 7278 | * src/scan-gram.l (add_column_width, adjust_location): Move to and |
| 7279 | rename as... |
| 7280 | * src/location.h, src/location.c (add_column_width) |
| 7281 | (location_compute): these. |
| 7282 | Fix the column count: the initial column is 0. |
| 7283 | (location_print): Be robust to ending column being 0. |
| 7284 | * src/location.h (boundary_set): New. |
| 7285 | * src/main.c: Adjust to scanner_free being renamed as |
| 7286 | gram_scanner_free. |
| 7287 | * src/output.c: Include scan-code.h. |
| 7288 | * src/parse-gram.y: Include scan-gram.h and scan-code.h. |
| 7289 | Use boundary_set. |
| 7290 | (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION) |
| 7291 | (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part, |
| 7292 | which is now, again, a separate token. |
| 7293 | Adjust all dependencies. |
| 7294 | Whereever actions with $ and @ are used, use translate_code. |
| 7295 | (action): Remove this nonterminal which is now useless. |
| 7296 | * src/reader.c: Include assert.h, scan-gram.h and scan-code.h. |
| 7297 | (grammar_current_rule_action_append): Use translate_code. |
| 7298 | (packgram): Bound check ruleno, itemno, and rule_length. |

| 7301 | (scanner_initialize, scanner_free, scanner_last_string_free) |
| 7302 | (gram_out, gram_lineno, YY_DECL_): Move to... |

| 7304 | (YY_DECL): Rename as... |
| 7305 | (GRAM_DECL): this. |
| 7306 | * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New. |
| 7307 | * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out): |
| 7308 | (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in): |
| 7309 | (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy): |
| 7310 | Move these declarations, and... |
| 7311 | (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE): |
| 7312 | these to... |
| 7313 | * src/flex-scanner.h: this new file. |
| 7314 | * src/scan-gram.l (rule_length, rule_length_overflow) |
| 7315 | (increment_rule_length): Remove. |
| 7316 | (last_braced_code_loc): Rename as... |
| 7317 | (gram_last_braced_code_loc): this. |
| 7318 | Adjust to the changes of the parser. |
| 7319 | Move all the handling of $ and @ into... |
| 7320 | * src/scan-code.l: here. |
| 7321 | * src/scan-gram.l (handle_dollar, handle_at): Remove. |
| 7322 | (handle_action_dollar, handle_action_at): Move to... |

| 7324 | * src/Makefile.am (bison_SOURCES): Add flex-scanner.h, |
| 7325 | scan-code.h, scan-code-c.c, scan-gram.h. |
| 7326 | (EXTRA_bison_SOURCES): Add scan-code.l. |
| 7327 | (BUILT_SOURCES): Add scan-code.c. |
| 7328 | (yacc): Be robust to white spaces. |
| 7329 | |
| 7330 | * tests/conflicts.at, tests/input.at, tests/reduce.at, |
| 7331 | * tests/regression.at: Adjust the column numbers. |
| 7332 | * tests/regression.at: Adjust the error message. |
| 7333 | |
| 7334 | 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7335 | |
| 7336 | * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output. |
| 7337 | Use Akim's wording from |
| 7338 | <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>. |

| 7341 | |
| 7342 | Between Bison releases, manually append `+' to the previous Bison |
| 7343 | release number, and use that as a signal to automatically print the |
| 7344 | ChangeLog's CVS Id keyword from --version. Discussed starting at |
| 7345 | <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>. |
| 7346 | * ChangeLog: Add Id header. |
| 7347 | * configure.ac (AC_INIT): Append `+' to `2.3'. |
| 7348 | * src/.cvsignore: Add revision.c. |
| 7349 | * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h. |
| 7350 | (BUILT_SOURCES): Add revision.c. |
| 7351 | (revision.c): New target rule. This file defines a new global variable |
| 7352 | named revision. It initializes it with either the Id from ChangeLog |
| 7353 | or, if VERSION doesn't contain `+', with the empty string. |
| 7354 | * src/getargs.c (version): Print the value of revision. |
| 7355 | * src/revision.h: Extern revision. |

| 7363 | |
| 7364 | * data/glr.c (YYRECOVERING): Define to be a function-like macro |
| 7365 | with no arguments, not as an object-like macro. This is for |
| 7366 | compatibility with data/yacc.c. Problem reported by John P. Hartmann in |
| 7367 | <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>. |
| 7368 | * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols): |
| 7369 | Document this. |
| 7370 | |
| 7371 | 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7372 | |
| 7373 | * src/getargs.c (usage): Back out yesterday's modification of the |
| 7374 | --help output so that we don't have to wait for translation before |
| 7375 | releasing 2.3. |
| 7376 | |
| 7377 | 2006-05-29 Paul Eggert <eggert@cs.ucla.edu> |
| 7378 | |
| 7379 | * doc/bison.texinfo (Introduction): Don't say "GLR grammar". |
| 7380 | Problem reported by Akim Demaille. |
| 7381 | |
| 7382 | 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7383 | |
| 7384 | * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output. |
| 7385 | |
| 7386 | 2006-05-26 Paul Eggert <eggert@cs.ucla.edu> |
| 7387 | |
| 7388 | * data/yacc.c (yy_reduce_print): Omit trailing white space in |
| 7389 | generated source code. Problem reported by Frans Englich in |
| 7390 | <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>. |
| 7391 | |
| 7392 | 2006-05-22 Paul Eggert <eggert@cs.ucla.edu> |
| 7393 | |
| 7394 | * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the |
| 7395 | shell, not within 'make', so that 'make' by an ordinary builder |
| 7396 | (using GNU make) does not worry about configuring gzip. This also |
| 7397 | works around a bug reported independently by Keith Thompson and by |
| 7398 | Georg Schwarz, whereby gzip 1.2.4 --help would output usage on |
| 7399 | stderr rather than stdout, messing up the build logs. |
| 7400 | |
| 7401 | 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7402 | |
| 7403 | * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID |
| 7404 | to make sure that YYID will never be unused. This fixes a 'make |
| 7405 | maintainer-check' failure caused by the recent changes to the 'Trivial |
| 7406 | grammars' test case, which caused g++ 4.1.0 to complain that YYID was |
| 7407 | not used. |
| 7408 | * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case. |
| 7409 | |
| 7410 | 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7411 | |
| 7412 | * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the |
| 7413 | state before an empty RHS is always resolved here. Only the location |
| 7414 | of that state is guaranteed to be resolved, and that's enough. This |
| 7415 | fixes the remaining bug reported by Derek M. Jones in |
| 7416 | <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>. |
| 7417 | * tests/glr-regression.at (Uninitialized location when reporting |
| 7418 | ambiguity): Test the above case. |
| 7419 | Also, the embedded comments in this test case claim it checks the case |
| 7420 | of an empty RHS that has inherited the initial location. However, the |
| 7421 | corresponding LHS was already resolved, so yyresolveLocations didn't |
| 7422 | actually have reason to modify it. Fix this by forcing |
| 7423 | nondeterministic operation at the beginning of the parse. |
| 7424 | |
| 7425 | 2006-05-20 Paul Eggert <eggert@cs.ucla.edu> |
| 7426 | |
| 7427 | * data/c.m4 (b4_yy_symbol_print_generate): |
| 7428 | (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than |
| 7429 | 'const YYSTYPE', and similarly for YYLTYPE. This fixes one |
| 7430 | of the bugs reported today by Derek M Jones in |
| 7431 | <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>. |
| 7432 | * doc/bison.texinfo (Value Type): Document that YYSTYPE must be |
| 7433 | defined to be a type name without parens or brackets. |
| 7434 | (Location Type): Similarly for YYLTYPE. |
| 7435 | * tests/regression.at (Trivial grammars): Put in a test for this |
| 7436 | bug that will be caught by 'make maintainer-check' (though not, |
| 7437 | alas, by 'make check' unless your compiler is picky). |
| 7438 | |

| 7445 | |
| 7446 | * data/glr.c (yyreportTree): Make room in yystates for the state |
| 7447 | preceding the RHS. This fixes the segmentation fault reported by Derek |
| 7448 | M. Jones in |
| 7449 | <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>. |
| 7450 | (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing |
| 7451 | to the user. Reported for yyreportTree by Derek M. Jones later in the |
| 7452 | same thread. |
| 7453 | * THANKS: Add Derek M. Jones. |
| 7454 | Update my email address. |

| 7457 | 2006-05-14 Paul Eggert <eggert@cs.ucla.edu> |
| 7458 | |
| 7459 | * data/glr.c (yyreportSyntaxError): Fix off-by-one error in |
| 7460 | checking against YYLAST that caused the parser to miss a potential |
| 7461 | alternative in its diagnostic. |
| 7462 | Problem reported by Maria Jose Moron Fernandez in |
| 7463 | <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>. |
| 7464 | * data/lalr1.cc (yysyntax_error_): Likewise. |
| 7465 | * data/yacc.c (yysyntax_error): Likewise. |
| 7466 | * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for |
| 7467 | tokens, in case we run into an older C compiler. |
| 7468 | (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros. |
| 7469 | Use them to check for the off-by-one error fixed above. |
| 7470 | |
| 7471 | * data/yacc.c (yytnamerr): Fix typo: local var should be of type |
| 7472 | YYSIZE_T, not size_t. |
| 7473 | * tests/regression.at (Trivial grammars): New test, to catch |
| 7474 | the error fixed by the above patch. |
| 7475 | |

| 7497 | (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New. |

| 7515 | |
| 7516 | * data/c.m4 (b4_copyright): Put the special exception for Bison |

| 7518 | uses changed. Suggested by Akim Demaille. Also, wrap the |
| 7519 | copyright notice, in case it is longer than 80 columns. Replace |
| 7520 | comma by newline after title. |

| 7598 | * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'. |
| 7599 | * data/lalr1.cc (yytnameerr_): Move its definition into the namespace. |
| 7600 | * data/yacc.c, data/glr.c: Remove a useless `[]'. |
| 7601 | * doc/bison.texinfo: Document it. |
| 7602 | (Option Cross Key): Use @multitable in all formats. It looks |
| 7603 | nicer, even in TeX outputs. |
| 7604 | (Rules): Use the same code whatever the output type is. |
| 7605 | * tests/local.at (_AT_BISON_OPTION_PUSHDEFS) |
| 7606 | (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX. |

| 7628 | Fix two nits reported by twlevo, plus one more that I discovered. |

| 7631 | this is the usual Bison style. |
| 7632 | * src/location.h (location_print): Likewise. |
| 7633 | |
| 7634 | * src/reader.h (token_name): Likewise. |

| 7641 | and ask for Java. Don't hardwire OS version numbers. Add |
| 7642 | copyright notice. |
| 7643 | * m4/.cvsignore: Add unistd_h.m4, for latest gnulib. |

| 7647 | |
| 7648 | * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web |

| 7650 | we're describing capabilities not granting permission. |

| 7660 | const char -> char const. |
| 7661 | |
| 7662 | * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind): |

| 7671 | YYLLOC_DEFAULT. |
| 7672 | (yyresolveValue): Invoke yyresolveLocations before reporting an |
| 7673 | ambiguity. |
| 7674 | * doc/bison.texinfo (Default Action for Locations): Note |
| 7675 | YYLLOC_DEFAULT's usage for ambiguity locations. |

| 7680 | * tests/glr-regression.at (Leaked semantic values when reporting |
| 7681 | ambiguity): Remove unnecessary union and type declarations. |
| 7682 | (Leaked lookahead after nondeterministic parse syntax error): New test |
| 7683 | case. |
| 7684 | * data/glr.c (yyparse): Check for zero stacks remaining before |
| 7685 | attempting to shift the lookahead so that you don't lose it. |
| 7686 | |
| 7687 | 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7688 | |
| 7689 | Avoid memory leaks by not invoking longjmp in yyreportAmbiguity. |
| 7690 | * tests/glr-regression.at (Leaked semantic values when reporting |
| 7691 | ambiguity): New test case. |
| 7692 | * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return |
| 7693 | yyabort rather than invoking yyFail, which invokes longjmp. Remove the |
| 7694 | now unnecessary yystackp parameter. |
| 7695 | (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary |
| 7696 | destructors can be called. |
| 7697 | |
| 7698 | * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily |
| 7699 | in existing testcases. |
| 7700 | |
| 7701 | 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu> |
| 7702 | |
| 7703 | Don't leak semantic values for parent RHS when a user action cuts the |
| 7704 | parser, and clean up related code a bit. |
| 7705 | * tests/glr-regression.at (Leaked merged semantic value if user action |
| 7706 | cuts parse): Rename to... |
| 7707 | (Leaked semantic values if user action cuts parse): ... this. Add check |
| 7708 | for leaked parent RHS values. |
| 7709 | * data/glr.c (yydestroyGLRState): In debugging output, distinguish |
| 7710 | between an unresolved state (non-empty chain of semantic options) and |
| 7711 | an incomplete one (signaled by an empty chain). |
| 7712 | (yyresolveStates): Document the interface. Move all manipulation of a |
| 7713 | successfully or unsuccessfully resolved yyGLRState to... |
| 7714 | (yyresolveValue): ... here so that yyresolveValue always leaves a |
| 7715 | yyGLRState with consistent data and thus is easier to understand. |
| 7716 | Remove the yyvalp and yylocp parameters since they are always just |
| 7717 | taken from the yys parameter. When reporting a discarded merged value |
| 7718 | in debugging output, note that it is incompletely merged. Document the |
| 7719 | interface. |
| 7720 | (yyresolveAction): If resolving any of the RHS states fails, destroy |
| 7721 | them all rather than leaking them. Thus, as long as user actions are |
| 7722 | written to clean up the RHS correctly, yyresolveAction always cleans up |
| 7723 | the RHS of a semantic option. Document the interface. |

| 7788 | |
| 7789 | * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from |
| 7790 | nodist_PROGRAMS, since we don't need to actually compile the |

| 7826 | "warning: sorry: semantics of inline function static data `const |
| 7827 | unsigned char translate_table[262]' are wrong (you'll wind up with |
| 7828 | multiple copies)". |
| 7829 | |
| 7830 | * lib/bbitset.h (struct bitset_vtable): Rename members not, and, |
| 7831 | or, xor to not_, and_, or_, and xor_, respectively. This works |
| 7832 | around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a |
| 7833 | random system header somewhere that includes the equivalent of |
| 7834 | <iso646.h>. |

| 7841 | |
| 7842 | During deterministic GLR operation, user actions should be able to |
| 7843 | influence the parse by changing yychar. To make this easier to fix and |
| 7844 | to make glr.c easier to evolve in general, don't maintain yytoken in |
| 7845 | parallel with yychar; just compute yytoken when needed. |
| 7846 | * tests/glr-regression.at (Incorrect lookahead during deterministic |
| 7847 | GLR): Check that setting yychar in a user action has the intended |
| 7848 | effect. |
| 7849 | * data/glr.c (yyGLRStack): Remove yytokenp member. |
| 7850 | (yyclearin): Don't set *yytokenp. |
| 7851 | (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine |
| 7852 | yychar rather than *yytokenp to determine the current lookahead. |
| 7853 | Compute yytoken locally when needed. |
| 7854 | (yyparse): Likewise. Remove the local yytoken that yytokenp used to |
| 7855 | point to. |
| 7856 | |
| 7857 | * doc/bison.texinfo (Bison Options): Remove stray sentence fragment |
| 7858 | after `--report' documentation. |

| 7862 | * src/parse-gram.y (grammar_declaration): Location of printer |
| 7863 | symbol is @1, not list->location. Bug reported by twlevo. |
| 7864 | * tests/input.at (Incompatible Aliases): Adjust to above change. |
| 7865 | |
| 7866 | 2006-01-29 Paul Eggert <eggert@cs.ucla.edu> |
| 7867 | |
| 7868 | * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do |
| 7869 | all the test at once. This makes the output easier to read in the |
| 7870 | normal case. |
| 7871 | |
| 7872 | Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I |
| 7873 | got from <http://bro-ids.org/download.html>. The bug is that |
| 7874 | when two actions appeared in succession, the second one was |
| 7875 | scanned before the first one was added to the grammar rule |
| 7876 | as a midrule action. Bison then output the incorrect warning |
| 7877 | "parse.y:905.17-906.36: warning: unused value: $3". |
| 7878 | * src/parse-gram.y (BRACED_CODE, action): These are no longer |
| 7879 | associated with a value. |
| 7880 | (rhs): Don't invoke grammar_current_rule_action_append. |
| 7881 | (action): Invoke it here instead. |
| 7882 | * src/reader.c (grammar_midrule_action): Now extern. |
| 7883 | (grammar_current_rule_action_append): Don't invoke |
| 7884 | grammar_midrule_action; that is now the scanner's job. |
| 7885 | * src/reader.h (last_string, last_braced_code_loc): |
| 7886 | (grammar_midrule_action): New decls. |
| 7887 | * src/scan-gram.l (last_string): Now extern, sigh. |
| 7888 | (last_braced_code_loc): New extern variable. |
| 7889 | (<INITIAL>"{"): Invoke grammar_midrule_action if the current |
| 7890 | rule already has an action. |
| 7891 | (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning. |
| 7892 | * tests/input.at (AT_CHECK_UNUSED_VALUES): |
| 7893 | Add some tests to check that the above changes fixed the bug. |
| 7894 | |
| 7895 | 2006-01-27 Paul Eggert <eggert@cs.ucla.edu> |
| 7896 | |
| 7897 | * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p. |
| 7898 | All used changed. Check whether the symbol has a destructor, |
| 7899 | not whether it is typed. |
| 7900 | * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so |
| 7901 | that the values are still reported as unused. All line numbers |
| 7902 | adjusted. |
| 7903 | |
| 7904 | 2006-01-23 Paul Eggert <eggert@cs.ucla.edu> |

| 7906 | Work around a bug in bro 0.8, which underparenthesizes its |
| 7907 | definition of YYLLOC_DEFAULT. |

| 7909 | their arguments. |
| 7910 | * data/lalr1.cc: Likewise. |
| 7911 | * data/yacc.cc: Likewise. |

| 7914 | |
| 7915 | Work around a bug in Pike 7.0, and give the Pike folks a |
| 7916 | better way to override the usual int widths. |
| 7917 | * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the |
| 7918 | user can override the types. |
| 7919 | (short): #undef, to work around a bug in Pike 7.0. |
| 7920 | (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types. |
| 7921 | (union yyalloc.yyss): Use yytype_int16 rather than short. |
| 7922 | All uses changed. |
| 7923 | (yysigned_char): Remove. |
| 7924 | * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16): |
| 7925 | (YYTYPE_INT16): New macros, to test the new facility in yacc.c. |
| 7926 | * tests/regression.at (Web2c Actions): Adjust to above changes. |
| 7927 | |
| 7928 | * src/reader.c (check_and_convert_grammar): New function. |
| 7929 | (reader): Close the input file even if something went wrong during |
| 7930 | parsing. Minor file descriptor leak reported by twlevo. |
| 7931 | |
| 7932 | * src/assoc.c (assoc_to_string): Use a default: abort (); case |
| 7933 | to pacify gcc -Wswitch-default. |
| 7934 | * src/scan-gram.l (adjust_location): Use a default: break; case |
| 7935 | to pacify gcc -Wswitch-default. |
| 7936 | * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out): |
| 7937 | (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in): |
| 7938 | (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy): |
| 7939 | Move these decls to scan-skel.l, since they don't need to be |
| 7940 | visible elsewhere. |
| 7941 | * src/scan-skel.l: Accept the above decls. |
| 7942 | (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31 |
| 7943 | is used. |
| 7944 | |
| 7945 | 2006-01-21 Paul Eggert <eggert@cs.ucla.edu> |
| 7946 | |
| 7947 | * Makefile.cfg (local-checks-to-skip): Add changelog-check, |
| 7948 | since we don't want to insist on a version number at the start |
| 7949 | of the changelog every time. |
| 7950 | * Makefile.maint: Sync from coreutils a bit better. |
| 7951 | (sc_trailing_blank): Renamed from sc_trailing_space. |
| 7952 | All uses changed. |
| 7953 | (sc_no_if_have_config_h, sc_require_config_h): |
| 7954 | (sc_prohibit_assert_without_use): New rules. |
| 7955 | (sc_obsolete_symbols): Don't catch Makefile.maint itself. |
| 7956 | (sc_dd_max_sym_length): Fix leading spaces in rule. |
| 7957 | (sc_system_h_headers): Prefix with @. |
| 7958 | (sc_useless_cpp_parens, m4-check): Output line numbers. |
| 7959 | (changelog-check): Allow version only in head. |

| 8117 | yylookaheadNeeds. All uses updated. |
| 8118 | (yysplitStack): Rename local yynewLookaheadStatuses to |
| 8119 | yynewLookaheadNeeds. |
| 8120 | * data/glr-regression.at (Incorrect lookahead during nondeterministic |
| 8121 | GLR): In comments, change `lookahead status' to `lookahead need'. |

| 8132 | |
| 8133 | * doc/bison.texinfo: Fix some typos. |

| 8136 | (Actions): Mention look-ahead usage of yylval. |
| 8137 | (Actions and Locations): Mention look-ahead usage of yylloc. |
| 8138 | (Special Features for Use in Actions): Add YYEOF entry and mention it |
| 8139 | in the yychar entry. |
| 8140 | In the yychar entry, remove mention of the local yychar case (pure |
| 8141 | parser) since this is irrelevant information when writing semantic |
| 8142 | actions and since it's already discussed in `Table of Symbols' where |
| 8143 | yychar is otherwise described as an external variable. |
| 8144 | In the yychar entry, don't call it the `current' look-ahead since it |
| 8145 | isn't when semantic actions are deferred. |
| 8146 | In the yychar and yyclearin entries, add note about deferred semantic |
| 8147 | actions. |
| 8148 | Add yylloc and yylval entries discussing look-ahead usage. |
| 8149 | (Look-Ahead Tokens): When discussing yychar, don't call it the |
| 8150 | `current' look-ahead, and do mention yylval and yylloc. |
| 8151 | (Error Recovery): Cross-reference `Action Features' when mentioning |
| 8152 | yyclearin. |
| 8153 | (Table of Symbols): In the yychar entry, don't call it the `current' |
| 8154 | look-ahead. |
| 8155 | In the yylloc and yylval entries, mention look-ahead usage. |
| 8156 | |
| 8157 | 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu> |
| 8158 | |
| 8159 | * tests/glr-regression.at: Update copyright year to 2006. |
| 8160 | |
| 8161 | 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 8162 | |
| 8163 | * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to |
| 8164 | use during nondeterministic operation to track which stacks have |
| 8165 | actually needed the current lookahead. |
| 8166 | (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack): |
| 8167 | Allocate, deallocate, resize, and otherwise shuffle space for |
| 8168 | yylookaheadStatuses in parallel with yystates member of yyGLRStateSet. |
| 8169 | (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status |
| 8170 | appropriately during nondeterministic operation. |
| 8171 | (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc |
| 8172 | members to store the current lookahead to be used by the deferred |
| 8173 | user action. |
| 8174 | (yyaddDeferredAction): Add size_t yyk parameter specifying the stack |
| 8175 | from which the RHS is taken. Set the lookahead members of the new |
| 8176 | yySemanticOption according to the lookahead status for stack yyk. |
| 8177 | (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to |
| 8178 | yyaddDeferredAction. |
| 8179 | (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead |
| 8180 | members of yySemanticOption before invoking yyuserAction, and then set |
| 8181 | them back to their current values afterward. |
| 8182 | (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY. |
| 8183 | (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint. |
| 8184 | * tests/glr-regression.at: Remove `.' from the ends of recent test case |
| 8185 | titles for consistency. |
| 8186 | (Leaked merged semantic value if user action cuts parse): In order to |
| 8187 | suppress lint warnings, use arguments in merge function, and assign |
| 8188 | char value < 128 in main. |
| 8189 | (Incorrect lookahead during deterministic GLR): New test case. |
| 8190 | (Incorrect lookahead during nondeterministic GLR): New test case. |
| 8191 | |
| 8192 | 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 8193 | |
| 8194 | * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept |
| 8195 | !yyvaluep as signal that no semantic value is available to print. |
| 8196 | * data/glr.c (yydestroyGLRState): If state is not resolved, don't try |
| 8197 | to print a semantic value. |
| 8198 | |
| 8199 | 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu> |
| 8200 | |
| 8201 | * tests/glr-regression.at: For consistency with my newer test cases, |
| 8202 | don't thank myself. |
| 8203 | |
| 8204 | 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu> |
| 8205 | |
| 8206 | * data/glr.c (yyresolveValue): When merging semantic options, if at |
| 8207 | least one user action succeeds but a later one cuts the parse, then |
| 8208 | destroy the semantic value before returning rather than leaking it. |
| 8209 | (yyresolveStates): If a user action cuts the parse and thus |
| 8210 | yyresolveValue fails, ignore the (unset) semantic value rather than |
| 8211 | corrupting the yyGLRState, and empty the semantic options list since |
| 8212 | the user actions should have called all necessary destructors. |
| 8213 | Simplify code with YYCHK. |
| 8214 | * tests/glr-regression.at (Corrupted semantic options if user action |
| 8215 | cuts parse): New test case. |
| 8216 | (Undesirable destructors if user action cuts parse): New test case. |
| 8217 | Before applying any of this patch, this test case never actually failed |
| 8218 | for me... but only because the corrupted semantic options usually |
| 8219 | masked this bug. |
| 8220 | (Leaked merged semantic value if user action cuts parse): New test |
| 8221 | case. |
| 8222 | |
| 8223 | 2006-01-05 Akim Demaille <akim@epita.fr> |

| 8231 | (b4_c_function_def): Use it. |
| 8232 | * data/yacc.c (YYMODERN_C): Remove. All uses replaced by |
| 8233 | b4_c_modern. |
| 8234 | (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather |
| 8235 | than rolling our own. |
| 8236 | |
| 8237 | 2006-01-04 Akim Demaille <akim@epita.fr> |

| 8247 | * tests/input.at (AT_CHECK_UNUSED_VALUES): New. |
| 8248 | Use it. |
| 8249 | * tests/actions.at (Exotic Dollars): Adjust. |
| 8250 | |
| 8251 | 2006-01-04 Akim Demaille <akim@epita.fr> |
| 8252 | |

| 8257 | |
| 8258 | 2006-01-03 Paul Eggert <eggert@cs.ucla.edu> |
| 8259 | |
| 8260 | * doc/bison.texinfo (Bison Options): Say more accurately what |
| 8261 | --yacc does. |
| 8262 | * src/parse-gram.y (rules_or_grammar_declaration): Don't complain |
| 8263 | about declarations in the grammar when in Yacc mode, as POSIX does |
| 8264 | not require a diagnostic when the grammar uses extensions. |
| 8265 | |
| 8266 | * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool. |
| 8267 | |
| 8268 | Warn about dubious constructions like "%token T T". |
| 8269 | Reported by twlevo. |
| 8270 | * src/symtab.h (struct symbol.declared): New member. |
| 8271 | * src/symtab.c (symbol_new): Initialize it to false. |
| 8272 | (symbol_class_set): New arg DECLARING, specifying whether |
| 8273 | this is a declaration that we want to warn about, if there |
| 8274 | is more than one of them. All uses changed. |
| 8275 | |
| 8276 | * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c: |
| 8277 | Allow multiple %union directives, whose contents concatenate. |
| 8278 | * src/parse-gram.y (grammar_declaration): Likewise. |
| 8279 | Use muscle_code_grow, so that we don't need stype_line any more. |
| 8280 | All uses changed. |
| 8281 | |
| 8282 | * src/muscle_tab.c (muscle_grow): Fix comment. |
| 8283 | |

| 8298 | (b4_global_tokens_and_yystype): Honor it. |
| 8299 | * data/location.cc (c++.m4): Don't include it. |
| 8300 | * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF |
| 8301 | and AT_SKEL_CC_IF. |
| 8302 | * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of |
| 8303 | AT_LALR1_CC_IF. |
| 8304 | Be sure to initialize the first position's filename. |
| 8305 | (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are |
| 8306 | mandated anyway. |

| 8687 | |
| 8688 | * data/lalr1.cc: Move the body of the ctor and dtor into the |
| 8689 | parser file (instead of the header). |
| 8690 | Wrap the implementations in a "namespace yy". |
| 8691 | |
| 8692 | 2005-11-12 Akim Demaille <akim@epita.fr> |
| 8693 | |

| 8756 | 2005-10-30 Paul Eggert <eggert@cs.ucla.edu> |
| 8757 | |
| 8758 | * bootstrap (cleanup_gnulib): New function. Use it to clean up |
| 8759 | gnulib when interrupted. This fixes some race conditions and |
| 8760 | works around some portability problems (one noted by Paul |
| 8761 | Hilfinger). |
| 8762 | |
| 8763 | 2005-10-22 Akim <akim@epita.fr> |
| 8764 | |

| 8786 | |
| 8787 | 2005-10-14 Akim Demaille <akim@epita.fr> |
| 8788 | |
| 8789 | * examples/calc++/test: Use set -x only when VERBOSE. |

| 8799 | header file names. |
| 8800 | * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and |
| 8801 | additional checks. |
| 8802 | Use this to exercise C++ outputs in subdirs. |
| 8803 | Reported by Oleg Smolsky. |
| 8804 | |
| 8805 | 2005-10-12 Paul Eggert <eggert@cs.ucla.edu> |
| 8806 | |
| 8807 | * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at |
| 8808 | __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either. |
| 8809 | Problem reported by John P. Hartmann. |
| 8810 | * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has |
| 8811 | already defined it. |
| 8812 | |
| 8813 | 2005-10-12 Akim Demaille <akim@epita.fr> |
| 8814 | |
| 8815 | * src/parse-gram.y (version_check): Exit 63 to please missing |

| 8822 | (xlc and xlC_r) reported by John P. Hartmann. |
| 8823 | * data/location.cc (initial_column, initial_line): Remove. |
| 8824 | All uses replaced by 0 and 1. |
| 8825 | * src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31 |
| 8826 | that xlc complains about. |

| 8845 | (YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT): |
| 8846 | (YYCHK1): |

| 8848 | * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT): |
| 8849 | (YY_STACK_PRINT): Use 'false' not '0'. |

| 8862 | |
| 8863 | Undo the parts of the unlocked-I/O change that substituted |
| 8864 | putc or puts for printf. This might hurt performance a bit, |
| 8865 | but some people prefer the printf style. |
| 8866 | * data/c.m4 (yysymprint): Prefer printf to puts and putc. |
| 8867 | * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove. |
| 8868 | All uses replaced by YYFPRINTF and YYDPRINTF. |

| 8888 | unused-variable warnings. |
| 8889 | |

| 8893 | |
| 8894 | 2005-10-02 Paul Eggert <eggert@cs.ucla.edu> |
| 8895 | |
| 8896 | Use unlocked I/O for a minor performance improvement on hosts like |
| 8897 | GNU/Linux and Solaris that support unlocked I/O. The basic idea |
| 8898 | is to use the gnlib unlocked-io module, and to prefer putc and |
| 8899 | puts to printf when either will work (since the latter doesn't |
| 8900 | come in an unlocked flavor). |
| 8901 | * bootstrap (gnulib_modules): Add unlocked-io. |
| 8902 | * data/c.m4 (yysymprint): Prefer puts and putc to printf. |
| 8903 | * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros. |

| 8905 | and similarly for puts and putc and printf. |
| 8906 | * data/yacc.c: Likewise. |
| 8907 | * lib/bitset.c (bitset_print): Likewise. |
| 8908 | * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h. |

| 8920 | * src/system.h: Include unlocked-io.h rather than stdio.h. |
| 8921 | |
| 8922 | * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as |
| 8923 | this confuses xgettext. |
| 8924 | |

