216
217 2008-11-07 Akim Demaille <demaille@gostai.com>
218
219 Add "%define assert" to variants.
220 This is used to help the user catch cases where some value gets
221 ovewritten by a new one. This should not happen, as this will
222 probably leak.
223
224 Unfortunately this uncovered a bug in the C++ parser itself: the
225 lookahead value was not destroyed between two calls to yylex. For
226 instance if the previous lookahead was a std::string, and then an int,
227 then the value of the std::string was correctly taken (i.e., the
228 lookahead was now an empty string), but std::string structure itself
229 was not reclaimed.
230
231 This is now done in variant::build(other&) (which is used to take the
232 value of the lookahead): other is not only stolen from its value, it
233 is also destroyed. This incurs a new performance penalty of a few
234 percent, and union becomes faster again.
235
236 * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
237 (b4_variant_if): New.
238 (variant::built): New.
239 Use it whereever the status of the variant changes.
240 * etc/bench.pl.in: Check the penalty of %define assert.
241
242 2008-11-07 Akim Demaille <demaille@gostai.com>
243
244 Use "%define variant" in bench.pl.
245 * etc/bench.pl.in: No longer use the pseudo directive %variants,
246 just use %define variants.
247
248 2008-11-07 Akim Demaille <demaille@gostai.com>
249
250 Regen.
251 * src/parse-gram.h, src/parse-gram.c: Regen.
252
253 2008-11-04 Joel E. Denny <jdenny@ces.clemson.edu>

508 2008-11-03 Akim Demaille <demaille@gostai.com>
509
510 Add documentation to bench.pl.
511 * etc/bench.pl.in: Comment changes.
512
513 2008-11-03 Akim Demaille <demaille@gostai.com>
514
515 Fuse the three stacks into a single one.
516 In order to make it easy to perform benchmarks to ensure that there are no
517 performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
518 lalr1-fusion.cc will replace lalr1.cc.
519
520 Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
521 test suite, the user must install a symbolic link from lalr1.cc to it.
522
523 Instead of having three stacks (state, value, location), use a stack
524 of triples. This considerably simplifies the code (and it will be
525 easier not to require locations as currently does the C++ parser),
526 and also gives a 10% speedup according to etc/bench (probably mainly since
527 memory allocation is done once instead of three times).
528
529 Another motivation is to make it easier to destruct properly
530 semantic values: now that they are bound to their state (hence
531 symbol type) it will be easier to call the appropriate destructor.
532
533 These changes should probably benefit the C parser too.
534
535 * data/lalr1.cc: Copy as... * data/lalr1-fusion.cc: this new
536 file.
537 (b4_rhs_value, b4_rhs_location): New definitions overriding those
538 from c++.m4.
539 (state_stack_type, semantic_stack_type, location_stack_type)
540 (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
541 (data_type, stack_type, yystack_): New.
542 (YYLLOC_DEFAULT, yypush_): Adjust.
543 (yyerror_range): Now based on data_type, not location_type.
544
545 2008-11-03 Akim Demaille <demaille@gostai.com>
546
547 Push the state, value, and location at the same time.
548 This is needed to prepare a forthcoming patch that fuses the three
549 stacks into one.
550
551 * data/lalr1.cc (parser::yypush_): New.
552 (parser::yynewstate): Change the semantics: instead of arriving to
553 this label when value and location have been pushed, but yystate
554 is to be pushed on the state stack, now the three of them must
555 have been pushed before. yystate still must be the new state.
556 This allows to use yypush_ everywhere instead of individual
557 handling of the stacks.
558
559 2008-11-03 Akim Demaille <demaille@gostai.com>
560
561 Prefer references to pointers.
562 * data/lalr1.cc (b4_symbol_actions): New, overrides the default C
563 definition to use references instead of pointers.
564 (yy_symbol_value_print_, yy_symbol_print_, yydestruct_):
565 Take the value and location as references.
566 Adjust callers.
567
568 2008-11-03 Akim Demaille <demaille@gostai.com>
569
570 stack::size instead of stack::height.
571 * data/lalr1.cc (stack::height): Rename as...
572 (stack::size): this.
573 Fix the output type.
574 Comment changes.
575
576 2008-11-03 Akim Demaille <demaille@gostai.com>
577
578 Use variants to support objects as semantic values.
579 This patch was inspired by work by Michiel De Wilde. But he used Boost
580 variants which (i) requires Boost on the user side, (ii) is slow, and
581 (iii) has useless overhead (the parser knows the type of the semantic value
582 there is no reason to duplicate this information as Boost.Variants do).
583
584 This implementation reserves a buffer large enough to store the largest
585 objects. yy::variant implements this buffer. It was implemented with
586 Quentin Hocquet.
587
588 * src/output.c (type_names_output): New.
589 (output_skeleton): Invoke it.
590 * data/c++.m4 (b4_variant_if): New.
591 (b4_symbol_value): If needed, provide a definition for variants.
592 * data/lalr1.cc (b4_symbol_value, b4_symbol_action_)
593 (b4_symbol_variant, _b4_char_sizeof_counter, _b4_char_sizeof_dummy)
594 (b4_char_sizeof, yy::variant): New.
595 (parser::parse): If variants are requested, define
596 parser::union_type, parser::variant, change the definition of
597 semantic_type, construct $$ before running the user action instead
598 of performing a default $$ = $1.
599 * examples/variant.yy: New.
600 Based on an example by Michiel De Wilde.
601
602 2008-11-03 Akim Demaille <demaille@gostai.com>
603
604 Parameterize the extraction of semantic values.
605 To make future changes easier, no longer rely on ".TYPE" being the
606 way to get a semantic value.
607
608 * data/c.m4 (b4_symbol_value): New.
609 Use it.
610 * data/c++.m4, data/yacc.c: Use it.
611 * data/glr.c: Use b4_symbol_value.
612 (b4_rhs_data): New.
613 Use it.
614
615 2008-11-03 Akim Demaille <demaille@gostai.com>
616
617 Prepare easier M4 changes.
618 * data/lalr1.cc: Use escaped [] instead of literals to prepare
619 future changes.

637
638 2008-11-02 Joel E. Denny <jdenny@ces.clemson.edu>
639
640 Say %language is experimental.
641 We're thinking of extending it's effect on output file naming. See the

719 Always put auxiliary code files in the same dir as other output files.
720 * src/files.c (compute_file_name_parts): When the user specifies
721 --output but not --file-prefix, extract the directory prefix from the
722 file prefix not from the grammar file name. This affects the location
723 of files like location.hh generated by the C++ skeleton. The includes
724 in the other output files require this fix.
725 * tests/output.at (AT_CHECK_OUTPUT): Automatically create directories
726 for expected output files.

980 * .version.in: Remove.
981 * ChangeLog: Remove the Id previously used for capturing the CVS
982 revision.

987 .prev-version, and .version.
988 * NEWS (2.3b+): Rename to...
989 (?.?): ... this because we're dropping the "+" version naming scheme,
990 but, in general, we still can't be sure of our next release name.
991 * bootstrap: Add a quick hack to remove from .gitignore the
992 GNUmakefile entry that gnulib adds. We already have a /GNUmakefile
993 entry. This should really be fixed in gnulib instead.

1014 Uddeborg at
1015 <http://lists.gnu.org/archive/html/bug-bison/2008-06/msg00000.html>.

1027 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1028 (insert_vc_ignore): ... this new function, which prepends `/' to all
1029 .gitignore entries before passing them to insert_sorted_if_absent.
1030 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1031 .cvsignore files are maintained even though Bison developers run
1032 bootstrap while using Git.
1033 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
1034 unneeded by Bison.
1035 (gnulib): Add.
1036 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
1037 unneeded. Reported by Eric Blake.
1038 * lib/.gitignore (/*~): Add.
1039 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
1040 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
1041 Blake.
1042 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.
1043
1044 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>

1051 (/setenv.m4): Add.
1052 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
1053 the first argument because it may become position-dependent, and unset
1054 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1055 Add comments explaining these issues in more detail.
1056
1057 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

1095 (Release Procedure): Add FIXME about make alpha being unmaintained.
1096

1128 2.61. Reported by Juan Manuel Guerrero at
1129 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
1130 * tests/output.at ("Output file name: ("): Comment out test case for
1131 now.
1132 ("Output file name: )"): Likewise.
1133
1134 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>

1137 succeeds.
1138
1139 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1140
1141 Update to the current gnulib CVS repository, and fix trigraph handling
1142 in Bison.
1143 * bootstrap: Update gnulib CVS repository URL.
1144 (symlink_to_dir): Encapsulate the code that guarantees the destination
1145 directory exists into...
1146 (check_dst_dir): ... this new function, and...
1147 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1148 fail when copying files into lib/uniwidth/.
1149 * src/output.c (prepare_symbols): When writing yytname muscles, where
1150 symbol names will be encoded in C-string literals, tell quotearg to
1151 escape trigraphs. This used to be the default in gnulib.
1152 * tests/regression.at (Token definitions): Because of the change in
1153 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1154 escapes trigraphs in symbol names. Thus, yytname no longer has
1155 trigraphs unnecessarily doubly escaped. Update test case output.
1156 Extend test case to be sure Bison's own error messages will no longer
1157 have trigraphs in symbol names unnecessarily escaped once.

1171 * NEWS (2.3a+): Mention that -g now takes an argument.
1172 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
1173 consistency. Update the -g and -x entries now that they take
1174 arguments. Use brackets to indicate optional arguments.
1175 * src/getargs.c (usage): Explain the relationship between arguments of
1176 long and short options more completely. Document --defines and -d
1177 separately since the former takes an argument but, for POSIX Yacc, the
1178 latter does not.

1192
1193 * src/getargs.c (short_options): Split and sort for readability.
1194 -g and -x take optional arguments, just like their long options.
1195 * build-aux/cross-options.pl: Use /x to make the regexp easier to
1196 understand.
1197 Fix the handling of $opt which resulted in all the argument to be
1198 considered as optional.
1199
1200 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

1812 (xsl:template match="state" mode="conflicts): New.
1813 * src/conflicts.c (conflicts_output_xml): Remove.
1814 * src/conflicts.h (conflicts_output_xml): Remove prototype.
1815 * src/print-xml.c (print_xml): Don't invoke conflicts_output_xml.
1816 * src/print.c (print_grammar): Consistently wrap at the 66th column so
1817 the corresponding XSLT is easier. Also, never wrap between a word and
1818 the comma that follows it.
1819
1820 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>
1821
1822 Improve C++ namespace support. Discussed starting at
1823 <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>.
1824 * data/c++.m4: (b4_namespace_ref, b4_namespace_open,
1825 b4_namespace_close): New macros that interpret the %define variable
1826 "namespace" so its value can contain "::" to indicate nested
1827 namespaces.
1828 * data/glr.cc (b4_namespace): Don't define, and replace all uses with
1829 the above macros.
1830 * data/lalr1.cc (b4_namespace): Likewise.
1831 * data/location.cc (b4_namespace): Likewise.
1832 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
1833 inside a new table in the general %define entry. Document `%define
1834 namespace' there as well. Point the %name-prefix entry to it since it
1835 explains it more completely in the case of C++.
1836 (C++ Bison Interface): Mention `%define namespace' instead of
1837 %name-prefix.
1838 (Table of Symbols): Remove the `%define push_pull' entry. The %define
1839 entry suffices.
1840 * tests/c++.at (Relative namespace references): New test case.
1841 (Absolute namespace references): New test case.
1842 (Syntactically invalid namespace references): New test case.
1843 * tests/input.at (C++ namespace reference errors): New test case.
1844
1845 2007-10-08 Joel E. Denny <jdenny@ces.clemson.edu>

1847 Add syncline support and location accessor to internal %define
1848 interfaces.
1849 * data/bison.m4 (b4_percent_define_get_loc): New.
1850 (b4_percent_define_get_syncline): New.
1851 (b4_percent_define_flag_if): Use b4_percent_define_get_loc.
1852 (b4_percent_define_default): Record defining location as line 1 rather
1853 than 0 for the sake of synchronizing #line's, and define
1854 b4_percent_define_syncline(VARIABLE).
1855 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
1856 * src/muscle_tab.c (muscle_syncline_grow): New.
1857 (muscle_code_grow): Use muscle_syncline_grow.
1858 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
1859 define b4_percent_define_syncline(VARIABLE).
1860 (muscle_percent_define_get_loc): New.
1861 (muscle_percent_define_get_syncline): New.
1862 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
1863 remove some unused variables.
1864 (muscle_percent_define_default): Record defining location as line 1
1865 rather than 0 for the sake of synchronizing #line's, and define
1866 b4_percent_define_syncline(VARIABLE).
1867 (muscle_percent_define_check_values): Use
1868 muscle_percent_define_get_loc.
1869 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
1870 (muscle_percent_define_get_syncline): Prototype.
1871 * tests/skeletons.at (%define Boolean variables: invalid skeleton
1872 defaults): Update output for location change.
1873 (Complaining during macro argument expansion): Extend to test
1874 b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
1875
1876 2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
1877
1878 Fix some error-reporting macro bugs.
1879 * data/bison.m4 (b4_cat): New.
1880 (b4_error, b4_error_at): Use b4_cat to send error directives directly
1881 to stdout so they don't become arguments to other macros. Update
1882 comments and add examples.
1883 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
1884 add examples.
1885 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
1886 after printing the error directive so that M4 doesn't report subsequent
1887 problems that are induced by this problem.
1888 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
1889 instead of just in them. Recognize @\n in both places. Both expand to
1890 the empty string. Needed by b4_cat.
1891 * tests/skeletons.at (Complaining during macro argument expansion):
1892 New test case.
1893 (Fatal errors make M4 exit immediately): New test case.
1894
1895 2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>
1896

1900 (long_options): Add entry for it.
1901 (getargs): Add case for it calling compute_pkgdatadir.
1902 * src/output.c (output_skeleton): Encapsulate data directory
1903 computation from here...
1904 (prepare): ... and from here...
1905 (compute_pkgdatadir): ... into this new function.
1906 * src/output.h (compute_pkgdatadir): Prototype.
1907
1908 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>
1909
1910 * src/print-xml.c (escape_bufs): New static global variable

1917
1918 Replace `%push-parser' and `%push-pull-parser' with
1919 `%define push_pull "push"' and `%define push_pull "both"'.

1921 * doc/bison.texinfo (Push Decl, Push Parser Function,
1922 Pull Parser Function, Parser Create Function, Parser Delete Function):
1923 Update declarations.
1924 (Decl Summary, Table of Symbols): Replace %push-parser and

1926 * data/bison.m4 (b4_percent_define_check_values): New macro.
1927 (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these
1928 definitions...
1929 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
1930 definitions...
1931 * data/push.c: ... to here and compute them from the value of the
1932 %define variable push_pull.
1933 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
1934 parsing requests here...
1935 * data/yacc.c: ... hack this to switch to push.c any time
1936 b4_use_push_pull_flag or the %define variable push_pull is set. This
1937 will go away when we mv push.c yacc.c.
1938 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
1939 push parsing is not supported since unused %define variables are
1940 reported anyway.
1941 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
1942 * src/muscle_tab.h (muscle_percent_define_check_values): Update

1955 (Push Parsing: Multiple impure instances): Update declaration.
1956 (Push Parsing: Unsupported Skeletons): New test case.
1957 * tests/torture.at (Exploding the Stack Size with Alloca): Update
1958 declaration.
1959 (Exploding the Stack Size with Malloc): Update declaration.
1960
1961 2007-09-24 Wojciech Polak <polak@gnu.org>

1974 Problem reported by Wojciech Polak.
1975 * src/print-xml.c (xml_puts): Work even if LEVEL exceeds INT_MAX/2.

1979 2007-09-23 Joel E. Denny <jdenny@ces.clemson.edu>
1980
1981 Pacify ./configure --enable-gcc-warnings.
1982 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
1983 `char const *' instead of `char *'.
1984 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
1985 local variable `sep'.
1986
1987 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
1988
1989 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
1990 elsewhere.
1991 * src/print-xml.c: Prefer "const" after types; that's more consistent.
1992 (xml_printf): Indent just 1 space for level.
1993 (e_char, xlate_char): Remove.
1994 (xml_escape_string): Rewrite to avoid undefined behavior (used
1995 storage that was freed from the stack).
1996 (xml_escape_n): Don't bother checking for subscript error.

2049
2050 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists

2064
2065 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
2066
2067 In impure push mode, don't allow more than one yypstate to be allocated
2068 since multiple impure parsers would corrupt yynerrs.
2069 * data/push.c (yypstate_allocated): New static global variable
2070 initialized to 0.
2071 (yypull_parse): If yypstate_new returns 0, don't report it as memory
2072 exhaustion if yypstate_allocated is 1, but still return 2.
2073 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
2074 already 1. Otherwise, set it to 1.

2148 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2149
2150 Get rid of broken %no-parser, -n, and --no-parser implementation and
2151 documentation.
2152 * TODO: Don't mention them.
2153 * doc/bison.1: Likewise.
2154 * doc/bison.texinfo (Decl Summary): Likewise.
2155 (Bison Options): Likewise.
2156 (Option Cross Key): Likewise.
2157 * src/getargs.c (no_parser_flag): Remove global variable.
2158 (usage): Don't print description of -n and --no-parser.
2159 (long_options): Remove --no-parser entry here.
2160 (getargs): Remove -n case in the switch here.
2161 * src/getargs.h (no_parser_flag): Remove extern.
2162 * tests/regression.at (Web2c Actions): Remove comment that mentions
2163 --no-parser.
2164
2165 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2166
2167 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2168 name user variables starting with `yy'. Just pass NULL instead of a
2169 dummy local &yylval to yypush_parse.
2170 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2171 starting with `yy'.
2172
2173 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2174
2175 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2176 true since it's then always used regardless of whether yyoverflow is
2177 defined. Reported by Christian Burger at
2178 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2179 * THANKS: Add Christian Burger.
2180
2181 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2182 node names: say "Decl Summary" not "Bison Declaration Summary".
2183
2184 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2185
2186 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2187 determine whether this function has already complained about an invalid
2188 value for a %define boolean variable, don't check whether Bison has
2189 ever examined the value. As written, the check was a tautology.
2190 Instead, record and check for this complaint using a separate muscle.
2191
2192 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2193
2194 Fix push parsing memory leak reported by Brandon Lucia at
2195 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2196 * THANKS: Add Brandon Lucia.
2197 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2198 but the parse never completed and thus freed it.
2199 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2200 * tests/testsuite.at: Include push.at.
2201 * test/push.at: New.

2203
2204 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
2205
2206 Improve handling of multiple S/R conflicts in the same state and of S/R
2207 conflicts involving multiple reductions.
2208 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
2209 set for a state here or Bison will abort if it is reassigned on a
2210 later conflicted reduction in the same state.
2211 Similarly, don't finalize and assign the solved conflicts report here
2212 or it will be lost if it is reassigned on a later conflicted reduction
2213 in the same state.
2214 (set_conflicts): Instead, assign them both here after all S/R conflicts
2215 in the state have been fully examined.
2216 * src/print.c (shift_set): Rename to...
2217 (no_reduce_set): ... this.
2218 (print_reductions): Update for rename, and add %nonassoc error action
2219 tokens to no_reduce_set so that, when printing the first remaining
2220 reduction on an error action token, the reduction is enclosed in
2221 brackets.
2222 (print_results): Update for rename.
2223 * tests/conflicts.at (Solved conflicts report for multiple reductions
2224 in a state): New test case.
2225 (%nonassoc error actions for multiple reductions in a state): New test
2226 case.
2227
2228 * src/main.c (main): Don't depend on C99 features.
2229
2230 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2231
2232 * build-aux/.cvsignore: Add compile.
2233 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2234 uniwidth.
2235
2236 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2237
2238 * bootstrap (slurp): Create target directories that don't exist.
2239 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2240
2241 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2242
2243 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2244 than item number.
2245 * closure.c (closure): Likewise.
2246 * state.h (reductions): Comment sorting of rules.
2247 (state): Comment sorting of items.
2248
2249 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2250
2251 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2252 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2253 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2254 definition in order to avoid Gnulib headers since we don't use config.h
2255 here.
2256 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2257 rather than AT_DATA so that config.h is included.
2258
2259 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2260
2261 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2262 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2263 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2264 and so that YYFPRINTF is guaranteed to be defined here.
2265
2266 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2267
2268 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2269 with...
2270 (muscle_percent_define_check_values): ... this more helpful function.
2271 Again, it's not used yet, but it will be.
2272 * src/muscle_tab.h: Likewise.
2273
2274 Improve some comments in parser table construction.
2275 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2276 (generate_states): Don't mention ruleset, which is internal to closure.
2277 * src/closure.c (closure): Explain sorting of core and itemset, which
2278 is required for this function to behave correctly.
2279 * src/closure.h (closure): Mention sorting.
2280
2281 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2282
2283 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2284 move the check for disabled transitions to an aver since conflict
2285 resolution hasn't happened yet.
2286
2287 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2288 labels a state as inconsistent just because it has error transitions.
2289 The original form of this check appeared in revision 1.1 of lalr.c,
2290 which was committed on 1991-12-21. Now (at least), changing the
2291 consistency label on such a state appears to have no useful effect in
2292 any of the places it is examined, which I enumerate below. The key
2293 point to understanding each item in this enumeration is that a state
2294 with an error transition is labelled consistent in the first place only
2295 if it has no rules, so the check cannot matter for states that have
2296 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2297 to try to identify its conflicts, and a state must have *rules* to have
2298 conflicts. (2) Labelling a state as inconsistent will affect how
2299 action_row sets the default *rule* for the state. (3) Labelling a
2300 state as inconsistent will cause build_relations to add lookback edges
2301 to *rules* in that state.
2302 * src/state.h (struct state): Word the comment for member consistent
2303 more carefully.
2304
2305 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2306
2307 Don't depend on C99 features.
2308 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2309 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2310 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2311 * src/state.c (state_mark_reachable_states): Fix for-loop.
2312 (state_remove_unreachable_states): Fix for-loop.
2313
2314 Don't widen struct state with member reachable just to temporarily
2315 record reachability. Instead, use a local bitset.
2316 * src/state.h (struct state): Remove member.
2317 * src/state.c (state_new): Don't initialize it.
2318 (state_mark_reachable_states): Rename to...
2319 (state_record_reachable_states): ... this, and use bitset.
2320 (state_remove_unreachable_states): Use bitset.
2321
2322 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2323
2324 * src/Makefile.am (yacc): Quote target action commands properly so
2325 that the yacc script isn't corrupt. Reported by Hans Aberg at
2326 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2327
2328 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2329 the case of pure parsers. Reported by Frans Englich at
2330 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2331 * THANKS: Add Frans Englich.
2332
2333 * NEWS (2.3a+): In the %code entry, reference section `Bison
2334 Declaration Summary' from the manual now since the %code summary has
2335 moved there.
2336 * doc/bison.texinfo (Prologue Alternatives): Mention that directives
2337 in the rules section must be terminated by semicolons.
2338
2339 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2340
2341 Extend the front-end API for %define variables to more completely
2342 mirror the back-end. This will be useful in the future.
2343 * data/bison.m4 (b4_percent_define_get, b4_percent_define_ifdef):
2344 Update comments to mention the new front-end counterparts of these
2345 macros.

2354 implementation more closely.
2355 (muscle_percent_define_invalid_value): New function.
2356 * src/muscle_tab.h (muscle_percent_define_get,
2357 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2358 Prototype.
2359
2360 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2361
2362 * NEWS (2.3a+): Mention yesterday's state-removal change.
2363 (2.3a): Remove the %language entry, which was added after 2.3a.

2368
2369 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2370
2371 If conflict resolution makes states unreachable, remove those states,
2372 report rules that are then unused, and don't report conflicts in those
2373 states.
2374 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
2375 New global function.

2407 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
2408

2460
2461 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2462
2463 DJGPP spefic issue. Inhibit the use of disallowed characters for
2464 file name genertion on Win98, WinXP, etc. These are |<>":?*\

2484 %define and %code directives.
2485
2486 Make it easy to share %define boolean variables between the front-end
2487 and back-end. Though not used yet, this will be useful in the future.
2488 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about

2505 value for VARIABLE.
2506 (b4_percent_define_default): Save a special location in
2507 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE

2510 functions.
2511 (muscle_percent_define_insert): Record the location of VARIABLE in
2512 muscle percent_define_loc(VARIABLE), and use it to report the previous
2513 location for a redefinition.
2514 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
2515 (muscle_percent_define_default): Update like b4_percent_define_default.
2516 (muscle_grow_user_name_list): Rename to...

2528 equivalent use of yydefact, which was computed in token_actions in
2529 tables.c.
2530 (print_results): Don't allocate lookahead_set.
2531
2532 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2533
2534 * data/lalr1.java: Prefix all private members with yy.
2535
2536 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2537
2538 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2539 Sebastien Fricker at
2540 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2541 * THANKS: Add Sebastien Fricker.

2555
2556 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2557
2558 Undo my 2007-02-07 change, switching back to the c-strcase module
2559 introduced in the 2007-02-03 change. Bruno Haible reported that
2560 the 2007-02-07 change would be dangerous in Turkish if we add a
2561 language whose name contains "i", since "i" is not lowercase "I"
2562 in Turkish.
2563 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2564 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
2565 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
2566 * m4/.cvsignore: Remove strcase.m4.
2567 * src/getargs.c: Revert 2007-02-07 change, as follows.
2568 Include c-strcase.h.
2569 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
2570
2571 2007-02-11 Bruno Haible <bruno@clisp.org>
2572
2573 Enable the Java related testsuite tests when the only Java compiler
2574 found is a gcj < 4.3. Discussed at
2575 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
2576 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
2577
2578 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
2579
2580 * data/Makefile.am: Update copyright date.
2581 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
2582 yypstate_new returns NULL.
2583 (yypstate_new): Return NULL if malloc does.
2584 * src/reader.c (packgram): Move translation of rule actions from the
2585 beginning of packgram to...
2586 (check_and_convert_grammar): ... here right before packgram is invoked
2587 so it's easier to write more complete comments, and remove redundant
2588 code.
2589
2590 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2591
2592 As in semantic actions, make @$ in %initial-action, %destructor, and
2593 %printer imply %locations.
2594 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2595 scanning @$.
2596 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2597 (@$ in %initial-action implies %locations,
2598 @$ in %destructor implies %locations,
2599 @$ in %printer implies %locations): ... these new test cases.
2600
2601 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2602
2603 Undo most of the 2007-02-03 change, switching to the strcase module
2604 now that gnulib strcase has been fixed.
2605 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2606 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2607 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2608 * m4/.cvsignore: Add strcase.m4.
2609 * src/getargs.c: Revert 2007-02-03 change, as follows.
2610 Don't include c-strcase.h.
2611 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2612 strcasecmp has "unspecified behavior" outside the POSIX locale,
2613 but it works fine in practice if at least one argument is ASCII,
2614 as is the case in Bison.
2615
2616 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2617
2618 * tests/java.at: Skip tests if only one of javac/java is present.
2619 Reported by Joel E. Denny.
2620 * tests/atlocal.in: Adjust copyright years.
2621
2622 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2623
2624 * data/lalr1.java (Stack): Work around old verifiers that disallow
2625 access to the private fields of an inner class, from the outer class.
2626 We can make Stack's fields public because user code doesn't have access
2627 to the instance of Stack used by parse(). Reported by Paul Eggert.
2628
2629 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2630
2631 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2632 the right spot for these files?
2633 * bootstrap.conf (gnulib_modules): Add c-strcase.
2634 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2635 c-strncasecmp.c.
2636 * src/getargs.c: Include c-strcase.h.
2637 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2638 to avoid unspecified behavior.
2639
2640 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2641
2642 * doc/bison.texinfo (Decl Summary): Correct typo.
2643
2644 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2645
2646 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
2647 Complain if the value does not match empty, "true" or "false".
2648 * data/c++.m4: Adjust default definitions of %define variables.
2649 * data/java.m4: Adjust default definitions of %define variables.
2650 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
2651 to above behavior.
2652 * tests/input.at (Boolean %define variables): Test new behavior.
2653
2654 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
2655
2656 * NEWS: Mention java.
2657 * TODO: Remove things that are done.
2658 * bootstrap.conf: Add javacomp-script and javaexec-script.
2659 * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
2660
2661 * data/Makefile.am: Add new files.
2662 * data/java-skel.m4: New.
2663 * data/java.m4: New.
2664 * data/lalr1.java: New.
2665
2666 * doc/bison.texinfo: Put "A Complete C++ Example" under
2667 C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
2668 under Other Languages.
2669
2670 * src/getargs.c (valid_languages): Add Java.
2671 * src/getargs.h (struct bison_language): Update size of string fields.
2672
2673 * tests/Makefile.am: Add java.at.
2674 * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
2675 * tests/java.at: New.
2676 * tests/testsuite.at: Include it.
2677
2678 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
2679
2680 Clean up.
2681 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
2682 at_directive_argv arguments so these no longer have to be global
2683 variables. Also, update the implementation for the following changes.
2684 (fail_for_at_directive_too_many_args,
2685 fail_for_at_directive_too_few_args): Add at_directive_name argument.
2686 (at_directive_name): Remove as at_directive_argv[0] will be used for
2687 this now.
2688 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
2689 for the directive name.
2690 (at_directive_argc, at_directive_argv): Make these local within
2691 skel_lex instead of global.
2692 (INITIAL): Update directive start action for above changes.
2693 (SC_AT_DIRECTIVE_ARG): Rename to...
2694 (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
2695 (SC_AT_DIRECTIVE_SKIP_WS): Update.
2696 (scan_skel): Move yylex_destroy to...
2697 (skel_scanner_free): ... here.
2698 * tests/skeletons.at (installed skeleton file name): Rename to...
2699 (installed skeleton file names): ... this.
2700
2701 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
2702
2703 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2704 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
2705 Summary" not "Directives".
2706 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
2707 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
2708 since the former is now the more complete one.
2709 (Prologue Alternatives): Likewise and do the same for %defines.
2710 (Table of Symbols): Add summary of %code, add summary of %define, and
2711 move full %code documentation to...
2712 (Decl Summary): ... here for consistency with other entries in these
2713 sections.
2714 Move %define entry in order to keep this list alphabetized.
2715 Reword %define entry a little to put less emphasis on the skeleton
2716 concept, which most users shouldn't have to think about.
2717
2718 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
2719
2720 Adjust to recent gnulib changes.
2721 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
2722 Add string.h, string_.h, unistd_.h, wchar_.h.
2723 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
2724 * src/system.h: Don't include <stpcpy.h>; this is now done by
2725 <string.h>.
2726
2727 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
2728
2729 Simplify implementation of unqualified %code, implement macros for
2730 uniform treatment of boolean %define flags. Document %define.
2731 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
2732 b4_percent_code_ifdef): New.
2733 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
2734 * data/c++.m4: Define default value for global_tokens_and_yystype.
2735 * data/glr.cc: Likewise.
2736 * data/location.cc: Use b4_percent_define_flag_if.
2737
2738 * doc/bison.texinfo (Decl Summary): Document %define.
2739
2740 * src/parse-gram.y (Unqualified %code): Change muscle name to
2741 b4_percent_code().
2742 (content.opt): Default to empty.
2743
2744 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2745
2746 Implement support for relative and absolute skeleton file names.
2747 Discussed starting at
2748 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
2749 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
2750 (Bison Options): Document in --skeleton entry.
2751 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
2752 full_skeleton can't necessarily hold all of pkgdatadir.
2753 If the specified skeleton file name contains a `/', don't prepend
2754 pkgdatadir.
2755 * src/parse-gram.y (prologue_declaration): If the specified skeleton
2756 file name contains a `/', prepend the grammar file directory.
2757 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
2758 * skeletons.at: New file.
2759 (relative skeleton file names): New test case.
2760 (installed skeleton file names): New test case.
2761 * tests/testsuite.at: Include skeletons.at.
2762
2763 * bootstrap: Update copyright to 2007.
2764
2765 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
2766
2767 * bootstrap: Remove occurrences of .#bootmp from the files.
2768
2769 2007-01-17 Akim Demaille <akim@epita.fr>
2770
2771 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
2772 nonterminals.
2773 Use per-type %printer.
2774
2775 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
2776
2777 * NEWS, data/c++-skel.m4, data/c++.m4, data/c-skel.m4, data/c.m4,
2778 data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,

2782 tests/glr-regression.at, tests/input.at, tests/local.at,
2783 tests/output.at, tests/torture.at: Update copyright to 2007.
2784
2785 2007-01-16 Akim Demaille <akim@epita.fr>
2786
2787 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
2788 error code.
2789 (Calc++ Scanner): Exit with failure if we can't open the input
2790 file.
2791 Accept "-" standing for stdin.
2792 (Calc++ Top Level): Print the result only if the parsing was
2793 successful.
2794
2795 2007-01-16 Akim Demaille <akim@epita.fr>
2796
2797 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
2798
2799 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
2800 and Joel E. Denny <jdenny@ces.clemson.edu>
2801
2802 Clean up %define and %code implementation in M4 some. Most
2803 importantly, rename all related macros to be in the b4_percent_define
2804 and b4_percent_code namespaces. Also, complete support for `.' in
2805 %define variable names and %code qualifiers.
2806 * data/bison.m4 (b4_check_user_names): Check for special
2807 "SKELETON-NAMESPACE(name)" macros instead of using two nested
2808 m4_foreach loops.
2809 (b4_get_percent_define, b4_get_percent_code): Rename to...
2810 (b4_percent_define_get, b4_percent_code_get): ... these.
2811 Extend documentation with examples.
2812 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
2813 b4_percent_define_skeleton_variables and
2814 b4_percent_code_skeleton_qualifiers.
2815 Expect any value for the %define variable `foo' to be stored in the
2816 macro named `b4_percent_define(foo)'; expect any %code blocks for the
2817 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
2818 expect any unqualified %code blocks to be stored in a macro named
2819 `b4_percent_code_unqualified'.
2820 Use m4_indir so that %define variable names and %code qualifiers can
2821 contain `.', which is allowed by the grammar parser.
2822 (b4_percent_define_default): New macro to set a default value for a
2823 %define variable.
2824 (m4_wrap): Update wrapped code, and fix some underquoting.
2825 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
2826 Expect grammar uses of %define variables and %code qualifiers to be
2827 defined in b4_percent_define_user_variables and
2828 b4_percent_code_user_qualifiers.
2829 * data/c++.m4: Use b4_percent_define_default rather than
2830 m4_define_default. Fix some underquoting. Skeleton usage of %define
2831 variable define_location_comparison now implies skeleton usage of
2832 %define variable filename_type.
2833 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
2834 data/push.c, data/yacc.c: Update macro names.
2835 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
2836 muscle names.
2837
2838 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2839
2840 DJGPP specific issues.
2841
2842 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
2843 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
2844
2845 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2846
2847 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
2848 run parsers in all tests so that Valgrind is invoked during
2849 maintainer-check-valgrind.
2850 (Duplicate representation of merged trees): Free all semantic values.
2851 (Duplicated user destructor for lookahead): Likewise.
2852
2853 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2854
2855 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
2856 command-line prefix.
2857 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
2858 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
2859 miss Valgrind messages.
2860 (Exploding the Stack Size with Malloc): Likewise.
2861
2862 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
2863
2864 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
2865 locals. Reported by Juan Manuel Guerrero at
2866 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
2867 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
2868 Fix some indentation also.
2869 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
2870 explaining this issue.
2871
2872 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
2873 and Joel E. Denny <jdenny@ces.clemson.edu>
2874
2875 Simplify union and prologue handling, and escape union and lex/parse
2876 params with digraphs.
2877 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
2878 values to the empty string since these are no longer guaranteed
2879 initialized by the front-end.
2880 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
2881 braces around b4_user_stype since this is no longer done by the
2882 front-end.
2883 * src/files.c, src/files.h (pre_prologue_obstack,
2884 post_prologue_obstack): Remove.
2885 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
2886 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
2887 with digraphs. This fixes lex params and parse params.
2888 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
2889 * src/output.c (prepare): Remove muscle insertion of the prologues.
2890 (output): Remove freeing of pre_prologue_obstack and
2891 post_prologue_obstack.
2892 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
2893 than prologue_augment for prologue parsing so you don't need prologue
2894 obstacks.
2895 (grammar_declaration): For %union RHS, use `braceless' instead of
2896 "{...}" so that braces are already stripped and code is escaped with
2897 digraphs.
2898 * src/reader.c (prologue_augment): Remove.
2899 (reader): Remove initialization of pre_prologue_obstack and
2900 post_prologue_obstack.
2901 * src/reader.h (prologue_augment): Remove.
2902
2903 * data/c.m4: Remove stray parenthesis.
2904
2905 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2906
2907 Remove quotes from variables names in %define directives and from
2908 qualifiers in %code directives, and restrict the characters that are
2909 allowed in them to M4-friendly ones. For %define, continue to support
2910 the quoted form as a deprecated feature. Discussed starting at
2911 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
2912 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
2913 %code.
2914 * doc/bison.texinfo (Prologue Alternatives): Update.
2915 (Decl Summary): In %defines entry, update mention of `%code requires'
2916 and `%code provides'.
2917 (C++ Location Values): Update %define uses.
2918 (Calc++ Parser Interface): Likewise.
2919 (Calc++ Parser): Likewise, and update `%code requires' uses.
2920 (Table of Symbols): Update %code documentation.
2921 * src/parse-gram.y (prologue_declaration): For %define variables, use
2922 `variable' instead of `STRING'.
2923 (grammar_declaration): For %code qualifiers, use `ID' instead of
2924 `STRING'.
2925 (variable): New nonterminal that takes an `ID' or a `STRING'.
2926 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
2927 and %define uses.
2928 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
2929 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
2930 (%define errors): Update %define uses.
2931
2932 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2933
2934 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
2935 instead of muscle_insert for %define values so that M4-special
2936 characters are replaced with digraphs.
2937 * tests/input.at (%define errors): Extend to check weird values.
2938
2939 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
2940
2941 Instead of having skeletons declare all valid %define variables and
2942 %code qualifiers, provide macros that retrieve the associated values
2943 and build these lists automatically. Thus Bison will now warn when a
2944 variable or qualifier is not used by the skeleton in the current
2945 invocation regardless of whether it might sometimes be used by that
2946 skeleton in other invocations. Also, move all %define value macros to
2947 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
2948 form, which is replaced by %code.
2949 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
2950 (b4_check_user_names): ... this, and change the series of valid name
2951 arguments to a single list argument for names used in the skeleton
2952 similar to the existing list argument for names used in the grammar.
2953 Warn instead of complaining.
2954 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
2955 values and %code code, to format %code code properly, and to build
2956 lists of all %define variables and %code qualifiers used in the
2957 skeleton: b4_skeleton_percent_define_variables and
2958 b4_skeleton_percent_code_qualifiers.
2959 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
2960 Remove, and...
2961 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
2962 the skeleton names lists can finish building first. In place of
2963 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
2964 expect the lists b4_user_percent_define_variables and
2965 b4_user_percent_code_qualifiers.
2966 * data/c++.m4: Where setting default values for b4_parser_class_name,
2967 b4_location_type, b4_filename_type, b4_namespace, and
2968 b4_define_location_comparison, update their names to the
2969 b4_percent_define_ namespace.
2970 * data/glr.c: Don't use b4_check_percent_define_variables and
2971 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2972 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
2973 (b4_parser_class_name, b4_namespace): Define these using
2974 b4_get_percent_define for parser_class_name and namespace.
2975 * data/location.cc: Use b4_get_percent_define.
2976 * data/push.c: Don't use b4_check_percent_define_variables and
2977 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
2978 * data/yacc.c: Likewise, and don't call m4_exit in
2979 b4_use_push_for_pull_if or m4_wrap code will never execute.
2980 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
2981 Rename to...
2982 (muscle_grow_user_name_list): ... this for consistency with the
2983 terminology used in bison.m4.
2984 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
2985 %define variable names, and rename muscle used_percent_define_variables
2986 to user_percent_define_variables.
2987 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
2988 user_percent_code_qualifiers.
2989 (content): Remove.
2990 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
2991 {CODE} form is no longer accepted.
2992 * tests/input.at (Reject bad %code qualifiers): Rename to...
2993 (Reject unused %code qualifiers): ... this, and update test output.
2994 (%define error): Update test output.
2995
2996 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
2997
2998 Check for unrecognized %define variables similar to checking for
2999 unrecognized %code qualifiers. Check for redefined %define variables.
3000 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3001 generalizes...
3002 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3003 (b4_check_percent_define_variables): New, also wraps it.
3004 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3005 variables using b4_check_percent_define_variables.
3006 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3007 all those exercised in the test suite and all those listed in the
3008 `Default values' section of c++.m4. Are there others?
3009 * data/push.c, data/yacc.c: Declare no valid %define variables.
3010 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3011 similar to muscle_find, but it works even when the muscle stores a
3012 const value.
3013 (muscle_grow_used_name_list): New function for constructing the used
3014 name list muscles that b4_check_for_unrecognized_names requires.
3015 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3016 %define'd more than once. Define the b4_used_percent_define_variables
3017 muscle with muscle_grow_used_name_list.
3018 (grammar_declaration): Abbreviate %code code with
3019 muscle_grow_used_name_list.
3020 * tests/input.at (%define errors): New.
3021
3022 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3023
3024 Provide warn_at, complain_at, and fatal_at function callbacks to the
3025 skeletons, and use this for %code qualifier complaints.
3026 * data/bison.m4 (b4_error_at): New, invoked by...
3027 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3028 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3029 @fatal_at(...@) directives.
3030 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3031 qualifiers in b4_used_percent_code_qualifiers and to use
3032 b4_complain_at.
3033 * src/location.c, src/location.h (boundary_set_from_string): New global
3034 function.
3035 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3036 function.
3037 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3038 to b4_used_percent_code_qualifiers.
3039 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3040 function.
3041 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3042 (lineno): Rename to...
3043 (out_lineno): ... this so I don't misunderstand it again.
3044 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3045 here; these newlines are in the input but not the output file.
3046 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3047 (at_directive_perform): ... this new static function, and add handling
3048 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3049 directives.
3050 * tests/input.at (Reject bad %code qualifiers): Update test output with
3051 locations and extend.
3052
3053 * tests/output.at (Output file name: [, Output file name: ]): Remove
3054 bogus comment about these tests failing.
3055
3056 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3057
3058 Clean up b4_check_percent_code_qualifiers a little.
3059 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3060 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3061 documentation and add examples.
3062 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3063 qualifiers here.
3064
3065 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3066
3067 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3068 unreliable -- especially when they're hidden inside another macro.
3069 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3070 data/c.m4: Remove m4_divert(-1).
3071 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3072 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3073 m4_divert_push(0) and m4_divert_pop(0).
3074 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3075 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3076 pushed and popped by m4sugar, should be first on the stack.
3077
3078 Provide warn, complain, and fatal function callbacks to the skeletons.
3079 This provides more flexibility than m4_fatal, improves the error
3080 message format, and captures messages for translation. Discussed
3081 starting at
3082 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3083 * data/bison.m4 (b4_error): New, invoked by...
3084 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3085 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3086 directives. Because these M4 macros might be called when the current
3087 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3088 the previous removal of uses of m4_divert, which caused trouble.
3089 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3090 m4_fatal to report unrecognized %code qualifiers.
3091 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3092 push parser requests.
3093 * data/glr.c: Use b4_complain instead of m4_fatal to report
3094 non-deterministic push parser requests.
3095 Update @output usage to @output(...@) form.
3096 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3097 report missing %defines. Update @output usage to @output(...@) form.
3098 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3099 @output(...@) form.
3100 * src/main.c (main): Invoke skel_scanner_free.
3101 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3102 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3103 obstack_for_string from flex-scanner.h.
3104 (YY_DECL): Use to declare skel_lex static.
3105 (decode_at_digraphs): Remove; now handled in the new
3106 SC_AT_DIRECTIVE_ARG start condition.
3107 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3108 functions.
3109 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3110 at_directive_argv): New static globals.
3111 (INITIAL): Use fail_for_invalid_at.
3112 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3113 recognize the start of a generalized `@directive(...@)' form and
3114 start...
3115 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3116 directive args (using the new obstack_for_string), to decode the
3117 contained @ diagraphs, and to perform the directive. It recognizes
3118 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3119 @output(...@).
3120 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3121 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3122 `@,'.
3123 (scan_skel): Initialize obstack_for_string on the first call.
3124 (skel_scanner_free): New function to free obstack_for_string.
3125 * tests/input.at (Reject bad %code qualifiers): Update test output.
3126
3127 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3128
3129 Consolidate the 4 prologue alternative directives (%code, %requires,
3130 %provides, and %code-top) into a single %code directive with an
3131 optional qualifier field. Discussed at
3132 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3133 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3134 alternatives.
3135 * doc/bison.texinfo (Prologue Alternatives): Update.
3136 (Decl Summary): Update to %code "requires" and %code "provides".
3137 (Calc++ Parser): Update to %code "requires".
3138 (Table of Symbols): Remove entries for %requires, %provides, and
3139 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3140 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3141 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3142 which are skeleton-specific.
3143 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3144 declare what %code qualifiers it supports and to complain if any other
3145 qualifiers were used in the grammar.
3146 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3147 and b4_user_code([b4_percent_code_provides]) in place of
3148 b4_user_requires and b4_user_provides.
3149 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3150 Add b4_user_code([b4_percent_code_top]) and
3151 b4_user_code([b4_percent_code]).
3152 Invoke b4_check_percent_code_qualifiers.
3153 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3154 PERCENT_REQUIRES): Remove.
3155 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3156 %requires. Rewrite the %code RHS as the unqualified form defining the
3157 muscle b4_percent_code. Add another RHS for the qualified %code form,
3158 which defines muscles of the form b4_percent_code_QUALIFIER and the
3159 b4_used_percent_code_qualifiers muscle.
3160 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3161 PERCENT_REQUIRES): Remove.
3162 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3163 %code "requires" and %code "provides".
3164 * tests/input.at (Reject bad %code qualifiers): New.
3165
3166 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3167
3168 Use the new code_props interface for destructors and printers.
3169 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3170 printer_location members, and change the type of the destructor and
3171 printer members to code_props.
3172 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3173 symbol_printer_get, semantic_type_destructor_set,
3174 semantic_type_printer_set, default_tagged_destructor_set,
3175 default_tagless_destructor_set, default_tagged_printer_set,
3176 default_tagless_printer_set): Use code_props in arguments and return
3177 types in place of char const * and location.
3178 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3179 since the locations are now contained in the return of
3180 symbol_destructor_get and symbol_printer_get.
3181 * src/output.c (symbol_destructors_output, symbol_printers_output):
3182 Replace with...
3183 (symbol_code_props_output): ... this to eliminate duplicate code.
3184 (output_skeleton): Update to use symbol_code_props_output.
3185 * src/reader.c (symbol_should_be_used): Update use of
3186 symbol_destructor_get.
3187 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3188 Update uses of the various _destructor_set and _printer_set functions.
3189 * src/symtab.c: (default_tagged_destructor_location,
3190 default_tagless_destructor_location, default_tagged_printer_location,
3191 default_tagless_printer_location): Remove since we...
3192 (default_tagged_destructor, default_tagless_destructor,
3193 default_tagged_printer, default_tagless_printer): ... change the type
3194 of these to code_props.
3195 (symbol_new, semantic_type_new, symbol_destructor_set,
3196 semantic_type_destructor_set, symbol_destructor_get,
3197 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3198 symbol_check_alias_consistency, default_tagged_destructor_set,
3199 default_tagless_destructor_set, default_tagged_printer_set,
3200 default_tagless_printer_set): Update.
3201 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
3202 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
3203 code_props members.
3204 (symbol_print): Use SYMBOL_CODE_PRINT.
3205
3206 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3207
3208 Use the new code_props interface for rule actions.
3209 * src/symlist.h (symbol_list): Replace action, action_location, and
3210 used members with a code_props action_props member.
3211 * src/reader.c (symbol_should_be_used, grammar_rule_check,
3212 grammar_midrule_action, grammar_current_rule_merge_set,
3213 grammar_current_rule_symbol_append, packgram): Update.
3214 * src/scan-code.h (translate_rule_action): Remove, no longer used.
3215 * src/scan-code.l (handle_action_dollar): Update.
3216 (translate_rule_action): Remove, no longer used.
3217 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
3218
3219 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3220
3221 Use the new code_props interface in parse-gram.y.
3222 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3223 Update all uses of translate_* functions to use the new code_props
3224 interface and to use gram_scanner_last_string_free and
3225 code_scanner_last_string_free where possible.
3226 (grammar_declaration): symbol_list_destructor_set and
3227 symbol_list_printer_set now perform the translation, so don't do it
3228 here. Use gram_scanner_last_string_free where possible.
3229 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3230 translate_code): Remove, no longer used.
3231 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3232 symbol_list_printer_set): Perform code translation here rather than
3233 depending on the caller to do so.
3234
3235 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3236 * src/scan-gram.h (gram_last_string): Remove declaration.
3237 * src/scan-gram.l (last_string): Declare it static.
3238
3239 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3240
3241 Encapsulate code properties and related functionality for the various
3242 destructors, printers, and actions into a code_props structure and
3243 interface. This patch merely implements code_props in scan-code.h and
3244 scan-code.l. Future patches will rewrite other modules to use it.
3245 Discussed starting at
3246 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3247 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3248 consistently initialize const structs that have an empty location
3249 field.
3250 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3251 to ensure consistency.
3252 * src/scan-code.h (code_props): New structure.
3253 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3254 function, macro, and const global variable for initializing a
3255 code_props with no code.
3256 (code_props_plain_init, code_props_symbol_action_init,
3257 code_props_rule_action_init, code_props_translate_code): The rest of
3258 the new code_props functional interface. Among other things, the init
3259 functions set the code_props kind field so that
3260 code_props_translate_code will know whether to behave like
3261 translate_symbol_action, translate_rule_action, or translate_code.
3262 These old translate functions must remain until all other modules are
3263 updated to use the new code_props interface.
3264 (code_scanner_last_string_free): New function similar to
3265 gram_scanner_last_string_free.
3266 (code_scanner_free): Add documentation.
3267 * src/scan-code.l: Implement the new interface.
3268 (code_lex): Make it static, add a code_props* argument, and remove the
3269 rule argument.
3270 (last_string): New static global similar to the one in scan-gram.l.
3271 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3272 instead of rule.
3273 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3274 code_props since Bison may one day use this information for destructors
3275 and printers.
3276 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3277 (handle_action_dollar): Use symbol_list_n_get and set used flag
3278 directly since symbol_list_n_used_set is removed.
3279 (translate_action): Add a code_props* argument and remove the rule,
3280 action, and location arguments. Pass the code_props* on to code_lex.
3281 (translate_rule_action, translate_symbol_action, translate_code):
3282 Rewrite as wrappers around the new code_props interface.
3283 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3284 it would eventually need to break the encapsulation of code_props.
3285
3286 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3287
3288 * etc/.cvsignore: New.
3289
3290 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3291
3292 Add maintainer-push-check to run maintainer-check using push parsing in
3293 place of pull parsing where available.
3294 * Makefile.am (maintainer-push-check): New.
3295 * data/bison.m4 (b4_use_push_for_pull_if): New.
3296 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3297 appropriately based on their existing values.
3298 (yypush_parse): Don't print push-parser-specific diagnostics if push
3299 parsing is being used in place of pull parsing.
3300 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3301 push.c.
3302 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3303 variable, and insert b4_use_push_for_pull_flag into muscles.
3304 * tests/Makefile.am (maintainer-push-check): New.
3305
3306 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3307
3308 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3309 (whether successful or failed) so that yypush_parse can be invoked
3310 again to start a new parse using the same yypstate.
3311 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3312 check multiple yypull_parse invocations on the same yypstate. For pull
3313 mode, extend to check multiple yyparse invocations.
3314 (Exploding the Stack Size with Alloca): Extend to try with
3315 %push-pull-parser.
3316 (Exploding the Stack Size with Malloc): Likewise.
3317
3318 * tests/calc.at (Simple LALR Calculator): Don't specify
3319 %skeleton "push.c" since %push-pull-parser implies that now.
3320 * tests/headers.at (export YYLTYPE): Don't check for the push
3321 declarations. Otherwise, this test case can't be used to see if push
3322 mode can truly emulate pull mode.
3323 * tests/input.at (Torturing the Scanner): Likewise.
3324 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3325 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3326 AT_YACC_IF, which now includes the case of push mode since %skeleton
3327 need not be used for push mode. This will be more intuitive once
3328 push.c is renamed to yacc.c.
3329
3330 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3331
3332 For push mode, convert yyparse from a macro to a function, invoke yylex
3333 instead of passing a yylexp argument to yypull_parse, and don't
3334 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3335 Discussed starting at
3336 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3337 * data/bison.m4 (b4_pull_if): New.
3338 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3339 * data/push.c: Improve M4 quoting a little.
3340 (b4_generate_macro_args, b4_parenthesize): Remove.
3341 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3342 any time a pull parser is requested.
3343 Don't #define this as a wrapper around yypull_parse. Instead, when
3344 both push and pull are requested, make it a function that does that
3345 same thing.
3346 (yypull_parse): If there's a b4_prefix, #define this to
3347 b4_prefix[pull_parse] when both push and pull are requested.
3348 Don't define this as a function unless both push and pull are
3349 requested.
3350 Remove the yylexp argument and hard-code yylex invocation instead.
3351 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3352 %push-parser.
3353 * src/getargs.c (pull_parser): New global initialized to true.
3354 * getargs.h (pull_parser): extern it.
3355 * src/output.c (prepare): Insert pull_flag muscle.
3356 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3357 (prologue_declaration): Set both push_parser and pull_parser = true for
3358 %push-pull-parser. Set push_parser = true and pull_parser = false for
3359 %push-parser.
3360 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3361 %push-parser since there's no backward-compatibility concern here.
3362 Scan %push-pull-parser.
3363 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3364 instead of %push-parser.
3365 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3366 prototype it in the module that calls yyparse.
3367 * tests/input.at (Torturing the Scanner): Likewise.
3368 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3369
3370 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3371
3372 Update etc/bench.pl. Optimize push mode a little (the yyn change
3373 deserves most of the credit).
3374 * Makefile.am (SUBDIRS): Add etc subdirectory.
3375 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3376 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3377 yytoken, yyval, and yyloc declarations to...
3378 (yyparse or yypush_parse): ... here to improve performance. For
3379 yypush_parse invocations after the first, be sure to assign yyn its old
3380 value again.
3381 (yypstate_new): Don't bother initializing the yyresult field since the
3382 initial value isn't used.
3383 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3384 remove the #define that, in push mode, set it to yyps->NAME.
3385 * etc/Makefile.am: New.
3386 * etc/bench.pl: Remove and build it instead from...
3387 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3388 "tests/bison" from the build directory by default rather than just
3389 invoking "bison" from $PATH.
3390 (calc_grammar): Update push parser code: don't declare yylval globally,
3391 don't define yyparse_wrapper, and don't #define yyparse.
3392 (bench_grammar): Update to check all working combinations of yacc.c,
3393 push.c, impure, pure, pull, and push.
3394
3395 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3396
3397 For push mode, add pull wrappers around yypush_parse.
3398 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3399 (yypull_parse): New function wrapping yypush_parse.
3400 (yyparse): New #define wrapping yypull_parse.
3401 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3402 is declared.
3403 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3404 prototype yylex in the module that calls yyparse, and don't prototype
3405 yyparse there. Otherwise, the yyparse expansion won't compile.
3406 * tests/input.at (Torturing the Scanner): Likewise.
3407
3408 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3409
3410 Enable push parsers to operate in impure mode. Thus, %push-parser no
3411 longer implies %pure-parser. The point of this change is to move
3412 towards being able to test the push parser code by running the entire
3413 test suite as if %push-parser had been declared.
3414 * data/push.c (yypush_parse): For impure mode, remove the
3415 yypushed_char, yypushed_val, and yypushed_loc arguments.
3416 Instead, declare these as local variables initialized to the global
3417 yychar, yylval, and yylloc.
3418 For the first yypush_parse invocation only, restore the initial values
3419 of these global variables when it's time to read a token since they
3420 have been overwritten.
3421 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3422 %push-parser.
3423 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3424 %pure-parser along with %push-parser since this test case was designed
3425 for pure push parsers.
3426 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3427 (AT_YACC_OR_PUSH_IF): New.
3428 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3429 add a note that it's still wrong for some cases (as it has been for a
3430 while).
3431 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3432 %push-parser no longer implies %pure-parser.
3433
3434 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3435
3436 Remove some unnecessary differences between the pull parser code and
3437 the push parser code. This patch enables yynerrs in push mode.
3438 * data/push.c: Reformat M4 a little.
3439 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3440 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3441 because push mode is on. Instead, if pure mode is on, move yynerrs
3442 to...
3443 (b4_declare_parser_state_variables): ... here.
3444 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3445 to yyps->NAME so it can be used in yypush_parse.
3446 (yypush_parse): Don't omit uses of yynerrs in push mode.
3447
3448 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3449
3450 Fix bug such that the first pushed token's value and location are
3451 sometimes overwritten (sometimes by %initial-action) before being used.
3452 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3453 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3454 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3455 more closely mimic the pull parser logic.
3456 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3457 time to read a token, which is after any initialization of yylval and
3458 yylloc.
3459 (gottoken): Rename label to...
3460 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3461 user namespace.
3462
3463 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3464
3465 Rearrange initialization of the parser state variables so that the
3466 skeleton doesn't have to have a copy for pull mode and another for push
3467 mode. This patch also fixes at least a bug such that yylloc was not
3468 initialized (with b4_location_initial_line and
3469 b4_location_initial_column) upon calling yypush_parse. However, that
3470 initialization now overwrites the first token's location;
3471 %initial-action assigning @$ already did the same thing, and both bugs
3472 will be fixed in a later patch.
3473 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3474 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3475 yyss, yyvs, yyls, and yystacksize.
3476 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3477 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3478 yylsp.
3479 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3480 yyps->NAME so it can be used in yypush_parse.
3481 (yyparse or yypush_parse): For yypush_parse, don't print the
3482 "Starting parse" diagnostic for invocations after the first.
3483 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3484 yypush_parse, only do it for the first invocation.
3485 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3486 initialization to occur in yypush_parse but only on the first
3487 invocation.
3488
3489 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3490
3491 * data/push.c: Add CPP guards around push parser declarations in both
3492 the header and the code file.
3493 In the code file, move the push parser declarations to the same place
3494 they appear in the header file.
3495 Clean up the M4 some, especially the inconsistent underquoting in
3496 some b4_c_function_def and b4_c_function_decl uses.
3497
3498 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3499
3500 Encapsulate the push parser state variables into an M4 macro so the
3501 push skeleton doesn't have to list them again for pull mode's yyparse.
3502 For push mode, remove yypush_parse's local equivalents of these
3503 variables to eliminate unnecessary copying between the two sets at
3504 run-time. This patch also fixes at least a bug related to multiple
3505 %initial-action invocations in push mode.
3506 * data/push.c (b4_declare_parser_variables): Rename to...
3507 (b4_declare_scanner_communication_variables): ... this for clarity and
3508 update both uses.
3509 (b4_declare_yyparse_variables): Remove and move its contents to the one
3510 spot where it was invoked.
3511 (b4_declare_parser_state_variables): New macro containing the parser
3512 state variables required by push mode.
3513 (struct yypstate): Replace all fields but yynew with
3514 b4_declare_parser_state_variables.
3515 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3516 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3517 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3518 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3519 parser state variable declarations with
3520 b4_declare_parser_state_variables.
3521 Don't initialize parser state variables when calling yypush_parse since
3522 yypstate_new already does that.
3523 Invoke the user's initial action only upon the first yypush_parse
3524 invocation.
3525 Remove all code that copies between the local parser state variables
3526 and the yypstate.
3527
3528 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3529
3530 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3531 prevent a name collision in a future patch where these names will
3532 sometimes be #define'd.
3533 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3534 since it no longer has the same name as the existing argument.
3535 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3536
3537 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3538 and Joel E. Denny <jdenny@ces.clemson.edu>
3539
3540 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3541 that the argument is case-insensitive, and there's no `=' here.
3542 For the %skeleton entry, mention that %language is better.
3543 (Bison Options): Likewise for --language and --skeleton. Move the
3544 --skeleton entry so that the `Tuning the parser' section is sorted
3545 alphabetically on long options.
3546 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3547 %language directive in detail here; cross-reference the %language
3548 documentation instead.
3549 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3550 `%require "2.3b"' so that the example is always up-to-date.
3551 (Table of Symbols): Add entries for %language and %skeleton.
3552 * examples/extexi (normalize): Instead of replacing every %require
3553 argument with the current Bison version, just substitute for
3554 `@value{VERSION}'. This guarantees that we're testing what actually
3555 appears in the documentation.
3556 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3557 rather than `@VERSION@'.
3558
3559 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3560
3561 * NEWS: Reword the %language news a bit, and put it earlier.
3562
3563 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3564 Rewrite to simplify the logic.
3565 (language_argmatch): Likewise.
3566 (program_name): We now own this var.
3567 * src/getargs.h (struct bison_language): Use char[] rather than
3568 const char *.
3569
3570 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3571 Java is supported.
3572 * src/complain.c (program_name): Remove decl; no longer needed.
3573 * src/main.c (program_name): Remove; now belongs to getargs.
3574
3575 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3576
3577 * NEWS: Document %language.
3578
3579 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3580
3581 * data/c-skel.m4, data/c++-skel.m4: New files.
3582 * data/glr.c: Complain on push parsers.
3583
3584 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3585 over %skeleton.
3586 (Decl Summary): Document %language and %skeleton.
3587 (Command line): Document -L.
3588
3589 * examples/extexi: Rewrite %require directive.
3590 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3591
3592 * src/files.c (compute_exts_from_gc): Look in language structure
3593 for .y extension.
3594 (compute_file_name_parts): Check whether .tab should be added.
3595 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3596 (language, skeleton_arg, language_argmatch): New.
3597 (long_options): Add --language.
3598 (getargs): Use skeleton_arg, add -L/--language.
3599 * src/getargs.h: Include location.h.
3600 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3601 * src/output.c (prepare): Pick default skeleton from struct language.
3602 Don't dispatch C skeletons here.
3603 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3604 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3605 * src/scan-gram.l ("%language"): New rule.
3606
3607 * tests/calc.at: Test %skeleton and %language.
3608 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3609 (AT_GLR_IF): Look for %skeleton "glr.cc".
3610 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3611 (AT_YACC_IF): Reject %language.
3612
3613 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3614
3615 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3616 since it wasn't used; only the typedef name 'semantic_type' is needed.
3617 Also, omit trailing white space.
3618
3619 * bootstrap: Sync from coreutils.
3620 (gnulib_extra_files): Add build-aux/announce.gen.
3621 (slurp): Adjust .gitignore files like .cvsignore files.
3622 * build-aux/announce-gen: Remove from CVS, since bootstrap
3623 now creates this.
3624
3625 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3626
3627 Make %push-parser imply %pure-parser. This fixes several bugs; see
3628 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3629 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3630 pure_parser = true.
3631 * data/push.c: Don't bother testing b4_push_if when deciding whether
3632 to expand b4_declare_parser_variables globally.
3633 (yypush_parse): Likewise in here.
3634
3635 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3636 (yy_reduce_print): Reformat M4 for readability.
3637
3638 2006-12-15 Bob Rossi <bob@brasko.net>
3639 and Joel Denny <jdenny@ces.clemson.edu>
3640
3641 * data/push.c (yypstate): Add typedef, and update all uses of
3642 struct yypstate to just yypstate.
3643 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3644
3645 2006-12-14 Bob Rossi <bob@brasko.net>
3646
3647 * data/push.c (yypush_parse): Declare prototype regardless of
3648 %locations option.
3649
3650 2006-12-14 Bob Rossi <bob@brasko.net>
3651
3652 * data/push.c (yyparse): Remove the prototype and the #define when in
3653 push-parser mode.
3654
3655 2006-12-13 Bob Rossi <bob@brasko.net>
3656
3657 * data/push.c (yypstate_init): Rename to...
3658 (yypstate_new): ... this and use b4_c_function_def.
3659 (yypstate_delete): New.
3660 (yypush_parse): Change parameters yynval and yynlloc to be const.
3661 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
3662 yypstate_delete functions.
3663
3664 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
3665
3666 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
3667 strange test case titles. Reported by Bob Rossi.
3668
3669 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
3670
3671 * TODO: Add pointer to Sylvain Schmitz's work on static detection
3672 of potential ambiguities in GLR grammers.
3673
3674 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
3675
3676 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
3677 `bison ', use m4_index instead of m4_substr since chopping up a string
3678 containing M4-special characters causes problems here.
3679
3680 Fix a couple of bugs related to special characters in user-specified
3681 file names, and make it easier for skeletons to compute output file
3682 names with the same file name prefix as Bison-computed output file
3683 names.
3684 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
3685 b4_parser_file_name and b4_spec_defines_file instead of
3686 @output_parser_name@ and @output_header_name@, which are now redundant.
3687 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
3688 b4_parser_file_name, b4_spec_defines_file, and the new
3689 @basename(FILENAME@) instead of @output_parser_name@ and
3690 @output_header_name@, which inappropriately escaped the file names as
3691 C string literals.
3692 * src/files.c (all_but_ext): Remove static qualifier.
3693 (compute_output_file_names): Move `free (all_but_ext)' to...
3694 (output_file_names_free): ... here since all_but_ext is needed later.
3695 * src/files.h (all_but_ext): Extern.
3696 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
3697 exactly what MUSCLE_INSERT_STRING used to do.
3698 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
3699 characters are escaped properly.
3700 * src/output.c (prepare): Define muscle file_name_all_but_ext as
3701 all_but_ext.
3702 For pkgdatadir muscle, maintain previous functionality by using
3703 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
3704 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
3705 digraphs would never be expanded. Hopefully no one has M4-special
3706 characters in his Bison installation path.
3707 * src/scan-skel.l: Don't parse @output_header_name@ and
3708 @output_parser_name@ anymore since they're now redundant.
3709 In @output, use decode_at_digraphs.
3710 Parse a new @basename command that invokes last_component.
3711 (decode_at_digraphs): New.
3712 (BASE_QPUTS): Remove unused.
3713 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
3714 (Output file name): New tests.
3715
3716 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
3717
3718 Warn about output files that are generated by the skeletons and that
3719 conflict with other output files.
3720 * data/glr.c: Don't generate the header file here when glr.cc does.
3721 * src/files.c (file_names, file_names_count): New static globals.
3722 (compute_output_file_names): Invoke output_file_name_check for files
3723 not generated by the skeletons and remove existing checks.
3724 (output_file_name_check): New function that warns about conflicting
3725 output file names.
3726 (output_file_names_free): Free file_names.
3727 * src/files.h (output_file_name_check): Declare.
3728 * src/scan-skel.l: Invoke output_file_name_check for files generated by
3729 the skeletons.
3730 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
3731 (Conflicting output files): New tests.
3732
3733 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3734
3735 * doc/bison.texinfo: Fix a couple of typos.
3736
3737 2006-12-08 Bob Rossi <bob@brasko.net>
3738
3739 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
3740 Rename to...
3741 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
3742 update all uses.
3743 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
3744 (yypush_parse): Rename yypvars argument to yyps and remove redundant
3745 local pv.
3746 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
3747 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
3748
3749 2006-12-07 Bob Rossi <bob@brasko.net>
3750 and Joel Denny <jdenny@ces.clemson.edu>
3751
3752 * data/push.c (yypvarsinit): Change return type from void* to struct
3753 yypvars*. No longer cast to void* on return.
3754 (struct yypvars): Remove yylen since it need not be remembered between
3755 yypushparse invocations.
3756 (yypushparse): Don't copy between yylen and pv->yylen.
3757
3758 2006-12-05 Bob Rossi <bob@brasko.net>
3759
3760 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
3761 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
3762 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
3763 (struct yypvars): Remove b4_declare_parser_variables.
3764 (yypvarsinit): Remove init code for removed variables.
3765 (global scope): Do not declare b4_declare_parser_variables if
3766 push or pure mode.
3767 (yypushparse): Add b4_declare_parser_variables.
3768 Init new local variables, and remove init code for removed
3769 yypvars variables.
3770 (yyparse): Delete.
3771 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
3772 and yyparse for other modes.
3773 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
3774 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
3775 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
3776 (AT_PURE_LEX_IF): True if pure or push parser.
3777
3778 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>
3779
3780 Document Yacc prologue alternatives and default %destructor's and
3781 %printer's as experimental. Don't mention Java yet. Discussed at
3782 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00002.html>.
3783 * NEWS (2.3a+): Say they're experimental. Remove any mention of Java.
3784 (2.3a): Annotate this entry to say the old forms of these features were
3785 also experimental.
3786 * doc/bison.texinfo (Prologue Alternatives, Freeing Discarded Symbols,
3787 Table of Symbols): Say they're experimental. Comment out any mention
3788 of Java (we'll want this back eventually).

3790 2006-12-01 Joel E. Denny <jdenny@ces.clemson.edu>
3791
3792 Support a file name argument to %defines. Deprecate `=' in
3793 %file-prefix, %name-prefix, and %output. Discussed at
3794 <http://lists.gnu.org/archive/html/help-bison/2006-09/msg00001.html>.
3795 * NEWS (2.3a+): Mention.
3796 * doc/bison.texinfo (Decl Summary, Table of Symbols): Add entry for new
3797 form of %defines, and remove `=' from entries for %file-prefix,

3805 * tests/output.at (AT_CHECK_OUTPUT): Remove the `=' from all but one
3806 occurrence of each of %file-prefix and %output. Add check for %defines
3807 with argument.
3808 * tests/reduce.at (Useless Terminals, Useless Nonterminals,
3809 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
3810 Remove the `=' from %output.
3811
3812 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
3813
3814 Don't escape $ in test case titles since Autoconf 2.61 now does that
3815 correctly.
3816 * tests/actions.at (Default %printer and %destructor are not for error
3817 or $undefined): Here.
3818 (Default %printer and %destructor are not for $accept): Here.
3819 * tests/input.at (Invalid $n and @n): Here.
3820
3821 2006-11-20 Joel E. Denny <jdenny@ces.clemson.edu>
3822
3823 Rename <!> to <>. Discussed starting at
3824 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00039.html>.
3825 * NEWS (2.3a+): Update.
3826 * doc/bison.texinfo (Freeing Discarded Symbols, Table of Symbols):
3827 Update.
3828 * src/parse-gram.y (TYPE_TAG_NONE, generic_symlist_item): Implement.
3829 * src/scan-gram.l (INITIAL): Implement.
3830 * src/symlist.c (symbol_list_default_tagless_new): Update comment.
3831 * src/symlist.h (symbol_list, symbol_list_default_tagless_new): Update
3832 comment.
3833 * tests/actions.at (Default tagless %printer and %destructor,
3834 Default tagged and per-type %printer and %destructor,
3835 Default %printer and %destructor are not for error or $undefined,
3836 Default %printer and %destructor are not for $accept,
3837 Default %printer and %destructor for mid-rule values): Update.
3838 * tests/input.at (Default %printer and %destructor redeclared,
3839 Unused values with default %destructor): Update.
3840
3841 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
3842
3843 Don't let %prec take a nonterminal.
3844 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
3845 token.
3846 * tests/input.at (%prec takes a token): New test checking that %prec
3847 won't take a nonterminal.
3848
3849 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3850
3851 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
3852 it was double-quoted.
3853 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
3854 grammar is maintained with Bison's highest standards.
3855 * src/getargs.c: Fix some typos in Doxygen comments.
3856
3857 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
3858
3859 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
3860 later. Reported by Paul Eggert in
3861 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
3862 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
3863 * src/scan-code.l (translate_action): Don't bother invoking
3864 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
3865 (code_scanner_free): Instead of invoking
3866 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
3867 which frees more.
3868 * src/scan-gram.l (gram_scanner_free): Likewise.
3869 * src/scan-skel.l (scan_skel): Likewise.
3870
3871 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
3872
3873 * src/files.c (tr): Change return type to void.
3874 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
3875 has been called previously for the same key.
3876 (muscle_find): Return storage instead of value so that
3877 --enable-gcc-warnings doesn't produce warnings that the return discards
3878 const. aver that the value and storage are the same since storage
3879 could potentially be NULL when value is not.
3880 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
3881 same as 0.
3882
3883 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3884
3885 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
3886 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
3887 us a slightly cleaner distribution, and also works.
3888 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
3889 gnulib changes.
3890
3891 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
3892 and Paul Eggert <eggert@cs.ucla.edu>
3893
3894 Don't let Bison leak memory except when it complains.
3895 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
3896 (spec_defines_file, dir_prefix): Now char *, not const char *,
3897 since they are freed.
3898 * src/files.c: Likewise.
3899 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
3900 Likewise.
3901 (tr): Now operates in-place. All uses changed.
3902 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
3903 values.
3904 (compute_file_name_parts, compute_output_file_names): Don't store
3905 read-only data in variables that will be freed.
3906 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
3907 src_extension, and header_extension.
3908 (output_file_names_free): New public function to free
3909 spec_verbose_file, spec_graph_file, spec_defines_file,
3910 parser_file_name, and dir_prefix.
3911 * src/getargs.c (getargs): Don't store read-only data in variables that
3912 will be freed.
3913 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
3914 (which previously existed but was unused), and quotearg_free.
3915 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
3916 * src/muscle_tab.c: Likewise.
3917 (muscle_entry): Make the value char const *,
3918 and add a new storage member that is char * and can be freed.
3919 (muscle_entry_free): New private function.
3920 (muscle_init): Use it instead of free.
3921 (muscle_insert, muscle_grow): Update and use new storage member.
3922 (muscle_code_grow): Free the string passed to muscle_grow
3923 since it's not needed anymore.
3924 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
3925 add a new `char *code' member.
3926 ("{...}"): Declare semantic type as code.
3927 * src/scan-code.h (translate_rule_action):
3928 (translate_symbol_action, translate_code, translate_action): Return
3929 `char const *' rather than `char *' since external code should not free
3930 these strings.
3931 * src/scan-code.l: Likewise.
3932 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
3933 which is "{...}" in the parser.
3934 * tests/Makefile.am (maintainer-check-valgrind): Set
3935 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
3936 Valgrind.
3937 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
3938 complain.
3939 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
3940 expecting a non-zero exit status sets --leak-check=summary and
3941 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
3942 this case, and we don't want to hear about it.
3943
3944 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
3945
3946 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
3947 instead of from the template, to simplify configuration a bit.
3948 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
3949 and m4/wint_t.m4, as they are needed with the latest gnulib.
3950
3951 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3952
3953 Disable unset/unused mid-rule value warnings by default, and recognize
3954 --warnings=midrule-values to enable them. Discussed starting at
3955 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
3956 * NEWS (2.3a+): Mention.
3957 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
3958 warnings): Add entry for midrule-values subargument.
3959 * src/reader.c (symbol_should_be_used): Don't return true just because
3960 the value is a set/used mid-rule value unless
3961 --warnings=midrule-values was specified.
3962 * tests/input.at (Unused values, Unused values before symbol
3963 declarations): Run tests with and without --warnings=midrule-values.
3964
3965 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
3966 than LIST_FREE directly.
3967
3968 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3969
3970 Finish implementing --warnings=error, which should not be implied by
3971 --warnings=all (or by its synonyms -W and --warnings without
3972 subarguments).
3973 * src/complain.c (set_warning_issued): New function to report that
3974 warnings are being treated as errors and to record an error if so.
3975 Invoke...
3976 (warn_at, warn): ... here.
3977 * src/getargs.c (warnings_args, warnings_types): Reorder so that
3978 "error - warnings are errors" does not appear above "all - all of the
3979 above".
3980 (getargs): For -W and --warnings without subarguments, don't let
3981 FLAGS_ARGMATCH set warnings_error in warnings_flag.
3982 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
3983
3984 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
3985
3986 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
3987 empty subargument list. For example: `bison --warnings= parser.y'.
3988
3989 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3990
3991 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
3992 the parser header file so that gcc doesn't warn.
3993
3994 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
3995
3996 Split the default %destructor/%printer into two kinds: <*> and <!>.
3997 Discussed starting at
3998 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
3999 * NEWS (2.3a+): Mention.
4000 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
4001 previous change today related to mid-rules.
4002 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
4003 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
4004 (TYPE_TAG_ANY): Add as <*>.
4005 (TYPE_TAG_NONE): Add as <!>.
4006 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
4007 for <*> and <!>.
4008 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
4009 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
4010 * src/symlist.c (symbol_list_default_new): Split into tagged and
4011 tagless versions.
4012 (symbol_list_destructor_set, symbol_list_printer_set): Split
4013 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
4014 SYMLIST_DEFAULT_TAGLESS.
4015 * src/symlist.h: Update symbol_list_default*_new prototypes.
4016 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
4017 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
4018 * src/symtab.c (default_destructor, default_destructor_location,
4019 default_printer, default_printer_location): Split each into tagged and
4020 tagless versions.
4021 (symbol_destructor_get, symbol_destructor_location_get,
4022 symbol_printer_get, symbol_printer_location_get): Implement tagged
4023 default and tagless default cases.
4024 (default_destructor_set, default_printer_set): Split each into tagged
4025 and tagless versions.
4026 * src/symtab.h: Update prototypes.
4027 * tests/actions.at (Default %printer and %destructor): Rename to...
4028 (Default tagless %printer and %destructor): ... this, and extend.
4029 (Per-type %printer and %destructor): Rename to...
4030 (Default tagged and per-type %printer and %destructor): ... this, and
4031 extend.
4032 (Default %printer and %destructor for user-defined end token): Extend.
4033 (Default %printer and %destructor are not for error or $undefined):
4034 Update.
4035 (Default %printer and %destructor are not for $accept): Update.
4036 (Default %printer and %destructor for mid-rule values): Extend.
4037 * tests/input.at (Default %printer and %destructor redeclared): Extend.
4038 (Unused values with default %destructor): Extend.
4039
4040 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4041
4042 Don't apply the default %destructor/%printer to an unreferenced midrule
4043 value. Mentioned at
4044 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4045 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4046 like $@n instead of just @n so that the default %destructor/%printer
4047 logic doesn't see them as user-defined symbols.
4048 (symbol_is_dummy): Check for both forms of the name.
4049 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4050 name for which the midrule value is referenced in any action.
4051 * tests/actions.at (Default %printer and %destructor for mid-rule
4052 values): New test.
4053 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output

4056 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
4057
4058 Warn about unset midrule $$ if the corresponding $n is used.
4059 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
4060 $n usage.
4061 (packgram): Before invoking grammar_rule_check on any rule, make sure
4062 all actions have already been scanned in order to set `used' flags.
4063 Otherwise, checking that a midrule's $$ is set will not always work
4064 properly because the midrule check must forward-reference the midrule's
4065 parent rule.
4066 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
4067 warning.
4068
4069 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
4070
4071 More improvements to the documentation of the prologue alternatives:
4072 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
4073 Bison manual.
4074 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
4075 some text to clarify the relative importance of the new directives and
4076 to show how these directives may be viewed as code labels.
4077
4078 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4079
4080 Similar to the recently removed %before-header, add %code-top as the
4081 alternative to the pre-prologue. Mentioned at
4082 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
4083 Also, let the prologue alternatives appear in the grammar section.
4084 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
4085 (prologue_declaration): Move the existing prologue alternatives to...
4086 (grammar_declaration): ... here and add %code-top.
4087 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
4088
4089 Clean up and extend documentation for the prologue alternatives.
4090 * NEWS (2.3a+): Describe prologue alternatives.
4091 * doc/bison.texinfo (Prologue): Move discussion of prologue
4092 alternatives to...
4093 (Prologue Alternatives): ... this new section, and extend it to discuss
4094 all 4 directives in detail.
4095 (Table of Symbols): Clean up discussion of prologue alternatives and
4096 add %code-top.

4135 (Sync from coreutils.)
4136 Work also when the working directory (with e.g. coreutils sources)
4137 is version controlled with git, rather than CVS.
4138 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
4139 rather than CVS.

4146 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
4147
4148 Fix testsuite for ./configure --enable-gcc-warnings:
4149 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
4150 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
4151 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
4152 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
4153 * test/regression.at (Diagnostic that expects two alternatives):
4154 Likewise.

4193 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4194 variable was sometimes used without being initialized. This
4195 messed up the installation of the INSTALL file in some cases.
4196
4197 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4198
4199 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4200 --copy. Inspired by a suggestion from Bruno Haible.
4201
4202 2006-10-03 Jim Meyering <jim@meyering.net>
4203
4204 * bootstrap: Undo last change to this file, since now gnulib-tool
4205 sticks with the automake default in generating dependencies.
4206
4207 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4208
4209 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
4210 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
4211
4212 * doc/bison.1: Add copyright notice.
4213
4214 * data/glr.c: Don't include <stdarg.h>; not used.
4215
4216 * NEWS: The -g and --graph options now output graphs in Graphviz
4217 DOT format, not VCG format.
4218 * doc/bison.1: Likewise.
4219 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
4220 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
4221 of this change in
4222 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
4223 * TODO: Remove Graphviz entry.
4224 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
4225 remove vcg.c, vcg.h, vcg_defaults.h.
4226 * src/vcg.c, src/vcg.h, src/vcg_defaults.h: Remove.
4227 * src/graphviz.c, src/graphviz.h: New files.
4228 * src/files.c (compute_output_file_names): Output .dot, not .vcg.
4229 * src/files.h: Make comment more generic.
4230 * src/main.c (main): Likewise.
4231 * src/print_graph.h: Likewise.
4232 * src/getargs.c (usage): Make usage description more generic.
4233 * src/print_graph.c: Include graphviz.h rather than vcg.h.
4234 (static_graph, fgraph): Remove. All uses changed to pass
4235 arguments instead of sharing a static var.
4236 (print_core, print_actions, print_state, print_graph):
4237 Output graphviz format rather than VCG format.
4238 * tests/.cvsignore: Remove *.vcg; add *.dot.
4239 * tests/output.at: Expect *.dot files, not *.vcg files.
4240
4241 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
4242 accommodates the 2006-10-08 change.
4243
4244 2006-10-11 Bob Rossi <bob@brasko.net>
4245
4246 * data/push.c (yypushparse, yypvarsinit, yypvars): Wrap in b4_push_if.
4247 (b4_yyssa, b4_yyerror_range): New macros.
4248 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
4249 (yypvarsinit): Remove init of removed fields.
4250 (yypushparse): Remove use of removed fields; use new macros instead.
4251
4252 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4253
4254 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
4255 in a push parser. Reindent slightly to match yacc.c better.
4256
4257 2006-10-11 Bob Rossi <bob@brasko.net>
4258
4259 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
4260 yymsg_alloc fields.
4261 (yypvarsinit, yypushparse): Remove init of removed fields.
4262 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
4263
4264 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4265
4266 * THANKS: Add Paolo Bonzini and Bob Rossi.
4267
4268 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
4269
4270 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
4271 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
4272 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
4273 b4_define_user_cde and uses): Remove.
4274 (b4_comment, b4_prefix, b4_sync_start): New.
4275 * data/bison.m4: New file, with most of the content removed from c.m4.
4276 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
4277 * src/output.c (output_skeleton): Pass bison.m4.
4278 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
4279 only if specified.
4280
4281 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
4282
4283 Fix test failure reported by Tom Lane in
4284 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
4285 and try to make such failures easier to catch in the future.
4286 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
4287 that's now the caller's responsibility.
4288 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
4289 Set yychar = YYEOF if it's negative.
4290 * tests/actions.at (yylex): Abort if asked to read past EOF.
4291 * tests/conflicts.at (yylex): Likewise.
4292 * tests/cxx-type.at (yylex): Likewise.
4293 * tests/glr-regression.at (yylex): Likewise.
4294 * tests/input.at (yylex): Likewise.
4295 * tests/regression.at (yylex): Likewise.
4296 * tests/torture.at (yylex): Likewise.
4297
4298 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
4299
4300 Fix problems with translating English-language diagnostics.
4301 * bootstrap: Fix bug introduced in recent bootstrap changes, with
4302 respect to bison-runtime pot generation. The YY_ stuff
4303 wasn't being captured.
4304 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
4305 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
4306 * runtime-po/POTFILES.in: Add data/push.c.
4307
4308 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
4309
4310 Merge bootstrap changes from coreutils.
4311
4312 2006-09-28 Jim Meyering <jim@meyering.net>
4313
4314 Automatically generated dependencies are important even
4315 when all of the sources in a directory come from gnulib.
4316 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
4317 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
4318
4319 2006-09-23 Jim Meyering <jim@meyering.net>
4320
4321 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
4322
4323 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4324
4325 * bootstrap: Add support for --force.
4326 (usage): New function. Describe usage less tersely.
4327 (CVS_only_file): New var.
4328
4329 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
4330
4331 * data/push.c (YYPUSH_MORE): Make it an enum instead.
4332 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
4333 Adjust white space and comments to match GNU style better.
4334
4335 2006-09-20 Bob Rossi <bob@brasko.net>
4336
4337 * data/push.c (yyresult_get): Remove function.
4338 (YYPUSH_MORE): Add #define.
4339 (yypushparse): Modify return value.
4340
4341 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4342
4343 * stamp-h.in: Remove; no longer needed.
4344 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
4345 Remove config.h, config.hin, intl (no longer created).
4346 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
4347 stamp-h1.
4348
4349 Sync bootstrap from coreutils, as follows:
4350
4351 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
4352
4353 * bootstrap (symlink_to_gnulib): New function.
4354 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4355 to copies-of-gnulib.
4356 (cp_mark_as_generated, slurp, gnulib_files):
4357 Avoid making a copy if it's the same as the old version.
4358 (gnulib_files): Add support for this variable (used by Bison).
4359
4360 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4361
4362 * src/getargs.c (usage): Rework to use conventions similar to
4363 coreutils, to make translation a bit easier and the code a bit
4364 smaller. Problem reported by Tim Van Holder.
4365
4366 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4367
4368 Use some of gnulib's new modules, taken from coreutils.
4369
4370 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4371 * bootstrap.conf: New file.
4372 (gnulib_modules): Add configmake, inttypes, unistd.
4373 (XGETTEXT_OPTIONS): Add complain, complain_at,
4374 fatal, fatal_at, warn, warn_at, unexpected_end.
4375 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4376 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4377 (gl_EARLY): Add.
4378 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4379 (gl_INIT): Add
4380 (GNULIB_AUTOCONF_SNIPPET): Remove.
4381 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4382 the pickiest.
4383 * lib/.cvsignore: Add inttypes_.h.
4384 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4385 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4386 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4387 no-longer-necessary initializations.
4388 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4389 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4390 use the unistd module.
4391 * src/system.h: Likewise.
4392 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4393 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4394 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4395 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4396 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4397 * src/system.h: Include inttypes.h unconditionally, now that we
4398 use the inttypes module. Don't bother to include stdint.h, since
4399 inttypes.h now does that for us.
4400 (LOCALEDIR): Remove, now that we use the configmake module.
4401 * src/getargs.c: Include configmake.h.
4402 * src/main.c: Likewise.
4403 * src/output.c: Likewise.
4404 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4405 not from $abs_top_builddir, since config.h moved.
4406
4407
4408 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4409 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4410
4411 * src/parse-gram.y (symbol_declaration): Don't put statements
4412 before declarations; it's not portable to C89.
4413 * src/scan-code.l (handle_action_at): Likewise.
4414
4415 * src/scan-code.l: Always initialize braces_level; the old code
4416 left it uninitialized and therefore had undefined behavior.
4417
4418 Don't attempt to redefine 'assert', since it runs afoul of
4419 systems where standard headers (mistakenly) include <assert.h>.
4420 Instead, define and use our own alternative, called 'aver'.
4421 * src/reader.c: Don't include assert.h, since we no longer
4422 use assert.
4423 * src/scan-code.l: Likewise.
4424 * src/system.h (assert): Remove, replacing with....
4425 (aver): New function, taking a bool arg. All uses changed.
4426 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4427 not merely an integer.
4428
4429 2006-09-15 Bob Rossi <bob@brasko.net>
4430
4431 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4432 * data/c.m4 (YYPUSH): New.
4433 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4434 * src/getargs.c (push_parser): New var.
4435 * src/getargs.h (push_parser): New declaration.
4436 * src/output.c (prepare): Add macro insertion of `push_flag'.
4437 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4438 (prologue_declaration): Parse %push-parser.
4439 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4440 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4441 list of removed lines from the traces observed.
4442 (AT_CHECK_CALC_LALR): Added push parser tests.
4443
4444 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4445
4446 * NEWS: Version 2.3a.
4447 * configure.ac (AC_INIT): Likewise.
4448
4449 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4450 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4451 due to header ordering dependencies. I don't know why the #define
4452 was there.
4453
4454 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4455 runtime cost when YYDEBUG is not defined, and so that some tests
4456 that used to fail now work. Problem and initial suggestion by
4457 Paolo Bonzini.
4458 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4459 * data/glr.cc (b4_parser_class_name):
4460 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4461 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4462 (yydebug_) [YYDEBUG]: New member.
4463 (yycdebug_): Now defined only if YYDEBUG.
4464 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4465 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4466 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4467 if YYYDEBUG.
4468 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4469 Define only if YYDEBUG.
4470 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4471 set_debug_level.
4472 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4473 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4474 AT_CHECK_CALC_GLR_CC that are working now.
4475
4476 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4477
4478 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4479 We don't need them in glr.cc, and glr.c defines them.
4480 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4481 assumes that defining it to anything is the same as defining
4482 it to 1. Problem reported by Paolo Bonzini.
4483
4484 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4485
4486 * data/c.m4 (b4_null, b4_case): Define.
4487 * src/output.c (prepare_symbols): Use b4_null.
4488 (user_actions_output): Use b4_case.
4489
4490 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4491
4492 * data/glr.c (b4_shared_declarations): Put start-header first,
4493 before any #includes that we generate, so that feature-test
4494 macros work. Problem reported by Michael Deutschmann in
4495 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4496 * data/lalr1.cc: Likewise.
4497 * doc/bison.texinfo (Prologue): Document that feature-test macros
4498 should be defined before any Bison declarations.
4499 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4500 that depend on location.hh after, not before, Bison decls, since
4501 we now include location.hh after the first user prologue.
4502
4503 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4504 Sander Brandenburg in
4505 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4506 Also, fix minor white space and comment issues.
4507 (Prologue): Mention that it's better to define feature-test macros
4508 before Bison declarations. Problem reported by Michael Deutschmann.
4509
4510 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4511 by Jim Meyering.
4512 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4513 This adjusts to recent gnulib changes.
4514
4515 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4516
4517 Finish implementation of per-type %destructor/%printer. Discussed
4518 starting at
4519 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4520 and
4521 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4522 * NEWS (2.3+): Add a description of this feature to the default
4523 %destructor/%printer description.
4524 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4525 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4526 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4527 list node contains a semantic type.
4528 * src/symtab.c, src/symtab.h: Extend with a table that associates
4529 semantic types with their %destructor's and %printer's.
4530 (semantic_type_from_uniqstr, semantic_type_get,
4531 semantic_type_destructor_set, semantic_type_printer_set): New functions
4532 composing the public interface of that table.
4533 (symbol_destructor_get, symbol_destructor_location_get,
4534 symbol_printer_get, symbol_printer_location_get): If there's no
4535 per-symbol %destructor/%printer, look up the per-type before trying
4536 the default.
4537 * tests/actions.at (Per-type %printer and %destructor): New test case.
4538 * tests/input.at (Default %printer and %destructor redeclared):
4539 Extend to check that multiple occurrences of %symbol-default in a
4540 single %destructor/%printer declaration is an error.
4541 (Per-type %printer and %destructor redeclared, Unused values with
4542 per-type %destructor): New test cases.
4543
4544 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4545
4546 Require default %destructor/%printer to be declared using
4547 %symbol-default instead of an empty symbol list, and start working on
4548 new per-type %destructor/%printer. Discussed at
4549 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4550 * NEWS (2.3+): Add %symbol-default to example.
4551 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4552 (Table of Symbols): Add entry for %symbol-default.
4553 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4554 (generic_symlist, generic_symlist_item): New nonterminals for creating
4555 a list in which each item is a symbol, semantic type, or
4556 %symbol-default.
4557 (grammar_declaration): Use generic_symlist in %destructor and %printer
4558 declarations instead of symbols.1 or an empty list.
4559 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4560 for changes to symbol_list.
4561 * src/reader.c: Update for changes to symbol_list.
4562 * src/scan-code.l: Likewise.
4563 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4564 * src/symlist.c, src/symlist.h: Extend such that a list node may
4565 represent a semantic type or a %symbol-default in addition to just an
4566 ordinary symbol. Add switched functions for setting %destructor's and
4567 %printer's.
4568 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4569 %destructor/%printer declarations.
4570
4571 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4572
4573 Whether the default %destructor/%printer applies to a particular symbol
4574 isn't a question of whether the user *declares* that symbol (in %token,
4575 for example). It's a question of whether the user by any means
4576 *defines* the symbol at all (by simply using a char token, for
4577 example). $end is defined by Bison whereas any other token with token
4578 number 0 is defined by the user. The error token is always defined by
4579 Bison regardless of whether the user declares it with %token, but we
4580 may one day let the user define error as a nonterminal instead.
4581 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4582 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4583 the meaning of "user-defined".
4584 * tests/actions.at (Default %printer and %destructor for user-declared
4585 end token): Rename to...
4586 (Default %printer and %destructor for user-defined end token): ...
4587 this.
4588
4589 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4590 computation of whether to apply the default, don't maintain a list of
4591 every Bison-defined symbol. Instead, just check for a first character
4592 of '$', which a user symbol cannot have, and check for the error token.
4593
4594 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4595
4596 Don't apply the default %destructor or %printer to the error token,
4597 $undefined, or $accept. This change fits the general rule that the
4598 default %destructor and %printer are only for user-declared symbols,
4599 and it solves several difficulties that are described in the new test
4600 cases listed below.
4601 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4602 * tests/actions.at (Default %printer and %destructor are not for error
4603 or $undefined, Default %printer and %destructor are not for $accept):
4604 New test cases.
4605
4606 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4607
4608 Allow %start after the first rule.
4609 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4610 when parsing the first rule.
4611 (check_and_convert_grammar): Search for it here after all grammar
4612 declarations have been parsed. Skip midrules, which have dummy LHS
4613 nonterminals.
4614 * src/symtab.c (symbol_is_dummy): New function.
4615 * src/symtab.h (symbol_is_dummy): Declare it.
4616 * tests/input.at (%start after first rule): New test.
4617
4618 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4619
4620 Redo some of the previous commit: add back the ability to use
4621 non-aliased/undeclared string literals since it might be useful to
4622 those declaring %token-table.
4623 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4624 commit: don't worry about complaints from symbols_pack.
4625 * src/symtab.c (symbol_new, symbol_class_set,
4626 symbol_check_alias_consistency): Undo changes in previous commit: count
4627 each string literal as a new symbol and token, assign it a symbol
4628 number, and don't complain about non-aliased string literals.
4629 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4630 and token counts but does still set aliased tokens to the same number,
4631 symbol_pack_processor now leaves empty slots in the symbols array.
4632 Remove those slots.
4633 * tests/regression.at (Undeclared string literal): Remove test case
4634 added in previous commit since non-aliased string literals are allowed
4635 again.
4636 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4637 remove unnecessary string literal declarations.
4638 * tests/sets.at (Firsts): Likewise.
4639
4640 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4641
4642 Don't allow an undeclared string literal, but allow a string literal to
4643 be used before its declaration.
4644 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4645 symbols_pack complained.
4646 * src/symtab.c (symbol_new): Don't count a string literal as a new
4647 symbol.
4648 (symbol_class_set): Don't count a string literal as a new token, and
4649 don't assign it a symbol number since symbol_make_alias does that.
4650 (symbol_make_alias): It's not necessary to decrement the symbol and
4651 token counts anymore. Don't assume that an alias declaration occurs
4652 before any uses of the identifier or string, and thus don't assert that
4653 one of them has the highest symbol number so far.
4654 (symbol_check_alias_consistency): Complain if there's a string literal
4655 that wasn't declared as an alias.
4656 (symbols_pack): Bail if symbol_check_alias_consistency failed since
4657 symbol_pack asserts that every token has been assigned a symbol number
4658 although undeclared string literals have not.
4659 * tests/regression.at (String alias declared after use, Undeclared
4660 string literal): New test cases.
4661 (Characters Escapes, Web2c Actions): Declare string literals as
4662 aliases.
4663 * tests/sets.at (Firsts): Likewise.
4664
4665 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
4666
4667 In the grammar scanner, STRING_FINISH unclosed constructs and return
4668 them to the parser in order to improve error messages.
4669 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
4670 SC_BRACED_CODE, SC_PROLOGUE): Implement.
4671 * tests/input.at (Unclosed constructs): New test case.
4672 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
4673 seen.
4674
4675 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
4676 unused global.
4677
4678 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
4679
4680 Handle string aliases for character tokens correctly.
4681 * src/symtab.c (symbol_user_token_number_set): If the token has an
4682 alias, check and set its alias's user token number instead of its own,
4683 which is set to indicate the alias. Previously, every occurrence of
4684 the character token in the grammar overwrote that alias indicator with
4685 the character code.
4686 * tests/input.at (String aliases for character tokens): New test.
4687
4688 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
4689
4690 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
4691
4692 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
4693
4694 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
4695 to prevent failures when building on older platforms.
4696 Check for autopoint failure.
4697 Set XGETTEXT_OPTIONS to values that check for C format strings,
4698 so that translators are warned about them (this also helps
4699 prevent core dumps).
4700
4701 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
4702 function, since it simplifies our code a bit.
4703
4704 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
4705 rather than -W, so we don't get bogus warnings about sign comparisons.
4706 Add -Wpointer-arith, since that warning is useful (it reports code
4707 that does not conform to C89 and that some compilers reject).
4708 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
4709 since it's no longer needed.
4710
4711 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
4712
4713 Clean up scanners a bit.
4714 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
4715 definitions so gcc won't warn when obstack_for_string is unused.
4716 * src/scan-code.l: config.h and system.h are already #include'd by
4717 scan-code-c.c, so get rid of them here.
4718 * src/scan-gram.l: Likewise.
4719 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
4720 definitions rather than duplicating the rest of it.
4721 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
4722
4723 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
4724
4725 Suppress signed/unsigned comparison warnings for yycheck.
4726 * data/c.m4 (b4_safest_int_type): New macro.
4727 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
4728 a signed int type, cast it to b4_safest_int_type first.
4729 * data/yacc.c: Likewise.
4730 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
4731 also overwritten.
4732
4733 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
4734
4735 * doc/bison.texinfo: Fix some typos.
4736
4737 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
4738
4739 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
4740 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
4741
4742 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
4743 the latest gnulib does this a different way.
4744 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
4745 translation was patched, so stop omitting it.
4746
4747 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4748
4749 Enable declaration of default %printer/%destructor. Make the parser
4750 use these for all user-declared grammar symbols for which the user does
4751 not declare a specific %printer/%destructor. Thus, the parser uses it
4752 for token 0 if the user declares it but not if Bison generates it as
4753 $end. Discussed starting at
4754 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
4755 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
4756 and
4757 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
4758 * NEWS (2.3+): Mention.
4759 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
4760 declare a %destructor for a mid-rule's semantic value. It's just
4761 impossible to declare one specific to it.
4762 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
4763 code. Describe default %destructor form.
4764 * src/parse-gram.y (grammar_declaration): Parse default
4765 %printer/%destructor declarations.
4766 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
4767 and symbol_destructor_location_get rather than accessing the destructor
4768 and destructor_location members of struct symbol.
4769 (symbol_printers_output): Likewise but for %printer's.
4770 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
4771 again.
4772 * src/symtab.c (default_destructor, default_destructor_location,
4773 default_printer, default_printer_location): New static global
4774 variables to record the default %destructor and %printer.
4775 (symbol_destructor_get, symbol_destructor_location_get,
4776 symbol_printer_get, symbol_printer_location_get): New functions to
4777 compute the appropriate %destructor and %printer for a symbol.
4778 (default_destructor_set, default_printer_set): New functions to set the
4779 default %destructor and %printer.
4780 * src/symtab.h: Prototype all those new functions.
4781 * tests/actions.at (Default %printer and %destructor): New test to
4782 check that the right %printer and %destructor are called, that they're
4783 not called for $end, and that $$ and @$ work correctly.
4784 (Default %printer and %destructor for user-declared end token): New
4785 test to check that the default %printer and %destructor are called for
4786 a user-declared end token.
4787 * tests/input.at (Default %printer and %destructor redeclared, Unused
4788 values with default %destructor): New tests to check related grammar
4789 warnings and errors.
4790
4791 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
4792
4793 Clean up handling of %destructor for the end token (token 0).
4794 Discussed starting at
4795 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
4796 and
4797 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
4798
4799 Make the skeletons consistent in how they pop the end token and invoke
4800 its %destructor.
4801 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
4802 state, which has token number 0, since this would invoke the
4803 %destructor for the end token.
4804 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
4805 until after shifting the end token, or else it won't be popped.
4806 * data/yacc.c (yyparse): Likewise.
4807
4808 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
4809 it's the end token. Upon termination, destroy an unshifted lookahead
4810 even when it's the end token.
4811 * data/lalr1.cc (yy::parser::parse): Likewise.
4812 * data/yacc.c (yyparse): Likewise.
4813
4814 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
4815 value warnings for the end token when the user gives the end token a
4816 %destructor.
4817
4818 * tests/actions.at (Printers and Destructors): Test all the above.
4819
4820 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
4821
4822 Update to latest gnulib and gettext versions.
4823 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
4824 Add fopen-safer.
4825 (gnulib_files): Add m4/warning.m4. Don't worry about files
4826 overwritten by autopoint.
4827 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
4828 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
4829 rejects them.
4830 Don't use autoreconf; instead, invoke autopoint etc. by hand,
4831 so that we can remove the intl files at a better time.
4832 (intl_files_to_remove): Remove aclocal.m4, since it gets
4833 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
4834 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
4835 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
4836 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
4837 Remove datarootdir hack; no longer needed.
4838 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
4839 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
4840 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
4841 strdup.h.
4842 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
4843 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
4844
4845 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
4846
4847 * bootstrap: Adjust to today's change to gnulib-tool by invoking
4848 it with --assume-autoconf='latest-stable'.
4849
4850 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
4851
4852 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
4853 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
4854 YYSTYPE' and `{'.
4855 * src/muscle_tab.h (muscle_grow): Replace the header comments with
4856 those from muscle_tab.c since the old ones are misleading.
4857
4858 2006-07-13 Akim Demaille <akim@epita.fr>
4859
4860 Support %define "KEY" {VALUE}.
4861 * src/scan-code.h, src/scan-code.l (translate_action)
4862 (translate_rule_action, translate_symbol_action, translate_code):
4863 Return char *, not const char *.
4864 * src/parse-gram.y (declaration): Rename as...
4865 (prologue_declaration): this.
4866 (string_content): Remove this nonterminal, use STRING.
4867 (braceless, content, content.opt): New nonterminal.
4868 Use them.
4869 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
4870 as value.
4871 * src/scan-gram.l (getargs.h): Don't include it.
4872
4873 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
4874
4875 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
4876 rather than a for-loop that declares a local bool variable. This
4877 should work around a compatibility problem with a Cray x1e C++
4878 compiler reported by Hung Nguyen in
4879 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
4880 The for-loop was introduced in the 2004-11-17 change but I don't
4881 know why it was needed.
4882
4883 2006-07-12 Akim Demaille <akim@epita.fr>
4884
4885 * data/c.m4: Comment changes.
4886
4887 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
4888
4889 * src/complain.c (error_message, ERROR_MESSAGE): New.
4890 To factor...
4891 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
4892 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
4893
4894 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4895
4896 * NEWS: Instead of %union, you can define and use your own union type
4897 YYSTYPE if your grammar contains at least one <type> tag.
4898 Your YYSTYPE need not be a macro; it can be a typedef.
4899 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
4900 (Union Decl, Decl Summary): Document this.
4901 * data/glr.c (YYSTYPE): Implement this.
4902 * data/glr.cc (YYSTYPE): Likewise.
4903 * data/lalr1.cc (YYSTYPE): Likewise.
4904 * data/yacc.c (YYSTYPE): Likewise.
4905 * src/output.c (prepare): Output tag_seen_flag.
4906 * src/parse-gram.y (declaration, grammar_declaration):
4907 Use 'union_seen' rather than 'typed' to determine whether
4908 %union has been seen, since grammars can now be typed without
4909 %union.
4910 (symbol_declaration, type.opt, symbol_def):
4911 Keep track of whether a tag has been seen.
4912 * src/reader.c (union_seen, tag_seen): New vars.
4913 (typed): remove.
4914 * src/reader.h (union_seen, tag_seen, typed): Likewise.
4915 * src/scan-code.l (untyped_var_seen): New variable.
4916 (handle_action_dollar): Adjust to above changes.
4917 (handle_action_dollar, handle_action_at):
4918 Improve overflow checking for outlandish numbers.
4919 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
4920 avoid new diagnostics generated by above changes.
4921 * tests/regression.at (YYSTYPE typedef): Add test to check
4922 for type tags without %union.
4923
4924 * src/symlist.c (symbol_list_length): Return int, not unsigned
4925 int, since callers expect int. This may need to get revisited
4926 once we have proper integer overflow checking.
4927
4928 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
4929 object is now static.
4930
4931 * src/getargs.c (flags_argmatch): Return void, not int,
4932 to pacify ./configure --enable-gcc-warnings.
4933
4934 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
4935 since last_string is already defined to FLEX_PREFIX (last_string).
4936
4937 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4938
4939 Implement --warnings/-W.
4940 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
4941 replaced by...
4942 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
4943 Adjust callers.
4944 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
4945 (warnings_args, warnings_types): New.
4946 (getargs, short_options, long_options): Accept -W/--warnings.
4947 Sort the options by alphabetical order, upper case letter right
4948 before its lower case.
4949
4950 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
4951
4952 Change %merge result type clash warnings to errors. Discussed at
4953 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
4954 * src/reader.c (record_merge_function_type): Use complain_at.
4955 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
4956 declared later): Update test case results.
4957
4958 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
4959
4960 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
4961 to be in alphabetical order.
4962 (trace_args): Spelling fixes.
4963
4964 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
4965
4966 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
4967 so they don't collide with user-defined macros.
4968 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
4969 this was never guaranteed, and now that we're using gnulib stdint,
4970 which defines int_fast16_t to long int, the problem is exposed.
4971
4972 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
4973
4974 * data/c.m4 (b4_basename): Simplify a bit, since we don't
4975 need the full POSIX semantics (and weren't implementing them
4976 anyway).
4977
4978 Adjust to Autoconf 2.60 and today's gnulib.
4979 * bootstrap (gnulib_modules): Add stdint.
4980 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
4981 no longer copies it.
4982 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
4983 since stdint needs the former and wcwidth (which is now required
4984 by mbswidth) needs the latter.
4985 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
4986 work around a compatibility glitch between gettext 0.14.6 and
4987 Autoconf 2.60.
4988 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
4989 Do not check for uintptr_t, since new stdint module does the right
4990 thing.
4991 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
4992 Add stdint.h, stdint_.h, wcwidth.h.
4993 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
4994 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
4995 stdint.m4, wchar_t.m4, wcwidth.m4.
4996 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
4997 usual order for ../lib/*.h files.
4998 (file_name_split): Use last_component, not base_name, to adjust
4999 to gnulib changes.
5000 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5001 for ../lib/*.h files.
5002 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5003 Define unconditionally, since we now assume the stdint module.
5004 * src/scan-skel.l: Include <dirname.h>.
5005 (BASE_QPUTS): Use last_component, not base_name.
5006 * src/system.h: Include <unlocked-io.h> in the usual order
5007 for ../lib/*.h files. Include <stdint.h> unconditionally,
5008 since we now use the stdint module.
5009 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5010 HAVE_UINTPTR_T, since we now use the stdint module.
5011 (base_name): Remove decl, since files now include <dirname.h>
5012 to get the decl.
5013
5014 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5015
5016 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5017 New, default to 1.
5018 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5019 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5020 default.
5021 * tests/calc.at: Adjust.
5022
5023 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5024
5025 * data/c.m4 (b4_basename): New.
5026 (b4_syncline): Also output the location of its invocation (from
5027 the skeleton).
5028 (b4_user_action, b4_define_user_action, b4_user_actions)
5029 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5030 (b4_user_stype): New.
5031 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5032
5033 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5034
5035 In the grammar file, the first column is 1 not 0 on the first line as
5036 on every other line.
5037 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5038 * tests/input.at (Torturing the Scanner): Update output.
5039
5040 * src/scan-gram.l (scanner_cursor): Declare it static.
5041
5042 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5043
5044 In warnings, say "previous declaration" rather than "first
5045 declaration".
5046 * src/symtab.c (redeclaration): Do that here.
5047 * src/reader.c (record_merge_function_type): In the case of a result
5048 type clash, report the previous declaration rather than the very first
5049 one in the grammar file.
5050 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5051 declared later): Add a third declaration to check this behavior.
5052 * tests/input.at (Incompatible Aliases): Update output.
5053
5054 2006-06-27 Akim Demaille <akim@epita.fr>
5055
5056 * doc/Doxyfile.in: New.
5057 * doc/Makefile.am: Use it.
5058 * src/lalr.h, src/symtab.h: Initial doxygenation.
5059
5060 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5061
5062 Don't miss %merge result type warnings just because the LHS types are
5063 declared after the %merge. This continues the effort of the previous
5064 patch.
5065 * src/reader.c (get_merge_function): Don't set the merger type yet.
5066 (record_merge_function_type): New function for setting the merger type
5067 and checking for clashes.
5068 (grammar_current_rule_merge_set): Set the location of the %merge for
5069 the current rule.
5070 (packgram): Invoke record_merge_function_type for each rule now that
5071 all symbol type declarations have been parsed.
5072 * src/reader.h (merger_list.type_declaration_location): New member
5073 storing the location of the first %merge from which the type for this
5074 merging function was derived.
5075 * src/symlist.h (symbol_list.merger_declaration_location): New member
5076 storing the location of a rule's %merge, if any.
5077 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5078 declared later): New test to catch the error fixed by the above patch.
5079
5080 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5081
5082 Get action warnings (grammar_rule_check) right even when symbol
5083 declarations appear after the rules. Discussed at
5084 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5085 and
5086 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5087 Don't mistake the type of $$ in a midrule to be that of its parent
5088 rule's $$.
5089 * src/reader.c (grammar_current_rule_end): Don't invoke
5090 grammar_rule_check yet since not all symbol declarations may have been
5091 parsed yet.
5092 (grammar_midrule_action): Likewise.
5093 Don't record whether the midrule's $$ has been used yet since actions
5094 haven't been translated yet.
5095 Record the midrule's parent rule and its RHS index within the parent
5096 rule.
5097 (grammar_current_rule_action_append): Don't translate the action yet
5098 since not all symbol declarations may have been parsed yet and, thus,
5099 warnings about types for $$, $n, @$, and @n can't be reported yet.
5100 (packgram): Translate the action and invoke grammar_rule_check now that
5101 all symbol declarations have been parsed.
5102 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5103 after parsing the entire grammar file, the symbol list here in the case
5104 of a midrule is actually the midrule's empty RHS, so reference its
5105 parent rule's RHS where necessary.
5106 On the other hand, now that you can already know it's a midrule, you
5107 aren't forced to think $$ has the same type as its parent rule's $$.
5108 (handle_action_at): In the case of a midrule, reference the parent rule
5109 where necessary.
5110 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5111 members.
5112 (symbol_list_length): Now that this is invoked after all rules have
5113 been parsed, a NULL symbol (rather than a NULL symbol list node)
5114 terminates a rule. symbol_list_print already does this correctly.
5115 * src/symlist.h (symbol_list.midrule_parent_rule,
5116 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5117 remember their relationships with their parents.
5118 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5119 fixed by the above patch.
5120 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5121 implementing...
5122 (Unused values): ... this old test case and...
5123 (Unused values before symbol declarations): ... this new test case.
5124 This one is the same as `Unused values' except that all symbol
5125 declarations appear after the rules in order to catch the rest of the
5126 errors fixed by the above patch.
5127
5128 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5129
5130 More cleanup.
5131 * src/reader.c (current_rule): Declare it static since it's no longer
5132 used outside this file.
5133 (grammar_current_rule_action_append): Remove redundant arguments from
5134 translate_rule_action invocation.
5135 * src/reader.h (current_rule): Remove this unused extern.
5136 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5137 * src/scan-code.l (translate_rule_action): Likewise.
5138
5139 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5140
5141 Clean up yesterday's patch.
5142 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5143 to...
5144 * src/reader.c (grammar_current_rule_action_append): ... here for
5145 consistency with grammar_current_rule_symbol_append.
5146 * tests/regression.at (Braced code in declaration in rules section):
5147 Make yyerror and yylex static as usual.
5148
5149 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5150
5151 Fix bug that mistakes braced code in a declaration in the rules section
5152 to be a rule action. Mentioned at
5153 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5154 * src/scan-gram.l: Move midrule action detection from the start of the
5155 scanning of any braced code to...
5156 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5157 action. For readability, use $2 and @2 rather than the equivalent
5158 global variables.
5159 * tests/regression.at (Braced code in declaration in rules section):
5160 New test to catch the error fixed by the above patch.
5161
5162 Work on code readability some.
5163 * src/scan-code.l (current_rule): Get rid of this misleading and
5164 redundant declaration: it's actually extern'ed in reader.h.
5165 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5166 translate_action): Add a rule argument and use it instead of the global
5167 current_rule.
5168 (translate_rule_action): This already receives current_rule through an
5169 argument, so pass it on to translate_action instead of assigning
5170 current_rule to current_rule.
5171 (translate_symbol_action, translate_code): Pass rule = NULL to
5172 translate_action.
5173
5174 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5175
5176 Rename %before-definitions to %start-header and %after-definitions to
5177 %end-header. Don't use these declarations to separate pre-prologue
5178 blocks from post-prologue blocks. Add new order-independent
5179 declarations %before-header and %after-header as alternatives to the
5180 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5181 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5182 * NEWS (2.3+): Update for these changes.
5183 * data/glr.c (b4_before_definitions): Update to...
5184 (b4_start_header): ... this.
5185 (b4_after_definitions): Update to...
5186 (b4_end_header): ... this.
5187 * data/glr.cc: Likewise.
5188 * data/lalr1.cc: Likewise.
5189 * data/yacc.c: Likewise.
5190 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5191 prologue blocks with %*-header declarations.
5192 (Calc++ Parser): Likewise.
5193 (Decl Summary): Update names.
5194 (Table of Symbols): Update description.
5195 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5196 (PERCENT_END_HEADER): ... this.
5197 (PERCENT_BEFORE_DEFINITIONS): Update to...
5198 (PERCENT_START_HEADER): ... this.
5199 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5200 (declaration): Update token names and m4 macro names.
5201 When parsing %end-header and %start-header, invoke translate_code
5202 before muscle_code_grow, and no longer set global booleans to remember
5203 whether these declarations have been seen.
5204 Parse new %after-header and %before-header.
5205 * src/reader.c (before_definitions, after_definitions): Remove.
5206 (prologue_augment): Accept a new bool argument to specify whether to
5207 augment the pre-prologue or post-prologue.
5208 * src/reader.h (before_definitions, after_definitions): Remove these
5209 extern's.
5210 (prologue_augment): Add new bool argument.
5211 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
5212 (PERCENT_END_HEADER): ... this.
5213 (PERCENT_BEFORE_DEFINITIONS): Update to...
5214 (PERCENT_START_HEADER): ... this.
5215 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5216 * tests/actions.at (Printers and Destructors): Update names.
5217
5218 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5219
5220 Add comparison operators for C++ location classes. Discussed at
5221 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5222 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5223 declaration indicating whether filename_type has an operator==. If
5224 filename_type is `std::string', it defaults to `1', `0' otherwise.
5225 * data/location.cc: Iff b4_define_location_comparison is `1', add
5226 operator== and operator!= for class position and for class location.
5227
5228 Some minor fixes.
5229 * src/scan-action.l: Remove unused file.
5230 * src/symtab.c (symbol_printer_set): Use printer_location not
5231 destructor_location.
5232 * src/symtab.h (struct symbol): Replace incorrect source comment for
5233 printer members.
5234 * tests/input.at (Incompatible Aliases): Update output with correct
5235 printer location.
5236
5237 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5238
5239 Don't put the pre-prologue in the header file. For the yacc.c code
5240 file and the glr.c header and code files, move the pre-prologue before
5241 the token definitions. Add new %before-definitions and
5242 %after-definitions to declare code that will go in both the header file
5243 and code file. Discussed at
5244 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5245 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5246 and
5247 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5248 * NEWS (2.3+): Describe these changes.
5249 * data/glr.c (b4_pre_prologue): Move from within to before...
5250 (b4_shared_declarations): ... this.
5251 Add new b4_before_definitions before b4_token_enums.
5252 Add new b4_after_definitions at the end.
5253 * data/glr.cc (b4_pre_prologue): Replace with...
5254 (b4_before_definitions): ... this in the header file.
5255 (b4_after_definitions): New near the end of the header file.
5256 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5257 code file right before including the header file.
5258 (b4_before_definitions): New in the previous position of
5259 b4_pre_prologue in the header file.
5260 (b4_after_definitions): New near the end of the header file.
5261 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5262 (b4_token_enums_defines): In the code file, move to right before
5263 YYSTYPE for consistency with the header file.
5264 (b4_before_definitions): New right before b4_token_enums_defines in
5265 both the header and code file.
5266 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5267 header and code file.
5268 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5269 of prologues for %union dependencies.
5270 (Decl Summary): In %defines description, mention the effect of
5271 %before-definitions and %after-definitions on the header file.
5272 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5273 than in the pre-prologue so that make check succeeds.
5274 (Table of Symbols): Add entries for %before-definitions and
5275 %after-definitions.
5276 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5277 %before-definitions.
5278 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5279 (declaration): Parse those declarations and append to
5280 b4_before_definitions and b4_after_definitions, respectively.
5281 * src/reader.c (before_definitions, after_definitions): New bools to
5282 track whether those declarations have been seen.
5283 (prologue_augment): Add to the post-prologue if %union,
5284 %before-definitions, or %after-definitions has been seen.
5285 * src/reader.h (before_definitions, after_definitions): New extern's.
5286 * src/scan-gram.l: Scan the new declarations.
5287 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5288 prologue block in a %before-definitions or a %after-definitions based
5289 on whether the %union is declared.
5290 * tests/regression.at (Early token definitions with --yacc, Early token
5291 definitions without --yacc): Move tests for token definitions into the
5292 post-prologue since token names are no longer defined in the
5293 pre-prologue.
5294
5295 2006-06-20 Akim Demaille <akim@epita.fr>
5296
5297 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5298 (symbol_get): Use it.
5299 * src/parse-gram.y: Use it.
5300
5301 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5302
5303 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5304 build succeeds when configured with --enable-gcc-warnings.
5305
5306 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5307
5308 * src/parse-gram.y (char_name): New function.
5309 (CHAR, STRING, string_content): For %printer, properly escape.
5310 (ID): Prefer fputs to fprintf.
5311 (id): Reindent to be consistent with other rules.
5312 Properly quote char.
5313
5314 The Translation Project changed its way of publishing translations
5315 to maintainers. I haven't received any responses to my request
5316 for supporting the old way, or for documenting the new way. I
5317 have modified 'bootstrap' to use screen scraping
5318 (in this case, HTML scraping). This is unreliable and inelegant,
5319 but I don't see any better way. Yuck.
5320 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5321 (get_translations): New function, which uses HTML scraping to
5322 deduce locations of latest translations.
5323 Use this function to grab both bison and bison-runtime .po files.
5324 Don't bother priming the pump for the runtime-po domain any more,
5325 as it's now translated better than bison is.
5326
5327 2006-06-19 Akim Demaille <akim@epita.fr>
5328
5329 * src/scan-gram.l: No longer "parse" things after `%union' until
5330 `{'. Rather, return a single "%union" token.
5331 No longer make symbols: return strings, and leave the conversion
5332 to symbols to the parser.
5333 (SC_PRE_CODE, token_type): Remove.
5334 * src/parse-gram.y (%union): New field `character'.
5335 Sort tokens.
5336 (CHAR): New token.
5337 (ID, ID_COLON): Now that the scanner no longer makes them
5338 identifiers, adjust all uses to invoke symbol_get.
5339 (id_colon): New, wraps the conversion from string to symbol.
5340 (%union): Accept a possible union_name.
5341 (symbol): Now can be a char.
5342 * data/c.m4 (b4_union_name): Leave a default value.
5343 * data/glr.c, data/yacc.c: Use it.
5344
5345 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5346
5347 For associating token numbers with token names for "yacc.c", don't use
5348 #define statements unless `--yacc' is specified; always use enum
5349 yytokentype. Most important discussions start at:
5350 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5351 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5352 and
5353 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5354 * NEWS (2.3+): Mention.
5355 * data/c.m4 (b4_yacc_if): New.
5356 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5357 token #define's.
5358 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5359 on token name definitions.
5360 * src/getargs.c (usage): Capitalize `Yacc' in English.
5361 * src/output.c (prepare): Define b4_yacc_flag.
5362 * tests/regression.at (Early token definitions): Test that tokens names
5363 are defined before the pre-prologue not just before the post-prologue.
5364 Remove this test case and copy to...
5365 (Early token definitions with --yacc): ... this to test #define's.
5366 (Early token definitions without --yacc): ... and this to test enums.
5367
5368 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5369
5370 * NEWS: Reword the post-2.3 change to not be so optimistic about
5371 removing the old "look-ahead" spelling.
5372 Update previous look-ahead/lookahead change reports.
5373 * REFERENCES: look-ahead -> lookahead (since that's
5374 what he actually wrote).
5375 * doc/refcard.tex: look ahead -> lookahead,
5376 look-ahead -> lookahead
5377
5378 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5379
5380 For consistency, use `lookahead' instead of `look-ahead' or
5381 `look_ahead'. Discussed starting at
5382 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
5383 and then at
5384 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.
5385 * NEWS: For the next release, note the change to `--report'.
5386 * TODO, doc/bison.1: Update English.
5387 * doc/bison.texinfo: Update English.
5388 (Understanding Your Parser, Bison Options): Document as
5389 `--report=lookahead' rather than `--report=look-ahead'.
5390 * src/conflicts.c: Update English in comments.
5391 (lookahead_set): Rename from look_ahead_set.
5392 (flush_reduce): Rename argument look_ahead_tokens to lookahead_tokens.
5393 (resolve_sr_conflict): Rename local look_ahead_tokens to
5394 lookahead_tokens, and update other uses.
5395 (flush_shift, set_conflicts, conflicts_solve, count_sr_conflicts,
5396 count_rr_conflicts, conflicts_free): Update uses.