| 8966 | |

| 9058 | |
| 9059 | * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Do not use |
| 9060 | local variables whose names begin with 'yy'. |
| 9061 | * tests/calc.at (_AT_DATA_CALC_Y): Likewise. |
| 9062 | Trivial changes from Joel E. Denny. |
| 9063 | |
| 9064 | * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need |
| 9065 | it itself. |
| 9066 | * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we |
| 9067 | don't use alloca any more. |
| 9068 | |
| 9069 | * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined |
| 9070 | __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER && |
| 9071 | defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case. |
| 9072 | * tests/torture.at (Exploding the Stack Size with Alloca): Adjust |
| 9073 | to match yacc.c, to test more hosts. |
| 9074 | |
| 9075 | 2005-09-20 Paul Eggert <eggert@cs.ucla.edu> |
| 9076 | |
| 9077 | * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This |
| 9078 | doesn't affect behavior. |
| 9079 | (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for |
| 9080 | Solaris, AIX, MSC. |
| 9081 | (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed. |
| 9082 | This works a bit better with glibc, if user code has already included |
| 9083 | stdlib.h. |
| 9084 | * doc/bison.texinfo (Bison Parser): Document that users can't |
| 9085 | arbitrarily use malloc and free for other purposes. Document |
| 9086 | that <alloca.h> and <malloc.h> might be included. |
| 9087 | (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the |
| 9088 | user must declare alloca. |
| 9089 | |
| 9090 | * HACKING (release): Forwarn the Translation Project about |
| 9091 | stable releses. |
| 9092 | |
| 9093 | 2005-09-20 Akim Demaille <akim@epita.fr> |
| 9094 | |
| 9095 | * data/glr.c: Use b4_token_enums, not b4_token_enums_defines. |
| 9096 | |
| 9097 | 2005-09-19 Paul Eggert <eggert@cs.ucla.edu> |
| 9098 | |
| 9099 | * data/yacc.c (YYSIZE_MAXIMUM): New macro. |
| 9100 | (YYSTACK_ALLOC_MAXIMUM): Use it. |
| 9101 | (yysyntax_error): New function. |
| 9102 | (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if |
| 9103 | multiple syntax errors are reported, and alloca is being used. |
| 9104 | Instead, reallocate buffers twice as big each time, so that |
| 9105 | we waste at most half the allocated memory. Start with a small |
| 9106 | (128-byte) buffer that will suffice in most cases anyway. |
| 9107 | Use yysyntax_error to do most of the work. |
| 9108 | |
| 9109 | * doc/bison.texinfo (Error Reporting, Table of Symbols): |
| 9110 | yynerrs is the number of errors reported, not the number of |
| 9111 | errors encountered. |
| 9112 | |
| 9113 | * tests/glr-regression.at (Duplicated user destructor for lookahead): |
| 9114 | Mark it as expected to fail. |
| 9115 | Cast result of malloc; problem reported by twlevo@xs4all.nl. |
| 9116 | * tests/actions.at, tests/calc.at, tests/glr-regression.at: |
| 9117 | Don't start user-code symbols with "yy", to avoid name space problems. |
| 9118 | |
| 9119 | 2005-09-19 Akim Demaille <akim@epita.fr> |
| 9120 | |
| 9121 | Remove the traits, failed experiment. |
| 9122 | It never proved useful, and anyway because of the current |
| 9123 | definition, it was not possible to have several specialization of |
| 9124 | this traits, making it useless. |
| 9125 | * data/lalr1.cc (yy:traits): Remove. |
| 9126 | Inline its definitions in the parser class. |
| 9127 | |
| 9128 | 2005-09-19 Akim Demaille <akim@epita.fr> |
| 9129 | |
| 9130 | * tests/atlocal.in (LIBS): Pass INTLLIBS to address failures on at |
| 9131 | least Mac OSX with a /usr/local install of gettext. |
| 9132 | |
| 9133 | 2005-09-19 Akim Demaille <akim@epita.fr> |
| 9134 | |
| 9135 | * data/lalr1.cc (yyparse): Rename yylooka and yyilooka as yychar |
| 9136 | and yytoken for similarity with the other skeletons. |
| 9137 | |
| 9138 | 2005-09-19 Akim Demaille <akim@epita.fr> |
| 9139 | |
| 9140 | * NEWS, configure.ac: update version number to 2.1a. |
| 9141 | |
| 9142 | 2005-09-16 Paul Eggert <eggert@cs.ucla.edu> |
| 9143 | |
| 9144 | * NEWS: Version 2.1. |
| 9145 | |
| 9146 | * NEWS: Remove notice of yytname change, since it was never in an |
| 9147 | official release. |
| 9148 | * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing |
| 9149 | diagnostic. |
| 9150 | * src/output.c (prepare): Likewise. |
| 9151 | * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro. |
| 9152 | (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE |
| 9153 | is not defined. This is an awful hack, but it's enough for now. |
| 9154 | All callers changed. |
| 9155 | * tests/glr-regression-at (make_value): Args are const pointers now, |
| 9156 | to avoid GCC warning. |
| 9157 | (Duplicated user destructor for lookahead): New test. Currently |
| 9158 | skipped. It fails on my host but I'm not sure it'll always fail. |
| 9159 | |
| 9160 | 2005-09-16 Akim Demaille <akim@epita.fr> |
| 9161 | |
| 9162 | * src/symtab.h (struct symbol): Declare the printer and destructor |
| 9163 | as const, to avoid accidental calls to free. |
| 9164 | (symbol_destructor_set, symbol_printer_set): Adjust. |
| 9165 | * src/symtab.c: Adjust. |
| 9166 | |
| 9167 | 2005-09-16 Akim Demaille <akim@epita.fr> |
| 9168 | |
| 9169 | * data/c.m4 (b4_token_enums): New. |
| 9170 | (b4_token_defines): Rename as... |
| 9171 | (b4_token_enums_defines): this. |
| 9172 | (b4_token_defines): New, output only the #defines. |
| 9173 | * data/yacc.c, data/glr.c: Adjust. |
| 9174 | * data/lalr1.cc: Use b4_token_enums instead of b4_token_enums_defines. |
| 9175 | * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate): Define |
| 9176 | as default values. |
| 9177 | |
| 9178 | 2005-09-16 Akim Demaille <akim@epita.fr> |
| 9179 | |
| 9180 | * data/lalr1.cc (yylex_): Remove, inline its code. |
| 9181 | (yyreport_syntax_error_): Remove, replaced by... |
| 9182 | (yysyntax_error_): this which returns a string and leaves to the |
| 9183 | caller the call to the users' error function. |
| 9184 | (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc): |
| 9185 | Move from members of the parser object... |
| 9186 | (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc): |
| 9187 | to local variables of the parse function. |
| 9188 | |
| 9189 | 2005-09-16 Akim Demaille <akim@epita.fr> |
| 9190 | |
| 9191 | * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF |
| 9192 | since it's in Bison's name space. |
| 9193 | |
| 9194 | 2005-09-15 Paul Eggert <eggert@cs.ucla.edu> |
| 9195 | |
| 9196 | * data/glr.c (yyresolveValue): Add default case to pacify |
| 9197 | gcc -Wswitch-default. Problem reported by twlevo@xs4all.nl. |
| 9198 | |
| 9199 | * NEWS: Document when yyparse started to return 2. |
| 9200 | * doc/bison.texinfo (Parser Function): Document when yyparse |
| 9201 | returns 2. |
| 9202 | |
| 9203 | * data/lalr1.cc: Revert part of previous change, as it's incompatible. |
| 9204 | (b4_filename_type): Renamed back from b4_file_name_type. All uses |
| 9205 | changed. |
| 9206 | (class position): file_name -> filename (reverting). All uses changed. |
| 9207 | |
| 9208 | 2005-09-14 Paul Eggert <eggert@cs.ucla.edu> |
| 9209 | |
| 9210 | * examples/calc++/Makefile.am ($(calc_sources_generated)): Don't |
| 9211 | do anything if $@ exists. This reverts part of the 2005-07-07 |
| 9212 | patch. |
| 9213 | |
| 9214 | 2005-09-11 Paul Eggert <eggert@cs.ucla.edu> |
| 9215 | |
| 9216 | * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it |
| 9217 | contains obsolete information and isn't worth distributing as a |
| 9218 | separate file anyway. |
| 9219 | * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>. |
| 9220 | (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros. |
| 9221 | All uses of jmp_buf, setjmp, longjmp changed to use these instead. |
| 9222 | (yyparse): Abort if user code uses longjmp to throw an unexpected |
| 9223 | value. |
| 9224 | |
| 9225 | 2005-09-09 Paul Eggert <eggert@cs.ucla.edu> |
| 9226 | |
| 9227 | * data/c.m4 (b4_identification): Define YYBISON_VERSION. |
| 9228 | Suggested by twlevo@xs4all.nl. |
| 9229 | |
| 9230 | * data/glr.c (YYCHK1): Do not assume YYE is in range. |
| 9231 | This avoids a diagnostic from gcc -Wswitch-enum. |
| 9232 | Problem reported by twlevo@xs4all.nl. |
| 9233 | |
| 9234 | * doc/bison.texinfo: Don't use "filename", as per GNU coding |
| 9235 | standards. Use "file name" or "file" or "name", depending on |
| 9236 | the context. |
| 9237 | (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c, |
| 9238 | not to hack/foo.tab.c. |
| 9239 | (Calc++ Top Level): 2nd arg of main is not const. |
| 9240 | * data/glr.c: b4_filename -> b4_file_name. |
| 9241 | * data/lalr1.cc: Likewise. Also, b4_filename_type -> b4_file_name_type. |
| 9242 | All uses changed. |
| 9243 | (class position): filename -> file_name. All uses changed. |
| 9244 | * data/yacc.c: b4_filename -> b4_file_name. |
| 9245 | * lib/bitset.h: filename -> file_name in local vars. |
| 9246 | * lib/bitset_stats.c: Likewise. |
| 9247 | * src/files.c: Likewise. |
| 9248 | * src/scan-skel.l ("@output ".*\n): Likewise. |
| 9249 | * src/files.c (file_name_split): Renamed from filename_split. |
| 9250 | * src/muscle_tab.c (muscle_init): Output b4_file_name, not b4_filename. |
| 9251 | |
| 9252 | 2005-09-08 Paul Eggert <eggert@cs.ucla.edu> |
| 9253 | |
| 9254 | * lib/.cvsignore: Add pipe-safer.c, stdio--.h, unistd--.h, |
| 9255 | to accommodate latest gnulib. |
| 9256 | |
| 9257 | * tests/glr-regression.at (Duplicate representation of merged trees): |
| 9258 | Add casts to pacify g++. Problem reported by twlevo@xs4all.nl. |
| 9259 | |
| 9260 | * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is |
| 9261 | needed. |
| 9262 | |
| 9263 | 2005-08-26 Paul Eggert <eggert@cs.ucla.edu> |
| 9264 | |
| 9265 | * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem. |
| 9266 | All uses changed. Invoke user destructor after an error during a |
| 9267 | split parse (trivial change from Joel E. Denny). |
| 9268 | |
| 9269 | * tests/glr-regression.at |
| 9270 | (User destructor after an error during a split parse): New test case. |
| 9271 | Problem reported by Joel E. Denny in: |
| 9272 | http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html |
| 9273 | |
| 9274 | 2005-08-25 Paul Eggert <eggert@cs.ucla.edu> |
| 9275 | |
| 9276 | * README-cvs: Give URLs for recommended tools. |
| 9277 | Mention Gzip version problem, and bootstrapping issues. |
| 9278 | Remove troubleshooting section, as it's somewhat obsolete. |
| 9279 | |
| 9280 | * bootstrap (no_cache): New var, to accommodate different wget |
| 9281 | variants. Use it instead of '-C off'. Problem reported by |
| 9282 | twlevo@xs4all.nl. |
| 9283 | |
| 9284 | * data/glr.c (yydestroyStackItem): New function. |
| 9285 | (yyrecoverSyntaxError, yyreturn): Use it to improve quality of |
| 9286 | debugging information. Problem reported by Joel E. Denny. |
| 9287 | |
| 9288 | 2005-08-25 Akim Demaille <akim@epita.fr> |
| 9289 | |
| 9290 | * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too. |
| 9291 | |
| 9292 | 2005-08-24 Paul Eggert <eggert@cs.ucla.edu> |
| 9293 | |
| 9294 | * data/glr.c (yyrecoverSyntaxError, yyreturn): |
| 9295 | Don't invoke destructor on unresolved entries. |
| 9296 | * tests/glr-regression.at |
| 9297 | (User destructor for unresolved GLR semantic value): New test case. |
| 9298 | Problem reported by Joel E. Denny in: |
| 9299 | http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html |
| 9300 | |
| 9301 | 2005-08-21 Paul Eggert <eggert@cs.ucla.edu> |
| 9302 | |
| 9303 | * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c. |
| 9304 | Add strnlen.c. |
| 9305 | * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4, |
| 9306 | lib-prefix.m4, po.m4. |
| 9307 | |
| 9308 | * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:" |
| 9309 | in yydestruct diagnostic, since it might not be an error. |
| 9310 | Problem reported by Joel Denny near end of |
| 9311 | <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>. |
| 9312 | * data/lalr1.cc (yyerturn): Likewise. |
| 9313 | * data/yacc.c (yyreturn): Likewise. |
| 9314 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change. |
| 9315 | |
| 9316 | * src/files.c: Remove obsolete FIXME comment. |
| 9317 | |
| 9318 | * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency |
| 9319 | with the other templates, and to fix bogus run-on messages such |
| 9320 | as the one reported at the end of |
| 9321 | <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>. |
| 9322 | All callers changed to avoid the newline. |
| 9323 | (yyprocessOneStack): Output two lines rather than one, to accommodate |
| 9324 | the above change. This changes the debug output format slightly. |
| 9325 | |
| 9326 | * data/glr.c (yyresolveValue): Fix redundant parse tree problem |
| 9327 | reported by Joel E. Denny in |
| 9328 | <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html> |
| 9329 | (trivial change). |
| 9330 | * tests/glr-regression.at (Duplicate representation of merged trees): |
| 9331 | New test, from Joel E. Denny in: |
| 9332 | <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>. |
| 9333 | * THANKS: Add Joel E. Denny. |
| 9334 | |
| 9335 | * configure.ac (AC_INIT): Bump to 2.0c. |
| 9336 | |
| 9337 | 2005-07-24 Paul Eggert <eggert@cs.ucla.edu> |
| 9338 | |
| 9339 | * NEWS: Version 2.0b. |
| 9340 | |
| 9341 | * Makefile.am (SUBDIRS): Put examples before tests, so that |
| 9342 | "make check" doesn't finish with "All 1 tests passed". |
| 9343 | |
| 9344 | * tests/regression.at (Token definitions): Don't rely on |
| 9345 | AT_PARSER_CHECK for data that contains backslashes. It currently |
| 9346 | uses 'echo', and 'echo' isn't portable if its argument contains |
| 9347 | backslashes. Problem found on OpenBSD 3.4. Also, do not assume |
| 9348 | that the byte '\0xff' is not printable in the C locale; it is, |
| 9349 | under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are |
| 9350 | not printable, so use '\0x81' to test. |
| 9351 | |
| 9352 | * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent |
| 9353 | version of GCC, since the macro is used with non-GCC compilers. |
| 9354 | |
| 9355 | Fix core dump reported by Pablo De Napoli in |
| 9356 | <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>. |
| 9357 | * tests/regression.at (Invalid inputs with {}): New test. |
| 9358 | * src/parse-gram.y (token_name): Translate type before using |
| 9359 | it as an index. |
| 9360 | |
| 9361 | * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on |
| 9362 | the user's name space. All uses changed to __attribute__ |
| 9363 | ((__unused__)). |
| 9364 | (yyFail, yyMemoryExhausted, yyreportAmbiguity): |
| 9365 | Add __attribute__ ((__noreturn__)). |
| 9366 | |
| 9367 | * etc/clcommit: Remove. We weren't using it, and it failed |
| 9368 | "make maintainer-distcheck". |
| 9369 | * Makefile.maint: Merge from coreutils. |
| 9370 | (CVS_LIST, CVS_LIST_EXCEPT): New macros. |
| 9371 | (syntax-check-rules): Change list of rules as described below. |
| 9372 | (sc_cast_of_alloca_return_value, sc_dd_max_sym_length): |
| 9373 | (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof): |
| 9374 | (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope): |
| 9375 | (sc_trailing_space): New rules. |
| 9376 | (sc_xalloc_h_in_src): Remove. |
| 9377 | (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value): |
| 9378 | (sc_space_tab, sc_error_exit_success, sc_changelog): |
| 9379 | (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics): |
| 9380 | (makefile-check, po-check, author_mark_check): |
| 9381 | (makefile_path_separator_check, copyright-check): |
| 9382 | Use grep -n, to make it easier to find violations. |
| 9383 | Use CVS_LIST and CVS_LIST_EXCEPT. |
| 9384 | (header_regexp, h_re): Remove. |
| 9385 | (dd_c): New macro. |
| 9386 | (sc_dd_max_sym_length, .re-list, news-date-check): New rules. |
| 9387 | (my-distcheck): Use more-modern GCC flags. |
| 9388 | (signatures, %.asc): Remove. |
| 9389 | (rel-files, announcement): Remove signatures. |
| 9390 | Restore old updating code, even though we don't use it, so |
| 9391 | that we're the same as coreutils. |
| 9392 | (alpha, beta, major): Depend on news-date-check. |
| 9393 | Make the upload commands. |
| 9394 | |
| 9395 | * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space. |
| 9396 | * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise. |
| 9397 | * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise. |
| 9398 | * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise. |
| 9399 | * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise. |
| 9400 | * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise. |
| 9401 | * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise. |
| 9402 | * tests/sets.at: Likewise. |
| 9403 | |
| 9404 | * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that |
| 9405 | we comment out the Autoconf version number. |
| 9406 | * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as |
| 9407 | it's error-prone and "make maintainer-distcheck" rejects it. |
| 9408 | |
| 9409 | * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H. |
| 9410 | Indent calls to "error" to pacify "make maintainer-distcheck", |
| 9411 | when the calls are not intended to be translated. |
| 9412 | * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h. |
| 9413 | |
| 9414 | * src/Makefile.am (DEFS): Use +=, to pacify |
| 9415 | "make maintainer-distcheck". |
| 9416 | (bison_SOURCES): Add scan-skel.h. |
| 9417 | (sc_tight_scope): New rule, from coreutils. |
| 9418 | |
| 9419 | * src/files.c (src_extension, header_extension): |
| 9420 | Now static, not extern. |
| 9421 | * src/getargs.c (short_options): Likewise. |
| 9422 | * src/muscle_tab.c (muscle_table): Likewise. |
| 9423 | * src/parse-gram.y (current_class, current_type, current_prec): |
| 9424 | Likewise. |
| 9425 | * src/reader.c (grammar_end, previous_rule_end): Likewise. |
| 9426 | * src/getargs.h: Redo comments to pacify "make maintainer-distcheck". |
| 9427 | * src/main.c (main): Cast bindtextdomain and textdomain calls to |
| 9428 | void, to avoid warning when NLS is disabled. |
| 9429 | * src/output.c: Include scan-skel.h. |
| 9430 | (scan_skel): Remove decl, since scan-skel.h does this. |
| 9431 | (output_skeleton): |
| 9432 | Indent calls to "error" to pacify "make maintainer-distcheck". |
| 9433 | * src/print_graph.c: Don't include <obstack.h>, as system.h does this. |
| 9434 | * src/reader.h (gram_end, gram_lineno): New decls to pacify |
| 9435 | "make maintainer-distcheck". |
| 9436 | * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in): |
| 9437 | (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno): |
| 9438 | (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug): |
| 9439 | (skel_lex_destroy, scan_skel): Move these decls to... |
| 9440 | * src/scan-skel.h: New file. |
| 9441 | * src/uniqstr.c (uniqstr_assert): |
| 9442 | Indent calls to "error" to pacify "make maintainer-distcheck". |
| 9443 | |
| 9444 | * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR), |
| 9445 | not @VAR@. |
| 9446 | |
| 9447 | * tests/torture.at: Revamp to avoid misuse of atoi that |
| 9448 | "make maintainer-distcheck" complained about. |
| 9449 | |
| 9450 | * examples/extexi (message): Don't print a message more than once, |
| 9451 | and omit line-number decoration that makes Emacs compile think |
| 9452 | that informative messages are worth worrying about. |
| 9453 | |
| 9454 | 2005-07-22 Paul Eggert <eggert@cs.ucla.edu> |
| 9455 | |
| 9456 | * configure.ac: Update version number. |
| 9457 | |
| 9458 | * Makefile.am (SUBDIRS): Add examples; somehow this got removed |
| 9459 | accidentally. |
| 9460 | * examples/calc++/calc++-parser.yy: Remove from CVS, as it's |
| 9461 | autogenerated by the maintainer. |
| 9462 | * examples/calc++/.cvsignore: Add *.yy. |
| 9463 | |
| 9464 | * lib/bitset.c (bitset_alloc): Don't cast xcalloc result. |
| 9465 | * lib/bitset_stats.c (bitset_stats_init): Likewise. |
| 9466 | * lib/bitsetv.c (bitsetv_alloc): Likewise. |
| 9467 | |
| 9468 | * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c. |
| 9469 | |
| 9470 | * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint |
| 9471 | from maintainer-distcheck about casting the argument of 'free'. |
| 9472 | |
| 9473 | * NEWS: Mention recent yytname changes. |
| 9474 | * THANKS: Add Anthony Heading, twlevo@xs4all.nl. |
| 9475 | |
| 9476 | * bootstrap: For translations that have not yet been upgraded to |
| 9477 | the new runtime-po domain, prime the pump by extracting the |
| 9478 | relevant strings from the obsolete translations. This code can be |
| 9479 | removed once the bison-runtime domain has been translated by each |
| 9480 | team. |
| 9481 | |
| 9482 | * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names, |
| 9483 | now that token names are already quoted. |
| 9484 | |
| 9485 | Fix problem reported by Anthony Heading. |
| 9486 | * data/glr.c (YYTOKEN_TABLE): New macro. |
| 9487 | (yytname): Define if YYTOKEN_TABLE. |
| 9488 | * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise. |
| 9489 | * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise. |
| 9490 | (YYERROR_VERBOSE): Define the same way the other skeletons do. |
| 9491 | * src/output.c (prepare_symbols): Output token_table_flag. |
| 9492 | |
| 9493 | 2005-07-21 Paul Eggert <eggert@cs.ucla.edu> |
| 9494 | |
| 9495 | * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc |
| 9496 | again if the first call fails. |
| 9497 | |
| 9498 | * data/glr.c (yytnamerr): New function. |
| 9499 | (yyreportSyntaxError): Use it to dequote most string literals. |
| 9500 | * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility |
| 9501 | with other skeletons. All uses changed. |
| 9502 | (yytnameerr_): New function. |
| 9503 | (yyreport_syntax_error): Use it to dequote most string literals. |
| 9504 | * data/yacc.c (yytnamerr): New function. |
| 9505 | (yyerrlab): Use it to decode most string literals. |
| 9506 | * doc/bison.texinfo (Decl Summary, Calling Convention): |
| 9507 | Clarify quoting convention of yytname. |
| 9508 | * src/output.c (prepare_symbols): Quote all names. This undoes |
| 9509 | the 2005-04-17 change, which is now accomplished (mostly) via |
| 9510 | changes in the parsers as described above. |
| 9511 | * tests/regression.at (Token definitions, Web2c Actions): |
| 9512 | Undo most 2005-04-17 change here, too. |
| 9513 | |
| 9514 | 2005-07-20 Paul Eggert <eggert@cs.ucla.edu> |
| 9515 | |
| 9516 | Fix more problems reported by twlevo@xs4all.nl. |
| 9517 | * tests/cxx-type.at: Don't pipe output of ./types through sed to |
| 9518 | remove trailing spaces. This loses the exit status of ./types, |
| 9519 | and isn't needed since ./types shouldn't be emitting trailing |
| 9520 | spaces. |
| 9521 | * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed, |
| 9522 | as the stack isn't valid in that case. |
| 9523 | |
| 9524 | * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out): |
| 9525 | (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in): |
| 9526 | (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy): |
| 9527 | Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31 |
| 9528 | is used. |
| 9529 | * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out): |
| 9530 | (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in): |
| 9531 | (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy): |
| 9532 | Likewise. |
| 9533 | |
| 9534 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with |
| 9535 | overly-picky compilers that reject 'char *foo = "bar";'. |
| 9536 | |
| 9537 | * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output |
| 9538 | to FILE * parameter, not to stderr. This fixes a typo introduced |
| 9539 | in the 2005-07-12 change. |
| 9540 | |
| 9541 | * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid |
| 9542 | warnings from GCC 4. |
| 9543 | |
| 9544 | * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack): |
| 9545 | (yyglrShiftDefer, yysplitStack): |
| 9546 | Remove unused parameters b4_pure_formals. All uses changed. |
| 9547 | (yyglrShift): Remove unused parameters b4_user_formals. |
| 9548 | All uses changed. |
| 9549 | (yyglrReduce): Removed unused parameter yylocp. All uses changed. |
| 9550 | |
| 9551 | 2005-07-18 Paul Eggert <eggert@cs.ucla.edu> |
| 9552 | |
| 9553 | Destructor cleanups and regularization among the three skeletons. |
| 9554 | * NEWS: Document the behavior changes. |
| 9555 | * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the |
| 9556 | stack before failing, as the cleanup code will do it for us now. |
| 9557 | * data/lalr1.cc (yyerrlab): Likewise. |
| 9558 | * data/glr.c (yyparse): Pop everything off the stack before |
| 9559 | freeing it, so that destructors get called properly. |
| 9560 | * data/lalr1.cc (yyreturn): Likewise. |
| 9561 | * data/yacc.c (yyreturn): Pop and destroy the start symbol, too. |
| 9562 | This is more consistent. |
| 9563 | * doc/bison.texinfo (Destructor Decl): Mention more reasons |
| 9564 | why destructors might be called. 1.875 -> 2.1. |
| 9565 | (Destructor Decl, Decl Summary, Table of Symbols): |
| 9566 | Some English-language cleanups for %destructor. |
| 9567 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): |
| 9568 | Add output line for destructor of start symbol. |
| 9569 | * tests/calc.at (AT_CHECK_CALC): Add one to line counts, |
| 9570 | because of that same extra output line. |
| 9571 | |
| 9572 | * NEWS: Document minor wording changes in diagnostics of |
| 9573 | Bison-generated parsers. |
| 9574 | * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow. |
| 9575 | Remove unused formals. All uses changed. |
| 9576 | (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous". |
| 9577 | (yyparse): Rename yyoverflowlab to yyexhaustedlab. |
| 9578 | * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted". |
| 9579 | Rename yyoverflowab to yyexhaustedlab. |
| 9580 | When memory exhaustion occurs during syntax-error reporting, |
| 9581 | report it separately rather than in a single diagnostic; this |
| 9582 | eases translation. |
| 9583 | * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow. |
| 9584 | (Memory Exhausted): Renamed from Parser Stack Overflow. |
| 9585 | Revamp wording slightly to prefer "memory exhaustion". |
| 9586 | * tests/actions.at: "parser stack overflow" -> "memory exhausted". |
| 9587 | |
| 9588 | * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf. |
| 9589 | |
| 9590 | Add i18n support to the GLR skeleton. Partially fix the C++ |
| 9591 | skeleton; a C++ expert needs to finish this. Remove debugging |
| 9592 | msgids; there's little point to having them translated, since they |
| 9593 | can be understood only by someone who can read the |
| 9594 | (English-language) source code. |
| 9595 | |
| 9596 | Generate runtime-po/bison-runtime.pot automatically, so that we |
| 9597 | don't have to worry about garbage getting in that file. We'll |
| 9598 | make sure after the next official release that old msgids don't |
| 9599 | get lost. See |
| 9600 | <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>. |
| 9601 | |
| 9602 | * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove. |
| 9603 | Now auto-generated. |
| 9604 | * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet. |
| 9605 | Fix typos in explanations of the runtime file. |
| 9606 | * bootstrap: Change gettext keyword from YYI18N to YY_. |
| 9607 | Use standard Makefile.in.in in runtime-po, since we'll arrange |
| 9608 | for backward-compatible bison-runtime.po files in a different way. |
| 9609 | * data/glr.c (YY_): New macro, from yacc.c. |
| 9610 | (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse): |
| 9611 | Translate messages intended for users. |
| 9612 | (yyreportSyntaxError): Change "virtual memory" to "memory" to match |
| 9613 | the wording in the other skeletons. We don't know that the memory |
| 9614 | is virtual. |
| 9615 | * data/lalr1.cc (YY_): Renamed from _. All uses changed. |
| 9616 | Use same method that yacc.c uses. |
| 9617 | Don't translate debugging messages. |
| 9618 | (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff; |
| 9619 | it doesn't work (yet), and requires C++ expertise to fix. |
| 9620 | * data/yacc.c (YY_): Renamed from YY18N. All uses changed. |
| 9621 | Move defn to a more logical place, to be consistent with other |
| 9622 | skeletons. |
| 9623 | Don't translate debugging messages. |
| 9624 | Don't assume line numbers fit in unsigned int; use unsigned long fmts. |
| 9625 | * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference |
| 9626 | to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS. |
| 9627 | * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc. |
| 9628 | |
| 9629 | Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl. |
| 9630 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return |
| 9631 | void, not int. |
| 9632 | * tests/glr-regression.at (Badly Collapsed GLR States): |
| 9633 | Likewise. |
| 9634 | (Improper handling of embedded actions and dollar(-N) in GLR parsers): |
| 9635 | yylex should return 0 at EOF rather than aborting. |
| 9636 | |
| 9637 | Improve tests for stack overflow in GLR parser. |
| 9638 | Problem reported by twlevo@xs4all.nl. |
| 9639 | * data/glr.c (struct yyGLRStack): Remove yyerrflag member. |
| 9640 | All uses removed. |
| 9641 | (yyStackOverflow): Just longjmp, but with value 2 so that caller |
| 9642 | can handle the problem. |
| 9643 | (YYCHK1): Use goto (a la yacc.c) rather than setting a flag. |
| 9644 | (yyparse): New local variable yyresult to record the result. |
| 9645 | Use result of setjmp to set it, rather than storing itinto |
| 9646 | struct. |
| 9647 | (yyDone): Remove label. |
| 9648 | (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels, |
| 9649 | to mimic yacc.c. Do not discard lookahead if it's EOF (possible |
| 9650 | if YYABORT is used). |
| 9651 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with |
| 9652 | yyparse status; put status > 1 into diagnostic. |
| 9653 | Check that status==2 works. |
| 9654 | * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at: |
| 9655 | Use exit status 3 for failure to open (which shouldn't happen). |
| 9656 | |
| 9657 | 2005-07-17 Paul Eggert <eggert@cs.ucla.edu> |
| 9658 | |
| 9659 | * tests/conflicts.at (%nonassoc and eof): Don't exit with status |
| 9660 | 1 on syntax error; just let yyparse do its thing. |
| 9661 | * tests/glr-regression.at (Badly Collapsed GLR States): Likewise. |
| 9662 | * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise. |
| 9663 | (Exploding the Stack Size with Alloca): |
| 9664 | (Exploding the Stack Size with Malloc): |
| 9665 | Expect exit status 2, not 1, since the parser is supposed to blow |
| 9666 | its stack. Problem reported by twlevo@xs4all.nl. |
| 9667 | |
| 9668 | * data/glr.c (yyparse): Don't assume that the initial calls |
| 9669 | to YYMALLOC succeed; in that case, yyparse incorrectly returned 0. |
| 9670 | Print a stack-overflow message and fail instead. |
| 9671 | Initialize the line-number information before creating the stack, |
| 9672 | so that the stack-overflow message can report line zero safely. |
| 9673 | |
| 9674 | 2005-07-14 Paul Eggert <eggert@cs.ucla.edu> |
| 9675 | |
| 9676 | Fix problems reported by twlevo@xs4all.nl. |
| 9677 | * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined. |
| 9678 | (yyuserMerge): Provide a default case if b4_mergers is empty. |
| 9679 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE. |
| 9680 | * tests/glr-regression.at |
| 9681 | (Improper handling of embedded actions and dollar(-N) in GLR parsers): |
| 9682 | Add casts to pacify C++ compilers. |
| 9683 | * tests/glr-regression.at (Improper merging of GLR delayed action |
| 9684 | sets): Declare yylex before using it. |
| 9685 | * tests/Makefile.am (maintainer-check-g++): Fix a stray |
| 9686 | $(GXX) that escaped the renaming of GXX to CXX. Remove bogus |
| 9687 | test for valgrind; valgrind is independent of g++. |
| 9688 | (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check |
| 9689 | for compatibility with POSIX 1003.1-2001 (if running coreutils). |
| 9690 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++. |
| 9691 | Use a destructor, so that we can expand the stack. Change |
| 9692 | YYSTYPE to char * so that we can free it. Cast result of malloc. |
| 9693 | |
| 9694 | 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU> |
| 9695 | |
| 9696 | * data/glr.c (yyuserAction): Fix uninitialized variable that caused |
| 9697 | a valgrind failure. Problem reported by twlevo@xs4all.nl. |
| 9698 | |
| 9699 | 2005-07-13 Paul Eggert <eggert@cs.ucla.edu> |
| 9700 | |
| 9701 | * PACKAGING: New file, suggested by Bruno Haible and taken from |
| 9702 | similar wording in gettext's PACKAGING file. |
| 9703 | * NEWS: Mention PACKAGING. |
| 9704 | * Makefile.am (EXTRA_DIST): Add PACKAGING. |
| 9705 | |
| 9706 | 2005-07-12 Paul Eggert <eggert@cs.ucla.edu> |
| 9707 | |
| 9708 | * NEWS: Document recent i18n improvements. |
| 9709 | * bootstrap: Get runtime translations into runtime-po. |
| 9710 | Create runtime-po files automatically, if possible. |
| 9711 | * configure.ac: Invoke BISON_I18N, so that we eat our own dog food. |
| 9712 | * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS |
| 9713 | does not infringe on the user's name space. |
| 9714 | (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS. |
| 9715 | * doc/bison.texinfo (Internationalization): Revamp the English |
| 9716 | and Texinfo syntax a bit, to try to make it clearer. |
| 9717 | (Bison Options, Option Cross Key): Mention --print-localedir. |
| 9718 | * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to |
| 9719 | YYENABLE_NLS. Quote a bit more. |
| 9720 | * runtime-po/.cvsignore: New file. |
| 9721 | * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot. |
| 9722 | * runtime-po/Rules-quot: Remove; now created by bootstrap. |
| 9723 | * runtime-po/quot.sed: Likewise. |
| 9724 | * runtime-po/boldquot.sed: Likewise. |
| 9725 | * runtime-po/en@quot.header: Likewise. |
| 9726 | * runtime-po/en@boldquot.header: Likewise. |
| 9727 | * runtime-po/insert-header.sin: Likewise. |
| 9728 | * runtime-po/remove-potcdate.sin: Likewise. |
| 9729 | * runtime-po/Makevars: Likewise. |
| 9730 | * runtime-po/LINGUAS: Likewise. |
| 9731 | * runtime-po/de.po: Likewise; we will rely on the translation project |
| 9732 | to maintain this, so "bootstrap" should get it. |
| 9733 | * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine |
| 9734 | its value. |
| 9735 | * src/main.c (main): Bind the bison-runtime domain, too. |
| 9736 | |
| 9737 | 2005-07-12 Bruno Haible <bruno@clisp.org> |
| 9738 | |
| 9739 | * data/yacc.c: Include <libintl.h> when NLS is enabled. |

| 9741 | * po/POTFILES.in: Remove autogenerated file src/parse-gram.c. |
| 9742 | * runtime-po: New directory. |
| 9743 | * runtime-po/Makefile.in.in: New file, copied from po/, with modified |
| 9744 | $(DOMAIN).pot-update rule, so that old messages are never dropped. |
| 9745 | * runtime-po/Rules-quot: New file, copied from po/. |
| 9746 | * runtime-po/quot.sed: Likewise. |
| 9747 | * runtime-po/boldquot.sed: Likewise. |

| 9767 | (Internationalization): New section. |
| 9768 | |
| 9769 | 2005-07-12 Akim Demaille <akim@epita.fr> |
| 9770 | |
| 9771 | * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments, |
| 9772 | for consistency with the rest of the code. |
| 9773 | * src/symlist.h, src/symlist.c (symbol_list_print): Ditto. |
| 9774 | Add separators. |
| 9775 | |
| 9776 | 2005-07-12 Akim Demaille <akim@epita.fr> |
| 9777 | |
| 9778 | * src/parse-gram.y: Use %printer instead of YYPRINT. |
| 9779 | |
| 9780 | 2005-07-12 Akim Demaille <akim@epita.fr> |
| 9781 | |
| 9782 | * src/symtab.h, src/symtab.c (symbol_print): New. |
| 9783 | * src/symlist.h, src/symlist.c (symbol_list_print): New. |
| 9784 | * src/symlist.c (symbol_list_n_type_name_get): Report the culprit. |
| 9785 | |
| 9786 | 2005-07-12 Akim Demaille <akim@epita.fr> |
| 9787 | |
| 9788 | * data/glr.c (b4_syncline): Fix (swap) the definitions of |
| 9789 | b4_at_dollar and b4_dollar_dollar. |
| 9790 | |
| 9791 | 2005-07-11 Paul Eggert <eggert@cs.ucla.edu> |
| 9792 | |
| 9793 | * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer |
| 9794 | and Pennello's paper. |
| 9795 | |
| 9796 | 2005-07-09 Paul Eggert <eggert@cs.ucla.edu> |
| 9797 | |
| 9798 | * data/yacc.c (yyparse): Undo previous patch. Instead, |
| 9799 | set yylsp[0] and yyvsp[0] only if the initial action |
| 9800 | sets yylloc and yylval, respectively. |
| 9801 | |
| 9802 | * data/yacc.c (yyparse): In the initial action, set |
| 9803 | yylsp[0] and yyvsp[0] rather than yylloc and yylval. |
| 9804 | This avoids the use of undefined variables if the initial |
| 9805 | action does not set yylloc and/or yylval. |
| 9806 | |
| 9807 | 2005-07-07 Paul Eggert <eggert@cs.ucla.edu> |
| 9808 | |
| 9809 | * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh: |
| 9810 | * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc: |
| 9811 | Remove from CVS. These files are automatically generated. |
| 9812 | * examples/extexi: Clarify that this file is now part of Bison, |
| 9813 | not GNU M4, and that it works with any POSIX-compatible Awk. |
| 9814 | * examples/calc++/Makefile.am (run_extexi): Remove; not used. |
| 9815 | ($(calc_extracted)): Renamed from $(calc_sources_extracted), |
| 9816 | so that we also get calc++-parser.yy. Geneate it. |
| 9817 | Use $(AWK), not gawk, since any conforming Awk will do. |
| 9818 | Put comment before action, since older 'make' can't handle comment |
| 9819 | in action. |
| 9820 | $(BUILT_SOURCES): List all built sources, not just some of them. |
| 9821 | $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources. |
| 9822 | $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT. |
| 9823 | $($(calc_sources_generated)): Remove unnecessary test for existence |
| 9824 | of target. (This had a shell syntax error anyway; a stray "x".) |
| 9825 | (calc_extracted): List $(srcdir)/calc++-parser.yy, not |
| 9826 | calc++-parser.yy. |
| 9827 | * examples/.cvsignore, examples/calc++/.cvsignore: New files. |
| 9828 | |
| 9829 | * bootstrap (gnulib_modules): Add gettext, now that it's no longer |
| 9830 | implied by the other modules. |
| 9831 | |
| 9832 | 2005-07-06 Akim Demaille <akim@epita.fr> |
| 9833 | |
| 9834 | Bind examples/calc++ to the package. |
| 9835 | * examples/calc++/Makefile: Remove, replaced by... |
| 9836 | * examples/calc++/Makefile.am: ... this new file. |
| 9837 | * examples/calc++/test: Remove input. |
| 9838 | * examples/calc++/compile: Remove. |
| 9839 | * examples/Makefile.am: New. |
| 9840 | * configure.ac, Makefile.am: Adjust. |
| 9841 | * doc/Makefile.am (clean-local): New, for more recent texi2dvis. |
| 9842 | |
| 9843 | 2005-07-05 Paul Eggert <eggert@cs.ucla.edu> |
| 9844 | |
| 9845 | * data/glr.c (yyFail): Drastically simplify; since the format argument |
| 9846 | never had any % directives, we can simply pass it to yyerror. |
| 9847 | (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will |
| 9848 | be modified later, as that is the usual style in glr.c. |
| 9849 | Problems reported by Paul Hilfinger. |
| 9850 | |
| 9851 | Rewrite GLR parser to catch more buffer overrun, storage exhaustion, |
| 9852 | and size overflow errors. |
| 9853 | * data/glr.c: Include <stdio.h> etc. after user prolog, not before, |
| 9854 | in case the user prolog sets feature-test macros like _GNU_SOURCE. |
| 9855 | (YYSIZEMAX): New macro. |
| 9856 | (yystpcpy): New function, taken from yacc.c. |
| 9857 | (struct yyGLRStack.yyspaceLeft): Now size_t, not int. |
| 9858 | (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls, |
| 9859 | so that we don't have to maintain their signatures. |
| 9860 | (yyFail): Check for buffer overflow, by using vsnprintf rather |
| 9861 | than vsprintf. Allocate a bigger buffer if possible. |
| 9862 | Report an error if buffer allocation fails. |
| 9863 | (yyStackOverflow): New function. |
| 9864 | (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether |
| 9865 | the initialization was successful. It might fail if storage was |
| 9866 | exhausted. |
| 9867 | (yyexpandGLRStack): Add more checks for storage allocation failure. |
| 9868 | Use yyStackOverflow to report failures. |
| 9869 | (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction): |
| 9870 | (yysplitStack, yyprocessOneStack, yyparse, yypstack): |
| 9871 | Don't assume stack number fits in int. |
| 9872 | (yysplitStack): Check for storage allocation failure. |
| 9873 | (yysplitStack, yyprocessOneStack): Add pure_formals, so that we |
| 9874 | can print diagnostics on storage allocation failure. All callers |
| 9875 | changed. |
| 9876 | (yyresolveValue): Use yybool for boolean. |
| 9877 | (yyreportSyntaxError): Check for size-calculation overflow. |
| 9878 | This code is taken from yacc.c. |
| 9879 | (yyparse): Check for storage allocation errors when allocating |
| 9880 | the initial stack. |
| 9881 | |
| 9882 | 2005-07-05 Akim Demaille <akim@epita.fr> |
| 9883 | |
| 9884 | Extract calc++ from the documentation. |
| 9885 | * doc/bison.texinfo (Calc++): Add the extraction marks. |
| 9886 | * examples/extexi: New, from the aborted GNU Programming 2E. |
| 9887 | Separate the different paragraph of a file with empty lines. |
| 9888 | * examples/Makefile: Use it to extract the whole calc++ example. |
| 9889 | |
| 9890 | 2005-06-24 Akim Demaille <akim@epita.fr> |
| 9891 | |
| 9892 | * doc/bison.texinfo (C++ Parser Interface): Use defcv to define |
| 9893 | class typedefs. |
| 9894 | |
| 9895 | 2005-06-22 Akim Demaille <akim@epita.fr> |
| 9896 | |
| 9897 | * doc/bison.texinfo (C++ Language Interface): First stab. |
| 9898 | (C++ Parsers): Remove. |
| 9899 | |
| 9900 | 2005-06-22 Akim Demaille <akim@epita.fr> |
| 9901 | |
| 9902 | * data/lalr1.cc (yylex_): Honor %lex-param. |
| 9903 | |
| 9904 | 2005-06-22 Akim Demaille <akim@epita.fr> |
| 9905 | |
| 9906 | Start a set of simple examples. |
| 9907 | * examples/calc++/Makefile, examples/calc++/calc++-driver.cc, |
| 9908 | * examples/calc++/calc++-driver.hh, |
| 9909 | * examples/calc++/calc++-parser.yy, |
| 9910 | * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc, |
| 9911 | * examples/calc++/compile, examples/calc++/test: New. |
| 9912 | |
| 9913 | 2005-06-09 Paul Eggert <eggert@cs.ucla.edu> |
| 9914 | |
| 9915 | * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside |
| 9916 | extern "C" {}. This fixes a problem reported by Paul Hilfinger, |
| 9917 | which stems from the 2005-05-27 patch. |
| 9918 | |
| 9919 | 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU> |
| 9920 | |
| 9921 | * data/glr.c: Modify treatment of unused parameters to permit use |
| 9922 | of g++ (which doesn't allow __attribute__ ((unused)) for parameters). |
| 9923 | |
| 9924 | 2005-05-30 Paul Eggert <eggert@cs.ucla.edu> |
| 9925 | |
| 9926 | Fix infringement on user name space reported by Janos Zoltan Szabo. |
| 9927 | * data/yacc.c (yyparse): strlen -> yystrlen. |
| 9928 | |
| 9929 | 2005-05-30 Akim Demaille <akim@epita.fr> |
| 9930 | |
| 9931 | * data/lalr1.cc (_): New. |
| 9932 | Translate the various messages. |
| 9933 | |
| 9934 | 2005-05-27 Paul Eggert <eggert@cs.ucla.edu> |
| 9935 | |
| 9936 | Fix infringement on user name space reported by Bruno Haible. |
| 9937 | * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it. |
| 9938 | Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on |
| 9939 | the user's name space. |
| 9940 | (alloca): Include <stdlib.h> to get it, if it's not built in. |
| 9941 | (YYMALLOC, YYFREE): Define only if needed. |
| 9942 | (malloc, free): Declare, but only if needed, as this infringes on |
| 9943 | the user name space. |
| 9944 | |
| 9945 | 2005-05-25 Paul Eggert <eggert@cs.ucla.edu> |
| 9946 | |
| 9947 | Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible. |
| 9948 | * lib/bitset.c (bitset_print): Don't assume size_t can be printed |
| 9949 | with %d format. |
| 9950 | * lib/ebitset.c (min, max): Undef before defining. |
| 9951 | * lib/vbitset.c (min, max): Likewise. |
| 9952 | * lib/subpipe.c (create_subpipe): Save local variables in case |
| 9953 | vfork clobbers them. |
| 9954 | |
| 9955 | 2005-05-24 Bruno Haible <bruno@clisp.org> |
| 9956 | |
| 9957 | * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the |
| 9958 | error message syntax used by gcc-4.0. |
| 9959 | |
| 9960 | 2005-05-23 Paul Eggert <eggert@cs.ucla.edu> |
| 9961 | |
| 9962 | * README: Mention m4 1.4.3. Remove obsolete advice about |
| 9963 | Sun Forte Developer 6 update 2, VMS, and MS-DOS. |
| 9964 | |
| 9965 | * bootstrap: Remove workaround for problem I encountered with |
| 9966 | gettext 0.14.1; it seems to be fixed now. |
| 9967 | |
| 9968 | 2005-05-22 Paul Eggert <eggert@cs.ucla.edu> |
| 9969 | |
| 9970 | * NEWS: Version 2.0a. |
| 9971 | |
| 9972 | * src/files.c: Include "stdio-safer.h"; this fixes a typo in |
| 9973 | the previous change. |
| 9974 | |
| 9975 | Various maintainer cleanups. |
| 9976 | * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*, |
| 9977 | conftest*, for benefit of CVS commands run at the same time as |
| 9978 | "configure". Add build-aux, since "bootstrap" now creates it and |
| 9979 | its subfiles. |
| 9980 | * Makefile.cfg (move_if_change): Remove. |
| 9981 | * Makefile.maint: Remove the update stuff; we now use "bootstrap". |
| 9982 | (ftp-gnu, www-gnu, move_if_change, local_updates, update): |
| 9983 | (po_repo, do-po-update, po-update, wget_files, get-targets): |
| 9984 | (config.guess-url_prefix, config.sub-url_prefix): |
| 9985 | (ansi2knr.c-url_prefix, texinfo.tex-url_prefix): |
| 9986 | (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url): |
| 9987 | ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update): |
| 9988 | Remove. |
| 9989 | * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux; |
| 9990 | this is now the recommended name. |
| 9991 | * config/.cvsignore: Remove config.guess, config.rpath, config.sub, |
| 9992 | depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex, |
| 9993 | ylwrap. These files now go into build-aux. |
| 9994 | * config/move-if-change: Remove. |
| 9995 | * config/prev-version.txt: Bump from 1.75 to 2.0. |
| 9996 | |
| 9997 | * bootstrap: Add stdio-safer, unistd-safer modules. |
| 9998 | Remove m4/glibc2.m4 (introduced by latest gnulib, but |
| 9999 | we don't need it). |
| 10000 | * lib/.cvsignore: Add dup-safer.c, fd-safer.c, |
| 10001 | fopen-safer.c, stdio-safer.h, unistd-safer.h. |
| 10002 | * lib/subpipe.c: Include "unistd-safer.h". |
| 10003 | (create_subpipe): Make sure all the newly-created |
| 10004 | file descriptors are > 2, so that diagnostics don't |
| 10005 | get sent down them (which might cause Bison to hang, in theory). |
| 10006 | * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4. |
| 10007 | * src/files.c (xfopen): Use fopen_safer, not fopen. |
| 10008 | |
| 10009 | * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port |
| 10010 | yesterday's yacc.c fix. |
| 10011 | |
| 10012 | 2005-05-21 Paul Eggert <eggert@cs.ucla.edu> |
| 10013 | |
| 10014 | * data/glr.c, data/lalr1.cc: Update copyright date. |
| 10015 | |
| 10016 | Fix a destructor bug reported by Wolfgang Spraul in |
| 10017 | <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>. |
| 10018 | * data/yacc.c (yyabortlab): Don't call destructor, and |
| 10019 | don't set yychar to EMPTY. |
| 10020 | (yyoverflowlab): Don't call destructor. |
| 10021 | (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY. |
| 10022 | * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines, |
| 10023 | since we no longer output the message "discarding lookahead token |
| 10024 | end of input ()". |
| 10025 | |
| 10026 | 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU> |
| 10027 | |
| 10028 | * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to |
| 10029 | fix a small glitch in debugging output. |
| 10030 | (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline |
| 10031 | after YY_SYMBOL_PRINT where needed. |
| 10032 | |
| 10033 | (struct yyGLRState): Add some comments. |
| 10034 | (struct yySemanticOption): Add some comments. |
| 10035 | (union yyGLRStackItem): Add comment. |
| 10036 | |
| 10037 | (yymergeOptionSets): Correct this to properly perform the union, |
| 10038 | avoiding infinite reported by Michael Rosien. |
| 10039 | Update comment. |
| 10040 | |
| 10041 | * tests/glr-regression.at: Add test for GLR merging error reported |
| 10042 | by M. Rosien. |
| 10043 | |

| 10089 | * tests/actions.at: Test that stack overflow invokes destructors. |
| 10090 | From Marcus Holland-Moritz. |
| 10091 | * data/yacc.c (yyerrlab): Move the code that destroys the stack |
| 10092 | from here.... |
| 10093 | (yyreturn): to here. That way, destructors are called properly |
| 10094 | even if the stack overflows, or the user calls YYACCEPT or |
| 10095 | YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz. |
| 10096 | (yyoverflowlab): Destroy the lookahead. |
| 10097 | |
| 10098 | 2005-04-24 Paul Eggert <eggert@cs.ucla.edu> |
| 10099 | |

| 10107 | since users don't want to see C escapes. |
| 10108 | * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes |
| 10109 | in diagnostics. |

| 10114 | |
| 10115 | * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if |
| 10116 | the data size is known to be too small and we can't increase it. |
| 10117 | This works around an HP-UX 11.00 glitch reported by Andrew Benham. |

| 10120 | |
| 10121 | * src/parse-gram.y: Include quotearg.h. |
| 10122 | (string_as_id): Quote $1 before using it as a key, since the |
| 10123 | lexer no longer quotes it for us. |
| 10124 | (string_content): Don't strip quotes, since lexer no longer |
| 10125 | quotes it for us. |
| 10126 | * src/scan-gram.l: Include quotearg.h. |
| 10127 | ("\""): Omit quote. |
| 10128 | ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as |
| 10129 | a key, since the rest of the lexer doesn't quote it. |
| 10130 | * src/symtab.c (symbol_get): Don't quote symbol; caller does it now. |

| 10135 | (YYSIZE_T): Define to unsigned long int when using an older compiler. |
| 10136 | (yyparse): Revamp code to generate long syntax error message, to |
| 10137 | make it easier to translate, and to avoid problems with arithmetic |
| 10138 | overflow. Change "virtual memory" to "memory" in diagnostic, since |
| 10139 | we don't know whether the memory is virtual. |

| 10143 | * NEWS: Bison-generated C parsers now use the _ macro to |
| 10144 | translate strings. |
| 10145 | * data/yacc.c (_) [!defined _]: New macro. |
| 10146 | All English strings wrapped inside this macro. |
| 10147 | * doc/bison.texinfo (Bison Parser): Document _. |
| 10148 | * po/POTFILES.in: Include src/parse-gram.c, since it now |
| 10149 | includes translateable strings that parse-gram.y doesn't. |

| 10160 | |
| 10161 | * tests/regression.at (Token definitions): Don't use a token named |
| 10162 | c, as that generates a "#define c ..." that runs afoul of buggy |
| 10163 | stdlib.h that uses the identifier c as a member of struct |
| 10164 | drand48_data. Problem reported by Horst Wente. |

| 10189 | |
| 10190 | * src/vcg.h: Comment fix. |
| 10191 | * src/vcg_defaults.h: Parenthesize macro bodies to make them safe. |

| 10203 | |
| 10204 | * src/output.c (escaped_output): Renamed from |
| 10205 | escaped_file_name_output, since we now use it for symbol tags as |
| 10206 | well. All uses changed. |
| 10207 | (symbol_destructors_output, symbol_printers_output): |

| 10223 | |
| 10224 | * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in |
| 10225 | example, reported by Derek M Jones. Also, make the example even |
| 10226 | more outrageous, to better illustrate how bad the problem is. |

| 10240 | |
| 10241 | * tests/glr-regression.at (Improper handling of embedded actions |
| 10242 | and dollar(-N) in GLR parsers): Renamed from "Improper handling of |
| 10243 | embedded actions and $-N in GLR parsers", work around an Autoconf bug |
| 10244 | with dollar signs in test names. |
| 10245 | * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n", |

| 10273 | |
| 10274 | * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register" |
| 10275 | keyword; it's not needed with modern compilers, and it doesn't |

| 10317 | |
| 10318 | * src/scan-skel.l ("@output ".*\n): Don't close standard output. |
| 10319 | Problem reported by Hans Aberg. |
| 10320 | * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO. |

| 10329 | 2004-12-25 Paul Eggert <eggert@cs.ucla.edu> |
| 10330 | |
| 10331 | * NEWS: Version 2.0. Reformat the existing news items since |
| 10332 | 1.875, so that related items are grouped together. |
| 10333 | * configure.ac (AC_INIT): Bump version to 2.0. |
| 10334 | * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0. |
| 10335 | |
| 10336 | * tests/torture.at (Exploding the Stack Size with Alloca): Set |
| 10337 | YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined; |
| 10338 | otherwise, we're not testing alloca. Unfortunately there's no |
| 10339 | simple way to consult HAVE_ALLOCA here. |
| 10340 | |
| 10341 | * data/lalr1.cc (yydestruct_): Pacify unused variable warning |
| 10342 | for yymsg, too. |
| 10343 | |
| 10344 | * src/LR0.c (new_itemsets): Use memset rather than zeroing by |
| 10345 | hand. This avoids a warning about comparing int to size_t when |
| 10346 | GCC warnings are enabled. |
| 10347 | |
| 10348 | 2004-12-22 Paul Eggert <eggert@cs.ucla.edu> |
| 10349 | |
| 10350 | * NEWS: Bison-generated parsers no longer default to using the |
| 10351 | alloca function (when available) to extend the parser stack, due |
| 10352 | to widespread problems in unchecked stack-overflow detection. |
| 10353 | * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's |
| 10354 | responsibility to set it to a positive value. This lets the user |
| 10355 | specify a value that is not a preprocessor constant. |
| 10356 | * data/yacc.c (YYMAXDEPTH): Likewise. |
| 10357 | (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero. |
| 10358 | * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs |
| 10359 | to be a compile-time constant. However, explain the constraints on it. |
| 10360 | Also, explain the constraints on YYINITDEPTH. |
| 10361 | (Table of Symbols): Explain that alloca is no longer the default. |
| 10362 | Explain the user's responsibility if they define YYSTACK_USE_ALLOCA |
| 10363 | to 1. |
| 10364 | |

| 10372 | Private, not public. |
| 10373 | (parser::parse): Return ints, not bool. |
| 10374 | Returning a bool introduces a problem: 0 corresponds to false, and |
| 10375 | it seems weird to return false on success. Returning true changes |
| 10376 | the conventions for yyparse. |
| 10377 | Alternatively we could return void and send an exception. |
| 10378 | There is no clear consensus (yet?). |
| 10379 | (state_stack, semantic_stack, location_stack): Rename as... |

| 10393 | * data/lalr1.cc (b4_filename_type): New. |
| 10394 | (position::filename): Use it. |
| 10395 | (parser.hh): Move the inclusion of stack.hh and location.hh below |
| 10396 | the user code, so that needed headers for the filename type can be |
| 10397 | included first. |
| 10398 | Forward declare them before the user code. |
| 10399 | * tests/Makefile.am (check-local, installcheck-local): Pass |

| 10421 | 2004-12-17 Paul Eggert <eggert@cs.ucla.edu> |
| 10422 | |
| 10423 | Remove uses of 'short int' and 'unsigned short int'. This raises |
| 10424 | some arbitrary limits. It uses more memory but nowadays that's |
| 10425 | not much of an issue. |
| 10426 | |
| 10427 | This change does not affect the generated parsers; that's a different |
| 10428 | task, as some users will want to conserve memory there. |
| 10429 | |
| 10430 | Ideally we should use size_t to represent all object counts, and |
| 10431 | something like ptrdiff_t to represent signed differences of object |
| 10432 | counts; but that will require more code-cleanup than I have the |
| 10433 | time to do right now. |
| 10434 | |
| 10435 | * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions): |