5454
5455 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
5456
5457 * TODO: Add request from Nelson H. F. Beebe to be able to install
5458 Bison without installing the yacc script.
5459
5460 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5461
5462 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5463 and yytext if they're already #define'd.
5464 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5465 * src/scan-code-c.c: ... here.
5466 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5467 <config.h>.
5468
5469 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5470
5471 Get Bison to build again when configured with --enable-gcc-warnings.
5472 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5473 missing #include's.
5474 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5475 loc argument as it shadows a global.
5476 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5477 invocation.

5480
5481 2006-06-07 Akim Demaille <akim@epita.fr>
5482

5484 to...
5485 * src/scan-code.l: here.
5486 * tests/input.at (Torturing the Scanner): Fix another location
5487 error.
5488
5489 2006-06-07 Akim Demaille <akim@epita.fr>
5490
5491 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5492
5493 2006-06-06 Akim Demaille <akim@epita.fr>
5494
5495 Extract the parsing of user actions from the grammar scanner.
5496 As a consequence, the relation between the grammar scanner and
5497 parser is much simpler. We can also split "composite tokens" back
5498 into simple tokens.
5499 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5500 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5501 rename as...
5502 * src/location.h, src/location.c (add_column_width)
5503 (location_compute): these.
5504 Fix the column count: the initial column is 0.
5505 (location_print): Be robust to ending column being 0.
5506 * src/location.h (boundary_set): New.
5507 * src/main.c: Adjust to scanner_free being renamed as
5508 gram_scanner_free.
5509 * src/output.c: Include scan-code.h.
5510 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5511 Use boundary_set.
5512 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5513 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5514 which is now, again, a separate token.
5515 Adjust all dependencies.
5516 Whereever actions with $ and @ are used, use translate_code.
5517 (action): Remove this nonterminal which is now useless.
5518 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5519 (grammar_current_rule_action_append): Use translate_code.
5520 (packgram): Bound check ruleno, itemno, and rule_length.
5521 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
5522 (last_string, last_braced_code_loc, max_left_semantic_context)
5523 (scanner_initialize, scanner_free, scanner_last_string_free)
5524 (gram_out, gram_lineno, YY_DECL_): Move to...
5525 * src/scan-gram.h: this new file.
5526 (YY_DECL): Rename as...
5527 (GRAM_DECL): this.
5528 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5529 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5530 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5531 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5532 Move these declarations, and...
5533 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5534 these to...
5535 * src/flex-scanner.h: this new file.
5536 * src/scan-gram.l (rule_length, rule_length_overflow)
5537 (increment_rule_length): Remove.
5538 (last_braced_code_loc): Rename as...
5539 (gram_last_braced_code_loc): this.
5540 Adjust to the changes of the parser.
5541 Move all the handling of $ and @ into...
5542 * src/scan-code.l: here.
5543 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5544 (handle_action_dollar, handle_action_at): Move to...
5545 * src/scan-code.l: here.
5546 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
5547 scan-code.h, scan-code-c.c, scan-gram.h.
5548 (EXTRA_bison_SOURCES): Add scan-code.l.
5549 (BUILT_SOURCES): Add scan-code.c.
5550 (yacc): Be robust to white spaces.

5553 * tests/regression.at: Adjust the column numbers.
5554 * tests/regression.at: Adjust the error message.
5555
5556 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5557
5558 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5559 Use Akim's wording from
5560 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5561
5562 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5563
5564 Between Bison releases, manually append `+' to the previous Bison
5565 release number, and use that as a signal to automatically print the
5566 ChangeLog's CVS Id keyword from --version. Discussed starting at
5567 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5568 * ChangeLog: Add Id header.
5569 * configure.ac (AC_INIT): Append `+' to `2.3'.
5570 * src/.cvsignore: Add revision.c.
5571 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5572 (BUILT_SOURCES): Add revision.c.
5573 (revision.c): New target rule. This file defines a new global variable
5574 named revision. It initializes it with either the Id from ChangeLog
5575 or, if VERSION doesn't contain `+', with the empty string.
5576 * src/getargs.c (version): Print the value of revision.
5577 * src/revision.h: Extern revision.
5578
5579 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5580
5581 * NEWS: Version 2.3.
5582 * configure.ac (AC_INIT): Likewise.
5583
5584 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5585
5586 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5587 with no arguments, not as an object-like macro. This is for
5588 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5589 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5590 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5591 Document this.
5592
5593 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5594
5595 * src/getargs.c (usage): Back out yesterday's modification of the
5596 --help output so that we don't have to wait for translation before
5597 releasing 2.3.
5598
5599 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5600
5601 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5602 Problem reported by Akim Demaille.
5603
5604 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5605
5606 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5607
5608 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5609
5610 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5611 generated source code. Problem reported by Frans Englich in
5612 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5613
5614 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5615
5616 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5617 shell, not within 'make', so that 'make' by an ordinary builder
5618 (using GNU make) does not worry about configuring gzip. This also
5619 works around a bug reported independently by Keith Thompson and by
5620 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5621 stderr rather than stdout, messing up the build logs.
5622
5623 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5624
5625 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5626 to make sure that YYID will never be unused. This fixes a 'make
5627 maintainer-check' failure caused by the recent changes to the 'Trivial
5628 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5629 not used.
5630 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5631
5632 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5633
5634 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5635 state before an empty RHS is always resolved here. Only the location
5636 of that state is guaranteed to be resolved, and that's enough. This
5637 fixes the remaining bug reported by Derek M. Jones in
5638 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5639 * tests/glr-regression.at (Uninitialized location when reporting
5640 ambiguity): Test the above case.
5641 Also, the embedded comments in this test case claim it checks the case
5642 of an empty RHS that has inherited the initial location. However, the
5643 corresponding LHS was already resolved, so yyresolveLocations didn't
5644 actually have reason to modify it. Fix this by forcing
5645 nondeterministic operation at the beginning of the parse.
5646
5647 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
5648
5649 * data/c.m4 (b4_yy_symbol_print_generate):
5650 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
5651 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
5652 of the bugs reported today by Derek M Jones in
5653 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5654 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
5655 defined to be a type name without parens or brackets.
5656 (Location Type): Similarly for YYLTYPE.
5657 * tests/regression.at (Trivial grammars): Put in a test for this
5658 bug that will be caught by 'make maintainer-check' (though not,
5659 alas, by 'make check' unless your compiler is picky).
5660
5661 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
5662
5663 * NEWS: Version 2.2.
5664 * configure.ac (AC_INIT): Likewise.
5665
5666 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
5667
5668 * data/glr.c (yyreportTree): Make room in yystates for the state
5669 preceding the RHS. This fixes the segmentation fault reported by Derek
5670 M. Jones in
5671 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
5672 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
5673 to the user. Reported for yyreportTree by Derek M. Jones later in the
5674 same thread.
5675 * THANKS: Add Derek M. Jones.
5676 Update my email address.
5677 Fix typo in Steve Murphy's name.
5678
5679 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
5680
5681 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
5682 checking against YYLAST that caused the parser to miss a potential
5683 alternative in its diagnostic.
5684 Problem reported by Maria Jose Moron Fernandez in
5685 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
5686 * data/lalr1.cc (yysyntax_error_): Likewise.
5687 * data/yacc.c (yysyntax_error): Likewise.
5688 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
5689 tokens, in case we run into an older C compiler.
5690 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
5691 Use them to check for the off-by-one error fixed above.
5692
5693 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
5694 YYSIZE_T, not size_t.
5695 * tests/regression.at (Trivial grammars): New test, to catch
5696 the error fixed by the above patch.
5697
5698 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5699
5700 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
5701 scheme.
5702 Reported by Steve Murphy.
5703
5704 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5705
5706 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
5707 * data/glr.cc: b4_location_flag is now b4_locations_flag.
5708
5709 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5710
5711 Implement --trace=m4.
5712 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
5713 * src/output.c (output_skeleton): When set, pass -dV to m4.
5714
5715 Factor the handling of flags in m4.
5716 * src/output.c (prepare): Rename the muscle names debug, defines,
5717 error_verbose to debug_flag, defines_flag, error_verbose_flag.
5718 * data/c.m4: Adjust.
5719 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
5720 Use b4_define_flag_if to define other b4_FLAG_if macros.
5721 (b4_location_if): As a consequence, rename as...
5722 (b4_locations_if): this, for consistency.
5723 Adjust all the skeletons.
5724
5725 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
5726
5727 * etc/bench.pm: Shorten bench names.

5731 * src/output.h, src/output.c (error_verbose): Move to...
5732 * src/getargs.h, src/getargs.c: here.
5733 Sort the flags.
5734 Adjust dependencies.
5735
5736 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
5737
5738 * data/c.m4 (b4_copyright): Put the special exception for Bison
5739 skeletons here, so we don't have to put it in each skeleton. All
5740 uses changed. Suggested by Akim Demaille. Also, wrap the
5741 copyright notice, in case it is longer than 80 columns. Replace
5742 comma by newline after title.
5743
5744 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
5745
5746 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
5747 incompatibility, not a bug. Mention that it wasn't fixed as of
5748 flex 2.5.33.
5749
5750 2006-05-11 Akim Demaille <akim@lrde.epita.fr>

5759 with the member "token".
5760 Reported by Martin Nylin.
5761
5762 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
5763
5764 * data/glr.c: Switch to Bison 2.2 special-exception language in
5765 the copyright notice. Use more-regular format for titles and
5766 copyright notices.

5776
5777 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
5778
5779 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
5780 that variable and the line breaks the bootstrap. Problem reported
5781 by Juan M. Guerrero.
5782
5783 2006-04-24 Akim Demaille <akim@lrde.epita.fr>

5803 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
5804
5805 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
5806 and didn't really work.
5807 For the index, use @ifnotinfo, not @iftex.
5808 Minor cleanups of spacing and terminology.

5814
5815 2006-03-12 Akim Demaille <akim@lrde.epita.fr>

5818 The test suite already exercize these cases.
5819 * data/c++.m4 (b4_namespace): New.
5820 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.
5821 * data/lalr1.cc (yytnameerr_): Move its definition into the namespace.
5822 * data/yacc.c, data/glr.c: Remove a useless `[]'.
5823 * doc/bison.texinfo: Document it.
5824 (Option Cross Key): Use @multitable in all formats. It looks
5825 nicer, even in TeX outputs.
5826 (Rules): Use the same code whatever the output type is.
5827 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
5828 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.
5829 * tests/calc.at: Use it, instead of hard coding `yy'.

5849
5850 Fix two nits reported by twlevo, plus one more that I discovered.
5851
5852 * src/assoc.h (assoc_to_string): Give a name to the arg, as
5853 this is the usual Bison style.
5854 * src/location.h (location_print): Likewise.
5855
5856 * src/reader.h (token_name): Likewise.
5857
5858 2006-03-08 Paul Eggert <eggert@cs.ucla.edu>
5859
5860 Fix some nits reported by twlevo.
5861 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
5862 and "POSIX". Use more-modern syntax for URLs. Mention C++
5863 and ask for Java. Don't hardwire OS version numbers. Add
5864 copyright notice.
5865 * m4/.cvsignore: Add unistd_h.m4, for latest gnulib.
5866 * src/conflicts.c (solved_conflicts_obstack): Now static.
5867
5868 2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
5869
5870 * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
5871 page. Say "you can use it" not "you may use it" as on the web page;
5872 we're describing capabilities not granting permission.
5873
5874 2006-03-06 Paul Eggert <eggert@cs.ucla.edu>
5875
5876 * data/glr.c (yyresolveLocations): Rename local variables to avoid
5877 shadowing warnings. Use usual patter for iterating through RHS.
5878 * tests/glr-regression.at
5879 (Uninitialized location when reporting ambiguity):
5880 Modify yylex so that it uses its argument, rather than trying
5881 to rely on ARGSUSED (which doesn't work for gcc with warnings).
5882 const char -> char const.
5883
5884 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
5885 Don't use tabs inside commands; it messes up 'ps'.
5886 Problem reported by twlevo.
5887
5888 2006-03-06 Joel E. Denny <jdenny@ces.clemson.edu>
5889
5890 * tests/glr-regression.at (Uninitialized location when reporting
5891 ambiguity): New test case.
5892 * data/glr.c (yyresolveLocations): New function, which uses
5893 YYLLOC_DEFAULT.
5894 (yyresolveValue): Invoke yyresolveLocations before reporting an
5895 ambiguity.
5896 * doc/bison.texinfo (Default Action for Locations): Note
5897 YYLLOC_DEFAULT's usage for ambiguity locations.
5898 (GLR Semantic Actions): Cross-reference those notes.
5899
5900 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
5901
5902 * tests/glr-regression.at (Leaked semantic values when reporting
5903 ambiguity): Remove unnecessary union and type declarations.
5904 (Leaked lookahead after nondeterministic parse syntax error): New test
5905 case.
5906 * data/glr.c (yyparse): Check for zero stacks remaining before
5907 attempting to shift the lookahead so that you don't lose it.
5908
5909 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5910
5911 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
5912 * tests/glr-regression.at (Leaked semantic values when reporting
5913 ambiguity): New test case.
5914 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
5915 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
5916 now unnecessary yystackp parameter.
5917 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
5918 destructors can be called.
5919
5920 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
5921 in existing testcases.
5922
5923 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
5924
5925 Don't leak semantic values for parent RHS when a user action cuts the
5926 parser, and clean up related code a bit.
5927 * tests/glr-regression.at (Leaked merged semantic value if user action
5928 cuts parse): Rename to...
5929 (Leaked semantic values if user action cuts parse): ... this. Add check
5930 for leaked parent RHS values.
5931 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
5932 between an unresolved state (non-empty chain of semantic options) and
5933 an incomplete one (signaled by an empty chain).
5934 (yyresolveStates): Document the interface. Move all manipulation of a
5935 successfully or unsuccessfully resolved yyGLRState to...
5936 (yyresolveValue): ... here so that yyresolveValue always leaves a
5937 yyGLRState with consistent data and thus is easier to understand.
5938 Remove the yyvalp and yylocp parameters since they are always just
5939 taken from the yys parameter. When reporting a discarded merged value
5940 in debugging output, note that it is incompletely merged. Document the
5941 interface.
5942 (yyresolveAction): If resolving any of the RHS states fails, destroy
5943 them all rather than leaking them. Thus, as long as user actions are
5944 written to clean up the RHS correctly, yyresolveAction always cleans up
5945 the RHS of a semantic option. Document the interface.

5947 2006-02-27 Paul Eggert <eggert@cs.ucla.edu>
5948

5952
5953 2006-02-21 Joel E. Denny <jdenny@ces.clemson.edu>

5963 __cplusplus && ! defined _STDLIB_H && !
5964 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||
5965 defined free))]: Include <stdlib.h> rather than rolling our own
5966 declarations of malloc and free, to avoid problems with
5967 incompatible declarations (using 'throw') C++'s stdlib.h. This
5968 should fix Debian bug 340012

5999 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
6000 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

6009 2.5.31. This resembles the 2005-10-10 patch to src/scan-skel.l.
6010
6011 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6012 nodist_PROGRAMS, since we don't need to actually compile the
6013 example if we're just doing a plain 'make'. This avoids bothering
6014 the installer unnecessarily about problems due to weird C++
6015 compilers.

6019 More portability fixes for problems summarized by Nelson H. F. Beebe.
6020
6021 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
6022 than #include "...", and compile with -I'.'. The old method was
6023 not portable, according to Posix and the C standard, and it does
6024 not work with Sun C 5.7, where previous #line directives affect
6025 the working directory used in later #include "..." directives.

6043 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6044 that '#include <string>' works.
6045
6046 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
6047 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
6048 "warning: sorry: semantics of inline function static data `const
6049 unsigned char translate_table[262]' are wrong (you'll wind up with
6050 multiple copies)".
6051
6052 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
6053 or, xor to not_, and_, or_, and xor_, respectively. This works
6054 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
6055 random system header somewhere that includes the equivalent of
6056 <iso646.h>.
6057
6058 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
6059 -E" works; it apparently doesn't work with PathScale EKO Compiler
6060 Suite Version 2.0.

6063
6064 During deterministic GLR operation, user actions should be able to
6065 influence the parse by changing yychar. To make this easier to fix and
6066 to make glr.c easier to evolve in general, don't maintain yytoken in
6067 parallel with yychar; just compute yytoken when needed.
6068 * tests/glr-regression.at (Incorrect lookahead during deterministic
6069 GLR): Check that setting yychar in a user action has the intended
6070 effect.
6071 * data/glr.c (yyGLRStack): Remove yytokenp member.
6072 (yyclearin): Don't set *yytokenp.
6073 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
6074 yychar rather than *yytokenp to determine the current lookahead.
6075 Compute yytoken locally when needed.
6076 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
6077 point to.
6078
6079 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
6080 after `--report' documentation.

6084 * src/parse-gram.y (grammar_declaration): Location of printer
6085 symbol is @1, not list->location. Bug reported by twlevo.
6086 * tests/input.at (Incompatible Aliases): Adjust to above change.
6087
6088 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
6089
6090 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
6091 all the test at once. This makes the output easier to read in the
6092 normal case.
6093
6094 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6095 got from <http://bro-ids.org/download.html>. The bug is that
6096 when two actions appeared in succession, the second one was
6097 scanned before the first one was added to the grammar rule
6098 as a midrule action. Bison then output the incorrect warning
6099 "parse.y:905.17-906.36: warning: unused value: $3".
6100 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6101 associated with a value.
6102 (rhs): Don't invoke grammar_current_rule_action_append.
6103 (action): Invoke it here instead.
6104 * src/reader.c (grammar_midrule_action): Now extern.
6105 (grammar_current_rule_action_append): Don't invoke
6106 grammar_midrule_action; that is now the scanner's job.
6107 * src/reader.h (last_string, last_braced_code_loc):
6108 (grammar_midrule_action): New decls.
6109 * src/scan-gram.l (last_string): Now extern, sigh.
6110 (last_braced_code_loc): New extern variable.
6111 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
6112 rule already has an action.
6113 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
6114 * tests/input.at (AT_CHECK_UNUSED_VALUES):
6115 Add some tests to check that the above changes fixed the bug.
6116
6117 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
6118
6119 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
6120 All used changed. Check whether the symbol has a destructor,
6121 not whether it is typed.
6122 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
6123 that the values are still reported as unused. All line numbers
6124 adjusted.
6125
6126 2006-01-23 Paul Eggert <eggert@cs.ucla.edu>

6128 Work around a bug in bro 0.8, which underparenthesizes its
6129 definition of YYLLOC_DEFAULT.

6131 their arguments.
6132 * data/lalr1.cc: Likewise.
6133 * data/yacc.cc: Likewise.
6134
6135 2006-01-22 Paul Eggert <eggert@cs.ucla.edu>
6136
6137 Work around a bug in Pike 7.0, and give the Pike folks a
6138 better way to override the usual int widths.
6139 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
6140 user can override the types.
6141 (short): #undef, to work around a bug in Pike 7.0.
6142 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
6143 (union yyalloc.yyss): Use yytype_int16 rather than short.
6144 All uses changed.
6145 (yysigned_char): Remove.
6146 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
6147 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
6148 * tests/regression.at (Web2c Actions): Adjust to above changes.
6149
6150 * src/reader.c (check_and_convert_grammar): New function.
6151 (reader): Close the input file even if something went wrong during
6152 parsing. Minor file descriptor leak reported by twlevo.
6153
6154 * src/assoc.c (assoc_to_string): Use a default: abort (); case
6155 to pacify gcc -Wswitch-default.
6156 * src/scan-gram.l (adjust_location): Use a default: break; case
6157 to pacify gcc -Wswitch-default.
6158 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
6159 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6160 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6161 Move these decls to scan-skel.l, since they don't need to be
6162 visible elsewhere.
6163 * src/scan-skel.l: Accept the above decls.
6164 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
6165 is used.
6166
6167 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
6168
6169 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
6170 since we don't want to insist on a version number at the start
6171 of the changelog every time.
6172 * Makefile.maint: Sync from coreutils a bit better.
6173 (sc_trailing_blank): Renamed from sc_trailing_space.
6174 All uses changed.
6175 (sc_no_if_have_config_h, sc_require_config_h):

6179 (sc_system_h_headers): Prefix with @.
6180 (sc_useless_cpp_parens, m4-check): Output line numbers.
6181 (changelog-check): Allow version only in head.
6182 * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
6183 satisfy new Makefile.maint rule.

6228 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
6229 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
6230 Put 'default: abort ();' before some other case, to satisfy older
6231 pedantic compilers.

6271 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
6272 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
6273 for the benefit of some pre-C99 compilers.
6274
6275 * bootstrap: Undo changes to gnulib files that autoreconf made.
6276
6277 Minor fixups to get 'make maintainer-check' to work.
6278 * configure.ac: Don't use -Wnested-externs, as it's incompatible
6279 with the new verify.h implementation.

6300
6301 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial

6322 (changelog-check): Don't require version number near head.
6323 (copyright-check): Use current year instead of hardwiring 2005.
6324 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
6325 (announcement): Add --gpg-key-ID.
6326
6327 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
6328 with "file system".
6329
6330 Avoid undefined behavior that addressed just before the start of an
6331 array. Problem reported by twlevo.
6332 * src/reader.c (packgram): Prepend a new sentinel before ritem.
6333 * src/lalr.c (build_relations): Rely on new sentinel.

6344
6345 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6346
6347 * data/glr.c (yysplitStack): A little stylistic rewrite.
6348

6352
6353 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
6354
6355 * doc/bison.texinfo: Fix some typos.
6356 (GLR Semantic Actions): New subsection discussing special
6357 considerations because GLR semantic actions might be deferred.
6358 (Actions): Mention look-ahead usage of yylval.
6359 (Actions and Locations): Mention look-ahead usage of yylloc.
6360 (Special Features for Use in Actions): Add YYEOF entry and mention it
6361 in the yychar entry.
6362 In the yychar entry, remove mention of the local yychar case (pure
6363 parser) since this is irrelevant information when writing semantic
6364 actions and since it's already discussed in `Table of Symbols' where
6365 yychar is otherwise described as an external variable.
6366 In the yychar entry, don't call it the `current' look-ahead since it
6367 isn't when semantic actions are deferred.
6368 In the yychar and yyclearin entries, add note about deferred semantic
6369 actions.
6370 Add yylloc and yylval entries discussing look-ahead usage.
6371 (Look-Ahead Tokens): When discussing yychar, don't call it the
6372 `current' look-ahead, and do mention yylval and yylloc.
6373 (Error Recovery): Cross-reference `Action Features' when mentioning
6374 yyclearin.
6375 (Table of Symbols): In the yychar entry, don't call it the `current'
6376 look-ahead.
6377 In the yylloc and yylval entries, mention look-ahead usage.
6378
6379 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6380

6382
6383 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6384
6385 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
6386 use during nondeterministic operation to track which stacks have
6387 actually needed the current lookahead.
6388 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
6389 Allocate, deallocate, resize, and otherwise shuffle space for
6390 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
6391 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6392 appropriately during nondeterministic operation.
6393 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6394 members to store the current lookahead to be used by the deferred
6395 user action.
6396 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6397 from which the RHS is taken. Set the lookahead members of the new
6398 yySemanticOption according to the lookahead status for stack yyk.
6399 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
6400 yyaddDeferredAction.
6401 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
6402 members of yySemanticOption before invoking yyuserAction, and then set
6403 them back to their current values afterward.
6404 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
6405 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
6406 * tests/glr-regression.at: Remove `.' from the ends of recent test case
6407 titles for consistency.
6408 (Leaked merged semantic value if user action cuts parse): In order to
6409 suppress lint warnings, use arguments in merge function, and assign
6410 char value < 128 in main.
6411 (Incorrect lookahead during deterministic GLR): New test case.
6412 (Incorrect lookahead during nondeterministic GLR): New test case.
6413
6414 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6415
6416 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
6417 !yyvaluep as signal that no semantic value is available to print.
6418 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
6419 to print a semantic value.
6420
6421 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6422
6423 * tests/glr-regression.at: For consistency with my newer test cases,
6424 don't thank myself.
6425
6426 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6427
6428 * data/glr.c (yyresolveValue): When merging semantic options, if at
6429 least one user action succeeds but a later one cuts the parse, then
6430 destroy the semantic value before returning rather than leaking it.
6431 (yyresolveStates): If a user action cuts the parse and thus
6432 yyresolveValue fails, ignore the (unset) semantic value rather than
6433 corrupting the yyGLRState, and empty the semantic options list since
6434 the user actions should have called all necessary destructors.
6435 Simplify code with YYCHK.
6436 * tests/glr-regression.at (Corrupted semantic options if user action
6437 cuts parse): New test case.
6438 (Undesirable destructors if user action cuts parse): New test case.
6439 Before applying any of this patch, this test case never actually failed
6440 for me... but only because the corrupted semantic options usually
6441 masked this bug.
6442 (Leaked merged semantic value if user action cuts parse): New test
6443 case.
6444
6445 2006-01-05 Akim Demaille <akim@epita.fr>

6455 b4_c_modern.
6456 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather

6472
6473 2006-01-04 Akim Demaille <akim@epita.fr>
6474
6475 * src/reader.c (grammar_midrule_action): If $$ is set in a
6476 mid-rule, move the `used' bit to its lhs.
6477 * tests/input.at (Unused values): New.
6478 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
6479
6480 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
6481
6482 * doc/bison.texinfo (Bison Options): Say more accurately what
6483 --yacc does.
6484 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
6485 about declarations in the grammar when in Yacc mode, as POSIX does
6486 not require a diagnostic when the grammar uses extensions.
6487
6488 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
6489
6490 Warn about dubious constructions like "%token T T".
6491 Reported by twlevo.

6493 * src/symtab.c (symbol_new): Initialize it to false.
6494 (symbol_class_set): New arg DECLARING, specifying whether
6495 this is a declaration that we want to warn about, if there
6496 is more than one of them. All uses changed.
6497
6498 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
6499 Allow multiple %union directives, whose contents concatenate.
6500 * src/parse-gram.y (grammar_declaration): Likewise.
6501 Use muscle_code_grow, so that we don't need stype_line any more.
6502 All uses changed.
6503
6504 * src/muscle_tab.c (muscle_grow): Fix comment.
6505
6506 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
6507 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
6508 Update copyright year to 2006.
6509
6510 2006-01-03 Akim Demaille <akim@epita.fr>
6511
6512 Have glr.cc pass (some of) the calc.at tests.
6513 * data/glr.cc (b4_parse_param_orig): New.
6514 (b4_parse_param): Improve its definition, and bound it more
6515 clearly in the skeleton.
6516 (b4_epilogue): Append, instead of prepending, in order to keep
6517 #line consistency.
6518 Simplify the generation of auxiliary functions: locations and

6529 (AT_CHECK_CALC_GLR_CC): New.
6530 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
6531
6532 2006-01-02 Akim Demaille <akim@epita.fr>
6533
6534 * src/output.c (output_skeleton): Don't hard wire the inclusion of
6535 c.m4.

6580
6581 2005-12-27 Akim Demaille <akim@epita.fr>
6582
6583 * src/reader.c (grammar_current_rule_check): Also check that $$
6584 is used.
6585 Take the rule to check as argument, hence rename as...
6586 (grammar_rule_check): this.
6587 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
6588 Rename as...
6589 (grammar_rule_begin, grammar_rule_end): these, for consistency.
6590 (grammar_midrule_action, grammar_symbol_append): Now static.
6591 * tests/torture.at (input): Don't rely on the default action
6592 being always performed.

6655 * tests/cxx-type.at: Cast results of malloc, for C++.
6656
6657 2005-12-21 Joel E. Denny <address@hidden>
6658
6659 * tests/cxx-type.at: Construct a tree, count the parents of shared
6660 nodes, and free each node once and only once. Previously, the memory
6661 for semantic values was leaked instead.
6662
6663 2005-12-21 Joel E. Denny <address@hidden>
6664
6665 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
6666 (yylval, yylloc): If pure, #define to yystackp->yyval and
6667 yystackp->yyloc similar to yychar and yynerrs.
6668 (yyparse): If pure, remove local yylval and yylloc. Add local
6669 yystackp to accommodate pure definitions of yylval and yylloc.
6670 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
6671 yylvalp and yyllocp to &yylval and &yylloc.
6672 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
6673 namespace. Previously, nerrs and char were missing, but lval and lloc
6674 weren't necessary.
6675 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
6676 yylvalp and yyllocp parameters since, if pure, these are now always
6677 accessible through yystackp. If not pure, they are still accessible
6678 globally.
6679 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
6680 `if (YYID (N))' to pacify lint.
6681
6682 2005-12-21 Akim Demaille <akim@epita.fr>
6683
6684 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
6685 destroy the RHS symbols of a rule.
6686 * data/yacc.c (yylen): Initialize to 0.
6687 Keep its value to the number of items to possibly shift.
6688 In particular, a regular successful parse that ends on YYFINAL by
6689 a (internal) YYACCEPT must not have yylen != 0.
6690 (yyerrorlab, yyreturn): Pop the RHS.
6691 Reorder a bit to emphasize the `shifting' bits of code.
6692 (YYPOPSTACK): Now accept a number of items to pop.
6693 * data/lalr1.cc: Likewise.
6694 * data/glr.c: Formatting changes.
6695 Use goto instead of fall through.
6696 * doc/bison.texinfo (Destructor Decl): Complete.
6697

6701 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
6702 * djgpp/config.bat: Replace every occurence of the file name
6703 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
6704 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6705 * djgpp/config.sed: Replace every occurence of the file name
6706 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
6707 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
6708 * djgpp/djunpack.bat: DJGPP specific file.
6709 * djgpp/fnchange.lst: DJGPP specific file.
6710 * djgpp/README.in: Add new information about how to unpack the bison
6711 source on MSDOS and other systems which have 8.3 file name restrictions
6712 using djunpack.bat and fnchange.lst.
6713
6714 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
6715
6716 * bootstrap (build_cvs_prefix): Remove; unused.
6717 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
6718 when getting gnulib.
6719
6720 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
6721
6722 * data/glr.c: Reorder typedef declarations for structs to match order
6723 of struct declarations.
6724 Rename yystack everywhere to yystackp except in yyparse where it's not
6725 a pointer.
6726 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
6727 consistency.
6728 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
6729 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.
6730 (yyparse): Change while (yytrue) to while ( YYID (yytrue)) to pacify
6731 lint.
6732
6733 2005-12-09 Paul Eggert <eggert@cs.ucla.edu>
6734
6735 * tests/sets.at (Accept): Fix typos in regular expression used to
6736 sed out the final state number.
6737
6738 Work around portability problem on Solaris 10: flex-generated
6739 files include <stdio.h> before <config.h>, which messes up
6740 because the latter defines __EXTENSIONS__. Address the problem
6741 by creating two new little files that include <config.h> first,
6742 then include the flex-generated files. Rewrite everyone else
6743 to include <config.h> first, as well.
6744 * lib/timevar.c: Always include "config.h".
6745 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

6779 (current_lhs, current_lhs_location): Now static.
6780 (current_assoc): Remove unused variable.
6781
6782 Cleanups so that Bison-generated parsers have less lint.
6783 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
6784 Prepend /*ARGSUSED*/, for lint's sake.
6785 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
6786 definition if 'lint' is defined.
6787 (YYID): New macro (or function, if lint).
6788 All uses of /*CONSTCOND*/0 replaced by YYID(0).
6789 * data/yacc.c: Likewise.
6790 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
6791 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
6792 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
6793 is C++ only.
6794 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
6795 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
6796 Use YYID(0) rather than 0, for lint.
6797 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
6798 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
6799

6809 all stacks.
6810 (yyparse): Iterate another stack in order to call user destructors.
6811 * tests/glr-regression.at (No users destructors if stack 0 deleted):
6812 New test case.
6813 (Duplicated user destructor for lookahead): This test now is expected
6814 to succeed.
6815
6816 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
6817
6818 * NEWS: Document the following change.
6819 * data/yacc.c: Say "parser skeleton" rather than "file", since
6820 it's no longer just a file.
6821 * data/glr.c: Grant a special exception for C GLR parsers, that
6822 reads like the already-existing exception for C LALR(1) parsers.
6823 * data/glr.cc: Likewise.
6824 * data/lalr1.cc: Likewise.
6825 * data/location.cc: Likewise.
6826 * data/yacc.c: Reword the "written by" statement to clarify that
6827 it was the parser skeleton, not the entire output file.
6828 * data/glr.c: Written by Paul Hilfinger.
6829 * data/glr.cc: Written by Akim Demaille.
6830 * data/lalr1.cc: Likewise.
6831

6833
6834 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
6835 Fix typos in previous change that broke 'make check'.
6836 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
6837 supported in C.
6838 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
6839 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
6840 We can revert this once things settle down.
6841
6842 * src/conflicts.c (conflicts_print): Don't print file name twice
6843 when %expect fails because there were no conflicts.
6844 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
6845 change.
6846 * tests/conflicts.at (%expect not enough, %expect too much):
6847 (%expect with reduce conflicts): Adjust to new behavior.

6870
6871 2005-11-14 Akim Demaille <akim@epita.fr>
6872
6873 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
6874 from 1 to N, while values and location start at 0.
6875 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
6876

6979
6980 * bootstrap (cleanup_gnulib): New function. Use it to clean up
6981 gnulib when interrupted. This fixes some race conditions and
6982 works around some portability problems (one noted by Paul
6983 Hilfinger).
6984

7027 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
7028
7029 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
7030 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
7031 Problem reported by John P. Hartmann.
7032 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
7033 already defined it.
7034

7083 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7084
7085 Undo the parts of the unlocked-I/O change that substituted
7086 putc or puts for printf. This might hurt performance a bit,
7087 but some people prefer the printf style.
7088 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
7089 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
7090 All uses replaced by YYFPRINTF and YYDPRINTF.
7091 * data/yacc.c: Likewise.
7092 * lib/bitset.c (bitset_print): Likewise.
7093 * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer printf to
7094 putc and puts.
7095 * lib/lbitset.c (debug_lbitset): Likewise.
7096 * src/closure.c (print_firsts, print_fderives): Likewise.
7097 * src/gram.c (grammar_dump): Likewise.

7099 * src/output.c (escaped_output): Likewise.
7100 (user_actions_output): Break apart two printfs.

7104 * src/system.h: Include unlocked-io.h rathe than stdio.h.
7105
7106 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
7107 Use assignments rather than casts-to-void to suppress
7108 unused-variable warnings. This pacifies 'lint'.
7109 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
7110 unused-variable warnings.
7111
7112 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>

7115
7116 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
7117
7118 Use unlocked I/O for a minor performance improvement on hosts like
7119 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7120 is to use the gnlib unlocked-io module, and to prefer putc and
7121 puts to printf when either will work (since the latter doesn't
7122 come in an unlocked flavor).
7123 * bootstrap (gnulib_modules): Add unlocked-io.
7124 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
7125 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.

7135 * src/gram.c (grammar_dump): Likewise.
7136 * src/lalr.c (look_ahead_tokens_print): Likewise.
7137 * src/output.c (escaped_output): Likewise.
7138 (user_actions_output): Coalesce two printfs.
7139 * src/parse-gram.y (%printer): Prefer putc and puts to printf.
7140 * src/reduce.c (reduce_print): Likewise.
7141 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
7142 * src/system.h: Include unlocked-io.h rather than stdio.h.
7143
7144 * data/lalr1.cc: Don't put an unmatched ' in a dnl comment, as
7145 this confuses xgettext.

7188
7189 * lib/subpipe.c: New function end_of_output_subpipe() added
7190 to allow support for non-posix systems. This is a no-op function
7191 for posix systems.
7192
7193 * lib/subpipe.h: New function end_of_output_subpipe() added
7194 to allow support for non-posix systems. This is a no-op function
7195 for posix systems.
7196
7197 * src/output.c (output_skeleton): Use end_of_output_subpipe() to
7198 handle the lack of pipe/fork functionality on non-posix systems.

7219 * data/lalr1.cc: here.
7220 (location.hh): Include it after the user prologue, in case the
7221 filename type is defined by the user.
7222 Forward declation location and position before the pre-prologue.
7223 (yyresult_): Rename as...
7224 (yyresult): this, it's a local variable, not an attribute.
7225 * data/Makefile.am (dist_pkgdata_DATA): Adjust.
7226
7227 2005-10-01 Akim Demaille <akim@epita.fr>

7263 parser members, replaced by...
7264 (yyn, yylen, yystate, yynerss, yyerrstatus): these parser::parse
7265 local variables.
7266 (yysyntax_error_): Takes the state number as argument.
7267 (yyreduce_print_): Use the argument yyrule, not the former
7268 attribute yyn_.

7270 2005-09-26 Paul Eggert <eggert@cs.ucla.edu>
7271
7272 * bootstrap (gnulib_modules): Add verify.

7283 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
7284 Trivial changes from Joel E. Denny.
7285
7286 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7287 it itself.
7288 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7289 don't use alloca any more.
7290
7291 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7292 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7293 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7294 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7295 to match yacc.c, to test more hosts.
7296
7297 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7298
7299 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7300 doesn't affect behavior.
7301 (YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
7302 Solaris, AIX, MSC.
7303 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7304 This works a bit better with glibc, if user code has already included
7305 stdlib.h.
7306 * doc/bison.texinfo (Bison Parser): Document that users can't
7307 arbitrarily use malloc and free for other purposes. Document
7308 that <alloca.h> and <malloc.h> might be included.
7309 (Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
7310 user must declare alloca.

7321 * data/yacc.c (YYSIZE_MAXIMUM): New macro.
7322 (YYSTACK_ALLOC_MAXIMUM): Use it.
7323 (yysyntax_error): New function.
7324 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7325 multiple syntax errors are reported, and alloca is being used.
7326 Instead, reallocate buffers twice as big each time, so that
7327 we waste at most half the allocated memory. Start with a small
7328 (128-byte) buffer that will suffice in most cases anyway.
7329 Use yysyntax_error to do most of the work.
7330
7331 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7332 yynerrs is the number of errors reported, not the number of
7333 errors encountered.
7334
7335 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7336 Mark it as expected to fail.
7337 Cast result of malloc; problem reported by twlevo@xs4all.nl.
7338 * tests/actions.at, tests/calc.at, tests/glr-regression.at:
7339 Don't start user-code symbols with "yy", to avoid name space problems.
7340
7341 2005-09-19 Akim Demaille <akim@epita.fr>
7342
7343 Remove the traits, failed experiment.
7344 It never proved useful, and anyway because of the current
7345 definition, it was not possible to have several specialization of
7346 this traits, making it useless.
7347 * data/lalr1.cc (yy:traits): Remove.
7348 Inline its definitions in the parser class.
7349
7350 2005-09-19 Akim Demaille <akim@epita.fr>

7372 * src/output.c (prepare): Likewise.
7373 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7374 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7375 is not defined. This is an awful hack, but it's enough for now.
7376 All callers changed.
7377 * tests/glr-regression-at (make_value): Args are const pointers now,
7378 to avoid GCC warning.
7379 (Duplicated user destructor for lookahead): New test. Currently
7380 skipped. It fails on my host but I'm not sure it'll always fail.
7381
7382 2005-09-16 Akim Demaille <akim@epita.fr>
7383
7384 * src/symtab.h (struct symbol): Declare the printer and destructor

7403 (yyreport_syntax_error_): Remove, replaced by...
7404 (yysyntax_error_): this which returns a string and leaves to the
7405 caller the call to the users' error function.
7406 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7407 Move from members of the parser object...
7408 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

7410
7411 2005-09-16 Akim Demaille <akim@epita.fr>
7412
7413 * doc/bison.texinfo (Calc++ Parser): Don't promote defining YYEOF

7417
7418 * data/glr.c (yyresolveValue): Add default case to pacify

7433 do anything if $@ exists. This reverts part of the 2005-07-07
7434 patch.
7435
7436 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7437
7438 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7439 contains obsolete information and isn't worth distributing as a
7440 separate file anyway.
7441 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
7442 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

7454 Problem reported by twlevo@xs4all.nl.
7455
7456 * doc/bison.texinfo: Don't use "filename", as per GNU coding
7457 standards. Use "file name" or "file" or "name", depending on
7458 the context.
7459 (Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
7460 not to hack/foo.tab.c.

7480 Add casts to pacify g++. Problem reported by twlevo@xs4all.nl.
7481
7482 * bootstrap: Add comment as to why the AM_LANGINFO_CODESET hack is
7483 needed.
7484

7486
7487 * data/glr.c (yydestroyGLRState): Renamed from yydestroyStackItem.

7509
7510 2005-08-25 Akim Demaille <akim@epita.fr>
7511
7512 * tests/local.at (AT_COMPILE_CXX): Pass $LINKS too.
7513
7514 2005-08-24 Paul Eggert <eggert@cs.ucla.edu>
7515
7516 * data/glr.c (yyrecoverSyntaxError, yyreturn):
7517 Don't invoke destructor on unresolved entries.
7518 * tests/glr-regression.at
7519 (User destructor for unresolved GLR semantic value): New test case.
7520 Problem reported by Joel E. Denny in:
7521 http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00016.html
7522
7523 2005-08-21 Paul Eggert <eggert@cs.ucla.edu>
7524
7525 * lib/.cvsignore: Remove realloc.c, strncasecmp.c, xstrdup.c.
7526 Add strnlen.c.
7527 * m4/.cvsignore: Remove codeset.m4, gettext.m4, lib-ld.m4,
7528 lib-prefix.m4, po.m4.
7529
7530 * data/glr.c (yyreturn): Use "Cleanup:" rather than "Error:"
7531 in yydestruct diagnostic, since it might not be an error.
7532 Problem reported by Joel Denny near end of
7533 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7534 * data/lalr1.cc (yyerturn): Likewise.
7535 * data/yacc.c (yyreturn): Likewise.
7536 * tests/calc.at (_AT_CHECK_CALC_ERROR): Adjust to the above change.
7537
7538 * src/files.c: Remove obsolete FIXME comment.
7539
7540 * data/glr.c (YY_SYMBOL_PRINT): Append a newline, for consistency
7541 with the other templates, and to fix bogus run-on messages such
7542 as the one reported at the end of
7543 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
7544 All callers changed to avoid the newline.
7545 (yyprocessOneStack): Output two lines rather than one, to accommodate
7546 the above change. This changes the debug output format slightly.
7547
7548 * data/glr.c (yyresolveValue): Fix redundant parse tree problem
7549 reported by Joel E. Denny in
7550 <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>
7551 (trivial change).
7552 * tests/glr-regression.at (Duplicate representation of merged trees):
7553 New test, from Joel E. Denny in:
7554 <http://lists.gnu.org/archive/html/help-bison/2005-07/msg00013.html>.
7555 * THANKS: Add Joel E. Denny.
7556
7557 * configure.ac (AC_INIT): Bump to 2.0c.
7558
7559 2005-07-24 Paul Eggert <eggert@cs.ucla.edu>
7560
7561 * NEWS: Version 2.0b.
7562
7563 * Makefile.am (SUBDIRS): Put examples before tests, so that
7564 "make check" doesn't finish with "All 1 tests passed".
7565
7566 * tests/regression.at (Token definitions): Don't rely on
7567 AT_PARSER_CHECK for data that contains backslashes. It currently
7568 uses 'echo', and 'echo' isn't portable if its argument contains
7569 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7570 that the byte '\0xff' is not printable in the C locale; it is,
7571 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7572 not printable, so use '\0x81' to test.
7573
7574 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7575 version of GCC, since the macro is used with non-GCC compilers.
7576
7577 Fix core dump reported by Pablo De Napoli in
7578 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7579 * tests/regression.at (Invalid inputs with {}): New test.
7580 * src/parse-gram.y (token_name): Translate type before using
7581 it as an index.
7582
7583 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7584 the user's name space. All uses changed to __attribute__
7585 ((__unused__)).
7586 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7587 Add __attribute__ ((__noreturn__)).
7588
7589 * etc/clcommit: Remove. We weren't using it, and it failed
7590 "make maintainer-distcheck".
7591 * Makefile.maint: Merge from coreutils.
7592 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7593 (syntax-check-rules): Change list of rules as described below.
7594 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
7595 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
7596 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):
7597 (sc_trailing_space): New rules.
7598 (sc_xalloc_h_in_src): Remove.
7599 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
7600 (sc_space_tab, sc_error_exit_success, sc_changelog):
7601 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
7602 (makefile-check, po-check, author_mark_check):
7603 (makefile_path_separator_check, copyright-check):
7604 Use grep -n, to make it easier to find violations.
7605 Use CVS_LIST and CVS_LIST_EXCEPT.
7606 (header_regexp, h_re): Remove.
7607 (dd_c): New macro.
7608 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7609 (my-distcheck): Use more-modern GCC flags.
7610 (signatures, %.asc): Remove.
7611 (rel-files, announcement): Remove signatures.
7612 Restore old updating code, even though we don't use it, so
7613 that we're the same as coreutils.
7614 (alpha, beta, major): Depend on news-date-check.
7615 Make the upload commands.
7616
7617 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
7618 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
7619 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
7620 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.
7621 * src/Makefile.am, src/gram.c, src/muscle_tab.h: Likewise.
7622 * src/parse-gram.y, src/system.h, src/tables.c, src/vcg.c: Likewise.
7623 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
7624 * tests/sets.at: Likewise.
7625
7626 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7627 we comment out the Autoconf version number.
7628 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7629 it's error-prone and "make maintainer-distcheck" rejects it.
7630
7631 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7632 Indent calls to "error" to pacify "make maintainer-distcheck",
7633 when the calls are not intended to be translated.
7634 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
7635
7636 * src/Makefile.am (DEFS): Use +=, to pacify
7637 "make maintainer-distcheck".
7638 (bison_SOURCES): Add scan-skel.h.
7639 (sc_tight_scope): New rule, from coreutils.
7640
7641 * src/files.c (src_extension, header_extension):
7642 Now static, not extern.
7643 * src/getargs.c (short_options): Likewise.
7644 * src/muscle_tab.c (muscle_table): Likewise.
7645 * src/parse-gram.y (current_class, current_type, current_prec):
7646 Likewise.
7647 * src/reader.c (grammar_end, previous_rule_end): Likewise.
7648 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
7649 * src/main.c (main): Cast bindtextdomain and textdomain calls to
7650 void, to avoid warning when NLS is disabled.
7651 * src/output.c: Include scan-skel.h.
7652 (scan_skel): Remove decl, since scan-skel.h does this.
7653 (output_skeleton):
7654 Indent calls to "error" to pacify "make maintainer-distcheck".
7655 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
7656 * src/reader.h (gram_end, gram_lineno): New decls to pacify
7657 "make maintainer-distcheck".
7658 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
7659 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
7660 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
7661 (skel_lex_destroy, scan_skel): Move these decls to...
7662 * src/scan-skel.h: New file.
7663 * src/uniqstr.c (uniqstr_assert):
7664 Indent calls to "error" to pacify "make maintainer-distcheck".
7665
7666 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
7667 not @VAR@.
7668
7669 * tests/torture.at: Revamp to avoid misuse of atoi that
7670 "make maintainer-distcheck" complained about.
7671
7672 * examples/extexi (message): Don't print a message more than once,
7673 and omit line-number decoration that makes Emacs compile think
7674 that informative messages are worth worrying about.
7675
7676 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
7677
7678 * configure.ac: Update version number.
7679
7680 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
7681 accidentally.
7682 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
7683 autogenerated by the maintainer.
7684 * examples/calc++/.cvsignore: Add *.yy.
7685
7686 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
7687 * lib/bitset_stats.c (bitset_stats_init): Likewise.
7688 * lib/bitsetv.c (bitsetv_alloc): Likewise.
7689
7690 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
7691
7692 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
7693 from maintainer-distcheck about casting the argument of 'free'.
7694
7695 * NEWS: Mention recent yytname changes.
7696 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
7697
7698 * bootstrap: For translations that have not yet been upgraded to
7699 the new runtime-po domain, prime the pump by extracting the
7700 relevant strings from the obsolete translations. This code can be
7701 removed once the bison-runtime domain has been translated by each
7702 team.
7703
7704 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
7705 now that token names are already quoted.
7706
7707 Fix problem reported by Anthony Heading.
7708 * data/glr.c (YYTOKEN_TABLE): New macro.
7709 (yytname): Define if YYTOKEN_TABLE.
7710 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
7711 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
7712 (YYERROR_VERBOSE): Define the same way the other skeletons do.
7713 * src/output.c (prepare_symbols): Output token_table_flag.
7714
7715 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
7716
7717 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
7718 again if the first call fails.
7719
7720 * data/glr.c (yytnamerr): New function.
7721 (yyreportSyntaxError): Use it to dequote most string literals.
7722 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
7723 with other skeletons. All uses changed.
7724 (yytnameerr_): New function.
7725 (yyreport_syntax_error): Use it to dequote most string literals.
7726 * data/yacc.c (yytnamerr): New function.
7727 (yyerrlab): Use it to decode most string literals.
7728 * doc/bison.texinfo (Decl Summary, Calling Convention):
7729 Clarify quoting convention of yytname.
7730 * src/output.c (prepare_symbols): Quote all names. This undoes
7731 the 2005-04-17 change, which is now accomplished (mostly) via
7732 changes in the parsers as described above.
7733 * tests/regression.at (Token definitions, Web2c Actions):
7734 Undo most 2005-04-17 change here, too.
7735
7736 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
7737
7738 Fix more problems reported by twlevo@xs4all.nl.
7739 * tests/cxx-type.at: Don't pipe output of ./types through sed to
7740 remove trailing spaces. This loses the exit status of ./types,
7741 and isn't needed since ./types shouldn't be emitting trailing
7742 spaces.
7743 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
7744 as the stack isn't valid in that case.
7745
7746 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
7747 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
7748 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
7749 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
7750 is used.
7751 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
7752 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
7753 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
7754 Likewise.
7755
7756 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
7757 overly-picky compilers that reject 'char *foo = "bar";'.
7758
7759 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
7760 to FILE * parameter, not to stderr. This fixes a typo introduced
7761 in the 2005-07-12 change.
7762
7763 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
7764 warnings from GCC 4.
7765
7766 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
7767 (yyglrShiftDefer, yysplitStack):
7768 Remove unused parameters b4_pure_formals. All uses changed.
7769 (yyglrShift): Remove unused parameters b4_user_formals.
7770 All uses changed.
7771 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
7772
7773 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
7774
7775 Destructor cleanups and regularization among the three skeletons.
7776 * NEWS: Document the behavior changes.
7777 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
7778 stack before failing, as the cleanup code will do it for us now.
7779 * data/lalr1.cc (yyerrlab): Likewise.
7780 * data/glr.c (yyparse): Pop everything off the stack before
7781 freeing it, so that destructors get called properly.
7782 * data/lalr1.cc (yyreturn): Likewise.
7783 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
7784 This is more consistent.
7785 * doc/bison.texinfo (Destructor Decl): Mention more reasons
7786 why destructors might be called. 1.875 -> 2.1.
7787 (Destructor Decl, Decl Summary, Table of Symbols):
7788 Some English-language cleanups for %destructor.
7789 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
7790 Add output line for destructor of start symbol.
7791 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
7792 because of that same extra output line.
7793
7794 * NEWS: Document minor wording changes in diagnostics of
7795 Bison-generated parsers.
7796 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
7797 Remove unused formals. All uses changed.
7798 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
7799 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
7800 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
7801 Rename yyoverflowab to yyexhaustedlab.
7802 When memory exhaustion occurs during syntax-error reporting,
7803 report it separately rather than in a single diagnostic; this
7804 eases translation.
7805 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
7806 (Memory Exhausted): Renamed from Parser Stack Overflow.
7807 Revamp wording slightly to prefer "memory exhaustion".
7808 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
7809
7810 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
7811
7812 Add i18n support to the GLR skeleton. Partially fix the C++
7813 skeleton; a C++ expert needs to finish this. Remove debugging
7814 msgids; there's little point to having them translated, since they
7815 can be understood only by someone who can read the
7816 (English-language) source code.
7817
7818 Generate runtime-po/bison-runtime.pot automatically, so that we
7819 don't have to worry about garbage getting in that file. We'll
7820 make sure after the next official release that old msgids don't
7821 get lost. See
7822 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
7823
7824 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
7825 Now auto-generated.
7826 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
7827 Fix typos in explanations of the runtime file.
7828 * bootstrap: Change gettext keyword from YYI18N to YY_.
7829 Use standard Makefile.in.in in runtime-po, since we'll arrange
7830 for backward-compatible bison-runtime.po files in a different way.
7831 * data/glr.c (YY_): New macro, from yacc.c.
7832 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
7833 Translate messages intended for users.
7834 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
7835 the wording in the other skeletons. We don't know that the memory
7836 is virtual.
7837 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
7838 Use same method that yacc.c uses.
7839 Don't translate debugging messages.
7840 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
7841 it doesn't work (yet), and requires C++ expertise to fix.
7842 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
7843 Move defn to a more logical place, to be consistent with other
7844 skeletons.
7845 Don't translate debugging messages.
7846 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
7847 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
7848 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
7849 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
7850
7851 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
7852 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
7853 void, not int.
7854 * tests/glr-regression.at (Badly Collapsed GLR States):
7855 Likewise.
7856 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7857 yylex should return 0 at EOF rather than aborting.
7858
7859 Improve tests for stack overflow in GLR parser.
7860 Problem reported by twlevo@xs4all.nl.
7861 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
7862 All uses removed.
7863 (yyStackOverflow): Just longjmp, but with value 2 so that caller
7864 can handle the problem.
7865 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
7866 (yyparse): New local variable yyresult to record the result.
7867 Use result of setjmp to set it, rather than storing itinto
7868 struct.
7869 (yyDone): Remove label.
7870 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
7871 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
7872 if YYABORT is used).
7873 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
7874 yyparse status; put status > 1 into diagnostic.
7875 Check that status==2 works.
7876 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
7877 Use exit status 3 for failure to open (which shouldn't happen).
7878
7879 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
7880
7881 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
7882 1 on syntax error; just let yyparse do its thing.
7883 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
7884 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
7885 (Exploding the Stack Size with Alloca):
7886 (Exploding the Stack Size with Malloc):
7887 Expect exit status 2, not 1, since the parser is supposed to blow
7888 its stack. Problem reported by twlevo@xs4all.nl.
7889
7890 * data/glr.c (yyparse): Don't assume that the initial calls
7891 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
7892 Print a stack-overflow message and fail instead.
7893 Initialize the line-number information before creating the stack,
7894 so that the stack-overflow message can report line zero safely.
7895
7896 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
7897
7898 Fix problems reported by twlevo@xs4all.nl.
7899 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
7900 (yyuserMerge): Provide a default case if b4_mergers is empty.
7901 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
7902 * tests/glr-regression.at
7903 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
7904 Add casts to pacify C++ compilers.
7905 * tests/glr-regression.at (Improper merging of GLR delayed action
7906 sets): Declare yylex before using it.
7907 * tests/Makefile.am (maintainer-check-g++): Fix a stray
7908 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
7909 test for valgrind; valgrind is independent of g++.
7910 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
7911 for compatibility with POSIX 1003.1-2001 (if running coreutils).
7912 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
7913 Use a destructor, so that we can expand the stack. Change
7914 YYSTYPE to char * so that we can free it. Cast result of malloc.
7915
7916 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
7917
7918 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
7919 a valgrind failure. Problem reported by twlevo@xs4all.nl.
7920
7921 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
7922
7923 * PACKAGING: New file, suggested by Bruno Haible and taken from
7924 similar wording in gettext's PACKAGING file.
7925 * NEWS: Mention PACKAGING.
7926 * Makefile.am (EXTRA_DIST): Add PACKAGING.
7927
7928 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
7929
7930 * NEWS: Document recent i18n improvements.
7931 * bootstrap: Get runtime translations into runtime-po.
7932 Create runtime-po files automatically, if possible.
7933 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
7934 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
7935 does not infringe on the user's name space.
7936 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
7937 * doc/bison.texinfo (Internationalization): Revamp the English
7938 and Texinfo syntax a bit, to try to make it clearer.
7939 (Bison Options, Option Cross Key): Mention --print-localedir.
7940 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
7941 YYENABLE_NLS. Quote a bit more.
7942 * runtime-po/.cvsignore: New file.
7943 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
7944 * runtime-po/Rules-quot: Remove; now created by bootstrap.
7945 * runtime-po/quot.sed: Likewise.
7946 * runtime-po/boldquot.sed: Likewise.

7951 * runtime-po/Makevars: Likewise.
7952 * runtime-po/LINGUAS: Likewise.
7953 * runtime-po/de.po: Likewise; we will rely on the translation project
7954 to maintain this, so "bootstrap" should get it.
7955 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
7956 its value.
7957 * src/main.c (main): Bind the bison-runtime domain, too.
7958
7959 2005-07-12 Bruno Haible <bruno@clisp.org>
7960
7961 * data/yacc.c: Include <libintl.h> when NLS is enabled.
7962 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
7963 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
7964 * runtime-po: New directory.
7965 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
7966 $(DOMAIN).pot-update rule, so that old messages are never dropped.
7967 * runtime-po/Rules-quot: New file, copied from po/.
7968 * runtime-po/quot.sed: Likewise.
7969 * runtime-po/boldquot.sed: Likewise.
7970 * runtime-po/en@quot.header: Likewise.
7971 * runtime-po/en@boldquot.header: Likewise.
7972 * runtime-po/insert-header.sin: Likewise.
7973 * runtime-po/remove-potcdate.sin: Likewise.
7974 * runtime-po/Makevars: New file.
7975 * runtime-po/POTFILES.in: New file.
7976 * runtime-po/LINGUAS: New file.
7977 * runtime-po/bison-runtime.pot: New file.
7978 * runtime-po/de.po: New file.
7979 * m4/bison.m4: New file.
7980 * Makefile.am (SUBDIRS): Add runtime-po.
7981 (aclocaldir, aclocal_DATA): New variables.
7982 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
7983 Define aclocaldir.
7984 * src/getargs.c (usage): Document --print-localedir option.
7985 (PRINT_LOCALEDIR_OPTION): New enum item.
7986 (long_options): Add --print-localedir option.
7987 (getargs): Handle --print-localedir option.
7988 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
7989 (Internationalization): New section.
7990
7991 2005-07-12 Akim Demaille <akim@epita.fr>
7992
7993 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
7994 for consistency with the rest of the code.
7995 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
7996 Add separators.
7997
7998 2005-07-12 Akim Demaille <akim@epita.fr>
7999
8000 * src/parse-gram.y: Use %printer instead of YYPRINT.
8001
8002 2005-07-12 Akim Demaille <akim@epita.fr>
8003
8004 * src/symtab.h, src/symtab.c (symbol_print): New.
8005 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8006 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8007
8008 2005-07-12 Akim Demaille <akim@epita.fr>
8009
8010 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8011 b4_at_dollar and b4_dollar_dollar.
8012
8013 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8014
8015 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8016 and Pennello's paper.
8017
8018 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8019
8020 * data/yacc.c (yyparse): Undo previous patch. Instead,
8021 set yylsp[0] and yyvsp[0] only if the initial action
8022 sets yylloc and yylval, respectively.
8023
8024 * data/yacc.c (yyparse): In the initial action, set
8025 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8026 This avoids the use of undefined variables if the initial
8027 action does not set yylloc and/or yylval.
8028
8029 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8030
8031 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8032 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8033 Remove from CVS. These files are automatically generated.
8034 * examples/extexi: Clarify that this file is now part of Bison,
8035 not GNU M4, and that it works with any POSIX-compatible Awk.
8036 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8037 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8038 so that we also get calc++-parser.yy. Geneate it.
8039 Use $(AWK), not gawk, since any conforming Awk will do.
8040 Put comment before action, since older 'make' can't handle comment
8041 in action.
8042 $(BUILT_SOURCES): List all built sources, not just some of them.
8043 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8044 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8045 $($(calc_sources_generated)): Remove unnecessary test for existence
8046 of target. (This had a shell syntax error anyway; a stray "x".)
8047 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8048 calc++-parser.yy.
8049 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8050
8051 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8052 implied by the other modules.
8053
8054 2005-07-06 Akim Demaille <akim@epita.fr>
8055
8056 Bind examples/calc++ to the package.
8057 * examples/calc++/Makefile: Remove, replaced by...
8058 * examples/calc++/Makefile.am: ... this new file.
8059 * examples/calc++/test: Remove input.
8060 * examples/calc++/compile: Remove.
8061 * examples/Makefile.am: New.
8062 * configure.ac, Makefile.am: Adjust.
8063 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
8064
8065 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8066
8067 * data/glr.c (yyFail): Drastically simplify; since the format argument
8068 never had any % directives, we can simply pass it to yyerror.
8069 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8070 be modified later, as that is the usual style in glr.c.
8071 Problems reported by Paul Hilfinger.
8072
8073 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8074 and size overflow errors.
8075 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8076 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8077 (YYSIZEMAX): New macro.
8078 (yystpcpy): New function, taken from yacc.c.
8079 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8080 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8081 so that we don't have to maintain their signatures.
8082 (yyFail): Check for buffer overflow, by using vsnprintf rather
8083 than vsprintf. Allocate a bigger buffer if possible.
8084 Report an error if buffer allocation fails.
8085 (yyStackOverflow): New function.
8086 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8087 the initialization was successful. It might fail if storage was
8088 exhausted.
8089 (yyexpandGLRStack): Add more checks for storage allocation failure.
8090 Use yyStackOverflow to report failures.
8091 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8092 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8093 Don't assume stack number fits in int.
8094 (yysplitStack): Check for storage allocation failure.
8095 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8096 can print diagnostics on storage allocation failure. All callers
8097 changed.
8098 (yyresolveValue): Use yybool for boolean.
8099 (yyreportSyntaxError): Check for size-calculation overflow.
8100 This code is taken from yacc.c.
8101 (yyparse): Check for storage allocation errors when allocating
8102 the initial stack.
8103
8104 2005-07-05 Akim Demaille <akim@epita.fr>
8105
8106 Extract calc++ from the documentation.
8107 * doc/bison.texinfo (Calc++): Add the extraction marks.
8108 * examples/extexi: New, from the aborted GNU Programming 2E.
8109 Separate the different paragraph of a file with empty lines.
8110 * examples/Makefile: Use it to extract the whole calc++ example.
8111
8112 2005-06-24 Akim Demaille <akim@epita.fr>
8113
8114 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
8115 class typedefs.
8116
8117 2005-06-22 Akim Demaille <akim@epita.fr>
8118
8119 * doc/bison.texinfo (C++ Language Interface): First stab.
8120 (C++ Parsers): Remove.
8121
8122 2005-06-22 Akim Demaille <akim@epita.fr>
8123
8124 * data/lalr1.cc (yylex_): Honor %lex-param.
8125
8126 2005-06-22 Akim Demaille <akim@epita.fr>
8127
8128 Start a set of simple examples.
8129 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
8130 * examples/calc++/calc++-driver.hh,
8131 * examples/calc++/calc++-parser.yy,
8132 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
8133 * examples/calc++/compile, examples/calc++/test: New.
8134
8135 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8136
8137 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8138 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8139 which stems from the 2005-05-27 patch.
8140
8141 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8142
8143 * data/glr.c: Modify treatment of unused parameters to permit use
8144 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8145
8146 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8147
8148 Fix infringement on user name space reported by Janos Zoltan Szabo.
8149 * data/yacc.c (yyparse): strlen -> yystrlen.
8150
8151 2005-05-30 Akim Demaille <akim@epita.fr>
8152
8153 * data/lalr1.cc (_): New.
8154 Translate the various messages.
8155
8156 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8157
8158 Fix infringement on user name space reported by Bruno Haible.
8159 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8160 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8161 the user's name space.
8162 (alloca): Include <stdlib.h> to get it, if it's not built in.
8163 (YYMALLOC, YYFREE): Define only if needed.
8164 (malloc, free): Declare, but only if needed, as this infringes on
8165 the user name space.
8166
8167 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8168
8169 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8170 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8171 with %d format.
8172 * lib/ebitset.c (min, max): Undef before defining.
8173 * lib/vbitset.c (min, max): Likewise.
8174 * lib/subpipe.c (create_subpipe): Save local variables in case
8175 vfork clobbers them.
8176
8177 2005-05-24 Bruno Haible <bruno@clisp.org>
8178
8179 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
8180 error message syntax used by gcc-4.0.
8181
8182 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
8183
8184 * README: Mention m4 1.4.3. Remove obsolete advice about
8185 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8186
8187 * bootstrap: Remove workaround for problem I encountered with
8188 gettext 0.14.1; it seems to be fixed now.
8189
8190 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
8191
8192 * NEWS: Version 2.0a.
8193
8194 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8195 the previous change.
8196
8197 Various maintainer cleanups.
8198 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8199 conftest*, for benefit of CVS commands run at the same time as
8200 "configure". Add build-aux, since "bootstrap" now creates it and
8201 its subfiles.
8202 * Makefile.cfg (move_if_change): Remove.
8203 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
8204 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
8205 (po_repo, do-po-update, po-update, wget_files, get-targets):
8206 (config.guess-url_prefix, config.sub-url_prefix):
8207 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):

8209 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
8210 Remove.
8211 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
8212 this is now the recommended name.
8213 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
8214 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
8215 ylwrap. These files now go into build-aux.
8216 * config/move-if-change: Remove.
8217 * config/prev-version.txt: Bump from 1.75 to 2.0.
8218
8219 * bootstrap: Add stdio-safer, unistd-safer modules.
8220 Remove m4/glibc2.m4 (introduced by latest gnulib, but
8221 we don't need it).
8222 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
8223 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8224 * lib/subpipe.c: Include "unistd-safer.h".
8225 (create_subpipe): Make sure all the newly-created
8226 file descriptors are > 2, so that diagnostics don't
8227 get sent down them (which might cause Bison to hang, in theory).
8228 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8229 * src/files.c (xfopen): Use fopen_safer, not fopen.
8230
8231 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8232 yesterday's yacc.c fix.
8233
8234 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8235
8236 * data/glr.c, data/lalr1.cc: Update copyright date.
8237
8238 Fix a destructor bug reported by Wolfgang Spraul in
8239 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8240 * data/yacc.c (yyabortlab): Don't call destructor, and
8241 don't set yychar to EMPTY.
8242 (yyoverflowlab): Don't call destructor.
8243 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8244 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8245 since we no longer output the message "discarding lookahead token
8246 end of input ()".
8247
8248 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8249
8250 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8251 fix a small glitch in debugging output.
8252 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8253 after YY_SYMBOL_PRINT where needed.
8254
8255 (struct yyGLRState): Add some comments.
8256 (struct yySemanticOption): Add some comments.
8257 (union yyGLRStackItem): Add comment.
8258
8259 (yymergeOptionSets): Correct this to properly perform the union,
8260 avoiding infinite reported by Michael Rosien.
8261 Update comment.
8262
8263 * tests/glr-regression.at: Add test for GLR merging error reported
8264 by M. Rosien.
8265
8266 2005-05-13 Paul Eggert <eggert@cs.ucla.edu>

8303
8304 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8305
8306 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8307 Problem reported by Ralf Menzel.
8308
8309 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8310
8311 * tests/actions.at: Test that stack overflow invokes destructors.
8312 From Marcus Holland-Moritz.
8313 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8314 from here....
8315 (yyreturn): to here. That way, destructors are called properly
8316 even if the stack overflows, or the user calls YYACCEPT or
8317 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8318 (yyoverflowlab): Destroy the lookahead.
8319
8320 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8321
8322 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8323
8324 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8325
8326 * NEWS: Bison-generated C parsers no longer quote literal strings
8327 associated with tokens.
8328 * src/output.c (prepare_symbols): Don't escape strings,
8329 since users don't want to see C escapes.
8330 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8331 in diagnostics.
8332 * tests/input.at (Torturing the Scanner): Likewise.
8333 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8334
8335 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8336
8337 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8338 the data size is known to be too small and we can't increase it.
8339 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8340
8341 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8342
8343 * src/parse-gram.y: Include quotearg.h.
8344 (string_as_id): Quote $1 before using it as a key, since the
8345 lexer no longer quotes it for us.
8346 (string_content): Don't strip quotes, since lexer no longer
8347 quotes it for us.
8348 * src/scan-gram.l: Include quotearg.h.
8349 ("\""): Omit quote.
8350 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8351 a key, since the rest of the lexer doesn't quote it.
8352 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8353 * tests/regression.at (Token definitions): Check for backslashes
8354 in token strings.
8355
8356 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8357 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8358 (yyparse): Revamp code to generate long syntax error message, to
8359 make it easier to translate, and to avoid problems with arithmetic
8360 overflow. Change "virtual memory" to "memory" in diagnostic, since
8361 we don't know whether the memory is virtual.
8362
8363 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8364
8365 * NEWS: Bison-generated C parsers now use the _ macro to
8366 translate strings.
8367 * data/yacc.c (_) [!defined _]: New macro.
8368 All English strings wrapped inside this macro.
8369 * doc/bison.texinfo (Bison Parser): Document _.
8370 * po/POTFILES.in: Include src/parse-gram.c, since it now
8371 includes translateable strings that parse-gram.y doesn't.
8372
8373 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8374
8375 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8376 reverting the 2004-10-11 change to this function.
8377 (symbol_check_alias_consistency): Don't call symbol_type_set
8378 if the type name is already correct.
8379 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8380
8381 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8382
8383 * tests/regression.at (Token definitions): Don't use a token named
8384 c, as that generates a "#define c ..." that runs afoul of buggy
8385 stdlib.h that uses the identifier c as a member of struct
8386 drand48_data. Problem reported by Horst Wente.
8387
8388 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8389
8390 * bootstrap: Change translation URL from
8391 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8392 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8393 redirection glitches. Problem reported by twlevo@xs4all.nl.
8394
8395 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8396
8397 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8398 after operands; POSIX says this isn't portable for the c99 command.
8399
8400 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8401
8402 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8403 immediately if a data overrun has occurred; this may help us track
8404 down what may be a spurious failure on MacOS.
8405
8406 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8407
8408 Respond to problems reported by twlevo@xs4all.nl.
8409
8410 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8411
8412 * src/vcg.h: Comment fix.
8413 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8414 (G_CMAX): Change to -1 instead of INT_MAX.
8415
8416 * data/yacc.c (yyparse): Omit spaces before #line.
8417
8418 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8419
8420 * src/tables.c (state_number_to_vector_number): Put it inside an
8421 "#if 0", since it's not currently used. Problem reported by
8422 Roland McGrath.
8423
8424 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8425
8426 * src/output.c (escaped_output): Renamed from
8427 escaped_file_name_output, since we now use it for symbol tags as
8428 well. All uses changed.
8429 (symbol_destructors_output, symbol_printers_output):
8430 Escape symbol tags too.
8431 Problem reported by Matyas Forstner in
8432 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8433
8434 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8435 not needed.
8436 * src/output.c (user_actions_output, token_definitions_output,
8437 symbol_destructors_output, symbol_printers_output): Likewise.
8438 * src/reader.c (prologue_augment): Likewise.
8439 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8440
8441 * src/vcg.c (output_edge): Don't quote linestyle arg.
8442 Problem reported by twlevo@xs4all.nl.
8443
8444 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8445
8446 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8447 example, reported by Derek M Jones. Also, make the example even
8448 more outrageous, to better illustrate how bad the problem is.
8449
8450 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8451
8452 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8453 putsym. Typo reported by Sebastian Piping.
8454
8455 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8456
8457 * doc/bison.texinfo (Language and Grammar): some -> same
8458 (Epilogue): int he -> in the
8459 Typos reported by Sebastian Piping via Justin Pence.
8460
8461 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8462
8463 * tests/glr-regression.at (Improper handling of embedded actions
8464 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8465 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8466 with dollar signs in test names.
8467 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8468 for a similar reason.
8469
8470 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8471
8472 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8473 wants to redefine G_VIEW.
8474
8475 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8476
8477 * src/vcg.c (get_view_str): Remove case for normal_view.
8478 Problem reported by twlevo@xs4all.nl.

8480 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8481
8482 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8483 Problem reported by twlevo@xs4all.nl.
8484
8485 * doc/bison.texinfo: Change @dircategory from "GNU programming
8486 tools" to "Software development". Requested by Richard Stallman
8487 via Karl Berry.
8488
8489 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8490
8491 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8492 Problem reported by twlevo@xs4all.nl.
8493
8494 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8495
8496 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8497 keyword; it's not needed with modern compilers, and it doesn't
8498 affect correctness with older compilers. Suggested by
8499 twlevo@xs4all.nl.
8500
8501 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8502
8503 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8504 gcc -Wswitch-default.

8508 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8509
8510 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8511 already. Let config.h define any nonstandard values.
8512
8513 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8514
8515 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8516 for the benefit of slower hosts. Problem reported by
8517 Nelson H. F. Beebe.
8518
8519 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8520
8521 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8522 being defined and not used.
8523 * data/lalr1.cc (yyparse): Likewise.
8524 Use "if (false)" rather than "if (0)".
8525
8526 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8527
8528 * TODO: Mention that we should allow NUL bytes in tokens.

8530 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8531
8532 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8533 Problem reported by Hans Aberg.
8534
8535 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8536
8537 * src/getargs.c (version): Happy new year; update overall
8538 program copyright date from 2004 to 2005.
8539
8540 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8541 Problem reported by Hans Aberg.
8542 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8543 (Output file names.): Add a test for the case when standard output
8544 is closed.
8545
8546 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8547
8548 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8549 to fix an oversight in the Bison 2.0 manual.
8550
8551 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8552
8553 * NEWS: Version 2.0. Reformat the existing news items since
8554 1.875, so that related items are grouped together.
8555 * configure.ac (AC_INIT): Bump version to 2.0.
8556 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8557
8558 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8559 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8560 otherwise, we're not testing alloca. Unfortunately there's no
8561 simple way to consult HAVE_ALLOCA here.
8562
8563 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8564 for yymsg, too.
8565
8566 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8567 hand. This avoids a warning about comparing int to size_t when
8568 GCC warnings are enabled.
8569
8570 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8571
8572 * NEWS: Bison-generated parsers no longer default to using the
8573 alloca function (when available) to extend the parser stack, due
8574 to widespread problems in unchecked stack-overflow detection.
8575 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8576 responsibility to set it to a positive value. This lets the user
8577 specify a value that is not a preprocessor constant.
8578 * data/yacc.c (YYMAXDEPTH): Likewise.
8579 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8580 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8581 to be a compile-time constant. However, explain the constraints on it.
8582 Also, explain the constraints on YYINITDEPTH.
8583 (Table of Symbols): Explain that alloca is no longer the default.
8584 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8585 to 1.
8586
8587 * doc/bison.texinfo (Location Default Action): Mention that n must
8588 be zero when k is zero. Suggested by Frank Heckenbach.
8589
8590 2004-12-22 Akim Demaille <akim@epita.fr>
8591
8592 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8593 (parser::state_type, parser::semantic_type, parser::location_type):
8594 Private, not public.
8595 (parser::parse): Return ints, not bool.
8596 Returning a bool introduces a problem: 0 corresponds to false, and
8597 it seems weird to return false on success. Returning true changes
8598 the conventions for yyparse.
8599 Alternatively we could return void and send an exception.
8600 There is no clear consensus (yet?).
8601 (state_stack, semantic_stack, location_stack): Rename as...
8602 (state_stack_type, semantic_stack_type, location_stack_type): these.
8603 Private, not public.
8604 * tests/c++.at: New.
8605 * tests/testsuite.at, tests/Makefile.am: Adjust.
8606
8607 2004-12-21 Akim Demaille <akim@epita.fr>
8608
8609 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8610
8611 2004-12-21 Akim Demaille <akim@epita.fr>
8612
8613 Don't impose std::string for filenames.
8614
8615 * data/lalr1.cc (b4_filename_type): New.
8616 (position::filename): Use it.
8617 (parser.hh): Move the inclusion of stack.hh and location.hh below
8618 the user code, so that needed headers for the filename type can be
8619 included first.
8620 Forward declare them before the user code.
8621 * tests/Makefile.am (check-local, installcheck-local): Pass
8622 TESTSUITEFLAGS to the TESTSUITE.
8623
8624 2004-12-20 Akim Demaille <akim@epita.fr>
8625
8626 Use more STL like names: my_class instead of MyClass.
8627
8628 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8629 (SemanticStack, SemanticType, StateStack, StateType)
8630 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8631 (Parser::value): Rename as...
8632 (location_stack, location_type, rhs_number_type, semantic_stack)
8633 (semantic_type, state_stack, state_type, token_number_type, stack)
8634 (slice, traits, parser::yylloc, parser::yylval): these.
8635
8636 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8637
8638 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8639
8640 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8641 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8642
8643 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8644
8645 Remove uses of 'short int' and 'unsigned short int'. This raises
8646 some arbitrary limits. It uses more memory but nowadays that's
8647 not much of an issue.
8648
8649 This change does not affect the generated parsers; that's a different
8650 task, as some users will want to conserve memory there.
8651
8652 Ideally we should use size_t to represent all object counts, and
8653 something like ptrdiff_t to represent signed differences of object
8654 counts; but that will require more code-cleanup than I have the
8655 time to do right now.
8656
8657 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
8658 Use size_t, not int or short int, to count objects.
8659 * src/closure.c (nritemset, closure): Likewise.
8660 * src/closure.h (nritemset, closure): Likewise.
8661 * src/nullable.c (nullable_compute): Likewise.

8666 * src/tables.c (default_goto, goto_actions): Likewise.
8667
8668 * src/gram.h (rule_number, rule): Use int, not short int.
8669 * src/output.c (prepare_rules): Likewise.
8670 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
8671 errs, reductions): Likewise.
8672 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
8673 Likewise.
8674 * src/tables.c (vector_number, tally, action_number,
8675 ACTION_NUMBER_MINIMUM): Likewise.
8676 * src/output.c (muscle_insert_short_int_table): Remove.
8677
8678 2004-12-17 Akim Demaille <akim@epita.fr>
8679
8680 * data/lalr1.cc: Extensive Doxygenation.
8681 (error_): Rename as...
8682 (error): this, since it is visible to the user.
8683 Adjust callers.
8684 (Parser::message): Now an automatic variable from...
8685 (Parser::yyreport_syntax_error_): here.
8686 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
8687 Parser::error.
8688 * tests/input.at: Escape $.
8689
8690 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
8691
8692 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
8693 Parenthesize rhs to avoid obscure problems with mistakes like
8694 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
8695 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8696 b4_rhs_location): Likewise.
8697 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
8698 b4_rhs_location): Likewise.
8699
8700 2004-12-16 Akim Demaille <akim@epita.fr>
8701
8702 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
8703 yacc.c: be sure to stay within yycheck_.
8704 * tests/actions.at: Re-enable C++ tests.
8705
8706 2004-12-16 Akim Demaille <akim@epita.fr>
8707
8708 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
8709 real.
8710
8711 2004-12-16 Akim Demaille <akim@epita.fr>
8712
8713 Use #define to handle the %name-prefix.
8714
8715 * data/glr.c, data/yacc.c: Comment changes.
8716 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
8717 so that one can refer to yylex in the parser file, and have it
8718 renamed, as is the case with other skeletons.
8719
8720 2004-12-16 Akim Demaille <akim@epita.fr>
8721
8722 Move lalr1.cc internals into yy*.

8742 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
8743
8744 Fix some problems reported by twlevo at xs4all.
8745 * src/symtab.c (symbol_new): Report an error if the input grammar
8746 contains too many symbols. This is better than calling abort() later.
8747 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
8748 (struct node, struct graph):
8749 Rename member expand to stretch. All uses changed.
8750 (struct graph): Remove member layoutalgorithm. All uses removed.
8751 * src/vcg.c (get_layoutalgorithm_str): Remove. All uses removed.
8752 * src/vcg_defaults.h (G_STRETCH): Renamed from G_EXPAND.
8753 All uses changed.
8754 (N_STRETCH): Rename from N_EXPAND. All uses changed.
8755
8756 2004-12-15 Akim Demaille <akim@epita.fr>
8757
8758 * data/lalr1.cc: Normalize /** \brief ... */ to ///.
8759 Add more Doxygen comments.
8760 (symprint_, stack_print_, reduce_print_, destruct_, pop)
8761 (report_syntax_error_, translate_): Rename as...
8762 (yysymprint_, yystack_print_, yyreduce_print_, yydestruct_)
8763 (yypop_, yyreport_syntax_error_, yytranslate_): this.
8764
8765 2004-12-15 Akim Demaille <akim@epita.fr>
8766
8767 * data/lalr1.cc (lex_): Rename as...
8768 (yylex_): this.
8769 Move the trace here.
8770 Take the %name-prefix into account.
8771 Reported by Alexandre Duret-Lutz.
8772
8773 2004-12-15 Akim Demaille <akim@epita.fr>
8774
8775 Simplify the C++ parser constructor.
8776
8777 * data/lalr1.cc (debug_): Rename as...
8778 (yydebug_): so that the parser's internals are always in the yy*
8779 pseudo namespace.
8780 Adjust uses.
8781 (b4_parse_param_decl): Remove the leading comma as it is now only
8782 called as unique argument list.
8783 (Parser::Parser): Remove the constructor accepting a location and
8784 an initial debugging level.
8785 Remove from the other ctor the argument for the debugging level.
8786 (debug_level_type, debug_level, set_debug_level): New.
8787
8788 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
8789 constructor calls.
8790
8791 2004-12-15 Akim Demaille <akim@epita.fr>
8792
8793 Remove b4_root related material: failure experiment
8794 (which goal was to allow to derive from a class).
8795
8796 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
8797 definitions and uses.
8798
8799 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
8800
8801 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
8802 not 2, since it's not portable to subtract 1 from the start of an
8803 array. The new item 0 is never set or used. All uses changed.
8804
8805 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
8806 the default definition of YYLLOC_DEFAULT. Problem reported
8807 by Frank Heckenbach.
8808
8809 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
8810
8811 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
8812 the normal case and one for the error case. Just use the
8813 first one uniformly. Problem reported by Frank Heckenbach.
8814 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
8815 use exactly the same macro in both places.
8816 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
8817 so that the normal-case YYRHSLOC works for the error case too.
8818 All uses changed.
8819 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
8820 (YYLLOC_DEFAULT): Use the same macro as glr.c.
8821 * doc/bison.texinfo (Location Default Action): Don't claim that
8822 we have an array of locations. Use the same macro for both glr
8823 and lalr parsers. Mention YYRHSLOC. Mention what happens when
8824 the index is 0.
8825
8826 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8827
8828 * HACKING: Update email addresses to send announcements to.
8829

8831
8832 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
8833
8834 * NEWS: Version 1.875e.
8835 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
8836
8837 * src/scan-skel.l: Include "complain.h", for "fatal".
8838
8839 * src/relation.h (relation_print, relation_digraph):
8840 Relation sizes are of type relation_node, not size_t (this is
8841 merely a doc fix, since the two types are equivalent).
8842 (relation_transpose): Relation sizes are of type relation_node,
8843 not int.
8844 * src/relation.c: Likewise.
8845 (top, infinity): Now of type relation_node, not int.
8846 (traverse, relation_transpose): Use relation_node, not int.
8847
8848 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
8849 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
8850 (yyparse): Remove unused local introduced in 2004-10-25 patch.
8851
8852 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
8853 specifying whether the test should be skipped. Use it tp
8854 specify that the [%defines %skeleton "lalr1.cc"] tests currently
8855 fail on some hosts, and should be skipped.
8856
8857 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
8858
8859 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
8860 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
8861 unless otherwise specified below.
8862
8863 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
8864 to allocate kernel_base, kernel_items, kernel_size, since
8865 they needn't be initialized to 0.
8866 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
8867 * src/closure.c (new_closure): Likewise, for itemset.
8868 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
8869 * src/lalr.c (set_goto_map): Likewise, for temp_map.
8870 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
8871 (build_relations): Likewise for edge, states1, includes.
8872 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
8873 * src/reader.c (packgram): Likewise, for ritem, rules.
8874 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.