| 10469 | |
| 10470 | * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location): |
| 10471 | Parenthesize rhs to avoid obscure problems with mistakes like |
| 10472 | "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all. |
| 10473 | * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location, |
| 10474 | b4_rhs_location): Likewise. |

| 10481 | yacc.c: be sure to stay within yycheck_. |
| 10482 | * tests/actions.at: Re-enable C++ tests. |
| 10483 | |
| 10484 | 2004-12-16 Akim Demaille <akim@epita.fr> |
| 10485 | |
| 10486 | * src/print_graph.c (print_graph): Remove layoutalgorithm uses for |
| 10487 | real. |
| 10488 | |
| 10489 | 2004-12-16 Akim Demaille <akim@epita.fr> |
| 10490 | |
| 10491 | Use #define to handle the %name-prefix. |
| 10492 | |
| 10493 | * data/glr.c, data/yacc.c: Comment changes. |
| 10494 | * data/lalr1.cc (yylex): Use #define to select the name of yylex, |
| 10495 | so that one can refer to yylex in the parser file, and have it |
| 10496 | renamed, as is the case with other skeletons. |
| 10497 | |
| 10498 | 2004-12-16 Akim Demaille <akim@epita.fr> |

| 10520 | 2004-12-15 Paul Eggert <eggert@cs.ucla.edu> |
| 10521 | |
| 10522 | Fix some problems reported by twlevo at xs4all. |
| 10523 | * src/symtab.c (symbol_new): Report an error if the input grammar |
| 10524 | contains too many symbols. This is better than calling abort() later. |
| 10525 | * src/vcg.h (enum layoutalgorithm): Remove. All uses removed. |
| 10526 | (struct node, struct graph): |
| 10527 | Rename member expand to stretch. All uses changed. |

| 10540 | (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_) |
| 10541 | (yypop_, yyreport_syntax_error_, yytranslate_): this. |

| 10544 | |
| 10545 | * data/lalr1.cc (lex_): Rename as... |
| 10546 | (yylex_): this. |
| 10547 | Move the trace here. |
| 10548 | Take the %name-prefix into account. |
| 10549 | Reported by Alexandre Duret-Lutz. |
| 10550 | |
| 10551 | 2004-12-15 Akim Demaille <akim@epita.fr> |
| 10552 | |
| 10553 | Simplify the C++ parser constructor. |
| 10554 | |
| 10555 | * data/lalr1.cc (debug_): Rename as... |
| 10556 | (yydebug_): so that the parser's internals are always in the yy* |
| 10557 | pseudo namespace. |
| 10558 | Adjust uses. |
| 10559 | (b4_parse_param_decl): Remove the leading comma as it is now only |
| 10560 | called as unique argument list. |
| 10561 | (Parser::Parser): Remove the constructor accepting a location and |
| 10562 | an initial debugging level. |
| 10563 | Remove from the other ctor the argument for the debugging level. |
| 10564 | (debug_level_type, debug_level, set_debug_level): New. |
| 10565 | |
| 10566 | * tests/actions.at, tests/calc.at, tests/regression.at: Adjust |
| 10567 | constructor calls. |
| 10568 | |
| 10569 | 2004-12-15 Akim Demaille <akim@epita.fr> |
| 10570 | |
| 10571 | Remove b4_root related material: failure experiment |
| 10572 | (which goal was to allow to derive from a class). |
| 10573 | |
| 10574 | * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove |
| 10575 | definitions and uses. |
| 10576 | |
| 10577 | 2004-12-14 Paul Eggert <eggert@cs.ucla.edu> |
| 10578 | |
| 10579 | * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items, |
| 10580 | not 2, since it's not portable to subtract 1 from the start of an |
| 10581 | array. The new item 0 is never set or used. All uses changed. |
| 10582 | |
| 10583 | (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming |
| 10584 | the default definition of YYLLOC_DEFAULT. Problem reported |
| 10585 | by Frank Heckenbach. |
| 10586 | |
| 10587 | 2004-12-12 Paul Eggert <eggert@cs.ucla.edu> |
| 10588 | |
| 10589 | * data/glr.c (YYRHSLOC): Don't have two definitions, one for |
| 10590 | the normal case and one for the error case. Just use the |
| 10591 | first one uniformly. Problem reported by Frank Heckenbach. |
| 10592 | (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can |
| 10593 | use exactly the same macro in both places. |
| 10594 | (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE, |
| 10595 | so that the normal-case YYRHSLOC works for the error case too. |
| 10596 | All uses changed. |
| 10597 | * data/yacc.c (YYRHSLOC): New macro, taken from glr.c. |
| 10598 | (YYLLOC_DEFAULT): Use the same macro as glr.c. |
| 10599 | * doc/bison.texinfo (Location Default Action): Don't claim that |
| 10600 | we have an array of locations. Use the same macro for both glr |
| 10601 | and lalr parsers. Mention YYRHSLOC. Mention what happens when |
| 10602 | the index is 0. |
| 10603 | |
| 10604 | 2004-12-10 Paul Eggert <eggert@cs.ucla.edu> |

| 10612 | * NEWS: Version 1.875e. |
| 10613 | * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e. |
| 10614 | |
| 10615 | * src/scan-skel.l: Include "complain.h", for "fatal". |
| 10616 | |
| 10617 | * src/relation.h (relation_print, relation_digraph): |
| 10618 | Relation sizes are of type relation_node, not size_t (this is |
| 10619 | merely a doc fix, since the two types are equivalent). |
| 10620 | (relation_transpose): Relation sizes are of type relation_node, |
| 10621 | not int. |
| 10622 | * src/relation.c: Likewise. |
| 10623 | (top, infinity): Now of type relation_node, not int. |
| 10624 | (traverse, relation_transpose): Use relation_node, not int. |
| 10625 | |
| 10626 | * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args |
| 10627 | with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning. |
| 10628 | (yyparse): Remove unused local introduced in 2004-10-25 patch. |
| 10629 | |
| 10630 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg |
| 10631 | specifying whether the test should be skipped. Use it tp |
| 10632 | specify that the [%defines %skeleton "lalr1.cc"] tests currently |
| 10633 | fail on some hosts, and should be skipped. |
| 10634 | |
| 10635 | 2004-12-08 Paul Eggert <eggert@cs.ucla.edu> |
| 10636 | |
| 10637 | * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers |
| 10638 | changed to use xcalloc, xnmalloc, xnrealloc, respectively, |
| 10639 | unless otherwise specified below. |
| 10640 | |
| 10641 | * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc, |
| 10642 | to allocate kernel_base, kernel_items, kernel_size, since |
| 10643 | they needn't be initialized to 0. |
| 10644 | (allocate_storgae): Likewise, for shiftset, redset, shift_symbol. |
| 10645 | * src/closure.c (new_closure): Likewise, for itemset. |
| 10646 | * src/derives.c (derives_compute): Likewise, for delts, derives, q. |

| 10662 | (pack_table): Likewise for base, pos, check. |
| 10663 | (tables_generate): Likewise for width. |
| 10664 | |
| 10665 | * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base |
| 10666 | for initial core. Just have a separate core, so we needn't worry |
| 10667 | about whether kernel_size and kernel_base are initialized. |
| 10668 | |
| 10669 | * src/LR0.c (shift_symbol, redset, shiftset, kernel_base, |
| 10670 | kernel_size, kernel_items): Remove unnecessary initialization. |

| 10676 | conflrow, conflict_table, conflict_list, table, check): |
| 10677 | Likewise. |
| 10678 | |
| 10679 | * src/closure.c (new_closure): Arg is of type unsigned int, not int. |
| 10680 | This is because all callers pass unsigned int. |
| 10681 | * src/closure.h (new_closure): Likewise. |
| 10682 | |
| 10683 | * src/lalr.c (initialize_F): Initialize reads[i] in all cases. |
| 10684 | (build_relations): Initialize includes[i] in all cases. |
| 10685 | * src/reader.c (packgram): Always initialize rules[ruleno].prec |
| 10686 | and rules[ruleno].precsym. Initialize members in order. |
| 10687 | * src/relation.c (relation_transpose): Always initialize new_R[i] |
| 10688 | and end_R[i]. |
| 10689 | * src/table.c (conflict_row): Initialize 0 at end of conflict_list. |
| 10690 | |
| 10691 | * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0]; |
| 10692 | conflict_list[0] was always 0, but now it isn't initialized. |
| 10693 | |
| 10694 | * src/table.c (table_grow): When conflict_table grew, the grown |
| 10695 | area wasn't cleared. Fix this. |
| 10696 | |
| 10697 | * lib/.cvsignore: Add strdup.c, strdup.h. |
| 10698 | * m4/.cvsignore: Add strdup.m4. |

| 10701 | |
| 10702 | * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro. |
| 10703 | * src/lalr.c (set_goto_map): Don't allow ngotos to equal |
| 10704 | GOTO_NUMBER_MAXIMUM, since we occasionally compute |
| 10705 | ngotos + 1 without checking for overflow. |
| 10706 | (build_relations): Use END_NODE, not -1, to denote end of edges. |
| 10707 | * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge, |
| 10708 | build_relations): Use goto_number, not int, for goto numbers. |

| 10711 | 2004-11-23 Akim Demaille <akim@epita.fr> |
| 10712 | |
| 10713 | * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead |
| 10714 | of #defining from yystype. |
| 10715 | Don't typedef yystype, C++ does not need it. |
| 10716 | This lets it possible to forward declare it as union. |
| 10717 | |
| 10718 | 2004-11-23 Paul Eggert <eggert@cs.ucla.edu> |
| 10719 | |

| 10741 | Use it instead of cdebug_. |
| 10742 | (Parser::debug_stream, Parser::set_debug_stream): New. |
| 10743 | (Parser::symprint_): Define cdebug_ for temporary backward |
| 10744 | compatibility. |
| 10745 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use |
| 10746 | debug_stream (). |

| 10749 | |
| 10750 | * data/lalr1.cc (Parser:print_): Remove, use %printer instead. |

| 10758 | Problem reported by Frank Heckenbach. |
| 10759 | |
| 10760 | 2004-10-25 Akim Demaille <akim@epita.fr> |
| 10761 | |
| 10762 | * data/glr.c (YYRHSLOC): Move its definition next to its uses. |
| 10763 | Introduce another definition to address simple location arrays. |
| 10764 | (yyGLRStack): New member: yyerror_range. |
| 10765 | (yyrecoverSyntaxError, yyparse): Update it. |
| 10766 | (yyrecoverSyntaxError): Use it when shifting the error token to |
| 10767 | have an accurate range, equivalent to the one computed by both |
| 10768 | yacc.c and lalr1.cc. |
| 10769 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so |
| 10770 | that column numbers start at column 0, as per GNU Coding |
| 10771 | Standards, the others tests, and the doc. |
| 10772 | (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC): |
| 10773 | Adjust to the above change (first column is 0). |
| 10774 | And adjust the location of the "<error>", now covering the whole |
| 10775 | line. |
| 10776 | |
| 10777 | 2004-10-22 Akim Demaille <akim@epita.fr> |

| 10781 | * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit |
| 10782 | initial values, since they're never used. |
| 10783 | (set_goto_map): ngotos is now unsigned, so test for overflow |
| 10784 | by seeing whether it wraps around to zero. |
| 10785 | * src/lalr.h (goto_number): Now size_t, not short int. |
| 10786 | (GOTO_NUMBER_MAXIMUM): Remove. |
| 10787 | * src/relation.c (relation_print, traverse, relation_transpose): |
| 10788 | Check for END_NODE rather than looking at sign. |
| 10789 | * src/relation.h (END_NODE): New macro. |
| 10790 | (relation_node): Now size_t, not short int. |
| 10791 | |

| 10799 | |
| 10800 | * src/symtab.c (symbol_check_alias_consistency): Also check |
| 10801 | type names, destructors, and printers. |
| 10802 | Reported by Alexandre Duret-Lutz. |
| 10803 | Recode the handling of associativity and precedence in terms |
| 10804 | of symbol_precedence_set. |
| 10805 | Accept no redeclaration at all, not even equal to the previous |
| 10806 | value. |
| 10807 | (redeclaration): New. |
| 10808 | Use it to factor redeclaration complaints. |
| 10809 | (symbol_make_alias): Don't set the type of the alias, let |
| 10810 | symbol_check_alias_consistency do it as for other features. |
| 10811 | * src/symtab.h (symbol): Add new member prec_location, and |
| 10812 | type_location. |
| 10813 | * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them. |
| 10814 | * tests/input.at (Incompatible Aliases): New. |

| 10816 | 2004-10-09 Paul Eggert <eggert@cs.ucla.edu> |
| 10817 | |
| 10818 | .cvsignore fixes to accommodate gnulib changes, |
| 10819 | and the practice of naming build directories "_build". |
| 10820 | * .cvsignore: Add "_*". Sort. |
| 10821 | * lib/.cvsignore: Add getopt_.h, xalloc-die.c. |
| 10822 | * m4/.cvsignore: Add "*_gl.m4". |
| 10823 | |
| 10824 | 2004-10-06 Akim Demaille <akim@epita.fr> |
| 10825 | |
| 10826 | * src/parse-gram.y (add_param): Fix the truncation of trailing |
| 10827 | spaces. |
| 10828 | |
| 10829 | 2004-10-05 Akim Demaille <akim@epita.fr> |
| 10830 | |
| 10831 | In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless |
| 10832 | whether the reducion was empty or not. This leaves room to |
| 10833 | improve the use of YYLLOC_DEFAULT in such a case. |
| 10834 | lalr1.cc is still experimental, so changing this is acceptable. |
| 10835 | And finally, there are probably not many users who changed the |
| 10836 | handling of locations in GLR, so changing is admissible too. |
| 10837 | |
| 10838 | * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an |
| 10839 | empty reduction, set @$ to an empty location ending the previously |
| 10840 | stacked symbol. |
| 10841 | Adjust uses to make sure the code is triggered on empty |
| 10842 | reductions. |
| 10843 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the |
| 10844 | expected output: empty reductions have empty locations. |
| 10845 | |
| 10846 | 2004-09-29 Akim Demaille <akim@epita.fr> |
| 10847 | |
| 10848 | * data/lalr1.cc: Move towards a more standard C++ coding style |
| 10849 | for templates: Class < T > -> Class<T>. |
| 10850 | |
| 10851 | 2004-09-29 Akim Demaille <akim@epita.fr> |
| 10852 | |
| 10853 | * data/lalr1.cc: Reinstall the former ctor, for sake of |
| 10854 | compatibility, but warn it will be removed. |
| 10855 | Move towards a more standard C++ coding style (i.e., type *var -> |
| 10856 | type* var). |
| 10857 | |
| 10858 | 2004-09-27 Paul Eggert <eggert@cs.ucla.edu> |
| 10859 | |
| 10860 | * src/parse-gram.y (add_param): Rewrite to avoid strchr, |
| 10861 | since it's less likely to work if NULs are involved in the future. |
| 10862 | |
| 10863 | 2004-09-27 Akim Demaille <akim@epita.fr> |
| 10864 | |
| 10865 | * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration. |
| 10866 | |
| 10867 | 2004-09-27 Akim Demaille <akim@epita.fr> |
| 10868 | |
| 10869 | * data/lalr1.cc (b4_parse_param_decl_1): New. |
| 10870 | (b4_parse_param_decl): Use it to have different names between attribute |
| 10871 | and argument names. |
| 10872 | (b4_cc_constructor_call): Likewise. |
| 10873 | |
| 10874 | 2004-09-24 Akim Demaille <akim@epita.fr> |
| 10875 | |
| 10876 | * src/parse-gram.y (add_param): Strip the leading and trailing |
| 10877 | blanks from a formal argument declaration. |
| 10878 | (YY_LOCATION_PRINT): New. |
| 10879 | |
| 10880 | 2004-09-24 Akim Demaille <akim@epita.fr> |
| 10881 | |
| 10882 | * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation |
| 10883 | after the location. |
| 10884 | |
| 10885 | 2004-09-24 Akim Demaille <akim@epita.fr> |
| 10886 | |
| 10887 | * doc/bison.texinfo (Table of Symbols): Sort. |
| 10888 | |
| 10889 | 2004-09-21 Akim Demaille <akim@epita.fr> |
| 10890 | |
| 10891 | * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove |
| 10892 | the useless parentheses. |
| 10893 | Suggested by Paul Eggert. |
| 10894 | |
| 10895 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 10896 | |
| 10897 | Let the initial-action act on the look-ahead, and use it for the |
| 10898 | "initial push" (corresponding to an hypothetical beginning-of-file). |
| 10899 | And let lalr1.cc honor %initial-action. |
| 10900 | |
| 10901 | * doc/bison.texinfo (Initial Action Decl): Clarify, and add an |
| 10902 | example. |
| 10903 | * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment. |
| 10904 | (Parser::Parser): Remove the ctor that used to initialize it. |
| 10905 | (Parser::parse): Like in the other skeletons, issue the "starting |
| 10906 | parse" message before any action. |
| 10907 | Honor %initial-action. |
| 10908 | Initialize the stacks with the lookahead. |
| 10909 | * data/yacc.c: Let $$ and @$ in %initial-action designate the |
| 10910 | look-ahead. |
| 10911 | Push them in the stacks. |
| 10912 | * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations. |
| 10913 | |
| 10914 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 10915 | |
| 10916 | * doc/bison.texinfo (Initial Action Decl): New. |
| 10917 | |
| 10918 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 10919 | |
| 10920 | * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a |
| 10921 | clearer criterion to define it. |
| 10922 | (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL. |
| 10923 | When reducing on an empty RHS, use the latest stacked location as |
| 10924 | location. |
| 10925 | yylloc is not always available. |
| 10926 | * data/glr.c: Likewise. |
| 10927 | Also, honor initial-actions. |
| 10928 | |
| 10929 | 2004-09-20 Akim Demaille <akim@epita.fr> |
| 10930 | |
| 10931 | * data/yacc.c (YY_LOCATION_PRINT): New. |
| 10932 | Define when we know YYLTYPE's structure, i.e., when the default |
| 10933 | YYLLOC_DEFAULT is used. |
| 10934 | * data/c.m4 (b4_yysymprint_generate): Use it. |
| 10935 | * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial |
| 10936 | value of the result. |
| 10937 | (error_start_): Replace with... |
| 10938 | (error_range_): this location array. |
| 10939 | This allows to replace code relying on the implementation of |
| 10940 | locations by portable code. |
| 10941 | * data/yacc.c (yylerrsp): Replace with... |
| 10942 | (yyerror_range): this. |
| 10943 | Every time a token is popped, update yyerror_range[0], to have an |
| 10944 | accurate location for the error token. |
| 10945 | * data/glr.c (YY_LOCATION_PRINT): New. |
| 10946 | (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT: |
| 10947 | deference a pointer. |
| 10948 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer |
| 10949 | report the location in %printers. |
| 10950 | |
| 10951 | * src/scan-skel.l: Instead of abort, report error messages to ease |
| 10952 | understanding skeleton scanning failures. |
| 10953 | |
| 10954 | 2004-09-16 Akim Demaille <akim@epita.fr> |
| 10955 | |
| 10956 | * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as... |
| 10957 | (iterator, const_iterator): these, to be more in the C++ spirit. |
| 10958 | Also, return reverse iterators so that when displaying the stack |
| 10959 | we display its bottom first. |
| 10960 | (Parser::stack_print_, Parser::reduce_print_): Match the messages |
| 10961 | from yacc.c. |
| 10962 | We should probably use vector here though. |
| 10963 | |
| 10964 | 2004-09-16 Akim Demaille <akim@epita.fr> |
| 10965 | |
| 10966 | Have more complete shift traces. |
| 10967 | |
| 10968 | * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT |
| 10969 | to report Shifts instead of ad hoc YYDPRINTF invocations, |
| 10970 | including for the error token. |
| 10971 | * data/lalr1.cc (symprint_): Output the location. |
| 10972 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't |
| 10973 | output the location within the %printer. |
| 10974 | Activate GLR tests, at least to make sure they compile properly. |
| 10975 | They still don't pass though. |
| 10976 | * tests/calc.at: Adjust expect verbose output, since now "Entering |
| 10977 | state..." is on a different line than the "Shifting" message. |
| 10978 | |
| 10979 | 2004-09-08 Akim Demaille <akim@epita.fr> |
| 10980 | |
| 10981 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the |
| 10982 | Bison directive from the Bison file to the invocation of this |
| 10983 | macro, so that these directives are passed to |
| 10984 | AT_BISON_OPTION_PUSHDEFS to get correct help macros. |
| 10985 | Use these helping macros (e.g., AT_LOC, AT_VAL and so forth). |
| 10986 | Move the AT_SETUP/AT_CLEANUP outside, to report as test title |
| 10987 | the extra Bison directives instead of the whole series. |
| 10988 | Change the grammar so that there are recoverable errors, and |
| 10989 | unrecoverable errors. Now we can have the parser give up before |
| 10990 | consuming the whole input. As a result we now can observe that |
| 10991 | the lookahead is freed when needed. |
| 10992 | Change the parser source to parse argv[1] instead of a hard coded |
| 10993 | string. |
| 10994 | Simplify yylex, and give a value and location to EOF. |
| 10995 | Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that |
| 10996 | passed directives already coded in the file. |
| 10997 | Add some tests to check the location of "error". |
| 10998 | For some tests, the C++ parser is correct, and not yacc.c. |
| 10999 | For other tests, they provide different, but unsatisfying, values, |
| 11000 | so keep the C++ value so that at least one parser is "correct" |
| 11001 | according to the test suite. |
| 11002 | (Actions after errors): Remove, this is subsumed by the |
| 11003 | AT_CHECK_PRINTER_AND_DESTRUCTOR series. |
| 11004 | |
| 11005 | 2004-09-06 Akim Demaille <akim@epita.fr> |
| 11006 | |
| 11007 | * data/lalr1.cc: Adjust the indentation of the labels. |
| 11008 | (Parser::pop): New. |
| 11009 | Use it. |
| 11010 | |
| 11011 | 2004-09-06 Akim Demaille <akim@epita.fr> |
| 11012 | |
| 11013 | * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional |
| 11014 | argument, an informative message. |
| 11015 | Call YY_SYMBOL_PRINT. |
| 11016 | Adjust all callers: integrate the associated YY_SYMBOL_PRINT. |
| 11017 | * data/lalr1.cc (destruct_): Likewise. |
| 11018 | In addition, no longer depend on b4_yysymprint_generate and |
| 11019 | b4_yydestruct_generate to generate these functions, do it "by |
| 11020 | hand". |
| 11021 | |
| 11022 | 2004-09-03 Akim Demaille <akim@epita.fr> |
| 11023 | |
| 11024 | * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was |
| 11025 | invoked, yydestruct the lookahead. |
| 11026 | * tests/calc.at (Calculator $1): Update the expected lengths of |
| 11027 | traces: there is an added line for the discarded lookahead. |
| 11028 | * doc/bison.texinfo (Destructor Decl): Some rewording. |
| 11029 | Define "discarded" symbols. |
| 11030 | |
| 11031 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 11032 | |
| 11033 | * data/lalr1.cc (translate_, destruct_): No reason to be static. |
| 11034 | |
| 11035 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 11036 | |
| 11037 | * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used. |
| 11038 | (YYDSYMPRINTF): Rename as... |
| 11039 | (YY_SYMBOL_PRINT): this. |
| 11040 | * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous |
| 11041 | two. |
| 11042 | Use it instead of direct symprint_ calls. |
| 11043 | (yybackup): Tweak the "Now at end of input" case to match yacc.c's |
| 11044 | one. |
| 11045 | |
| 11046 | 2004-09-02 Akim Demaille <akim@epita.fr> |
| 11047 | |
| 11048 | * data/lalr1.cc (b4_yysymprint_generate): New. |
| 11049 | (symprint_): New member function, defined when YYDEBUG. |
| 11050 | Use it consistently instead of token/nterm debugging output by |
| 11051 | hand. |
| 11052 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust |
| 11053 | %printer calls to use cdebug_ when using lalr1.cc. |
| 11054 | |
| 11055 | 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 11056 | |
| 11057 | * data/glr.c: Guard the declarations of yypstack and yypdumpstack |
| 11058 | with #ifdef YYDEBUG. |
| 11059 | |
| 11060 | 2004-08-26 Akim Demaille <akim@epita.fr> |
| 11061 | |
| 11062 | * doc/bison.texinfo (Implementing Loops): Rename as... |
| 11063 | (Implementing Gotos/Loops): this. |
| 11064 | |
| 11065 | 2004-08-13 Paul Eggert <eggert@cs.ucla.edu> |
| 11066 | |
| 11067 | Adjust to latest gnulib. |
| 11068 | * bootstrap (gnulib_modules): Add xalloc-die. |
| 11069 | Set LC_ALL=C so that file names sort consistently. |
| 11070 | Prefer the gnulib copies of gettext.m4, glibc21.m4, |
| 11071 | inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4, |
| 11072 | uintmax_t.m4, ulonglong.m4. |
| 11073 | (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4, |
| 11074 | po.m4 since we are now using _gl.m4 instead. |
| 11075 | |
| 11076 | 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 11077 | |
| 11078 | * src/scan-action.l: Remove. Scanning of semantic actions is |
| 11079 | handled in scan-gram.l. |
| 11080 | |
| 11081 | 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com> |
| 11082 | |
| 11083 | * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup. |
| 11084 | |
| 11085 | * src/location.h (struct): The file member is a uniqstr. |
| 11086 | (equal_boundaries): Use UNIQSTR_EQ for comparison. |
| 11087 | |
| 11088 | 2004-07-22 Paul Eggert <eggert@cs.ucla.edu> |
| 11089 | |
| 11090 | Fix bug with non-%union parsers that have printers or destructors, |
| 11091 | which led to a Bison core dump. Reported by Peter Fales in |
| 11092 | <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>. |
| 11093 | |
| 11094 | * data/c.m4 (b4_symbol_actions): Don't assume %union was used. |
| 11095 | * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE, |
| 11096 | not to our own type. |
| 11097 | * src/output.c (symbol_destructors_output, symbol_printers_output): |
| 11098 | Don't assume %union. |
| 11099 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR, |
| 11100 | AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument |
| 11101 | UNION-FLAG. All callers changed. |
| 11102 | (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union. |
| 11103 | Use type char, not unsigned int, when declaring an array of char; |
| 11104 | this lets us remove a cast. |
| 11105 | (Printers and Destructors): Add non-%union test cases. |
| 11106 | |
| 11107 | 2004-06-21 Paul Eggert <eggert@cs.ucla.edu> |
| 11108 | |
| 11109 | * doc/bison.texinfo: Minor editorial changes, mostly to the new |
| 11110 | GLR writeups. E.g., avoid frenchspacing and the future tense, |
| 11111 | change "lookahead" to "look-ahead", and change "wrt" to "with |
| 11112 | respect to". |
| 11113 | |
| 11114 | 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU> |
| 11115 | |
| 11116 | * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements): |
| 11117 | New sections, split off from the GLR Parsers section. Put the new |
| 11118 | Simple GLR Parser near the start of the GLR section, for clarity. |
| 11119 | Rewrite connective text. |
| 11120 | |
| 11121 | 2004-06-21 Frank Heckenbach <frank@g-n-u.de> |
| 11122 | |
| 11123 | * doc/bison.texinfo (Simple GLR Parsers): New section. |

| 11125 | 2004-06-21 Paul Eggert <eggert@cs.ucla.edu> |
| 11126 | |
| 11127 | * NEWS, TODO, doc/bison.texinfo: |
| 11128 | Use "look-ahead" instead of "lookahead", to be consistent. |
| 11129 | * REFERENCES: Fix incorrect reference to DeRemer and Pennello, |
| 11130 | while we're fixing "look-ahead". |
| 11131 | * src/conflicts.c (shift_set): Renamed from shiftset. |

| 11155 | |
| 11156 | Don't assume the C++ compiler takes the same arguments as the C compiler |
| 11157 | (trivial change). |

| 11167 | * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr. |
| 11168 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): |
| 11169 | Output to a .cc file for C++, not to a .c file. |
| 11170 | * tests/calc.at (AT_CHECK_CALC): Likewise. |
| 11171 | * tests/regression.at (AT_CHECK_DANCER): Likewise. |
| 11172 | * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c. |

| 11180 | |
| 11181 | Spent a few hours checking out which prerequisite versions the |
| 11182 | current sources actually require. I went all the way back to |
| 11183 | Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated |
| 11184 | a seemingly endless set of combinations of versions more recent |
| 11185 | than that. The bottom line is that the current sources require |
| 11186 | fairly recent versions of the build tools, and it'll be some work |
| 11187 | to change this. |
| 11188 | * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59. |
| 11189 | (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8. |
| 11190 | (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12. |
| 11191 | Add comments explaining why those particular versions are |
| 11192 | currently needed. |
| 11193 | |
| 11194 | * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug |
| 11195 | in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in |
| 11196 | <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>. |
| 11197 | |
| 11198 | * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work |
| 11199 | (it fails with a Autoconf-without-aclocal-m4 diagnostic). |
| 11200 | |
| 11201 | 2004-05-26 Paul Eggert <eggert@cs.ucla.edu> |
| 11202 | |
| 11203 | * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to |
| 11204 | 0.11.5. Suggested by Bruno Haible. |
| 11205 | * bootstrap: Remove gettext version checking. |
| 11206 | |
| 11207 | * doc/bison.texinfo (Decl Summary): Also mention that %union |
| 11208 | can depend on prerequisite types. Problem reported by Tim |
| 11209 | Van Holder. |
| 11210 | |
| 11211 | 2004-05-25 Paul Eggert <eggert@cs.ucla.edu> |
| 11212 | |
| 11213 | * README: Mention GNU m4 1.4 bugs and Akim's patched version. |
| 11214 | * README-alpha: Don't tell people not to package this. |
| 11215 | |
| 11216 | * bootstrap: Don't assume $(...) works; use `...` instead. |
| 11217 | Problem reported by Paul Hilfinger. Also, diagnose non-GNU |
| 11218 | gettext better. |
| 11219 | |
| 11220 | * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's |
| 11221 | put into the -d output file, and mention what to do if YYSTYPE is |
| 11222 | defined as a macro. |
| 11223 | |
| 11224 | 2004-05-24 Paul Eggert <eggert@cs.ucla.edu> |
| 11225 | |
| 11226 | Undo change made earlier today: it caused autopoint to not bring |
| 11227 | in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for |
| 11228 | autopoint's. |
| 11229 | |
| 11230 | * bootstrap: Check that gettext version matches what's in |
| 11231 | configure.ac. Warn users to ignore robots.txt ERROR 404. |
| 11232 | * bootstrap: Undo today's earlier change (logged below). |
| 11233 | * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise. |
| 11234 | |
| 11235 | The gettext version checking is causing more trouble than it's |
| 11236 | curing; remove it. Problem reported by Paul Hilfinger. |
| 11237 | |
| 11238 | * bootstrap: Issue a warning that one can expect a message |
| 11239 | 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'. |
| 11240 | * configure.ac (AM_GNU_GETTEXT_VERSION): Remove. |
| 11241 | |
| 11242 | 2004-05-23 Paul Eggert <eggert@cs.ucla.edu> |
| 11243 | |
| 11244 | Ensure that the C++ compiler used for testing actually works on a |
| 11245 | simple test program; if not, skip the C++-related tests. Problem |
| 11246 | reported by Vin Shelton in: |
| 11247 | http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html |
| 11248 | |
| 11249 | * m4/cxx.m4: New file. |
| 11250 | * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add. |
| 11251 | * tests/atlocal.in (BISON_CXX_WORKS): Add. |
| 11252 | * tests/local.at (AT_COMPILE_CXX): Use it. |
| 11253 | |
| 11254 | 2004-05-21 Paul Eggert <eggert@cs.ucla.edu> |
| 11255 | |
| 11256 | * data/glr.c (yylloc): Output this macro even if locations are not |
| 11257 | being generated, as the GLR parser needs it even in that case. |
| 11258 | Problem reported by Troy A. Johnson |
| 11259 | <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>. |
| 11260 | |
| 11261 | * configure.ac (AC_INIT): Update to 1.875e. |
| 11262 | |
| 11263 | 2004-05-21 Paul Eggert <eggert@cs.ucla.edu> |
| 11264 | |
| 11265 | * NEWS: Version 1.875d. |
| 11266 | * configure.ac (AC_INIT): Likewise. |
| 11267 | * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d. |
| 11268 | |
| 11269 | * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow, |
| 11270 | -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current |
| 11271 | lalr1.cc runs afoul of the first, and the last two are no longer |
| 11272 | supported by GCC 3.4.0. |
| 11273 | * README: Mention GNU m4 1.4 or later; mention m4 patches. |
| 11274 | * HACKING: Use ./bootstrap, not "make update" to import foreign files. |
| 11275 | |
| 11276 | 2004-05-06 Paul Eggert <eggert@cs.ucla.edu> |
| 11277 | |
| 11278 | * src/muscle_tab.c (hash_muscle): Accept and return size_t, not |

| 11284 | 2004-05-03 Paul Eggert <eggert@cs.ucla.edu> |
| 11285 | |
| 11286 | * NEWS: Unescaped newlines are no longer allowed in char & strings. |
| 11287 | |
| 11288 | * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER, |
| 11289 | SC_CHARACTER,SC_STRING>): Reject unescaped newlines in |
| 11290 | character and string literals. |
| 11291 | (unexpected_end): New function. |
| 11292 | (unexpected_eof): Use it. |
| 11293 | (unexpected_newline): New function. |
| 11294 | (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate |
| 11295 | actions. |
| 11296 | |
| 11297 | * NEWS: Document %expect-rr. |
| 11298 | |
| 11299 | * bootstrap (--gnulib-srcdir=*, --cvs-user=*): |
| 11300 | Fix typo by replacing $1 with $option. |
| 11301 | Remove more 'intl'-related files. |
| 11302 | Don't DEFUN AM_INTL_SUBDIR twice. |
| 11303 | |
| 11304 | * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c, |
| 11305 | memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c, |
| 11306 | strtoul.c. |
| 11307 | * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4, |
| 11308 | hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4, |
| 11309 | xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4, |
| 11310 | inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4, |
| 11311 | stdint_h.m4, uintmax_t.m4, ulonglong.m4. |
| 11312 | * src/.cvsignore: Add *.output. |
| 11313 | |
| 11314 | * src/parse-gram.y: Put copyright notice inside %{ %} so it |
| 11315 | gets copied to the output file. |
| 11316 | |
| 11317 | 2004-04-28 Paul Eggert <eggert@twinsun.com> |
| 11318 | |
| 11319 | Get files from the gnulib and po repositories, instead of relying |
| 11320 | on them being in our CVS. Upgrade to latest versions of gnulib |
| 11321 | and Automake. |
| 11322 | |
| 11323 | * Makefile.am (SUBDIRS): Remove m4; Automake now does m4. |
| 11324 | * bootstrap: Bootstrap from gnulib and po repositories. |
| 11325 | Much of this code was stolen from GNU diff and GNU tar's bootstrap. |
| 11326 | * README-cvs: Document these changes. Remove version numbers from |
| 11327 | mentions of build tools, since they change so often. Mention Flex. |
| 11328 | |
| 11329 | * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg. |
| 11330 | (gl_USE_SYSTEM_EXTENSIONS): Add. |
| 11331 | (AC_GNU_SOURCE, AC_AIX, AC_MINIX): |
| 11332 | Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS |
| 11333 | does this for us. |
| 11334 | (AC_ISC_POSIX): Remove; we no longer support this |
| 11335 | ancient OS, as it gets in the way of latest Autoconf & gnulib. |
| 11336 | (AC_HEADER_STDC): Remove: we now assume C89 or better. |
| 11337 | (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS. |
| 11338 | Do not check for C89 headers, except for locale.h which is used |
| 11339 | by the Yacc library and must port to K&R hosts. |
| 11340 | (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS. |
| 11341 | Do not check for C89 functions, except for setlocale which is |
| 11342 | used by the Yacc library. |
| 11343 | (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed. |
| 11344 | (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR, |

| 11347 | gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC, |
| 11348 | AM_GNU_GETTEXT): Remove; now done by: |
| 11349 | (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us. |
| 11350 | (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this |
| 11351 | for us. |
| 11352 | |
| 11353 | * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap". |
| 11354 | (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): |
| 11355 | Define to empty, as gnulib.mk will do the rest for us. |
| 11356 | ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this |
| 11357 | for us. |
| 11358 | (libbison_a_SOURCES): Define to $(lib_SOURCES) now. |
| 11359 | (lib_SOURCES): New symbol, containing only the non-gnulib libs. |
| 11360 | |
| 11361 | * src/files.c: Include gnulib's xstrndup.h. |
| 11362 | |
| 11363 | * src/system.h (MALLOC): Use xnmalloc, for better overflow checking. |
| 11364 | (REALLOC): Use xnrealloc, for likewise. |
| 11365 | (xstrndup, stpcpy): Remove decls, as gnulib does this for us now. |
| 11366 | (strnlen, memrchr): Remove decls; functions no longer used. |
| 11367 | Include <stpcpy.h>. |
| 11368 | |

| 11392 | |
| 11393 | * po/ChangeLog: Remove: all but one entry was a duplicate |
| 11394 | of this file, and I moved that 2000-11-02 entry here. |
| 11395 | |
| 11396 | * config/.cvsignore: Add Makefile, depcomp, install-sh. |

| 11414 | |
| 11415 | |
| 11416 | * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't |
| 11417 | support it. (The latest stable gzip doesn't.) |
| 11418 | |
| 11419 | 2004-04-27 Paul Eggert <eggert@twinsun.com> |
| 11420 | |
| 11421 | * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this |
| 11422 | case, as stos_ is now used by destructors due to the 2004-02-09 |
| 11423 | change. |
| 11424 | |
| 11425 | Remove more K&R C support. |
| 11426 | * lib/libiberty.y (PARAMS): Remove. All uses removed. |
| 11427 | * lib/subpipe.c (errno): Remove decl. |
| 11428 | Include <stdlib.h> unconditionally. |

| 11435 | (strchr, strspn, memchr): Remove decls. |
| 11436 | * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h |

| 11445 | * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args |

| 11448 | |
| 11449 | * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>, |
| 11450 | so that this include file can stand alone. |
| 11451 | * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h |
| 11452 | does this now. Include subpipe.h first after config.h, to |
| 11453 | test whether it can stand alone. |
| 11454 | |
| 11455 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't |
| 11456 | declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the |
| 11457 | unused declaration. |
| 11458 | |
| 11459 | * tests/synclines.at (%union synch line): Put a dummy member in |
| 11460 | the union, because empty unions aren't allowed in C. Caught |
| 11461 | by GCC 3.4.0. |
| 11462 | |
| 11463 | 2004-04-13 Jim Meyering <jim@meyering.net> |
| 11464 | |
| 11465 | * src/conflicts.c (conflicts_print): Correct format string typo: |

| 11467 | |
| 11468 | 2004-03-30 Paul Eggert <eggert@twinsun.com> |
| 11469 | |
| 11470 | * src/getargs.c (version): Update copyright year to 2004. |
| 11471 | |
| 11472 | * data/c.m4 (b4_int_type): Use 'short int' rather than |
| 11473 | 'short', and similarly for 'long', 'unsigned', etc. |
| 11474 | * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum, |
| 11475 | yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError, |
| 11476 | yy_yypstack, yydumpstack): Likewise. |
| 11477 | * data/lalr1.cc (user_token_number_max_, user_token_number_max_, |
| 11478 | translate_, seq_, [], pop, Slice, range_, operator+, operator+=): |
| 11479 | Likewise. |

| 11533 | Add support for hex token numbers. Suggested by Odd Arild Olsen in |
| 11534 | <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>. |
| 11535 | |

| 11547 | |
| 11548 | * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from |

| 11550 | chatty, reported by Guido Trentalancia in |

| 11567 | token so that it covers all the discarded tokens. |

| 11572 | |
| 11573 | * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions |
| 11574 | $(top_srcdir)/lib and ../lib. This fixes a bug reported |
| 11575 | by Paul Hilfinger; the old INCLUDES value didn't mention ../lib. |
| 11576 | There's no need to mention top_builddir since Automake does that |
| 11577 | for us. |

| 11597 | * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in |
| 11598 | Bison tokens, as this runs afoul of the 2003-10-07 change that |
| 11599 | disallowed NUL bytes in character constants or string literals. |
| 11600 | |
| 11601 | * tests/local.at: Require Autoconf 2.59's Autotest. |
| 11602 | * tests/testsuite.at: Don't include local.at, since we now assume |
| 11603 | Autoconf 2.59 or later. Autoconf 2.59 had some problems with |

| 11702 | |
| 11703 | When reducing initial empty rules, Bison parser read an initial |
| 11704 | location that is not defined. This results in garbage, and that |
| 11705 | affects Bison's own parser. Therefore we need (i) to extend Bison |
| 11706 | to support a means to initialize this location, and (ii) to use |
| 11707 | this CVS Bison to fix CVS Bison's parser. |
| 11708 | |
| 11709 | * src/reader.h, reader.c (epilogue_augment): Remove, replace |
| 11710 | with... |
| 11711 | * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this. |
| 11712 | * src/parse-gram.y: Adjust. |
| 11713 | (%initial-action): New. |
| 11714 | (%error-verbose): Since we require CVS Bison, there is no reason |
| 11715 | not to use it. |
| 11716 | * src/scan-gram.l: Adjust. |
| 11717 | * src/Makefile.am (YACC): New, to make sure we use our own parser. |
| 11718 | * data/yacc.c (yyparse): Use b4_initial_action. |

| 11720 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 11721 | |

| 11744 | |
| 11745 | Have lalr1.cc catch with Paul Eggert's patch to fix the infinite |
| 11746 | error recovery loops. This patch is based on |
| 11747 | <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>. |
| 11748 | Also, augment the similarity between lalr1.cc and yacc.c. |
| 11749 | Note: the locations of error recovery rules are not correct yet. |
| 11750 | |
| 11751 | * data/lalr1.cc: Comment changes to augment the similarity between |
| 11752 | lalr1.cc and yacc.c. |
| 11753 | (YYERROR): Goto to yyerrorlab, not yyerrlab1. |
| 11754 | (yyerrlab1): Remove, but where it used to be (now the bottom part of |
| 11755 | yyerrlab), when hitting EOF, pop the whole stack here instead of |
| 11756 | merely falling thru the default error handling mechanism. |
| 11757 | (yyerrorlab): New label, with the old contents of YYERROR, |
| 11758 | plus the following change: pop the stack of rhs corresponding |
| 11759 | to the production that invoked YYERROR. That is how Yacc |
| 11760 | behaves (required by POSIX). |
| 11761 | * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to |
| 11762 | fail. |
| 11763 | |
| 11764 | 2003-08-25 Akim Demaille <akim@epita.fr> |
| 11765 | |
| 11766 | Tune local.at so that people can "autom4te -l autotest calc.at -o |
| 11767 | calc" for instance, to extract a sub test suite. |
| 11768 | |
| 11769 | * tests/testsuite.at: Move the initialization, Autotest version |
| 11770 | requirement, and AT_TESTED invocation into... |
| 11771 | * tests/local.at: here. |
| 11772 | * tests/testsuite.at: Include it for compatibility with Autoconf |
| 11773 | 2.57. |
| 11774 | * tests/Makefile.am ($(TESTSUITE)): Report that the warning should |
| 11775 | be ignore. |
| 11776 | |
| 11777 | 2003-08-04 Paul Eggert <eggert@twinsun.com> |
| 11778 | |
| 11779 | Rework code slightly to avoid gcc -Wtraditional warnings. |
| 11780 | * data/glr.c (yyuserMerge): Return void, not YYSTYPE. |
| 11781 | The returned value is now stored in *YY0. All callers changed. |
| 11782 | * src/output.c (merge_output): Adjust to the above change. |

| 11784 | 2003-07-26 Paul Eggert <eggert@twinsun.com> |

| 11787 | (yyfillin, yydoAction, yyglrReduce, yysplitStack, |
| 11788 | yyresolveStates, yyprocessOneStack): |
| 11789 | Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'. |
| 11790 | Derived from a suggestion by Frank Heckenbach. |
| 11791 | |
| 11792 | 2003-07-25 Paul Eggert <eggert@twinsun.com> |
| 11793 | |
| 11794 | * data/glr.c (yyglrReduce): Don't use C89 string concatenation, |
| 11795 | for portability to K&R C (after ansi2knr, presumably). See |
| 11796 | <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html> |
| 11797 | by Frank Heckenbach, though I have omitted the structure-initialization |
| 11798 | part of his glr-knr.diff patch since I recall that the Portable |
| 11799 | C Compiler didn't require that change. |
| 11800 | |
| 11801 | Let the user specify how to allocate and free memory. |
| 11802 | Derived from a suggestion by Frank Heckenbach in |

| 11804 | * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros. |
| 11805 | All uses of free, malloc, realloc changed to use these macros, |
| 11806 | and unnecessary casts removed. |
| 11807 | * data/yacc.c (YYFREE, YYMALLOC): Likewise. |