8876 (relation_transpose): Likewise for new_R, end_R.
8877 * src/symtab.c (symbols_token_translations_init): Likewise for
8878 token_translations.
8879 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
8880 (token_actions): Likewise for yydefact, actrow, conflrow,
8881 conflict_list.
8882 (save_column): Likewise for froms[symno], tos[symno].
8883 (goto_actions): Likewise for state_count.
8884 (pack_table): Likewise for base, pos, check.
8885 (tables_generate): Likewise for width.
8886
8887 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
8888 for initial core. Just have a separate core, so we needn't worry
8889 about whether kernel_size and kernel_base are initialized.
8890
8891 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
8892 kernel_size, kernel_items): Remove unnecessary initialization.
8893 * src/conflicts.c (conflicts): Likewise.
8894 * src/derives.c (derives): Likewise.
8895 * src/muscle_tablc (muscle_insert): Likewise.
8896 * src/relation.c (relation_digraph): Likewise.
8897 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
8898 conflrow, conflict_table, conflict_list, table, check):
8899 Likewise.
8900
8901 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
8902 This is because all callers pass unsigned int.
8903 * src/closure.h (new_closure): Likewise.
8904
8905 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
8906 (build_relations): Initialize includes[i] in all cases.
8907 * src/reader.c (packgram): Always initialize rules[ruleno].prec
8908 and rules[ruleno].precsym. Initialize members in order.
8909 * src/relation.c (relation_transpose): Always initialize new_R[i]
8910 and end_R[i].
8911 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
8912
8913 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
8914 conflict_list[0] was always 0, but now it isn't initialized.
8915
8916 * src/table.c (table_grow): When conflict_table grew, the grown
8917 area wasn't cleared. Fix this.
8918
8919 * lib/.cvsignore: Add strdup.c, strdup.h.
8920 * m4/.cvsignore: Add strdup.m4.
8921
8922 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
8923
8924 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
8925 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
8926 GOTO_NUMBER_MAXIMUM, since we occasionally compute
8927 ngotos + 1 without checking for overflow.
8928 (build_relations): Use END_NODE, not -1, to denote end of edges.
8929 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
8930 build_relations): Use goto_number, not int, for goto numbers.
8931 * src/tables.c (save_column, default_goto): Likewise.
8932
8933 2004-11-23 Akim Demaille <akim@epita.fr>
8934
8935 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
8936 of #defining from yystype.
8937 Don't typedef yystype, C++ does not need it.
8938 This lets it possible to forward declare it as union.
8939
8940 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
8941
8942 * bootstrap (gnulib_modules): Add extensions.
8943 Problem reported by Jim Meyering.
8944
8945 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
8946
8947 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
8948 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
8949 src/system.h, src/tables.c: XFREE -> free, to accommodate
8950 recent change to gnulib xalloc.h.
8951 Problem reported by Jim Meyering.
8952
8953 2004-11-17 Akim Demaille <akim@epita.fr>
8954
8955 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
8956
8957 2004-11-17 Akim Demaille <akim@epita.fr>,
8958 Alexandre Duret-Lutz <adl@gnu.org>
8959
8960 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
8961 changes.
8962 (YYCDEBUG): Adjust.
8963 Use it instead of cdebug_.
8964 (Parser::debug_stream, Parser::set_debug_stream): New.
8965 (Parser::symprint_): Define cdebug_ for temporary backward
8966 compatibility.
8967 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
8968 debug_stream ().
8969
8970 2004-11-17 Akim Demaille <akim@epita.fr>
8971
8972 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
8973 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
8974 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
8975 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
8976
8977 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>

8980 Problem reported by Frank Heckenbach.
8981
8982 2004-10-25 Akim Demaille <akim@epita.fr>
8983
8984 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
8985 Introduce another definition to address simple location arrays.
8986 (yyGLRStack): New member: yyerror_range.
8987 (yyrecoverSyntaxError, yyparse): Update it.
8988 (yyrecoverSyntaxError): Use it when shifting the error token to
8989 have an accurate range, equivalent to the one computed by both
8990 yacc.c and lalr1.cc.
8991 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
8992 that column numbers start at column 0, as per GNU Coding
8993 Standards, the others tests, and the doc.
8994 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
8995 Adjust to the above change (first column is 0).
8996 And adjust the location of the "<error>", now covering the whole
8997 line.
8998
8999 2004-10-22 Akim Demaille <akim@epita.fr>
9000 and Paul Eggert <eggert@cs.ucla.edu>
9001
9002 Remove some arbitrary limits on goto numbers and relations.
9003 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9004 initial values, since they're never used.
9005 (set_goto_map): ngotos is now unsigned, so test for overflow
9006 by seeing whether it wraps around to zero.
9007 * src/lalr.h (goto_number): Now size_t, not short int.
9008 (GOTO_NUMBER_MAXIMUM): Remove.
9009 * src/relation.c (relation_print, traverse, relation_transpose):
9010 Check for END_NODE rather than looking at sign.
9011 * src/relation.h (END_NODE): New macro.
9012 (relation_node): Now size_t, not short int.
9013
9014 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9015
9016 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9017 keyword, not an identifier. Problem reported by Baron Schwartz in
9018 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9019
9020 2004-10-11 Akim Demaille <akim@epita.fr>
9021
9022 * src/symtab.c (symbol_check_alias_consistency): Also check
9023 type names, destructors, and printers.
9024 Reported by Alexandre Duret-Lutz.
9025 Recode the handling of associativity and precedence in terms
9026 of symbol_precedence_set.
9027 Accept no redeclaration at all, not even equal to the previous
9028 value.
9029 (redeclaration): New.
9030 Use it to factor redeclaration complaints.
9031 (symbol_make_alias): Don't set the type of the alias, let
9032 symbol_check_alias_consistency do it as for other features.
9033 * src/symtab.h (symbol): Add new member prec_location, and
9034 type_location.
9035 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9036 * tests/input.at (Incompatible Aliases): New.
9037
9038 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9039
9040 .cvsignore fixes to accommodate gnulib changes,
9041 and the practice of naming build directories "_build".
9042 * .cvsignore: Add "_*". Sort.
9043 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9044 * m4/.cvsignore: Add "*_gl.m4".
9045
9046 2004-10-06 Akim Demaille <akim@epita.fr>
9047
9048 * src/parse-gram.y (add_param): Fix the truncation of trailing
9049 spaces.
9050
9051 2004-10-05 Akim Demaille <akim@epita.fr>
9052
9053 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9054 whether the reducion was empty or not. This leaves room to
9055 improve the use of YYLLOC_DEFAULT in such a case.
9056 lalr1.cc is still experimental, so changing this is acceptable.
9057 And finally, there are probably not many users who changed the
9058 handling of locations in GLR, so changing is admissible too.
9059
9060 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9061 empty reduction, set @$ to an empty location ending the previously
9062 stacked symbol.
9063 Adjust uses to make sure the code is triggered on empty
9064 reductions.
9065 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9066 expected output: empty reductions have empty locations.
9067
9068 2004-09-29 Akim Demaille <akim@epita.fr>
9069
9070 * data/lalr1.cc: Move towards a more standard C++ coding style
9071 for templates: Class < T > -> Class<T>.
9072
9073 2004-09-29 Akim Demaille <akim@epita.fr>
9074
9075 * data/lalr1.cc: Reinstall the former ctor, for sake of
9076 compatibility, but warn it will be removed.
9077 Move towards a more standard C++ coding style (i.e., type *var ->
9078 type* var).
9079
9080 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9081
9082 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9083 since it's less likely to work if NULs are involved in the future.
9084
9085 2004-09-27 Akim Demaille <akim@epita.fr>
9086
9087 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9088
9089 2004-09-27 Akim Demaille <akim@epita.fr>
9090
9091 * data/lalr1.cc (b4_parse_param_decl_1): New.
9092 (b4_parse_param_decl): Use it to have different names between attribute
9093 and argument names.
9094 (b4_cc_constructor_call): Likewise.
9095
9096 2004-09-24 Akim Demaille <akim@epita.fr>
9097

9099 blanks from a formal argument declaration.
9100 (YY_LOCATION_PRINT): New.
9101
9102 2004-09-24 Akim Demaille <akim@epita.fr>
9103
9104 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9105 after the location.
9106
9107 2004-09-24 Akim Demaille <akim@epita.fr>
9108
9109 * doc/bison.texinfo (Table of Symbols): Sort.
9110
9111 2004-09-21 Akim Demaille <akim@epita.fr>
9112
9113 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9114 the useless parentheses.
9115 Suggested by Paul Eggert.
9116
9117 2004-09-20 Akim Demaille <akim@epita.fr>
9118
9119 Let the initial-action act on the look-ahead, and use it for the
9120 "initial push" (corresponding to an hypothetical beginning-of-file).
9121 And let lalr1.cc honor %initial-action.
9122
9123 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9124 example.
9125 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9126 (Parser::Parser): Remove the ctor that used to initialize it.
9127 (Parser::parse): Like in the other skeletons, issue the "starting
9128 parse" message before any action.
9129 Honor %initial-action.
9130 Initialize the stacks with the lookahead.
9131 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9132 look-ahead.
9133 Push them in the stacks.
9134 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9135
9136 2004-09-20 Akim Demaille <akim@epita.fr>
9137
9138 * doc/bison.texinfo (Initial Action Decl): New.
9139
9140 2004-09-20 Akim Demaille <akim@epita.fr>
9141
9142 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9143 clearer criterion to define it.
9144 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9145 When reducing on an empty RHS, use the latest stacked location as
9146 location.
9147 yylloc is not always available.
9148 * data/glr.c: Likewise.
9149 Also, honor initial-actions.
9150
9151 2004-09-20 Akim Demaille <akim@epita.fr>
9152
9153 * data/yacc.c (YY_LOCATION_PRINT): New.
9154 Define when we know YYLTYPE's structure, i.e., when the default
9155 YYLLOC_DEFAULT is used.
9156 * data/c.m4 (b4_yysymprint_generate): Use it.
9157 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9158 value of the result.
9159 (error_start_): Replace with...
9160 (error_range_): this location array.
9161 This allows to replace code relying on the implementation of
9162 locations by portable code.
9163 * data/yacc.c (yylerrsp): Replace with...
9164 (yyerror_range): this.
9165 Every time a token is popped, update yyerror_range[0], to have an
9166 accurate location for the error token.
9167 * data/glr.c (YY_LOCATION_PRINT): New.
9168 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9169 deference a pointer.
9170 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9171 report the location in %printers.
9172
9173 * src/scan-skel.l: Instead of abort, report error messages to ease
9174 understanding skeleton scanning failures.
9175
9176 2004-09-16 Akim Demaille <akim@epita.fr>
9177
9178 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9179 (iterator, const_iterator): these, to be more in the C++ spirit.
9180 Also, return reverse iterators so that when displaying the stack
9181 we display its bottom first.
9182 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9183 from yacc.c.
9184 We should probably use vector here though.
9185
9186 2004-09-16 Akim Demaille <akim@epita.fr>
9187
9188 Have more complete shift traces.
9189
9190 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9191 to report Shifts instead of ad hoc YYDPRINTF invocations,
9192 including for the error token.
9193 * data/lalr1.cc (symprint_): Output the location.
9194 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9195 output the location within the %printer.
9196 Activate GLR tests, at least to make sure they compile properly.
9197 They still don't pass though.
9198 * tests/calc.at: Adjust expect verbose output, since now "Entering
9199 state..." is on a different line than the "Shifting" message.
9200
9201 2004-09-08 Akim Demaille <akim@epita.fr>
9202
9203 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9204 Bison directive from the Bison file to the invocation of this
9205 macro, so that these directives are passed to
9206 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9207 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9208 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9209 the extra Bison directives instead of the whole series.
9210 Change the grammar so that there are recoverable errors, and
9211 unrecoverable errors. Now we can have the parser give up before
9212 consuming the whole input. As a result we now can observe that
9213 the lookahead is freed when needed.
9214 Change the parser source to parse argv[1] instead of a hard coded
9215 string.
9216 Simplify yylex, and give a value and location to EOF.
9217 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9218 passed directives already coded in the file.
9219 Add some tests to check the location of "error".
9220 For some tests, the C++ parser is correct, and not yacc.c.
9221 For other tests, they provide different, but unsatisfying, values,
9222 so keep the C++ value so that at least one parser is "correct"
9223 according to the test suite.
9224 (Actions after errors): Remove, this is subsumed by the
9225 AT_CHECK_PRINTER_AND_DESTRUCTOR series.
9226
9227 2004-09-06 Akim Demaille <akim@epita.fr>
9228
9229 * data/lalr1.cc: Adjust the indentation of the labels.
9230 (Parser::pop): New.
9231 Use it.
9232
9233 2004-09-06 Akim Demaille <akim@epita.fr>
9234
9235 * data/yacc.cc, data/glr.cc (yydestruct): Accept an additional
9236 argument, an informative message.
9237 Call YY_SYMBOL_PRINT.
9238 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9239 * data/lalr1.cc (destruct_): Likewise.
9240 In addition, no longer depend on b4_yysymprint_generate and
9241 b4_yydestruct_generate to generate these functions, do it "by
9242 hand".
9243
9244 2004-09-03 Akim Demaille <akim@epita.fr>
9245
9246 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9247 invoked, yydestruct the lookahead.
9248 * tests/calc.at (Calculator $1): Update the expected lengths of
9249 traces: there is an added line for the discarded lookahead.
9250 * doc/bison.texinfo (Destructor Decl): Some rewording.
9251 Define "discarded" symbols.
9252
9253 2004-09-02 Akim Demaille <akim@epita.fr>
9254
9255 * data/lalr1.cc (translate_, destruct_): No reason to be static.
9256
9257 2004-09-02 Akim Demaille <akim@epita.fr>
9258
9259 * data/glr.c, yacc.c (YYDSYMPRINT): Remove, not used.
9260 (YYDSYMPRINTF): Rename as...
9261 (YY_SYMBOL_PRINT): this.
9262 * data/lalr1.cc (YY_SYMBOL_PRINT): New, modeled after the previous
9263 two.
9264 Use it instead of direct symprint_ calls.
9265 (yybackup): Tweak the "Now at end of input" case to match yacc.c's
9266 one.
9267
9268 2004-09-02 Akim Demaille <akim@epita.fr>
9269
9270 * data/lalr1.cc (b4_yysymprint_generate): New.
9271 (symprint_): New member function, defined when YYDEBUG.
9272 Use it consistently instead of token/nterm debugging output by
9273 hand.
9274 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
9275 %printer calls to use cdebug_ when using lalr1.cc.
9276
9277 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9278
9279 * data/glr.c: Guard the declarations of yypstack and yypdumpstack
9280 with #ifdef YYDEBUG.
9281
9282 2004-08-26 Akim Demaille <akim@epita.fr>
9283
9284 * doc/bison.texinfo (Implementing Loops): Rename as...
9285 (Implementing Gotos/Loops): this.
9286
9287 2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
9288
9289 Adjust to latest gnulib.
9290 * bootstrap (gnulib_modules): Add xalloc-die.
9291 Set LC_ALL=C so that file names sort consistently.
9292 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9293 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9294 uintmax_t.m4, ulonglong.m4.
9295 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9296 po.m4 since we are now using _gl.m4 instead.
9297
9298 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9299
9300 * src/scan-action.l: Remove. Scanning of semantic actions is
9301 handled in scan-gram.l.
9302
9303 2004-08-07 Florian Krohm <florian@edamail.fishkill.ibm.com>
9304
9305 * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.
9306
9307 * src/location.h (struct): The file member is a uniqstr.
9308 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9309
9310 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9311
9312 Fix bug with non-%union parsers that have printers or destructors,
9313 which led to a Bison core dump. Reported by Peter Fales in
9314 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9315
9316 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9317 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9318 not to our own type.
9319 * src/output.c (symbol_destructors_output, symbol_printers_output):
9320 Don't assume %union.
9321 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9322 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9323 UNION-FLAG. All callers changed.
9324 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9325 Use type char, not unsigned int, when declaring an array of char;
9326 this lets us remove a cast.
9327 (Printers and Destructors): Add non-%union test cases.
9328
9329 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9330
9331 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9332 GLR writeups. E.g., avoid frenchspacing and the future tense,
9333 change "lookahead" to "look-ahead", and change "wrt" to "with
9334 respect to".
9335
9336 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9337
9338 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9339 New sections, split off from the GLR Parsers section. Put the new
9340 Simple GLR Parser near the start of the GLR section, for clarity.
9341 Rewrite connective text.
9342
9343 2004-06-21 Frank Heckenbach <frank@g-n-u.de>
9344

9346
9347 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9348
9349 * NEWS, TODO, doc/bison.texinfo:
9350 Use "look-ahead" instead of "lookahead", to be consistent.
9351 * REFERENCES: Fix incorrect reference to DeRemer and Pennello,
9352 while we're fixing "look-ahead".
9353 * src/conflicts.c (shift_set): Renamed from shiftset.
9354 (look_ahead_set): Renamed from lookaheadset.
9355 * src/print.c: Likewise.

9374 * README: Update location of patched M4 distribution.
9375
9376 2004-05-30 Albert Chin-A-Young <china@thewrittenword.com>
9377
9378 Don't assume the C++ compiler takes the same arguments as the C compiler
9379 (trivial change).
9380 * configure.ac (O0CXXFLAGS): New var.
9381 * tests/atlocal.in (CXXFLAGS): Use it.
9382
9383 2004-05-29 Paul Eggert <eggert@cs.ucla.edu>
9384
9385 Fix some "make check" problems with C++ reported by

9387 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00049.html
9388
9389 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check for std::cerr.
9390 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
9391 Output to a .cc file for C++, not to a .c file.
9392 * tests/calc.at (AT_CHECK_CALC): Likewise.
9393 * tests/regression.at (AT_CHECK_DANCER): Likewise.
9394 * tests/local.at (AT_COMPILE_CXX): Default to OUTPUT.cc, not OUTPUT.c.
9395

9400
9401 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9402
9403 Spent a few hours checking out which prerequisite versions the
9404 current sources actually require. I went all the way back to
9405 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9406 a seemingly endless set of combinations of versions more recent
9407 than that. The bottom line is that the current sources require
9408 fairly recent versions of the build tools, and it'll be some work
9409 to change this.
9410 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9411 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9412 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9413 Add comments explaining why those particular versions are
9414 currently needed.
9415
9416 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9417 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9418 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9419
9420 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9421 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9422
9423 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9424
9425 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9426 0.11.5. Suggested by Bruno Haible.
9427 * bootstrap: Remove gettext version checking.
9428
9429 * doc/bison.texinfo (Decl Summary): Also mention that %union
9430 can depend on prerequisite types. Problem reported by Tim
9431 Van Holder.
9432
9433 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9434
9435 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9436 * README-alpha: Don't tell people not to package this.
9437
9438 * bootstrap: Don't assume $(...) works; use `...` instead.
9439 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9440 gettext better.
9441
9442 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9443 put into the -d output file, and mention what to do if YYSTYPE is
9444 defined as a macro.
9445
9446 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9447
9448 Undo change made earlier today: it caused autopoint to not bring
9449 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9450 autopoint's.
9451
9452 * bootstrap: Check that gettext version matches what's in
9453 configure.ac. Warn users to ignore robots.txt ERROR 404.
9454 * bootstrap: Undo today's earlier change (logged below).
9455 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9456
9457 The gettext version checking is causing more trouble than it's
9458 curing; remove it. Problem reported by Paul Hilfinger.
9459
9460 * bootstrap: Issue a warning that one can expect a message
9461 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9462 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9463
9464 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9465
9466 Ensure that the C++ compiler used for testing actually works on a
9467 simple test program; if not, skip the C++-related tests. Problem
9468 reported by Vin Shelton in:
9469 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9470
9471 * m4/cxx.m4: New file.
9472 * configure.ac (BISON_TEST_FOR_WORKING_CXX_COMPILER): Add.
9473 * tests/atlocal.in (BISON_CXX_WORKS): Add.
9474 * tests/local.at (AT_COMPILE_CXX): Use it.
9475
9476 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9477
9478 * data/glr.c (yylloc): Output this macro even if locations are not
9479 being generated, as the GLR parser needs it even in that case.
9480 Problem reported by Troy A. Johnson
9481 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9482
9483 * configure.ac (AC_INIT): Update to 1.875e.
9484
9485 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9486
9487 * NEWS: Version 1.875d.
9488 * configure.ac (AC_INIT): Likewise.
9489 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
9490
9491 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9492 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9493 lalr1.cc runs afoul of the first, and the last two are no longer
9494 supported by GCC 3.4.0.
9495 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9496 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9497
9498 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
9499
9500 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
9501 unsigned int, for compatibility with latest gnulib hash module.

9503 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
9504 * src/uniqstr.c (hash_uniqstr): Likewise.
9505
9506 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9507
9508 * NEWS: Unescaped newlines are no longer allowed in char & strings.
9509
9510 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
9511 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
9512 character and string literals.
9513 (unexpected_end): New function.
9514 (unexpected_eof): Use it.
9515 (unexpected_newline): New function.
9516 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
9517 actions.
9518
9519 * NEWS: Document %expect-rr.
9520
9521 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
9522 Fix typo by replacing $1 with $option.
9523 Remove more 'intl'-related files.
9524 Don't DEFUN AM_INTL_SUBDIR twice.
9525
9526 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
9527 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
9528 strtoul.c.
9529 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
9530 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
9531 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
9532 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
9533 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9534 * src/.cvsignore: Add *.output.
9535
9536 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9537 gets copied to the output file.
9538
9539 2004-04-28 Paul Eggert <eggert@twinsun.com>
9540
9541 Get files from the gnulib and po repositories, instead of relying
9542 on them being in our CVS. Upgrade to latest versions of gnulib
9543 and Automake.
9544
9545 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9546 * bootstrap: Bootstrap from gnulib and po repositories.
9547 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9548 * README-cvs: Document these changes. Remove version numbers from
9549 mentions of build tools, since they change so often. Mention Flex.
9550
9551 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
9552 (gl_USE_SYSTEM_EXTENSIONS): Add.
9553 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9554 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9555 does this for us.
9556 (AC_ISC_POSIX): Remove; we no longer support this
9557 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9558 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9559 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9560 Do not check for C89 headers, except for locale.h which is used
9561 by the Yacc library and must port to K&R hosts.
9562 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9563 Do not check for C89 functions, except for setlocale which is
9564 used by the Yacc library.
9565 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
9566 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
9567 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,
9568 gl_GETOPT, gl_HASH, gl_MBSWIDTH, gl_OBSTACK, gl_QUOTE,
9569 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
9570 AM_GNU_GETTEXT): Remove; now done by:
9571 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
9572 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
9573 for us.
9574
9575 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9576 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9577 Define to empty, as gnulib.mk will do the rest for us.
9578 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
9579 for us.
9580 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.

9612 Remove, as these files are now generated automatically
9613 by bootstrap or automake.
9614
9615 * po/ChangeLog: Remove: all but one entry was a duplicate
9616 of this file, and I moved that 2000-11-02 entry here.
9617

9636
9637
9638 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
9639 support it. (The latest stable gzip doesn't.)
9640
9641 2004-04-27 Paul Eggert <eggert@twinsun.com>
9642
9643 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9644 case, as stos_ is now used by destructors due to the 2004-02-09
9645 change.
9646
9647 Remove more K&R C support.
9648 * lib/libiberty.y (PARAMS): Remove. All uses removed.
9649 * lib/subpipe.c (errno): Remove decl.
9650 Include <stdlib.h> unconditionally.
9651 (EXIT_FAILURE): Remove macro.
9652 * src/complain.c (vfprintf, strerror): Remove.

9665 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
9666 with latest obstack.h.
9667 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
9668 to procedure types, as obstack.h now does that for us.
9669 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
9670
9671 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
9672 so that this include file can stand alone.
9673 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
9674 does this now. Include subpipe.h first after config.h, to
9675 test whether it can stand alone.
9676
9677 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
9678 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
9679 unused declaration.
9680
9681 * tests/synclines.at (%union synch line): Put a dummy member in
9682 the union, because empty unions aren't allowed in C. Caught
9683 by GCC 3.4.0.

9685 2004-04-13 Jim Meyering <jim@meyering.net>
9686
9687 * src/conflicts.c (conflicts_print): Correct format string typo:

9689
9690 2004-03-30 Paul Eggert <eggert@twinsun.com>
9691
9692 * src/getargs.c (version): Update copyright year to 2004.
9693
9694 * data/c.m4 (b4_int_type): Use 'short int' rather than
9695 'short', and similarly for 'long', 'unsigned', etc.
9696 * data/glr.c (YYTRANSLATE, yyconfl, yySymbol, yyItemNum,
9697 yygetLRActions, yyprocessOneStack, yyrecoverSyntaxError,

9747 for GLR parsers.
9748 Use expected_sr_conflicts in place of expected_conflicts.
9749 Warn if expected_rr_conflicts used in non-GLR parser.
9750
9751 * doc/bison.texinfo: Add documentation for %expect-rr.
9752
9753 2004-03-08 Paul Eggert <eggert@gnu.org>
9754
9755 Add support for hex token numbers. Suggested by Odd Arild Olsen in
9756 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
9757
9758 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
9759 in lalr1.cc.
9760 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
9761 * src/scan-gram.l (scan_integer): New function.
9762 ({int}): Use it.
9763 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
9764 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
9765 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
9766 Say "long int", not "long", for uniformity with GNU style.
9767
9768 2004-02-25 Paul Eggert <eggert@twinsun.com>
9769
9770 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
9771 compilers. This fixes a problem with Intel's C++ compiler being
9772 chatty, reported by Guido Trentalancia in
9773 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
9774
9775 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
9776
9777 Support %destructor and merge error locations in lalr1.cc.

9780 (Parser::stos_): Define unconditionally.
9781 (Parser::destruct_): New method. Generate its body with
9782 b4_yydestruct_generate.

9784 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
9785 token which are discarded.
9786 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
9787 error_start_ when erroneous token are discarded.
9788 (Parser::parse) <yyerrlab1>: Compute the location of the error
9789 token so that it covers all the discarded tokens.
9790 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
9791 it can be called with `%skeleton "lalr1.cc"', and do that.
9792
9793 2004-02-02 Paul Eggert <eggert@twinsun.com>
9794
9795 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
9796 $(top_srcdir)/lib and ../lib. This fixes a bug reported
9797 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
9798 There's no need to mention top_builddir since Automake does that
9799 for us.
9800 (INCLUDES): Remove, as Automake says it's obsolescent.
9801 Contents migrated into AM_CPPFLAGS as described above.
9802 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
9803
9804 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9805
9806 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
9807 (yyreportSyntaxError): Handle case where lookahead token is
9808 YYEMPTY.
9809
9810 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
9811
9812 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
9813 resulting parsers are compilable with C++.
9814
9815 2003-12-23 Paul Eggert <eggert@twinsun.com>
9816
9817 * config/depcomp, config/install-sh: Sync with Automake 1.8.
9818 * src/output.c (output_skeleton): Rename local var.
9819 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
9820 Bison tokens, as this runs afoul of the 2003-10-07 change that
9821 disallowed NUL bytes in character constants or string literals.
9822
9823 * tests/local.at: Require Autoconf 2.59's Autotest.
9824 * tests/testsuite.at: Don't include local.at, since we now assume
9825 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
9826 including it.
9827 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
9828 multiple inclusion warnings.
9829
9830 2003-12-02 Akim Demaille <akim@epita.fr>
9831
9832 * doc/bison.texinfo (How Can I Reset the Parser): More about start
9833 conditions.
9834 From Bruno Haible.

9836 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
9837
9838 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
9839
9840 2003-10-07 Paul Eggert <eggert@twinsun.com>
9841
9842 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
9843 if testsuite doesn't exist.
9844
9845 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
9846 literals, unfortunately.
9847 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
9848 Complain about NUL bytes in character constants or string literals.
9849
9850 2003-10-05 Paul Eggert <eggert@twinsun.com>
9851
9852 * NEWS: Don't document %no-default-prec, as it's still
9853 too experimental.
9854 * doc/bison.texinfo: Document %no-default-prec only if
9855 the defaultprec flag is set. Normally it's not.
9856
9857 2003-10-04 Paul Eggert <eggert@twinsun.com>
9858
9859 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
9860 non-modifiable lvalue, instead of a modifiable one.
9861 * doc/bison.texinfo (Actions): Document that $$ can
9862 be assigned to. Do not claim that $$ and $N are
9863 array element references: user code should not rely on this.
9864
9865 2003-10-01 Paul Eggert <eggert@twinsun.com>
9866
9867 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
9868 (grammar_declaration): Use it.
9869 * src/scan-gram.l: New token %no-default-prec.
9870 * tests/conflicts.at: Revamp tests to use %no-default-prec.
9871 * NEWS, doc/bison.texinfo: Document the above.
9872
9873 2003-10-01 Akim Demaille <akim@epita.fr>
9874
9875 VCG no longer supports long_straight_phase.
9876
9877 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
9878 * src/print_graph.c (print_graph): Adjust.
9879
9880 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
9881 and Paul Eggert <eggert@twinsun.com>
9882
9883 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
9884 Table of Symbols): Document %default-prec.

9892 %default-prec with %prec, %default-prec 1): New tests.
9893
9894 2003-09-30 Paul Eggert <eggert@twinsun.com>
9895
9896 * tests/testsuite.at: Include local.at, not input.at, fixing
9897 a typo in the 2003-08-25 patch.
9898
9899 2003-08-27 Akim Demaille <akim@epita.fr>
9900
9901 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
9902 GCC warnings.
9903
9904 2003-08-26 Akim Demaille <akim@epita.fr>
9905
9906 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
9907 "<\#" to avoid magic from Gnus when posting parts of this script.
9908
9909 2003-08-26 Akim Demaille <akim@epita.fr>
9910
9911 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
9912 (Parser::parse): here.
9913 Adjust: nerrs and errstatus is now replaced by...
9914 (Parser::nerrs_, Parser::errstatus_): New.
9915
9916 2003-08-25 Akim Demaille <akim@epita.fr>
9917
9918 * config/announce-gen, Makefile.cfg: New.
9919 * Makefile.am: Adjust.
9920 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
9921 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
9922
9923 2003-08-25 Akim Demaille <akim@epita.fr>
9924
9925 When reducing initial empty rules, Bison parser read an initial
9926 location that is not defined. This results in garbage, and that
9927 affects Bison's own parser. Therefore we need (i) to extend Bison
9928 to support a means to initialize this location, and (ii) to use
9929 this CVS Bison to fix CVS Bison's parser.
9930
9931 * src/reader.h, reader.c (epilogue_augment): Remove, replace
9932 with...
9933 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
9934 * src/parse-gram.y: Adjust.
9935 (%initial-action): New.
9936 (%error-verbose): Since we require CVS Bison, there is no reason
9937 not to use it.
9938 * src/scan-gram.l: Adjust.
9939 * src/Makefile.am (YACC): New, to make sure we use our own parser.
9940 * data/yacc.c (yyparse): Use b4_initial_action.
9941
9942 2003-08-25 Akim Demaille <akim@epita.fr>
9943
9944 * doc/bison.texinfo: Don't promote stdout for error messages.
9945
9946 2003-08-25 Akim Demaille <akim@epita.fr>
9947
9948 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
9949 From Alexandre Duret-Lutz.
9950
9951 2003-08-25 Akim Demaille <akim@epita.fr>

9967 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
9968 error recovery loops. This patch is based on
9969 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
9970 Also, augment the similarity between lalr1.cc and yacc.c.
9971 Note: the locations of error recovery rules are not correct yet.
9972
9973 * data/lalr1.cc: Comment changes to augment the similarity between
9974 lalr1.cc and yacc.c.
9975 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
9976 (yyerrlab1): Remove, but where it used to be (now the bottom part of
9977 yyerrlab), when hitting EOF, pop the whole stack here instead of
9978 merely falling thru the default error handling mechanism.
9979 (yyerrorlab): New label, with the old contents of YYERROR,
9980 plus the following change: pop the stack of rhs corresponding
9981 to the production that invoked YYERROR. That is how Yacc
9982 behaves (required by POSIX).
9983 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
9984 fail.
9985
9986 2003-08-25 Akim Demaille <akim@epita.fr>
9987
9988 Tune local.at so that people can "autom4te -l autotest calc.at -o
9989 calc" for instance, to extract a sub test suite.
9990
9991 * tests/testsuite.at: Move the initialization, Autotest version
9992 requirement, and AT_TESTED invocation into...
9993 * tests/local.at: here.
9994 * tests/testsuite.at: Include it for compatibility with Autoconf
9995 2.57.
9996 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
9997 be ignore.
9998
9999 2003-08-04 Paul Eggert <eggert@twinsun.com>
10000
10001 Rework code slightly to avoid gcc -Wtraditional warnings.
10002 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10003 The returned value is now stored in *YY0. All callers changed.
10004 * src/output.c (merge_output): Adjust to the above change.
10005
10006 2003-07-26 Paul Eggert <eggert@twinsun.com>
10007
10008 * data/glr.c (YYASSERT): New macro.
10009 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10010 yyresolveStates, yyprocessOneStack):
10011 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10012 Derived from a suggestion by Frank Heckenbach.
10013
10014 2003-07-25 Paul Eggert <eggert@twinsun.com>
10015
10016 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10017 for portability to K&R C (after ansi2knr, presumably). See
10018 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10019 by Frank Heckenbach, though I have omitted the structure-initialization
10020 part of his glr-knr.diff patch since I recall that the Portable
10021 C Compiler didn't require that change.
10022
10023 Let the user specify how to allocate and free memory.
10024 Derived from a suggestion by Frank Heckenbach in
10025 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10026 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10027 All uses of free, malloc, realloc changed to use these macros,
10028 and unnecessary casts removed.
10029 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10030
10031 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10032
10033 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10034 use s.empty() rather than s == "" to test for empty string; see
10035 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10036 (trivial change)
10037
10038 2003-06-25 Akim Demaille <akim@epita.fr>
10039
10040 * config/depcomp, config/install-sh: Update from masters.
10041
10042 2003-06-20 Paul Eggert <eggert@twinsun.com>
10043
10044 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10045 and return properly parenthesized result.
10046 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
10047 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10048 Remove unnecessary parentheses from uses.
10049 * doc/bison.texinfo (Location Default Action): Describe the
10050 conventions for parentheses.
10051
10052 2003-06-19 Paul Eggert <eggert@twinsun.com>
10053
10054 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10055 yyreportTree): Do not assume that size_t is the same width as int,
10056 when printing sizes. Print sizes using an unsigned format.
10057 Problem reported by Frank Heckenbach in
10058 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10059
10060 Port to Forte Developer 7 C compiler.
10061 * data/glr.c (struct YYLTYPE): If locations are not being used,
10062 declare a single dummy member, as empty structs do not conform
10063 to the C standard.
10064 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10065 the Forte Developer 7 C compiler complains that end-of-loop
10066 code is not reached.
10067
10068 2003-06-17 Paul Eggert <eggert@twinsun.com>
10069
10070 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
10071 avoid warnings from picky compilers about redefinition of PARAMS.
10072
10073 2003-06-17 Paul Eggert <eggert@twinsun.com>
10074
10075 Version 1.875b.
10076
10077 * NEWS: Document 1.875b.
10078
10079 * lib/bbitset.h: Do not include config.h; that's the includer's job.
10080 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
10081 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10082 Don't use 'index' in comments, as it's a builtin fn on some hosts.
10083 * lib/bitset_stats.c: Include gettext.h unconditionally, as
10084 per recent gettext manual's suggestion.
10085 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
10086 Use prototypes, not old-style definitions.
10087 * lib/lbitset.c (lbitset_unused_clear): Likewise.
10088 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
10089 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
10090 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
10091 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
10092 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
10093 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
10094 vbitset_or_and_cmp, vbitset_copy): Likewise.
10095
10096 * lib/libiberty.h: Do not include config.h; that's the includer's job.
10097 Do not include <stdlib.h>.
10098 (PARAMS): Define unconditionally for C89.
10099 (ATTRIBUTE_NORETURN): Remove.
10100 (ATTRIBUTE_UNUSED): Define unconditionally.
10101
10102 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
10103 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
10104 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
10105 * lib/vbitset.c, lib/vbitset.h: New files.
10106 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
10107 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
10108 from libbitset.
10109
10110 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10111 `How Can I Reset @code{yyparse}', since texinfo does not allow
10112 arbitrary @ in node names.
10113
10114 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10115 shouldn't be needed according to the gettext 0.12.1 documentation
10116 but which seem to be needed anyway: codeset.m4 glibc21.m4
10117 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
10118 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
10119 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
10120
10121 * lib/.cvsignore: Add stdbool.h.
10122 * m4/.cvsignore: Add nls.m4, po.m4.
10123
10124 Upgrade to CVS gnulib.
10125 * stdbool_.h: File renamed from stdbool.h.in.
10126 * configure.ac (AM_STDBOOL_H): Invoke this instead of
10127 AC_HEADER_STDBOOL.
10128 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
10129 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
10130 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
10131 (MOSTLYCLEANFILES): New var.
10132 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
10133 (stdbool.h): New rule.
10134 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
10135 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
10136 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
10137 m4/quote.m4: Upgrade to today's gnulib.
10138
10139 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10140 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10141 the tests right now.
10142 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10143 yyerror are declared before use; C99 requires this.
10144
10145 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10146
10147 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10148 first.
10149 (yyrecoverSyntaxError): Correct the logic for setting and testing
10150 yyerrState.
10151 Correct comment on handling EOF.
10152 Allow states with only a default reduction, rather than failing
10153 (I can't quite reconstruct why these were not allowed before).
10154
10155 Fixes to avoid problem that $-N rules in GLR parsers can cause
10156 buffer overruns, corrupting state.
10157
10158 * src/output.c (prepare_rules): Output max_left_semantic_context
10159 definition.
10160 * src/reader.h (max_left_semantic_context): New variable declaration.
10161 * src/scan-gram.l (max_left_semantic_context): Define.
10162 (handle_action_dollar): Update max_left_semantic_context.
10163 * data/glr.c (YYMAXLEFT): New definition.
10164 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
10165 (yyresolveAction): Ditto.
10166
10167 Fixes to problems with location handling in GLR parsers reported by
10168 Frank Heckenbach (2003/06/05).
10169
10170 * data/glr.c (YYLTYPE): Make trivial if locations not used.
10171 (YYRHSLOC): Add parentheses, and define only if locations used.
10172 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10173 locations not used.
10174 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
10175 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10176
10177 * tests/cxx-type.at: Exercise location information; update tests
10178 to differentiate output with and without locations.
10179 Remove forward declarations of yylex and yyerror---caused errors
10180 because default YYLTYPE not yet defined.
10181 Change semantic actions to compute strings, rather than printing
10182 them directly (to test proper passing of semantics values). Change
10183 output to prefix notation and update test data and expected results.
10184 (yylex): Track locations.
10185 (stmtMerge): Return value rather than printing, and include arguments
10186 in value.
10187
10188 2003-06-03 Paul Eggert <eggert@twinsun.com>
10189
10190 Avoid warnings generated by GCC 2.95.4 when Bison is
10191 configured with --enable-gcc-warnings.
10192 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
10193 yy::]b4_parser_class_name[::translate_,
10194 yy::Stack::operator[] (unsigned),
10195 yy::Stack::operator[] (unsigned) const,
10196 yy::Slice::operator[] (unsigned),
10197 yy::Slice::operator[] (unsigned) const):
10198 Rename local vars to avoid warnings.
10199 * tests/glr-regression.at (Improper handling of embedded actions
10200 and $-N in GLR parsers): Remove unused local variable from yylex.
10201 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
10202 (void) as arg when not pure, since we now assume C89 when building
10203 Bison. Pacify GCC by using parameter.
10204
10205 2003-06-02 Paul Eggert <eggert@twinsun.com>
10206
10207 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
10208 yy::Location::lines, yy::Location::columns): Rename arguments
10209 to avoid shadowing; this removes a warning generated by GCC 3.3.
10210
10211 2003-06-01 Paul Eggert <eggert@twinsun.com>
10212
10213 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10214 to g++, as GCC 3.3 complains if you do it.
10215 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10216 everything that WARNING_CFLAGS has, except omit warnings
10217 not suitable for C++.
10218 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
10219 * tests/atlocal.in (CXXFLAGS): New var.
10220 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10221
10222 Fix a GLR parser bug I reported in February; see
10223 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10224 The problem was that GLR parsers did not conform to the C standard,
10225 because actions like { $1 = $2 + $3; } expanded to expressions
10226 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10227 to a local variable. The C standard says that expressions
10228 like (var = f ()) + (var = f ()) have undefined behavior.
10229 Another problem was that GCC sometimes issues warnings that
10230 yyfill and its parameters are unused.
10231
10232 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10233 as possibly unused.
10234 (yyfill): New function.
10235 (YYFILL): Use it.
10236 (yyuserAction): Change type of yynormal to bool, so that it matches
10237 the new yyfill signature. Mark it as possibly unused.
10238
10239
10240 Follow up on a bug I reported in February, where a Bison-generated
10241 parser can loop. Provide a test case and a fix for yacc.c. I
10242 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10243 The original bug report is in:
10244 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10245
10246 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10247 macro's size was becoming unwieldy.
10248 (yyerrlab): Do not discard an empty lookahead symbol, as this
10249 might destroy garbage.
10250 (yyerrorlab): New label, with the old contents of YYERROR,
10251 plus the following change: pop the stack of rhs corresponding
10252 to the production that invoked YYERROR. That is how Yacc
10253 behaves, and POSIX requires this behavior.
10254 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10255 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10256 Define 'alarm' to do nothing if unistd.h is not available.
10257 Add a new rule "exp: '-' error;" to test the above change to
10258 data/yacc.c. Use 'alarm' to abort any test taking longer than
10259 10 seconds, as it's probably looping.
10260 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10261 Also, the new yacc.c generates two fewer diagnostics for an
10262 existing test.
10263
10264 2003-05-24 Paul Eggert <eggert@twinsun.com>
10265
10266 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10267 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10268 This fixes a problem reported by John Bowman when the Compaq/HP
10269 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10270 -ansi -Wall -gall).
10271 * data/yacc.c (union yyalloc): Likewise.
10272 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10273
10274 Switch from 'int' to 'bool' where that makes sense.

10279 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10280 Return or accept bool, not int. All callers changed.

10282 bitset_andn_or_cmp_, bitset_or_and_cmp_): Likewise.
10283 * lib/bitset.c (bitset_only_set_p, bitset_print, bitset_toggle_,

10290 bitset_stats_andn_cmp, bitset_stats_or_cmp, bitset_stats_xor_cmp,
10291 bitset_stats_and_or_cmp, bitset_stats_andn_or_cmp,
10292 bitset_stats_or_and_cmp): Likewise.
10293 * lib/ebitset.c (ebitset_elt_zero_p, ebitset_equal_p, ebitset_copy_cmp,
10294 ebitset_test, ebitset_empty_p, ebitset_subset_p, ebitset_disjoint_p,
10295 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
10296 ebitset_xor_cmp): Likewise.
10297 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
10298 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
10299 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10300 lbitset_xor_cmp): Likewise.
10301 * lib/bbitset.h: Include <stdbool.h>.
10302 (struct bitset_vtable): The following members now return bool, not
10303 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10304 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10305 or_and_cmp).
10306 * src/conflicts.c (count_rr_conflicts): Likewise.
10307 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10308 All uses changed.
10309 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10310 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10311 * src/getargs.c (debug_flag, defines_flag, locations_flag,

10322 (long_options, getargs): Use it.
10323 * src/lalr.c (build_relations): Use bool, not int.
10324 * src/nullable.c (nullable_compute): Likewise.
10325 * src/print.c (print_reductions): Likewise.

10339 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10340 semicolon after a grammar declaration, in the interest of possible
10341 future changes to the Bison input language.
10342 Do not allow a stray semicolon at the start of the grammar.
10343 (rhses.1): Allow one or more semicolons after any rule, including
10344 just before "|" as required by POSIX.
10345 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10346 grammar.
10347
10348 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10349
10350 %parse-param support for lalr1.cc.
10351
10352 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10353 b4_cc_constructor_calls, b4_cc_constructor_call,
10354 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10355 definitions.
10356 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10357 parse-param arguments.
10358 (yy::b4_parser_class_name): Declare instance variables to
10359 hold parse-param arguments.
10360 * tests/calc.at: s/value/semantic_value/ because value clashes
10361 with a member of yy::b4_parser_class_name. Adjust C++ code
10362 to handle %parse-param. Enable %parse-param test in C++.
10363
10364 2003-05-12 Paul Eggert <eggert@twinsun.com>
10365
10366 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10367 English a bit. Fix fclose typo. Change "const char" to "char
10368 const", and use ANSI C rather than K&R for "main". Suggest
10369 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10370 and suggest yy_switch_to_buffer.
10371
10372 2003-05-05 Paul Eggert <eggert@twinsun.com>
10373
10374 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10375 C89. This avoids a diagnostic on compilers that define __STDC__
10376 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10377 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10378
10379 2003-05-03 Paul Eggert <eggert@twinsun.com>
10380
10381 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10382 Do not overrun array bounds.
10383 This should fix a bug reported today by Olatunji Oluwabukunmi in
10384 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10385
10386 2003-04-29 Akim Demaille <akim@epita.fr>
10387
10388 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10389 * src/getargs.c, src/getargs.h: here, as bool, not int.
10390 (nondeterministic_parser): New.
10391 * src/parse-gram.y, src/scan-gram.l: Support
10392 %nondeterministic-parser.
10393 * src/output.c (prepare): Use nondeterministic_parser instead
10394 of glr_parser where appropriate.
10395 * src/tables.c (conflict_row, action_row, save_row)
10396 (token_actions, token_actions, pack_vector): Ditto.
10397
10398 2003-04-29 Akim Demaille <akim@epita.fr>
10399
10400 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10401
10402 2003-04-29 Akim Demaille <akim@epita.fr>
10403
10404 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10405 with %pure-parser and %locations to exercise the patch from Yakov
10406 Markovitch below.
10407
10408 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10409
10410 * data/yacc.c: (b4_lex_param): Corrected for the case where
10411 %lex-param is provided and %pure-parser isn't.
10412
10413 2003-04-27 Paul Eggert <eggert@twinsun.com>
10414
10415 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10416 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10417 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10418 if it is not defined.
10419 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10420
10421 2003-04-26 Paul Eggert <eggert@twinsun.com>
10422
10423 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10424 Declare to be of type suitable for the ninf value itself, not of
10425 type suitable for the corresponding table, since the latter might
10426 be unsigned but the ninf value might be negative. This fixes a
10427 bug reported by Alexandre Duret-Lutz in
10428 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10429
10430 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10431 invokes it. We shouldn't invoke it twice because it will attempt
10432 to put error.o in the archive twice. This fixes a glitch reported
10433 by Martin Mokrejs in
10434 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10435
10436 2003-04-21 Paul Eggert <eggert@twinsun.com>
10437
10438 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10439 to gnulib.
10440
10441 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10442
10443 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10444 Fix obvious typo that results in uncompilable GLR parsers
10445 when both %pure-parser and %locations are used. (trivial change)
10446
10447 2003-04-17 Paul Eggert <eggert@twinsun.com>
10448
10449 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10450 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10451 Do not insert the expected token via unput, as this runs afoul
10452 of a POSIX-compatibility bug in flex 2.5.31.
10453 All uses changed to BEGIN the parent state,
10454 since we no longer insert the expected token via unput.
10455 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10456 that is no longer emitted after the above change.
10457
10458 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10459 the first one. This change is from Paul Hilfinger, and it fixes
10460 regression reported by Werner Lemberg in
10461 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10462
10463 (resolve_sr_conflict): Don't invoke state_errs_set
10464 unless one or more tokens have been explicitly made errors.
10465 Otherwise, the above change causes Bison to abort.
10466
10467 * tests/existing.at (GNU pic Grammar): New test case, taken from
10468 Lemberg's email.
10469
10470 2003-03-31 Akim Demaille <akim@epita.fr>
10471
10472 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10473
10474 2003-03-31 Akim Demaille <akim@epita.fr>
10475
10476 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10477 output.
10478
10479 2003-03-31 Akim Demaille <akim@epita.fr>
10480
10481 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10482 From Paul Hilfinger.
10483
10484 2003-03-29 Akim Demaille <akim@epita.fr>
10485
10486 * m4/error.m4: Do not put under dynamic conditions some code which
10487 expansion is under static control.
10488
10489 2003-03-29 Akim Demaille <akim@epita.fr>
10490
10491 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10492
10493 2003-03-29 Akim Demaille <akim@epita.fr>
10494
10495 * doc/bison.texinfo (Strings are Destroyed): New.
10496
10497 2003-03-13 Paul Eggert <eggert@twinsun.com>
10498
10499 * .cvsignore: Add configure.lineno.
10500 * src/.cvsignore: Add yacc.
10501 * tests/.cvsignore: Add testsuite.log.
10502 * doc/fdl.texi: Sync with latest FSF version.
10503
10504 2003-03-12 Paul Eggert <eggert@twinsun.com>
10505
10506 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10507 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10508 cursor, instead of leaving it undefined. This fixes a bug
10509 reported by Tim Van Holder in
10510 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10511 * tests/input.at (Torturing the Scanner): Test the scanner on
10512 an empty input file, which was Tim Van Holder's test case.
10513
10514 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10515 <sys/resource.h> can be included, include sys/time.h and
10516 sys/times.h first, if available. This works around the SunOS
10517 4.1.4 porting bug reported by Bruce Becker in
10518 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10519
10520 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10521 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10522 AC_HEADER_SYS_WAIT.
10523
10524 Merge changes from gnulib. This was prompted because the CVS
10525 snapshot didn't build on Solaris 7 due to strnlen problems.
10526
10527 These changes need to be merged back into gnulib:
10528 * lib/hash.c: Include <stdbool.h> unconditionally.
10529 * m4/onceonly.m4 (m4_quote): New macro.
10530 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10531 Quote AC_FOREACH variable-expansions properly.
10532 The 2003-01-03 obstack.h change also needs merging.
10533 {end of changes requiring merging}
10534
10535 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10536 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10537 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10538 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10539 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10540 New files, imported from gnulib.
10541 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10542 above.
10543
10544 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10545 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10546 gnulib sources.
10547
10548 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10549 Add.
10550 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10551 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10552 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10553 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10554 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10555 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10556 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10557 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10558 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10559 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10560 (jm_PREREQ_ARGMATCH): Remove.
10561 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10562 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10563
10564 * src/system.h: Include <stdbool.h> unconditionally.
10565
10566 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10567 assuming at least C89 in the bitset code for some time now.
10568
10569 2003-03-03 Akim Demaille <akim@epita.fr>
10570
10571 * ro.po: New.
10572
10573 2003-03-02 Akim Demaille <akim@epita.fr>
10574
10575 * doc/bison.texinfo (Table of Symbols): Reactivate the
10576 documentation for %lex-param, and %parse-param.
10577
10578 2003-03-02 Akim Demaille <akim@epita.fr>
10579
10580 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10581 generate verbose error messages.
10582 Use the number of tokens as an upper bound in yytname, as it
10583 cannot be a non terminal.
10584
10585 2003-03-02 Akim Demaille <akim@epita.fr>
10586
10587 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10588 message.
10589
10590 2003-03-02 Akim Demaille <akim@epita.fr>
10591
10592 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10593 Use them to exercise yycheck overrun.
10594 Based on Andrew Suffield's grammar.
10595
10596 2003-03-02 Akim Demaille <akim@epita.fr>
10597
10598 Create tests/local.at for Bison generic testing macros.
10599
10600 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10601 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10602 This new file.
10603 * tests/calc.at (AT_CHECK_CALC): Adjust.
10604 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10605 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10606 * tests/local.at: here.
10607 (AT_COMPILE_CXX): Tags the tests using it as c++.
10608 Ignore the test if CXX is not functional.
10609
10610 2003-03-01 Paul Eggert <eggert@twinsun.com>
10611
10612 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10613 not loc->end, since loc->end might contain garbage and this leads
10614 to undefined behavior on some platforms.
10615 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10616 depend on *loc, so that the reader doesn't give the the false
10617 impression that *loc is initialized.
10618 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10619 does not survive the return.
10620
10621 2003-03-01 Akim Demaille <akim@epita.fr>
10622
10623 * src/scan-gram.l (code_start): Always initialize it when entering
10624 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10625 yylex invocation. An alternative would be making it static, but
10626 then it starts with the second %%'s beginning, instead of its end.
10627
10628 2003-02-28 Paul Eggert <eggert@twinsun.com>
10629
10630 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10631 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10632 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10633
10634 2003-02-26 Paul Eggert <eggert@twinsun.com>
10635
10636 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10637 Remove Sequent/Pyramid discussion (nobody uses them any more).
10638 Merge VMS and MS-DOS discussion; these ports may well be dead
10639 but let's keep mentioning them for now. Put <> around email
10640 addresses. Add copyright notice.
10641
10642 2003-02-24 Paul Eggert <eggert@twinsun.com>
10643
10644 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10645 to avoid collision with flex use of yylineno.
10646 Problem reported by Bruce Lilly in
10647 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
10648 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
10649 * data/yacc.c (yy_reduce_print): Likewise.
10650
10651 * config/depcomp: Sync with Automake 1.7.3.
10652
10653 2003-02-21 Akim Demaille <akim@epita.fr>
10654
10655 * data/lalr1.cc: Use temporary variables instead of casts to
10656 change integer types.
10657 Suggested by Paul Eggert.
10658
10659 2003-02-21 Akim Demaille <akim@epita.fr>
10660
10661 * doc/bison.texinfo: Use "location" consistently to refer to @n,
10662 to avoid confusions with lalr1.cc's notion of Position.
10663 Suggested by Paul Eggert.
10664
10665 2003-02-20 Akim Demaille <akim@epita.fr>
10666
10667 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
10668 before initial_columns.
10669 (location.hh): Use consistent variable names when defining the
10670 operator<<.
10671 Use "last" so that we subtract from Positions, not from unsigned.
10672
10673 2003-02-20 Akim Demaille <akim@epita.fr>
10674
10675 * data/lalr1.cc (position.hh): New subfile, including the extended
10676 and Doxygen'ed documentation of class Position.
10677 (location.hh): Use it.
10678 Document a` la Doxygen.
10679 With the help of Benoit Perrot.
10680
10681 2003-02-20 Akim Demaille <akim@epita.fr>
10682
10683 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
10684 AT_YACC_IF.
10685 Redefine AT_YYERROR_SEES_LOC_IF using it.
10686 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
10687 not defined.
10688 Don't use the location in yy::Parser::error_ and
10689 yy::Parser::print_ when not %locations.
10690 Activate more lalr1.cc tests.
10691
10692 2003-02-19 Akim Demaille <akim@epita.fr>
10693
10694 * data/lalr1.cc: When displaying a line number, be sure to make it
10695 an int.
10696
10697 2003-02-19 Akim Demaille <akim@epita.fr>
10698
10699 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
10700 Remove, useless.
10701 (YYABORT, YYACCEPT, YYERROR): New.
10702 * tests/calc.at: Renable the lalr1.cc test.
10703
10704 2003-02-19 Akim Demaille <akim@epita.fr>
10705
10706 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
10707 error recovery, mixing with/without pops and discarding of the
10708 lookahead.
10709 Exercise YYERROR.
10710 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
10711
10712 2003-02-17 Paul Eggert <eggert@twinsun.com>
10713
10714 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
10715 * tests/testsuite.at (AT_COMPILE): Use them.
10716 This fixes the testsuite problem reported by Robert Lentz in
10717 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
10718
10719 2003-02-12 Paul Eggert <eggert@twinsun.com>
10720
10721 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
10722 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
10723 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
10724 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
10725 Check for malloc failure, for consistency with yacc.c.
10726 (yytname_size): Remove, for consistency with yacc.c.
10727
10728 The bug still remains in data/lalr1.cc, as I didn't have time
10729 to fix it there.
10730
10731 2003-02-06 Akim Demaille <akim@epita.fr>
10732
10733 * configure.ac (GXX): Rename as...
10734 (CXX): this, to keep the original Autoconf semantics.
10735 Require 2.57.
10736 * data/lalr1.cc: Fix b4_copyright invocations.
10737 If YYDEBUG is not defined, don't depend upon name_ being defined.
10738 (location.hh): Include string and iostream.
10739 (Position::filename): New member.
10740 (Position::Position ()): New.
10741 (operator<< (Position)): New.
10742 (operator- (Position, int)): New.
10743 (Location::first, Location::last): Rename as...
10744 (Location::begin, Location::end): these, to mock the conventional
10745 iterator names.
10746 (operator<< (Location)): New.
10747 * tests/atlocal.in (CXX): New.
10748 * tests/testsuite.at (AT_COMPILE_CXX): New.
10749 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
10750 locations in a more synthetic way.
10751 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
10752 lalr1.cc is used.
10753 Adjust the C locations to match those from Emacs: first column is
10754 column 0.
10755 Change all the expected results.
10756 Conform to the GCS: simplify the locations when applicable.
10757 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
10758 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
10759 these CPP macros with the m4 macros new defined by...
10760 (AT_CHECK_PUSHDEFS): this, i.e.:
10761 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
10762 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
10763 New macros.
10764 (AT_CHECK_POPDEFS): Undefine them.
10765 (AT_CHECK_CALC_LALR1_CC): New.
10766 Use it for the first lalr1.cc test.
10767
10768 2003-02-04 Akim Demaille <akim@epita.fr>
10769
10770 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
10771 Location as is defined.
10772
10773 2003-02-04 Akim Demaille <akim@epita.fr>
10774
10775 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
10776 name_ being defined.
10777
10778 2003-02-03 Paul Eggert <eggert@twinsun.com>
10779
10780 * src/gram.h (start_symbol): Remove unused decl.
10781
10782 Use more-consistent naming conventions for local vars.
10783
10784 * src/derives.c (derives_compute): Change type of local var from
10785 int to rule_number.
10786 * src/gram.c (grammar_rules_partial_print): Likewise.
10787 * src/print.c (print_core): Likewise.
10788 * src/reduce.c (reduce_grammar_tables): Likewise.
10789
10790 * src/gram.c (grammar_dump): Change name of item_number *
10791 local var from r to rp.
10792 * src/nullable.c (nullable_compute): Likewise.
10793
10794 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
10795
10796 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
10797 for symbol or symbol_number var.
10798 * src/reader.c (grammar_start_symbol_set): Likewise.
10799 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
10800 Likewise.
10801 * src/state.c (transitions_to): Likewise.
10802 * src/state.h: Likewise.
10803 * src/tables.c (symbol_number_to_vector_number): Likewise.
10804
10805 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
10806 char * var.
10807
10808 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
10809 var.
10810
10811 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
10812 var.
10813
10814 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
10815 Use str, not s, for char * var. Use ch, not c, for character var.
10816 Use size for size var.
10817
10818 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
10819 char * var.
10820 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
10821 uniqstr var.
10822 * src/uniqstr.h: Likewise.
10823
10824 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
10825 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
10826 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
10827 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
10828 param to have same name as that of enum, so that we don't use
10829 "s" to stand for a non-state.
10830
10831 2003-02-02 Akim Demaille <akim@epita.fr>
10832
10833 * src/scan-skel.l: Scan more than one inert character per yylex
10834 invocation.
10835
10836 2003-02-01 Paul Eggert <eggert@twinsun.com>
10837
10838 Version 1.875a.
10839
10840 * po/LINGUAS: Add ms.
10841
10842 2003-01-30 Akim Demaille <akim@epita.fr>
10843
10844 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
10845
10846 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10847
10848 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
10849 of $1.
10850
10851 Changes in response to error report by S. Eken: GLR mode does not
10852 handle negative $ indices or $ indices in embedded rules correctly.
10853 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
10854
10855 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
10856 (b4_rhs_location): Ditto.
10857 (yyfill): New function to copy from stack tree into array
10858 incrementally.
10859 (yyuserAction): Modify to allow incremental move of semantic values
10860 to rhs array when in GLR mode.
10861 Define YYFILL to use in user-defined actions to fill semantic array
10862 as needed.
10863 Remove dummy use of yystack, as there is now a guaranteed use.
10864 (yydoAction): Modify to allow incremental move of semantic values
10865 to rhs array when in GLR mode.
10866 (yyresolveAction): Ditto.
10867 (yyglrShiftDefer): Update comment.
10868 (yyresolveStates): Use X == NULL for pointers, not !X.
10869 (yyglrReduce): Ditto.
10870 (yydoAction): Ditto
10871
10872 * tests/glr-regr1.at: Rename to ...
10873 * tests/glr-regression.at: Add new regression test for the problems
10874 described above (adapted from S. Eken).
10875 Update copyright notice.
10876 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
10877 * tests/Makefile.am: Ditto.
10878
10879 2003-01-28 Paul Eggert <eggert@twinsun.com>
10880
10881 * data/lalr1.cc: Do not use @output_header_name@ unless
10882 b4_defines_flag is set. This fixes two bugs reported by
10883 Tim Van Holder in
10884 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
10885 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
10886
10887 2003-01-21 Paul Eggert <eggert@twinsun.com>
10888
10889 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
10890 we don't need to worry about yyerrlab1 being reported as an
10891 "unused label" by non-GCC C compilers. The downside is that if
10892 locations are used then a couple of statements are duplicated each
10893 time YYERROR is invoked, but the upside is that the warnings
10894 should vanish.
10895 (yyerrlab1): Move code to YERROR.
10896 (yyerrlab2): Remove. Change uses back to yyerrlab1.
10897 This reverts some of the 2002-12-27 change.
10898
10899 2003-01-17 Paul Eggert <eggert@twinsun.com>
10900
10901 * src/output.c (symbol_printers_output): Fix typo that led
10902 to core dump. Problem reported by Antonio Rus in
10903 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
10904
10905 2003-01-13 Akim Demaille <akim@epita.fr>,
10906 Quoc Peyrot <chojin@lrde.epita.fr>,
10907 Robert Anisko <anisko_r@lrde.epita.fr>
10908
10909 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
10910 when the stacks contain one element, as the loop would otherwise
10911 free the last state, and then use the top state (the one we just
10912 popped). This means that the initial elements will not be freed
10913 explicitly, as is the case in yacc.c; it is not a problem, as
10914 these elements have fake values.
10915
10916 2003-01-11 Paul Eggert <eggert@twinsun.com>
10917
10918 * NEWS: %expect-violations are now just warnings, reverting
10919 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
10920 bootstrapping problem reported by Matthias Klose; see
10921 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
10922 * src/conflicts.c (conflicts_print): Likewise.
10923 * tests/conflicts.at (%expect not enough, %expect too much,
10924 %expect with reduce conflicts): Likewise.
10925 * doc/bison.texinfo (Expect Decl): Document this. Also mention
10926 that the warning is enabled if the number of conflicts changes
10927 (not necessarily increases).
10928
10929 * src/getargs.c (version): Update copyright year.
10930
10931 2003-01-09 Akim Demaille <akim@epita.fr>
10932
10933 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
10934
10935 2003-01-08 Paul Eggert <eggert@twinsun.com>
10936
10937 * Makefile.maint (WGETFLAGS):
10938 New macro, containing "-C off" to disable proxy caches.
10939 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
10940 (rel-check): Use $(WGET) instead of wget.
10941
10942 2003-01-06 Paul Eggert <eggert@twinsun.com>
10943
10944 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
10945 the GLR paper of Scott, Johnstone and Hussain.
10946
10947 2003-01-04 Paul Eggert <eggert@twinsun.com>
10948
10949 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
10950 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
10951 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
10952 (EXTRA_LIBRARIES): New var, for liby.a.
10953 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
10954 (EXTRA_SCRIPTS): New var, for yacc.
10955
10956 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
10957 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
10958 Problem reported by Nelson H. F. Beebe.
10959
10960 2003-01-03 Paul Eggert <eggert@twinsun.com>
10961
10962 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
10963 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
10964 when compiling Bison 1.875's `bitset bset = obstack_alloc
10965 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
10966
10967 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
10968 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
10969 grow to a huge size with typical invocation.
10970
10971 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
10972 Use the pattern recommended by Autoconf 2.57, except also protect
10973 against double-definition.
10974 * src/system.h: Likewise.
10975 Portability issues reported by Nelson H. F. Beebe.
10976
10977 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
10978 All uses changed. Provide a definition in both C and C++.
10979 (yytrue, yyfalse): Define even if defined (__cplusplus).
10980
10981 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
10982 Reported by Nelson H. F. Beebe.
10983
10984 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
10985
10986 2003-01-02 Paul Eggert <eggert@twinsun.com>
10987
10988 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
10989 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
10990 Bug reported by Nelson H. F. Beebe.
10991
10992 2003-01-01 Paul Eggert <eggert@twinsun.com>
10993
10994 * Version 1.875.
10995
10996 2002-12-30 Paul Eggert <eggert@twinsun.com>
10997
10998 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
10999 Moved here from...
11000 (<INITIAL>","): Here. This causes stray "," to be treated
11001 more uniformly.
11002
11003 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11004 last brace in braced code when not in Yacc mode, for compatibility
11005 with Bison 1.35. This resurrects the 2001-12-15 patch to
11006 src/reader.c.
11007
11008 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11009 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11010
11011 2002-12-28 Paul Eggert <eggert@twinsun.com>
11012
11013 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11014 that of SYM's type. This fixes Debian bug 168069, reported by
11015 Thomas Olsson.
11016
11017 2002-12-28 Paul Eggert <eggert@twinsun.com>
11018
11019 Version 1.75f.
11020
11021 Switch back to the Yacc style of conflict reports, undoing some
11022 of the 2002-07-30 change.
11023 * doc/bison.texinfo (Understanding): Use Yacc style for
11024 conflict reports. Also, use new way of locating rules.
11025 * src/conflicts.c (conflict_report):
11026 Renamed from conflict_report_yacc, removing the old
11027 'conflict_report'. Translate the entire conflict report at once,
11028 so that we don't assume that "," has the same interpretation in
11029 all languages.
11030 (conflicts_output): Use Yacc-style conflict report for each state,
11031 instead of our more-complicated style.
11032 (conflicts_print): Use Yacc-style conflict report, except print
11033 the input file name when not emulating Yacc.
11034 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11035 Conflicted Reduction, %expect not enough, %expect too much,
11036 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11037 * tests/existing.at (GNU Cim Grammar): Likewise.
11038 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11039
11040 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11041 fatal): Don't invoke fflush; it's not needed and it might even be
11042 harmful for stdout, as stdout might not be open.
11043 * src/reduce.c (reduce_print): Likewise.
11044
11045 2002-12-27 Paul Eggert <eggert@twinsun.com>
11046
11047 Fix a bug where error locations were not being recorded correctly.
11048 This problem was originally reported by Paul Hilfinger in
11049 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11050
11051 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11052 top of the location stack's error locations.
11053 (yyerrlab): Set it. When discarding a token, push its location
11054 onto yylerrsp so that we don't lose track of the error's end.
11055 (yyerrlab1): Now is only the target of YYERROR, so that we can
11056 properly record the location of the action that failed. For GCC
11057 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11058 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11059 (yyerrlab2): New label, which yyerrlab now falls through to.
11060 Compute the error's location by applying YYLLOC_DEFAULT to
11061 the locations of all the symbols that went into the error.
11062 * doc/bison.texinfo (Location Default Action): Mention that
11063 YYLLOC_DEFAULT is also invoked for syntax errors.
11064 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11065 Error locations include the locations of all the tokens that were
11066 discarded, not just the last token.
11067
11068 2002-12-26 Paul Eggert <eggert@twinsun.com>
11069
11070 * src/files.c: Include quote.h.
11071 (compute_output_file_names): Warn if we detect conflicting
11072 outputs to the same file. This should catch the misunderstanding
11073 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11074
11075 * src/conflicts.c (conflicts_print): If the user specifies
11076 "%expect N", report an error if there are any reduce/reduce
11077 conflicts. This is what the manual says should happen.
11078 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11079 * tests/conflicts.at (%expect with reduce conflicts): New test.
11080
11081 Don't use m4_include on relative file names, as it doesn't work as
11082 desired if there happens to be a file with that name under ".".
11083
11084 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11085 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11086 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11087 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11088 * src/output.c (output_skeleton): Use full path names when
11089 specifying a file to include; don't rely on include path, as
11090 it's unreliable when the working file contains a file with
11091 that name.
11092
11093 2002-12-25 Paul Eggert <eggert@twinsun.com>
11094
11095 Remove obsolete references to bison.simple and bison.hairy.
11096 Problem mentioned by Aubin Mahe in
11097 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11098 * data/glr.c: Comment fix.
11099 * doc/bison.1: Remove references. Also, mention "yacc".
11100
11101 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11102 with -g option.
11103
11104 * src/parse-gram.y (declaration): Use enum "report_states" rather
11105 than its numeric value 1.
11106
11107 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11108 opening a new one. This fixes Debian bug 165349, reported by
11109 Bruce Stephens.
11110
11111 2002-12-24 Paul Eggert <eggert@twinsun.com>
11112
11113 Version 1.75e.
11114
11115 * Makefile.maint (cvs-update): Don't assume that the shell
11116 supports $(...), as Solaris sh doesn't.
11117
11118 * src/parse-gram.y (lloc_default): Remove test for empty
11119 nonterminals at the end, since it didn't change the result.
11120
11121 2002-12-24 Paul Eggert <eggert@twinsun.com>
11122
11123 If the user does not define YYSTYPE as a macro, Bison now declares it
11124 using typedef instead of defining it as a macro. POSIX requires this.
11125 For consistency, YYLTYPE is also declared instead of defined.
11126
11127 %union directives can now have a tag before the `{', e.g., the
11128 directive `%union foo {...}' now generates the C code
11129 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11130 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11131 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11132 instead of `yyltype'.
11133
11134 `yystype' and `yyltype' are now obsolescent macros instead of being
11135 typedefs or tags; they are no longer documented and will be
11136 withdrawn in a future release.
11137
11138 * data/glr.c (b4_location_type): Remove.
11139 (YYSTYPE): Renamed from yystype.
11140 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11141 (struct YYLTYPE): Renamed from struct yyltype.
11142 (YYLTYPE): Renamed from yyltype.
11143 (yyltype, yystype): New (and obsolescent) macros,
11144 for backward compatibility.
11145 * data/yacc.c: Likewise.
11146
11147 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11148 does not specify a union tag. This is for compatibility with
11149 Solaris 9 yacc.
11150
11151 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11152 const *, since it is now modified by stripping surrounding { }.
11153 (current_braced_code): Remove.
11154 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11155 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11156 trailing " {...}". Now of type <chars>.
11157 (grammar_declaration): Adjust to bundled tokens.
11158 (code_content): Remove; stripping is now done by add_param.
11159 (print_token_value): Print contents of bundled tokens.
11160 (token_name): New function.
11161
11162 * src/reader.h (braced_code, current_braced_code): Remove.
11163 (token_name): New decl.
11164
11165 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11166 token_type, not braced_code code_kind. All uses changed.
11167 (SC_PRE_CODE): New state, for scanning after a keyword that
11168 has (or usually has) an immediately-following braced code.
11169 (token_type): New local var, to keep track of which token type
11170 to return when scanning braced code.
11171 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11172 <INITIAL>"%parse-param", <INITIAL>"%printer",
11173 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11174 instead of returning a token type immediately.
11175 (<INITIAL>"{"): Set token type.
11176 (<SC_BRACED_CODE>"}"): Use it.
11177 (handle_action_dollar, handle_action_at): Now returns bool
11178 indicating success. Fail if ! current_rule; this prevents a core dump.
11179 (handle_symbol_code_dollar, handle_symbol_code_at):
11180 Remove; merge body into caller.
11181 (handle_dollar, handle_at): Complain in invalid contexts.
11182
11183 * NEWS, doc/bison.texinfo: Document the above.
11184 * NEWS: Fix years and program names in copyright notice.
11185
11186 2002-12-17 Paul Eggert <eggert@twinsun.com>
11187
11188 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11189 Reporting, Table of Symbols): Omit mentions of %lex-param and
11190 %parse-param from the documentation for now.
11191
11192 2002-12-15 Paul Eggert <eggert@twinsun.com>
11193
11194 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11195 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11196 lookahead symbol, and which sets yychar in parser actions) and it
11197 disagreed with the Bison documentation. Bug
11198 reported by Andrew Walrond.
11199
11200 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
11201 as the caller now does that.
11202 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
11203 (YYEMPTY): Parenthesize right hand side, since others use it.
11204 (yyparse): Don't assume that our generated code is the only code
11205 that sets yychar.
11206
11207 2002-12-13 Paul Eggert <eggert@twinsun.com>
11208
11209 Version 1.75d.

11236 locations are requested.
11237
11238 2002-12-12 Paul Eggert <eggert@twinsun.com>
11239
11240 Remove unportable casts and storage allocation tricks.
11241 While we're at it, remove almost all casts, since they
11242 usually aren't needed and are a sign of trouble.
11243
11244 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11245
11246 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11247 the pointer DSET returned by malloc; this isn't portable.
11248 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11249 Similarly for DERIVES.
11250 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11251 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11252 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11253
11254 * src/derives.c (derives_compute): Do not bother invoking
11255 int_of_rule_number, since rule numbers are integers.
11256
11257 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11258 rather than XMALLOC (char, N).

11261
11262 * src/gram.h (symbol_number_as_item_number,
11263 item_number_as_symbol_number, rule_number_as_item_number,
11264 item_number_as_rule_number):
11265 Now inline functions rather than macros, to avoid casts.
11266 * src/state.h (state_number_as_int): Likewise.
11267 * src/tables.c (state_number_to_vector_number,
11268 symbol_number_to_vector_number): Likewise.

11270 * src/gram.h (int_of_rule_number): Remove; no longer used.
11271
11272 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11273 since the resulting storage is always stored into.
11274
11275 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11276 where it's needed.
11277
11278 * src/muscle_tab.c (muscle_m4_output):
11279 Now inline. Return bool, not int.
11280 * src/state.c (state_compare): Likewise.

11284 Likewise.
11285 * src/uniqstr.c (uniqstr_print): Likewise.
11286 * src/muscle_tab.c (muscle_m4_output_processor):
11287 New function, to avoid casts.
11288 * src/state.c (state_comparator, stage_hasher): Likewise.
11289 * src/symtab.c (symbol_check_defined_processor,
11290 symbol_check_alias_consistency_processor, symbol_pack_processor,
11291 symbol_translation_processor, hash_symbol_comparator,
11292 hash_symbol_hasher): Likewise.
11293 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11294 * src/muscle_tab.c (muscles_m4_output):
11295 Use new functions instead of casting old functions unportably.
11296 * src/state.c (state_hash_new): Likewise.

11298 symbols_token_translations_init):
11299 Likewise.
11300 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11301
11302 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11303 var instead of casting to long, to avoid casts.
11304 (prepare_states): Use MALLOC rather than alloca, so that we don't
11305 have to worry about alloca.
11306 * src/state.c (state_hash_lookup): Likewise.
11307
11308 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11309 local var instead of casting to unsigned char, to avoid casts.
11310
11311 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11312 STATE_ALLOC): Remove.
11313 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11314 rather than calloc, and use offsetof to avoid allocating slightly
11315 too much storage.
11316 (state_new): Initialize all members.
11317
11318 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11319
11320 * src/symtab.c (symbol_free): Remove; unused.
11321 (symbol_get): Remove cast in lhs of assignment.
11322 (symbols_do): Now static. Accept generic arguments, not
11323 hashing-related ones.
11324
11325 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11326 (symbol_processor): Remove.
11327 (symbols_do): Remove decl; now static.

11330 (<stddef.h>): Include, for offsetof.
11331 (<inttypes.>, <stdint.h>): Include if available.
11332 (uintptr_t): New type, if system lacks it.
11333 (CALLOC, MALLOC, REALLOC): New macros.
11334 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11335 new macros.

11340 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
11341 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
11342
11343 * src/vcg.h: Correct misspellings.
11344
11345 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
11346
11347
11348 * src/getargs.c (getargs): Don't assume EOF == -1.
11349
11350 2002-12-09 Paul Eggert <eggert@twinsun.com>
11351
11352 Change identifier spellings to avoid collisions with names
11353 that are reserved by POSIX.
11354
11355 Don't use names ending in _t, since POSIX reserves them.
11356 For consistency, remove _e and _s endings -- they're weren't
11357 needed to remove ambiguity. All uses changed.
11358 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11359 turn was just renamed from struniq_t.
11360 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11361 which in turn was just renamed from struniq_processor_t.
11362 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which

11433 value_t_as_yystype -> value_as_yystype.
11434
11435 Don't include <errno.h> in the mainstream code, since it
11436 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11437 * lib/get-errno.c, lib/get-errno.h: New files.
11438 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11448 (TAB_EXT): Renamed from EXT_TAB.
11449 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
11450
11451 Avoid str[a-z]*, since <string.h> reserves that name space.
11452 Change all instances of "struniq" in names to "uniqstr", and
11453 likewise for "STRUNIQ" and "UNIQSTR".
11454 * src/uniqstr.c: Renamed from src/struniq.c.
11455 * src/uniqstr.h: Renamed from src/struniq.h.

11467 (N_EXPAND): Renamed from N_STRETCH.
11468

11471 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
11472 Remove; unused.
11473 * src/lalr.h (GOTO_NUMBER_MAXIMUM): Renamed from GOTO_NUMBER_MAX.
11474 * src/state.h (STATE_NUMBER_MAXIMUM): Renamed from STATE_NUMBER_MAX.
11475 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.

11481 Unnecessary casts removed from above defines.
11482
11483

11486 * src/vcg_defaults.h (G_NODE_ALIGNMENT): Renamed from
11487 G_NODE_ALIGNEMENT.
11488
11489
11490 * lib/timevar.c (timevar_report): Renamed from time_report,
11491 for consistency with other names.
11492 * lib/timevar.h (timevar_report): New decl.
11493 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11494
11495
11496 Sort include-file uses.
11497
11498 Reorder all include files under src to be in the order "system.h".
11499 then the ../lib include files in angle brackets (alphabetized),
11500 then the . include files in double-quotes (alphabetized). Fix
11501 dependency breakages encountered in this process, as follows:
11502 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11503 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11504 * src/state.h: Include "symtab.h".
11505
11506 2002-12-08 Paul Eggert <eggert@twinsun.com>
11507
11508 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11509 since this causes problems when __file__ contains character
11510 sequences like "@" that are treated specially by src/scan-skel.l.
11511 Instead, just use the file's basename. This fixes the bug
11512 reported by Martin Mokrejs in
11513 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11514
11515 2002-12-06 Paul Eggert <eggert@twinsun.com>
11516
11517 Add support for rules that do not have trailing semicolons, as
11518 POSIX requires. Improve the quality of locations in Bison
11519 diagnostics.
11520
11521 * src/location.c: Include <quotearg.h>.
11522 (empty_location): Now const.
11523 (location_print): New function. Follow the recommendation of the
11524 GNU Coding Standards for locations that span file boundaries.
11525 * src/location.h: Do not include <quotearg.h>; no longer needed.
11526 (boundary): New type.
11527 (location_t): Use it. This allows locations to span file boundaries.
11528 All member uses changed: file -> start.file or end.file (as needed),
11529 first_line -> start.line, first_column -> start.column,
11530 last_line -> end.line, last_column -> end.column.
11531 (equal_boundaries): New function.
11532 (LOCATION_RESET, LOCATION_STEP): Remove.
11533 (LOCATION_PRINT): Remove. All callers changed to use location_print.
11534 (empty_location): Now const.
11535 (location_print): New decl.
11536 * src/parse-gram.y (lloc_default): New function, which handles
11537 empty locations more accurately.
11538 (YYLLOC_DEFAULT): Use it.
11539 (%token COLON): Remove.
11540 (%token ID_COLON): New token.
11541 (rules): Use it.
11542 (declarations, rules): Remove trailing semicolon.
11543 (declaration, rules_or_grammar_declaration):
11544 Allow empty (";") declaration.
11545 (symbol_def): Remove empty actions; no longer needed.
11546 (rules_or_grammar_declaration): Remove trailing semicolon.
11547 (semi_colon.opt): Remove.
11548 * src/reader.h: Include location.h.
11549 (scanner_cursor): New decl.
11550 * src/reduce.c (nonterminals_reduce): Use warn_at rather than
11551 rolling our own.
11552 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11553 of *loc.
11554 (STEP): Remove. No longer needed, now that adjust_location does
11555 the work. All uses removed.
11556 (scanner_cursor): New var.
11557 (adjust_location): Renamed from extend_location. It now sets
11558 *loc and adjusts the scanner cursor. All uses changed.
11559 Don't bother testing for CR.
11560 (handle_syncline): Remove location arg; now updates scanner cursor.
11561 All callers changed.
11562 (unexpected_end_of_file): Now accepts start boundary of token or
11563 comment, not location. All callers changed. Update scanner cursor,
11564 not the location.
11565 (SC_AFTER_IDENTIFIER): New state.
11566 (context_state): Renamed from c_context. All uses changed.
11567 (id_loc, code_start, token_start): New local vars.
11568 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11569 processing of Yacc white space and equivalents here.
11570 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11571 instead of returning ID immediately, since we need to search for
11572 a subsequent colon.
11573 (<INITIAL>"'", "\""): Save token_start.
11574 (<INITIAL>"%{", "{", "%%"): Save code_start.
11575 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11576 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11577 BEGIN context_state at end, not INITIAL.
11578 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11579 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11580 Return correct token start.
11581 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11582 the start of a character, string or multiline comment is found.
11583 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11584 Reduction): Adjust reported locations to match the more-precise
11585 results now expected.
11586 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11587 * tests/reduce.at (Useless Rules, Reduced Automaton,
11588 Underivable Rules): Likewise.
11589 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11590 or "|"' now that so many other tokens are allowed by the new grammar.
11591
11592 * src/complain.h (current_file): Remove duplicate decl;
11593 current_file is now owned by files.h.
11594 * src/complain.c, src/scan-gram.l: Include files.h.
11595
11596 2002-12-06 Paul Eggert <eggert@twinsun.com>
11597
11598 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11599 promotes to int; it might be unsigned int.
11600 * data/yacc.c (yy_reduce_print): Likewise.
11601
11602 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11603 be #defined in the prologue, not in the Bison declarations.
11604 This fixes Debian Bug 102878, reported by Shaul Karl.
11605
11606 2002-12-02 Paul Eggert <eggert@twinsun.com>
11607
11608 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11609 * lib/strtoul.c: New file, from gnulib.
11610 This fixes a porting bug reported by Peter Klein in
11611 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11612
11613 2002-11-30 Paul Eggert <eggert@twinsun.com>
11614
11615 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11616 and put only a forward declaration in the prologue. This is for
11617 consistency with the other scanner helper functions.
11618
11619 Type clashes now generate warnings, not errors, since it
11620 appears that POSIX may allow some grammars with type clashes.
11621 * src/reader.c (grammar_current_rule_check): Warn about
11622 type clashes instead of complaining.
11623 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11624
11625 Add Yacc library, since POSIX requires it.
11626 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11627 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11628 * lib/main.c, lib/yyerror.c: New files.
11629
11630 gram_error can be static; it need not be extern.
11631 * src/reader.h (gram_error): Remove decl.
11632 * src/parse-gram.y (gram_error): Now static. Add static decl.
11633 (print_token_value): Omit parameter names from forward decl,
11634 for consistency.
11635
11636 2002-11-29 Paul Eggert <eggert@twinsun.com>
11637
11638 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11639 be declared before being used. E.g., one should typically
11640 declare them in the prologue. Use GNU coding style in examples.
11641 Put "const" consistently after the type it modifies. Mention
11642 that C99 supports "inline". Mention that yyerror traditionally
11643 returns "int".
11644
11645 %parse-param and %lex-param now take just one argument, the
11646 declaration; the argument name is deduced from the declaration.
11647
11648 * doc/bison.texinfo (Parser Function, Pure Calling, Error
11649 Reporting, Table of Symbols): Document this.
11650 * src/parse-gram.y (add_param): New function.
11651 (COMMA): Remove.
11652 (declaration): Implement new rule for %parse-param and %lex-param.
11653 * src/scan-gram.l: "," now elicits a warning, rather than being
11654 a token; this is more compatible with byacc.
11655 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
11656
11657 2002-11-27 Paul Eggert <eggert@twinsun.com>
11658
11659 Rename identifiers to avoid real and potential collisions.
11660
11661 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
11662 to avoid collision with lex macro described by Bruce Lilly in
11663 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
11664 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
11665 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
11666 * src/parse-gram.y (print_token_value): Renamed from yyprint.
11667 All uses changed.
11668 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
11669 The name "yycontrol" violates the name space rules, and this stuff
11670 wasn't being used anyway.
11671 (input): Remove action; this stuff wasn't being used.
11672 (gram_error): Rename local variable yylloc -> loc.
11673 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
11674 (YY_DECL): Don't use "yy" at start of local variables.
11675 All uses changed, e.g., yylloc -> loc.
11676 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
11677 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
11678 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
11679 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
11680
11681 * src/parse-gram.y (gram_error): loc is now const *.
11682 * src/reader.h (gram_error): Likewise.
11683
11684 2002-11-24 Paul Eggert <eggert@twinsun.com>
11685
11686 Version 1.75c.
11687
11688 * tests/actions.at (Actions after errors): Use an output format
11689 more similar to that of the Printers and Destructors test.
11690 Test the position of the ';' token too.
11691 (Printers and Destructors): Likewise.
11692 (Printers and Destructors: %glr-parser): Remove for now, to avoid
11693 unnecessarily alarming people when the test fails.
11694
11695 * data/yacc.c (yyerrlab1): Move this label down, so that the
11696 parser does not discard the lookahead token if the user code
11697 invokes YYERROR. This change is required for POSIX conformance.
11698
11699 * lib/error.c: Sync with gnulib.
11700
11701 2002-11-22 Paul Eggert <eggert@twinsun.com>
11702
11703 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
11704 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
11705 * lib/xmalloc.c: Likewise.
11706
11707 2002-11-20 Paul Eggert <eggert@twinsun.com>
11708
11709 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
11710
11711 2002-11-20 Paul Eggert <eggert@twinsun.com>
11712
11713 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
11714 should use `if (! x) abort ();' rather than `assert (x);', and
11715 anyway it's one less thing to worry about configuring.
11716
11717 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
11718 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
11719 and replace all instances of assert with abort.
11720 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
11721 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
11722

11726 hash_find_entry, hash_rehash, hash_insert): Likewise.
11727 * src/conflicts.c (resolve_sr_conflict): Likewise.
11728 * src/lalr.c (set_goto_map, map_goto): Likewise.
11729 * src/nullable.c (nullable_compute): Likewise.
11730 * src/output.c (prepare_rules, token_definitions_output): Likewise.
11731 * src/reader.c (packgram, reader): Likewise.
11732 * src/state.c (state_new, state_free, state_transitions_set,
11733 state_reduction_find): Likewise.
11734 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
11735 symbol_pack): Likewise.
11736 * src/tables.c (conflict_row, pack_vector): Likewise.
11737 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
11738 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11739 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
11740 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
11741
11742 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
11743 (ARGMATCH_CONSTRAINT): New macro.
11744 (ARGMATCH_ASSERT): Use it.
11745
11746 * src/system.h (verify): New macro.
11747 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
11748 rather than assert.
11749 * src/tables.c (tables_generate): Likewise.
11750
11751 * src/struniq.c (struniq_assert): Now returns void, and aborts
11752 if the assertion is false.
11753 (struniq_assert_p): Remove.
11754 * src/struniq.h: Likewise.
11755
11756 2002-11-18 Paul Eggert <eggert@twinsun.com>
11757
11758 * data/glr.c (yygetLRActions): Replace `yyindex' with
11759 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
11760 This fixes the regression with Sun ONE Studio 7 cc that I reported in
11761 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
11762
11763 2002-11-18 Akim Demaille <akim@epita.fr>
11764
11765 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
11766 space.
11767 From Tim Van Holder.
11768
11769 2002-11-17 Paul Eggert <eggert@twinsun.com>
11770
11771 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
11772 to "SyntaxError" for consistency with my 2002-11-15 change.
11773
11774 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
11775 not define to {}, since this breaks the common use of `YYDPRINTF
11776 ((...));' if a single statement is desired (e.g. before `else').
11777 Work around GCC warnings by surrounding corresponding calls with
11778 {} if needed.
11779 (yyhasResolvedValue): Remove unused function.
11780 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
11781 loop body.
11782 (yyreportSyntaxError): Renamed from yyreportParseError.
11783 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
11784 All uses changed.
11785 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
11786 extern when possible. Remove unused initializations.
11787
11788 2002-11-16 Akim Demaille <akim@epita.fr>
11789
11790 Augment the similarity between GLR and LALR traces.
11791
11792 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
11793 (YY_REDUCE_PRINT): New.
11794 (yyparse): Use them.
11795 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
11796 YYDPRINT here.
11797 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
11798 state reached after the reduction/recovery, since...
11799 (yyparse, yyprocessOneStack): Report the state we are entering in.
11800
11801 2002-11-16 Akim Demaille <akim@epita.fr>
11802
11803 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
11804 Add support for --trace=skeleton.
11805 * src/scan-skel.l: %option debug.
11806 Scan strings of non-@ or \n instead of character by character.
11807 (scan_skel): Handle trace_skeleton.
11808 (QPUTS): New.
11809 (@output_parser_name@, @output_header_name@): ``Restore'' their
11810 support (used to be M4 macros).
11811 * data/yacc.c: Quote larger chunks, a la glr.c.
11812 * data/lalr1.cc: Likewise.
11813 The header guards are no longer available, so use some other
11814 string than `YYLSP_NEEDED'.
11815
11816 2002-11-16 Akim Demaille <akim@epita.fr>
11817
11818 Make the ``Printers and Destructors'' test more verbose, taking
11819 `yacc.c''s behavior as (possibly wrong) reference.
11820
11821 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
11822 instead of fprint on stdout.
11823 Set and report the last_line of the symbols.
11824 Consistently display values and locations.
11825
11826 2002-11-16 Paul Eggert <eggert@twinsun.com>
11827
11828 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
11829
11830 2002-11-15 Paul Eggert <eggert@twinsun.com>
11831
11832 * tests/actions.at (Actions after errors): New test case.
11833
11834 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
11835 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
11836 tests/action.at, tests/calc.at, tests/conflicts.at,
11837 tests/cxx-type.at, tests/regression.at:
11838 "parse error" -> "syntax error" for POSIX compatibility.
11839 "parsing stack overflow..." -> "parser stack overflow" so
11840 that code matches Bison documentation.
11841
11842 2002-11-15 Akim Demaille <akim@epita.fr>
11843
11844 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
11845 take two BRACED_CODE, not two string_content.
11846 Free the scanner's obstack when we are done.
11847 (code_content): New.
11848 * tests/calc.at: Adjust.
11849 * doc/bison.texinfo: Adjust.
11850 Also, make sure to include the `,' for these declarations.
11851
11852 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
11853
11854 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
11855 definition; avoids potential autoreconf problems.
11856
11857 2002-11-15 Akim Demaille <akim@epita.fr>
11858
11859 Always check the value returned by yyparse.
11860
11861 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
11862 returned by yyparse.
11863 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
11864 Adjust calls.
11865 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
11866 returned by yyparse.
11867
11868 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11869
11870 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
11871 on input.at test.
11872
11873 2002-11-14 Paul Eggert <eggert@twinsun.com>
11874
11875 * src/output.c (output_skeleton): Call xfopen instead of
11876 duplicating xfopen's body.
11877
11878 Fix bugs reported by Nelson H. F. Beebe in
11879 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
11880
11881 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
11882 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
11883 Group compiler. Instead, use "$CC -E bar.c". Include the .h
11884 file twice in the grammar, as an extra check.
11885
11886 * tests/input.at (Torturing the Scanner): Surround the
11887 backslash-newline tests with "#if 0", to make it less likely that
11888 we'll run into compiler bugs. Bring back solitary \ inside
11889 comment, but add a closing comment to work around HP C bug. Don't
11890 test backslash-newline in C character constant.
11891
11892 2002-11-14 Akim Demaille <akim@epita.fr>
11893
11894 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
11895 status of the compiler.
11896 Calling `exit 1' is no longer needed.
11897 Reported by Nelson H. F. Beebe.
11898
11899 2002-11-14 Akim Demaille <akim@epita.fr>
11900
11901 * tests/atlocal.in (CPPFLAGS): We have config.h.
11902 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
11903 New.
11904 * tests/actions.at, tests/calc.at, tests/conflicts.at,
11905 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
11906 * tests/regression.at, tests/torture.at: Use them for all the
11907 grammars that are to be compiled.
11908 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
11909 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
11910 * doc/bison.texinfo (GLR Parsers): Document `inline'.
11911
11912 2002-11-14 Akim Demaille <akim@epita.fr>
11913
11914 * doc/bison.texinfo: Various formatting changes (alignments in
11915 samples, additional @group/@end group, GCS in samples.
11916 Use @deffn instead of simple @table to define the directives,
11917 macros, variables etc.
11918
11919 2002-11-13 Paul Eggert <eggert@twinsun.com>
11920
11921 Fix some bugs reported by Albert Chin-A-Young in
11922 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
11923
11924 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
11925 -o c"; the HP C compiler chatters during compilation.
11926 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
11927 * tests/headers.at (export YYLTYPE): Likewise.
11928
11929 * tests/input.at (Torturing the Scanner): Remove lines containing
11930 solitary backslashes, as they tickle a bug in the HP C compiler.
11931
11932 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
11933 comments, since they're not portable. Use GNU coding style.
11934
11935 2002-11-13 Akim Demaille <akim@epita.fr>
11936
11937 * data/yacc.c: Leave bigger chunks of quoted text.
11938 (YYDSYMPRINTF): New.
11939 Use it to report symbol activities.
11940 * data/glr.c (YYDSYMPRINTF): New.
11941 Use it.
11942
11943 2002-11-12 Paul Eggert <eggert@twinsun.com>
11944
11945 Version 1.75b.
11946
11947 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
11948 (yyglrReduce): Return yyok, not 0.
11949 This should avoid the enumerated-type warnings reported
11950 by Nelson H. F. Beebe in
11951 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
11952
11953 * lib/bbitset.h (BITSET_INLINE): Remove.
11954 * lib/bitset.h [! BITSET_INLINE]: Remove.
11955 (bitset_set, bitset_reset, bitset_test): Rename local vars
11956 to avoid shadowing warnings by GCC.
11957
11958 * data/glr.c (inline): Remove #define. It's the user's
11959 responsibility to #define it away, just like 'const'.
11960 This fixes one of the bugs reported by Nelson H. F. Beebe in
11961 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
11962
11963 * Makefile.maint (po-check): Scan .l and .y files instead of the
11964 .c and the .h files that they generate. This fixes the bug
11965 reported by Tim Van Holder in:
11966 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
11967 Look for N_ as well as for _. Try to avoid matching #define for
11968 N_ and _.
11969 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
11970 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
11971 * src/scan-gram.l: Revamp regular expressions so that " and '
11972 do not confuse xgettext.
11973
11974 * src/struniq.h (struniq_new): Do not declare the return type
11975 to be 'const'; this violates the C standard.
11976 * src/struniq.c (struniq_new): Likewise.
11977
11978 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
11979
11980 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
11981 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
11982 linker.
11983
11984 2002-11-12 Akim Demaille <akim@epita.fr>
11985
11986 * Makefile.maint: Sync with Autoconf:

11988
11989 2002-11-12 Akim Demaille <akim@epita.fr>
11990
11991 * po/POTFILES.in (src/lalr.c, src/state.c): Remove
11992
11993 2002-11-12 Akim Demaille <akim@epita.fr>
11994
11995 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
11996 locations.
11997
11998 2002-11-12 Akim Demaille <akim@epita.fr>
11999
12000 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
12001 not yyvalue.
12002
12003 2002-11-12 Akim Demaille <akim@epita.fr>
12004
12005 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.
12006 Use it to test the GLR parser.
12007
12008 2002-11-12 Akim Demaille <akim@epita.fr>
12009
12010 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
12011 defines it.
12012 * data/glr.c (yystos): New.
12013 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
12014 (YYDSYMPRINT): New.
12015 (yyval): Don't define it, it is handled via M4.
12016 (yyrecoverParseError): Free verbosely the discarded symbols.
12017 * data/yacc.c (yysymprint): Remove, rather...
12018 (b4_yysymprint_generate): invoke.
12019 * data/c.m4 (b4_yysymprint_generate): New.
12020 Accept pointers as arguments, as opposed to the version from
12021 yacc.c.
12022 (b4_yydestruct_generate): Likewise.
12023 * tests/cations.at (Printers and Destructors): Use Bison directives
12024 instead of CPP macros.
12025 Don't rely on internal details.
12026
12027 2002-11-12 Akim Demaille <akim@epita.fr>
12028
12029 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
12030 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
12031 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
12032 it against YYEMPTY and so forth), work on yytoken (i.e., set
12033 it to YYEMPTY etc.).
12034 (yydestruct): Replace with a b4_yydestruct_generate invocation.
12035 (b4_symbol_actions): Remove.
12036 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
12037 for 0, end-of-input.
12038
12039 2002-11-12 Akim Demaille <akim@epita.fr>
12040
12041 * doc/bison.texinfo (Destructor Decl): New.
12042
12043 2002-11-12 Akim Demaille <akim@epita.fr>
12044
12045 * src/tables.c (tables_generate): Use free for pointers that
12046 cannot be NULL, not XFREE.
12047 (pack_vector): Use assert, not fatal, for bound violations.
12048 * src/state.c (state_new): Likewise.
12049 * src/reader.c (reader): Likewise.
12050 * src/lalr.c (set_goto_map): Likewise.
12051 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
12052 the file name.
12053
12054 2002-11-12 Akim Demaille <akim@epita.fr>
12055
12056 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
12057 Restore.
12058 * src/scan-gram.l (last_string): Is global to the file, not to
12059 yylex.
12060 * src/parse-gram.y (input): Don't append the epilogue here,
12061 (epilogue.opt): do it here, and free the scanner's obstack.
12062 * src/reader.c (epilogue_set): Rename as...
12063 (epilogue_augment): this.
12064 * data/c.m4 (b4_epilogue): Defaults to empty.
12065
12066 2002-11-12 Akim Demaille <akim@epita.fr>
12067
12068 * src/getargs.c (long_options): Remove duplicates.
12069 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:
12070 Remove.
12071 * doc/bison.rnh: Remove.
12072 * doc/bison.texinfo (VMS Invocation): Remove.
12073
12074 2002-11-12 Akim Demaille <akim@epita.fr>
12075
12076 * src/struniq.h, src/struniq.c (struniq_t): Is const.
12077 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
12078
12079 Use struniq for symbols.
12080
12081 * src/symtab.h (symbol_t): The tag member is a struniq.
12082 (symbol_type_set): Adjust.
12083 * src/symtab.c (symbol_new): Takes a struniq.
12084 (symbol_free): Don't free the tag member.
12085 (hash_compare_symbol_t, hash_symbol_t): Rename as...
12086 (hash_compare_symbol, hash_symbol): these.
12087 Use the fact that tags as struniqs.
12088 (symbol_get): Use struniq_new.
12089 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
12090 Returns a strniq.
12091 * src/reader.h (merger_list, grammar_currentmerge_set): The name
12092 and type members are struniqs.
12093 * src/reader.c (get_merge_function)
12094 (grammar_current_rule_merge_set): Adjust.
12095 (TYPE, current_type): Are struniq.
12096
12097 Use struniq for file names.
12098
12099 * src/files.h, src/files.c (infile): Split into...
12100 (grammar_file, current_file): these.
12101 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
12102 * src/reduce.c (reduce_print): Likewise.
12103 * src/getargs.c (getargs): Likewise.
12104 * src/complain.h, src/complain.c: Likewise.
12105 * src/main.c (main): Call struniqs_new early enough to use it for
12106 file names.
12107 Don't free the input file name.
12108
12109 2002-11-12 Akim Demaille <akim@epita.fr>
12110
12111 * src/symtab.c (symbol_free): Remove dead deactivated code:
12112 type_name are properly removed.
12113 Don't use XFREE to free items that cannot be NULL.
12114 * src/struniq.h, src/struniq.c: New.
12115 * src/main.c (main): Initialize/free struniqs.
12116 * src/parse-gram.y (%union): Add astruniq member.
12117 (yyprint): Adjust.

12121
12122 2002-11-11 Paul Eggert <eggert@twinsun.com>
12123
12124 Revamp to fix many (but not all) of the C- and M4-related quoting
12125 problems. Among other things, this fixes the Bison bug reported
12126 by Jan Hubicka when processing the Bash grammar; see:
12127 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12128
12129 Use new @ escapes consistently. Represent brackets with @{ and @}
12130 rather than @<:@ and @:>@, since this works a bit better with dumb
12131 editors like vi. Represent @ with @@, since @ is now consistently
12132 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12133 __ofile__, to avoid unexpected expansions. Similarly, use @output
12134 rather than #output.
12135
12136 * data/c.m4 (b4_copyright): Omit file name from comment, since
12137 the file name could contain "*/".
12138 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12139 be quoted. All uses changed.
12140
12141 * data/glr.c: Use new @ escapes consistently.
12142 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12143 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12144 Remove, since they couldn't handle arbitrary characters in file
12145 names.
12146 * data/lalr1.cc: Likewise.
12147 * data/yacc.c: Likewise.
12148
12149 * src/files.c (output_infix): Remove; all uses removed.
12150 * src/files.h: Likewise.
12151
12152 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12153 mishandled funny characters in file names, and anyway it isn't
12154 needed any more.
12155 * data/yacc.c: Likewise.
12156 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12157
12158 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12159 * data/yacc.c: Likewise.
12160
12161 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12162 strings now.
12163 (muscle_init): Quote filename as a C string.
12164 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12165 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12166 * src/output.c (escaped_file_name_output): New function.
12167 (prepare_symbols): Quote tokens for M4.
12168 (prepare): Don't insert output_infix, output_prefix,
12169 output_parser_name, output_header_name; this is now down by scan-skel.
12170 Insert skeleton as a C string.
12171
12172 * src/output.c (user_actions_output, symbol_destructors_output,
12173 symbol_printers_output): Quote filenames for C and M4.
12174 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12175
12176 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12177 escapes other than \\ and \'; this simplifies the code.
12178 (<SC_STRING>): Likewise, for \\ and \".
12179 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12180 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12181 Use new escapes @{ and @} for [ and ].
12182
12183 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12184 them with auto vars.
12185 Switch to new escape scheme, where @ is the escape character uniformly.
12186 Abort if a stray escape character is found. Avoid unbounded input
12187 buffer when parsing non-escaped text.
12188
12189 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12190 __oline__, #output, $@, and @{ do not have unintended meanings.
12191
12192 2002-11-09 Paul Eggert <eggert@twinsun.com>
12193
12194 Fix the test failure due to GCC warnings described in
12195 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12196 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12197 evaluate to 0 if it's impossible for NINF to be in the respective
12198 table.
12199 (yygetLRActions, yyrecoverParseError): Use them.
12200
12201 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12202 counted in the token inserted at end of file. Now takes
12203 location_t *, not location_t, so that the location can be
12204 adjusted. All uses changed.
12205
12206 * tests/regression.at (Invalid inputs): Adjust wording in
12207 diagnostic to match the new behavior.
12208
12209 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
12210 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12211 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12212 abort ();'. This reduces the runtime of the "Many lookaheads"
12213 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
12214 GCC 3.2.
12215
12216 2002-11-07 Paul Eggert <eggert@twinsun.com>
12217
12218 * src/parse-gram.y (CHARACTER): Remove unused token.
12219 All uses removed.
12220
12221 * src/scan-gram.l: Remove stack option. We no longer use the
12222 stack, since the stack was never deeper than 1; instead, use the
12223 new auto var c_context to record the stacked value.
12224
12225 Remove nounput option. At an unexpected end of file, we now unput
12226 the minimal input necessary to end cleanly; this simplifies the
12227 code.
12228
12229 Avoid unbounded token sizes where this is easy.
12230
12231 (unexpected_end_of_file): New function.
12232 Use it to systematize the error message on unexpected EOF.
12233 (last-string): Now auto, not static.
12234 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
12235 (scanner_last_string_free): Remove; not used.
12236 (percent_percent_count): Move decl to just before use.
12237 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12238 not the (never otherwised-used) CHARACTER.
12239
12240 2002-11-07 Akim Demaille <akim@epita.fr>
12241
12242 Let yyerror always receive the msg as last argument, so that
12243 yyerror can be variadic.
12244
12245 * data/yacc.c (b4_yyerror_args): New.
12246 Use it when calling yyerror.
12247 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
12248 Use it when calling yyerror.
12249 * doc/bison.texinfo (Error Reporting): Adjust.
12250 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
12251 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
12252
12253 2002-11-06 Akim Demaille <akim@epita.fr>
12254
12255 #line should have quoted strings.
12256 Ideally, this should be done by m4_quotearg.
12257
12258 * src/scan-skel.l: Include quotearg.h.
12259 Quote __ofile__.
12260 * src/output.c (symbol_printers_output)
12261 (symbol_destructors_output): Quote the file name.
12262
12263 2002-11-06 Akim Demaille <akim@epita.fr>
12264
12265 * tests/regression.at (Invalid inputs): Adjust to the recent
12266 messages.
12267
12268 2002-11-06 Akim Demaille <akim@epita.fr>
12269
12270 Restore --no-lines.
12271 Reported by Jim Kent.
12272
12273 * data/c.m4 (b4_syncline): New.
12274 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
12275 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
12276 * src/output.c (user_actions_output): Likewise.
12277 (prepare): Define 'b4_synclines_flag'.
12278 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
12279
12280 2002-11-06 Akim Demaille <akim@epita.fr>
12281
12282 * src/main.c (main): Free `infile'.
12283 * src/scan-gram.l (handle_syncline): New.
12284 Recognize `#line'.
12285 * src/output.c (user_actions_output, symbol_destructors_output)
12286 (symbol_printers_output): Use the location's file name, not
12287 infile.
12288 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12289
12290 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12291
12292 * src/tables.c (matching_state): Don't allow states to match if
12293 either has GLR conflict entries.
12294
12295 2002-11-05 Paul Eggert <eggert@twinsun.com>
12296
12297 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12298 "integer out of range" rather than "invalid value".
12299 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12300 accordingly.
12301
12302 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12303 Also, remove one static variable in the scanner.
12304
12305 * src/scan-gram.l (braces_level): Now auto, not static.
12306 Initialize to zero if the compiler is being picky.
12307 (INITIAL): Clear braces_level instead of incrementing it.
12308 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
12309 as POSIX 1003.1-2001 requires.
12310 * src/system.h (IF_LINT): New macro, taken from coreutils.
12311 * configure.ac: Define "lint" if --enable-gcc-warnings.
12312
12313 2002-11-05 Akim Demaille <akim@epita.fr>
12314
12315 * src/scan-gram.l: When it starts with `%', complain about the
12316 whole directive, not just that `invalid character: %'.
12317
12318 2002-11-04 Akim Demaille <akim@epita.fr>
12319
12320 * Makefile.maint: Update from Autoconf.
12321 (update, cvs-update, po-update, do-po-update): New.
12322
12323 2002-11-04 Akim Demaille <akim@epita.fr>
12324
12325 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
12326 and yyerror.
12327 Have yyerror `use' its arguments.
12328 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
12329 returns true when location & yacc & pure & parse-param.
12330 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
12331
12332 2002-11-04 Akim Demaille <akim@epita.fr>
12333
12334 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
12335 clashes.
12336 * src/scan-gram.l: Use [\'] instead of ['] to pacify
12337 font-lock-mode.
12338 Use complain_at.
12339 Use quote, not quote_n since LOCATION_PRINT no longer uses the
12340 slot 0.
12341
12342 2002-11-03 Paul Eggert <eggert@twinsun.com>
12343
12344 * src/reader.c (get_merge_function, grammar_current_rule_check):
12345 Use consistent diagnostics for reporting type name clashes.
12346 Quote the types with <>, for consistency with Yacc.
12347 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12348
12349 2002-11-03 Akim Demaille <akim@epita.fr>
12350
12351 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
12352 New.
12353 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
12354 (b4_parse_param): Remove.
12355 Use b4_identification.

12357 * data/glr.m4 (b4_parse_param): Remove.
12358 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)

12360 Use b4_identification.
12361 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
12362 b4_user_formals and b4_user_args.
12363 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12364 (yyreportAmbiguity): When using a pure parser, also need
12365 the location, and the parse-params.
12366 Adjust callers.
12367 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
12368 When using a pure parser, also need the parse-params.
12369 Adjust callers.
12370 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
12371 (%pure-parser + %parse-param) LALR and GLR parsers.
12372 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12373 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12374 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
12375 (_AT_DATA_CALC_Y): Equip for purity of yyerror.