| 11810 | |
| 11811 | * data/lalr1.cc (operator<<(std::ostream&, const Position&)): |

| 11833 | yyreportTree): Do not assume that size_t is the same width as int, |
| 11834 | when printing sizes. Print sizes using an unsigned format. |
| 11835 | Problem reported by Frank Heckenbach in |
| 11836 | <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>. |
| 11837 | |
| 11838 | Port to Forte Developer 7 C compiler. |
| 11839 | * data/glr.c (struct YYLTYPE): If locations are not being used, |
| 11840 | declare a single dummy member, as empty structs do not conform |
| 11841 | to the C standard. |
| 11842 | (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)"; |
| 11843 | the Forte Developer 7 C compiler complains that end-of-loop |
| 11844 | code is not reached. |

| 11847 | |
| 11848 | * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to |
| 11849 | avoid warnings from picky compilers about redefinition of PARAMS. |

| 11854 | |
| 11855 | * NEWS: Document 1.875b. |
| 11856 | |
| 11857 | * lib/bbitset.h: Do not include config.h; that's the includer's job. |
| 11858 | Do not include <sys/types.h>; shouldn't be needed on a C89 host. |
| 11859 | * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard. |
| 11860 | Don't use 'index' in comments, as it's a builtin fn on some hosts. |

| 11862 | per recent gettext manual's suggestion. |
| 11863 | * lib/ebitset.c (ebitset_resize, ebitset_unused_clear): |

| 11880 | Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in: |
| 11881 | <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html> |
| 11882 | * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h. |
| 11883 | * lib/vbitset.c, lib/vbitset.h: New files. |
| 11884 | * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h, |
| 11885 | lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import |
| 11886 | from libbitset. |
| 11887 | |
| 11888 | * doc/bison.texinfo (How Can I Reset the Parser): Renamed from |
| 11889 | `How Can I Reset @code{yyparse}', since texinfo does not allow |
| 11890 | arbitrary @ in node names. |
| 11891 | |
| 11892 | * m4/Makefile.am (EXTRA_DIST): Add the following files, which |
| 11893 | shouldn't be needed according to the gettext 0.12.1 documentation |
| 11894 | but which seem to be needed anyway: codeset.m4 glibc21.m4 |
| 11895 | intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4 |
| 11896 | lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4. |

| 11898 | |
| 11899 | * lib/.cvsignore: Add stdbool.h. |
| 11900 | * m4/.cvsignore: Add nls.m4, po.m4. |
| 11901 | |
| 11902 | Upgrade to CVS gnulib. |
| 11903 | * stdbool_.h: File renamed from stdbool.h.in. |
| 11904 | * configure.ac (AM_STDBOOL_H): Invoke this instead of |
| 11905 | AC_HEADER_STDBOOL. |
| 11906 | (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests. |
| 11907 | (AM_GNU_GETTEXT_VERSION): Update to 0.12.1. |
| 11908 | * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h. |
| 11909 | (MOSTLYCLEANFILES): New var. |
| 11910 | ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H). |
| 11911 | (stdbool.h): New rule. |
| 11912 | * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h, |
| 11913 | lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c, |
| 11914 | lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4, |
| 11915 | m4/quote.m4: Upgrade to today's gnulib. |

| 11917 | * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL. |
| 11918 | (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails |
| 11919 | the tests right now. |
| 11920 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and |
| 11921 | yyerror are declared before use; C99 requires this. |
| 11922 | |
| 11923 | 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 11924 | |
| 11925 | * data/glr.c (YYERROR): Update definition to reset yyerrState to 0 |
| 11926 | first. |
| 11927 | (yyrecoverSyntaxError): Correct the logic for setting and testing |
| 11928 | yyerrState. |
| 11929 | Correct comment on handling EOF. |
| 11930 | Allow states with only a default reduction, rather than failing |
| 11931 | (I can't quite reconstruct why these were not allowed before). |
| 11932 | |
| 11933 | Fixes to avoid problem that $-N rules in GLR parsers can cause |
| 11934 | buffer overruns, corrupting state. |
| 11935 | |
| 11936 | * src/output.c (prepare_rules): Output max_left_semantic_context |
| 11937 | definition. |
| 11938 | * src/reader.h (max_left_semantic_context): New variable declaration. |
| 11939 | * src/scan-gram.l (max_left_semantic_context): Define. |

| 11944 | |
| 11945 | Fixes to problems with location handling in GLR parsers reported by |
| 11946 | Frank Heckenbach (2003/06/05). |
| 11947 | |
| 11948 | * data/glr.c (YYLTYPE): Make trivial if locations not used. |
| 11949 | (YYRHSLOC): Add parentheses, and define only if locations used. |
| 11950 | (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if |
| 11951 | locations not used. |
| 11952 | (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp. |
| 11953 | (yydoAction): Remove redundant initialization of *yyvalp and *yylocp. |
| 11954 | |
| 11955 | * tests/cxx-type.at: Exercise location information; update tests |
| 11956 | to differentiate output with and without locations. |
| 11957 | Remove forward declarations of yylex and yyerror---caused errors |
| 11958 | because default YYLTYPE not yet defined. |
| 11959 | Change semantic actions to compute strings, rather than printing |
| 11960 | them directly (to test proper passing of semantics values). Change |
| 11961 | output to prefix notation and update test data and expected results. |
| 11962 | (yylex): Track locations. |
| 11963 | (stmtMerge): Return value rather than printing, and include arguments |
| 11964 | in value. |
| 11965 | |

| 11967 | |
| 11968 | Avoid warnings generated by GCC 2.95.4 when Bison is |
| 11969 | configured with --enable-gcc-warnings. |
| 11970 | * data/lalr1.cc (yy::]b4_parser_class_name[::parse, |
| 11971 | yy::]b4_parser_class_name[::translate_, |
| 11972 | yy::Stack::operator[] (unsigned), |
| 11973 | yy::Stack::operator[] (unsigned) const, |
| 11974 | yy::Slice::operator[] (unsigned), |
| 11975 | yy::Slice::operator[] (unsigned) const): |
| 11976 | Rename local vars to avoid warnings. |
| 11977 | * tests/glr-regression.at (Improper handling of embedded actions |
| 11978 | and $-N in GLR parsers): Remove unused local variable from yylex. |
| 11979 | * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take |
| 11980 | (void) as arg when not pure, since we now assume C89 when building |
| 11981 | Bison. Pacify GCC by using parameter. |
| 11982 | |
| 11983 | 2003-06-02 Paul Eggert <eggert@twinsun.com> |
| 11984 | |
| 11985 | * data/lalr1.cc (yy::Position::lines, yy::Position::columns, |
| 11986 | yy::Location::lines, yy::Location::columns): Rename arguments |
| 11987 | to avoid shadowing; this removes a warning generated by GCC 3.3. |
| 11988 | |
| 11989 | 2003-06-01 Paul Eggert <eggert@twinsun.com> |
| 11990 | |
| 11991 | Don't pass C-only warning optins (e.g., -Wmissing-declarations) |
| 11992 | to g++, as GCC 3.3 complains if you do it. |
| 11993 | * configure.ac (WARNING_CXXFLAGS): New subst. Set it to |
| 11994 | everything that WARNING_CFLAGS has, except omit warnings |
| 11995 | not suitable for C++. |
| 11996 | (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]). |
| 11997 | * tests/atlocal.in (CXXFLAGS): New var. |
| 11998 | * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS. |
| 11999 | |
| 12000 | Fix a GLR parser bug I reported in February; see |
| 12001 | <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>. |
| 12002 | The problem was that GLR parsers did not conform to the C standard, |
| 12003 | because actions like { $1 = $2 + $3; } expanded to expressions |
| 12004 | that invoked YYFILL in separate subexpressions, and YYFILL assigned |
| 12005 | to a local variable. The C standard says that expressions |
| 12006 | like (var = f ()) + (var = f ()) have undefined behavior. |
| 12007 | Another problem was that GCC sometimes issues warnings that |
| 12008 | yyfill and its parameters are unused. |
| 12009 | |
| 12010 | * data/glr.c (yyfillin): Renamed from the old yyfill. Mark |
| 12011 | as possibly unused. |
| 12012 | (yyfill): New function. |
| 12013 | (YYFILL): Use it. |
| 12014 | (yyuserAction): Change type of yynormal to bool, so that it matches |
| 12015 | the new yyfill signature. Mark it as possibly unused. |
| 12016 | |
| 12017 | |
| 12018 | Follow up on a bug I reported in February, where a Bison-generated |
| 12019 | parser can loop. Provide a test case and a fix for yacc.c. I |
| 12020 | don't have a fix for lalr1.cc or for glr.c, unfortunately. |
| 12021 | The original bug report is in: |
| 12022 | <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html> |
| 12023 | |
| 12024 | * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the |
| 12025 | macro's size was becoming unwieldy. |
| 12026 | (yyerrlab): Do not discard an empty lookahead symbol, as this |
| 12027 | might destroy garbage. |
| 12028 | (yyerrorlab): New label, with the old contents of YYERROR, |
| 12029 | plus the following change: pop the stack of rhs corresponding |
| 12030 | to the production that invoked YYERROR. That is how Yacc |
| 12031 | behaves, and POSIX requires this behavior. |
| 12032 | (yyerrlab1): Use YYPOPSTACK instead of its definiens. |
| 12033 | * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available. |
| 12034 | Define 'alarm' to do nothing if unistd.h is not available. |
| 12035 | Add a new rule "exp: '-' error;" to test the above change to |
| 12036 | data/yacc.c. Use 'alarm' to abort any test taking longer than |
| 12037 | 10 seconds, as it's probably looping. |
| 12038 | (AT_CHECK_CALC): Test recovery from error in new grammar rule. |
| 12039 | Also, the new yacc.c generates two fewer diagnostics for an |
| 12040 | existing test. |
| 12041 | |
| 12042 | 2003-05-24 Paul Eggert <eggert@twinsun.com> |
| 12043 | |
| 12044 | * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate |
| 12045 | YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined. |
| 12046 | This fixes a problem reported by John Bowman when the Compaq/HP |
| 12047 | Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM |
| 12048 | -ansi -Wall -gall). |
| 12049 | * data/yacc.c (union yyalloc): Likewise. |
| 12050 | (YYCOPY): Do not evaluate __GNUC__ unless it is defined. |
| 12051 | |
| 12052 | Switch from 'int' to 'bool' where that makes sense. |
| 12053 | |
| 12054 | * lib/abitset.c (abitset_test, abitset_empty_p, abitset_equal_p, |

| 12079 | * lib/bbitset.h: Include <stdbool.h>. |

| 12116 | |
| 12117 | * src/parse-gram.y (rules_or_grammar_declaration): Require a |

| 12127 | |
| 12128 | %parse-param support for lalr1.cc. |
| 12129 | |
| 12130 | * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons, |
| 12131 | b4_cc_constructor_calls, b4_cc_constructor_call, |
| 12132 | b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4 |

| 12138 | * tests/calc.at: s/value/semantic_value/ because value clashes |
| 12139 | with a member of yy::b4_parser_class_name. Adjust C++ code |
| 12140 | to handle %parse-param. Enable %parse-param test in C++. |
| 12141 | |
| 12142 | 2003-05-12 Paul Eggert <eggert@twinsun.com> |
| 12143 | |
| 12144 | * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the |
| 12145 | English a bit. Fix fclose typo. Change "const char" to "char |
| 12146 | const", and use ANSI C rather than K&R for "main". Suggest |
| 12147 | YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends) |

| 12150 | 2003-05-05 Paul Eggert <eggert@twinsun.com> |
| 12151 | |
| 12152 | * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes |
| 12153 | C89. This avoids a diagnostic on compilers that define __STDC__ |
| 12154 | to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in |
| 12155 | <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>. |

| 12158 | |
| 12159 | * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE): |
| 12160 | Do not overrun array bounds. |
| 12161 | This should fix a bug reported today by Olatunji Oluwabukunmi in |
| 12162 | <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>. |
| 12163 | |
| 12164 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 12165 | |
| 12166 | * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to... |
| 12167 | * src/getargs.c, src/getargs.h: here, as bool, not int. |
| 12168 | (nondeterministic_parser): New. |
| 12169 | * src/parse-gram.y, src/scan-gram.l: Support |
| 12170 | %nondeterministic-parser. |
| 12171 | * src/output.c (prepare): Use nondeterministic_parser instead |
| 12172 | of glr_parser where appropriate. |
| 12173 | * src/tables.c (conflict_row, action_row, save_row) |
| 12174 | (token_actions, token_actions, pack_vector): Ditto. |
| 12175 | |
| 12176 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 12177 | |
| 12178 | * doc/bison.texinfo (C++ Parsers, Implementing Loops): New. |
| 12179 | |
| 12180 | 2003-04-29 Akim Demaille <akim@epita.fr> |
| 12181 | |
| 12182 | * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet) |
| 12183 | with %pure-parser and %locations to exercise the patch from Yakov |
| 12184 | Markovitch below. |
| 12185 | |
| 12186 | 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be> |
| 12187 | |
| 12188 | * data/yacc.c: (b4_lex_param): Corrected for the case where |
| 12189 | %lex-param is provided and %pure-parser isn't. |
| 12190 | |
| 12191 | 2003-04-27 Paul Eggert <eggert@twinsun.com> |
| 12192 | |
| 12193 | Avoid gcc -Wundef warnings reported by Gerald Pfeifer in |
| 12194 | <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>. |
| 12195 | * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA |
| 12196 | if it is not defined. |
| 12197 | (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined. |
| 12198 | |
| 12199 | 2003-04-26 Paul Eggert <eggert@twinsun.com> |
| 12200 | |
| 12201 | * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_): |
| 12202 | Declare to be of type suitable for the ninf value itself, not of |
| 12203 | type suitable for the corresponding table, since the latter might |
| 12204 | be unsigned but the ninf value might be negative. This fixes a |
| 12205 | bug reported by Alexandre Duret-Lutz in |
| 12206 | <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>. |
| 12207 | |
| 12208 | * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR |
| 12209 | invokes it. We shouldn't invoke it twice because it will attempt |
| 12210 | to put error.o in the archive twice. This fixes a glitch reported |
| 12211 | by Martin Mokrejs in |
| 12212 | <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>. |
| 12213 | |
| 12214 | 2003-04-21 Paul Eggert <eggert@twinsun.com> |
| 12215 | |
| 12216 | * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch |
| 12217 | to gnulib. |
| 12218 | |
| 12219 | 2003-04-21 Yakov Markovitch <Markovitch@iso.ru> |
| 12220 | |
| 12221 | * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]: |
| 12222 | Fix obvious typo that results in uncompilable GLR parsers |
| 12223 | when both %pure-parser and %locations are used. (trivial change) |
| 12224 | |
| 12225 | 2003-04-17 Paul Eggert <eggert@twinsun.com> |
| 12226 | |
| 12227 | * src/scan-gram.l: Add %option nounput, since we no longer use unput. |
| 12228 | (unexpected_eof): Renamed from unexpected_end_of_file, for brevity. |
| 12229 | Do not insert the expected token via unput, as this runs afoul |
| 12230 | of a POSIX-compatibility bug in flex 2.5.31. |
| 12231 | All uses changed to BEGIN the parent state, |
| 12232 | since we no longer insert the expected token via unput. |
| 12233 | * tests/regression.at (Invalid inputs): Remove cascaded diagnostic |
| 12234 | that is no longer emitted after the above change. |
| 12235 | |
| 12236 | * src/conflicts.c (set_conflicts): Resolve all conflicts, not just |
| 12237 | the first one. This change is from Paul Hilfinger, and it fixes |
| 12238 | regression reported by Werner Lemberg in |
| 12239 | <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>. |
| 12240 | |
| 12241 | (resolve_sr_conflict): Don't invoke state_errs_set |
| 12242 | unless one or more tokens have been explicitly made errors. |
| 12243 | Otherwise, the above change causes Bison to abort. |
| 12244 | |
| 12245 | * tests/existing.at (GNU pic Grammar): New test case, taken from |
| 12246 | Lemberg's email. |
| 12247 | |
| 12248 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 12249 | |
| 12250 | * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file. |
| 12251 | |
| 12252 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 12253 | |
| 12254 | * src/output.c (prepare_symbols): Avoid trailing spaces in the |
| 12255 | output. |
| 12256 | |
| 12257 | 2003-03-31 Akim Demaille <akim@epita.fr> |
| 12258 | |
| 12259 | * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/. |
| 12260 | From Paul Hilfinger. |
| 12261 | |
| 12262 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 12263 | |
| 12264 | * m4/error.m4: Do not put under dynamic conditions some code which |
| 12265 | expansion is under static control. |
| 12266 | |
| 12267 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 12268 | |
| 12269 | * doc/bison.texinfo (How Can I Reset @code{yyparse}): New. |
| 12270 | |
| 12271 | 2003-03-29 Akim Demaille <akim@epita.fr> |
| 12272 | |
| 12273 | * doc/bison.texinfo (Strings are Destroyed): New. |
| 12274 | |
| 12275 | 2003-03-13 Paul Eggert <eggert@twinsun.com> |
| 12276 | |
| 12277 | * .cvsignore: Add configure.lineno. |
| 12278 | * src/.cvsignore: Add yacc. |
| 12279 | * tests/.cvsignore: Add testsuite.log. |
| 12280 | * doc/fdl.texi: Sync with latest FSF version. |
| 12281 | |
| 12282 | 2003-03-12 Paul Eggert <eggert@twinsun.com> |
| 12283 | |
| 12284 | * scan-gram.l (YY_USER_INIT): Initialize code_start, too. |
| 12285 | (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner |
| 12286 | cursor, instead of leaving it undefined. This fixes a bug |
| 12287 | reported by Tim Van Holder in |
| 12288 | <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>. |
| 12289 | * tests/input.at (Torturing the Scanner): Test the scanner on |
| 12290 | an empty input file, which was Tim Van Holder's test case. |
| 12291 | |
| 12292 | * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether |
| 12293 | <sys/resource.h> can be included, include sys/time.h and |
| 12294 | sys/times.h first, if available. This works around the SunOS |
| 12295 | 4.1.4 porting bug reported by Bruce Becker in |
| 12296 | <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>. |
| 12297 | |
| 12298 | * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't |
| 12299 | AC_CHECK_HEADERS([sys/wait.h]), as this interferes with |
| 12300 | AC_HEADER_SYS_WAIT. |
| 12301 | |
| 12302 | Merge changes from gnulib. This was prompted because the CVS |
| 12303 | snapshot didn't build on Solaris 7 due to strnlen problems. |
| 12304 | |
| 12305 | These changes need to be merged back into gnulib: |
| 12306 | * lib/hash.c: Include <stdbool.h> unconditionally. |
| 12307 | * m4/onceonly.m4 (m4_quote): New macro. |
| 12308 | (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE): |
| 12309 | Quote AC_FOREACH variable-expansions properly. |
| 12310 | The 2003-01-03 obstack.h change also needs merging. |
| 12311 | {end of changes requiring merging} |
| 12312 | |
| 12313 | * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4, |
| 12314 | m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4, |

| 12317 | m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4: |
| 12318 | New files, imported from gnulib. |
| 12319 | * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned |
| 12320 | above. |
| 12321 | |
| 12322 | * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4, |
| 12323 | m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current |
| 12324 | gnulib sources. |
| 12325 | |
| 12326 | * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC): |
| 12327 | Add. |
| 12328 | (gl_ERROR): New, replacing jm_PREREQ_ERROR. |
| 12329 | (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA. |
| 12330 | (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy). |
| 12331 | (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN. |
| 12332 | (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH. |
| 12333 | (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK. |
| 12334 | (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG. |
| 12335 | (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New. |
| 12336 | (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC. |
| 12337 | (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC. |
| 12338 | (jm_PREREQ_ARGMATCH): Remove. |
| 12339 | (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul. |
| 12340 | * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h. |
| 12341 | |
| 12342 | * src/system.h: Include <stdbool.h> unconditionally. |
| 12343 | |
| 12344 | * lib/bbitset.h: Include <limits.h> unconditionally. We have been |
| 12345 | assuming at least C89 in the bitset code for some time now. |
| 12346 | |
| 12347 | 2003-03-03 Akim Demaille <akim@epita.fr> |
| 12348 | |
| 12349 | * ro.po: New. |
| 12350 | |
| 12351 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 12352 | |
| 12353 | * doc/bison.texinfo (Table of Symbols): Reactivate the |
| 12354 | documentation for %lex-param, and %parse-param. |
| 12355 | |
| 12356 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 12357 | |
| 12358 | * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to |
| 12359 | generate verbose error messages. |
| 12360 | Use the number of tokens as an upper bound in yytname, as it |
| 12361 | cannot be a non terminal. |
| 12362 | |
| 12363 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 12364 | |
| 12365 | * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error |
| 12366 | message. |
| 12367 | |
| 12368 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 12369 | |
| 12370 | * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New. |
| 12371 | Use them to exercise yycheck overrun. |
| 12372 | Based on Andrew Suffield's grammar. |
| 12373 | |
| 12374 | 2003-03-02 Akim Demaille <akim@epita.fr> |
| 12375 | |
| 12376 | Create tests/local.at for Bison generic testing macros. |
| 12377 | |
| 12378 | * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to... |
| 12379 | * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): |
| 12380 | This new file. |
| 12381 | * tests/calc.at (AT_CHECK_CALC): Adjust. |
| 12382 | * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR) |
| 12383 | (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to... |
| 12384 | * tests/local.at: here. |
| 12385 | (AT_COMPILE_CXX): Tags the tests using it as c++. |
| 12386 | Ignore the test if CXX is not functional. |
| 12387 | |
| 12388 | 2003-03-01 Paul Eggert <eggert@twinsun.com> |
| 12389 | |
| 12390 | * src/scan-gram.l (code_start): Initialize it to scanner_cursor, |
| 12391 | not loc->end, since loc->end might contain garbage and this leads |
| 12392 | to undefined behavior on some platforms. |
| 12393 | (id_loc, token_start): Use (IF_LINTed) initial values that do not |
| 12394 | depend on *loc, so that the reader doesn't give the the false |
| 12395 | impression that *loc is initialized. |
| 12396 | (<INITIAL>"%%"): Do not bother setting code_start, since its value |
| 12397 | does not survive the return. |
| 12398 | |
| 12399 | 2003-03-01 Akim Demaille <akim@epita.fr> |
| 12400 | |
| 12401 | * src/scan-gram.l (code_start): Always initialize it when entering |
| 12402 | into yylex, as SC_EPILOGUE is activated *before* the corresponding |
| 12403 | yylex invocation. An alternative would be making it static, but |
| 12404 | then it starts with the second %%'s beginning, instead of its end. |
| 12405 | |
| 12406 | 2003-02-28 Paul Eggert <eggert@twinsun.com> |
| 12407 | |
| 12408 | * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work |
| 12409 | around a UnixWare 7.1.1 porting bug reported by John Hughes in |
| 12410 | <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>. |
| 12411 | |
| 12412 | 2003-02-26 Paul Eggert <eggert@twinsun.com> |
| 12413 | |
| 12414 | * README: Mention compiler bug in Sun Forte Developer 6 update 2. |
| 12415 | Remove Sequent/Pyramid discussion (nobody uses them any more). |
| 12416 | Merge VMS and MS-DOS discussion; these ports may well be dead |
| 12417 | but let's keep mentioning them for now. Put <> around email |
| 12418 | addresses. Add copyright notice. |
| 12419 | |
| 12420 | 2003-02-24 Paul Eggert <eggert@twinsun.com> |
| 12421 | |
| 12422 | * data/glr.c (yy_reduce_print): yylineno -> yylno, |
| 12423 | to avoid collision with flex use of yylineno. |
| 12424 | Problem reported by Bruce Lilly in |
| 12425 | <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>. |
| 12426 | * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise. |
| 12427 | * data/yacc.c (yy_reduce_print): Likewise. |
| 12428 | |
| 12429 | * config/depcomp: Sync with Automake 1.7.3. |
| 12430 | |
| 12431 | 2003-02-21 Akim Demaille <akim@epita.fr> |
| 12432 | |
| 12433 | * data/lalr1.cc: Use temporary variables instead of casts to |
| 12434 | change integer types. |
| 12435 | Suggested by Paul Eggert. |
| 12436 | |
| 12437 | 2003-02-21 Akim Demaille <akim@epita.fr> |
| 12438 | |
| 12439 | * doc/bison.texinfo: Use "location" consistently to refer to @n, |
| 12440 | to avoid confusions with lalr1.cc's notion of Position. |
| 12441 | Suggested by Paul Eggert. |
| 12442 | |
| 12443 | 2003-02-20 Akim Demaille <akim@epita.fr> |
| 12444 | |
| 12445 | * data/lalr1.cc (position.hh): Make sure "columns" never pushes |
| 12446 | before initial_columns. |
| 12447 | (location.hh): Use consistent variable names when defining the |
| 12448 | operator<<. |
| 12449 | Use "last" so that we subtract from Positions, not from unsigned. |
| 12450 | |
| 12451 | 2003-02-20 Akim Demaille <akim@epita.fr> |
| 12452 | |
| 12453 | * data/lalr1.cc (position.hh): New subfile, including the extended |
| 12454 | and Doxygen'ed documentation of class Position. |
| 12455 | (location.hh): Use it. |
| 12456 | Document a` la Doxygen. |
| 12457 | With the help of Benoit Perrot. |
| 12458 | |
| 12459 | 2003-02-20 Akim Demaille <akim@epita.fr> |
| 12460 | |
| 12461 | * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define |
| 12462 | AT_YACC_IF. |
| 12463 | Redefine AT_YYERROR_SEES_LOC_IF using it. |
| 12464 | (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is |
| 12465 | not defined. |
| 12466 | Don't use the location in yy::Parser::error_ and |
| 12467 | yy::Parser::print_ when not %locations. |
| 12468 | Activate more lalr1.cc tests. |
| 12469 | |
| 12470 | 2003-02-19 Akim Demaille <akim@epita.fr> |
| 12471 | |
| 12472 | * data/lalr1.cc: When displaying a line number, be sure to make it |
| 12473 | an int. |
| 12474 | |
| 12475 | 2003-02-19 Akim Demaille <akim@epita.fr> |
| 12476 | |
| 12477 | * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_): |
| 12478 | Remove, useless. |
| 12479 | (YYABORT, YYACCEPT, YYERROR): New. |
| 12480 | * tests/calc.at: Renable the lalr1.cc test. |
| 12481 | |
| 12482 | 2003-02-19 Akim Demaille <akim@epita.fr> |
| 12483 | |
| 12484 | * tests/calc.at (AT_CHECK_CALC): Check different scenarios of |
| 12485 | error recovery, mixing with/without pops and discarding of the |
| 12486 | lookahead. |
| 12487 | Exercise YYERROR. |
| 12488 | Disable the lalr1.cc tests as currently it doesn't support YYERROR. |
| 12489 | |
| 12490 | 2003-02-17 Paul Eggert <eggert@twinsun.com> |
| 12491 | |
| 12492 | * tests/atlocal.in (LDFLAGS, LIBS): New vars. |
| 12493 | * tests/testsuite.at (AT_COMPILE): Use them. |
| 12494 | This fixes the testsuite problem reported by Robert Lentz in |
| 12495 | <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>. |

| 12498 | |
| 12499 | * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]: |
| 12500 | Avoid subscript error in yycheck. Bug reported by Andrew Suffield in |
| 12501 | <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>. |
| 12502 | * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise. |
| 12503 | Check for malloc failure, for consistency with yacc.c. |
| 12504 | (yytname_size): Remove, for consistency with yacc.c. |
| 12505 | |
| 12506 | The bug still remains in data/lalr1.cc, as I didn't have time |
| 12507 | to fix it there. |
| 12508 | |
| 12509 | 2003-02-06 Akim Demaille <akim@epita.fr> |
| 12510 | |
| 12511 | * configure.ac (GXX): Rename as... |
| 12512 | (CXX): this, to keep the original Autoconf semantics. |
| 12513 | Require 2.57. |
| 12514 | * data/lalr1.cc: Fix b4_copyright invocations. |
| 12515 | If YYDEBUG is not defined, don't depend upon name_ being defined. |
| 12516 | (location.hh): Include string and iostream. |
| 12517 | (Position::filename): New member. |
| 12518 | (Position::Position ()): New. |

| 12523 | iterator names. |
| 12524 | (operator<< (Location)): New. |
| 12525 | * tests/atlocal.in (CXX): New. |
| 12526 | * tests/testsuite.at (AT_COMPILE_CXX): New. |
| 12527 | * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the |
| 12528 | locations in a more synthetic way. |
| 12529 | (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if |
| 12530 | lalr1.cc is used. |
| 12531 | Adjust the C locations to match those from Emacs: first column is |
| 12532 | column 0. |
| 12533 | Change all the expected results. |
| 12534 | Conform to the GCS: simplify the locations when applicable. |
| 12535 | (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS) |
| 12536 | (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace |
| 12537 | these CPP macros with the m4 macros new defined by... |
| 12538 | (AT_CHECK_PUSHDEFS): this, i.e.: |
| 12539 | (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS) |
| 12540 | (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS) |
| 12541 | New macros. |
| 12542 | (AT_CHECK_POPDEFS): Undefine them. |
| 12543 | (AT_CHECK_CALC_LALR1_CC): New. |
| 12544 | Use it for the first lalr1.cc test. |
| 12545 | |
| 12546 | 2003-02-04 Akim Demaille <akim@epita.fr> |
| 12547 | |
| 12548 | * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on |
| 12549 | Location as is defined. |
| 12550 | |
| 12551 | 2003-02-04 Akim Demaille <akim@epita.fr> |
| 12552 | |
| 12553 | * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon |
| 12554 | name_ being defined. |
| 12555 | |
| 12556 | 2003-02-03 Paul Eggert <eggert@twinsun.com> |
| 12557 | |
| 12558 | * src/gram.h (start_symbol): Remove unused decl. |
| 12559 | |
| 12560 | Use more-consistent naming conventions for local vars. |
| 12561 | |
| 12562 | * src/derives.c (derives_compute): Change type of local var from |
| 12563 | int to rule_number. |
| 12564 | * src/gram.c (grammar_rules_partial_print): Likewise. |

| 12569 | local var from r to rp. |
| 12570 | * src/nullable.c (nullable_compute): Likewise. |
| 12571 | |
| 12572 | * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var. |
| 12573 | |
| 12574 | * src/gram.h (symbol_number_as_item_number): Use sym, not s, |
| 12575 | for symbol or symbol_number var. |
| 12576 | * src/reader.c (grammar_start_symbol_set): Likewise. |
| 12577 | * src/reader.h (grammar_start_symbol_set, grammar_symbol_append): |
| 12578 | Likewise. |
| 12579 | * src/state.c (transitions_to): Likewise. |
| 12580 | * src/state.h: Likewise. |
| 12581 | * src/tables.c (symbol_number_to_vector_number): Likewise. |
| 12582 | |

| 12603 | get_layoutalgorithm_str, get_decision_str, get_orientation_str, |
| 12604 | get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str, |
| 12605 | get_view_str, get_linestyle_str, get_arrowstyle_str): Rename |
| 12606 | param to have same name as that of enum, so that we don't use |
| 12607 | "s" to stand for a non-state. |
| 12608 | |
| 12609 | 2003-02-02 Akim Demaille <akim@epita.fr> |
| 12610 | |
| 12611 | * src/scan-skel.l: Scan more than one inert character per yylex |
| 12612 | invocation. |
| 12613 | |
| 12614 | 2003-02-01 Paul Eggert <eggert@twinsun.com> |
| 12615 | |
| 12616 | Version 1.875a. |
| 12617 | |
| 12618 | * po/LINGUAS: Add ms. |
| 12619 | |
| 12620 | 2003-01-30 Akim Demaille <akim@epita.fr> |
| 12621 | |
| 12622 | * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck. |
| 12623 | |
| 12624 | 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 12625 | |
| 12626 | * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead |
| 12627 | of $1. |
| 12628 | |
| 12629 | Changes in response to error report by S. Eken: GLR mode does not |
| 12630 | handle negative $ indices or $ indices in embedded rules correctly. |
| 12631 | See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>. |
| 12632 | |
| 12633 | * data/glr.c (b4_rhs_value): Change to use YYFILL macro. |
| 12634 | (b4_rhs_location): Ditto. |
| 12635 | (yyfill): New function to copy from stack tree into array |
| 12636 | incrementally. |
| 12637 | (yyuserAction): Modify to allow incremental move of semantic values |
| 12638 | to rhs array when in GLR mode. |
| 12639 | Define YYFILL to use in user-defined actions to fill semantic array |
| 12640 | as needed. |
| 12641 | Remove dummy use of yystack, as there is now a guaranteed use. |
| 12642 | (yydoAction): Modify to allow incremental move of semantic values |
| 12643 | to rhs array when in GLR mode. |
| 12644 | (yyresolveAction): Ditto. |
| 12645 | (yyglrShiftDefer): Update comment. |
| 12646 | (yyresolveStates): Use X == NULL for pointers, not !X. |
| 12647 | (yyglrReduce): Ditto. |
| 12648 | (yydoAction): Ditto |
| 12649 | |
| 12650 | * tests/glr-regr1.at: Rename to ... |
| 12651 | * tests/glr-regression.at: Add new regression test for the problems |
| 12652 | described above (adapted from S. Eken). |
| 12653 | Update copyright notice. |
| 12654 | * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at. |
| 12655 | * tests/Makefile.am: Ditto. |
| 12656 | |
| 12657 | 2003-01-28 Paul Eggert <eggert@twinsun.com> |
| 12658 | |
| 12659 | * data/lalr1.cc: Do not use @output_header_name@ unless |
| 12660 | b4_defines_flag is set. This fixes two bugs reported by |
| 12661 | Tim Van Holder in |
| 12662 | <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html> |
| 12663 | and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>. |
| 12664 | |
| 12665 | 2003-01-21 Paul Eggert <eggert@twinsun.com> |
| 12666 | |
| 12667 | * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that |
| 12668 | we don't need to worry about yyerrlab1 being reported as an |
| 12669 | "unused label" by non-GCC C compilers. The downside is that if |
| 12670 | locations are used then a couple of statements are duplicated each |
| 12671 | time YYERROR is invoked, but the upside is that the warnings |
| 12672 | should vanish. |
| 12673 | (yyerrlab1): Move code to YERROR. |
| 12674 | (yyerrlab2): Remove. Change uses back to yyerrlab1. |
| 12675 | This reverts some of the 2002-12-27 change. |
| 12676 | |
| 12677 | 2003-01-17 Paul Eggert <eggert@twinsun.com> |
| 12678 | |
| 12679 | * src/output.c (symbol_printers_output): Fix typo that led |
| 12680 | to core dump. Problem reported by Antonio Rus in |
| 12681 | <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>. |

| 12685 | Robert Anisko <anisko_r@lrde.epita.fr> |
| 12686 | |
| 12687 | * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop |
| 12688 | when the stacks contain one element, as the loop would otherwise |
| 12689 | free the last state, and then use the top state (the one we just |
| 12690 | popped). This means that the initial elements will not be freed |
| 12691 | explicitly, as is the case in yacc.c; it is not a problem, as |
| 12692 | these elements have fake values. |
| 12693 | |
| 12694 | 2003-01-11 Paul Eggert <eggert@twinsun.com> |
| 12695 | |
| 12696 | * NEWS: %expect-violations are now just warnings, reverting |
| 12697 | to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2 |
| 12698 | bootstrapping problem reported by Matthias Klose; see |
| 12699 | <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>. |
| 12700 | * src/conflicts.c (conflicts_print): Likewise. |
| 12701 | * tests/conflicts.at (%expect not enough, %expect too much, |
| 12702 | %expect with reduce conflicts): Likewise. |
| 12703 | * doc/bison.texinfo (Expect Decl): Document this. Also mention |
| 12704 | that the warning is enabled if the number of conflicts changes |
| 12705 | (not necessarily increases). |
| 12706 | |
| 12707 | * src/getargs.c (version): Update copyright year. |
| 12708 | |
| 12709 | 2003-01-09 Akim Demaille <akim@epita.fr> |
| 12710 | |
| 12711 | * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@. |
| 12712 | |
| 12713 | 2003-01-08 Paul Eggert <eggert@twinsun.com> |
| 12714 | |
| 12715 | * Makefile.maint (WGETFLAGS): |
| 12716 | New macro, containing "-C off" to disable proxy caches. |
| 12717 | All uses of $(WGET) changed to $(WGET) $(WGETFLAGS). |
| 12718 | (rel-check): Use $(WGET) instead of wget. |
| 12719 | |
| 12720 | 2003-01-06 Paul Eggert <eggert@twinsun.com> |
| 12721 | |
| 12722 | * doc/bison.texinfo (Generalized LR Parsing): Add a reference to |
| 12723 | the GLR paper of Scott, Johnstone and Hussain. |
| 12724 | |
| 12725 | 2003-01-04 Paul Eggert <eggert@twinsun.com> |
| 12726 | |
| 12727 | * configure.ac (AC_ARG_ENABLE): Add --disable-yacc. |
| 12728 | (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST. |
| 12729 | * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@. |
| 12730 | (EXTRA_LIBRARIES): New var, for liby.a. |
| 12731 | * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@. |
| 12732 | (EXTRA_SCRIPTS): New var, for yacc. |
| 12733 | |
| 12734 | * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined, |
| 12735 | since GNU C++ (as of 3.2.1) does not allow attributes on labels. |
| 12736 | Problem reported by Nelson H. F. Beebe. |
| 12737 | |
| 12738 | 2003-01-03 Paul Eggert <eggert@twinsun.com> |
| 12739 | |
| 12740 | * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to |
| 12741 | (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5 |
| 12742 | when compiling Bison 1.875's `bitset bset = obstack_alloc |
| 12743 | (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe. |
| 12744 | |
| 12745 | * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition. |
| 12746 | ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not |
| 12747 | grow to a huge size with typical invocation. |
| 12748 | |
| 12749 | * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined): |
| 12750 | Use the pattern recommended by Autoconf 2.57, except also protect |
| 12751 | against double-definition. |
| 12752 | * src/system.h: Likewise. |
| 12753 | Portability issues reported by Nelson H. F. Beebe. |
| 12754 | |
| 12755 | * data/glr.c (yybool): Renamed from bool, to avoid collisions in C. |
| 12756 | All uses changed. Provide a definition in both C and C++. |
| 12757 | (yytrue, yyfalse): Define even if defined (__cplusplus). |
| 12758 | |
| 12759 | * lib/bitset_stats.c (bitset_stats_list): Remove unused var. |
| 12760 | Reported by Nelson H. F. Beebe. |
| 12761 | |
| 12762 | * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno. |
| 12763 | |
| 12764 | 2003-01-02 Paul Eggert <eggert@twinsun.com> |
| 12765 | |
| 12766 | * data/yacc.c (yyerrlab1): Append `;' after attribute, to |
| 12767 | pacify the buggy "smart preprocessor" in MacOS 10.2.3. |
| 12768 | Bug reported by Nelson H. F. Beebe. |
| 12769 | |
| 12770 | 2003-01-01 Paul Eggert <eggert@twinsun.com> |
| 12771 | |
| 12772 | * Version 1.875. |
| 12773 | |
| 12774 | 2002-12-30 Paul Eggert <eggert@twinsun.com> |
| 12775 | |
| 12776 | * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","): |
| 12777 | Moved here from... |
| 12778 | (<INITIAL>","): Here. This causes stray "," to be treated |
| 12779 | more uniformly. |
| 12780 | |
| 12781 | * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the |
| 12782 | last brace in braced code when not in Yacc mode, for compatibility |
| 12783 | with Bison 1.35. This resurrects the 2001-12-15 patch to |
| 12784 | src/reader.c. |
| 12785 | |
| 12786 | * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias |
| 12787 | yystype. This follows up the 2002-12-24 YYSTYPE bug fix. |
| 12788 | |
| 12789 | 2002-12-28 Paul Eggert <eggert@twinsun.com> |
| 12790 | |
| 12791 | * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be |
| 12792 | that of SYM's type. This fixes Debian bug 168069, reported by |
| 12793 | Thomas Olsson. |
| 12794 | |
| 12795 | 2002-12-28 Paul Eggert <eggert@twinsun.com> |
| 12796 | |
| 12797 | Version 1.75f. |
| 12798 | |
| 12799 | Switch back to the Yacc style of conflict reports, undoing some |
| 12800 | of the 2002-07-30 change. |
| 12801 | * doc/bison.texinfo (Understanding): Use Yacc style for |
| 12802 | conflict reports. Also, use new way of locating rules. |
| 12803 | * src/conflicts.c (conflict_report): |
| 12804 | Renamed from conflict_report_yacc, removing the old |
| 12805 | 'conflict_report'. Translate the entire conflict report at once, |
| 12806 | so that we don't assume that "," has the same interpretation in |
| 12807 | all languages. |
| 12808 | (conflicts_output): Use Yacc-style conflict report for each state, |
| 12809 | instead of our more-complicated style. |
| 12810 | (conflicts_print): Use Yacc-style conflict report, except print |
| 12811 | the input file name when not emulating Yacc. |
| 12812 | * tests/conflicts.at (Unresolved SR Conflicts, Defaulted |
| 12813 | Conflicted Reduction, %expect not enough, %expect too much, |
| 12814 | %expect with reduce conflicts): Switch to Yacc-style conflict reports. |
| 12815 | * tests/existing.at (GNU Cim Grammar): Likewise. |
| 12816 | * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise. |
| 12817 | |
| 12818 | * src/complain.c (warn_at, warn, complain_at, complain, fatal_at, |
| 12819 | fatal): Don't invoke fflush; it's not needed and it might even be |
| 12820 | harmful for stdout, as stdout might not be open. |
| 12821 | * src/reduce.c (reduce_print): Likewise. |
| 12822 | |
| 12823 | 2002-12-27 Paul Eggert <eggert@twinsun.com> |
| 12824 | |
| 12825 | Fix a bug where error locations were not being recorded correctly. |
| 12826 | This problem was originally reported by Paul Hilfinger in |
| 12827 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>. |
| 12828 | |
| 12829 | * data/yacc.c (yyparse): New local var yylerrsp, to record the |
| 12830 | top of the location stack's error locations. |
| 12831 | (yyerrlab): Set it. When discarding a token, push its location |
| 12832 | onto yylerrsp so that we don't lose track of the error's end. |
| 12833 | (yyerrlab1): Now is only the target of YYERROR, so that we can |
| 12834 | properly record the location of the action that failed. For GCC |
| 12835 | 2.93 and later, insert an __attribute__ ((__unused__)) to avoid |
| 12836 | GCC warning about yyerrlab1 being unused if YYERROR is unused. |
| 12837 | (yyerrlab2): New label, which yyerrlab now falls through to. |
| 12838 | Compute the error's location by applying YYLLOC_DEFAULT to |
| 12839 | the locations of all the symbols that went into the error. |
| 12840 | * doc/bison.texinfo (Location Default Action): Mention that |
| 12841 | YYLLOC_DEFAULT is also invoked for syntax errors. |
| 12842 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): |
| 12843 | Error locations include the locations of all the tokens that were |
| 12844 | discarded, not just the last token. |
| 12845 | |
| 12846 | 2002-12-26 Paul Eggert <eggert@twinsun.com> |
| 12847 | |
| 12848 | * src/files.c: Include quote.h. |
| 12849 | (compute_output_file_names): Warn if we detect conflicting |
| 12850 | outputs to the same file. This should catch the misunderstanding |
| 12851 | exemplified by Debian Bug 165349, reported by Bruce Stephens.. |
| 12852 | |
| 12853 | * src/conflicts.c (conflicts_print): If the user specifies |
| 12854 | "%expect N", report an error if there are any reduce/reduce |
| 12855 | conflicts. This is what the manual says should happen. |
| 12856 | This fixes Debian bug 130890, reported by Anthony DeRobertis. |
| 12857 | * tests/conflicts.at (%expect with reduce conflicts): New test. |
| 12858 | |
| 12859 | Don't use m4_include on relative file names, as it doesn't work as |
| 12860 | desired if there happens to be a file with that name under ".". |
| 12861 | |
| 12862 | * m4sugar/version.m4: Remove; it was included but it wasn't used. |
| 12863 | * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4. |
| 12864 | * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4. |
| 12865 | * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4. |
| 12866 | * src/output.c (output_skeleton): Use full path names when |
| 12867 | specifying a file to include; don't rely on include path, as |
| 12868 | it's unreliable when the working file contains a file with |
| 12869 | that name. |
| 12870 | |
| 12871 | 2002-12-25 Paul Eggert <eggert@twinsun.com> |
| 12872 | |
| 12873 | Remove obsolete references to bison.simple and bison.hairy. |
| 12874 | Problem mentioned by Aubin Mahe in |
| 12875 | <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>. |
| 12876 | * data/glr.c: Comment fix. |
| 12877 | * doc/bison.1: Remove references. Also, mention "yacc". |
| 12878 | |
| 12879 | * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL |
| 12880 | with -g option. |
| 12881 | |
| 12882 | * src/parse-gram.y (declaration): Use enum "report_states" rather |
| 12883 | than its numeric value 1. |
| 12884 | |
| 12885 | * src/scan-skel.l ("@output ".*\n): Close any old yyout before |
| 12886 | opening a new one. This fixes Debian bug 165349, reported by |
| 12887 | Bruce Stephens. |
| 12888 | |
| 12889 | 2002-12-24 Paul Eggert <eggert@twinsun.com> |
| 12890 | |
| 12891 | Version 1.75e. |
| 12892 | |
| 12893 | * Makefile.maint (cvs-update): Don't assume that the shell |
| 12894 | supports $(...), as Solaris sh doesn't. |
| 12895 | |
| 12896 | * src/parse-gram.y (lloc_default): Remove test for empty |
| 12897 | nonterminals at the end, since it didn't change the result. |
| 12898 | |
| 12899 | 2002-12-24 Paul Eggert <eggert@twinsun.com> |
| 12900 | |
| 12901 | If the user does not define YYSTYPE as a macro, Bison now declares it |
| 12902 | using typedef instead of defining it as a macro. POSIX requires this. |
| 12903 | For consistency, YYLTYPE is also declared instead of defined. |
| 12904 | |
| 12905 | %union directives can now have a tag before the `{', e.g., the |
| 12906 | directive `%union foo {...}' now generates the C code |
| 12907 | `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility. |
| 12908 | The default union tag is `YYSTYPE', for compatibility with Solaris 9 |
| 12909 | Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE' |
| 12910 | instead of `yyltype'. |
| 12911 | |
| 12912 | `yystype' and `yyltype' are now obsolescent macros instead of being |
| 12913 | typedefs or tags; they are no longer documented and will be |
| 12914 | withdrawn in a future release. |
| 12915 | |
| 12916 | * data/glr.c (b4_location_type): Remove. |
| 12917 | (YYSTYPE): Renamed from yystype. |
| 12918 | (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef. |
| 12919 | (struct YYLTYPE): Renamed from struct yyltype. |
| 12920 | (YYLTYPE): Renamed from yyltype. |
| 12921 | (yyltype, yystype): New (and obsolescent) macros, |
| 12922 | for backward compatibility. |
| 12923 | * data/yacc.c: Likewise. |
| 12924 | |
| 12925 | * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user |
| 12926 | does not specify a union tag. This is for compatibility with |
| 12927 | Solaris 9 yacc. |
| 12928 | |
| 12929 | * src/parse-gram.y (add_param): 2nd arg is now char * not char |
| 12930 | const *, since it is now modified by stripping surrounding { }. |
| 12931 | (current_braced_code): Remove. |
| 12932 | (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION, |
| 12933 | PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include |
| 12934 | trailing " {...}". Now of type <chars>. |
| 12935 | (grammar_declaration): Adjust to bundled tokens. |
| 12936 | (code_content): Remove; stripping is now done by add_param. |
| 12937 | (print_token_value): Print contents of bundled tokens. |
| 12938 | (token_name): New function. |
| 12939 | |
| 12940 | * src/reader.h (braced_code, current_braced_code): Remove. |
| 12941 | (token_name): New decl. |
| 12942 | |
| 12943 | * src/scan-gram.l (handle_dollar, handle_at): Now takes int |
| 12944 | token_type, not braced_code code_kind. All uses changed. |
| 12945 | (SC_PRE_CODE): New state, for scanning after a keyword that |
| 12946 | has (or usually has) an immediately-following braced code. |
| 12947 | (token_type): New local var, to keep track of which token type |
| 12948 | to return when scanning braced code. |
| 12949 | (<INITIAL>"%destructor", <INITIAL>"%lex-param", |
| 12950 | <INITIAL>"%parse-param", <INITIAL>"%printer", |
| 12951 | <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE |
| 12952 | instead of returning a token type immediately. |
| 12953 | (<INITIAL>"{"): Set token type. |
| 12954 | (<SC_BRACED_CODE>"}"): Use it. |
| 12955 | (handle_action_dollar, handle_action_at): Now returns bool |
| 12956 | indicating success. Fail if ! current_rule; this prevents a core dump. |
| 12957 | (handle_symbol_code_dollar, handle_symbol_code_at): |
| 12958 | Remove; merge body into caller. |
| 12959 | (handle_dollar, handle_at): Complain in invalid contexts. |
| 12960 | |
| 12961 | * NEWS, doc/bison.texinfo: Document the above. |
| 12962 | * NEWS: Fix years and program names in copyright notice. |