12378 * doc/bison.texinfo: Untabify the whole file.
12379 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
12380 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
12381 (Error Reporting): Adjust to these new directives.
12382 Document %error-verbose, deprecate YYERROR_VERBOSE.
12383
12384 2002-11-03 Akim Demaille <akim@epita.fr>
12385
12386 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
12387 AT_CHECK_CALC_GLR invocations to use % directives, instead of
12388 command line options.
12389 * tests/cxx-type.at: Formatting changes.
12390
12391 2002-11-03 Paul Eggert <eggert@twinsun.com>
12392
12393 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
12394 to count columns correctly, and to check for invalid inputs.
12395
12396 Use mbsnwidth to count columns correctly. Account for tabs, too.
12397 Include mbswidth.h.
12398 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
12399 (extend_location): New function.
12400 (YY_LINES): Remove.
12401
12402 Handle CRLF in C code rather than in Lex code.
12403 (YY_INPUT): New macro.
12404 (no_cr_read): New function.
12405
12406 Scan UCNs, even though we don't fully handle them yet.
12407 (convert_ucn_to_byte): New function.
12408
12409 Handle backslash-newline correctly in C code.
12410 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
12411 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
12412 all uses changed.
12413 (tag, splice): New EREs. Do not allow NUL or newline in tags.
12414 Use {splice} wherever C allows backslash-newline.
12415 YY_STEP after space, newline, vertical-tab.
12416 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
12417
12418 (letter, id): Don't assume ASCII; e.g., spell out a-z.
12419
12420 ({int}, handle_action_dollar, handle_action_at): Check for integer
12421 overflow.
12422
12423 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12424
12425 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
12426 as well as \000. Check for UCHAR_MAX, not 255.
12427 Allow \x with an arbitrary positive number of digits, as in C.
12428 Check for overflow here.
12429 Allow \? and UCNs, for compatibility with C.
12430
12431 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12432 with quote slot used by complain_at.
12433
12434 * tests/input.at: Add tests for backslash-newline, m4 quotes
12435 in symbols, long literals, and funny escapes in strings.
12436
12437 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
12438 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
12439 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
12440 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
12441 * m4/mbswidth.m4: New file, from GNU coreutils.
12442
12443 * doc/bison.texinfo (Grammar Outline): Document // comments.
12444 (Symbols): Document that trigraphs have no special meaning in Bison,
12445 nor is backslash-newline allowed.
12446 (Actions): Document that trigraphs have no special meaning.
12447
12448 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
12449 no longer used.
12450
12451 2002-11-02 Paul Eggert <eggert@twinsun.com>
12452
12453 * src/reader.c: Don't include quote.h; not needed.
12454 (get_merge_function): Reword warning to be consistent with
12455 type clash diagnostic in grammar_current_rule_check.
12456
12457 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
12458 bug in trigraph handling.
12459
12460 * src/output.c (prepare_symbols): When printing token names,
12461 escape "[" as "@<:@" and likewise for "]".
12462
12463 * src/system.h (errno): Remove declaration, as we are now
12464 assuming C89 or better, and C89 guarantees errno.
12465
12466 2002-10-30 Paul Eggert <eggert@twinsun.com>
12467
12468 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12469 Check for close failures.
12470 * src/files.h (xfclose): Return void, not int, since it always
12471 returned zero.
12472 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12473 indicates one.
12474 * src/output.c (output_skeleton): Use xfclose rather than fclose
12475 and ferror. xfclose now checks ferror.
12476
12477 * data/glr.c (YYLEFTMOST_STATE): Remove.
12478 (yyreportTree): Use a stack-based leftmost state. This avoids
12479 our continuing battles with bogus warnings about initializers.
12480
12481 2002-10-30 Akim Demaille <akim@epita.fr>
12482
12483 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
12484 #if.
12485
12486 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12487
12488 * tests/glr-regr1.at: New test for reported regressions.
12489 * tests/testsuite.at: Add glr-regr1.at test.
12490 * tests/Makefile.am: Add glr-regr1.at test.
12491
12492 2002-10-24 Paul Eggert <eggert@twinsun.com>
12493
12494 Version 1.75a.
12495
12496 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12497 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12498 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12499 Don't assume strdup exists; POSIX says its an XSI extension.
12500 Check for buffer overflow on input.
12501
12502 2002-10-24 Akim Demaille <akim@epita.fr>
12503
12504 * src/output.c (output_skeleton): Don't disable M4sugar comments
12505 too soon: it results in comments being expanded.
12506 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12507 first output.
12508
12509 2002-10-24 Akim Demaille <akim@epita.fr>
12510
12511 * data/yacc.c (m4_int_type): New.
12512 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12513 char' as only yacc.c wants K&R portability.
12514 * data/glr.c (yysigned_char): Remove.
12515 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12516 Reported by Quoc Peyrot.
12517
12518 2002-10-23 Paul Eggert <eggert@twinsun.com>
12519
12520 * src/main.c (main): With --trace=time, report times even if a
12521 non-fatal error occurs. Formerly, the times were reported in some
12522 such cases but not in others.
12523 * src/reader.c (reader): Just return if a complaint has been issued,
12524 instead of exiting, so that 'main' can report times.
12525
12526 2002-10-22 Akim Demaille <akim@epita.fr>
12527
12528 * src/system.h: Include sys/types.
12529 Reported by Bert Deknuydt.
12530
12531 2002-10-23 Paul Eggert <eggert@twinsun.com>
12532
12533 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12534 Suggested by Art Haas.
12535
12536 2002-10-22 Paul Eggert <eggert@twinsun.com>
12537
12538 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12539 decl; not needed any more.
12540 * src/main.c (main): Use return to exit, undoing yesterday's change.
12541 The last OS that we could find where this wouldn't work is
12542 SunOS 3.5, and that's too old to worry about now.
12543
12544 * data/glr.c (struct yyltype): Define members even when not
12545 doing locations. This is more consistent with yacc.c, and it
12546 works around the following bug reports:
12547 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12548 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12549
12550 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12551 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12552 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12553
12554 2002-10-22 Akim Demaille <akim@epita.fr>
12555
12556 * data/README: New.
12557
12558 2002-10-21 Paul Eggert <eggert@twinsun.com>
12559
12560 Be consistent about 'bool'; the old code used an enum in one
12561 module and an int in another, and this violates the C standard.
12562 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12563 * configure.ac (AC_HEADER_STDBOOL): Add.
12564 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12565 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12566 * src/symtab.c (hash_compare_symbol_t): Likewise.
12567 * src/system.h (bool, false, true): Use a definition consistent
12568 with ../lib/hash.c. All uses changed.
12569
12570 * src/complain.c (warning_issued): Renamed from warn_message_count,
12571 so that we needn't worry about integer overflow (!).
12572 Now of type bool. All uses changed.
12573 (complaint_issued): Renamed from complain_message_count; likewise.
12574
12575 * src/main.c (main): Use exit to exit with failure.
12576
12577 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12578 rather than 1 and 0.
12579 * src/main.c (main): Likewise.
12580 * src/getargs.c (getargs): Likewise.
12581 * src/reader.c (reader): Likewise.
12582
12583 * src/getarg.c (getargs): Remove duplicate code for
12584 "Try `bison --help'".
12585
12586 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12587 What was that "2" for?
12588
12589 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12590 * src/getargs.c (usage): Likewise.
12591
12592 * src/getargs.c (getargs): When there are too few operands, report
12593 the last one. When there are too many, report the first extra
12594 one. This is how diffutils does it.
12595
12596 2002-10-20 Paul Eggert <eggert@twinsun.com>
12597
12598 Remove K&R vestiges.
12599 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12600 * src/complain.c (VA_START): Remove. Assume prototypes.
12601 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12602 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12603 fatal): Assume prototypes.
12604 * src/complain.h: Assume prototypes.
12605 * src/system.h (PARAMS): Remove.
12606 Include <limits.h> unconditionally, since it's guaranteeed even
12607 for a freestanding C89 compiler.
12608 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12609 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12610
12611 2002-10-20 Akim Demaille <akim@epita.fr>
12612
12613 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12614 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
12615 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
12616 (yyresolveStates, yyresolveAction, yyresolveStack)
12617 (yyprocessOneStack): Use them.
12618 (yy_reduce_print): New.
12619 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12620
12621 2002-10-20 Akim Demaille <akim@epita.fr>
12622
12623 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12624 arguments and output `void'.
12625 (b4_c_function): Rename as...
12626 (b4_c_function_def): this.
12627 (b4_c_function_decl, b4_c_ansi_function_def)
12628 (b4_c_ansi_function_decl): New.
12629 Change the interpretation of the arguments: before `int, foo', now
12630 `int foo, foo'.
12631 * data/yacc.c (yyparse): Prototype and define thanks to these.
12632 Adjust b4_c_function_def uses.
12633 * data/glr.c (yyparse): Likewise, but ANSI only.
12634
12635 2002-10-20 Akim Demaille <akim@epita.fr>
12636
12637 * src/output.c (prepare): Move the definition of `tokens_number',
12638 `nterms_number', `undef_token_number', `user_token_number_max'
12639 to...
12640 (prepare_tokens): Here.
12641 (prepare_tokens): Rename as...
12642 (prepare_symbols): this.
12643 (prepare): Move the definition of `rules_number' to...
12644 (prepare_rules): here.
12645 (prepare): Move the definition of `last', `final_state_number',
12646 `states_number' to...
12647 (prepare_states): here.
12648 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
12649
12650 2002-10-20 Akim Demaille <akim@epita.fr>
12651
12652 * src/tables.h, src/tables.c, src/output.c: Comment changes.
12653
12654 2002-10-20 Akim Demaille <akim@epita.fr>
12655
12656 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
12657 * data/c.m4: here.
12658
12659 2002-10-20 Akim Demaille <akim@epita.fr>
12660
12661 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
12662 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
12663 `pair'.
12664 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
12665 `name' to...
12666 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
12667 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
12668 These.
12669
12670 2002-10-19 Paul Eggert <eggert@twinsun.com>
12671
12672 Do not create a temporary file, as that involves security and
12673 cleanup headaches. Instead, use a pair of pipes.
12674 Derived from a suggestion by Florian Krohm.
12675 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
12676 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
12677 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
12678 (BISON_PREREQ_SUBPIPE): Add.
12679 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
12680 Add subpipe.h, subpipe.c.
12681 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
12682 * po/POTFILES.in: Add lib/subpipe.c.
12683 * src/output.c: Include "subpipe.h".
12684 (m4_invoke): Remove decl.
12685 (scan_skel): New decl.
12686 (output_skeleton): Use pipe rather than temporary file for m4 input.
12687 Check that m4sugar.m4 is readable, to avoid deadlock.
12688 Check for pipe I/O error.
12689 * src/scan-skel.l (readpipe): Remove decl.
12690 (scan_skel): New function, to be used in place of m4_invoke.
12691 Read from stream rather than file.
12692
12693 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
12694 float, as this generates a warning on Solaris 8 + GCC 3.2 with
12695 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
12696 this generates a more-accurate value anyway.
12697
12698 * lib/timevar.c (timervar_accumulate): Rename locals to
12699 avoid confusion with similarly-named more-global.
12700 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
12701
12702 * src/output.c (prepare): Use xstrdup to convert char const *
12703 to char *, to avoid GCC warning.
12704
12705 2002-10-19 Akim Demaille <akim@epita.fr>
12706
12707 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
12708 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
12709 Use them to have `calc.y' ready for %pure-parser.
12710 * data/yacc.c (YYLEX): Pass a yylex return type to
12711 b4_c_function_call.
12712
12713 2002-10-19 Akim Demaille <akim@epita.fr>
12714
12715 Prototype support of %lex-param and %parse-param.
12716
12717 * src/parse-gram.y: Add the definition of the %lex-param and
12718 %parse-param tokens, plus their rules.
12719 Drop the `_' version of %glr-parser.
12720 Add the "," token.
12721 * src/scan-gram.l (INITIAL): Scan them.
12722 * src/muscle_tab.c: Comment changes.
12723 (muscle_insert, muscle_find): Rename `pair' as `probe'.
12724 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
12725 (muscle_entry_s): The `value' member is no longer const.
12726 Adjust all dependencies.
12727 * src/muscle_tab.c (muscle_init): Adjust: use
12728 MUSCLE_INSERT_STRING.
12729 Initialize the obstack earlier.
12730 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
12731 (muscle_pair_list_grow): New.
12732 * data/c.m4 (b4_c_function_call, b4_c_args): New.
12733 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
12734 * tests/calc.at: Use %locations, not --locations.
12735 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
12736
12737 2002-10-19 Akim Demaille <akim@epita.fr>
12738
12739 * src/getargs.c (usage): Take status as argument and exit
12740 accordingly.
12741 Report the traditional `Try ... --help' message when status != 0.
12742 (usage, version): Don't take a FILE * as arg, it is pointless.
12743 (getargs): When there is an incorrect number of arguments, make it
12744 an error, and report it GNUlically thanks to `usage ()'.
12745
12746 2002-10-18 Paul Eggert <eggert@twinsun.com>
12747
12748 * data/glr.c (yyreportParseError): Don't assume that sprintf
12749 yields the length of the printed string, as this is not true
12750 on SunOS 4.1.4. Reported by Peter Klein.
12751
12752 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
12753 * tests/conflicts.at (%nonassoc and eof): Likewise.
12754 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
12755
12756 2002-10-17 Akim Demaille <akim@epita.fr>

12758 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
12759 * src/getargs.c (trace_types, trace_args): Adjust.
12760 * src/reader.c (grammar_current_rule_prec_set)
12761 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
12762 Standardize error messages.
12763 And s/@prec/%prec/!
12764 (reader): Use trace_flag to enable scanner/parser debugging,
12765 instead of an adhoc scheme.
12766 * src/scan-gram.l: Remove trailing debugging code.
12767
12768 2002-10-16 Paul Eggert <eggert@twinsun.com>
12769
12770 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
12771 MUSCLE_TAB_H.
12772
12773 * NEWS: Officially drop support for building Bison with K&R C,
12774 since it didn't work anyway and it's not worth worrying about.
12775 * Makefile.maint (wget_files): Remove ansi2knr.c.
12776 (ansi2knr.c-url_prefix): Remove.
12777 * lib/.cvsignore: Remove ansi2knr, ansi2knr.*.

12780
12781 2002-10-15 Paul Eggert <eggert@twinsun.com>
12782
12783 Stop using the "enum_" trick for K&R-style function definitions;
12784 it confused me, and I was the author! Instead, assume that people
12785 who want to use K&R C compilers (when using these modules in GCC,
12786 perhaps?) will run ansi2knr.
12787
12788 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
12789 All uses of "enum_" changed to "enum ".

12801 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):

12860
12861 2002-10-14 Akim Demaille <akim@epita.fr>
12862
12863 * tests/Makefile.am (maintainer-check-posix): New.
12864
12865 2002-10-14 Akim Demaille <akim@epita.fr>
12866
12867 * data/glr.c [YYDEBUG] (YYLEFTMOST_STATE): Initialize the yyloc
12868 member.
12869
12870 2002-10-14 Akim Demaille <akim@epita.fr>
12871
12872 * src/tables.c (table_ninf_remap): base -> tab.
12873 Reported by Matt Rosing.
12874
12875 2002-10-14 Paul Eggert <eggert@twinsun.com>
12876
12877 * tests/action.at, tests/calc.at, tests/conflicts.at,
12878 tests/cxx-type.at, tests/headers.at, tests/input.at,
12879 tests/regression.at, tests/synclines.at, tests/torture.at:
12880 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
12881 so that the tests still work even if POSIXLY_CORRECT is set.
12882 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
12883
12884 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
12885 for portability to K&R hosts. Fix typo: signed char is guaranteed
12886 only to 127, not to 128.
12887 * data/glr.c (yysigned_char): New type.
12888 * data/yacc.c (yysigned_char): Likewise.
12889 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
12890
12891 2002-10-13 Paul Eggert <eggert@twinsun.com>
12892
12893 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
12894 true due to limited range of data type" warning from GCC.
12895
12896 * data/c.m4 (b4_token_defines): Protect against double-inclusion
12897 by wrapping enum yytokentype's definition inside #ifndef
12898 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
12899
12900 2002-10-13 Akim Demaille <akim@epita.fr>
12901
12902 * data/glr.c (yyglrShiftDefer, yyaddDeferredAction, yydoAction):
12903 Un yy- yyrhs to avoid the name clash with the global YYRHS.
12904
12905 2002-10-13 Akim Demaille <akim@epita.fr>
12906
12907 * Makefile.maint: Update from Autoconf 2.54.

12909
12910 2002-10-13 Akim Demaille <akim@epita.fr>
12911
12912 * src/print.c (print_state): Separate the list of solved conflicts
12913 from the other items.

12917
12918 Let nondeterministic skeletons be usable with deterministic
12919 tables.
12920
12921 With the patch, GAWK compiled by GCC without -O2 passes its test
12922 suite using a GLR parser driven by LALR tables. It fails with -O2
12923 because `struct stat' gives two different answers on my machine:
12924 88 (definition of an auto var) and later 96 (memset on this var).
12925 Hence the stack is badly corrumpted. The headers inclusion is to
12926 blame: if I move the awk.h inclusion before GLR's system header
12927 inclusion, the two struct stat have the same size.
12928
12929 * src/tables.c (pack_table): Always create conflict_table.
12930 (token_actions): Always create conflict_list.
12931 * data/glr.c (YYFLAG): Remove, unused.
12932
12933 2002-10-13 Akim Demaille <akim@epita.fr>
12934
12935 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
12936 (O0FLAGS): New.
12937 (VALGRIND, GXX): New.
12938 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
12939 * tests/bison.in: Run $PREBISON a pre-command.
12940 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
12941 (maintainer-check-g++): New.
12942 * Makefile.am (maintainer-check): New.
12943
12944 2002-10-13 Akim Demaille <akim@epita.fr>
12945
12946 * data/glr.c: Formatting changes.
12947 Tweak some trace messages to match yacc.c's.
12948
12949 2002-10-13 Akim Demaille <akim@epita.fr>
12950
12951 GLR parsers sometimes raise parse errors instead of performing the
12952 default reduction.
12953 Reported by Charles-Henry de Boysson.
12954
12955 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
12956 check the length of the traces when %glr.
12957 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
12958 GLR's traces.
12959 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
12960 Test GLR parsers.
12961 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
12962 (yyltype): Remove the yy prefix from the member names.
12963 (yytable): Complete its comment.
12964 (yygetLRActions): Map error action number from YYTABLE from
12965 YYTABLE_NINF to 0.
12966 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
12967 (which was a bug: it should have been YYTABEL_NINF, and yet it was
12968 not satisfying as we could compare an YYACTION computed from
12969 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
12970 only value for error actions.
12971 (yyreportParseError): In verbose parse error messages, don't issue
12972 `error' in the list of expected tokens.
12973 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
12974 next action to perform to match glr.c's decoding.
12975 (yytable): Complete its comment.
12976
12977 2002-10-13 Paul Eggert <eggert@twinsun.com>
12978
12979 Fix problem reported by Henrik Grubbstroem in
12980 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
12981 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
12982 because the Bison parser reads the second action before reducing
12983 the first one.
12984 * src/scan-gram.l (rule_length): New static var.
12985 Use it to keep track of the rule length in the scanner, since
12986 we can't expect the parser to be in lock-step sync with the scanner.
12987 (handle_action_dollar, handle_action_at): Use this var.
12988 * tests/actions.at (Exotic Dollars): Test for the problem.
12989
12990 2002-10-12 Paul Eggert <eggert@twinsun.com>
12991
12992 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
12993 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
12994 Include <sys/time.h> when checking for clock_t and struct tms.
12995 Use same include order as source.
12996 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
12997 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
12998
12999 * lib/timevar.c: Update copyright date and clarify comments.
13000 (get_time) [IN_GCC]: Keep the GCC version for reference.
13001
13002 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13003 GCC version as of today, then merge Bison's changes.
13004 Change "GCC" to "Bison" in copyright notice. timevar.def's
13005 author is Akim, so change that too.
13006
13007 * src/reader.c (grammar_current_rule_check):
13008 Don't worry about the default action if $$ is untyped.
13009 Prevents bogus warnings reported by Jim Gifford in
13010 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13011
13012 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13013 * data/glr.c, data/lalr1.cc, data/yacc.c:
13014 Output token definitions before the first part of user declarations.
13015 Fixes compatibility problem reported by Jim Gifford for kbd in
13016 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13017
13018 2002-10-11 Paul Eggert <eggert@twinsun.com>
13019
13020 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13021 (yyparse): here. This undoes some of the 2002-07-25 change.
13022 Compatibility problem reported by Ralf S. Engelschall with
13023 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
13024
13025 2002-10-11 Akim Demaille <akim@epita.fr>

13042 * lib/lbitset.c: Likewise.
13043
13044 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13045 properly for vectors of objects. Do not assume that adding a
13046 header size to a multiple of a word size yields a value that is
13047 properly aligned for the whole union.
13048 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13049
13050 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,

13084 All instances of parameters of type enum bitset_opts are now of
13085 type enum_bitset_opts, to conform to the C Standard, and similarly
13086 for enum_bitset_type.
13087 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13088 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13089
13090 Do not use "struct bitset_struct" to mean different things in
13091 different modules. Not only is this confusing, it violates
13092 the C Standard, which requires that structure types in different
13093 modules must be compatible if one is to be passed to the other.
13094 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13095 All instances of "struct bitset_struct *" replaced with "bitset".
13096 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
13097 (union bitset_union, struct abitset_struct, struct ebitset_struct,
13098 struct lbitset_struct, struct bitset_stats_struct): New types.
13099 All uses of struct bitset_struct changed to union bitset_union,
13100 etc.
13101 * lib/abitset.c (struct abitset_struct, abitset,
13102 struct bitset_struct): Remove.
13103 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
13104 struct bitset_struct): Remove.
13105 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
13106 bitset_struct): Remove.
13107 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13108 Likewise.
13109
13110 Do not call a function of type T using a call that assumes the
13111 function is of a different type U. Standard C requires that a
13112 function must be called with a type that is compatible with its
13113 definition.
13114 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13115 New decls.

13122 decls.
13123 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
13124 (ebitset_vtable): Use them.
13125 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
13126 lbitset_xor): New functions.
13127 (lbitset_vtable): Use them.
13128
13129 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
13130 Declare.
13131
13132 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
13133 GCC warning.
13134 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
13135 Use offsetof, for simplicity.
13136
13137 2002-10-06 Paul Eggert <eggert@twinsun.com>
13138
13139 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13140 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13141 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13142 which was inadvertently undone by the 2002-09-30 patch.
13143 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
13144 the same width as int.
13145

13151
13152 * doc/bison.texinfo: Minor spelling, grammar, and white space
13153 fixes.
13154 (Symbols): Mention that any negative value returned from yylex
13155 signifies end-of-input. Warn about negative chars. Mention
13156 the portable Standard C character set.
13157
13158 The GNU coding standard says CFLAGS and YFLAGS are reserved
13159 for the installer to set.
13160 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
13161 * src/Makefile.am (AM_CFLAGS): Likewise.

13226 Use bitset_windex instead of unsigned int.
13227 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.

13243 BITSET_SIZE_MAX): New macros.
13244 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
13245 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
13246 to BITSET_WINDEX_MAX.
13247
13248 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13249 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13349
13350 * doc/bison.texinfo (Conditions): Make explicit that the GPL
13351 exception applies only to yacc.c. This is a modification of a

13401 functions are not portable. Do not assume size_t is the
13402 same width as int.
13403 (yypstates): Do not assume that ptrdiff_t is the same width
13404 as int, and similarly for yyposn and YYINDEX.
13405
13406 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

13444
13445 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
13446 PROTOTYPES to check for prototypes, and "defined __STDC__" to
13447 check for void *.
13448
13449 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
13450 size_t; the old version tried to do this but casted improperly.

13452 (bitset_test): Now returns int, not unsigned long.
13453
13454 * lib/bitset_stats.c: Include "gettext.h".
13455 (_): New macro.
13456 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
13457 name locals "index", as it generates unnecessary warnings on some
13458 hosts that have an "index" function.
13459
13460 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
13461 bitset_stats_read, bitset_stats_write): Wrap strings in _() if
13462 they need translation.
13463 * src/LR0.c (state_list_append, new_itemsets, get_state,
13464 append_states, generate_states): Likewise.

13476 * m4/malloc.m4, m4/realloc.m4: Sync with diffutils.
13477 * m4/mbstate_t.m4: Sync with fileutils.
13478 * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
13479
13480 * po/LINGUAS: Add pt_BR.
13481 * po/POTFILES.in: Add src/assoc.c, src/closure.c, src/gram.c,
13482 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
13483 lib/timevar.c.
13484 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
13485 manual recommends.
13486 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
13487
13488 * src/complain.c (strerror_r): Remove decl; not needed.
13489 (strerror): Use same pattern as ../lib/error.c.
13490

13494
13495 * src/main.c (main): Cast result of bindtextdomain and textdomain
13496 to void, to avoid a GCC warning when --disable-nls is in effect.
13497
13498 * src/scan-gram.l: Use strings rather than escapes when possible,
13499 to minimize the number of warnings from xgettext.
13500 (handle_action_dollar, handle_action_at): Don't use isdigit,
13501 as it mishandles negative chars and it may not work as expected
13502 outside the C locale.
13503
13504 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13505 this is a GCC extension and is not portable to other compilers.
13506
13507 * src/system.h (alloca): Use same pattern as ../lib/error.c.
13508 Do not include <ctype.h>; no longer needed.
13509 Do not include <malloc.h>; no longer needed (and generates
13510 warnings on OpenBSD 3.0).
13511
13512 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
13513 it's not portable.
13514
13515 * tests/regression.at: Do not use 'cc -c input.c -o input';
13516 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
13517
13518 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
13519 exit status as failure, not just exit status 1. Sun C exits
13520 with status 2 sometimes.
13521
13522 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
13523 Use it for the two large tests.
13524

13526
13527 * src/conflicts.c (conflicts_output): Don't output rules never
13528 reduced here, since anyway that computation doesn't work.

13530 (rule_useless_p, rule_never_reduced_p): New.

13534 (grammar_rules_never_reduced_report): New.
13535 * src/tables.c (action_row): Move the computation of rules never
13536 reduced to...
13537 (token_actions): here.
13538 * src/main.c (main): Make the parser before making the report, so
13539 that rules never reduced are computed.
13540 Call grammar_rules_never_reduced_report.
13541 * src/print.c (print_results): Report rules never reduced.
13542 * tests/conflicts.at, tests/reduce.at: Adjust.
13543
13544 2002-08-01 Akim Demaille <akim@epita.fr>
13545
13546 Instead of attaching lookaheads and duplicating the rules being
13547 reduced by a state, attach the lookaheads to the reductions.
13548
13549 * src/state.h (state_t): Remove the `lookaheads',
13550 `lookaheads_rule' member.
13551 (reductions_t): Add a `lookaheads' member.
13552 Use a regular array for the `rules'.

13563 (initialize_LA): this.
13564 (lalr_free): Adjust.
13565 * src/main.c (main): Don't free nullable and derives too early: it
13566 is used by --verbose.
13567 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
13568
13569 2002-08-01 Akim Demaille <akim@epita.fr>

13575 Adjust all dependencies.
13576 * src/nullable.c (set_nullable, free_nullable): Rename as...
13577 (nullable_compute, nullable_free): these.
13578 (rule_list_t): Store rule_t *, not rule_number_t.
13579 * src/state.c (state_rule_lookaheads_print): Directly compare rule
13580 pointers, instead of their numbers.
13581 * src/main.c (main): Call nullable_free, and derives_free earlier,
13582 as they were lo longer used.
13583
13584 2002-08-01 Akim Demaille <akim@epita.fr>
13585
13586 * lib/timevar.c (get_time): Include children time.
13587 * src/lalr.h (LA, LArule): Don't export them: used with the
13588 state_t.
13589 * src/lalr.c (LA, LArule): Static.
13590 * src/lalr.h, src/lalr.c (lalr_free): New.
13591 * src/main.c (main): Call it.
13592 * src/tables.c (pack_vector): Check whether loc is >= to the
13593 table_size, not >.
13594 (pack_tables): Don't free froms, tos, conflict_tos, and pos...
13595 (tables_generate): do it, since that's also it which allocates
13596 them.
13597 Don't free LA and LArule, main does.
13598
13599 2002-07-31 Akim Demaille <akim@epita.fr>
13600
13601 Separate parser tables computation and output.
13602

13635 * src/getargs.h, src/getargs.c: Support trace_time for
13636 --trace=time.
13637 * src/main.c (stage): Remove.
13638 (main): Replace `stage' invocations with timevar calls.
13639 * src/output.c: Insert pertinent timevar calls.
13640
13641 2002-07-31 Akim Demaille <akim@epita.fr>
13642
13643 Let --trace have arguments.
13644
13645 * src/getargs.h (enum trace_e): New.
13646 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
13647 (long_options, short_options): --trace/-T takes an optional
13648 argument.
13649 Change all the uses of trace_flag to reflect the new flags.
13650 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
13651
13652 Strengthen `stage' portability.
13653
13654 * m4/stage.m4 (BISON_PREREQ_STAGE): New.

13656 Don't check for malloc.h and sys/times.h.
13657 * src/system.h: Include them when appropriate.

13659 times and struct tms are available.
13660
13661 2002-07-30 Akim Demaille <akim@epita.fr>
13662

13664 expected token.
13665 * tests/actions.at (Printers and Destructors): Adjust.
13666 * tests/calc.at (Calculator $1): Adjust.
13667 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose
13668 error message, do not report the parser accepts the error token in
13669 that state.
13670
13671 2002-07-30 Akim Demaille <akim@epita.fr>

13683 Report rules which are never reduced by the parser: those hidden
13684 by conflicts.
13685
13686 * src/LR0.c (save_reductions): Don't make the final state too
13687 different: save its reduction (accept) instead of having a state
13688 without any action (no shift or goto, no reduce).
13689 Note: the final state is now a ``regular'' state, i.e., the
13690 parsers now contain `reduce 0' as default reduction.
13691 Nevertheless, since they decide to `accept' when yystate =
13692 final_state, they still will not reduce rule 0.
13693 * src/print.c (print_actions, print_reduction): Adjust.
13694 * src/output.c (action_row): Track reduced rules.
13695 (token_actions): Report rules never reduced.

13708

13722 (endtoken, accept): these.
13723 * src/reader.c (reader): Set endtoken's default tag to "$end".

13728 2002-07-29 Akim Demaille <akim@epita.fr>
13729
13730 * src/reduce.c (reduce_grammar): When the language is empty,
13731 complain about the start symbol, not the axiom.
13732 Use its location.
13733 * tests/reduce.at (Empty Language): New.
13734
13735 2002-07-26 Akim Demaille <akim@epita.fr>
13736
13737 * src/reader.h, src/reader.c (gram_error): ... can't get
13738 yycontrol without making too strong assumptions on the parser
13739 itself.
13740 * src/output.c (prepare_tokens): Use the real 0th value of
13741 token_translations instead of `0'.
13742 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
13743 visible here.
13744 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
13745 for the time being: %locations ought to provide it to yyerror.
13746
13747 2002-07-25 Akim Demaille <akim@epita.fr>
13748
13749 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

13758 * src/nullable.c, src/output.c, src/print.c, src/reader.c
13759 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
13760 Iterate from 0 to nrules.
13761 Use rule_number_as_item_number and item_number_as_rule_number.
13762 Adjust to `derive' now containing possibly 0.
13763 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):

14845
14846 * src/reader.c (parse_action): Don't store directly into the

14849 (grammar_current_rule_symbol_append)
14850 (grammar_current_rule_action_append): New, eved out from

14886 prologue.

14908 2002-06-10 Akim Demaille <akim@epita.fr>
14909
14910 Remove `%thong' support as it is undocumented, unused, duplicates
14911 `%token's job, and creates useless e-mail traffic with people who
14912 want to know what it is, why it is undocumented, unused, and
14913 duplicates `%token's job.
14914
14915 * src/reader.c (parse_thong_decl): Remove.

15104
15105 Kill GCC warnings.

15178 (prepare_rules): `i' is unsigned.
15179 `prhs', `rline', `r2' are unsigned int.

15184 to compute types instead of constant types.
15185 * tests/regression.at (Web2c Actions): Adjust.
15186
15187 2002-05-04 Akim Demaille <akim@epita.fr>

15283 * src/reader.c (copy_at, copy_dollarm parse_braces, parse_action)
15284 (parse_guard): Rename the formal argument `stack_offset' as
15285 `rule_length', which is more readable.
15286 Adjust callers.
15287 (copy_at, copy_dollar): Instead of outputting the hard coded
15288 values of $$, $n and so forth, output invocation to b4_lhs_value,
15289 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
15290 Note: this patch partially drops `semantic-parser' support: it
15291 always does `rule_length - n', where semantic parsers ought to
15292 always use `-n'.
15293 * data/bison.simple, data/bison.c++ (b4_lhs_value)
15294 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

15321
15322 * src/scan-skel.l: Postprocess quadrigraphs.
15323
15324 * src/reader.c (copy_character): New function, used to output
15325 single characters while replacing `[' and `]' with quadrigraphs, to
15326 avoid troubles with M4 quotes.

15337 between `!' and the command.
15338 Reported by Paul Eggert.
15339
15340 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
15341
15342 * tests/calc.at: Exercise prologue splitting.
15343
15344 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
15345 `b4_post_prologue' instead of `b4_prologue'.
15346
15347 * src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
15348 muscles.
15349 (output): Free pre_prologue_obstack and post_prologue_obstack.
15350 * src/files.h, src/files.c (attrs_obstack): Remove.
15351 (pre_prologue_obstack, post_prologue_obstack): New.
15352 * src/reader.c (copy_definition): Add a parameter to specify the
15353 obstack to fill, instead of using attrs_obstack unconditionally.
15354 (read_declarations): Pass pre_prologue_obstack to copy_definition if
15355 `%union' has not yet been seen, pass post_prologue_obstack otherwise.
15356
15357 2002-04-23 Paul Eggert <eggert@twinsun.com>
15358
15359 * data/bison.simple: Remove unnecessary commentary and white
15360 space differences from 1_29-branch.
15361 Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).
15362
15363 (union yyalloc, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYCOPY,
15364 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
15365 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial
15366 constructors or destructors.
15367
15368 (yyparse) [! defined YYSTACK_RELOCATE]: Do not relocate the stack.
15369
15370 2002-04-23 Akim Demaille <akim@epita.fr>

15395 * tests/regression.at (Web2c Actions): Adjust.
15396
15397 2002-04-22 Akim Demaille <akim@epita.fr>
15398
15399 * src/reader.c (token_translations_init): 256 is now the default
15400 value for the error token, i.e., it will be assigned another
15401 number if the user assigned 256 to one of her tokens.
15402 (reader): Don't force 256 to error.
15403 * doc/bison.texinfo (Symbols): Adjust.
15404 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
15405 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15406 etc. instead of 10, 20, 30 (which was used to `jump' over error

15408
15409 2002-04-22 Akim Demaille <akim@epita.fr>
15410
15411 Propagate more token_number_t.
15412
15413 * src/gram.h (token_number_as_item_number)
15414 (item_number_as_token_number): New.
15415 * src/output.c (GENERATE_OUTPUT_TABLE): New.
15416 Use it to create output_item_number_table and

15427 2002-04-19 Akim Demaille <akim@epita.fr>
15428
15429 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
15430 as Lex/Flex'.
15431 (Debugging): More details about enabling the debugging features.
15432 (Table of Symbols): Describe $$, $n, @$, and @n.
15433 Suggested by Tim Josling.
15434
15435 2002-04-19 Akim Demaille <akim@epita.fr>
15436
15437 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
15438
15439 2002-04-10 Akim Demaille <akim@epita.fr>

15444 2002-04-09 Akim Demaille <akim@epita.fr>
15445
15446 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15447 full stderr, and strip it according to the bison options, instead
15448 of composing the error message from different bits.
15449 This makes it easier to check for several error messages.
15450 Adjust all the invocations.
15451 Add an invocation exercising the error token.
15452 Add an invocation demonstrating a stupid error message.
15453 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.
15454 Adjust the tests.
15455 Error message are for stderr, not stdout.
15456

15459 * src/gram.h, src/gram.c (error_token_number): Remove, use
15460 errtoken->number.
15461 * src/reader.c (reader): Don't specify the user token number (2)
15462 for $undefined, as it uselessly prevents using it.
15463 * src/gram.h (token_number_t): Move to...
15464 * src/symtab.h: here.
15465 (state_t.number): Is a token_number_t.
15466 * src/print.c, src/reader.c: Use undeftoken->number instead of
15467 hard coded 2.
15468 (Even though this 2 is not the same as above: the number of the
15469 undeftoken remains being 2, it is its user token number which
15470 might not be 2).
15471 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15472 `user_token_number_max'.
15473 Output `undef_token_number'.
15474 * data/bison.simple, data/bison.c++: Use them.
15475 Be sure to map invalid yylex return values to
15476 `undef_token_number'. This saves us from gratuitous SEGV.
15477

15479 (Unresolved SR Conflicts): Adjust.
15480 * tests/regression.at (Web2c Actions): Adjust.

15485 Adding #line.
15486 Remove the duplicate `typedefs'.

15488 Use __ofile__.
15489 * data/bison.simple: Use __ofile__.
15490 * src/scan-skel.l: Handle __ofile__.

15493
15494 * src/gram.h (item_number_t): New, the type of item numbers in
15495 RITEM. Note that it must be able to code symbol numbers as
15496 positive number, and the negation of rule numbers as negative
15497 numbers.
15498 Adjust all dependencies (pretty many).
15499 * src/reduce.c (rule): Remove this `short *' pointer: use
15500 item_number_t.
15501 * src/system.h (MINSHORT, MAXSHORT): Remove.
15502 Include `limits.h'.
15503 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
15504 (shortcpy): Remove.
15505 (MAXTABLE): Move to...
15506 * src/output.c (MAXTABLE): here.
15507 (prepare_rules): Use output_int_table to output rhs.
15508 * data/bison.simple, data/bison.c++: Adjust.
15509 * tests/torture.at (Big triangle): Move the limit from 254 to
15510 500.
15511 * tests/regression.at (Web2c Actions): Ajust.
15512
15513 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15514 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15515 passes, but produces negative #line number, once fixed, GCC is
15516 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
15517 C), it passes.
15518 * src/state.h (state_h): Code input lines on ints, not shorts.
15519
15520 2002-04-08 Akim Demaille <akim@epita.fr>

15532 * src/output.c (output_table_data): Return the longest number.
15533 (prepare_tokens): Output `token_number_max').
15534 * data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
15535 New.
15536 Use them to define yy_token_number_type/TokenNumberType.

15539 253.
15540 * tests/regression.at (Web2c Actions): Adjust.
15541
15542 2002-04-07 Akim Demaille <akim@epita.fr>
15543

15645
15646 2002-04-07 Akim Demaille <akim@epita.fr>

15722 2002-04-07 Akim Demaille <akim@epita.fr>
15723
15724 * data/bison.c++, data/bison.simple: Don't output the current file

15968 2002-03-04 Akim Demaille <akim@epita.fr>
15969
15970 * lib/bitset-int.h, lib/bitset.c, lib/bitset.h, lib/bitsetv.c,
15971 * lib/bitsetv.h, lib/ebitset.c, lib/ebitset.h, lib/lbitset.c,
15972 * lib/lbitset.h, lib/sbitset.c, lib/sbitset.h: New.
15973 * src/closure.c (fderives): Be an array of bitsets.
15974
15975 2002-02-28 Robert Anisko <robert@lrde.epita.fr>
15976
15977 * data/bison.c++: Merge the two generated headers. Insert a copyright
15978 notice in each output file.
15979
15980 2002-02-28 Akim Demaille <akim@epita.fr>
15981
15982 * data/bison.c++: Copy the prologue of bison.simple to fetch
15983 useful M4 definitions, such as b4_header_guard.
15984
15985 2002-02-25 Akim Demaille <akim@epita.fr>
15986
15987 * src/getargs.c (version): Give the name of the authors, and use a
15988 translator friendly scheme for the bgr
15989 copyright notice.
15990
15991 2002-02-25 Akim Demaille <akim@epita.fr>
15992
15993 * src/output.c (header_output): Remove, now handled completely via
15994 M4.
15995
15996 2002-02-25 Akim Demaille <akim@epita.fr>
15997
15998 * m4/m4.m4: New, from CVS Autoconf.
15999 * configure.in: Invoke it.
16000 * src/output.c (output_skeleton): Use its result instead of the
16001 hard coded name.
16002
16003 2002-02-25 Akim Demaille <akim@epita.fr>
16004
16005 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
16006 Fileutils 4.1.5.
16007 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
16008 * src/output.c (output_skeleton): Use mkstemp to create a real
16009 temporary file.
16010 Move the filling of `skeleton' and its muscle to...
16011 (prepare): here.
16012 (output): Move the definition of the prologue muscle to...
16013 (prepare): here.
16014 * src/system.h (DEFAULT_TMPDIR): New.
16015
16016 2002-02-14 Paul Eggert <eggert@twinsun.com>
16017
16018 Remove the support for C++ namespace cleanliness; it was
16019 causing more problems than it was curing, since it didn't work
16020 properly on some nonstandard C++ compilers. This can wait
16021 for a proper C++ parser.
16022
16023 * NEWS: Document this.
16024 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
16025 of C++, as it's treated like C now.
16026 * src/bison.simple (YYSTD): Remove.
16027 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
16028 Treat C++ just like Standard C instead of trying to support
16029 namespace cleanliness.
16030
16031 2002-02-14 Akim Demaille <akim@epita.fr>
16032
16033 * tests/regression.at (else): Adjust to Andreas' change.
16034
16035 2002-02-14 Akim Demaille <akim@epita.fr>
16036
16037 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
16038
16039 2002-02-13 Andreas Schwab <schwab@suse.de>
16040
16041 * src/output.c (output_rule_data): Don't output NULL, it might
16042 not be defined yet.
16043
16044 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
16045
16046 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
16047 (Copyright notice): Update.
16048
16049 2002-02-11 Akim Demaille <akim@epita.fr>
16050
16051 * tests/regression.at (%nonassoc and eof): Don't include
16052 nonportable headers.
16053
16054 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
16055
16056 * data/bison.c++: Correct error recovery. Make the user able to
16057 initialize the starting location.
16058
16059 2002-02-07 Akim Demaille <akim@epita.fr>
16060
16061 * tests/input.at: New.
16062
16063 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16064
16065 * data/bison.c++: Replace some direct m4 expansions by constants. Be
16066 more consistent when naming methods and variables. Put preprocessor
16067 directives around tables only needed for debugging.
16068
16069 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16070
16071 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
16072 C++ parsers.
16073 (yy::b4_name::parse): Use print_.
16074
16075 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16076
16077 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
16078
16079 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16080
16081 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
16082 C++ parsers.
16083 (yy::b4_name::parse): Build verbose error messages, and use error_.
16084
16085 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16086
16087 * data/bison.c++: Fix m4 quoting in comments.
16088
16089 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16090
16091 * data/bison.c++: Adjust the parser code. Fix some muscles that were
16092 not expanded by m4.
16093
16094 2002-02-05 Akim Demaille <akim@epita.fr>
16095
16096 * data/bison.c++: Adjust to the M4 back end.
16097 More is certainly needed.
16098
16099 2002-02-05 Akim Demaille <akim@epita.fr>
16100
16101 Give a try to M4 as a back end.
16102
16103 * lib/readpipe.c: New, from wdiff.
16104 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
16105 BISON_HAIRY.
16106 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
16107 specific values. Now it is m4 that performs the lookup.
16108 * src/parse-skel.y: Remove.
16109 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
16110 * src/output.c (actions_output, guards_output)
16111 (token_definitions_output): No longer keeps track of the output
16112 line number, hence remove the second argument.
16113 (guards_output): Check against the guard member of a rule, not the
16114 action member.
16115 Adjust callers.
16116 (output_skeleton): Don't look for the skeleton location, let m4 do
16117 that.
16118 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
16119 file will be used.
16120 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
16121 (prepare): Given that for the time being changesyntax is not
16122 usable in M4, rename the muscles using `-' to `_'.
16123 Define `defines_flag', `output_parser_name' and `output_header_name'.
16124 * src/output.h (actions_output, guards_output)
16125 (token_definitions_output): Adjust prototypes.
16126 * src/scan-skel.l: Instead of scanning the skeletons, it now
16127 processes the output of m4: `__oline__' and `#output'.
16128 * data/bison.simple: Adjust to be used by M4(sugar).
16129 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
16130 to date.
16131 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
16132 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
16133 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
16134 shamelessly stolen from CVS Autoconf.
16135
16136 2002-02-05 Akim Demaille <akim@epita.fr>
16137
16138 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
16139 * configure.in: Check for the declarations of free and malloc.
16140 * src/muscle_tab.c: Adjust.
16141
16142 2002-02-05 Akim Demaille <akim@epita.fr>
16143
16144 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
16145 which have no values.
16146
16147 2002-02-05 Akim Demaille <akim@epita.fr>
16148
16149 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
16150 * data/: here.
16151
16152 2002-01-29 Paul Eggert <eggert@twinsun.com>
16153
16154 * src/bison.simple (YYSIZE_T): Do not define merely because
16155 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
16156 On some platforms, <alloca.h> does not declare YYSTD (size_t).
16157
16158 2002-01-27 Akim Demaille <akim@epita.fr>
16159
16160 Fix `%nonassoc and eof'.
16161
16162 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
16163 which were not properly copied! Replace
16164 memcpy (res->errs, src->errs, src->nerrs);
16165 with
16166 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
16167 !!!
16168 * tests/regression.at (%nonassoc and eof): Adjust to newest
16169 Autotest: `.' is not in the PATH.
16170
16171 2002-01-27 Akim Demaille <akim@epita.fr>
16172
16173 * tests/sets.at (AT_EXTRACT_SETS): New.
16174 (Nullable): Use it.
16175 (Firsts): New.
16176
16177 2002-01-26 Akim Demaille <akim@epita.fr>
16178
16179 * tests/actions.at, tests/calc.at, tests/headers.at,
16180 * tests/torture.at: Adjust to the newest Autotest which no longer
16181 forces `.' in the PATH.
16182
16183 2002-01-25 Akim Demaille <akim@epita.fr>
16184
16185 * tests/regression.at (%nonassoc and eof): New.
16186 Suggested by Robert Anisko.
16187
16188 2002-01-24 Akim Demaille <akim@epita.fr>
16189
16190 Bison dumps core when trying to complain about broken input files.
16191 Reported by Cris van Pelt.
16192
16193 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
16194 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
16195 into...
16196 (Invalid inputs): Strengthen: exercise parse_percent_token.
16197
16198 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
16199
16200 * src/Makefile.am: Add bison.c++.
16201 * src/bison.c++: New skeleton.
16202
16203 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
16204
16205 * po/it.po: New.
16206
16207 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
16208
16209 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
16210
16211 2002-01-20 Marc Autret <marc@gnu.org>
16212
16213 * src/files.c (compute_output_file_names): Fix
16214
16215 2002-01-20 Marc Autret <marc@gnu.org>
16216
16217 * tests/output.at: New test.
16218 * src/files.c (compute_base_names): Don't map extensions when
16219 the YACC flag is set, use defaults.
16220 Reported by Evgeny Stambulchik.
16221
16222 2002-01-20 Marc Autret <marc@gnu.org>
16223
16224 * src/system.h: Need to define __attribute__ away for non-GCC
16225 compilers as well (i.e., the vendor C compiler).
16226 Suggested by Albert Chin-A-Young.
16227
16228 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
16229
16230 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
16231 canonical definition.
16232 * src/system.h: Use the canonical definition for PARAMS (avoids
16233 a conflict with the macro from lib/hash.h).
16234
16235 2002-01-11 Akim Demaille <akim@epita.fr>
16236
16237 * configure.in: Use AC_FUNC_STRNLEN.
16238 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
16239
16240 2002-01-09 Akim Demaille <akim@epita.fr>
16241
16242 * src/files.c, src/files.h (output_infix): New.
16243 (tab_extension): Remove.
16244 (compute_base_names): Compute the former, drop the latter.
16245 * src/output.c (prepare): Insert the muscles `output-infix', and
16246 `output-suffix'.
16247 * src/parse-skel.y (string, string.1): New.
16248 (section.header): Use it.
16249 (section.yacc): Remove.
16250 (prefix): Remove too.
16251 * src/scan-skel.l: Adjust.
16252 * src/bison.simple, src/bison.hairy: Adjust.
16253
16254 2002-01-09 Akim Demaille <akim@epita.fr>
16255
16256 * configure.in (WERROR_CFLAGS): Compute it.
16257 * src/Makefile.am (CFLAGS): Pass it.
16258 * tests/atlocal.in (CFLAGS): Idem.
16259 * src/files.c: Fix a few warnings.
16260 (get_extension_index): Remove, unused.
16261
16262 2002-01-08 Akim Demaille <akim@epita.fr>
16263
16264 * src/getargs.c (AS_FILE_NAME): New.
16265 (getargs): Use it to convert DOSish file names.
16266 * src/files.c (base_name): Rename as full_base_name to avoid
16267 clashes with `base_name ()'.
16268 (filename_split): New.
16269 (compute_base_names): N-th rewrite, using filename_split.
16270
16271 2002-01-08 Akim Demaille <akim@epita.fr>
16272
16273 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16274 New, stolen from the Fileutils 4.1.
16275 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16276 * configure.in: Check for the presence of memrchr, and of its
16277 prototype.
16278
16279 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16280
16281 * lib/hash.h (__P): Added definition for this macro.
16282 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16283 BUILT_SOURCES, to ensure they are generated first.
16284 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16285 %error-verbose to allow bootstrapping with bison 1.30x.
16286
16287 2002-01-06 Akim Demaille <akim@epita.fr>
16288
16289 * src/reader.c (parse_braces): Don't fetch the next char, the
16290 convention is to fetch on entry.
16291 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16292 'switch' without a following semicolon.
16293 * tests/regression.at (braces parsing): New.
16294
16295 2002-01-06 Akim Demaille <akim@epita.fr>
16296
16297 Bison is dead wrong in its RR conflict reports.
16298
16299 * tests/torture.at (GNU Cim Grammar): New.
16300 * src/conflicts.c (count_rr_conflicts): Fix.
16301
16302 2002-01-06 Akim Demaille <akim@epita.fr>
16303
16304 Creating package.m4 from configure.ac causes too many problems.
16305
16306 * tests/Makefile.am (package.m4): Create it by hand,
16307 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16308
16309 2002-01-06 Akim Demaille <akim@epita.fr>
16310
16311 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16312 skeleton.h.
16313
16314 2002-01-04 Paul Eggert <eggert@twinsun.com>
16315
16316 * doc/bison.texinfo (Debugging):
16317 Remove YYSTDERR; it's no longer defined or used.
16318 Also, s/cstdio.h/cstdio/.
16319
16320 2002-01-03 Akim Demaille <akim@epita.fr>
16321
16322 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16323
16324 2002-01-03 Akim Demaille <akim@epita.fr>
16325
16326 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16327 tracing code to --trace, wait for a better --trace option, with
16328 args.
16329
16330 2002-01-03 Akim Demaille <akim@epita.fr>
16331
16332 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16333 The ISO C++ standard is extremely clear about it: stderr is
16334 considered a macro, not a regular symbol (see table 94 `Header
16335 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16336 Therefore std:: does not apply to it. It still does with fprintf.
16337 Also, s/cstdio.h/cstdio/.
16338
16339 2002-01-03 Akim Demaille <akim@epita.fr>
16340
16341 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16342 for non system headers.
16343
16344 2002-01-02 Akim Demaille <akim@epita.fr>
16345
16346 Equip the skeleton chain with location tracking, runtime trace,
16347 pure parser and scanner.
16348
16349 * src/parse-skel.y: Request a pure parser, locations, and prefix
16350 renaming.
16351 (%union): Having several members with the same type does not help
16352 type mismatches, simplify.
16353 (YYPRINT, yyprint): New.
16354 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16355 (skel_error): this.
16356 Handle locations.
16357 * src/scan-skel.l: Adjust to these changes.
16358 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16359 (LOCATION_PRINT, skel_control_t): New.
16360
16361 2001-12-30 Akim Demaille <akim@epita.fr>
16362
16363 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16364 replace `gb' with BLANKS.
16365 * src/scan-skel.l: Adjust.
16366
16367 2001-12-30 Akim Demaille <akim@epita.fr>
16368
16369 * src/system.h: We don't need nor want bcopy.
16370 Throw away MS-DOS crap: we don't need getpid.
16371 * configure.in: We don't need strndup. It was even causing
16372 problems: because Flex includes the headers *before* us,
16373 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16374 not visible.
16375 * lib/xstrndup.c: New.
16376 * src/scan-skel.l: Use it.
16377 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16378 * src/parse-skel.y: Use %directives instead of #defines.
16379
16380 2001-12-30 Akim Demaille <akim@epita.fr>
16381
16382 * src/skeleton.h: New.
16383 * src/output.c (output_parser, output_master_parser): Remove, dead
16384 code.
16385 * src/output.h (get_lines_number, actions_output, guards_output)
16386 (token_definitions_output): Prototype them.
16387 * src/parse-skel.y: Add the license notice.
16388 Include output.h and skeleton.h.
16389 (process_skeleton): Returns void, and takes a single parameter.
16390 * src/scan-skel.l: Add the license notice.
16391 Include skeleton.h.
16392 Don't use %option yylineno: it seems that then Flex imagines
16393 REJECT has been used, and therefore it won't reallocate its
16394 buffers (which makes no other sense to me than a bug). It results
16395 in warnings for `unused: yy_flex_realloc'.
16396
16397 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16398
16399 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16400 (MUSCLE_INSERT_PREFIX): ...to there.
16401 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16402 (MUSCLE_INSERT_PREFIX): Move from here...
16403
16404 * src/bison.hairy: Add a section directive. Put braces around muscle
16405 names. This parser skeleton is still broken, but Bison should not
16406 choke on a bad muscle 'syntax'.
16407 * src/bison.simple: Add a section directive. Put braces around muscle
16408 names.
16409
16410 * src/files.h (strsuffix, stringappend): Add declarations.
16411 (tab_extension): Add declaration.
16412 (short_base_name): Add declaration.
16413
16414 * src/files.c (strsuffix, stringappend): No longer static. These
16415 functions are used in the skeleton parser.
16416 (tab_extension): New.
16417 (compute_base_names): Use the computations done in this function
16418 to guess if the generated parsers should have '.tab' in their
16419 names.
16420 (short_base_name): No longer static.
16421
16422 * src/output.c (output_skeleton): New.
16423 (output): Disable call to output_master_parser, and give a try to
16424 a new skeleton handling system.
16425 (guards_output, actions_output): No longer static.
16426 (token_definitions_output, get_lines_number): No longer static.
16427
16428 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16429
16430 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16431 parse-skel.y.
16432
16433 * src/parse-skel.y: New file.
16434 * src/scan-skel.l: New file.
16435
16436 2001-12-29 Akim Demaille <akim@epita.fr>
16437
16438 %name-prefix is broken.
16439
16440 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16441 Adjust all dependencies.
16442 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16443 %name-prefix.
16444
16445 Renaming yylval but not yylloc is not consistent. Now we do.
16446
16447 * src/bison.simple: Prefix yylloc if used.
16448 * doc/bison.texinfo (Decl Summary): Document that.
16449
16450 2001-12-29 Akim Demaille <akim@epita.fr>
16451
16452 * doc/bison.texinfo: Promote `%long-directive' over
16453 `%long_directive'.
16454 Remove all references to fixed-output-files, yacc is enough.
16455
16456 2001-12-29 Akim Demaille <akim@epita.fr>
16457
16458 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16459 user prologue. These are defaults.
16460 * tests/actions.at (Mid-rule actions): Make sure the user can
16461 define YYDEBUG and YYERROR_VERBOSE.
16462
16463 2001-12-29 Akim Demaille <akim@epita.fr>
16464
16465 * src/output.c (header_output): Don't forget to export YYLTYPE and
16466 yylloc.
16467 * tests/headers.at (export YYLTYPE): New, make sure it does.
16468 * tests/regression.at (%union and --defines, Invalid CPP headers):
16469 Move to...
16470 * tests/headers.at: here.
16471
16472 2001-12-29 Akim Demaille <akim@epita.fr>
16473
16474 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16475
16476 2001-12-29 Akim Demaille <akim@epita.fr>
16477
16478 * tests/actions.at (Mid-rule actions): Output on a single line
16479 instead of several.
16480
16481 2001-12-29 Akim Demaille <akim@epita.fr>
16482
16483 * doc/bison.texinfo: Formatting changes.
16484
16485 2001-12-29 Akim Demaille <akim@epita.fr>
16486
16487 Don't store the token defs in a muscle, just be ready to output it
16488 on command. Now possible via `symbols'. Fixes a memory leak.
16489
16490 * src/output.c (token_definitions_output): New.
16491 (output_parser, header_output): Use it.
16492 * src/reader.c (symbols_save): Remove.
16493
16494 2001-12-29 Akim Demaille <akim@epita.fr>
16495
16496 * src/bison.simple: Do not provide a default for YYSTYPE and
16497 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16498 default.
16499
16500 2001-12-29 Akim Demaille <akim@epita.fr>
16501
16502 Mid-rule actions are simply... ignored!
16503
16504 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16505 the empty-rule associated to the dummy symbol, not to the host
16506 rule.
16507 * tests/actions.at (Mid-rule actions): New.
16508
16509 2001-12-29 Akim Demaille <akim@epita.fr>
16510
16511 Memory leak.
16512
16513 * src/reader.c (reader): Free grammar.
16514
16515 2001-12-29 Akim Demaille <akim@epita.fr>
16516
16517 Memory leak.
16518
16519 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16520 since it allocates it for each state, although only one is needed.
16521 (allocate_storage): Do it here.
16522
16523 2001-12-29 Akim Demaille <akim@epita.fr>
16524
16525 * src/options.h, src/options.c (create_long_option_table): Rename
16526 as...
16527 (long_option_table_new): this, with a clearer prototype.
16528 (percent_table): Remove, unused,
16529 * src/getargs.c (getargs): Adjust.
16530
16531 2001-12-29 Akim Demaille <akim@epita.fr>
16532
16533 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16534 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16535 as states.
16536
16537 2001-12-29 Akim Demaille <akim@epita.fr>
16538
16539 * src/lalr.c (build_relations): Rename `states' as `states1'.
16540 Sorry, I don't understand exactly what it is, no better name...
16541
16542 2001-12-29 Akim Demaille <akim@epita.fr>
16543
16544 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16545 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16546 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16547 as rules.
16548
16549 2001-12-29 Akim Demaille <akim@epita.fr>
16550
16551 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16552 ago.
16553
16554 2001-12-29 Akim Demaille <akim@epita.fr>
16555
16556 * src/reader.c, src/reader.h (user_toknums): Remove.
16557 Adjust all users to use symbols[i]->user_token_number.
16558
16559 2001-12-29 Akim Demaille <akim@epita.fr>
16560
16561 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16562 Adjust all users to use symbols[i]->prec or ->assoc.
16563
16564 2001-12-29 Akim Demaille <akim@epita.fr>
16565
16566 * src/reader.c, src/reader.h (tags): Remove.
16567 Adjust all users to use symbols[i]->tag.
16568
16569 2001-12-29 Akim Demaille <akim@epita.fr>
16570
16571 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16572 and rule_table.
16573 * src/reader.c (packsymbols): Fill this table.
16574 Drop sprec.
16575 * src/conflicts.c (resolve_sr_conflict): Adjust.
16576 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16577 single table.
16578 Use symbols[i]->tag instead of tags[i].
16579
16580 2001-12-29 Akim Demaille <akim@epita.fr>
16581
16582 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16583 In addition, put a comment in there, to replace...
16584 * tests/regression.at (%union and C comments): Remove.
16585
16586 2001-12-29 Akim Demaille <akim@epita.fr>
16587
16588 * tests/regression.at (Web2c Actions): Blindly move the actual
16589 output as expected output. The contents *seem* right to me, but I
16590 can't pretend reading perfectly parser tables... Nonetheless, all
16591 the other tests pass correctly, the table look OK, even though the
16592 presence of `$axiom' is to be noted: AFAICS it is useless (but
16593 harmless).
16594
16595 2001-12-29 Akim Demaille <akim@epita.fr>
16596
16597 * src/reader.c (readgram): Don't add the rule 0 if there were no
16598 rules read. In other words, add it _after_ having performed
16599 grammar sanity checks.
16600 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16601
16602 2001-12-29 Akim Demaille <akim@epita.fr>
16603
16604 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16605 visible, and some states have now a different number.
16606
16607 2001-12-29 Akim Demaille <akim@epita.fr>
16608
16609 * src/reader.c (readgram): Bind the initial rule's lineno to that
16610 of the first rule.
16611 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16612 (Solved SR Conflicts): Adjust rule 0's line number.
16613
16614 2001-12-29 Akim Demaille <akim@epita.fr>
16615
16616 Fix the `GAWK Grammar' failure.
16617
16618 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16619 the reductions of the first state which was mistakenly confused
16620 with the final state because precisely final_state was initialized
16621 to 0.
16622 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16623 now noticed by Bison.
16624 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16625 have a reduction on $default.
16626
16627 2001-12-29 Akim Demaille <akim@epita.fr>
16628
16629 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16630 rule line numbers.
16631 * src/closure.c (print_closure): Likewise.
16632 * src/derives.c (print_derives): Likewise.
16633 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16634 now.
16635
16636 2001-12-29 Akim Demaille <akim@epita.fr>
16637
16638 * src/lalr.c (lookaheads_print): New.
16639 (lalr): Call it when --trace-flag.
16640 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16641 are dumped.
16642
16643 2001-12-29 Akim Demaille <akim@epita.fr>
16644
16645 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
16646 when walking through ritem, even via rule->rhs.
16647 * src/reduce.c (dump_grammar, useful_production, reduce_output)
16648 (useful_production, useless_nonterminals): Likewise.
16649 (reduce_grammar_tables): Likewise, plus update nritems.
16650 * src/nullable.c (set_nullable): Likewise.
16651 * src/lalr.c (build_relations): Likewise.
16652 * tests/sets.at (Nullable): Adjust.
16653 Fortunately, now, the $axiom is no longer nullable.
16654
16655 2001-12-29 Akim Demaille <akim@epita.fr>
16656
16657 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
16658 the 0-sentinel.
16659 * src/gram.c (ritem_longest_rhs): Likewise.
16660 * src/reduce.c (nonterminals_reduce): Likewise.
16661 * src/print_graph.c (print_graph): Likewise.
16662 * src/output.c (output_rule_data): Likewise.
16663 * src/nullable.c (set_nullable): Likewise.
16664
16665 2001-12-29 Akim Demaille <akim@epita.fr>
16666
16667 * src/output.c: Comment changes.
16668
16669 2001-12-27 Paul Eggert <eggert@twinsun.com>
16670
16671 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
16672 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
16673 Sparc, as they were causing more porting problems than the
16674 (minor) performance improvement was worth.
16675
16676 Also, catch up with 1.31's YYSTD.
16677
16678 2001-12-27 Akim Demaille <akim@epita.fr>
16679
16680 * src/output.c (output_gram): Rely on nritems, not the
16681 0-sentinel. See below.
16682 Use -1 as separator, not 0.
16683 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
16684 Rely on -1 as separator in yyrhs, instead of 0.
16685 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
16686 twice `Now at end of input', therefore there are two lines less to
16687 expect.
16688
16689 2001-12-27 Akim Demaille <akim@epita.fr>
16690
16691 * tests/regression.at (Unresolved SR Conflicts):
16692 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
16693 below.
16694
16695 2001-12-27 Akim Demaille <akim@epita.fr>
16696
16697 * src/LR0.c (new_state): Recognize the final state by the fact it
16698 is reached by eoftoken.
16699 (insert_start_shifting_state, insert_eof_shifting_state)
16700 (insert_accepting_state, augment_automaton): Remove, since now
16701 these states are automatically computed from the initial state.
16702 (generate_states): Adjust.
16703 * src/print.c: When reporting a rule number to the user, substract
16704 1, so that the axiom rule is rule 0, and the first user rule is 1.
16705 * src/reduce.c: Likewise.
16706 * src/print_graph.c (print_core): For the time being, just as for
16707 the report, depend upon --trace-flags to dump the full set of
16708 items.
16709 * src/reader.c (readgram): Once the grammar read, insert the rule
16710 0: `$axiom: START-SYMBOL $'.
16711 * tests/set.at: Adjust: rule 0 is now displayed, and since the
16712 number of the states has changed (the final state is no longer
16713 necessarily the last), catch up.
16714
16715 2001-12-27 Akim Demaille <akim@epita.fr>
16716
16717 Try to make the use of the eoftoken valid. Given that its value
16718 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
16719 is used instead of > 0 where appropriate, (ii), depend upon nritems
16720 instead of the 0-sentinel.
16721
16722 * src/gram.h, src/gram.c (nritems): New.
16723 Expected to be duplication of nitems, but for the time being...
16724 * src/reader.c (packgram): Assert nritems and nitems are equal.
16725 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
16726 * src/closure.c (print_closure, print_fderives): Likewise.
16727 * src/gram.c (ritem_print): Likewise.
16728 * src/print.c (print_core, print_grammar): Likewise.
16729 * src/print_graph.c: Likewise.
16730
16731 2001-12-27 Akim Demaille <akim@epita.fr>
16732
16733 * src/main.c (main): If there are complains after grammar
16734 reductions, then output the report anyway if requested, then die.
16735 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
16736 * src/reader.c (eoftoken): New.
16737 (parse_token_decl): If the token being defined has value `0', it
16738 is the eoftoken.
16739 (packsymbols): No longer hack `tags' to insert `$' by hand.
16740 Be sure to preserve the value of the eoftoken.
16741 (reader): Make sure eoftoken is defined.
16742 Initialize nsyms to 0: now eoftoken is created just like the others.
16743 * src/print.c (print_grammar): Don't special case the eof token.
16744 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
16745 lie anyway, albeit pleasant.
16746 * tests/calc.at: Exercise error messages with eoftoken.
16747 Change the grammar so that empty input is invalid.
16748 Adjust expectations.
16749 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
16750
16751 2001-12-27 Akim Demaille <akim@epita.fr>
16752
16753 * configure.in: Check the protos of strchr ans strspn.
16754 Replace strchr if needed.
16755 * src/system.h: Provide the protos of strchr, strspn and memchr if
16756 missing.
16757 * lib/strchr.c: New.
16758 * src/reader.c (symbols_save): Use strchr.
16759
16760 2001-12-27 Akim Demaille <akim@epita.fr>
16761
16762 * src/print.c, src/print_graph.c (escape): New.
16763 Use it to quote the TAGS outputs.
16764 * src/print_graph.c (print_state): Now errors are in red, and
16765 reductions in green.
16766 Prefer high to wide: output the state number on a line of its own.
16767
16768 2001-12-27 Akim Demaille <akim@epita.fr>
16769
16770 * src/state.h, src/state.c (reductions_new): New.
16771 * src/LR0.c (set_state_table): Let all the states have a
16772 `reductions', even if reduced to 0.
16773 (save_reductions): Adjust.
16774 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
16775 * src/print.c (print_reductions, print_actions): Adjust.