| 12964 | 2002-12-17 Paul Eggert <eggert@twinsun.com> |
| 12965 | |
| 12966 | * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error |
| 12967 | Reporting, Table of Symbols): Omit mentions of %lex-param and |
| 12968 | %parse-param from the documentation for now. |
| 12969 | |
| 12970 | 2002-12-15 Paul Eggert <eggert@twinsun.com> |
| 12971 | |
| 12972 | Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke |
| 12973 | GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no |
| 12974 | lookahead symbol, and which sets yychar in parser actions) and it |
| 12975 | disagreed with the Bison documentation. Bug |
| 12976 | reported by Andrew Walrond. |
| 12977 | |
| 12978 | * data/yacc.c (YYTRANSLATE): Don't check for negative argument, |
| 12979 | as the caller now does that. |
| 12980 | (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken. |
| 12981 | (YYEMPTY): Parenthesize right hand side, since others use it. |
| 12982 | (yyparse): Don't assume that our generated code is the only code |
| 12983 | that sets yychar. |
| 12984 | |
| 12985 | 2002-12-13 Paul Eggert <eggert@twinsun.com> |
| 12986 | |
| 12987 | Version 1.75d. |
| 12988 | |
| 12989 | POSIX requires a "yacc" command. |
| 12990 | * src/Makefile.am (bin_SCRIPTS): New macro, for yacc. |
| 12991 | (MOSTLYCLEANFILES): Add yacc. |
| 12992 | (yacc): New rule. |
| 12993 | * doc/bison.texinfo (Invocation, Bison Options): Mention yacc |
| 12994 | as an alias for bison y. |
| 12995 | |
| 12996 | * po/LINGUAS: Add da. |
| 12997 | |
| 12998 | * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around |
| 12999 | problem with latest <getopt.h>. |
| 13000 | (HACK_FOR___GNU_LIBRARY___PROTOTYPE): New macro. |
| 13001 | |
| 13002 | * doc/fdl.texi: Upgrade to 1.2. |

| 13004 | lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c, |
| 13005 | lib/obstack.h, lib/strnlen.c, lib/unlocked-io.h: Sync with |
| 13006 | gnulib. |
| 13007 | * config/install-sh: Sync with autotools. |
| 13008 | |
| 13009 | Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in |
| 13010 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>. |
| 13011 | * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless |
| 13012 | locations are requested. |
| 13013 | (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless |
| 13014 | locations are requested. |
| 13015 | |
| 13016 | 2002-12-12 Paul Eggert <eggert@twinsun.com> |
| 13017 | |
| 13018 | Remove unportable casts and storage allocation tricks. |
| 13019 | While we're at it, remove almost all casts, since they |
| 13020 | usually aren't needed and are a sign of trouble. |
| 13021 | |
| 13022 | * configure.ac (AC_CHECK_TYPES): Check for uintptr_t. |
| 13023 | |
| 13024 | * src/derives.c (derives_compute): Do not subtract NTOKENS from |
| 13025 | the pointer DSET returned by malloc; this isn't portable. |
| 13026 | Instead, always use DSET[i - NTOKENS] rather than DSET[i]. |
| 13027 | Similarly for DERIVES. |
| 13028 | * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP. |
| 13029 | * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE. |
| 13030 | * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap |
| 13031 | |
| 13032 | * src/derives.c (derives_compute): Do not bother invoking |
| 13033 | int_of_rule_number, since rule numbers are integers. |
| 13034 | |
| 13035 | * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N) |
| 13036 | rather than XMALLOC (char, N). |
| 13037 | |
| 13038 | * src/files.c (filename_split): Rewrite to avoid cast. |
| 13039 | |
| 13040 | * src/gram.h (symbol_number_as_item_number, |
| 13041 | item_number_as_symbol_number, rule_number_as_item_number, |
| 13042 | item_number_as_rule_number): |
| 13043 | Now inline functions rather than macros, to avoid casts. |
| 13044 | * src/state.h (state_number_as_int): Likewise. |
| 13045 | * src/tables.c (state_number_to_vector_number, |
| 13046 | symbol_number_to_vector_number): Likewise. |
| 13047 | |
| 13048 | * src/gram.h (int_of_rule_number): Remove; no longer used. |
| 13049 | |
| 13050 | * src/lalr.c (add_lookback_edge): Use malloc rather than calloc, |
| 13051 | since the resulting storage is always stored into. |
| 13052 | |
| 13053 | * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place |
| 13054 | where it's needed. |
| 13055 | |
| 13056 | * src/muscle_tab.c (muscle_m4_output): |
| 13057 | Now inline. Return bool, not int. |
| 13058 | * src/state.c (state_compare): Likewise. |
| 13059 | * src/symtab.c (symbol_check_defined, |
| 13060 | symbol_check_alias_consistency, symbol_pack, symbol_translation, |
| 13061 | hash_compare_symbol, hash_symbol): |
| 13062 | Likewise. |
| 13063 | * src/uniqstr.c (uniqstr_print): Likewise. |
| 13064 | * src/muscle_tab.c (muscle_m4_output_processor): |
| 13065 | New function, to avoid casts. |
| 13066 | * src/state.c (state_comparator, stage_hasher): Likewise. |
| 13067 | * src/symtab.c (symbol_check_defined_processor, |
| 13068 | symbol_check_alias_consistency_processor, symbol_pack_processor, |
| 13069 | symbol_translation_processor, hash_symbol_comparator, |
| 13070 | hash_symbol_hasher): Likewise. |
| 13071 | * src/uniqstr.c (uniqstr_print_processor): Likewise. |
| 13072 | * src/muscle_tab.c (muscles_m4_output): |
| 13073 | Use new functions instead of casting old functions unportably. |
| 13074 | * src/state.c (state_hash_new): Likewise. |
| 13075 | * src/symtab.c (symbols_new, symbols_do, symbols_check_defined, |
| 13076 | symbols_token_translations_init): |
| 13077 | Likewise. |
| 13078 | * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise. |
| 13079 | |
| 13080 | * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local |
| 13081 | var instead of casting to long, to avoid casts. |
| 13082 | (prepare_states): Use MALLOC rather than alloca, so that we don't |
| 13083 | have to worry about alloca. |
| 13084 | * src/state.c (state_hash_lookup): Likewise. |
| 13085 | |
| 13086 | * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char |
| 13087 | local var instead of casting to unsigned char, to avoid casts. |
| 13088 | |
| 13089 | * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC, |
| 13090 | STATE_ALLOC): Remove. |
| 13091 | (transitions_new, errs_new, reductions_new, state_new): Use malloc |
| 13092 | rather than calloc, and use offsetof to avoid allocating slightly |
| 13093 | too much storage. |
| 13094 | (state_new): Initialize all members. |
| 13095 | |
| 13096 | * src/state.c (state_hash): Use unsigned accumulator, not signed. |
| 13097 | |
| 13098 | * src/symtab.c (symbol_free): Remove; unused. |
| 13099 | (symbol_get): Remove cast in lhs of assignment. |
| 13100 | (symbols_do): Now static. Accept generic arguments, not |
| 13101 | hashing-related ones. |
| 13102 | |
| 13103 | * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast. |
| 13104 | (symbol_processor): Remove. |
| 13105 | (symbols_do): Remove decl; now static. |
| 13106 | |
| 13107 | * src/system.h (alloca): Remove; decl no longer needed. |
| 13108 | (<stddef.h>): Include, for offsetof. |
| 13109 | (<inttypes.>, <stdint.h>): Include if available. |
| 13110 | (uintptr_t): New type, if system lacks it. |
| 13111 | (CALLOC, MALLOC, REALLOC): New macros. |
| 13112 | All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these |
| 13113 | new macros. |
| 13114 | |
| 13115 | * src/tables.c (table_size): Now int, to pacify GCC. |
| 13116 | (table_grow, table_ninf_remap): Use signed table size. |
| 13117 | (save_row): Don't bother initializing locals when not needed. |
| 13118 | (default_goto, goto_actions, pack_vector): Remove unnecessary casts. |
| 13119 | * src/uniqstr.c (hash_compare_uniqstr): Likewise. |
| 13120 | |
| 13121 | * src/vcg.h: Correct misspellings. |
| 13122 | |
| 13123 | * src/vcg_defaults.h (G_CMAX): Now INT_MAX. |
| 13124 | |
| 13125 | |
| 13126 | * src/getargs.c (getargs): Don't assume EOF == -1. |
| 13127 | |
| 13128 | 2002-12-09 Paul Eggert <eggert@twinsun.com> |
| 13129 | |
| 13130 | Change identifier spellings to avoid collisions with names |
| 13131 | that are reserved by POSIX. |
| 13132 | |
| 13133 | Don't use names ending in _t, since POSIX reserves them. |
| 13134 | For consistency, remove _e and _s endings -- they're weren't |
| 13135 | needed to remove ambiguity. All uses changed. |
| 13136 | * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in |
| 13137 | turn was just renamed from struniq_t. |
| 13138 | * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor, |
| 13139 | which in turn was just renamed from struniq_processor_t. |
| 13140 | (hash_compare_uniqstr): Renamed from hash_compare_struniq, which |
| 13141 | in turn was renamed from hash_compare_struniq_t. |

| 13209 | Rename value_t -> value. |
| 13210 | * tests/input.at (Torturing the Scanner): Rename value_t -> value, |
| 13211 | value_t_as_yystype -> value_as_yystype. |
| 13212 | |
| 13213 | Don't include <errno.h> in the mainstream code, since it |
| 13214 | reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'. |
| 13215 | * lib/get-errno.c, lib/get-errno.h: New files. |
| 13216 | * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h, |
| 13217 | get-errno.c. |
| 13218 | * src/files.c (xfopen, xfclose): Use get_errno instead of errno. |
| 13219 | * src/output.c (output_skeleton): Likewise. |
| 13220 | * src/scan-gram.l (<INITIAL>{int}): Use set_errno and get_errno |
| 13221 | instead of errno. |

| 13226 | (TAB_EXT): Renamed from EXT_TAB. |
| 13227 | (OUTPUT_EXT): Renamed from EXT_OUTPUT. |
| 13228 | |
| 13229 | Avoid str[a-z]*, since <string.h> reserves that name space. |
| 13230 | Change all instances of "struniq" in names to "uniqstr", and |
| 13231 | likewise for "STRUNIQ" and "UNIQSTR". |
| 13232 | * src/uniqstr.c: Renamed from src/struniq.c. |
| 13233 | * src/uniqstr.h: Renamed from src/struniq.h. |
| 13234 | * src/Makefile.am (bison_SOURCES): Adjust to these renamings. |

| 13260 | |
| 13261 | |
| 13262 | Fix misspelling in names. |
| 13263 | * src/vcg.h (enum_alignment_e): Renamed from enum_alignement_e. |
| 13264 | * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from |
| 13265 | G_NODE_ALIGNEMENT. |

| 13268 | * lib/timevar.c (timevar_report): Renamed from time_report, |
| 13269 | for consistency with other names. |
| 13270 | * lib/timevar.h (timevar_report): New decl. |
| 13271 | * src/system.h (time_report): Remove; decl is now in lib/timevar.h. |
| 13272 | |
| 13273 | |
| 13274 | Sort include-file uses. |
| 13275 | |
| 13276 | Reorder all include files under src to be in the order "system.h". |
| 13277 | then the ../lib include files in angle brackets (alphabetized), |
| 13278 | then the . include files in double-quotes (alphabetized). Fix |
| 13279 | dependency breakages encountered in this process, as follows: |
| 13280 | * src/closure.h, src/derives.h, src/state.h: Include "gram.h". |
| 13281 | * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff. |
| 13282 | * src/state.h: Include "symtab.h". |

| 13284 | 2002-12-08 Paul Eggert <eggert@twinsun.com> |
| 13285 | |
| 13286 | * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__, |
| 13287 | since this causes problems when __file__ contains character |
| 13288 | sequences like "@" that are treated specially by src/scan-skel.l. |
| 13289 | Instead, just use the file's basename. This fixes the bug |
| 13290 | reported by Martin Mokrejs in |
| 13291 | <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>. |

| 13294 | |
| 13295 | Add support for rules that do not have trailing semicolons, as |
| 13296 | POSIX requires. Improve the quality of locations in Bison |
| 13297 | diagnostics. |
| 13298 | |
| 13299 | * src/location.c: Include <quotearg.h>. |
| 13300 | (empty_location): Now const. |
| 13301 | (location_print): New function. Follow the recommendation of the |
| 13302 | GNU Coding Standards for locations that span file boundaries. |
| 13303 | * src/location.h: Do not include <quotearg.h>; no longer needed. |
| 13304 | (boundary): New type. |
| 13305 | (location_t): Use it. This allows locations to span file boundaries. |
| 13306 | All member uses changed: file -> start.file or end.file (as needed), |
| 13307 | first_line -> start.line, first_column -> start.column, |
| 13308 | last_line -> end.line, last_column -> end.column. |
| 13309 | (equal_boundaries): New function. |
| 13310 | (LOCATION_RESET, LOCATION_STEP): Remove. |
| 13311 | (LOCATION_PRINT): Remove. All callers changed to use location_print. |
| 13312 | (empty_location): Now const. |
| 13313 | (location_print): New decl. |
| 13314 | * src/parse-gram.y (lloc_default): New function, which handles |
| 13315 | empty locations more accurately. |
| 13316 | (YYLLOC_DEFAULT): Use it. |
| 13317 | (%token COLON): Remove. |
| 13318 | (%token ID_COLON): New token. |
| 13319 | (rules): Use it. |
| 13320 | (declarations, rules): Remove trailing semicolon. |
| 13321 | (declaration, rules_or_grammar_declaration): |
| 13322 | Allow empty (";") declaration. |
| 13323 | (symbol_def): Remove empty actions; no longer needed. |
| 13324 | (rules_or_grammar_declaration): Remove trailing semicolon. |
| 13325 | (semi_colon.opt): Remove. |
| 13326 | * src/reader.h: Include location.h. |
| 13327 | (scanner_cursor): New decl. |
| 13328 | * src/reduce.c (nonterminals_reduce): Use warn_at rather than |
| 13329 | rolling our own. |
| 13330 | * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead |
| 13331 | of *loc. |
| 13332 | (STEP): Remove. No longer needed, now that adjust_location does |
| 13333 | the work. All uses removed. |
| 13334 | (scanner_cursor): New var. |
| 13335 | (adjust_location): Renamed from extend_location. It now sets |
| 13336 | *loc and adjusts the scanner cursor. All uses changed. |
| 13337 | Don't bother testing for CR. |
| 13338 | (handle_syncline): Remove location arg; now updates scanner cursor. |
| 13339 | All callers changed. |
| 13340 | (unexpected_end_of_file): Now accepts start boundary of token or |
| 13341 | comment, not location. All callers changed. Update scanner cursor, |
| 13342 | not the location. |
| 13343 | (SC_AFTER_IDENTIFIER): New state. |
| 13344 | (context_state): Renamed from c_context. All uses changed. |
| 13345 | (id_loc, code_start, token_start): New local vars. |
| 13346 | (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all |
| 13347 | processing of Yacc white space and equivalents here. |
| 13348 | (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER |
| 13349 | instead of returning ID immediately, since we need to search for |
| 13350 | a subsequent colon. |
| 13351 | (<INITIAL>"'", "\""): Save token_start. |
| 13352 | (<INITIAL>"%{", "{", "%%"): Save code_start. |
| 13353 | (<SC_AFTER_IDENTIFIER>): New state, looking for a colon. |
| 13354 | (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>): |
| 13355 | BEGIN context_state at end, not INITIAL. |
| 13356 | (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'", |
| 13357 | <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>): |
| 13358 | Return correct token start. |
| 13359 | (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when |
| 13360 | the start of a character, string or multiline comment is found. |
| 13361 | * tests/conflicts.at (S/R in initial, Defaulted Conflicted |
| 13362 | Reduction): Adjust reported locations to match the more-precise |
| 13363 | results now expected. |
| 13364 | * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise. |
| 13365 | * tests/reduce.at (Useless Rules, Reduced Automaton, |
| 13366 | Underivable Rules): Likewise. |
| 13367 | * tests/regression.at (Invalid inputs): No longer `expecting ";" |
| 13368 | or "|"' now that so many other tokens are allowed by the new grammar. |
| 13369 | |
| 13370 | * src/complain.h (current_file): Remove duplicate decl; |
| 13371 | current_file is now owned by files.h. |
| 13372 | * src/complain.c, src/scan-gram.l: Include files.h. |
| 13373 | |
| 13374 | 2002-12-06 Paul Eggert <eggert@twinsun.com> |
| 13375 | |
| 13376 | * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule] |
| 13377 | promotes to int; it might be unsigned int. |
| 13378 | * data/yacc.c (yy_reduce_print): Likewise. |
| 13379 | |
| 13380 | * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should |
| 13381 | be #defined in the prologue, not in the Bison declarations. |
| 13382 | This fixes Debian Bug 102878, reported by Shaul Karl. |
| 13383 | |
| 13384 | 2002-12-02 Paul Eggert <eggert@twinsun.com> |
| 13385 | |
| 13386 | * configure.ac (AC_REPLACE_FUNCS): Add strtoul. |
| 13387 | * lib/strtoul.c: New file, from gnulib. |
| 13388 | This fixes a porting bug reported by Peter Klein in |
| 13389 | <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>. |
| 13390 | |
| 13391 | 2002-11-30 Paul Eggert <eggert@twinsun.com> |
| 13392 | |
| 13393 | * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue, |
| 13394 | and put only a forward declaration in the prologue. This is for |
| 13395 | consistency with the other scanner helper functions. |
| 13396 | |
| 13397 | Type clashes now generate warnings, not errors, since it |
| 13398 | appears that POSIX may allow some grammars with type clashes. |
| 13399 | * src/reader.c (grammar_current_rule_check): Warn about |
| 13400 | type clashes instead of complaining. |
| 13401 | * tests/input.at (Type Clashes): Expect warnings, not complaints. |
| 13402 | |
| 13403 | Add Yacc library, since POSIX requires it. |
| 13404 | * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu. |
| 13405 | * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros. |
| 13406 | * lib/main.c, lib/yyerror.c: New files. |
| 13407 | |
| 13408 | gram_error can be static; it need not be extern. |
| 13409 | * src/reader.h (gram_error): Remove decl. |
| 13410 | * src/parse-gram.y (gram_error): Now static. Add static decl. |
| 13411 | (print_token_value): Omit parameter names from forward decl, |
| 13412 | for consistency. |
| 13413 | |
| 13414 | 2002-11-29 Paul Eggert <eggert@twinsun.com> |
| 13415 | |
| 13416 | * doc/bison.texinfo: Emphasize that yylex and yyerror must |
| 13417 | be declared before being used. E.g., one should typically |
| 13418 | declare them in the prologue. Use GNU coding style in examples. |
| 13419 | Put "const" consistently after the type it modifies. Mention |
| 13420 | that C99 supports "inline". Mention that yyerror traditionally |
| 13421 | returns "int". |
| 13422 | |
| 13423 | %parse-param and %lex-param now take just one argument, the |
| 13424 | declaration; the argument name is deduced from the declaration. |
| 13425 | |
| 13426 | * doc/bison.texinfo (Parser Function, Pure Calling, Error |
| 13427 | Reporting, Table of Symbols): Document this. |
| 13428 | * src/parse-gram.y (add_param): New function. |
| 13429 | (COMMA): Remove. |
| 13430 | (declaration): Implement new rule for %parse-param and %lex-param. |
| 13431 | * src/scan-gram.l: "," now elicits a warning, rather than being |
| 13432 | a token; this is more compatible with byacc. |
| 13433 | * tests/calc.at (Simple LALR Calculator): Adopt new convention. |
| 13434 | |
| 13435 | 2002-11-27 Paul Eggert <eggert@twinsun.com> |
| 13436 | |
| 13437 | Rename identifiers to avoid real and potential collisions. |
| 13438 | |
| 13439 | * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput, |
| 13440 | to avoid collision with lex macro described by Bruce Lilly in |
| 13441 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>. |
| 13442 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise. |
| 13443 | * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value. |
| 13444 | * src/parse-gram.y (print_token_value): Renamed from yyprint. |
| 13445 | All uses changed. |
| 13446 | (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed. |
| 13447 | The name "yycontrol" violates the name space rules, and this stuff |
| 13448 | wasn't being used anyway. |
| 13449 | (input): Remove action; this stuff wasn't being used. |
| 13450 | (gram_error): Rename local variable yylloc -> loc. |
| 13451 | * src/reader.h (struct gram_control_s, gram_control_t): Remove. |
| 13452 | (YY_DECL): Don't use "yy" at start of local variables. |
| 13453 | All uses changed, e.g., yylloc -> loc. |
| 13454 | * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed. |
| 13455 | (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed. |
| 13456 | (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed. |
| 13457 | (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed. |
| 13458 | |
| 13459 | * src/parse-gram.y (gram_error): loc is now const *. |
| 13460 | * src/reader.h (gram_error): Likewise. |
| 13461 | |
| 13462 | 2002-11-24 Paul Eggert <eggert@twinsun.com> |
| 13463 | |
| 13464 | Version 1.75c. |
| 13465 | |
| 13466 | * tests/actions.at (Actions after errors): Use an output format |
| 13467 | more similar to that of the Printers and Destructors test. |
| 13468 | Test the position of the ';' token too. |
| 13469 | (Printers and Destructors): Likewise. |
| 13470 | (Printers and Destructors: %glr-parser): Remove for now, to avoid |
| 13471 | unnecessarily alarming people when the test fails. |
| 13472 | |
| 13473 | * data/yacc.c (yyerrlab1): Move this label down, so that the |
| 13474 | parser does not discard the lookahead token if the user code |
| 13475 | invokes YYERROR. This change is required for POSIX conformance. |
| 13476 | |
| 13477 | * lib/error.c: Sync with gnulib. |
| 13478 | |
| 13479 | 2002-11-22 Paul Eggert <eggert@twinsun.com> |
| 13480 | |

| 13489 | 2002-11-20 Paul Eggert <eggert@twinsun.com> |
| 13490 | |
| 13491 | Avoid use of <assert.h>, as the GNU Coding Standards hint that one |
| 13492 | should use `if (! x) abort ();' rather than `assert (x);', and |
| 13493 | anyway it's one less thing to worry about configuring. |
| 13494 | |
| 13495 | * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>. |
| 13496 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise, |
| 13497 | and replace all instances of assert with abort. |
| 13498 | * tests/calc.at (_AT_DATA_CALC_Y): Likewise. |

| 13523 | |
| 13524 | * src/system.h (verify): New macro. |
| 13525 | * src/getargs.c (trace_argmatch, report_argmatch): Use verify |

| 13527 | * src/tables.c (tables_generate): Likewise. |
| 13528 | |
| 13529 | * src/struniq.c (struniq_assert): Now returns void, and aborts |
| 13530 | if the assertion is false. |
| 13531 | (struniq_assert_p): Remove. |
| 13532 | * src/struniq.h: Likewise. |
| 13533 | |
| 13534 | 2002-11-18 Paul Eggert <eggert@twinsun.com> |
| 13535 | |
| 13536 | * data/glr.c (yygetLRActions): Replace `yyindex' with |
| 13537 | `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch. |
| 13538 | This fixes the regression with Sun ONE Studio 7 cc that I reported in |
| 13539 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>. |
| 13540 | |
| 13541 | 2002-11-18 Akim Demaille <akim@epita.fr> |
| 13542 | |
| 13543 | * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a |
| 13544 | space. |
| 13545 | From Tim Van Holder. |
| 13546 | |
| 13547 | 2002-11-17 Paul Eggert <eggert@twinsun.com> |
| 13548 | |
| 13549 | Pacify Sun ONE Studio 7 lint. Also, rename "ParseError" |
| 13550 | to "SyntaxError" for consistency with my 2002-11-15 change. |
| 13551 | |
| 13552 | * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do |
| 13553 | not define to {}, since this breaks the common use of `YYDPRINTF |
| 13554 | ((...));' if a single statement is desired (e.g. before `else'). |
| 13555 | Work around GCC warnings by surrounding corresponding calls with |
| 13556 | {} if needed. |
| 13557 | (yyhasResolvedValue): Remove unused function. |
| 13558 | (yymergeOptionSets, yyresolvStack): Use `continue;' for empty |
| 13559 | loop body. |
| 13560 | (yyreportSyntaxError): Renamed from yyreportParseError. |
| 13561 | (yyrecoverSyntaxError): Renamed from yyrecoverParseError. |
| 13562 | All uses changed. |
| 13563 | * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of |
| 13564 | extern when possible. Remove unused initializations. |
| 13565 | |
| 13566 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 13567 | |
| 13568 | Augment the similarity between GLR and LALR traces. |
| 13569 | |
| 13570 | * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print) |
| 13571 | (YY_REDUCE_PRINT): New. |
| 13572 | (yyparse): Use them. |
| 13573 | * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for |
| 13574 | YYDPRINT here. |
| 13575 | (yyglrReduce, yyrecoverParseError, yyparse): Don't report the |
| 13576 | state reached after the reduction/recovery, since... |
| 13577 | (yyparse, yyprocessOneStack): Report the state we are entering in. |
| 13578 | |
| 13579 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 13580 | |
| 13581 | * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types): |
| 13582 | Add support for --trace=skeleton. |
| 13583 | * src/scan-skel.l: %option debug. |
| 13584 | Scan strings of non-@ or \n instead of character by character. |
| 13585 | (scan_skel): Handle trace_skeleton. |
| 13586 | (QPUTS): New. |
| 13587 | (@output_parser_name@, @output_header_name@): ``Restore'' their |
| 13588 | support (used to be M4 macros). |
| 13589 | * data/yacc.c: Quote larger chunks, a la glr.c. |
| 13590 | * data/lalr1.cc: Likewise. |
| 13591 | The header guards are no longer available, so use some other |
| 13592 | string than `YYLSP_NEEDED'. |
| 13593 | |
| 13594 | 2002-11-16 Akim Demaille <akim@epita.fr> |
| 13595 | |
| 13596 | Make the ``Printers and Destructors'' test more verbose, taking |
| 13597 | `yacc.c''s behavior as (possibly wrong) reference. |
| 13598 | |
| 13599 | * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf |
| 13600 | instead of fprint on stdout. |
| 13601 | Set and report the last_line of the symbols. |
| 13602 | Consistently display values and locations. |
| 13603 | |
| 13604 | 2002-11-16 Paul Eggert <eggert@twinsun.com> |
| 13605 | |
| 13606 | * data/yacc.c: Avoid over-quoting of __line__ and __file__. |
| 13607 | |
| 13608 | 2002-11-15 Paul Eggert <eggert@twinsun.com> |
| 13609 | |
| 13610 | * tests/actions.at (Actions after errors): New test case. |
| 13611 | |
| 13612 | * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo, |
| 13613 | src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h, |
| 13614 | tests/action.at, tests/calc.at, tests/conflicts.at, |
| 13615 | tests/cxx-type.at, tests/regression.at: |
| 13616 | "parse error" -> "syntax error" for POSIX compatibility. |
| 13617 | "parsing stack overflow..." -> "parser stack overflow" so |
| 13618 | that code matches Bison documentation. |
| 13619 | |
| 13620 | 2002-11-15 Akim Demaille <akim@epita.fr> |
| 13621 | |
| 13622 | * src/parse-gram.y (declaration): Have %parse-param and %lex-param |
| 13623 | take two BRACED_CODE, not two string_content. |
| 13624 | Free the scanner's obstack when we are done. |
| 13625 | (code_content): New. |
| 13626 | * tests/calc.at: Adjust. |
| 13627 | * doc/bison.texinfo: Adjust. |
| 13628 | Also, make sure to include the `,' for these declarations. |
| 13629 | |
| 13630 | 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be> |
| 13631 | |
| 13632 | * m4/prereq.m4: Removed the commented jm_PREREQ_HASH |
| 13633 | definition; avoids potential autoreconf problems. |
| 13634 | |
| 13635 | 2002-11-15 Akim Demaille <akim@epita.fr> |
| 13636 | |
| 13637 | Always check the value returned by yyparse. |
| 13638 | |
| 13639 | * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value |
| 13640 | returned by yyparse. |
| 13641 | (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument. |
| 13642 | Adjust calls. |
| 13643 | * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value |
| 13644 | returned by yyparse. |
| 13645 | |
| 13646 | 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 13647 | |
| 13648 | * data/glr.c (yyFail): Always set yyerrflag. Corrects regression |
| 13649 | on input.at test. |
| 13650 | |
| 13651 | 2002-11-14 Paul Eggert <eggert@twinsun.com> |
| 13652 | |
| 13653 | * src/output.c (output_skeleton): Call xfopen instead of |
| 13654 | duplicating xfopen's body. |
| 13655 | |
| 13656 | Fix bugs reported by Nelson H. F. Beebe in |
| 13657 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>. |
| 13658 | |
| 13659 | * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that |
| 13660 | "$CC -E foo.h" is allowed, as this doesn't work with the Portland |
| 13661 | Group compiler. Instead, use "$CC -E bar.c". Include the .h |
| 13662 | file twice in the grammar, as an extra check. |
| 13663 | |
| 13664 | * tests/input.at (Torturing the Scanner): Surround the |
| 13665 | backslash-newline tests with "#if 0", to make it less likely that |
| 13666 | we'll run into compiler bugs. Bring back solitary \ inside |
| 13667 | comment, but add a closing comment to work around HP C bug. Don't |
| 13668 | test backslash-newline in C character constant. |
| 13669 | |
| 13670 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 13671 | |
| 13672 | * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit |
| 13673 | status of the compiler. |
| 13674 | Calling `exit 1' is no longer needed. |
| 13675 | Reported by Nelson H. F. Beebe. |
| 13676 | |
| 13677 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 13678 | |
| 13679 | * tests/atlocal.in (CPPFLAGS): We have config.h. |
| 13680 | * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR): |
| 13681 | New. |
| 13682 | * tests/actions.at, tests/calc.at, tests/conflicts.at, |
| 13683 | * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at, |
| 13684 | * tests/regression.at, tests/torture.at: Use them for all the |
| 13685 | grammars that are to be compiled. |
| 13686 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as... |
| 13687 | * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this. |
| 13688 | * doc/bison.texinfo (GLR Parsers): Document `inline'. |

| 13690 | 2002-11-14 Akim Demaille <akim@epita.fr> |
| 13691 | |
| 13692 | * doc/bison.texinfo: Various formatting changes (alignments in |
| 13693 | samples, additional @group/@end group, GCS in samples. |
| 13694 | Use @deffn instead of simple @table to define the directives, |
| 13695 | macros, variables etc. |
| 13696 | |
| 13697 | 2002-11-13 Paul Eggert <eggert@twinsun.com> |
| 13698 | |
| 13699 | Fix some bugs reported by Albert Chin-A-Young in |
| 13700 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>. |
| 13701 | |
| 13702 | * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c |
| 13703 | -o c"; the HP C compiler chatters during compilation. |
| 13704 | Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c". |
| 13705 | * tests/headers.at (export YYLTYPE): Likewise. |
| 13706 | |
| 13707 | * tests/input.at (Torturing the Scanner): Remove lines containing |
| 13708 | solitary backslashes, as they tickle a bug in the HP C compiler. |
| 13709 | |
| 13710 | * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid // |
| 13711 | comments, since they're not portable. Use GNU coding style. |
| 13712 | |
| 13713 | 2002-11-13 Akim Demaille <akim@epita.fr> |
| 13714 | |
| 13715 | * data/yacc.c: Leave bigger chunks of quoted text. |
| 13716 | (YYDSYMPRINTF): New. |
| 13717 | Use it to report symbol activities. |
| 13718 | * data/glr.c (YYDSYMPRINTF): New. |
| 13719 | Use it. |
| 13720 | |
| 13721 | 2002-11-12 Paul Eggert <eggert@twinsun.com> |
| 13722 | |
| 13723 | Version 1.75b. |
| 13724 | |
| 13725 | * data/glr.c (yydoAction): Return YYRESULTTAG, not int. |
| 13726 | (yyglrReduce): Return yyok, not 0. |
| 13727 | This should avoid the enumerated-type warnings reported |
| 13728 | by Nelson H. F. Beebe in |
| 13729 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>. |

| 13734 | to avoid shadowing warnings by GCC. |
| 13735 | |
| 13736 | * data/glr.c (inline): Remove #define. It's the user's |
| 13737 | responsibility to #define it away, just like 'const'. |
| 13738 | This fixes one of the bugs reported by Nelson H. F. Beebe in |
| 13739 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>. |
| 13740 | |
| 13741 | * Makefile.maint (po-check): Scan .l and .y files instead of the |
| 13742 | .c and the .h files that they generate. This fixes the bug |
| 13743 | reported by Tim Van Holder in: |
| 13744 | <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html> |
| 13745 | Look for N_ as well as for _. Try to avoid matching #define for |
| 13746 | N_ and _. |
| 13747 | * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c, |
| 13748 | src/system.h. Add src/parse-gram.y, src/scan-gram.l. |
| 13749 | * src/scan-gram.l: Revamp regular expressions so that " and ' |
| 13750 | do not confuse xgettext. |
| 13751 | |
| 13752 | * src/struniq.h (struniq_new): Do not declare the return type |
| 13753 | to be 'const'; this violates the C standard. |
| 13754 | * src/struniq.c (struniq_new): Likewise. |
| 13755 | |
| 13756 | 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com> |
| 13757 | |
| 13758 | * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the |
| 13759 | duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq |
| 13760 | linker. |
| 13761 | |
| 13762 | 2002-11-12 Akim Demaille <akim@epita.fr> |

| 13782 | |
| 13783 | * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New. |

| 13786 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 13787 | |
| 13788 | * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton |
| 13789 | defines it. |
| 13790 | * data/glr.c (yystos): New. |
| 13791 | (b4_yysymprint_generate, b4_yydestruct_generate): Invoke. |

| 13801 | * tests/cations.at (Printers and Destructors): Use Bison directives |

| 13808 | * data/yacc.c: Rename yychar1 as yytoken, as in glr.c. |
| 13809 | Don't work on yychar (i.e., do set it to YYEMPTY, don't match |
| 13810 | it against YYEMPTY and so forth), work on yytoken (i.e., set |
| 13811 | it to YYEMPTY etc.). |
| 13812 | (yydestruct): Replace with a b4_yydestruct_generate invocation. |
| 13813 | (b4_symbol_actions): Remove. |
| 13814 | * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands |
| 13815 | for 0, end-of-input. |
| 13816 | |
| 13817 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 13818 | |

| 13821 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 13822 | |
| 13823 | * src/tables.c (tables_generate): Use free for pointers that |

| 13884 | file names. |
| 13885 | Don't free the input file name. |
| 13886 | |
| 13887 | 2002-11-12 Akim Demaille <akim@epita.fr> |
| 13888 | |
| 13889 | * src/symtab.c (symbol_free): Remove dead deactivated code: |
| 13890 | type_name are properly removed. |
| 13891 | Don't use XFREE to free items that cannot be NULL. |
| 13892 | * src/struniq.h, src/struniq.c: New. |
| 13893 | * src/main.c (main): Initialize/free struniqs. |
| 13894 | * src/parse-gram.y (%union): Add astruniq member. |
| 13895 | (yyprint): Adjust. |
| 13896 | * src/scan-gram.l (<{tag}>): Return a struniq. |
| 13897 | Free the obstack bit that used to store it. |
| 13898 | * src/symtab.h (symbol_t): The 'type_name' member is a struniq. |

| 13900 | 2002-11-11 Paul Eggert <eggert@twinsun.com> |
| 13901 | |
| 13902 | Revamp to fix many (but not all) of the C- and M4-related quoting |
| 13903 | problems. Among other things, this fixes the Bison bug reported |
| 13904 | by Jan Hubicka when processing the Bash grammar; see: |
| 13905 | <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html> |
| 13906 | |
| 13907 | Use new @ escapes consistently. Represent brackets with @{ and @} |
| 13908 | rather than @<:@ and @:>@, since this works a bit better with dumb |
| 13909 | editors like vi. Represent @ with @@, since @ is now consistently |
| 13910 | an escape. Use @oline@ and @ofile@ rather than __oline__ and |
| 13911 | __ofile__, to avoid unexpected expansions. Similarly, use @output |
| 13912 | rather than #output. |
| 13913 | |
| 13914 | * data/c.m4 (b4_copyright): Omit file name from comment, since |
| 13915 | the file name could contain "*/". |
| 13916 | (b4_synclines_flag): Don't quote the 2nd argument; it should already |
| 13917 | be quoted. All uses changed. |
| 13918 | |
| 13919 | * data/glr.c: Use new @ escapes consistently. |
| 13920 | (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name, |
| 13921 | b4_output_header_suffix, b4_output_header_name, b4_header_guard): |
| 13922 | Remove, since they couldn't handle arbitrary characters in file |
| 13923 | names. |
| 13924 | * data/lalr1.cc: Likewise. |
| 13925 | * data/yacc.c: Likewise. |
| 13926 | |
| 13927 | * src/files.c (output_infix): Remove; all uses removed. |
| 13928 | * src/files.h: Likewise. |
| 13929 | |
| 13930 | * data/glr.c: Remove use of "#ifdef b4_header_guard", since it |
| 13931 | mishandled funny characters in file names, and anyway it isn't |
| 13932 | needed any more. |
| 13933 | * data/yacc.c: Likewise. |
| 13934 | * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard. |
| 13935 | |
| 13936 | * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would. |
| 13937 | * data/yacc.c: Likewise. |
| 13938 | |
| 13939 | * src/muscle_tab.c: Include quotearg.h, since we need to quote C |
| 13940 | strings now. |
| 13941 | (muscle_init): Quote filename as a C string. |
| 13942 | * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused. |
| 13943 | (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros. |
| 13944 | * src/output.c (escaped_file_name_output): New function. |
| 13945 | (prepare_symbols): Quote tokens for M4. |
| 13946 | (prepare): Don't insert output_infix, output_prefix, |
| 13947 | output_parser_name, output_header_name; this is now down by scan-skel. |
| 13948 | Insert skeleton as a C string. |
| 13949 | |
| 13950 | * src/output.c (user_actions_output, symbol_destructors_output, |
| 13951 | symbol_printers_output): Quote filenames for C and M4. |
| 13952 | * src/reader.c (prologue_augment, epilogue_set): Likewise. |
| 13953 | |
| 13954 | * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash |
| 13955 | escapes other than \\ and \'; this simplifies the code. |
| 13956 | (<SC_STRING>): Likewise, for \\ and \". |
| 13957 | (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE, |
| 13958 | SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too. |
| 13959 | Use new escapes @{ and @} for [ and ]. |
| 13960 | |
| 13961 | * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing |
| 13962 | them with auto vars. |
| 13963 | Switch to new escape scheme, where @ is the escape character uniformly. |
| 13964 | Abort if a stray escape character is found. Avoid unbounded input |
| 13965 | buffer when parsing non-escaped text. |
| 13966 | |
| 13967 | * tests/input.at (Torturing the Scanner): Add tests that @oline@, |
| 13968 | __oline__, #output, $@, and @{ do not have unintended meanings. |
| 13969 | |
| 13970 | 2002-11-09 Paul Eggert <eggert@twinsun.com> |
| 13971 | |
| 13972 | Fix the test failure due to GCC warnings described in |
| 13973 | <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>. |
| 13974 | * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which |
| 13975 | evaluate to 0 if it's impossible for NINF to be in the respective |
| 13976 | table. |
| 13977 | (yygetLRActions, yyrecoverParseError): Use them. |
| 13978 | |
| 13979 | * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were |
| 13980 | counted in the token inserted at end of file. Now takes |
| 13981 | location_t *, not location_t, so that the location can be |
| 13982 | adjusted. All uses changed. |
| 13983 | |
| 13984 | * tests/regression.at (Invalid inputs): Adjust wording in |
| 13985 | diagnostic to match the new behavior. |
| 13986 | |
| 13987 | * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR, |
| 13988 | AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR, |
| 13989 | AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x)) |
| 13990 | abort ();'. This reduces the runtime of the "Many lookaheads" |
| 13991 | test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running |
| 13992 | GCC 3.2. |
| 13993 | |
| 13994 | 2002-11-07 Paul Eggert <eggert@twinsun.com> |
| 13995 | |
| 13996 | * src/parse-gram.y (CHARACTER): Remove unused token. |
| 13997 | All uses removed. |
| 13998 | |
| 13999 | * src/scan-gram.l: Remove stack option. We no longer use the |
| 14000 | stack, since the stack was never deeper than 1; instead, use the |
| 14001 | new auto var c_context to record the stacked value. |
| 14002 | |
| 14003 | Remove nounput option. At an unexpected end of file, we now unput |
| 14004 | the minimal input necessary to end cleanly; this simplifies the |
| 14005 | code. |
| 14006 | |
| 14007 | Avoid unbounded token sizes where this is easy. |
| 14008 | |
| 14009 | (unexpected_end_of_file): New function. |
| 14010 | Use it to systematize the error message on unexpected EOF. |
| 14011 | (last-string): Now auto, not static. |
| 14012 | (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. |
| 14013 | (scanner_last_string_free): Remove; not used. |
| 14014 | (percent_percent_count): Move decl to just before use. |
| 14015 | (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, |
| 14016 | not the (never otherwised-used) CHARACTER. |
| 14017 | |
| 14018 | 2002-11-07 Akim Demaille <akim@epita.fr> |
| 14019 | |
| 14020 | Let yyerror always receive the msg as last argument, so that |
| 14021 | yyerror can be variadic. |
| 14022 | |
| 14023 | * data/yacc.c (b4_yyerror_args): New. |
| 14024 | Use it when calling yyerror. |

| 14031 | 2002-11-06 Akim Demaille <akim@epita.fr> |

| 14033 | #line should have quoted strings. |
| 14034 | Ideally, this should be done by m4_quotearg. |
| 14035 | |
| 14036 | * src/scan-skel.l: Include quotearg.h. |
| 14037 | Quote __ofile__. |
| 14038 | * src/output.c (symbol_printers_output) |
| 14039 | (symbol_destructors_output): Quote the file name. |

| 14052 | * data/glr.c, data/yacc.c, data/lalr1.cc: Use it. |
| 14053 | * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline. |
| 14054 | * src/output.c (user_actions_output): Likewise. |
| 14055 | (prepare): Define 'b4_synclines_flag'. |
| 14056 | * src/muscle_tab.c (muscle_init): Don't define b4_linef. |
| 14057 | |
| 14058 | 2002-11-06 Akim Demaille <akim@epita.fr> |
| 14059 | |
| 14060 | * src/main.c (main): Free `infile'. |
| 14061 | * src/scan-gram.l (handle_syncline): New. |
| 14062 | Recognize `#line'. |
| 14063 | * src/output.c (user_actions_output, symbol_destructors_output) |
| 14064 | (symbol_printers_output): Use the location's file name, not |
| 14065 | infile. |
| 14066 | * src/reader.c (prologue_augment, epilogue_set): Likewise. |

| 14068 | 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 14069 | |
| 14070 | * src/tables.c (matching_state): Don't allow states to match if |
| 14071 | either has GLR conflict entries. |
| 14072 | |
| 14073 | 2002-11-05 Paul Eggert <eggert@twinsun.com> |
| 14074 | |
| 14075 | * src/scan-gram.l: Use more accurate diagnostics, e.g. |
| 14076 | "integer out of range" rather than "invalid value". |
| 14077 | * tests/input.at (Invalid $n, Invalid @n): Change expected wording |
| 14078 | accordingly. |
| 14079 | |
| 14080 | Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires. |
| 14081 | Also, remove one static variable in the scanner. |
| 14082 | |
| 14083 | * src/scan-gram.l (braces_level): Now auto, not static. |
| 14084 | Initialize to zero if the compiler is being picky. |
| 14085 | (INITIAL): Clear braces_level instead of incrementing it. |
| 14086 | (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code, |
| 14087 | as POSIX 1003.1-2001 requires. |
| 14088 | * src/system.h (IF_LINT): New macro, taken from coreutils. |
| 14089 | * configure.ac: Define "lint" if --enable-gcc-warnings. |
| 14090 | |
| 14091 | 2002-11-05 Akim Demaille <akim@epita.fr> |
| 14092 | |
| 14093 | * src/scan-gram.l: When it starts with `%', complain about the |
| 14094 | whole directive, not just that `invalid character: %'. |
| 14095 | |
| 14096 | 2002-11-04 Akim Demaille <akim@epita.fr> |
| 14097 | |

| 14109 | |
| 14110 | 2002-11-04 Akim Demaille <akim@epita.fr> |
| 14111 | |
| 14112 | * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid |
| 14113 | clashes. |
| 14114 | * src/scan-gram.l: Use [\'] instead of ['] to pacify |
| 14115 | font-lock-mode. |
| 14116 | Use complain_at. |
| 14117 | Use quote, not quote_n since LOCATION_PRINT no longer uses the |
| 14118 | slot 0. |
| 14119 | |
| 14120 | 2002-11-03 Paul Eggert <eggert@twinsun.com> |
| 14121 | |
| 14122 | * src/reader.c (get_merge_function, grammar_current_rule_check): |

| 14164 | * tests/calc.at: Change all the AT_CHECK_CALC_LALR and |

| 14168 | |
| 14169 | 2002-11-03 Paul Eggert <eggert@twinsun.com> |
| 14170 | |
| 14171 | * src/scan-gram.l: Revamp to fix POSIX incompatibilities, |
| 14172 | to count columns correctly, and to check for invalid inputs. |
| 14173 | |
| 14174 | Use mbsnwidth to count columns correctly. Account for tabs, too. |
| 14175 | Include mbswidth.h. |
| 14176 | (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS. |
| 14177 | (extend_location): New function. |

| 14188 | (SC_LINE_COMMENT, SC_YACC_COMMENT): New states. |
| 14189 | (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.; |
| 14190 | all uses changed. |
| 14191 | (tag, splice): New EREs. Do not allow NUL or newline in tags. |
| 14192 | Use {splice} wherever C allows backslash-newline. |
| 14193 | YY_STEP after space, newline, vertical-tab. |
| 14194 | ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT). |
| 14195 | |
| 14196 | (letter, id): Don't assume ASCII; e.g., spell out a-z. |

| 14199 | overflow. |
| 14200 | |

| 14202 | |
| 14203 | (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00 |
| 14204 | as well as \000. Check for UCHAR_MAX, not 255. |

| 14206 | Check for overflow here. |
| 14207 | Allow \? and UCNs, for compatibility with C. |
| 14208 | |
| 14209 | (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision |

| 14235 | * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two |
| 14236 | bug in trigraph handling. |
| 14237 | |
| 14238 | * src/output.c (prepare_symbols): When printing token names, |
| 14239 | escape "[" as "@<:@" and likewise for "]". |
| 14240 | |
| 14241 | * src/system.h (errno): Remove declaration, as we are now |
| 14242 | assuming C89 or better, and C89 guarantees errno. |
| 14243 | |
| 14244 | 2002-10-30 Paul Eggert <eggert@twinsun.com> |
| 14245 | |
| 14246 | * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write): |
| 14247 | Check for close failures. |
| 14248 | * src/files.h (xfclose): Return void, not int, since it always |
| 14249 | returned zero. |
| 14250 | * src/files.c (xfclose): Likewise. Report I/O error if ferror |
| 14251 | indicates one. |
| 14252 | * src/output.c (output_skeleton): Use xfclose rather than fclose |
| 14253 | and ferror. xfclose now checks ferror. |
| 14254 | |
| 14255 | * data/glr.c (YYLEFTMOST_STATE): Remove. |
| 14256 | (yyreportTree): Use a stack-based leftmost state. This avoids |
| 14257 | our continuing battles with bogus warnings about initializers. |
| 14258 | |
| 14259 | 2002-10-30 Akim Demaille <akim@epita.fr> |
| 14260 | |
| 14261 | * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only |
| 14262 | #if. |
| 14263 | |
| 14264 | 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU> |
| 14265 | |
| 14266 | * tests/glr-regr1.at: New test for reported regressions. |
| 14267 | * tests/testsuite.at: Add glr-regr1.at test. |
| 14268 | * tests/Makefile.am: Add glr-regr1.at test. |
| 14269 | |
| 14270 | 2002-10-24 Paul Eggert <eggert@twinsun.com> |
| 14271 | |
| 14272 | Version 1.75a. |
| 14273 | |
| 14274 | * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration. |
| 14275 | * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since |
| 14276 | we use malloc. Don't assume 'A' through 'Z' are contiguous. |
| 14277 | Don't assume strdup exists; POSIX says its an XSI extension. |
| 14278 | Check for buffer overflow on input. |
| 14279 | |
| 14280 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 14281 | |
| 14282 | * src/output.c (output_skeleton): Don't disable M4sugar comments |
| 14283 | too soon: it results in comments being expanded. |
| 14284 | * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the |
| 14285 | first output. |
| 14286 | |
| 14287 | 2002-10-24 Akim Demaille <akim@epita.fr> |
| 14288 | |
| 14289 | * data/yacc.c (m4_int_type): New. |
| 14290 | * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed |
| 14291 | char' as only yacc.c wants K&R portability. |
| 14292 | * data/glr.c (yysigned_char): Remove. |
| 14293 | * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name. |
| 14294 | Reported by Quoc Peyrot. |
| 14295 | |
| 14296 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 14297 | |
| 14298 | * src/main.c (main): With --trace=time, report times even if a |
| 14299 | non-fatal error occurs. Formerly, the times were reported in some |
| 14300 | such cases but not in others. |
| 14301 | * src/reader.c (reader): Just return if a complaint has been issued, |
| 14302 | instead of exiting, so that 'main' can report times. |
| 14303 | |
| 14304 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 14305 | |
| 14306 | * src/system.h: Include sys/types. |
| 14307 | Reported by Bert Deknuydt. |
| 14308 | |
| 14309 | 2002-10-23 Paul Eggert <eggert@twinsun.com> |
| 14310 | |
| 14311 | * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX. |
| 14312 | Suggested by Art Haas. |
| 14313 | |
| 14314 | 2002-10-22 Paul Eggert <eggert@twinsun.com> |
| 14315 | |
| 14316 | * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit |
| 14317 | decl; not needed any more. |
| 14318 | * src/main.c (main): Use return to exit, undoing yesterday's change. |
| 14319 | The last OS that we could find where this wouldn't work is |
| 14320 | SunOS 3.5, and that's too old to worry about now. |
| 14321 | |
| 14322 | * data/glr.c (struct yyltype): Define members even when not |
| 14323 | doing locations. This is more consistent with yacc.c, and it |
| 14324 | works around the following bug reports: |
| 14325 | http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html |
| 14326 | http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html |
| 14327 | |
| 14328 | * doc/bison.texinfo: Minor spelling and typographical fixes. Use |
| 14329 | @acronym consistently. Standardize on "Yacc" instead of "YACC", |
| 14330 | "Algol" instead of "ALGOL". Give a bit more history about BNF. |
| 14331 | |
| 14332 | 2002-10-22 Akim Demaille <akim@epita.fr> |
| 14333 | |
| 14334 | * data/README: New. |
| 14335 | |
| 14336 | 2002-10-21 Paul Eggert <eggert@twinsun.com> |
| 14337 | |
| 14338 | Be consistent about 'bool'; the old code used an enum in one |
| 14339 | module and an int in another, and this violates the C standard. |
| 14340 | * m4/stdbool.m4: New file, from coreutils 4.5.3. |
| 14341 | * configure.ac (AC_HEADER_STDBOOL): Add. |
| 14342 | * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4. |
| 14343 | * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a) |
| 14344 | * src/symtab.c (hash_compare_symbol_t): Likewise. |
| 14345 | * src/system.h (bool, false, true): Use a definition consistent |
| 14346 | with ../lib/hash.c. All uses changed. |
| 14347 | |
| 14348 | * src/complain.c (warning_issued): Renamed from warn_message_count, |
| 14349 | so that we needn't worry about integer overflow (!). |
| 14350 | Now of type bool. All uses changed. |
| 14351 | (complaint_issued): Renamed from complain_message_count; likewise. |
| 14352 | |
| 14353 | * src/main.c (main): Use exit to exit with failure. |
| 14354 | |
| 14355 | * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS |
| 14356 | rather than 1 and 0. |
| 14357 | * src/main.c (main): Likewise. |
| 14358 | * src/getargs.c (getargs): Likewise. |
| 14359 | * src/reader.c (reader): Likewise. |
| 14360 | |
| 14361 | * src/getarg.c (getargs): Remove duplicate code for |
| 14362 | "Try `bison --help'". |
| 14363 | |
| 14364 | * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2. |
| 14365 | What was that "2" for? |
| 14366 | |
| 14367 | * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)). |
| 14368 | * src/getargs.c (usage): Likewise. |
| 14369 | |
| 14370 | * src/getargs.c (getargs): When there are too few operands, report |
| 14371 | the last one. When there are too many, report the first extra |
| 14372 | one. This is how diffutils does it. |
| 14373 | |
| 14374 | 2002-10-20 Paul Eggert <eggert@twinsun.com> |
| 14375 | |
| 14376 | Remove K&R vestiges. |
| 14377 | * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove. |
| 14378 | * src/complain.c (VA_START): Remove. Assume prototypes. |
| 14379 | (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro. |
| 14380 | (private_strerror, warn_at, warn, complain_at, complain, fatal_at, |
| 14381 | fatal): Assume prototypes. |
| 14382 | * src/complain.h: Assume prototypes. |
| 14383 | * src/system.h (PARAMS): Remove. |
| 14384 | Include <limits.h> unconditionally, since it's guaranteeed even |
| 14385 | for a freestanding C89 compiler. |
| 14386 | (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them. |
| 14387 | * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype. |
| 14388 | |
| 14389 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14390 | |
| 14391 | * src/muscle_tab.c (muscle_grow): Remove trailing debugging code. |
| 14392 | * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New. |
| 14393 | (yyuserAction, yydoAction, yyglrReduce, yyresolveValue) |
| 14394 | (yyresolveStates, yyresolveAction, yyresolveStack) |
| 14395 | (yyprocessOneStack): Use them. |
| 14396 | (yy_reduce_print): New. |
| 14397 | * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param. |
| 14398 | |
| 14399 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14400 | |
| 14401 | * data/c.m4 (b4_c_ansi_args): Recognize functions with no |
| 14402 | arguments and output `void'. |
| 14403 | (b4_c_function): Rename as... |
| 14404 | (b4_c_function_def): this. |
| 14405 | (b4_c_function_decl, b4_c_ansi_function_def) |
| 14406 | (b4_c_ansi_function_decl): New. |
| 14407 | Change the interpretation of the arguments: before `int, foo', now |
| 14408 | `int foo, foo'. |
| 14409 | * data/yacc.c (yyparse): Prototype and define thanks to these. |
| 14410 | Adjust b4_c_function_def uses. |
| 14411 | * data/glr.c (yyparse): Likewise, but ANSI only. |
| 14412 | |
| 14413 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14414 | |
| 14415 | * src/output.c (prepare): Move the definition of `tokens_number', |
| 14416 | `nterms_number', `undef_token_number', `user_token_number_max' |
| 14417 | to... |
| 14418 | (prepare_tokens): Here. |
| 14419 | (prepare_tokens): Rename as... |
| 14420 | (prepare_symbols): this. |
| 14421 | (prepare): Move the definition of `rules_number' to... |
| 14422 | (prepare_rules): here. |
| 14423 | (prepare): Move the definition of `last', `final_state_number', |
| 14424 | `states_number' to... |
| 14425 | (prepare_states): here. |
| 14426 | * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'. |
| 14427 | |
| 14428 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14429 | |
| 14430 | * src/tables.h, src/tables.c, src/output.c: Comment changes. |
| 14431 | |
| 14432 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14433 | |
| 14434 | * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to... |
| 14435 | * data/c.m4: here. |
| 14436 | |
| 14437 | 2002-10-20 Akim Demaille <akim@epita.fr> |
| 14438 | |
| 14439 | * src/output.c (prepare): Use MUSCLE_INSERT_STRING. |
| 14440 | * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as |
| 14441 | `pair'. |
| 14442 | (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth', |
| 14443 | `name' to... |
| 14444 | * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type) |
| 14445 | (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name): |
| 14446 | These. |
| 14447 | |
| 14448 | 2002-10-19 Paul Eggert <eggert@twinsun.com> |
| 14449 | |
| 14450 | Do not create a temporary file, as that involves security and |
| 14451 | cleanup headaches. Instead, use a pair of pipes. |
| 14452 | Derived from a suggestion by Florian Krohm. |
| 14453 | * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files. |
| 14454 | * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove. |
| 14455 | * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove. |
| 14456 | (BISON_PREREQ_SUBPIPE): Add. |
| 14457 | * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c. |
| 14458 | Add subpipe.h, subpipe.c. |
| 14459 | * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4. |
| 14460 | * po/POTFILES.in: Add lib/subpipe.c. |
| 14461 | * src/output.c: Include "subpipe.h". |
| 14462 | (m4_invoke): Remove decl. |
| 14463 | (scan_skel): New decl. |
| 14464 | (output_skeleton): Use pipe rather than temporary file for m4 input. |
| 14465 | Check that m4sugar.m4 is readable, to avoid deadlock. |
| 14466 | Check for pipe I/O error. |
| 14467 | * src/scan-skel.l (readpipe): Remove decl. |
| 14468 | (scan_skel): New function, to be used in place of m4_invoke. |
| 14469 | Read from stream rather than file. |
| 14470 | |
| 14471 | * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to |
| 14472 | float, as this generates a warning on Solaris 8 + GCC 3.2 with |
| 14473 | --enable-gcc-warnings. Instead, divide into 1.0 rather than 1; |
| 14474 | this generates a more-accurate value anyway. |
| 14475 | |
| 14476 | * lib/timevar.c (timervar_accumulate): Rename locals to |
| 14477 | avoid confusion with similarly-named more-global. |
| 14478 | * src/muscle_tab.c (muscle_pair_list_grow): Likewise. |
| 14479 | |
| 14480 | * src/output.c (prepare): Use xstrdup to convert char const * |
| 14481 | to char *, to avoid GCC warning. |
| 14482 | |
| 14483 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 14484 | |
| 14485 | * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS, |
| 14486 | LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS. |
| 14487 | Use them to have `calc.y' ready for %pure-parser. |
| 14488 | * data/yacc.c (YYLEX): Pass a yylex return type to |
| 14489 | b4_c_function_call. |
| 14490 | |
| 14491 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 14492 | |
| 14493 | Prototype support of %lex-param and %parse-param. |
| 14494 | |
| 14495 | * src/parse-gram.y: Add the definition of the %lex-param and |
| 14496 | %parse-param tokens, plus their rules. |
| 14497 | Drop the `_' version of %glr-parser. |
| 14498 | Add the "," token. |
| 14499 | * src/scan-gram.l (INITIAL): Scan them. |
| 14500 | * src/muscle_tab.c: Comment changes. |
| 14501 | (muscle_insert, muscle_find): Rename `pair' as `probe'. |
| 14502 | * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused. |
| 14503 | (muscle_entry_s): The `value' member is no longer const. |
| 14504 | Adjust all dependencies. |
| 14505 | * src/muscle_tab.c (muscle_init): Adjust: use |
| 14506 | MUSCLE_INSERT_STRING. |
| 14507 | Initialize the obstack earlier. |
| 14508 | * src/muscle_tab.h, src/muscle_tab.c (muscle_grow) |
| 14509 | (muscle_pair_list_grow): New. |
| 14510 | * data/c.m4 (b4_c_function_call, b4_c_args): New. |
| 14511 | * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param. |
| 14512 | * tests/calc.at: Use %locations, not --locations. |
| 14513 | (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser. |
| 14514 | |
| 14515 | 2002-10-19 Akim Demaille <akim@epita.fr> |
| 14516 | |
| 14517 | * src/getargs.c (usage): Take status as argument and exit |
| 14518 | accordingly. |
| 14519 | Report the traditional `Try ... --help' message when status != 0. |
| 14520 | (usage, version): Don't take a FILE * as arg, it is pointless. |
| 14521 | (getargs): When there is an incorrect number of arguments, make it |
| 14522 | an error, and report it GNUlically thanks to `usage ()'. |
| 14523 | |
| 14524 | 2002-10-18 Paul Eggert <eggert@twinsun.com> |
| 14525 | |
| 14526 | * data/glr.c (yyreportParseError): Don't assume that sprintf |
| 14527 | yields the length of the printed string, as this is not true |
| 14528 | on SunOS 4.1.4. Reported by Peter Klein. |
| 14529 | |
| 14530 | * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc. |
| 14531 | * tests/conflicts.at (%nonassoc and eof): Likewise. |
| 14532 | Fixes SunOS 4.1.4 test failure reported by Peter Klein. |
| 14533 | |
| 14534 | 2002-10-17 Akim Demaille <akim@epita.fr> |
| 14535 | |
| 14536 | * src/getargs.h (trace_e): Add trace_scan, and trace_parse. |
| 14537 | * src/getargs.c (trace_types, trace_args): Adjust. |
| 14538 | * src/reader.c (grammar_current_rule_prec_set) |
| 14539 | (grammar_current_rule_dprec_set, grammar_current_rule_merge_set): |
| 14540 | Standardize error messages. |
| 14541 | And s/@prec/%prec/! |
| 14542 | (reader): Use trace_flag to enable scanner/parser debugging, |
| 14543 | instead of an adhoc scheme. |
| 14544 | * src/scan-gram.l: Remove trailing debugging code. |
| 14545 | |
| 14546 | 2002-10-16 Paul Eggert <eggert@twinsun.com> |
| 14547 | |
| 14548 | * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as |
| 14549 | MUSCLE_TAB_H. |
| 14550 | |
| 14551 | * NEWS: Officially drop support for building Bison with K&R C, |
| 14552 | since it didn't work anyway and it's not worth worrying about. |
| 14553 | * Makefile.maint (wget_files): Remove ansi2knr.c. |
| 14554 | (ansi2knr.c-url_prefix): Remove. |
| 14555 | * lib/.cvsignore: Remove ansi2knr, ansi2knr.*. |
| 14556 | * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove. |
| 14557 | * src/Makefile.am (AUTOMAKE_OPTIONS): Remove. |
| 14558 | |
| 14559 | 2002-10-15 Paul Eggert <eggert@twinsun.com> |
| 14560 | |
| 14561 | Stop using the "enum_" trick for K&R-style function definitions; |
| 14562 | it confused me, and I was the author! Instead, assume that people |
| 14563 | who want to use K&R C compilers (when using these modules in GCC, |
| 14564 | perhaps?) will run ansi2knr. |
| 14565 | |
| 14566 | * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove. |
| 14567 | All uses of "enum_" changed to "enum ". |
| 14568 | * lib/ebitset.c (enum_ebitset_find_mode): Likewise. |
| 14569 | * lib/lbitset.c (enum_lbitset_find_mode): Likewise. |

| 14658 | Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c", |

| 14672 | true due to limited range of data type" warning from GCC. |
| 14673 | |
| 14674 | * data/c.m4 (b4_token_defines): Protect against double-inclusion |
| 14675 | by wrapping enum yytokentype's definition inside #ifndef |
| 14676 | YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12. |

| 14696 | Let nondeterministic skeletons be usable with deterministic |
| 14697 | tables. |
| 14698 | |
| 14699 | With the patch, GAWK compiled by GCC without -O2 passes its test |
| 14700 | suite using a GLR parser driven by LALR tables. It fails with -O2 |
| 14701 | because `struct stat' gives two different answers on my machine: |
| 14702 | 88 (definition of an auto var) and later 96 (memset on this var). |
| 14703 | Hence the stack is badly corrumpted. The headers inclusion is to |
| 14704 | blame: if I move the awk.h inclusion before GLR's system header |
| 14705 | inclusion, the two struct stat have the same size. |
| 14706 | |
| 14707 | * src/tables.c (pack_table): Always create conflict_table. |
| 14708 | (token_actions): Always create conflict_list. |
| 14709 | * data/glr.c (YYFLAG): Remove, unused. |
| 14710 | |

| 14714 | (O0FLAGS): New. |
| 14715 | (VALGRIND, GXX): New. |
| 14716 | * tests/atlocal.in (CFLAGS): Use O0FLAGS. |
| 14717 | * tests/bison.in: Run $PREBISON a pre-command. |

| 14725 | Tweak some trace messages to match yacc.c's. |

| 14727 | 2002-10-13 Akim Demaille <akim@epita.fr> |

| 14729 | GLR parsers sometimes raise parse errors instead of performing the |
| 14730 | default reduction. |
| 14731 | Reported by Charles-Henry de Boysson. |
| 14732 | |
| 14733 | * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't |
| 14734 | check the length of the traces when %glr. |
| 14735 | (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from |
| 14736 | GLR's traces. |
| 14737 | (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New. |
| 14738 | Test GLR parsers. |
| 14739 | * data/glr.c (YYLEFTMOST_STATE): Fix its value. |
| 14740 | (yyltype): Remove the yy prefix from the member names. |
| 14741 | (yytable): Complete its comment. |
| 14742 | (yygetLRActions): Map error action number from YYTABLE from |
| 14743 | YYTABLE_NINF to 0. |
| 14744 | (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF |
| 14745 | (which was a bug: it should have been YYTABEL_NINF, and yet it was |
| 14746 | not satisfying as we could compare an YYACTION computed from |
| 14747 | YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the |
| 14748 | only value for error actions. |
| 14749 | (yyreportParseError): In verbose parse error messages, don't issue |
| 14750 | `error' in the list of expected tokens. |
| 14751 | * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the |
| 14752 | next action to perform to match glr.c's decoding. |
| 14753 | (yytable): Complete its comment. |

| 14755 | 2002-10-13 Paul Eggert <eggert@twinsun.com> |

| 14757 | Fix problem reported by Henrik Grubbstroem in |
| 14758 | <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>: |
| 14759 | "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected, |
| 14760 | because the Bison parser reads the second action before reducing |
| 14761 | the first one. |
| 14762 | * src/scan-gram.l (rule_length): New static var. |
| 14763 | Use it to keep track of the rule length in the scanner, since |
| 14764 | we can't expect the parser to be in lock-step sync with the scanner. |
| 14765 | (handle_action_dollar, handle_action_at): Use this var. |
| 14766 | * tests/actions.at (Exotic Dollars): Test for the problem. |
| 14767 | |
| 14768 | 2002-10-12 Paul Eggert <eggert@twinsun.com> |
| 14769 | |
| 14770 | * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>. |
| 14771 | * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>. |
| 14772 | Include <sys/time.h> when checking for clock_t and struct tms. |
| 14773 | Use same include order as source. |
| 14774 | This is for the SunOS 4.1.4 porting bug reported by Peter Klein in |
| 14775 | <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>. |
| 14776 | |
| 14777 | * lib/timevar.c: Update copyright date and clarify comments. |
| 14778 | (get_time) [IN_GCC]: Keep the GCC version for reference. |
| 14779 | |
| 14780 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import |
| 14781 | GCC version as of today, then merge Bison's changes. |
| 14782 | Change "GCC" to "Bison" in copyright notice. timevar.def's |
| 14783 | author is Akim, so change that too. |
| 14784 | |
| 14785 | * src/reader.c (grammar_current_rule_check): |
| 14786 | Don't worry about the default action if $$ is untyped. |
| 14787 | Prevents bogus warnings reported by Jim Gifford in |
| 14788 | <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>. |
| 14789 | |
| 14790 | * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE. |
| 14791 | * data/glr.c, data/lalr1.cc, data/yacc.c: |
| 14792 | Output token definitions before the first part of user declarations. |
| 14793 | Fixes compatibility problem reported by Jim Gifford for kbd in |
| 14794 | <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>. |

| 14796 | 2002-10-11 Paul Eggert <eggert@twinsun.com> |
| 14797 | |
| 14798 | * data/yacc.c (yyreport_parse_error): Remove, putting its body into... |
| 14799 | (yyparse): here. This undoes some of the 2002-07-25 change. |
| 14800 | Compatibility problem reported by Ralf S. Engelschall with |

| 14821 | |
| 14822 | * lib/abitset.c (abitset_bytes): Return a size that is aligned |

| 14825 | properly aligned for the whole union. |
| 14826 | * lib/bitsetv.c (bitsetv_alloc): Likewise. |

| 14859 | * lib/lbitset.h: Likewise. |
| 14860 | |
| 14861 | * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types. |
| 14862 | All instances of parameters of type enum bitset_opts are now of |

| 14864 | for enum_bitset_type. |

| 14867 | |
| 14868 | Do not use "struct bitset_struct" to mean different things in |
| 14869 | different modules. Not only is this confusing, it violates |
| 14870 | the C Standard, which requires that structure types in different |
| 14871 | modules must be compatible if one is to be passed to the other. |
| 14872 | * lib/bbitset.h (bitset): Now points to a union, not to a struct. |
| 14873 | All instances of "struct bitset_struct *" replaced with "bitset". |
| 14874 | * lib/bitset.h (struct bitset_struct): Remove, replacing with.... |
| 14875 | (union bitset_union, struct abitset_struct, struct ebitset_struct, |
| 14876 | struct lbitset_struct, struct bitset_stats_struct): New types. |
| 14877 | All uses of struct bitset_struct changed to union bitset_union, |

| 15235 | name locals "index", as it generates unnecessary warnings on some |
| 15236 | hosts that have an "index" function. |
| 15237 | |
| 15238 | * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print, |
| 15239 | bitset_stats_read, bitset_stats_write): Wrap strings in _() if |
| 15240 | they need translation. |

| 15260 | src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c, |

| 15262 | Use src/parse-gram.y instead of src/parse-gram.c, as the gettext |
| 15263 | manual recommends. |
| 15264 | Similarly, use src/scan-gram.l instead of src/scan-gram.c. |
| 15265 | |
| 15266 | * src/complain.c (strerror_r): Remove decl; not needed. |

| 15272 | |
| 15273 | * src/main.c (main): Cast result of bindtextdomain and textdomain |
| 15274 | to void, to avoid a GCC warning when --disable-nls is in effect. |
| 15275 | |
| 15276 | * src/scan-gram.l: Use strings rather than escapes when possible, |
| 15277 | to minimize the number of warnings from xgettext. |
| 15278 | (handle_action_dollar, handle_action_at): Don't use isdigit, |
| 15279 | as it mishandles negative chars and it may not work as expected |
| 15280 | outside the C locale. |
| 15281 | |
| 15282 | * src/symtab.c (symbol_get): Don't cast LHS of an assignment; |
| 15283 | this is a GCC extension and is not portable to other compilers. |
| 15284 | |
| 15285 | * src/system.h (alloca): Use same pattern as ../lib/error.c. |
| 15286 | Do not include <ctype.h>; no longer needed. |

| 15288 | warnings on OpenBSD 3.0). |
| 15289 | |
| 15290 | * tests/cxx-type.at (yylex): Do not pass signed char to isupper; |
| 15291 | it's not portable. |
| 15292 | |

| 15294 | Sun C rejects this. Instead, use 'cc -c input.c -o input.o'. |
| 15295 | |
| 15296 | * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero |
| 15297 | exit status as failure, not just exit status 1. Sun C exits |

| 15322 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 15323 | |
| 15324 | Instead of attaching lookaheads and duplicating the rules being |

| 15328 | `lookaheads_rule' member. |

| 15341 | (initialize_LA): this. |
| 15342 | (lalr_free): Adjust. |
| 15343 | * src/main.c (main): Don't free nullable and derives too early: it |
| 15344 | is used by --verbose. |
| 15345 | * src/print.c, src/print_graph.c, src/tables.c: Adjust. |
| 15346 | |
| 15347 | 2002-08-01 Akim Demaille <akim@epita.fr> |
| 15348 | |

| 15375 | Don't free LA and LArule, main does. |
| 15376 | |
| 15377 | 2002-07-31 Akim Demaille <akim@epita.fr> |

| 15406 | |
| 15407 | * lib/timevar.c, lib/timevar.h, lib/timevar.def: New, |
| 15408 | stolen/adjusted from GCC. |

| 15424 | * src/getargs.c (trace_args, trace_types, trace_argmatch): New. |

| 15427 | Change all the uses of trace_flag to reflect the new flags. |
| 15428 | * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets. |
| 15429 | |

| 15459 | 2002-07-30 Akim Demaille <akim@epita.fr> |

| 15463 | |
| 15464 | * src/LR0.c (save_reductions): Don't make the final state too |
| 15465 | different: save its reduction (accept) instead of having a state |
| 15466 | without any action (no shift or goto, no reduce). |
| 15467 | Note: the final state is now a ``regular'' state, i.e., the |
| 15468 | parsers now contain `reduce 0' as default reduction. |
| 15469 | Nevertheless, since they decide to `accept' when yystate = |
| 15470 | final_state, they still will not reduce rule 0. |
| 15471 | * src/print.c (print_actions, print_reduction): Adjust. |
| 15472 | * src/output.c (action_row): Track reduced rules. |
| 15473 | (token_actions): Report rules never reduced. |

| 15478 | `stage' was accidently included in a previous patch. |
| 15479 | Initiate its autoconfiscation. |
| 15480 | |
| 15481 | * configure.in: Look for malloc.h and sys/times.h. |
| 15482 | * src/main.c (stage): Adjust. |
| 15483 | Report only when trace_flag. |
| 15484 | |

| 15500 | (endtoken, accept): these. |

| 15502 | Set undeftoken's tag to "$undefined" instead of "$undefined.". |
| 15503 | * doc/bison.texinfo (Table of Symbols): Mention $accept and $end. |
| 15504 | Adjust. |
| 15505 | |
| 15506 | 2002-07-29 Akim Demaille <akim@epita.fr> |
| 15507 | |
| 15508 | * src/reduce.c (reduce_grammar): When the language is empty, |
| 15509 | complain about the start symbol, not the axiom. |
| 15510 | Use its location. |
| 15511 | * tests/reduce.at (Empty Language): New. |
| 15512 | |
| 15513 | 2002-07-26 Akim Demaille <akim@epita.fr> |
| 15514 | |
| 15515 | * src/reader.h, src/reader.c (gram_error): ... can't get |

| 15517 | itself. |
| 15518 | * src/output.c (prepare_tokens): Use the real 0th value of |
| 15519 | token_translations instead of `0'. |
| 15520 | * src/parse-gram.y (yyerror): Don't rely on yycontrol being |
| 15521 | visible here. |
| 15522 | * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc |
| 15523 | for the time being: %locations ought to provide it to yyerror. |
| 15524 | |
| 15525 | 2002-07-25 Akim Demaille <akim@epita.fr> |
| 15526 | |
| 15527 | * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1. |

| 17037 | Remove the so called hairy (semantic) parsers. |
| 17038 | |
| 17039 | * src/system.h (EXT_GUARD_C, EXT_STYPE_H): Remove. |
| 17040 | * src/gram.h, src/gram.c (semantic_parser): Remove. |
| 17041 | (rule_t): Remove the guard and guard_line members. |
| 17042 | * src/lex.h (token_t): remove tok_guard. |

| 17047 | (token_definitions_output): Don't output the `T' |
| 17048 | tokens (???). |
| 17049 | (output_skeleton): Don't output the guards. |
| 17050 | * src/files.c, src/files.c (attrsfile): Remove. |
| 17051 | * src/reader.c (symbol_list): Remove the guard and guard_line |

| 17060 | |
| 17061 | * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action) |
| 17062 | (parse_guard): Rename the formal argument `stack_offset' as |
| 17063 | `rule_length', which is more readable. |
| 17064 | Adjust callers. |
| 17065 | (copy_at, copy_dollar): Instead of outputting the hard coded |
| 17066 | values of $$, $n and so forth, output invocation to b4_lhs_value, |
| 17067 | b4_lhs_location, b4_rhs_value, and b4_rhs_location. |
| 17068 | Note: this patch partially drops `semantic-parser' support: it |
| 17069 | always does `rule_length - n', where semantic parsers ought to |
| 17070 | always use `-n'. |
| 17071 | * data/bison.simple, data/bison.c++ (b4_lhs_value) |

| 17120 | * tests/calc.at: Exercise prologue splitting. |
| 17121 | |
| 17122 | * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and |

| 17126 | muscles. |

| 17132 | (read_declarations): Pass pre_prologue_obstack to copy_definition if |
| 17133 | `%union' has not yet been seen, pass post_prologue_obstack otherwise. |
| 17134 | |
| 17135 | 2002-04-23 Paul Eggert <eggert@twinsun.com> |
| 17136 | |
| 17137 | * data/bison.simple: Remove unnecessary commentary and white |
| 17138 | space differences from 1_29-branch. |

| 17157 | |
| 17158 | * src/reduce.c (dump_grammar): Move to... |
| 17159 | * src/gram.h, src/gram.c (grammar_dump): here. |
| 17160 | Be sure to separate long item numbers. |

| 17163 | 2002-04-22 Akim Demaille <akim@epita.fr> |

| 17176 | |
| 17177 | * src/reader.c (token_translations_init): 256 is now the default |
| 17178 | value for the error token, i.e., it will be assigned another |
| 17179 | number if the user assigned 256 to one of her tokens. |
| 17180 | (reader): Don't force 256 to error. |
| 17181 | * doc/bison.texinfo (Symbols): Adjust. |

| 17183 | (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3 |
| 17184 | etc. instead of 10, 20, 30 (which was used to `jump' over error |
| 17185 | (256) and undefined (2)). |
| 17186 | |
| 17187 | 2002-04-22 Akim Demaille <akim@epita.fr> |
| 17188 | |
| 17189 | Propagate more token_number_t. |

| 17192 | (item_number_as_token_number): New. |
| 17193 | * src/output.c (GENERATE_OUTPUT_TABLE): New. |
| 17194 | Use it to create output_item_number_table and |

| 17202 | |
| 17203 | * src/output.h, src/output.c (get_lines_number): Remove. |

| 17218 | |
| 17219 | * src/system.h: Rely on HAVE_LIMITS_H. |
| 17220 | Suggested by Paul Eggert. |
| 17221 | |
| 17222 | 2002-04-09 Akim Demaille <akim@epita.fr> |
| 17223 | |
| 17224 | * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the |
| 17225 | full stderr, and strip it according to the bison options, instead |
| 17226 | of composing the error message from different bits. |
| 17227 | This makes it easier to check for several error messages. |
| 17228 | Adjust all the invocations. |
| 17229 | Add an invocation exercising the error token. |
| 17230 | Add an invocation demonstrating a stupid error message. |
| 17231 | (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0. |
| 17232 | Adjust the tests. |

| 17236 | |
| 17237 | * src/gram.h, src/gram.c (error_token_number): Remove, use |
| 17238 | errtoken->number. |
| 17239 | * src/reader.c (reader): Don't specify the user token number (2) |
| 17240 | for $undefined, as it uselessly prevents using it. |
| 17241 | * src/gram.h (token_number_t): Move to... |
| 17242 | * src/symtab.h: here. |
| 17243 | (state_t.number): Is a token_number_t. |
| 17244 | * src/print.c, src/reader.c: Use undeftoken->number instead of |
| 17245 | hard coded 2. |
| 17246 | (Even though this 2 is not the same as above: the number of the |
| 17247 | undeftoken remains being 2, it is its user token number which |
| 17248 | might not be 2). |
| 17249 | * src/output.c (prepare_tokens): Rename the `maxtok' muscle with |
| 17250 | `user_token_number_max'. |
| 17251 | Output `undef_token_number'. |
| 17252 | * data/bison.simple, data/bison.c++: Use them. |
| 17253 | Be sure to map invalid yylex return values to |
| 17254 | `undef_token_number'. This saves us from gratuitous SEGV. |
| 17255 | |
| 17256 | * tests/conflicts.at (Solved SR Conflicts) |
| 17257 | (Unresolved SR Conflicts): Adjust. |
| 17258 | * tests/regression.at (Web2c Actions): Adjust. |
| 17259 | |
| 17260 | 2002-04-08 Akim Demaille <akim@epita.fr> |
| 17261 | |
| 17262 | * data/bison.c++: s/b4_item_number_max/b4_rhs_number_max/. |
| 17263 | Adding #line. |
| 17264 | Remove the duplicate `typedefs'. |
| 17265 | (RhsNumberType): Fix the declaration and various other typos. |
| 17266 | Use __ofile__. |
| 17267 | * data/bison.simple: Use __ofile__. |

| 17269 | |
| 17270 | 2002-04-08 Akim Demaille <akim@epita.fr> |
| 17271 | |
| 17272 | * src/gram.h (item_number_t): New, the type of item numbers in |
| 17273 | RITEM. Note that it must be able to code symbol numbers as |
| 17274 | positive number, and the negation of rule numbers as negative |
| 17275 | numbers. |
| 17276 | Adjust all dependencies (pretty many). |
| 17277 | * src/reduce.c (rule): Remove this `short *' pointer: use |
| 17278 | item_number_t. |
| 17279 | * src/system.h (MINSHORT, MAXSHORT): Remove. |
| 17280 | Include `limits.h'. |
| 17281 | Adjust dependencies to using SHRT_MAX and SHRT_MIN. |
| 17282 | (shortcpy): Remove. |
| 17283 | (MAXTABLE): Move to... |
| 17284 | * src/output.c (MAXTABLE): here. |
| 17285 | (prepare_rules): Use output_int_table to output rhs. |
| 17286 | * data/bison.simple, data/bison.c++: Adjust. |
| 17287 | * tests/torture.at (Big triangle): Move the limit from 254 to |
| 17288 | 500. |
| 17289 | * tests/regression.at (Web2c Actions): Ajust. |
| 17290 | |
| 17291 | Trying with bigger grammars shows various phenomena: at 3000 (28Mb |
| 17292 | of grammar file) bison is killed by my system, at 2000 (12Mb) bison |
| 17293 | passes, but produces negative #line number, once fixed, GCC is |
| 17294 | killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of |
| 17295 | C), it passes. |
| 17296 | * src/state.h (state_h): Code input lines on ints, not shorts. |

| 17310 | * src/output.c (output_table_data): Return the longest number. |
| 17311 | (prepare_tokens): Output `token_number_max'). |
| 17312 | * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type): |
| 17313 | New. |
| 17314 | Use them to define yy_token_number_type/TokenNumberType. |
| 17315 | Use this type for yytranslate. |
| 17316 | * tests/torture.at (Big triangle): Push the limit from 124 to |
| 17317 | 253. |

| 17388 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17389 | |
| 17390 | * src/gram.h (rule_s): prec and precsym are now pointers |
| 17391 | to the bucket giving the priority/associativity. |
| 17392 | Member `associativity' removed: useless. |
| 17393 | * src/reduce.c, src/conflicts.c: Adjust. |
| 17394 | |
| 17395 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17396 | |
| 17397 | * src/lalr.c, src/LR0.c, src/closure.c, src/gram.c, src/reduce.c: |
| 17398 | Properly escape the symbols' TAG when outputting them. |
| 17399 | |
| 17400 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17401 | |
| 17402 | * src/lalr.h (LA): Is a bitsetv, not bitset*. |
| 17403 | |
| 17404 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17405 | |
| 17406 | * src/lalr.h, src/lalr.c (LAruleno): Replace with... |
| 17407 | (LArule): this, which is an array to rule_t*. |
| 17408 | * src/print.c, src/conflicts.c: Adjust. |
| 17409 | |
| 17410 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17411 | |
| 17412 | * src/gram.h (rule_t): Rename `number' as `user_number'. |
| 17413 | `number' is a new member. |
| 17414 | Adjust dependencies. |
| 17415 | * src/reduce.c (reduce_grammar_tables): Renumber rule_t.number. |
| 17416 | |
| 17417 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17418 | |
| 17419 | As a result of the previous patch, it is no longer needed |
| 17420 | to reorder ritem itself. |
| 17421 | |
| 17422 | * src/reduce.c (reduce_grammar_tables): Don't sort RITEM. |
| 17423 | |
| 17424 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17425 | |
| 17426 | Be sure never to walk through RITEMS, but use only data related to |
| 17427 | the rules themselves. RITEMS should be banished. |
| 17428 | |
| 17429 | * src/output.c (output_token_translations): Rename as... |
| 17430 | (prepare_tokens): this. |
| 17431 | In addition to `translate', prepare the muscles `tname' and |
| 17432 | `toknum', which were handled by... |
| 17433 | (output_rule_data): this. |
| 17434 | Remove, and move the remainder of its outputs into... |
| 17435 | (prepare_rules): this new routines, which also merges content from |
| 17436 | (output_gram): this. |
| 17437 | (prepare_rules): Be sure never to walk through RITEMS. |
| 17438 | (output_stos): Rename as... |
| 17439 | (prepare_stos): this. |

| 17441 | in the output if you don't need it. |
| 17442 | |
| 17443 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17444 | |
| 17445 | * src/LR0.c (new_state): Display `nstates' as the name of the |
| 17446 | newly created state. |
| 17447 | Adjust to initialize first_state and last_state if needed. |
| 17448 | Be sure to distinguish the initial from the final state. |
| 17449 | (new_states): Create the itemset of the initial state, and use |
| 17450 | new_state. |
| 17451 | * src/closure.c (closure): Now that the initial state has its |
| 17452 | items properly set, there is no need for a special case when |
| 17453 | creating `ruleset'. |
| 17454 | |
| 17455 | As a result, now the rule 0, reducing to $axiom, is visible in the |
| 17456 | outputs. Adjust the test suite. |
| 17457 | |
| 17458 | * tests/conflicts.at (Solved SR Conflicts) |
| 17459 | (Unresolved SR Conflicts): Adjust. |
| 17460 | * tests/regression.at (Web2c Report, Rule Line Numbers): Idem. |