16777
16778 2001-12-27 Akim Demaille <akim@epita.fr>
16779

16784 * src/output.c (output_actions, action_row): Adjust.
16785 * src/conflicts.c (resolve_sr_conflict): Adjust.
16786
16787 2001-12-27 Akim Demaille <akim@epita.fr>
16788
16789 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
16790
16791 2001-12-27 Akim Demaille <akim@epita.fr>
16792
16793 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
16794 * src/print.c: here.
16795 (lookaheadset, shiftset): New, used as additional storage by
16796 print_reductions.
16797 (print_results): Adjust.
16798 (print_shifts, print_gotos, print_errs): New, extracted from...
16799 (print_actions): here.
16800 * src/print_graph.c (print_actions): Remove dead code.
16801
16802 2001-12-27 Akim Demaille <akim@epita.fr>
16803
16804 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
16805 `$n' and `@n'.
16806
16807 2001-12-27 Akim Demaille <akim@epita.fr>
16808
16809 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
16810 (build_relations): Adjust.
16811
16812 2001-12-27 Akim Demaille <akim@epita.fr>
16813
16814 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
16815 duplication.
16816
16817 2001-12-27 Akim Demaille <akim@epita.fr>
16818
16819 * src/reader.c (packgram): Catch nitems overflows.
16820
16821 2001-12-27 Akim Demaille <akim@epita.fr>
16822
16823 * src/files.c, src/files.h (guard_obstack): Remove.
16824 * src/output.c (output): Adjust.
16825 * src/reader.c (parse_braces): New, factoring...
16826 (copy_action, copy_guard): these two which are renamed as...
16827 (parse_action, parse_guard): these.
16828 As a voluntary consequence, using braces around guards is now
16829 mandatory.
16830
16831 2001-12-27 Akim Demaille <akim@epita.fr>
16832
16833 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
16834 * src/reader.c (symbol_list): `guard' and `guard_line' are new
16835 members.
16836 (symbol_list_new): Adjust.
16837 (copy_action): action_line is the first line, not the last.
16838 (copy_guard): Just as for actions, store the `action' only, not
16839 the switch/case/break flesh.
16840 Don't parse the user action that might follow the guard, let...
16841 (readgram): do it, i.e., now, there can be an action after a
16842 guard.
16843 In other words the guard is just explicitly optional.
16844 (packgram): Adjust.
16845 * src/output.c (guards_output): New.
16846 (output_parser): Call it when needed.
16847 (output): Also free the guard and attrs obstacks.
16848 * src/files.c, src/files.h (obstack_save): Remove.
16849 (output_files): Remove.
16850 As a result, if one needs the former `.act' file, using an
16851 appropriate skeleton which requires actions and guards is now
16852 required.
16853 * src/main.c (main): Adjust.
16854 * tests/semantic.at: New.
16855 * tests/regression.at: Use `input.y' as input file name.
16856 Avoid 8+3 problems by requiring input.c when the test needs the
16857 parser.
16858
16859 2001-12-27 Akim Demaille <akim@epita.fr>
16860
16861 * src/reader.c (symbol_list_new): Be sure to initialize all the
16862 fields.
16863
16864 2001-12-27 Akim Demaille <akim@epita.fr>
16865
16866 All the hacks using a final pseudo state are now useless.
16867
16868 * src/LR0.c (set_state_table): state_table holds exactly nstates.
16869 * src/lalr.c (nLA): New.
16870 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
16871 instead of lookaheadsp from the pseudo state (nstate + 1).
16872
16873 2001-12-27 Akim Demaille <akim@epita.fr>
16874
16875 * src/output.c (action_row, token_actions): Use a state_t instead
16876 of a integer, and nlookaheads instead of the following state's
16877 lookaheadsp.
16878
16879 2001-12-27 Akim Demaille <akim@epita.fr>
16880
16881 * src/conflicts.c (log_resolution, flush_shift)
16882 (resolve_sr_conflict, set_conflicts, solve_conflicts)
16883 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
16884 (conflicts_print, print_reductions): Use a state_t instead of an
16885 integer when referring to a state.
16886 As much as possible, depend upon nlookaheads, instead of the
16887 `lookaheadsp' member of the following state (since lookaheads of
16888 successive states are successive, the difference between state n + 1
16889 and n served as the number of lookaheads for state n).
16890 * src/lalr.c (add_lookback_edge): Likewise.
16891 * src/print.c (print_core, print_actions, print_state)
16892 (print_results): Likewise.
16893 * src/print_graph.c (print_core, print_actions, print_state)
16894 (print_graph): Likewise.
16895 * src/conflicts.h: Adjust.
16896
16897 2001-12-27 Akim Demaille <akim@epita.fr>
16898
16899 * src/bison.hairy: Formatting/comment changes.
16900 ANSIfy.
16901 Remove `register' indications.
16902 Add plenty of `static'.
16903
16904 2001-12-27 Akim Demaille <akim@epita.fr>
16905
16906 * src/output.c (prepare): Drop the muscle `ntbase' which
16907 duplicates ntokens.
16908 * src/bison.simple: Formatting/comment changes.
16909 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
16910 is an undocumented synonym.
16911
16912 2001-12-22 Akim Demaille <akim@epita.fr>
16913
16914 * src/output.c (output_table_data): Change the prototype to use
16915 `int' for array ranges: some invocations do pass an int, not a
16916 short.
16917 Reported by Wayne Green.
16918
16919 2001-12-22 Akim Demaille <akim@epita.fr>
16920
16921 Some actions of web2c.y are improperly triggered.
16922 Reported by Mike Castle.
16923
16924 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
16925 * tests/regression.at (Web2c): Rename as...
16926 (Web2c Report): this.
16927 (Web2c Actions): New.
16928
16929 2001-12-22 Akim Demaille <akim@epita.fr>
16930
16931 Reductions in web2c.y are improperly reported.
16932 Reported by Mike Castle.
16933
16934 * src/conflicts.c (print_reductions): Fix.
16935 * tests/regression.at (Web2c): New.
16936
16937 2001-12-18 Akim Demaille <akim@epita.fr>
16938
16939 Some host fail on `assert (!"foo")', which expands to
16940 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
16941 Reported by Nelson Beebee.
16942
16943 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
16944 `#define it_succeeded 0' and `assert (it_succeeded)'.
16945
16946 2001-12-17 Marc Autret <autret_m@epita.fr>
16947
16948 * src/bison.simple: Don't hard code the skeleton line and filename.
16949 * src/output.c (output_parser): Rename 'line' as 'output_line'.
16950 New line counter 'skeleton_line' (skeleton-line muscle).
16951
16952 2001-12-17 Paul Eggert <eggert@twinsun.com>
16953
16954 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
16955 YYDEBUG must be defined to a nonzero value.
16956
16957 * src/bison.simple (yytname): Do not assume that the user defines
16958 YYDEBUG to a properly parenthesized expression.
16959
16960 2001-12-17 Akim Demaille <akim@epita.fr>
16961
16962 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
16963 nlookaheads is a new member.
16964 Adjust all users.
16965 * src/lalr.h (nlookaheads): Remove this orphan declaration.
16966 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
16967 state.
16968
16969 2001-12-17 Akim Demaille <akim@epita.fr>
16970
16971 * src/files.h, src/files.c (open_files, close_files): Remove.
16972 * src/main.c (main): Don't open/close files, nor invoke lex_free,
16973 let...
16974 * src/reader.c (reader): Do it.
16975
16976 2001-12-17 Akim Demaille <akim@epita.fr>
16977
16978 * src/conflicts.c (print_reductions): Formatting changes.
16979
16980 2001-12-17 Akim Demaille <akim@epita.fr>
16981
16982 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
16983 (flush_reduce): New.
16984 (resolve_sr_conflict): Adjust.
16985
16986 2001-12-17 Akim Demaille <akim@epita.fr>
16987
16988 * src/output.c (output_obstack): Be static and rename as...
16989 (format_obstack): this, to avoid any confusion with files.c's
16990 output_obstack.
16991 * src/reader.h (muscle_obstack): Move to...
16992 * src/output.h: here, since it's defined in output.c.
16993
16994 2001-12-17 Akim Demaille <akim@epita.fr>
16995
16996 * src/output.c (action_row, save_column, default_goto)
16997 (sort_actions, matching_state, pack_vector): Better variable
16998 locality.
16999
17000 2001-12-17 Akim Demaille <akim@epita.fr>
17001
17002 * src/output.c: Various formatting changes.
17003
17004 2001-12-17 Akim Demaille <akim@epita.fr>
17005
17006 * src/files.c (output_files): Free the output_obstack.
17007 * src/main.c (main): Call print and print_graph conditionally.
17008 * src/print.c (print): Work unconditionally.
17009 * src/print_graph.c (print_graph): Work unconditionally.
17010 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17011
17012 2001-12-16 Marc Autret <autret_m@epita.fr>
17013
17014 * src/output.c (actions_output): Fix. When we use %no-lines,
17015 there is one less line per action.
17016
17017 2001-12-16 Marc Autret <autret_m@epita.fr>
17018
17019 * src/bison.simple: Remove a useless #line directive.
17020 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17021 * src/output.c (get_lines_number): New.
17022 (output_parser): Adjust, now takes care about the lines of a
17023 output muscles.
17024 Fix line numbering.
17025 (actions_output): Computes the number of lines taken by actions.
17026 (output_master_parser): Insert new skeleton which is the name of
17027 the output parser file name.
17028
17029 2001-12-15 Marc Autret <autret_m@epita.fr>
17030
17031 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17032
17033 2001-12-15 Marc Autret <autret_m@epita.fr>
17034
17035 * src/output.c (output_gram): Keep track of the hairy one.
17036
17037 2001-12-15 Akim Demaille <akim@epita.fr>
17038
17039 Make `make distcheck' work.
17040
17041 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17042 system.h which uses libgettext.h.
17043
17044 2001-12-15 Akim Demaille <akim@epita.fr>
17045
17046 * src/nullable.c (set_nullable): Useless rules must be skipped,
17047 otherwise, since we range over their symbols, we might look at a
17048 nonterminal which no longer ``exists'', i.e., it is not counted in
17049 `nvars', hence we overflow our arrays.
17050
17051 2001-12-15 Akim Demaille <akim@epita.fr>
17052
17053 The header can also be produced directly, without any obstack!
17054 Yahoo!
17055
17056 * src/files.c, src/files.h (defines_obstack): Remove.
17057 (compute_header_macro): Global.
17058 (defines_obstack_save): Remove.
17059 * src/reader.c (parse_union_decl): No longer output to
17060 defines_obstack: its content can be found in the `stype' muscle
17061 anyway.
17062 (output_token_translations): Merge into...
17063 (symbols_output): this.
17064 Rename as...
17065 (symbols_save): this.
17066 (reader): Adjust.
17067 * src/output.c (header_output): New.
17068 (output): Call it.
17069
17070 2001-12-15 Akim Demaille <akim@epita.fr>
17071
17072 * src/reader.c (parse_union_decl): Instead of handling two obstack
17073 simultaneously, use one to define the `stype' muscle, and use the
17074 value of the latter to fill defines_obstack.
17075 (copy_comment): Remove.
17076 (copy_comment2): Work for a single obstack.
17077 Rename as...
17078 (copy_comment): this.
17079
17080 2001-12-15 Akim Demaille <akim@epita.fr>
17081
17082 * src/lex.c, src/lex.h (xgetc): No longer static.
17083 * src/reader.c (parse_union_decl): Revamp.
17084
17085 2001-12-15 Akim Demaille <akim@epita.fr>
17086
17087 Still making progress in separating Bison into (i) input, (ii)
17088 process, (iii) output: now we can directly output the parser file
17089 without using table_obstack at all.
17090
17091 * src/files.c, src/files.h (table_obstack): Bye bye.
17092 (parser_file_name): New.
17093 * src/files.c (compute_output_file_names): Compute it.
17094 * src/output.c (actions_output, output_parser)
17095 (output_master_parser): To a file instead of an obstack.
17096
17097 2001-12-15 Akim Demaille <akim@epita.fr>
17098
17099 Attach actions to rules, instead of pre-outputting them to
17100 actions_obstack.
17101
17102 * src/gram.h (rule_t): action and action_line are new members.
17103 * src/reader.c (symbol_list): Likewise.
17104 (copy_action): Save the actions within the rule.
17105 (packgram): Save them in rule_table.
17106 * src/output.c (actions_output): New.
17107 (output_parser): Use it on `%%actions'.
17108 (output_rule_data): Don't free rule_table.
17109 (output): Do it.
17110 (prepare): Don't save the `action' muscle.
17111 * src/bison.simple: s/%%action/%%actions/.
17112
17113 2001-12-15 Akim Demaille <akim@epita.fr>
17114
17115 * src/reader.c (copy_action): When --yacc, don't append a `;'
17116 to the user action: let it fail if lacking.
17117 Suggested by Arnold Robbins and Tom Tromey.
17118
17119 2001-12-14 Akim Demaille <akim@epita.fr>
17120
17121 * src/lex.c (literalchar): Simply return the char you decoded, non
17122 longer mess around with obstacks and int pointers.
17123 Adjust all callers.
17124
17125 2001-12-14 Akim Demaille <akim@epita.fr>
17126
17127 * src/lex.c (literalchar): Don't escape the special characters,
17128 just decode them, and keep them as char (before, eol was output as
17129 the 2 char string `\n' etc.).
17130 * src/output.c (output_rule_data): Use quotearg to output the
17131 token strings.
17132
17133 2001-12-13 Paul Eggert <eggert@twinsun.com>
17134
17135 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17136 Do not infringe on the global user namespace when using C++.
17137 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17138 All uses of `fprintf' and `stderr' changed.
17139
17140 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17141
17142 2001-12-13 Akim Demaille <akim@epita.fr>
17143
17144 The computation of nullable is broken: it doesn't handle empty
17145 RHS's properly.
17146
17147 * tests/torture.at (GNU AWK Grammar): New.
17148 * tests/sets.at (Nullable): New.
17149 * src/nullable.c (set_nullable): Instead of blindly looping over
17150 `ritems', loop over the rules, and then over their rhs's.
17151
17152 Work around Autotest bugs.
17153
17154 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17155 frame, because Autotest understand lines starting with a `+' as
17156 traces from the shell. Then, they are not processed properly.
17157 Admittedly an Autotest bug, but we don't have time to wait for
17158 Autotest to catch up.
17159 * tests/regression.at (Broken Closure): Adjust to the new table
17160 frames.
17161 Move to...
17162 * tests/sets.at: here.
17163
17164 2001-12-13 Akim Demaille <akim@epita.fr>
17165
17166 * src/closure.c (closure): Use nrules instead of playing tricks
17167 with BITS_PER_WORD.
17168
17169 2001-12-13 Akim Demaille <akim@epita.fr>
17170
17171 * src/print.c (print_actions): Output the handling of `$' as the
17172 traces do: shifting the token EOF. Before EOF was treated as a
17173 nonterminal.
17174 * tests/regression.at: Adjust some tests.
17175 * src/print_graph.c (print_core): Complete the set of items via
17176 closure. The next-to-final and final states are still unsatisfying,
17177 but that's to be addressed elsewhere.
17178 No longer output the rule numbers, but do output the state number.
17179 A single loop for the shifts + gotos is enough, but picked a
17180 distinct color for each.
17181 (print_graph): Initialize and finalize closure.
17182
17183 2001-12-13 Akim Demaille <akim@epita.fr>
17184
17185 * src/reader.c (readgram): Remove dead code, an strip useless
17186 braces.
17187 (get_type): Remove, unused.
17188
17189 2001-12-12 Akim Demaille <akim@epita.fr>
17190
17191 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17192 on that of lib/error.c.
17193
17194 2001-12-12 Akim Demaille <akim@epita.fr>
17195
17196 Some hosts don't like `/' in includes.
17197
17198 * src/system.h: Include libgettext.h without qualifying the path.
17199 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
17200 $(top_srcdir).
17201
17202 2001-12-11 Marc Autret <autret_m@epita.fr>
17203
17204 * src/output.c (output_parser): Remove useless muscle.
17205
17206 2001-12-11 Marc Autret <autret_m@epita.fr>
17207
17208 * src/bison.simple: Remove #line just before %%epilogue. It
17209 is now handled in ...
17210 * src/reader.c (read_additionnal_code): Add the output of a
17211 #line for the epilogue.
17212
17213 2001-12-10 Marc Autret <autret_m@epita.fr>
17214
17215 * src/reader.c (copy_definition): Re-use CPP-outed code which
17216 replace precedent remove.
17217 * src/bison.simple: Remove #line before %%prologue because
17218 %%input-line is wrong at this time.
17219
17220 2001-12-10 Marc Autret <autret_m@epita.fr>
17221
17222 * src/reader.c (symbols_output): Clean up.
17223 * src/output.c (output_gram, output): Clean up.
17224
17225 2001-12-10 Akim Demaille <akim@epita.fr>
17226
17227 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17228 * src/LR0.c (set_state_table): here.
17229 * src/lalr.c (lalr): Call it.
17230
17231 2001-12-10 Akim Demaille <akim@epita.fr>
17232
17233 * src/state.h (shifts): Remove the `number' member: shifts are
17234 attached to state, hence no longer need to be labelled with a
17235 state number.
17236
17237 2001-12-10 Akim Demaille <akim@epita.fr>
17238
17239 Now that states have a complete set of members, the linked list of
17240 shifts is useless: just fill directly the state's shifts member.
17241
17242 * src/state.h (shifts): Remove the `next' member.
17243 * src/LR0.c (first_state, last_state): Remove.
17244 Adjust the callers.
17245 (augment_automaton): Don't look for the shifts that must be added
17246 a shift on EOF: it is those of the state we looked for! But now,
17247 since shifts are attached, it is no longer needed to looking
17248 merely by its id: its number.
17249
17250 2001-12-10 Akim Demaille <akim@epita.fr>
17251
17252 * src/LR0.c (augment_automaton): Better variable locality.
17253 Remove an impossible branch: if there is a state corresponding to
17254 the start symbol being shifted, then there is shift for the start
17255 symbol from the initial state.
17256
17257 2001-12-10 Akim Demaille <akim@epita.fr>
17258
17259 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17260 only when appropriate: when insert_start_shifting_state' is not
17261 invoked.
17262 * tests/regression.at (Rule Line Numbers): Adjust.
17263
17264 2001-12-10 Akim Demaille <akim@epita.fr>
17265
17266 * src/LR0.c (augment_automaton): Now that all states have shifts,
17267 merge the two cases addition shifts to the initial state.
17268
17269 2001-12-10 Akim Demaille <akim@epita.fr>
17270
17271 * src/lalr.c (set_state_table): Move to...
17272 * src/LR0.c: here.
17273 * src/lalr.c (lalr): Don't call it...
17274 * src/LR0.c (generate_states): do it.
17275 * src/LR0.h (first_state): Remove, only the table is used.
17276
17277 2001-12-10 Akim Demaille <akim@epita.fr>
17278
17279 * src/LR0.h (first_shift, first_reduction): Remove.
17280 * src/lalr.c: Don't use first_shift: find shifts through the
17281 states.
17282
17283 2001-12-10 Akim Demaille <akim@epita.fr>
17284
17285 * src/LR0.c: Attach shifts to states as soon as they are
17286 computed.
17287 * src/lalr.c (set_state_table): Instead of assigning shifts to
17288 state, just assert that the mapping was properly done.
17289
17290 2001-12-10 Akim Demaille <akim@epita.fr>
17291
17292 * src/LR0.c (insert_start_shift): Rename as...
17293 (insert_start_shifting_state): this.
17294 (insert_eof_shifting_state, insert_accepting_state): New.
17295 (augment_automaton): Adjust.
17296 Better locality of the variables.
17297 When looking if the start_symbol is shifted from the initial
17298 state, using `while (... symbol != start_symbol ...)' sounds
17299 better than `while (... symbol < start_symbol ...)': If fail
17300 to see how the order between symbols could be relevant!
17301
17302 2001-12-10 Akim Demaille <akim@epita.fr>
17303
17304 * src/getargs.h: Don't declare `spec_name_prefix' and
17305 `spec_file_prefix', declared by src/files.h.
17306 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17307 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17308 * src/output.c (prepare): Adjust.
17309 * src/reader.c (symbols_output): Likewise.
17310 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17311
17312 2001-12-10 Akim Demaille <akim@epita.fr>
17313
17314 * src/muscle_tab.c (muscle_init): NULL is a better default than
17315 `"0"'.
17316
17317 2001-12-10 Akim Demaille <akim@epita.fr>
17318
17319 * src/reader.c (reader): Calling symbols_output once is enough.
17320
17321 2001-12-10 Akim Demaille <akim@epita.fr>
17322
17323 Now that states have a complete set of members, the linked list of
17324 reductions is useless: just fill directly the state's reductions
17325 member.
17326
17327 * src/state.h (struct reductions): Remove member `number' and
17328 `next'.
17329 * src/LR0.c (first_reduction, last_reduction): Remove.
17330 (save_reductions): Don't link the new reductions, store them in
17331 this_state.
17332 * src/lalr.c (set_state_table): No need to attach reductions to
17333 states, it's already done.
17334 * src/output.c (output_actions): No longer free the shifts, then
17335 the reductions, then the states: free all the states and their
17336 members.
17337
17338 2001-12-10 Akim Demaille <akim@epita.fr>
17339
17340 * src/options.c (OPTN, DRTV, BOTH): New.
17341 (option_table): Use them.
17342
17343 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17344 the job of system.h.
17345 * src/options.c: Don't include stdio.h and xalloc.h for the same
17346 reasons.
17347
17348 2001-12-10 Akim Demaille <akim@epita.fr>
17349
17350 * src/output.c (output, prepare): Make sure the values of the
17351 muscles `action' and `prologue' are 0-terminated.
17352
17353 2001-12-10 Akim Demaille <akim@epita.fr>
17354
17355 Clean up GCC warnings.
17356
17357 * src/reader.c (copy_action): `buf' is not used.
17358 (parse_skel_decl): Be static.
17359 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17360 * src/options.h (create_long_option_table): Have a real prototype.
17361 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17362 (hash_delete_at): Return const void *.
17363 Adjust casts to preserve the const.
17364
17365 2001-12-10 Akim Demaille <akim@epita.fr>
17366
17367 * configure.in: Require 2.52g.
17368 M4 is not needed, but AUTOM4TE is.
17369 * m4/m4.m4: Remove.
17370 * tests/Makefile.am: Adjust.
17371
17372 2001-12-10 Akim Demaille <akim@epita.fr>
17373
17374 One structure for states is enough, even though theoretically
17375 there are LR(0) states and LALR(1) states.
17376
17377 * src/lalr.h (state_t): Remove.
17378 (state_table): Be state_t **, not state_t *.
17379 * src/state.h (core, CORE_ALLOC): Rename as...
17380 (state_t, STATE_ALLOC): this.
17381 Add the LALR(1) members: shifts, reductions, errs.
17382 * src/LR0.c (state_table): Rename as...
17383 (state_hash): this, to avoid name clashes with the global
17384 `state_table'.
17385 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17386 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17387
17388 2001-12-10 Akim Demaille <akim@epita.fr>
17389
17390 Bison dumps core on bash.y.
17391 Reported by Pascal Bart.
17392
17393 * src/warshall.c (bitmatrix_print): New.
17394 (TC): Use it.
17395 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17396 j must be the outer loop.
17397 * tests/regression.at (Broken Closure): New.
17398
17399 2001-12-05 Akim Demaille <akim@epita.fr>
17400
17401 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17402 its argument.
17403 Reported by Peter Hamorsky.
17404
17405 2001-12-05 Akim Demaille <akim@epita.fr>
17406
17407 * src/conflicts.c (err_table): Remove.
17408 (resolve_sr_conflict): Adjust.
17409 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17410 Rename as...
17411 (state_t.reductions, state_t.shifts): this.
17412
17413 2001-12-05 Akim Demaille <akim@epita.fr>
17414
17415 * src/reduce.c (reduce_grammar_tables): No longer disable the
17416 removal of useless rules via CPP but via `if (0)', so that the
17417 compiler still check the code is valid.
17418 For instance, it should have noticed `rline' no longer exists: use
17419 the `line' member of rule_t.
17420 * src/gram.c (dummy, rline): Remove, unused.
17421
17422 2001-12-05 Akim Demaille <akim@epita.fr>
17423
17424 * src/output.c (pack_vector): Use assert, not berror.
17425 * src/main.c (berror): Remove, unused.
17426
17427 2001-12-05 Akim Demaille <akim@epita.fr>
17428
17429 New experimental feature: if --verbose --trace output all the
17430 items of a state, not only its kernel.
17431
17432 * src/print.c (print_core): If `trace_flag', then invoke closure
17433 before outputting the items of the state (print_core is no longer
17434 a correct name them).
17435 (print_results): Invoke new_closure/free_closure if needed.
17436
17437 2001-12-05 Akim Demaille <akim@epita.fr>
17438
17439 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17440 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17441 (nitemset): for consistency with the rest of the project.
17442
17443 2001-12-05 Akim Demaille <akim@epita.fr>
17444
17445 * src/closure.c (print_closure): Improve.
17446 (closure): Use it for printing input and output.
17447
17448 2001-12-05 Akim Demaille <akim@epita.fr>
17449
17450 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17451 indexed by nonterminals.
17452
17453 2001-12-05 Akim Demaille <akim@epita.fr>
17454
17455 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17456 what it was!).
17457 * src/warshall.h: Remove accidental duplication of the content.
17458
17459 2001-12-05 Akim Demaille <akim@epita.fr>
17460
17461 * src/closure.c (set_fderives): De-obfuscate.
17462
17463 2001-12-05 Akim Demaille <akim@epita.fr>
17464
17465 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
17466
17467 2001-12-05 Akim Demaille <akim@epita.fr>
17468
17469 * src/closure.c (set_firsts): De-obfuscate.
17470
17471 2001-12-05 Akim Demaille <akim@epita.fr>
17472
17473 * src/output.c (action_row): De-obfuscate
17474 using the good o' techniques: arrays not pointers, variable
17475 locality, BITISSET, RESETBIT etc.
17476
17477 2001-12-05 Akim Demaille <akim@epita.fr>
17478
17479 Pessimize the code to simplify it: from now on, all the states
17480 have a valid SHIFTS, which NSHIFTS is possibly 0.
17481
17482 * src/LR0.c (shifts_new): Be global and move to..
17483 * src/state.c, src/state.h: here.
17484 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17485 * src/print_graph: Adjust.
17486
17487 2001-12-05 Akim Demaille <akim@epita.fr>
17488
17489 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17490 * src/conflicts.c: Use it.
17491 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17492 incorrectly ``simplified''.
17493
17494 2001-12-05 Akim Demaille <akim@epita.fr>
17495
17496 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17497 using the good o' techniques: arrays not pointers, variable
17498 locality, BITISSET, RESETBIT etc.
17499
17500 2001-12-05 Akim Demaille <akim@epita.fr>
17501
17502 * src/state.h (SHIFT_SYMBOL): New.
17503 * src/conflicts.c: Use it to deobfuscate.
17504
17505 2001-12-05 Akim Demaille <akim@epita.fr>
17506
17507 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17508 (print_reductions): De-obfuscate using the good o' techniques:
17509 arrays not pointers, variable locality, BITISSET.
17510
17511 2001-12-05 Akim Demaille <akim@epita.fr>
17512
17513 * src/conflicts.c (print_reductions): Arrays, not pointers.
17514 Use BITISSET.
17515
17516 2001-12-05 Akim Demaille <akim@epita.fr>
17517
17518 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17519
17520 2001-12-05 Akim Demaille <akim@epita.fr>
17521
17522 * src/conflicts.c (print_reductions): Improve variable locality.
17523
17524 2001-12-05 Akim Demaille <akim@epita.fr>
17525
17526 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17527
17528 2001-12-05 Akim Demaille <akim@epita.fr>
17529
17530 * src/conflicts.c (print_reductions): Improve variable locality.
17531
17532 2001-12-05 Akim Demaille <akim@epita.fr>
17533
17534 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17535 * src/lalr.c: Use them.
17536
17537 2001-12-05 Akim Demaille <akim@epita.fr>
17538
17539 * src/LR0.c (augment_automaton): Formatting changes.
17540 Better variable locality.
17541
17542 2001-12-05 Akim Demaille <akim@epita.fr>
17543
17544 * src/lalr.c (matrix_print): New.
17545 (transpose): Use it.
17546 Use arrays instead of pointers.
17547
17548 2001-12-05 Akim Demaille <akim@epita.fr>
17549
17550 * src/lalr.c (maxrhs): Move to...
17551 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17552 * src/lalr.c (build_relations): Adjust.
17553
17554 2001-12-05 Akim Demaille <akim@epita.fr>
17555
17556 * src/lalr.c (transpose): Free the memory allocated to the
17557 argument, as it is replaced by the results by the unique caller.
17558 (build_relations): Merely invoke transpose: it handles the memory
17559 deallocation.
17560 Improve variable locality.
17561 Avoid variables used as mere abbreviations.
17562 (compute_lookaheads): Use arrays instead of pointers.
17563
17564 2001-12-05 Akim Demaille <akim@epita.fr>
17565
17566 * src/lalr.c (initialize_F): Improve variable locality.
17567 Avoid variables used as mere abbreviations.
17568
17569 2001-12-05 Akim Demaille <akim@epita.fr>
17570
17571 * src/derives.c (print_derives): Display the ruleno.
17572 * src/lalr.c (initialize_F, transpose): Better variable locality
17573 to improve readability.
17574 Avoid variables used as mere abbreviations.
17575
17576 2001-12-05 Akim Demaille <akim@epita.fr>
17577
17578 * src/lalr.c (traverse): Use arrays instead of pointers.
17579
17580 2001-12-05 Akim Demaille <akim@epita.fr>
17581
17582 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17583 the handling of squeue.
17584 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17585
17586 2001-12-05 Akim Demaille <akim@epita.fr>
17587
17588 Because useless nonterminals are now kept alive (instead of being
17589 `destroyed'), we now sometimes examine them, and store information
17590 related to them. Hence we need to know their number, and adjust
17591 memory allocations.
17592
17593 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17594 static.
17595 * src/LR0.c (allocate_itemsets): The memory allocated to
17596 `symbol_count' was used for two different purpose: once to count
17597 the number of occurrences of each symbol, and later reassigned to
17598 `shift_symbol', containing the symbol that can be shifted from a
17599 given state.
17600 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17601 only, and...
17602 (new_itemsets): Allocate `shift_symbol' here.
17603 (allocate_itemsets): symbol_count includes useless nonterminals.
17604 Make room for them.
17605 (free_storage): Use `free', not `XFREE', for pointers that cannot
17606 be null.
17607
17608 2001-12-05 Akim Demaille <akim@epita.fr>
17609
17610 * src/nullable.c (set_nullable): Deobfuscate the handling of
17611 ritem.
17612 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17613
17614 2001-12-05 Akim Demaille <akim@epita.fr>
17615
17616 * src/gram.c, src/gram.h (ritem_print): New.
17617 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17618 (This useless function was defined only to work around VMS linkers
17619 that can't handle compilation units with variables only).
17620 * src/reduce.c (dump_grammar): Use it to trace the construction of
17621 ritem.
17622
17623 2001-12-04 Paul Eggert <eggert@twinsun.com>
17624
17625 * src/bison.simple (union yyalloc): Change member names
17626 to be the same as the stack names.
17627 (yyparse): yyptr is now union yyalloc *, not char *.
17628 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17629 and may generate better code on some machines.
17630 (yystpcpy): Use prototype if __STDC__ is defined, not just
17631 if __cplusplus is defined.
17632
17633 2001-11-30 Akim Demaille <akim@epita.fr>
17634
17635 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17636 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17637 Gettext doesn't compile cleanly, and dies with -Werror.
17638 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17639 Include WARNING_CFLAGS here.
17640 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17641 before being defined.
17642
17643 2001-11-27 Paul Eggert <eggert@twinsun.com>
17644
17645 * lib/quotearg.h (quotearg_n, quotearg_n_style):
17646 First arg is int, not unsigned.
17647 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
17648 (SIZE_MAX, UINT_MAX): New macros.
17649 (quotearg_n_options): Abort if N is negative.
17650 Avoid overflow check on hosts where size_t is 64 bits and int
17651 is 32 bits, as overflow is impossible there.
17652 Fix off-by-one typo that caused unnecessary reallocation.
17653
17654 2001-11-29 Paul Eggert <eggert@twinsun.com>
17655
17656 Name space cleanup in generated parser.
17657
17658 * doc/bison.texinfo (Bison Parser): Discuss system headers
17659 and their effect on the user name space.
17660
17661 * src/bison.simple:
17662 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
17663 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
17664 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
17665
17666 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
17667 on user names when possible.
17668
17669 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
17670 Simplify test for whather <alloca.h> exists.
17671
17672 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
17673
17674 (<stdio.h>): Include if YYDEBUG.
17675
17676 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
17677 ! defined (yyoverflow) && ! defined (yymemcpy).
17678
17679 (yymemcpy, yyparse): Rename local variables as needed so that
17680 they all begin with 'yy'.
17681

17705
17706 2001-11-30 Akim Demaille <akim@epita.fr>
17707
17708 Instead of mapping the LHS of unused rules to -1, keep the LHS
17709 valid, but flag the rules as invalid.

17712 * src/print.c (print_grammar): Adjust.
17713 * src/derives.c (set_derives): Likewise.

17747 an arbitrary restriction on hosts where size_t is wider than int.
17748
17749 (yyparse): Don't dump core if alloca or malloc fails; instead, report
17750 a parser stack overflow. Allocate just one block of memory for all
17751 three stacks, instead of allocating three blocks; this typically is
17752 faster and reduces fragmentation.
17753
17754 Do not limit the number of items in the stack to a value that fits
17755 in 'int', as this is an arbitrary limit on hosts with 64-bit
17756 size_t and 32-bit int.

18184 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

19560
19561 * src/conflicts.c (conflict_report): Be sure not to append to res

19568 New, from fileutils 4.0.37.
19569 * configure.in: Require Autoconf 2.49c. I took some time before
19570 making this decision. This is the only way out for portability
19571 issues in Bison, it would mean way too much duplicate effort to
19572 import in Bison features implemented in 2.49c since 2.13.
19573 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
19574

19586 (init_lex): Initialize it. No longer call...
19587 (grow_token_buffer): this. Remove it.

19589
19590 2001-01-19 Akim Demaille <akim@epita.fr>
19591
19592 * src/lex.h: Rename all the tokens:
19593 s/\bENDFILE\b/tok_eof/g;
19594 s/\bIDENTIFIER\b/tok_identifier/g;
19595 etc.
19596 Let them be enums, not #define, to ease debugging.
19597 Adjust all the code.
19598
19599 2001-01-18 Akim Demaille <akim@epita.fr>
19600
19601 * src/lex.h (MAXTOKEN, maxtoken, grow_token_buffer): Remove, private.

19603
19604 2001-01-18 Akim Demaille <akim@epita.fr>
19605
19606 Since we now use obstacks, more % directives can be enabled.
19607
19608 * src/lex.c (percent_table): Also accept `%yacc',
19609 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and
19610 `%debug'.
19611 Handle the actions for `%semantic_parser' and `%pure_parser' here,
19612 instead of returning a token.
19613 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
19614 * src/reader.c (read_declarations): Adjust.
19615 * src/files.c (open_files): Don't call `compute_base_names', don't
19616 compute `attrsfile' since they depend upon data which might be
19617 *in* the input file now.
19618 (output_files): Do it here.
19619 * src/output.c (output_headers): Document the fact that this patch
19620 introduces a guaranteed SEGV for semantic parsers.
19621 * doc/bison.texinfo: Document them.
19622 * tests/suite.at: Exercise these %options.
19623

19637

19642
19643 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)
19644 (copy_dollar): Now that everything uses obstacks, get rid of the
19645 FILE * parameters.
19646
19647 2000-12-20 Akim Demaille <akim@epita.fr>
19648
19649 * src/files.c (open_files): Actually the `.output' file is based
19650 on the short_base_name, not base_name.
19651 * tests/suite.at (Checking output file names): Adjust.
19652
19653 2000-12-20 Akim Demaille <akim@epita.fr>

19672 (output_files): Adjust.
19673 (base_name, short_base_name): Be global.
19674 Adjust dependencies.
19675
19676 2000-12-19 Akim Demaille <akim@epita.fr>
19677
19678 * src/files.c (strsuffix): New.
19679 (stringappend): Be just like strcat but allocate.
19680 (base_names): Eve out from open_files.
19681 Try to simplify the rather hairy computation of base_name and
19682 short_base_name.
19683 (open_files): Use it.
19684 * tests/suite.at (Checking output file names): New test.
19685
19686 2000-12-19 Akim Demaille <akim@epita.fr>
19687
19688 * src/system.h (obstack_grow_literal_string): Rename as...
19689 (obstack_grow_string): this.
19690 * src/output.c (output_parser): Recognize `%% actions' instead of

19694
19695 2000-12-19 Akim Demaille <akim@epita.fr>
19696

19701
19702 2000-12-19 Akim Demaille <akim@epita.fr>
19703
19704 Let the handling of the skeleton files be local to the procedures
19705 that use it.

19721
19722 2000-12-19 Akim Demaille <akim@epita.fr>
19723
19724 * src/files.c (open_files): Yipee! We no longer need all the code
19725 looking for `/tmp' since we have no tmp file.
19726
19727 2000-12-19 Akim Demaille <akim@epita.fr>
19728
19729 * src/system.h (EXT_TAB, EXT_OUTPUT, EXT_STYPE_H, EXT_GUARD_C):

19740

19755
19756 * lib/obstack.h: Formatting changes.
19757 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
19758 prevents type checking.
19759 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
19760 cast the value to (void *): assigning a `foo *' to a `void *'
19761 variable is valid.
19762 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
19763 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

19779
19780 * src/bison.s1 (_YY_DECL_VARIABLES, YY_DECL_VARIABLES): New
19781 macros.

19794

19796 defining.
19797 * src/bison.s1: s/#ifdef YYLSP_NEEDED/#if YYLSP_NEEDED/.
19798
19799 2000-11-07 Akim Demaille <akim@epita.fr>
19800
19801 * src/bison.s1 (YYLEX): Use #if instead of #ifdef.
19802 Merge in a single CPP if/else.
19803
19804 2000-11-07 Akim Demaille <akim@epita.fr>
19805
19806 * src/output.c (output): Remove useless variables.
19807 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
19808 argument `data' for consistency with the prototypes.
19809 Qualify it `const'.
19810 (obstack_copy, obstack_copy0): Rename the second argument as
19811 `address' for consistency. Qualify it `const'.
19812 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
19813 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
19814 `const' their input argument (`data' or `address').

19818
19819 * src/Makefile.am (INCLUDES): s/PFILE/BISON_SIMPLE/.

19823 2000-11-03 Akim Demaille <akim@epita.fr>
19824
19825 For some reason, this was not applied.
19826
19827 * src/files.c [VMS]: No longer include `ssdef.h', no longer define

19829
19830 2000-11-03 Akim Demaille <akim@epita.fr>
19831
19832 * src/files.c (skeleton_find): New function, eved out of...

19841 (output_files): this.
19842 Use `obstack_save'.

19844 it no longer has to remove tmp files, just call `output_files'

19921 (copy_guard): Adjust.
19922

19965
19966 2000-10-02 Paul Eggert <eggert@twinsun.com>
19967
19968 * bison.s1 (yyparse): Assign the default value
19969 unconditionally, to avoid a GCC warning and make the parser a
19970 tad smaller.

19973
19974 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
19975 options.
19976
19977 2000-10-02 Akim Demaille <akim@epita.fr>
19978
19979 * src/derives.c, src/print.c, src/reduce.c: To ease the
19980 translation, move some `\n' out of the translated strings.
19981
19982 2000-10-02 Akim Demaille <akim@epita.fr>
19983
19984 The location tracking mechanism is precious for parse error
19985 messages. Nevertheless, it is enabled only when `@n' is used in
19986 the grammar, which is a different issue (you can use it in error
19987 message, but not in the grammar per se). Therefore, there should
19988 be another means to enable it.
19989
19990 * src/getargs.c (getargs): Support `--locations'.
19991 (usage): Report it.
19992 * src/getargs.h (locationsflag): Export it.
19993 * src/lex.c (percent_table): Support `%locations'.
19994 * src/reader.c (yylsp_needed): Remove this variable, now replaced
19995 with `locationsflag'.
19996 * doc/bison.texinfo: Document `--locations' and `%locations'.
19997 Sort the options.
19998 * tests/calc.m4: Test it.
19999
20000 For regularity of the names, replace each
20001 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20002 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20003 In addition replace each `flag' with `_flag'.
20004
20005 2000-10-02 Akim Demaille <akim@epita.fr>
20006
20007 Also test parse error messages, including with YYERROR_VERBOSE.
20008
20009 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20010 associative).
20011 Use it to check the computations.
20012 Use it to check `nonassoc' is honored.
20013 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20014 `--yyerror-verbose'.
20015 (_AT_CHECK_CALC): Adjust to this option.
20016 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
20017
20018 2000-10-02 Akim Demaille <akim@epita.fr>
20019
20020 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20021 the latter demonstrates a flaw in the handling of non debugging
20022 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20023 was used in order to simplify:
20024
20025 #if YYDEBUG
20026 if (yydebug)
20027 {
20028 ...
20029 }
20030 #endif
20031
20032 into
20033
20034 if (yydebug)
20035 {
20036 ...
20037 }
20038
20039 unfortunately this leads to a CPP conflict when
20040 `--name-prefix=foo' is used since it produces `#define yydebug
20041 foodebug'.
20042
20043 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20044 (YYDPRINTF): New macro.
20045 Spread its use.
20046 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20047 the bison options.
20048 Also test `--verbose', `--defines' and `--name-prefix'.
20049
20050 2000-10-02 Akim Demaille <akim@epita.fr>
20051
20052 Improve the readability of the produced parsers.
20053
20054 * src/bison.s1: Formatting changes.
20055 Improve the comment related to the `$' mark.
20056 (yydefault): Don't fall through to `yyresume': `goto' there.
20057 * src/output.c (output_parser): When the `$' is met, skip the end
20058 of its line.
20059 New variable, `number_of_dollar_signs', to check there's exactly
20060 one `$' in the parser skeleton.
20061
20062 2000-10-02 Akim Demaille <akim@epita.fr>
20063
20064 * lib/xstrdup.c: New file, from the fileutils.
20065 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20066 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20067 instead of strlen + xmalloc + strcpy.
20068 * src/symtab.c (copys): Remove, use xstrdup instead.
20069
20070 2000-10-02 Akim Demaille <akim@epita.fr>
20071
20072 * src/gram.h (associativity): New enum type which replaces the
20073 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
20074 `right_assoc', `left_assoc' and `non_assoc'.
20075 Adjust all dependencies.
20076 * src/reader.c: Formatting changes.
20077 (LTYPESTR): Don't define it, use it as a literal in
20078 `reader_output_yylsp'.
20079 * src/symtab.h (symbol_class): New enum type which replaces the
20080 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
20081 `sunknown', `stoken and `snterm'.
20082
20083 2000-10-02 Akim Demaille <akim@epita.fr>
20084
20085 * src/getargs.c (fixed_outfiles): Rename as...
20086 (yaccflag): for consistency and accuracy.
20087 Adjust dependencies.
20088
20089 2000-10-02 Akim Demaille <akim@epita.fr>
20090
20091 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20092 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20093 difficult and introduced a lot of core dump. It turns out that
20094 Bison used an implementation of `xmalloc' based on `calloc', and
20095 at various places it does depend upon the initialization to 0. I
20096 have not tried to isolate the pertinent places, and all the former
20097 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20098 someone should address this issue.
20099
20100 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20101 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

20145 * src/conflicts.h: New file.
20146 Propagate its inclusion.
20147
20148 2000-10-02 Akim Demaille <akim@epita.fr>

20175 prototypes.
20176 * src/reader.c: Formatting changes, topological sort,
20177 s/register//.
20178
20179 2000-10-02 Akim Demaille <akim@epita.fr>
20180

20194
20195 * src/output.c (token_actions): Introduce a temporary array,
20196 YYDEFACT, that makes it possible for this function to use
20197 output_short_table.
20198
20199 2000-10-02 Akim Demaille <akim@epita.fr>
20200
20201 `user_toknums' is output as a `short[]' in `output.c', while it is
20202 defined as a `int[]' in `reader.c'. For consistency with the
20203 other output tables, `user_toknums' is now defined as a table of
20204 shorts.
20205
20206 * src/reader.c (user_toknums): Be a short table instead of an int
20207 table.
20208 Adjust dependencies.

20245 inclusion.
20246 Don't define PARAMS.
20247 * src/system.h: Define PARAMS.
20248 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the

20250 definitions in config.h.
20251
20252 2000-09-20 Akim Demaille <akim@epita.fr>

20279 * tests/calc.m4 (yyin): Be initialized in main, not on the global
20280 scope.
20281 (yyerror): Returns void, not int.
20282 * doc/bison.texinfo: Formatting changes.
20283
20284 2000-09-19 Akim Demaille <akim@epita.fr>

20468 Change the handling of @s so that they behave exactly like $s.
20469 There is now a pseudo variable @$ (readble and writable), location
20470 of the lhs of the rule (by default ranging from the location of
20471 the first symbol of the rhs, to the location of the last symbol,

20507 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

21235 way to specify the flags -n, -l, and -r. Also added hooks for
21236 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
21237 major changes to files.c.
21238 (lex) Retain in the incoming stream a character following
21239 an incorrect '/'.