| 17464 | |
| 17465 | * src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over |
| 17466 | the RHS of the rules. |
| 17467 | * src/output.c (output_gram): Likewise. |
| 17468 | |
| 17469 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17470 | |
| 17471 | * src/gram.h (rule_t): `lhs' is now a pointer to the symbol's |
| 17472 | bucket. |
| 17473 | Adjust all dependencies. |
| 17474 | * src/reduce.c (nonterminals_reduce): Don't forget to renumber the |
| 17475 | `number' of the buckets too. |
| 17476 | * src/gram.h: Include `symtab.h'. |
| 17477 | (associativity): Move to... |
| 17478 | * src/symtab.h: here. |
| 17479 | No longer include `gram.h'. |
| 17480 | |
| 17481 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17482 | |
| 17483 | * src/gram.h, src/gram.c (rules_rhs_length): New. |
| 17484 | (ritem_longest_rhs): Use it. |
| 17485 | * src/gram.h (rule_t): `number' is a new member. |
| 17486 | * src/reader.c (packgram): Set it. |
| 17487 | * src/reduce.c (reduce_grammar_tables): Move the useless rules at |
| 17488 | the end of `rules', and count them out of `nrules'. |
| 17489 | (reduce_output, dump_grammar): Adjust. |
| 17490 | * src/print.c (print_grammar): It is no longer needed to check for |
| 17491 | the usefulness of a rule, as useless rules are beyond `nrules + 1'. |
| 17492 | * tests/reduce.at (Reduced Automaton): New test. |
| 17493 | |
| 17494 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17495 | |
| 17496 | * src/reduce.c (inaccessable_symbols): Fix a buglet: because of a |
| 17497 | lacking `+ 1' to nrules, Bison reported as useless a token if it |
| 17498 | was used solely to set the precedence of the last rule... |
| 17499 | |
| 17500 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17501 | |
| 17502 | * data/bison.c++, data/bison.simple: Don't output the current file |
| 17503 | name in #line, to avoid useless diffs between two identical |
| 17504 | outputs under different names. |
| 17505 | |
| 17506 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17507 | |
| 17508 | * src/closure.c, src/print.c, src/reader.c, src/reduce.c: |
| 17509 | Normalize loops to using `< nrules + 1', not `<= nrules'. |
| 17510 | |
| 17511 | 2002-04-07 Akim Demaille <akim@epita.fr> |
| 17512 | |
| 17513 | * TODO: Update. |
| 17514 | |
| 17515 | 2002-04-07 Akim Demaille <akim@epita.fr> |

| 17751 | * src/closure.c (fderives): Be an array of bitsets. |
| 17752 | |
| 17753 | 2002-02-28 Robert Anisko <robert@lrde.epita.fr> |
| 17754 | |
| 17755 | * data/bison.c++: Merge the two generated headers. Insert a copyright |
| 17756 | notice in each output file. |
| 17757 | |
| 17758 | 2002-02-28 Akim Demaille <akim@epita.fr> |
| 17759 | |
| 17760 | * data/bison.c++: Copy the prologue of bison.simple to fetch |
| 17761 | useful M4 definitions, such as b4_header_guard. |
| 17762 | |
| 17763 | 2002-02-25 Akim Demaille <akim@epita.fr> |
| 17764 | |
| 17765 | * src/getargs.c (version): Give the name of the authors, and use a |
| 17766 | translator friendly scheme for the bgr |
| 17767 | copyright notice. |
| 17768 | |
| 17769 | 2002-02-25 Akim Demaille <akim@epita.fr> |
| 17770 | |
| 17771 | * src/output.c (header_output): Remove, now handled completely via |
| 17772 | M4. |
| 17773 | |
| 17774 | 2002-02-25 Akim Demaille <akim@epita.fr> |
| 17775 | |
| 17776 | * m4/m4.m4: New, from CVS Autoconf. |
| 17777 | * configure.in: Invoke it. |
| 17778 | * src/output.c (output_skeleton): Use its result instead of the |
| 17779 | hard coded name. |
| 17780 | |
| 17781 | 2002-02-25 Akim Demaille <akim@epita.fr> |
| 17782 | |
| 17783 | * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from |
| 17784 | Fileutils 4.1.5. |

| 17791 | (prepare): here. |
| 17792 | * src/system.h (DEFAULT_TMPDIR): New. |
| 17793 | |
| 17794 | 2002-02-14 Paul Eggert <eggert@twinsun.com> |
| 17795 | |
| 17796 | Remove the support for C++ namespace cleanliness; it was |
| 17797 | causing more problems than it was curing, since it didn't work |
| 17798 | properly on some nonstandard C++ compilers. This can wait |
| 17799 | for a proper C++ parser. |
| 17800 | |
| 17801 | * NEWS: Document this. |
| 17802 | * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention |
| 17803 | of C++, as it's treated like C now. |
| 17804 | * src/bison.simple (YYSTD): Remove. |
| 17805 | (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL): |
| 17806 | Treat C++ just like Standard C instead of trying to support |
| 17807 | namespace cleanliness. |
| 17808 | |
| 17809 | 2002-02-14 Akim Demaille <akim@epita.fr> |
| 17810 | |
| 17811 | * tests/regression.at (else): Adjust to Andreas' change. |
| 17812 | |
| 17813 | 2002-02-14 Akim Demaille <akim@epita.fr> |
| 17814 | |
| 17815 | * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c. |
| 17816 | |
| 17817 | 2002-02-13 Andreas Schwab <schwab@suse.de> |
| 17818 | |
| 17819 | * src/output.c (output_rule_data): Don't output NULL, it might |
| 17820 | not be defined yet. |
| 17821 | |
| 17822 | 2002-02-11 Robert Anisko <robert@lrde.epita.fr> |
| 17823 | |
| 17824 | * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue. |
| 17825 | (Copyright notice): Update. |
| 17826 | |
| 17827 | 2002-02-11 Akim Demaille <akim@epita.fr> |
| 17828 | |
| 17829 | * tests/regression.at (%nonassoc and eof): Don't include |
| 17830 | nonportable headers. |
| 17831 | |
| 17832 | 2002-02-08 Robert Anisko <robert@lrde.epita.fr> |
| 17833 | |
| 17834 | * data/bison.c++: Correct error recovery. Make the user able to |
| 17835 | initialize the starting location. |
| 17836 | |
| 17837 | 2002-02-07 Akim Demaille <akim@epita.fr> |
| 17838 | |
| 17839 | * tests/input.at: New. |
| 17840 | |
| 17841 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 17842 | |
| 17843 | * data/bison.c++: Replace some direct m4 expansions by constants. Be |
| 17844 | more consistent when naming methods and variables. Put preprocessor |
| 17845 | directives around tables only needed for debugging. |
| 17846 | |
| 17847 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 17848 | |
| 17849 | * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in |
| 17850 | C++ parsers. |
| 17851 | (yy::b4_name::parse): Use print_. |
| 17852 | |
| 17853 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 17854 | |
| 17855 | * data/bison.c++ (yy::b4_name::parse): Error recovery is back. |
| 17856 | |
| 17857 | 2002-02-07 Robert Anisko <robert@lrde.epita.fr> |
| 17858 | |
| 17859 | * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in |
| 17860 | C++ parsers. |
| 17861 | (yy::b4_name::parse): Build verbose error messages, and use error_. |
| 17862 | |
| 17863 | 2002-02-06 Robert Anisko <robert@lrde.epita.fr> |
| 17864 | |
| 17865 | * data/bison.c++: Fix m4 quoting in comments. |
| 17866 | |
| 17867 | 2002-02-06 Robert Anisko <robert@lrde.epita.fr> |
| 17868 | |
| 17869 | * data/bison.c++: Adjust the parser code. Fix some muscles that were |
| 17870 | not expanded by m4. |
| 17871 | |
| 17872 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 17873 | |
| 17874 | * data/bison.c++: Adjust to the M4 back end. |
| 17875 | More is certainly needed. |
| 17876 | |
| 17877 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 17878 | |
| 17879 | Give a try to M4 as a back end. |
| 17880 | |
| 17881 | * lib/readpipe.c: New, from wdiff. |
| 17882 | * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and |
| 17883 | BISON_HAIRY. |
| 17884 | * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS |
| 17885 | specific values. Now it is m4 that performs the lookup. |
| 17886 | * src/parse-skel.y: Remove. |
| 17887 | * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New. |
| 17888 | * src/output.c (actions_output, guards_output) |
| 17889 | (token_definitions_output): No longer keeps track of the output |
| 17890 | line number, hence remove the second argument. |
| 17891 | (guards_output): Check against the guard member of a rule, not the |
| 17892 | action member. |
| 17893 | Adjust callers. |
| 17894 | (output_skeleton): Don't look for the skeleton location, let m4 do |
| 17895 | that. |
| 17896 | Create `/tmp/muscles.m4'. This is temporary, a proper temporary |
| 17897 | file will be used. |
| 17898 | Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton. |
| 17899 | (prepare): Given that for the time being changesyntax is not |
| 17900 | usable in M4, rename the muscles using `-' to `_'. |
| 17901 | Define `defines_flag', `output_parser_name' and `output_header_name'. |
| 17902 | * src/output.h (actions_output, guards_output) |
| 17903 | (token_definitions_output): Adjust prototypes. |
| 17904 | * src/scan-skel.l: Instead of scanning the skeletons, it now |
| 17905 | processes the output of m4: `__oline__' and `#output'. |
| 17906 | * data/bison.simple: Adjust to be used by M4(sugar). |
| 17907 | * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up |
| 17908 | to date. |
| 17909 | * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR' |
| 17910 | instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'. |
| 17911 | * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New, |
| 17912 | shamelessly stolen from CVS Autoconf. |
| 17913 | |
| 17914 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 17915 | |
| 17916 | * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version. |
| 17917 | * configure.in: Check for the declarations of free and malloc. |
| 17918 | * src/muscle_tab.c: Adjust. |
| 17919 | |
| 17920 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 17921 | |
| 17922 | * src/muscle_tab.c (muscle_init): Don't default to NULL muscle |
| 17923 | which have no values. |
| 17924 | |
| 17925 | 2002-02-05 Akim Demaille <akim@epita.fr> |
| 17926 | |
| 17927 | * src/bison.simple, src/bison.hairy, src/bison.c++: Move to... |
| 17928 | * data/: here. |
| 17929 | |
| 17930 | 2002-01-29 Paul Eggert <eggert@twinsun.com> |
| 17931 | |
| 17932 | * src/bison.simple (YYSIZE_T): Do not define merely because |
| 17933 | YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined. |
| 17934 | On some platforms, <alloca.h> does not declare YYSTD (size_t). |
| 17935 | |
| 17936 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 17937 | |
| 17938 | Fix `%nonassoc and eof'. |
| 17939 | |
| 17940 | * src/state.c (errs_dup): Aaaah! The failure was due to bytes |
| 17941 | which were not properly copied! Replace |
| 17942 | memcpy (res->errs, src->errs, src->nerrs); |
| 17943 | with |
| 17944 | memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0])); |
| 17945 | !!! |
| 17946 | * tests/regression.at (%nonassoc and eof): Adjust to newest |
| 17947 | Autotest: `.' is not in the PATH. |
| 17948 | |
| 17949 | 2002-01-27 Akim Demaille <akim@epita.fr> |
| 17950 | |
| 17951 | * tests/sets.at (AT_EXTRACT_SETS): New. |
| 17952 | (Nullable): Use it. |
| 17953 | (Firsts): New. |

| 17955 | 2002-01-26 Akim Demaille <akim@epita.fr> |
| 17956 | |
| 17957 | * tests/actions.at, tests/calc.at, tests/headers.at, |
| 17958 | * tests/torture.at: Adjust to the newest Autotest which no longer |
| 17959 | forces `.' in the PATH. |
| 17960 | |
| 17961 | 2002-01-25 Akim Demaille <akim@epita.fr> |
| 17962 | |
| 17963 | * tests/regression.at (%nonassoc and eof): New. |
| 17964 | Suggested by Robert Anisko. |
| 17965 | |
| 17966 | 2002-01-24 Akim Demaille <akim@epita.fr> |
| 17967 | |
| 17968 | Bison dumps core when trying to complain about broken input files. |
| 17969 | Reported by Cris van Pelt. |
| 17970 | |
| 17971 | * src/lex.c (parse_percent_token): Be sure to set token_buffer. |
| 17972 | * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge |
| 17973 | into... |
| 17974 | (Invalid inputs): Strengthen: exercise parse_percent_token. |
| 17975 | |
| 17976 | 2002-01-24 Robert Anisko <robert.anisko@epita.fr> |
| 17977 | |
| 17978 | * src/Makefile.am: Add bison.c++. |
| 17979 | * src/bison.c++: New skeleton. |
| 17980 | |
| 17981 | 2002-01-21 Paolo Bonzini <bonzini@gnu.org> |
| 17982 | |
| 17983 | * po/it.po: New. |
| 17984 | |
| 17985 | 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net> |
| 17986 | |
| 17987 | * src/files.c (skeleton_find) [MSDOS]: Fix cp definition. |
| 17988 | |
| 17989 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 17990 | |
| 17991 | * src/files.c (compute_output_file_names): Fix |
| 17992 | |
| 17993 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 17994 | |
| 17995 | * tests/output.at: New test. |
| 17996 | * src/files.c (compute_base_names): Don't map extensions when |
| 17997 | the YACC flag is set, use defaults. |
| 17998 | Reported by Evgeny Stambulchik. |
| 17999 | |
| 18000 | 2002-01-20 Marc Autret <marc@gnu.org> |
| 18001 | |
| 18002 | * src/system.h: Need to define __attribute__ away for non-GCC |
| 18003 | compilers as well (i.e., the vendor C compiler). |
| 18004 | Suggested by Albert Chin-A-Young. |
| 18005 | |
| 18006 | 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be> |
| 18007 | |
| 18008 | * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the |
| 18009 | canonical definition. |
| 18010 | * src/system.h: Use the canonical definition for PARAMS (avoids |
| 18011 | a conflict with the macro from lib/hash.h). |
| 18012 | |
| 18013 | 2002-01-11 Akim Demaille <akim@epita.fr> |
| 18014 | |
| 18015 | * configure.in: Use AC_FUNC_STRNLEN. |
| 18016 | Fixes the failures observed on AIX 4.3 by H.Merijn Brand. |
| 18017 | |
| 18018 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 18019 | |
| 18020 | * src/files.c, src/files.h (output_infix): New. |
| 18021 | (tab_extension): Remove. |
| 18022 | (compute_base_names): Compute the former, drop the latter. |
| 18023 | * src/output.c (prepare): Insert the muscles `output-infix', and |
| 18024 | `output-suffix'. |
| 18025 | * src/parse-skel.y (string, string.1): New. |
| 18026 | (section.header): Use it. |
| 18027 | (section.yacc): Remove. |
| 18028 | (prefix): Remove too. |
| 18029 | * src/scan-skel.l: Adjust. |
| 18030 | * src/bison.simple, src/bison.hairy: Adjust. |
| 18031 | |
| 18032 | 2002-01-09 Akim Demaille <akim@epita.fr> |
| 18033 | |
| 18034 | * configure.in (WERROR_CFLAGS): Compute it. |
| 18035 | * src/Makefile.am (CFLAGS): Pass it. |
| 18036 | * tests/atlocal.in (CFLAGS): Idem. |
| 18037 | * src/files.c: Fix a few warnings. |
| 18038 | (get_extension_index): Remove, unused. |
| 18039 | |
| 18040 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 18041 | |
| 18042 | * src/getargs.c (AS_FILE_NAME): New. |
| 18043 | (getargs): Use it to convert DOSish file names. |
| 18044 | * src/files.c (base_name): Rename as full_base_name to avoid |
| 18045 | clashes with `base_name ()'. |
| 18046 | (filename_split): New. |
| 18047 | (compute_base_names): N-th rewrite, using filename_split. |
| 18048 | |
| 18049 | 2002-01-08 Akim Demaille <akim@epita.fr> |
| 18050 | |
| 18051 | * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c: |
| 18052 | New, stolen from the Fileutils 4.1. |
| 18053 | * lib/Makefile.am (libbison_a_SOURCES): Adjust. |
| 18054 | * configure.in: Check for the presence of memrchr, and of its |
| 18055 | prototype. |
| 18056 | |
| 18057 | 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be> |
| 18058 | |
| 18059 | * lib/hash.h (__P): Added definition for this macro. |
| 18060 | * src/Makefile.am: Add parse-skel.c and scan-skel.c to |
| 18061 | BUILT_SOURCES, to ensure they are generated first. |
| 18062 | * src/parse-skel.y: Use YYERROR_VERBOSE instead of |
| 18063 | %error-verbose to allow bootstrapping with bison 1.30x. |
| 18064 | |
| 18065 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 18066 | |
| 18067 | * src/reader.c (parse_braces): Don't fetch the next char, the |
| 18068 | convention is to fetch on entry. |
| 18069 | * tests/torture.at (GNU Cim Grammar): Reintroduce their weird |
| 18070 | 'switch' without a following semicolon. |
| 18071 | * tests/regression.at (braces parsing): New. |
| 18072 | |
| 18073 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 18074 | |
| 18075 | Bison is dead wrong in its RR conflict reports. |
| 18076 | |
| 18077 | * tests/torture.at (GNU Cim Grammar): New. |
| 18078 | * src/conflicts.c (count_rr_conflicts): Fix. |
| 18079 | |
| 18080 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 18081 | |
| 18082 | Creating package.m4 from configure.ac causes too many problems. |
| 18083 | |
| 18084 | * tests/Makefile.am (package.m4): Create it by hand, |
| 18085 | AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf. |
| 18086 | |
| 18087 | 2002-01-06 Akim Demaille <akim@epita.fr> |
| 18088 | |
| 18089 | * src/Makefile.am (bison_SOURCES): Add parse-skel.h and |
| 18090 | skeleton.h. |
| 18091 | |
| 18092 | 2002-01-04 Paul Eggert <eggert@twinsun.com> |
| 18093 | |
| 18094 | * doc/bison.texinfo (Debugging): |
| 18095 | Remove YYSTDERR; it's no longer defined or used. |
| 18096 | Also, s/cstdio.h/cstdio/. |
| 18097 | |
| 18098 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 18099 | |
| 18100 | * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf. |
| 18101 | |
| 18102 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 18103 | |
| 18104 | * src/parse-skel.y (process_skeleton): Don't bind the parser's |
| 18105 | tracing code to --trace, wait for a better --trace option, with |
| 18106 | args. |
| 18107 | |
| 18108 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 18109 | |
| 18110 | * src/bison.simple (YYSTDERR): Remove, replace `stderr'. |
| 18111 | The ISO C++ standard is extremely clear about it: stderr is |
| 18112 | considered a macro, not a regular symbol (see table 94 `Header |
| 18113 | <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files). |
| 18114 | Therefore std:: does not apply to it. It still does with fprintf. |
| 18115 | Also, s/cstdio.h/cstdio/. |
| 18116 | |
| 18117 | 2002-01-03 Akim Demaille <akim@epita.fr> |
| 18118 | |
| 18119 | * lib/quotearg.c: Use `#include "..."' instead of `#include <...>' |
| 18120 | for non system headers. |
| 18121 | |
| 18122 | 2002-01-02 Akim Demaille <akim@epita.fr> |
| 18123 | |
| 18124 | Equip the skeleton chain with location tracking, runtime trace, |
| 18125 | pure parser and scanner. |
| 18126 | |
| 18127 | * src/parse-skel.y: Request a pure parser, locations, and prefix |
| 18128 | renaming. |
| 18129 | (%union): Having several members with the same type does not help |
| 18130 | type mismatches, simplify. |
| 18131 | (YYPRINT, yyprint): New. |
| 18132 | (yyerror): ``Rename'' (there is a #define yyerror skel_error) as... |
| 18133 | (skel_error): this. |
| 18134 | Handle locations. |
| 18135 | * src/scan-skel.l: Adjust to these changes. |
| 18136 | * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP) |
| 18137 | (LOCATION_PRINT, skel_control_t): New. |
| 18138 | |
| 18139 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 18140 | |
| 18141 | * src/parse-skel.y: Get rid of the shift/reduce conflict: |
| 18142 | replace `gb' with BLANKS. |
| 18143 | * src/scan-skel.l: Adjust. |
| 18144 | |
| 18145 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 18146 | |
| 18147 | * src/system.h: We don't need nor want bcopy. |
| 18148 | Throw away MS-DOS crap: we don't need getpid. |
| 18149 | * configure.in: We don't need strndup. It was even causing |
| 18150 | problems: because Flex includes the headers *before* us, |
| 18151 | _GNU_SOURCE is not defined by config.h, and therefore strndup was |
| 18152 | not visible. |
| 18153 | * lib/xstrndup.c: New. |
| 18154 | * src/scan-skel.l: Use it. |
| 18155 | Be sure to initialize yylval.muscle member when scanning a MUSCLE. |
| 18156 | * src/parse-skel.y: Use %directives instead of #defines. |
| 18157 | |
| 18158 | 2001-12-30 Akim Demaille <akim@epita.fr> |
| 18159 | |
| 18160 | * src/skeleton.h: New. |
| 18161 | * src/output.c (output_parser, output_master_parser): Remove, dead |
| 18162 | code. |
| 18163 | * src/output.h (get_lines_number, actions_output, guards_output) |
| 18164 | (token_definitions_output): Prototype them. |
| 18165 | * src/parse-skel.y: Add the license notice. |
| 18166 | Include output.h and skeleton.h. |
| 18167 | (process_skeleton): Returns void, and takes a single parameter. |
| 18168 | * src/scan-skel.l: Add the license notice. |
| 18169 | Include skeleton.h. |
| 18170 | Don't use %option yylineno: it seems that then Flex imagines |
| 18171 | REJECT has been used, and therefore it won't reallocate its |
| 18172 | buffers (which makes no other sense to me than a bug). It results |
| 18173 | in warnings for `unused: yy_flex_realloc'. |
| 18174 | |
| 18175 | 2001-12-30 Robert Anisko <robert.anisko@epita.fr> |
| 18176 | |
| 18177 | * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 18178 | (MUSCLE_INSERT_PREFIX): ...to there. |
| 18179 | * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING) |
| 18180 | (MUSCLE_INSERT_PREFIX): Move from here... |
| 18181 | |
| 18182 | * src/bison.hairy: Add a section directive. Put braces around muscle |
| 18183 | names. This parser skeleton is still broken, but Bison should not |
| 18184 | choke on a bad muscle 'syntax'. |
| 18185 | * src/bison.simple: Add a section directive. Put braces around muscle |
| 18186 | names. |
| 18187 | |
| 18188 | * src/files.h (strsuffix, stringappend): Add declarations. |
| 18189 | (tab_extension): Add declaration. |
| 18190 | (short_base_name): Add declaration. |
| 18191 | |
| 18192 | * src/files.c (strsuffix, stringappend): No longer static. These |
| 18193 | functions are used in the skeleton parser. |
| 18194 | (tab_extension): New. |
| 18195 | (compute_base_names): Use the computations done in this function |
| 18196 | to guess if the generated parsers should have '.tab' in their |
| 18197 | names. |
| 18198 | (short_base_name): No longer static. |
| 18199 | |
| 18200 | * src/output.c (output_skeleton): New. |
| 18201 | (output): Disable call to output_master_parser, and give a try to |
| 18202 | a new skeleton handling system. |
| 18203 | (guards_output, actions_output): No longer static. |
| 18204 | (token_definitions_output, get_lines_number): No longer static. |
| 18205 | |
| 18206 | * configure.in: Use AM_PROG_LEX and AC_PROG_YACC. |
| 18207 | |
| 18208 | * src/Makefile.am (bison_SOURCES): Add scan-skel.l and |
| 18209 | parse-skel.y. |
| 18210 | |
| 18211 | * src/parse-skel.y: New file. |
| 18212 | * src/scan-skel.l: New file. |
| 18213 | |
| 18214 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18215 | |
| 18216 | %name-prefix is broken. |
| 18217 | |
| 18218 | * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy". |
| 18219 | Adjust all dependencies. |
| 18220 | * tests/headers.at (export YYLTYPE): Strengthen this test: use |
| 18221 | %name-prefix. |
| 18222 | |
| 18223 | Renaming yylval but not yylloc is not consistent. Now we do. |
| 18224 | |
| 18225 | * src/bison.simple: Prefix yylloc if used. |
| 18226 | * doc/bison.texinfo (Decl Summary): Document that. |
| 18227 | |
| 18228 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18229 | |
| 18230 | * doc/bison.texinfo: Promote `%long-directive' over |
| 18231 | `%long_directive'. |
| 18232 | Remove all references to fixed-output-files, yacc is enough. |
| 18233 | |
| 18234 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18235 | |
| 18236 | * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the |
| 18237 | user prologue. These are defaults. |
| 18238 | * tests/actions.at (Mid-rule actions): Make sure the user can |
| 18239 | define YYDEBUG and YYERROR_VERBOSE. |
| 18240 | |
| 18241 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18242 | |
| 18243 | * src/output.c (header_output): Don't forget to export YYLTYPE and |
| 18244 | yylloc. |
| 18245 | * tests/headers.at (export YYLTYPE): New, make sure it does. |
| 18246 | * tests/regression.at (%union and --defines, Invalid CPP headers): |
| 18247 | Move to... |
| 18248 | * tests/headers.at: here. |
| 18249 | |
| 18250 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18251 | |
| 18252 | * src/gram.h (rule_s): Member `assoc' is of type `associativity'. |
| 18253 | |
| 18254 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18255 | |
| 18256 | * tests/actions.at (Mid-rule actions): Output on a single line |
| 18257 | instead of several. |
| 18258 | |
| 18259 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18260 | |
| 18261 | * doc/bison.texinfo: Formatting changes. |
| 18262 | |
| 18263 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18264 | |
| 18265 | Don't store the token defs in a muscle, just be ready to output it |
| 18266 | on command. Now possible via `symbols'. Fixes a memory leak. |
| 18267 | |
| 18268 | * src/output.c (token_definitions_output): New. |
| 18269 | (output_parser, header_output): Use it. |
| 18270 | * src/reader.c (symbols_save): Remove. |
| 18271 | |
| 18272 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18273 | |
| 18274 | * src/bison.simple: Do not provide a default for YYSTYPE and |
| 18275 | YYLTYPE before the user's prologue. Otherwise it's hardly... a |
| 18276 | default. |
| 18277 | |
| 18278 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18279 | |
| 18280 | Mid-rule actions are simply... ignored! |
| 18281 | |
| 18282 | * src/reader.c (readgram): Be sure to attach mid-rule actions to |
| 18283 | the empty-rule associated to the dummy symbol, not to the host |
| 18284 | rule. |
| 18285 | * tests/actions.at (Mid-rule actions): New. |
| 18286 | |
| 18287 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18288 | |
| 18289 | Memory leak. |
| 18290 | |
| 18291 | * src/reader.c (reader): Free grammar. |
| 18292 | |
| 18293 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18294 | |
| 18295 | Memory leak. |
| 18296 | |
| 18297 | * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here, |
| 18298 | since it allocates it for each state, although only one is needed. |
| 18299 | (allocate_storage): Do it here. |
| 18300 | |
| 18301 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18302 | |
| 18303 | * src/options.h, src/options.c (create_long_option_table): Rename |
| 18304 | as... |
| 18305 | (long_option_table_new): this, with a clearer prototype. |
| 18306 | (percent_table): Remove, unused, |
| 18307 | * src/getargs.c (getargs): Adjust. |
| 18308 | |
| 18309 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18310 | |
| 18311 | * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c |
| 18312 | * src/print.c, src/print_graph.c, src/state.h: Rename state_table |
| 18313 | as states. |
| 18314 | |
| 18315 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18316 | |
| 18317 | * src/lalr.c (build_relations): Rename `states' as `states1'. |
| 18318 | Sorry, I don't understand exactly what it is, no better name... |
| 18319 | |
| 18320 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18321 | |
| 18322 | * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c |
| 18323 | * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c |
| 18324 | * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table |
| 18325 | as rules. |
| 18326 | |
| 18327 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18328 | |
| 18329 | * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long |
| 18330 | ago. |
| 18331 | |
| 18332 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18333 | |
| 18334 | * src/reader.c, src/reader.h (user_toknums): Remove. |
| 18335 | Adjust all users to use symbols[i]->user_token_number. |
| 18336 | |
| 18337 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18338 | |
| 18339 | * src/gram.c, src/gram.h (sprec, sassoc): Remove. |
| 18340 | Adjust all users to use symbols[i]->prec or ->assoc. |
| 18341 | |
| 18342 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18343 | |
| 18344 | * src/reader.c, src/reader.h (tags): Remove. |
| 18345 | Adjust all users to use symbols[i]->tag. |
| 18346 | |
| 18347 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18348 | |
| 18349 | * src/gram.h, src/gram.c (symbols): New, similar to state_table |
| 18350 | and rule_table. |
| 18351 | * src/reader.c (packsymbols): Fill this table. |
| 18352 | Drop sprec. |
| 18353 | * src/conflicts.c (resolve_sr_conflict): Adjust. |
| 18354 | * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a |
| 18355 | single table. |
| 18356 | Use symbols[i]->tag instead of tags[i]. |
| 18357 | |
| 18358 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18359 | |
| 18360 | * tests/calc.at (_AT_DATA_CALC_Y): Also use %union. |
| 18361 | In addition, put a comment in there, to replace... |
| 18362 | * tests/regression.at (%union and C comments): Remove. |
| 18363 | |
| 18364 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18365 | |
| 18366 | * tests/regression.at (Web2c Actions): Blindly move the actual |
| 18367 | output as expected output. The contents *seem* right to me, but I |
| 18368 | can't pretend reading perfectly parser tables... Nonetheless, all |
| 18369 | the other tests pass correctly, the table look OK, even though the |
| 18370 | presence of `$axiom' is to be noted: AFAICS it is useless (but |
| 18371 | harmless). |
| 18372 | |
| 18373 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18374 | |
| 18375 | * src/reader.c (readgram): Don't add the rule 0 if there were no |
| 18376 | rules read. In other words, add it _after_ having performed |
| 18377 | grammar sanity checks. |
| 18378 | Fixes the `tests/regression.at (Invalid input: 1)' Failure. |
| 18379 | |
| 18380 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18381 | |
| 18382 | * tests/regression.at (Web2c Report): Catch up: the rule 0 is now |
| 18383 | visible, and some states have now a different number. |
| 18384 | |
| 18385 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18386 | |
| 18387 | * src/reader.c (readgram): Bind the initial rule's lineno to that |
| 18388 | of the first rule. |
| 18389 | * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts): |
| 18390 | (Solved SR Conflicts): Adjust rule 0's line number. |
| 18391 | |
| 18392 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18393 | |
| 18394 | Fix the `GAWK Grammar' failure. |
| 18395 | |
| 18396 | * src/LR0.c (final_state): Initialize to -1 so that we do compute |
| 18397 | the reductions of the first state which was mistakenly confused |
| 18398 | with the final state because precisely final_state was initialized |
| 18399 | to 0. |
| 18400 | * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads, |
| 18401 | now noticed by Bison. |
| 18402 | * tests/regression.at (Rule Line Numbers): Adjust: state 0 does |
| 18403 | have a reduction on $default. |
| 18404 | |
| 18405 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18406 | |
| 18407 | * src/gram.c (ritem_print): Be sure to subtract 1 when displaying |
| 18408 | rule line numbers. |
| 18409 | * src/closure.c (print_closure): Likewise. |
| 18410 | * src/derives.c (print_derives): Likewise. |
| 18411 | * tests/sets.at (Nullable): Adjust: the rule numbers are correct |
| 18412 | now. |
| 18413 | |
| 18414 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18415 | |
| 18416 | * src/lalr.c (lookaheads_print): New. |
| 18417 | (lalr): Call it when --trace-flag. |
| 18418 | * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads |
| 18419 | are dumped. |
| 18420 | |
| 18421 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18422 | |
| 18423 | * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0', |
| 18424 | when walking through ritem, even via rule->rhs. |
| 18425 | * src/reduce.c (dump_grammar, useful_production, reduce_output) |
| 18426 | (useful_production, useless_nonterminals): Likewise. |
| 18427 | (reduce_grammar_tables): Likewise, plus update nritems. |
| 18428 | * src/nullable.c (set_nullable): Likewise. |
| 18429 | * src/lalr.c (build_relations): Likewise. |
| 18430 | * tests/sets.at (Nullable): Adjust. |
| 18431 | Fortunately, now, the $axiom is no longer nullable. |
| 18432 | |
| 18433 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18434 | |
| 18435 | * src/LR0.c (generate_states): Use nritems, not nitems, nor using |
| 18436 | the 0-sentinel. |
| 18437 | * src/gram.c (ritem_longest_rhs): Likewise. |
| 18438 | * src/reduce.c (nonterminals_reduce): Likewise. |
| 18439 | * src/print_graph.c (print_graph): Likewise. |
| 18440 | * src/output.c (output_rule_data): Likewise. |
| 18441 | * src/nullable.c (set_nullable): Likewise. |
| 18442 | |
| 18443 | 2001-12-29 Akim Demaille <akim@epita.fr> |
| 18444 | |
| 18445 | * src/output.c: Comment changes. |
| 18446 | |
| 18447 | 2001-12-27 Paul Eggert <eggert@twinsun.com> |
| 18448 | |
| 18449 | * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special |
| 18450 | cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and |
| 18451 | Sparc, as they were causing more porting problems than the |
| 18452 | (minor) performance improvement was worth. |
| 18453 | |
| 18454 | Also, catch up with 1.31's YYSTD. |
| 18455 | |
| 18456 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18457 | |
| 18458 | * src/output.c (output_gram): Rely on nritems, not the |
| 18459 | 0-sentinel. See below. |
| 18460 | Use -1 as separator, not 0. |
| 18461 | * src/bison.simple (yyparse): Subtract 1 to the rule numbers. |
| 18462 | Rely on -1 as separator in yyrhs, instead of 0. |
| 18463 | * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue |
| 18464 | twice `Now at end of input', therefore there are two lines less to |
| 18465 | expect. |
| 18466 | |
| 18467 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18468 | |
| 18469 | * tests/regression.at (Unresolved SR Conflicts): |
| 18470 | (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes |
| 18471 | below. |
| 18472 | |
| 18473 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18474 | |
| 18475 | * src/LR0.c (new_state): Recognize the final state by the fact it |
| 18476 | is reached by eoftoken. |
| 18477 | (insert_start_shifting_state, insert_eof_shifting_state) |
| 18478 | (insert_accepting_state, augment_automaton): Remove, since now |
| 18479 | these states are automatically computed from the initial state. |
| 18480 | (generate_states): Adjust. |
| 18481 | * src/print.c: When reporting a rule number to the user, substract |
| 18482 | 1, so that the axiom rule is rule 0, and the first user rule is 1. |
| 18483 | * src/reduce.c: Likewise. |
| 18484 | * src/print_graph.c (print_core): For the time being, just as for |
| 18485 | the report, depend upon --trace-flags to dump the full set of |
| 18486 | items. |
| 18487 | * src/reader.c (readgram): Once the grammar read, insert the rule |
| 18488 | 0: `$axiom: START-SYMBOL $'. |
| 18489 | * tests/set.at: Adjust: rule 0 is now displayed, and since the |
| 18490 | number of the states has changed (the final state is no longer |
| 18491 | necessarily the last), catch up. |

| 18494 | |
| 18495 | Try to make the use of the eoftoken valid. Given that its value |
| 18496 | is 0 which was also used as a sentinel in ritem, (i) make sure >= 0 |
| 18497 | is used instead of > 0 where appropriate, (ii), depend upon nritems |
| 18498 | instead of the 0-sentinel. |
| 18499 | |
| 18500 | * src/gram.h, src/gram.c (nritems): New. |
| 18501 | Expected to be duplication of nitems, but for the time being... |
| 18502 | * src/reader.c (packgram): Assert nritems and nitems are equal. |
| 18503 | * src/LR0.c (allocate_itemsets, new_itemsets): Adjust. |
| 18504 | * src/closure.c (print_closure, print_fderives): Likewise. |
| 18505 | * src/gram.c (ritem_print): Likewise. |
| 18506 | * src/print.c (print_core, print_grammar): Likewise. |
| 18507 | * src/print_graph.c: Likewise. |
| 18508 | |
| 18509 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18510 | |
| 18511 | * src/main.c (main): If there are complains after grammar |
| 18512 | reductions, then output the report anyway if requested, then die. |
| 18513 | * src/symtab.c (bucket_new): Initialize `value' to -1, not 0. |
| 18514 | * src/reader.c (eoftoken): New. |
| 18515 | (parse_token_decl): If the token being defined has value `0', it |
| 18516 | is the eoftoken. |
| 18517 | (packsymbols): No longer hack `tags' to insert `$' by hand. |
| 18518 | Be sure to preserve the value of the eoftoken. |
| 18519 | (reader): Make sure eoftoken is defined. |
| 18520 | Initialize nsyms to 0: now eoftoken is created just like the others. |
| 18521 | * src/print.c (print_grammar): Don't special case the eof token. |
| 18522 | * src/regression.at: Adjust: `$' has value 0, not -1, which was a |
| 18523 | lie anyway, albeit pleasant. |
| 18524 | * tests/calc.at: Exercise error messages with eoftoken. |
| 18525 | Change the grammar so that empty input is invalid. |
| 18526 | Adjust expectations. |
| 18527 | When yyungeting, be sure to use a valid yylloc: use last_yylloc. |
| 18528 | |
| 18529 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18530 | |
| 18531 | * configure.in: Check the protos of strchr ans strspn. |
| 18532 | Replace strchr if needed. |
| 18533 | * src/system.h: Provide the protos of strchr, strspn and memchr if |
| 18534 | missing. |
| 18535 | * lib/strchr.c: New. |
| 18536 | * src/reader.c (symbols_save): Use strchr. |
| 18537 | |
| 18538 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18539 | |
| 18540 | * src/print.c, src/print_graph.c (escape): New. |
| 18541 | Use it to quote the TAGS outputs. |
| 18542 | * src/print_graph.c (print_state): Now errors are in red, and |
| 18543 | reductions in green. |
| 18544 | Prefer high to wide: output the state number on a line of its own. |
| 18545 | |
| 18546 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18547 | |
| 18548 | * src/state.h, src/state.c (reductions_new): New. |
| 18549 | * src/LR0.c (set_state_table): Let all the states have a |
| 18550 | `reductions', even if reduced to 0. |
| 18551 | (save_reductions): Adjust. |
| 18552 | * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust. |
| 18553 | * src/print.c (print_reductions, print_actions): Adjust. |
| 18554 | * src/output.c (action_row): Adjust. |

| 18565 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18566 | |
| 18567 | * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL. |
| 18568 | |
| 18569 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18570 | |
| 18571 | * src/conflicts.c, src/conflicts.h (print_reductions): Move to... |
| 18572 | * src/print.c: here. |
| 18573 | (lookaheadset, shiftset): New, used as additional storage by |
| 18574 | print_reductions. |
| 18575 | (print_results): Adjust. |
| 18576 | (print_shifts, print_gotos, print_errs): New, extracted from... |
| 18577 | (print_actions): here. |
| 18578 | * src/print_graph.c (print_actions): Remove dead code. |
| 18579 | |
| 18580 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18581 | |
| 18582 | * src/reader.c (copy_dollar, copy_at): Better checking of `n' in |
| 18583 | `$n' and `@n'. |
| 18584 | |
| 18585 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18586 | |
| 18587 | * src/lalr.c (add_lookback_edge): Use state_t instead of ints. |
| 18588 | (build_relations): Adjust. |
| 18589 | |
| 18590 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18591 | |
| 18592 | * src/lalr.c (set_goto_map): Remove a wrong but benign loop |
| 18593 | duplication. |
| 18594 | |
| 18595 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18596 | |
| 18597 | * src/reader.c (packgram): Catch nitems overflows. |
| 18598 | |
| 18599 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18600 | |
| 18601 | * src/files.c, src/files.h (guard_obstack): Remove. |
| 18602 | * src/output.c (output): Adjust. |
| 18603 | * src/reader.c (parse_braces): New, factoring... |
| 18604 | (copy_action, copy_guard): these two which are renamed as... |
| 18605 | (parse_action, parse_guard): these. |
| 18606 | As a voluntary consequence, using braces around guards is now |
| 18607 | mandatory. |
| 18608 | |
| 18609 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18610 | |
| 18611 | * src/gram.h (rule_t): `guard' and `guard_line' are new members. |
| 18612 | * src/reader.c (symbol_list): `guard' and `guard_line' are new |
| 18613 | members. |
| 18614 | (symbol_list_new): Adjust. |
| 18615 | (copy_action): action_line is the first line, not the last. |
| 18616 | (copy_guard): Just as for actions, store the `action' only, not |
| 18617 | the switch/case/break flesh. |
| 18618 | Don't parse the user action that might follow the guard, let... |
| 18619 | (readgram): do it, i.e., now, there can be an action after a |
| 18620 | guard. |
| 18621 | In other words the guard is just explicitly optional. |
| 18622 | (packgram): Adjust. |
| 18623 | * src/output.c (guards_output): New. |
| 18624 | (output_parser): Call it when needed. |
| 18625 | (output): Also free the guard and attrs obstacks. |
| 18626 | * src/files.c, src/files.h (obstack_save): Remove. |
| 18627 | (output_files): Remove. |
| 18628 | As a result, if one needs the former `.act' file, using an |
| 18629 | appropriate skeleton which requires actions and guards is now |
| 18630 | required. |
| 18631 | * src/main.c (main): Adjust. |
| 18632 | * tests/semantic.at: New. |
| 18633 | * tests/regression.at: Use `input.y' as input file name. |
| 18634 | Avoid 8+3 problems by requiring input.c when the test needs the |
| 18635 | parser. |
| 18636 | |
| 18637 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18638 | |

| 18640 | fields. |
| 18641 | |
| 18642 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18643 | |
| 18644 | All the hacks using a final pseudo state are now useless. |
| 18645 | |
| 18646 | * src/LR0.c (set_state_table): state_table holds exactly nstates. |
| 18647 | * src/lalr.c (nLA): New. |
| 18648 | (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it |
| 18649 | instead of lookaheadsp from the pseudo state (nstate + 1). |
| 18650 | |
| 18651 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18652 | |
| 18653 | * src/output.c (action_row, token_actions): Use a state_t instead |
| 18654 | of a integer, and nlookaheads instead of the following state's |
| 18655 | lookaheadsp. |
| 18656 | |
| 18657 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18658 | |

| 18660 | (resolve_sr_conflict, set_conflicts, solve_conflicts) |
| 18661 | (count_sr_conflicts, count_rr_conflicts, conflicts_output) |
| 18662 | (conflicts_print, print_reductions): Use a state_t instead of an |
| 18663 | integer when referring to a state. |
| 18664 | As much as possible, depend upon nlookaheads, instead of the |
| 18665 | `lookaheadsp' member of the following state (since lookaheads of |
| 18666 | successive states are successive, the difference between state n + 1 |
| 18667 | and n served as the number of lookaheads for state n). |
| 18668 | * src/lalr.c (add_lookback_edge): Likewise. |
| 18669 | * src/print.c (print_core, print_actions, print_state) |
| 18670 | (print_results): Likewise. |

| 18678 | ANSIfy. |
| 18679 | Remove `register' indications. |
| 18680 | Add plenty of `static'. |
| 18681 | |
| 18682 | 2001-12-27 Akim Demaille <akim@epita.fr> |
| 18683 | |
| 18684 | * src/output.c (prepare): Drop the muscle `ntbase' which |
| 18685 | duplicates ntokens. |
| 18686 | * src/bison.simple: Formatting/comment changes. |
| 18687 | Use YYNTOKENS only, which is documented, but not YYNTBASE, which |
| 18688 | is an undocumented synonym. |
| 18689 | |
| 18690 | 2001-12-22 Akim Demaille <akim@epita.fr> |
| 18691 | |
| 18692 | * src/output.c (output_table_data): Change the prototype to use |
| 18693 | `int' for array ranges: some invocations do pass an int, not a |
| 18694 | short. |
| 18695 | Reported by Wayne Green. |

| 18699 | Some actions of web2c.y are improperly triggered. |
| 18700 | Reported by Mike Castle. |
| 18701 | |
| 18702 | * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/. |
| 18703 | * tests/regression.at (Web2c): Rename as... |
| 18704 | (Web2c Report): this. |

| 18718 | ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__)) |
| 18719 | Reported by Nelson Beebee. |
| 18720 | |
| 18721 | * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with |
| 18722 | `#define it_succeeded 0' and `assert (it_succeeded)'. |
| 18723 | |
| 18724 | 2001-12-17 Marc Autret <autret_m@epita.fr> |
| 18725 | |
| 18726 | * src/bison.simple: Don't hard code the skeleton line and filename. |
| 18727 | * src/output.c (output_parser): Rename 'line' as 'output_line'. |
| 18728 | New line counter 'skeleton_line' (skeleton-line muscle). |
| 18729 | |
| 18730 | 2001-12-17 Paul Eggert <eggert@twinsun.com> |
| 18731 | |
| 18732 | * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that |
| 18733 | YYDEBUG must be defined to a nonzero value. |
| 18734 | |
| 18735 | * src/bison.simple (yytname): Do not assume that the user defines |
| 18736 | YYDEBUG to a properly parenthesized expression. |
| 18737 | |
| 18738 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 18739 | |

| 18748 | |
| 18749 | * src/files.h, src/files.c (open_files, close_files): Remove. |

| 18765 | |
| 18766 | * src/output.c (output_obstack): Be static and rename as... |
| 18767 | (format_obstack): this, to avoid any confusion with files.c's |
| 18768 | output_obstack. |
| 18769 | * src/reader.h (muscle_obstack): Move to... |
| 18770 | * src/output.h: here, since it's defined in output.c. |
| 18771 | |
| 18772 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 18773 | |

| 18782 | 2001-12-17 Akim Demaille <akim@epita.fr> |
| 18783 | |
| 18784 | * src/files.c (output_files): Free the output_obstack. |
| 18785 | * src/main.c (main): Call print and print_graph conditionally. |
| 18786 | * src/print.c (print): Work unconditionally. |

| 18791 | |
| 18792 | * src/output.c (actions_output): Fix. When we use %no-lines, |
| 18793 | there is one less line per action. |
| 18794 | |
| 18795 | 2001-12-16 Marc Autret <autret_m@epita.fr> |
| 18796 | |
| 18797 | * src/bison.simple: Remove a useless #line directive. |
| 18798 | s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'. |
| 18799 | * src/output.c (get_lines_number): New. |
| 18800 | (output_parser): Adjust, now takes care about the lines of a |
| 18801 | output muscles. |
| 18802 | Fix line numbering. |
| 18803 | (actions_output): Computes the number of lines taken by actions. |
| 18804 | (output_master_parser): Insert new skeleton which is the name of |
| 18805 | the output parser file name. |
| 18806 | |
| 18807 | 2001-12-15 Marc Autret <autret_m@epita.fr> |

| 18815 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18816 | |
| 18817 | Make `make distcheck' work. |
| 18818 | |
| 18819 | * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses |
| 18820 | system.h which uses libgettext.h. |
| 18821 | |
| 18822 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18823 | |
| 18824 | * src/nullable.c (set_nullable): Useless rules must be skipped, |
| 18825 | otherwise, since we range over their symbols, we might look at a |
| 18826 | nonterminal which no longer ``exists'', i.e., it is not counted in |
| 18827 | `nvars', hence we overflow our arrays. |
| 18828 | |
| 18829 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18830 | |
| 18831 | The header can also be produced directly, without any obstack! |
| 18832 | Yahoo! |
| 18833 | |
| 18834 | * src/files.c, src/files.h (defines_obstack): Remove. |
| 18835 | (compute_header_macro): Global. |
| 18836 | (defines_obstack_save): Remove. |
| 18837 | * src/reader.c (parse_union_decl): No longer output to |
| 18838 | defines_obstack: its content can be found in the `stype' muscle |
| 18839 | anyway. |
| 18840 | (output_token_translations): Merge into... |
| 18841 | (symbols_output): this. |

| 18848 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18849 | |
| 18850 | * src/reader.c (parse_union_decl): Instead of handling two obstack |
| 18851 | simultaneously, use one to define the `stype' muscle, and use the |
| 18852 | value of the latter to fill defines_obstack. |
| 18853 | (copy_comment): Remove. |
| 18854 | (copy_comment2): Work for a single obstack. |

| 18860 | * src/lex.c, src/lex.h (xgetc): No longer static. |
| 18861 | * src/reader.c (parse_union_decl): Revamp. |
| 18862 | |
| 18863 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18864 | |
| 18865 | Still making progress in separating Bison into (i) input, (ii) |
| 18866 | process, (iii) output: now we can directly output the parser file |
| 18867 | without using table_obstack at all. |
| 18868 | |
| 18869 | * src/files.c, src/files.h (table_obstack): Bye bye. |
| 18870 | (parser_file_name): New. |
| 18871 | * src/files.c (compute_output_file_names): Compute it. |
| 18872 | * src/output.c (actions_output, output_parser) |
| 18873 | (output_master_parser): To a file instead of an obstack. |
| 18874 | |
| 18875 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18876 | |
| 18877 | Attach actions to rules, instead of pre-outputting them to |
| 18878 | actions_obstack. |
| 18879 | |
| 18880 | * src/gram.h (rule_t): action and action_line are new members. |
| 18881 | * src/reader.c (symbol_list): Likewise. |
| 18882 | (copy_action): Save the actions within the rule. |
| 18883 | (packgram): Save them in rule_table. |
| 18884 | * src/output.c (actions_output): New. |
| 18885 | (output_parser): Use it on `%%actions'. |
| 18886 | (output_rule_data): Don't free rule_table. |
| 18887 | (output): Do it. |
| 18888 | (prepare): Don't save the `action' muscle. |
| 18889 | * src/bison.simple: s/%%action/%%actions/. |
| 18890 | |
| 18891 | 2001-12-15 Akim Demaille <akim@epita.fr> |
| 18892 | |
| 18893 | * src/reader.c (copy_action): When --yacc, don't append a `;' |
| 18894 | to the user action: let it fail if lacking. |
| 18895 | Suggested by Arnold Robbins and Tom Tromey. |
| 18896 | |
| 18897 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 18898 | |
| 18899 | * src/lex.c (literalchar): Simply return the char you decoded, non |
| 18900 | longer mess around with obstacks and int pointers. |
| 18901 | Adjust all callers. |
| 18902 | |
| 18903 | 2001-12-14 Akim Demaille <akim@epita.fr> |
| 18904 | |
| 18905 | * src/lex.c (literalchar): Don't escape the special characters, |
| 18906 | just decode them, and keep them as char (before, eol was output as |
| 18907 | the 2 char string `\n' etc.). |
| 18908 | * src/output.c (output_rule_data): Use quotearg to output the |
| 18909 | token strings. |
| 18910 | |
| 18911 | 2001-12-13 Paul Eggert <eggert@twinsun.com> |
| 18912 | |
| 18913 | * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE): |
| 18914 | Do not infringe on the global user namespace when using C++. |
| 18915 | (YYFPRINTF, YYSTDERR): New macros, needed for the above. |
| 18916 | All uses of `fprintf' and `stderr' changed. |
| 18917 | |
| 18918 | * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR. |
| 18919 | |
| 18920 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 18921 | |
| 18922 | The computation of nullable is broken: it doesn't handle empty |
| 18923 | RHS's properly. |
| 18924 | |
| 18925 | * tests/torture.at (GNU AWK Grammar): New. |
| 18926 | * tests/sets.at (Nullable): New. |
| 18927 | * src/nullable.c (set_nullable): Instead of blindly looping over |
| 18928 | `ritems', loop over the rules, and then over their rhs's. |
| 18929 | |
| 18930 | Work around Autotest bugs. |
| 18931 | |
| 18932 | * src/warshall.c (bitmatrix_print): Don't use `+--+' as table |
| 18933 | frame, because Autotest understand lines starting with a `+' as |
| 18934 | traces from the shell. Then, they are not processed properly. |
| 18935 | Admittedly an Autotest bug, but we don't have time to wait for |
| 18936 | Autotest to catch up. |
| 18937 | * tests/regression.at (Broken Closure): Adjust to the new table |
| 18938 | frames. |
| 18939 | Move to... |
| 18940 | * tests/sets.at: here. |
| 18941 | |
| 18942 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 18943 | |
| 18944 | * src/closure.c (closure): Use nrules instead of playing tricks |
| 18945 | with BITS_PER_WORD. |
| 18946 | |
| 18947 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 18948 | |
| 18949 | * src/print.c (print_actions): Output the handling of `$' as the |
| 18950 | traces do: shifting the token EOF. Before EOF was treated as a |
| 18951 | nonterminal. |
| 18952 | * tests/regression.at: Adjust some tests. |
| 18953 | * src/print_graph.c (print_core): Complete the set of items via |
| 18954 | closure. The next-to-final and final states are still unsatisfying, |
| 18955 | but that's to be addressed elsewhere. |
| 18956 | No longer output the rule numbers, but do output the state number. |
| 18957 | A single loop for the shifts + gotos is enough, but picked a |
| 18958 | distinct color for each. |
| 18959 | (print_graph): Initialize and finalize closure. |
| 18960 | |
| 18961 | 2001-12-13 Akim Demaille <akim@epita.fr> |
| 18962 | |
| 18963 | * src/reader.c (readgram): Remove dead code, an strip useless |
| 18964 | braces. |
| 18965 | (get_type): Remove, unused. |
| 18966 | |
| 18967 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 18968 | |
| 18969 | * src/complain.h, src/complain.c: Remove error_one_per_line, rely |
| 18970 | on that of lib/error.c. |
| 18971 | |
| 18972 | 2001-12-12 Akim Demaille <akim@epita.fr> |
| 18973 | |
| 18974 | Some hosts don't like `/' in includes. |
| 18975 | |
| 18976 | * src/system.h: Include libgettext.h without qualifying the path. |
| 18977 | * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove |
| 18978 | $(top_srcdir). |
| 18979 | |
| 18980 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 18981 | |
| 18982 | * src/output.c (output_parser): Remove useless muscle. |
| 18983 | |
| 18984 | 2001-12-11 Marc Autret <autret_m@epita.fr> |
| 18985 | |
| 18986 | * src/bison.simple: Remove #line just before %%epilogue. It |
| 18987 | is now handled in ... |
| 18988 | * src/reader.c (read_additionnal_code): Add the output of a |
| 18989 | #line for the epilogue. |
| 18990 | |
| 18991 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 18992 | |
| 18993 | * src/reader.c (copy_definition): Re-use CPP-outed code which |
| 18994 | replace precedent remove. |
| 18995 | * src/bison.simple: Remove #line before %%prologue because |
| 18996 | %%input-line is wrong at this time. |
| 18997 | |
| 18998 | 2001-12-10 Marc Autret <autret_m@epita.fr> |
| 18999 | |
| 19000 | * src/reader.c (symbols_output): Clean up. |
| 19001 | * src/output.c (output_gram, output): Clean up. |
| 19002 | |
| 19003 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19004 | |
| 19005 | * src/lalr.c (initialize_lookaheads): New. Extracted from... |
| 19006 | * src/LR0.c (set_state_table): here. |
| 19007 | * src/lalr.c (lalr): Call it. |
| 19008 | |
| 19009 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19010 | |
| 19011 | * src/state.h (shifts): Remove the `number' member: shifts are |
| 19012 | attached to state, hence no longer need to be labelled with a |
| 19013 | state number. |
| 19014 | |
| 19015 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19016 | |
| 19017 | Now that states have a complete set of members, the linked list of |
| 19018 | shifts is useless: just fill directly the state's shifts member. |
| 19019 | |
| 19020 | * src/state.h (shifts): Remove the `next' member. |
| 19021 | * src/LR0.c (first_state, last_state): Remove. |
| 19022 | Adjust the callers. |
| 19023 | (augment_automaton): Don't look for the shifts that must be added |
| 19024 | a shift on EOF: it is those of the state we looked for! But now, |
| 19025 | since shifts are attached, it is no longer needed to looking |
| 19026 | merely by its id: its number. |
| 19027 | |
| 19028 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19029 | |
| 19030 | * src/LR0.c (augment_automaton): Better variable locality. |
| 19031 | Remove an impossible branch: if there is a state corresponding to |
| 19032 | the start symbol being shifted, then there is shift for the start |
| 19033 | symbol from the initial state. |
| 19034 | |
| 19035 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19036 | |
| 19037 | * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state' |
| 19038 | only when appropriate: when insert_start_shifting_state' is not |
| 19039 | invoked. |
| 19040 | * tests/regression.at (Rule Line Numbers): Adjust. |
| 19041 | |
| 19042 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19043 | |
| 19044 | * src/LR0.c (augment_automaton): Now that all states have shifts, |
| 19045 | merge the two cases addition shifts to the initial state. |
| 19046 | |
| 19047 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19048 | |
| 19049 | * src/lalr.c (set_state_table): Move to... |
| 19050 | * src/LR0.c: here. |
| 19051 | * src/lalr.c (lalr): Don't call it... |
| 19052 | * src/LR0.c (generate_states): do it. |
| 19053 | * src/LR0.h (first_state): Remove, only the table is used. |
| 19054 | |
| 19055 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19056 | |
| 19057 | * src/LR0.h (first_shift, first_reduction): Remove. |
| 19058 | * src/lalr.c: Don't use first_shift: find shifts through the |
| 19059 | states. |
| 19060 | |
| 19061 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19062 | |
| 19063 | * src/LR0.c: Attach shifts to states as soon as they are |
| 19064 | computed. |
| 19065 | * src/lalr.c (set_state_table): Instead of assigning shifts to |
| 19066 | state, just assert that the mapping was properly done. |
| 19067 | |
| 19068 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19069 | |
| 19070 | * src/LR0.c (insert_start_shift): Rename as... |
| 19071 | (insert_start_shifting_state): this. |
| 19072 | (insert_eof_shifting_state, insert_accepting_state): New. |
| 19073 | (augment_automaton): Adjust. |
| 19074 | Better locality of the variables. |
| 19075 | When looking if the start_symbol is shifted from the initial |
| 19076 | state, using `while (... symbol != start_symbol ...)' sounds |
| 19077 | better than `while (... symbol < start_symbol ...)': If fail |
| 19078 | to see how the order between symbols could be relevant! |
| 19079 | |
| 19080 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19081 | |
| 19082 | * src/getargs.h: Don't declare `spec_name_prefix' and |
| 19083 | `spec_file_prefix', declared by src/files.h. |
| 19084 | * src/files.c, src/files.h: Default for spec_name_prefix is "yy". |
| 19085 | * src/muscle_tab.c (muscle_init): Default prefix to NULL. |
| 19086 | * src/output.c (prepare): Adjust. |
| 19087 | * src/reader.c (symbols_output): Likewise. |
| 19088 | * src/vmsgetargs.c: Vaguely adjust, but who cares? |
| 19089 | |
| 19090 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19091 | |
| 19092 | * src/muscle_tab.c (muscle_init): NULL is a better default than |
| 19093 | `"0"'. |
| 19094 | |
| 19095 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19096 | |
| 19097 | * src/reader.c (reader): Calling symbols_output once is enough. |
| 19098 | |
| 19099 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19100 | |
| 19101 | Now that states have a complete set of members, the linked list of |
| 19102 | reductions is useless: just fill directly the state's reductions |
| 19103 | member. |
| 19104 | |
| 19105 | * src/state.h (struct reductions): Remove member `number' and |
| 19106 | `next'. |
| 19107 | * src/LR0.c (first_reduction, last_reduction): Remove. |
| 19108 | (save_reductions): Don't link the new reductions, store them in |
| 19109 | this_state. |
| 19110 | * src/lalr.c (set_state_table): No need to attach reductions to |
| 19111 | states, it's already done. |
| 19112 | * src/output.c (output_actions): No longer free the shifts, then |
| 19113 | the reductions, then the states: free all the states and their |
| 19114 | members. |
| 19115 | |
| 19116 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19117 | |
| 19118 | * src/options.c (OPTN, DRTV, BOTH): New. |
| 19119 | (option_table): Use them. |
| 19120 | |
| 19121 | * src/muscle_tab.c: Don't include xalloc.h and string.h: that's |
| 19122 | the job of system.h. |
| 19123 | * src/options.c: Don't include stdio.h and xalloc.h for the same |
| 19124 | reasons. |
| 19125 | |
| 19126 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19127 | |
| 19128 | * src/output.c (output, prepare): Make sure the values of the |
| 19129 | muscles `action' and `prologue' are 0-terminated. |
| 19130 | |
| 19131 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19132 | |
| 19133 | Clean up GCC warnings. |
| 19134 | |
| 19135 | * src/reader.c (copy_action): `buf' is not used. |
| 19136 | (parse_skel_decl): Be static. |
| 19137 | * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'. |
| 19138 | * src/options.h (create_long_option_table): Have a real prototype. |
| 19139 | * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete) |
| 19140 | (hash_delete_at): Return const void *. |
| 19141 | Adjust casts to preserve the const. |
| 19142 | |
| 19143 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19144 | |
| 19145 | * configure.in: Require 2.52g. |
| 19146 | M4 is not needed, but AUTOM4TE is. |
| 19147 | * m4/m4.m4: Remove. |
| 19148 | * tests/Makefile.am: Adjust. |
| 19149 | |
| 19150 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19151 | |
| 19152 | One structure for states is enough, even though theoretically |
| 19153 | there are LR(0) states and LALR(1) states. |
| 19154 | |
| 19155 | * src/lalr.h (state_t): Remove. |
| 19156 | (state_table): Be state_t **, not state_t *. |
| 19157 | * src/state.h (core, CORE_ALLOC): Rename as... |
| 19158 | (state_t, STATE_ALLOC): this. |
| 19159 | Add the LALR(1) members: shifts, reductions, errs. |
| 19160 | * src/LR0.c (state_table): Rename as... |
| 19161 | (state_hash): this, to avoid name clashes with the global |
| 19162 | `state_table'. |
| 19163 | * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c |
| 19164 | * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust. |
| 19165 | |
| 19166 | 2001-12-10 Akim Demaille <akim@epita.fr> |
| 19167 | |
| 19168 | Bison dumps core on bash.y. |
| 19169 | Reported by Pascal Bart. |
| 19170 | |
| 19171 | * src/warshall.c (bitmatrix_print): New. |
| 19172 | (TC): Use it. |
| 19173 | When performing a transitive closure R(i, j) && R(j, k) => R(i, k), |
| 19174 | j must be the outer loop. |
| 19175 | * tests/regression.at (Broken Closure): New. |
| 19176 | |
| 19177 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19178 | |
| 19179 | * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and |
| 19180 | its argument. |
| 19181 | Reported by Peter Hamorsky. |
| 19182 | |
| 19183 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19184 | |
| 19185 | * src/conflicts.c (err_table): Remove. |
| 19186 | (resolve_sr_conflict): Adjust. |
| 19187 | * src/lalr.h (state_t.reduction_table, state_t.shift_table): |
| 19188 | Rename as... |
| 19189 | (state_t.reductions, state_t.shifts): this. |
| 19190 | |
| 19191 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19192 | |
| 19193 | * src/reduce.c (reduce_grammar_tables): No longer disable the |
| 19194 | removal of useless rules via CPP but via `if (0)', so that the |
| 19195 | compiler still check the code is valid. |
| 19196 | For instance, it should have noticed `rline' no longer exists: use |
| 19197 | the `line' member of rule_t. |
| 19198 | * src/gram.c (dummy, rline): Remove, unused. |
| 19199 | |
| 19200 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19201 | |
| 19202 | * src/output.c (pack_vector): Use assert, not berror. |
| 19203 | * src/main.c (berror): Remove, unused. |
| 19204 | |
| 19205 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19206 | |
| 19207 | New experimental feature: if --verbose --trace output all the |
| 19208 | items of a state, not only its kernel. |
| 19209 | |
| 19210 | * src/print.c (print_core): If `trace_flag', then invoke closure |
| 19211 | before outputting the items of the state (print_core is no longer |
| 19212 | a correct name them). |
| 19213 | (print_results): Invoke new_closure/free_closure if needed. |
| 19214 | |
| 19215 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19216 | |
| 19217 | * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount. |
| 19218 | * src/closure.c, src/closure.h (itemsetsize): Rename as... |
| 19219 | (nitemset): for consistency with the rest of the project. |
| 19220 | |
| 19221 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19222 | |
| 19223 | * src/closure.c (print_closure): Improve. |
| 19224 | (closure): Use it for printing input and output. |
| 19225 | |
| 19226 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19227 | |
| 19228 | * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are |

| 19253 | locality, BITISSET, RESETBIT etc. |
| 19254 | |
| 19255 | 2001-12-05 Akim Demaille <akim@epita.fr> |

| 19266 | |
| 19267 | * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New. |
| 19268 | * src/conflicts.c: Use it. |
| 19269 | Restore a few missing `if (!SHIFT_IS_DISABLED)' which were |
| 19270 | incorrectly ``simplified''. |

| 19332 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19333 | |
| 19334 | * src/lalr.c (transpose): Free the memory allocated to the |
| 19335 | argument, as it is replaced by the results by the unique caller. |
| 19336 | (build_relations): Merely invoke transpose: it handles the memory |
| 19337 | deallocation. |
| 19338 | Improve variable locality. |
| 19339 | Avoid variables used as mere abbreviations. |
| 19340 | (compute_lookaheads): Use arrays instead of pointers. |
| 19341 | |
| 19342 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19343 | |

| 19348 | |
| 19349 | * src/derives.c (print_derives): Display the ruleno. |
| 19350 | * src/lalr.c (initialize_F, transpose): Better variable locality |
| 19351 | to improve readability. |
| 19352 | Avoid variables used as mere abbreviations. |
| 19353 | |
| 19354 | 2001-12-05 Akim Demaille <akim@epita.fr> |

| 19359 | |
| 19360 | * src/nullable.c (set_nullable): Use a for loop to de-obfuscate |
| 19361 | the handling of squeue. |
| 19362 | `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. |
| 19363 | |
| 19364 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19365 | |
| 19366 | Because useless nonterminals are now kept alive (instead of being |
| 19367 | `destroyed'), we now sometimes examine them, and store information |
| 19368 | related to them. Hence we need to know their number, and adjust |
| 19369 | memory allocations. |
| 19370 | |
| 19371 | * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer |
| 19372 | static. |
| 19373 | * src/LR0.c (allocate_itemsets): The memory allocated to |
| 19374 | `symbol_count' was used for two different purpose: once to count |
| 19375 | the number of occurrences of each symbol, and later reassigned to |
| 19376 | `shift_symbol', containing the symbol that can be shifted from a |
| 19377 | given state. |
| 19378 | Deobfuscate, i.e., allocate, use and free `symbol_count' here |
| 19379 | only, and... |
| 19380 | (new_itemsets): Allocate `shift_symbol' here. |
| 19381 | (allocate_itemsets): symbol_count includes useless nonterminals. |
| 19382 | Make room for them. |
| 19383 | (free_storage): Use `free', not `XFREE', for pointers that cannot |
| 19384 | be null. |
| 19385 | |
| 19386 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19387 | |
| 19388 | * src/nullable.c (set_nullable): Deobfuscate the handling of |
| 19389 | ritem. |
| 19390 | `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'. |
| 19391 | |
| 19392 | 2001-12-05 Akim Demaille <akim@epita.fr> |
| 19393 | |
| 19394 | * src/gram.c, src/gram.h (ritem_print): New. |
| 19395 | * src/gram.c (dummy): Remove, now there is actual code in gram.c. |
| 19396 | (This useless function was defined only to work around VMS linkers |
| 19397 | that can't handle compilation units with variables only). |
| 19398 | * src/reduce.c (dump_grammar): Use it to trace the construction of |
| 19399 | ritem. |
| 19400 | |
| 19401 | 2001-12-04 Paul Eggert <eggert@twinsun.com> |
| 19402 | |
| 19403 | * src/bison.simple (union yyalloc): Change member names |
| 19404 | to be the same as the stack names. |
| 19405 | (yyparse): yyptr is now union yyalloc *, not char *. |
| 19406 | (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning, |
| 19407 | and may generate better code on some machines. |
| 19408 | (yystpcpy): Use prototype if __STDC__ is defined, not just |
| 19409 | if __cplusplus is defined. |
| 19410 | |
| 19411 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19412 | |
| 19413 | * configure.in (WARNING_CFLAGS): Add -Werror when possible. |
| 19414 | (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU |
| 19415 | Gettext doesn't compile cleanly, and dies with -Werror. |
| 19416 | * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS): |
| 19417 | Include WARNING_CFLAGS here. |
| 19418 | * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared |
| 19419 | before being defined. |
| 19420 | |
| 19421 | 2001-11-27 Paul Eggert <eggert@twinsun.com> |
| 19422 | |
| 19423 | * lib/quotearg.h (quotearg_n, quotearg_n_style): |
| 19424 | First arg is int, not unsigned. |
| 19425 | * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise. |
| 19426 | (SIZE_MAX, UINT_MAX): New macros. |
| 19427 | (quotearg_n_options): Abort if N is negative. |
| 19428 | Avoid overflow check on hosts where size_t is 64 bits and int |
| 19429 | is 32 bits, as overflow is impossible there. |
| 19430 | Fix off-by-one typo that caused unnecessary reallocation. |
| 19431 | |
| 19432 | 2001-11-29 Paul Eggert <eggert@twinsun.com> |
| 19433 | |
| 19434 | Name space cleanup in generated parser. |
| 19435 | |
| 19436 | * doc/bison.texinfo (Bison Parser): Discuss system headers |
| 19437 | and their effect on the user name space. |
| 19438 | |
| 19439 | * src/bison.simple: |
| 19440 | (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX, |
| 19441 | YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary, |
| 19442 | i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE). |
| 19443 | |
| 19444 | (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing |
| 19445 | on user names when possible. |
| 19446 | |
| 19447 | (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn. |
| 19448 | Simplify test for whather <alloca.h> exists. |
| 19449 | |
| 19450 | (<stdlib.h>): Include if we will use malloc, and if standard C or C++. |
| 19451 | |
| 19452 | (<stdio.h>): Include if YYDEBUG. |
| 19453 | |
| 19454 | (yymemcpy): Renamed from __yy_memcpy. Do not define unless |
| 19455 | ! defined (yyoverflow) && ! defined (yymemcpy). |
| 19456 | |
| 19457 | (yymemcpy, yyparse): Rename local variables as needed so that |
| 19458 | they all begin with 'yy'. |
| 19459 | |
| 19460 | (yystrlen, yystpcpy): New functions. |
| 19461 | |
| 19462 | (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES. |
| 19463 | All uses changed. |
| 19464 | |
| 19465 | (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy |
| 19466 | instead of relying on string.h functions. Use YYSTACK_ALLOC |
| 19467 | and YYSTACK_FREE instead of malloc and free. |
| 19468 | |
| 19469 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19470 | |
| 19471 | * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions |
| 19472 | before their first uses. |
| 19473 | (YYBISON, YYPURE): Move to the top of the output. |
| 19474 | |
| 19475 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19476 | |

| 19480 | |
| 19481 | * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty |
| 19482 | if body instead of `;' to pacify GCC's warnings. |
| 19483 | |
| 19484 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19485 | |
| 19486 | Instead of mapping the LHS of unused rules to -1, keep the LHS |
| 19487 | valid, but flag the rules as invalid. |
| 19488 | |
| 19489 | * src/gram.h (rule_t): `useful' is a new member. |
| 19490 | * src/print.c (print_grammar): Adjust. |

| 19496 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19497 | |
| 19498 | * src/reduce.c (reduce_output): Formatting changes. |
| 19499 | * src/print.c (print_results, print_grammar): Likewise. |
| 19500 | * tests/regression.at (Rule Line Numbers) |

| 19503 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19504 | |
| 19505 | * src/reduce.c (nonterminals_reduce): Instead of throwing away |
| 19506 | useless nonterminals, move them at the end of the symbol arrays. |
| 19507 | (reduce_output): Adjust. |
| 19508 | * tests/reduce.at (Useless Nonterminals): Adjust. |
| 19509 | |
| 19510 | 2001-11-30 Akim Demaille <akim@epita.fr> |
| 19511 | |
| 19512 | * src/reduce.c: Various comment/formatting changes. |
| 19513 | (nonterminals_reduce): New, extracted from... |
| 19514 | (reduce_grammar_tables): here. |
| 19515 | (reduce_grammar): Call nonterminals_reduce. |
| 19516 | |

| 19520 | (YYSTACK_ALLOC): Resurrect this macro, with its old meaning. |
| 19521 | (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE): |
| 19522 | New macros. |
| 19523 | (union yyalloc): New type. |
| 19524 | (__yy_memcpy): Last arg is size_t, not unsigned int, to remove |
| 19525 | an arbitrary restriction on hosts where size_t is wider than int. |
| 19526 | |
| 19527 | (yyparse): Don't dump core if alloca or malloc fails; instead, report |
| 19528 | a parser stack overflow. Allocate just one block of memory for all |
| 19529 | three stacks, instead of allocating three blocks; this typically is |
| 19530 | faster and reduces fragmentation. |
| 19531 | |
| 19532 | Do not limit the number of items in the stack to a value that fits |
| 19533 | in 'int', as this is an arbitrary limit on hosts with 64-bit |
| 19534 | size_t and 32-bit int. |
| 19535 | |
| 19536 | 2001-11-29 Marc Autret <autret_m@epita.fr> |
| 19537 | |
| 19538 | * tests/calc.at [AT_DATA_CALC_Y]: Use %error-verbose instead |
| 19539 | of defining YYERROR_VERBOSE. |
| 19540 | [AT_DATA]: $4 is now out of C declarations in the prologue. |

| 19542 | 2001-11-28 Marc Autret <autret_m@epita.fr> |
| 19543 | |
| 19544 | * src/reader.c (parse_dquoted_param): New. |
| 19545 | (parse_skel_decl): Use it. |
| 19546 | * src/lex.h: Add its prototype. |
| 19547 | * src/lex.c (literalchar): Become not static. |
| 19548 | |
| 19549 | 2001-11-28 Marc Autret <autret_m@epita.fr> |

| 19553 | (prepare): Echo name modification. |
| 19554 | * src/getargs.h: Clean its extern declaration. |
| 19555 | * src/getargs.c (error_verbose_flag): Remove. |
| 19556 | (getargs): Remove case 'e'. |
| 19557 | * src/options.c (option_table): 'error-verbose' is now seen as simple |
| 19558 | percent option. |
| 19559 | Include output.h. |
| 19560 | |
| 19561 | * src/reader.c (read_declarations): Remove case tok_include. |
| 19562 | (parse_include_decl): Remove. |

| 19565 | option. |
| 19566 | |
| 19567 | 2001-11-28 Marc Autret <autret_m@epita.fr> |
| 19568 | |
| 19569 | * src/bison.simple: Adjust muscle names. |
| 19570 | * src/muscle_tab.c (muscle_init): Also rename the muscles. |
| 19571 | * src/output.c (prepare): s/_/-/ for the muscles names. |
| 19572 | (output_parser): When scanning for a muscle, allow '-' instead of '_'. |
| 19573 | |
| 19574 | 2001-11-28 Marc Autret <autret_m@epita.fr> |
| 19575 | |
| 19576 | * src/bison.simple: Fix debug. |

| 19584 | 2001-11-28 Akim Demaille <akim@epita.fr> |
| 19585 | |
| 19586 | * src/closure.c (closure): `b' and `ruleno' denote the same value: |
| 19587 | keep ruleno only. |
| 19588 | |
| 19589 | 2001-11-28 Akim Demaille <akim@epita.fr> |
| 19590 | |
| 19591 | * src/closure.c (closure): Instead of looping over word in array |
| 19592 | then bits in words, loop over bits in array. |
| 19593 | |
| 19594 | 2001-11-28 Akim Demaille <akim@epita.fr> |
| 19595 | |
| 19596 | * src/closure.c (closure): No longer optimize the special case |
| 19597 | where all the bits of `ruleset[r]' are set to 0, to make the code |
| 19598 | clearer. |
| 19599 | |
| 19600 | 2001-11-28 Akim Demaille <akim@epita.fr> |

| 21332 | |
| 21333 | * src/reader.c (gensym): `gensym_count' is your own. |

| 21349 | issues in Bison, it would mean way too much duplicate effort to |
| 21350 | import in Bison features implemented in 2.49c since 2.13. |
| 21351 | AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above. |

| 21384 | Since we now use obstacks, more % directives can be enabled. |
| 21385 | |
| 21386 | * src/lex.c (percent_table): Also accept `%yacc', |
| 21387 | `%fixed_output_files', `%defines', `%no_parser', `%verbose', and |
| 21388 | `%debug'. |
| 21389 | Handle the actions for `%semantic_parser' and `%pure_parser' here, |
| 21390 | instead of returning a token. |
| 21391 | * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused. |
| 21392 | * src/reader.c (read_declarations): Adjust. |
| 21393 | * src/files.c (open_files): Don't call `compute_base_names', don't |
| 21394 | compute `attrsfile' since they depend upon data which might be |
| 21395 | *in* the input file now. |
| 21396 | (output_files): Do it here. |
| 21397 | * src/output.c (output_headers): Document the fact that this patch |
| 21398 | introduces a guaranteed SEGV for semantic parsers. |

| 21425 | 2000-12-20 Akim Demaille <akim@epita.fr> |
| 21426 | |
| 21427 | * src/files.c (open_files): Actually the `.output' file is based |

| 21429 | * tests/suite.at (Checking output file names): Adjust. |
| 21430 | |
| 21431 | 2000-12-20 Akim Demaille <akim@epita.fr> |

| 21435 | * src/Makefile.am: Use pkgdata instead of data. |
| 21436 | |
| 21437 | 2000-12-20 Akim Demaille <akim@epita.fr> |

| 21462 | * tests/suite.at (Checking output file names): New test. |

| 21482 | Let the handling of the skeleton files be local to the procedures |
| 21483 | that use it. |
| 21484 | |
| 21485 | * src/files.c (xfopen, xfclose, skeleton_find, guardfile): No |

| 21494 | |
| 21495 | 2000-12-19 Akim Demaille <akim@epita.fr> |
| 21496 | |

| 21500 | 2000-12-19 Akim Demaille <akim@epita.fr> |
| 21501 | |
| 21502 | * src/files.c (open_files): Yipee! We no longer need all the code |
| 21503 | looking for `/tmp' since we have no tmp file. |
| 21504 | |
| 21505 | 2000-12-19 Akim Demaille <akim@epita.fr> |
| 21506 | |
| 21507 | * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C): |
| 21508 | New macros. |
| 21509 | * src/files.c (open_files): Less dependency on MSDOS etc. |
| 21510 | |
| 21511 | 2000-12-14 Akim Demaille <akim@epita.fr> |
| 21512 | |
| 21513 | * src/bison.s1 (YYLLOC_DEFAULT): New macro. |
| 21514 | Provide a default definition. |
| 21515 | Use it when executing the default @ action. |
| 21516 | * src/reader.c (reader_output_yylsp): No longer include |
| 21517 | `timestamp' and `text' in the default YYLTYPE. |
| 21518 | |
| 21519 | 2000-12-12 Akim Demaille <akim@epita.fr> |
| 21520 | |
| 21521 | * src/reader.c (copy_definition, parse_union_decl, copy_action) |

| 21533 | |
| 21534 | * lib/obstack.h: Formatting changes. |
| 21535 | (obstack_grow, obstack_grow0): Don't cast WHERE at all: it |
| 21536 | prevents type checking. |
| 21537 | (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't |
| 21538 | cast the value to (void *): assigning a `foo *' to a `void *' |
| 21539 | variable is valid. |
| 21540 | (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int. |
| 21541 | * src/reader.c (parse_union_decl): Typo: use obstack_1grow to |

| 21556 | 2000-11-17 Akim Demaille <akim@epita.fr> |
| 21557 | |
| 21558 | * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New |

| 21573 | * src/reader.c (reader): #define YYLSP_NEEDED to 1 instead of just |
| 21574 | defining. |

| 21576 | |
| 21577 | 2000-11-07 Akim Demaille <akim@epita.fr> |
| 21578 | |

| 21580 | Merge in a single CPP if/else. |

| 21587 | Qualify it `const'. |
| 21588 | (obstack_copy, obstack_copy0): Rename the second argument as |
| 21589 | `address' for consistency. Qualify it `const'. |
| 21590 | * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow) |
| 21591 | (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify |

| 21599 | Adjust dependencies. |
| 21600 | |
| 21601 | 2000-11-03 Akim Demaille <akim@epita.fr> |
| 21602 | |
| 21603 | For some reason, this was not applied. |

| 21617 | * src/files.c (obstack_save): New function. |
| 21618 | (done): Rename as... |
| 21619 | (output_files): this. |
| 21620 | Use `obstack_save'. |
| 21621 | * src/main.c (main): Don't use `atexit' to register `done', since |
| 21622 | it no longer has to remove tmp files, just call `output_files' |
| 21623 | when there are no errors. |
| 21624 | |
| 21625 | 2000-11-02 Akim Demaille <akim@epita.fr> |

| 21657 | |

| 21670 | 2000-10-16 Akim Demaille <akim@epita.fr> |
| 21671 | |

| 21729 | When a literal string is used to define two different tokens, |

| 21731 | Reported by Piotr Gackiewicz, and fixed by Neil Booth. |
| 21732 | |
| 21733 | * tests/regression.m4: New file. |
| 21734 | Include the core of the sample provided by Piotr Gackiewicz. |

| 21736 | properly. |

| 21738 | 2000-10-04 Akim Demaille <akim@epita.fr> |
| 21739 | |
| 21740 | * src/reader.c (parse_expect_decl): Keep `count' within the size |

| 21743 | |
| 21744 | 2000-10-02 Paul Eggert <eggert@twinsun.com> |
| 21745 | |
| 21746 | * bison.s1 (yyparse): Assign the default value |
| 21747 | unconditionally, to avoid a GCC warning and make the parser a |
| 21748 | tad smaller. |
| 21749 | |
| 21750 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21751 | |
| 21752 | * src/getargs.c (getargs): Don't dump `--help' on unrecognized |
| 21753 | options. |

| 21755 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21756 | |
| 21757 | * src/derives.c, src/print.c, src/reduce.c: To ease the |
| 21758 | translation, move some `\n' out of the translated strings. |
| 21759 | |
| 21760 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21761 | |
| 21762 | The location tracking mechanism is precious for parse error |
| 21763 | messages. Nevertheless, it is enabled only when `@n' is used in |
| 21764 | the grammar, which is a different issue (you can use it in error |
| 21765 | message, but not in the grammar per se). Therefore, there should |
| 21766 | be another means to enable it. |
| 21767 | |
| 21768 | * src/getargs.c (getargs): Support `--locations'. |
| 21769 | (usage): Report it. |
| 21770 | * src/getargs.h (locationsflag): Export it. |
| 21771 | * src/lex.c (percent_table): Support `%locations'. |
| 21772 | * src/reader.c (yylsp_needed): Remove this variable, now replaced |
| 21773 | with `locationsflag'. |
| 21774 | * doc/bison.texinfo: Document `--locations' and `%locations'. |
| 21775 | Sort the options. |
| 21776 | * tests/calc.m4: Test it. |
| 21777 | |
| 21778 | For regularity of the names, replace each |
| 21779 | (nolineflag, toknumflag, rawtokenumflag, noparserflag): with... |
| 21780 | (no_lineflag, token_tableflag, rawflag, no_parserflag): this. |
| 21781 | In addition replace each `flag' with `_flag'. |
| 21782 | |
| 21783 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21784 | |
| 21785 | Also test parse error messages, including with YYERROR_VERBOSE. |
| 21786 | |
| 21787 | * tests/calc.m4 (calc.y): Add support for `exp = exp' (non |
| 21788 | associative). |
| 21789 | Use it to check the computations. |
| 21790 | Use it to check `nonassoc' is honored. |
| 21791 | (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed |
| 21792 | `--yyerror-verbose'. |
| 21793 | (_AT_CHECK_CALC): Adjust to this option. |
| 21794 | (_AT_CHECK_CALC_ERROR): New macro to check parse error messages. |
| 21795 | |
| 21796 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21797 | |
| 21798 | Test also `--verbose', `--defines' and `--name-prefix'. Testing |
| 21799 | the latter demonstrates a flaw in the handling of non debugging |
| 21800 | parsers introduced by myself on 2000-03-16: `#define yydebug 0' |
| 21801 | was used in order to simplify: |
| 21802 | |
| 21803 | #if YYDEBUG |
| 21804 | if (yydebug) |
| 21805 | { |
| 21806 | ... |
| 21807 | } |
| 21808 | #endif |
| 21809 | |
| 21810 | into |
| 21811 | |
| 21812 | if (yydebug) |
| 21813 | { |
| 21814 | ... |
| 21815 | } |
| 21816 | |
| 21817 | unfortunately this leads to a CPP conflict when |
| 21818 | `--name-prefix=foo' is used since it produces `#define yydebug |
| 21819 | foodebug'. |
| 21820 | |
| 21821 | * src/bison.s1 [!YYDEBUG]: Do not define yydebug. |
| 21822 | (YYDPRINTF): New macro. |
| 21823 | Spread its use. |
| 21824 | * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from |
| 21825 | the bison options. |
| 21826 | Also test `--verbose', `--defines' and `--name-prefix'. |
| 21827 | |
| 21828 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21829 | |
| 21830 | Improve the readability of the produced parsers. |
| 21831 | |
| 21832 | * src/bison.s1: Formatting changes. |
| 21833 | Improve the comment related to the `$' mark. |
| 21834 | (yydefault): Don't fall through to `yyresume': `goto' there. |
| 21835 | * src/output.c (output_parser): When the `$' is met, skip the end |
| 21836 | of its line. |
| 21837 | New variable, `number_of_dollar_signs', to check there's exactly |
| 21838 | one `$' in the parser skeleton. |
| 21839 | |
| 21840 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21841 | |
| 21842 | * lib/xstrdup.c: New file, from the fileutils. |
| 21843 | * src/reader.c (parse_token_decl, get_type_name, parse_type_decl) |
| 21844 | (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup' |
| 21845 | instead of strlen + xmalloc + strcpy. |

| 21869 | Use the more standard files `xalloc.h' and `xmalloc.c' instead of |
| 21870 | Bison's `allocate.c' and `alloc.h'. This patch was surprisingly |
| 21871 | difficult and introduced a lot of core dump. It turns out that |
| 21872 | Bison used an implementation of `xmalloc' based on `calloc', and |
| 21873 | at various places it does depend upon the initialization to 0. I |
| 21874 | have not tried to isolate the pertinent places, and all the former |
| 21875 | calls to Bison's `xmalloc' are now using `XCALLOC'. Someday, |
| 21876 | someone should address this issue. |
| 21877 | |
| 21878 | * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove. |
| 21879 | * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New |

| 21973 | * src/output.c (token_actions): Introduce a temporary array, |
| 21974 | YYDEFACT, that makes it possible for this function to use |
| 21975 | output_short_table. |
| 21976 | |
| 21977 | 2000-10-02 Akim Demaille <akim@epita.fr> |
| 21978 | |
| 21979 | `user_toknums' is output as a `short[]' in `output.c', while it is |
| 21980 | defined as a `int[]' in `reader.c'. For consistency with the |

| 22026 | Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the |
| 22027 | purpose of config.h. system.h must not try to fix wrong |
| 22028 | definitions in config.h. |

| 22237 | |
| 22238 | 2000-03-17 Akim Demaille <akim@epita.fr> |
| 22239 | |
| 22240 | * src/reader.c (copy_string): New function, factored out from: |

| 22242 | (copy_guard): Likewise. |
| 22243 | |
| 22244 | 2000-03-17 Akim Demaille <akim@epita.fr> |
| 22245 | |
| 22246 | Change the handling of @s so that they behave exactly like $s. |
| 22247 | There is now a pseudo variable @$ (readble and writable), location |
| 22248 | of the lhs of the rule (by default ranging from the location of |
| 22249 | the first symbol of the rhs, to the location of the last symbol, |
| 22250 | or, if the rhs is empty, YYLLOC). |
| 22251 | |
| 22252 | * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of |
| 22253 | yyval. |
| 22254 | (yyparse): When providing a default semantic action, provide a |
| 22255 | default location action. |
| 22256 | (after the $): No longer change `*YYLSP', just stack YYLOC the |
| 22257 | same way you stack YYVAL. |
| 22258 | * src/reader.c (read_declarations): Use warns. |
| 22259 | (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'. |
| 22260 | (copy_action, case '@'): Likewise. |
| 22261 | Use a standard error message, to save useless work from |
| 22262 | translators. |
| 22263 | |
| 22264 | 2000-03-17 Akim Demaille <akim@epita.fr> |

| 22283 | |
| 22284 | * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to |
| 22285 | remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough. |
| 22286 | One `#if YYDEBUG' remains, since it uses variables which are |
| 22287 | defined only if `YYDEBUG != 0'. |
| 22288 | |
| 22289 | 2000-03-16 Akim Demaille <akim@epita.fr> |

| 22313 | handled via src/Makefile.am. |
| 22314 | (VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS, |
| 22315 | HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by |

| 22322 | (DEFS): Propagate the location of bison library files and of the |
| 22323 | locale files. |
| 22324 | (INCLUDES): Added `-I ..' so that one can compile with srcdir != |
| 22325 | builddir. |
| 22326 | * acinclude.m4: Remove, replaced by the directory m4. |
| 22327 | * m4/Makefile.am (EXTRA_DIST): New variable. |
| 22328 | * m4/gettext.m4: New file, from the fileutils. |
| 22329 | * m4/lcmessage.m4: Likewise |
| 22330 | * m4/progtest.m4: Likewise. |
