69 portability: fix several issues with M4 subprocess.
70
71 M4's output pipe was not being drained upon fatal errors during
72 scan_skel. As a result, broken-pipe messages from M4 were seen
73 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
74 failure in the test suite. The problem was that, on platforms
75 where the default disposition for SIGPIPE is ignore instead of
76 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
77 then reported it. However, there's some sort of race condition,
78 because the new test group occasionally succeeded.
79 Reported by Albert Chin at
80 <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
81
82 There were also problems with the test suite livelocking on
83 Tru64 5.1b. Reported by Didier Godefroy at
84 <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
85 Switching to create_pipe_bidi suggested by Akim Demaille.
86
87 To attempt to solve both of these problems, switch to gnulib's
88 create_pipe_bidi and register M4 process as a slave. Along the
89 way, clean up file name conflict handling, which was affected by
90 the broken-pipe problem before the switch.
91 * NEWS (2.4.2): Document.

100 of output_file_name_check.
101 (output_file_name_check): In the case that the grammar file
102 would be overwritten, use complain instead of fatal, but replace
103 the output file name with /dev/null. Use the /dev/null solution
104 for the case of two conflicting output files as well because it
105 seems safer in case Bison one day tries to open both files at
106 the same time.
107 * src/files.h (output_file_name_check): Update prototype.

228 portability: `<' and `>' are not always defined on addresses.

253 Fix handling of yychar manipulation in user semantic actions.
254 The problem was that yacc.c didn't always update the yychar
255 translation afterwards. However, other skeletons appear to be
256 fine. glr.c appears to already translate yychar before every
257 use. lalr1.cc does not define yychar and does not document its
258 replacement, yyla, for users. It does provide yyclearin, but
259 that does not manipulate yyla and thus requires no translation
260 update. In lalr1.java, yychar is out of scope during semantic
261 actions.
262 * NEWS (2.5): Document.
263 * data/yacc.c (YYBACKUP): Don't bother translating yychar into
264 yytoken here.
265 (yyparse, yypush_parse): Instead, translate before every use of
266 yytoken, and add comments explaining this approach.
267 * tests/actions.at (Destroying lookahead assigned by semantic
268 action): New test group checking that translation happens before
269 lookahead destructor calls at parser return. Previously,
270 incorrect destructors were called.
271 * tests/conflicts.at (parse.error=verbose and consistent
272 errors): New test group checking that translation happens at
273 syntax error detection before the associated verbose error
274 message and the associated lookahead destructor calls. While
275 the destructor call is fixed by this patch, the verbose error
276 message is currently incorrect due to another bug (see
277 comments in test group), so this is an expected failure for now.

470 yysyntax_error: avoid duplicate lookahead collection.
471 Except when memory reallocation is required, this change
472 eliminates the need to invoke yysyntax_error twice and thus to
473 repeat the collection of lookaheads. It also prepares for
474 future extensions that will make those repetitions more
475 expensive and that will require additional memory management in
476 yysyntax_error. Finally, it fixes an obscure bug already
477 exercised in the test suite.
478 * data/yacc.c (yysyntax_error): Add arguments for message
479 buffer variables stored in the parser. Instead of size, return
480 status similar to yyparse status but indicating success of
481 message creation. Other than the actual reallocation of the

483 from...

862 is invoked, and so adding the check here is probably redundant.
863 However, the code may evolve after this subtlety is forgotten.
864 Also, update for rename to yytable_value_is_error. Because that

945 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
946 For a \0 and similar escape sequences meaning the null
947 character, report an invalid escape sequence instead of an
948 invalid null character because the latter does not actually
949 appear in the user's input.
950 In all escape sequence complaints, don't escape the initial
951 backslash, and don't quote when the sequence appears at the end
952 of the complaint line unless there's whitespace that quotearg
953 won't escape.
954 Consistently say "invalid" not "unrecognized".
955 Consistently prefer "empty character literal" over "extra
956 characters in character literal" warning for invalid escape
957 sequences; that is, consistently discard those sequences.

1096 build: fix the generation of the documentation.
1097 Some of our targets use "bison --help", but they can't depend on
1098 "bison" itself (to avoid additional requirements on the user), so
1099 they used to call "make src/bison" in the commands. Then
1100 concurrent builds may fail: one make might be aiming one of its
1101 jobs at compiling src/bison, and another job at generating the man
1102 page. If the latter is faster than the former, then we have two
1103 makes that concurrently try to compile src/bison.

2148 lalr1.cc: avoid GCC 4.3 warnings.
2149 GCC 4.3 now warns about "a || b && c" and asks for explicit
2150 parentheses.
2151 Reported by Alexandre Duret-Lutz.
2152 * data/location.cc: Update copyright years.
2153 (Position::operator==): Use parens to make precedence explicit.
2154 Compare lines and columns first, as they are more likely to be
2155 different, and they are faster to compare.

2179 Yes, this obfuscates the point of this example, variants only.

2692 They were used to get the symbol types, given a rule number, when
2693 displaying the top of the stack before a reduction. But the
2694 symbol type is available from the state stack. This has two be

3213 Finer input type for yytranslate.
3214 This patch is debatable: the tradition expects yylex to return an int
3215 which happens to correspond to token_number (which is an enum). This
3216 allows for instance to return characters (such as '*' etc.). But this
3217 goes against the stronger typing I am trying to have with the new
3218 lex interface which return a symbol_type. So in this case, feed
3219 yytranslate_ with a token_type.

3396 Introduce make_symbol.
b06df3c2
AD
3397 make_symbol provides a means to construct a full symbol (kind,
3398 value, location) in a single shot. It is meant to be a Symbol
3399 constructor, parameterized by the symbol kind so that overloading
3400 would prevent incorrect kind/value pairs. Unfortunately
3401 parameterized constructors do not work well in C++ (unless the
3402 parameter also appears as an argument, which is not acceptable),
3403 hence the use of a function instead of a constructor.

3431 which obviously meant to catch spaces and tabs, but contained only

3618 Change the handling of the symbols in the skeletons.
3619 Before we were using tables which lines were the symbols and which
3620 columns were things like number, tag, type-name etc. It is was
3621 difficult to extend: each time a column was added, all the numbers had
3622 to be updated (you asked for colon $2, not for "tag"). Also, it was
3623 hard to filter these tables when only a subset of the symbols (say the
3624 tokens, or the nterms, or the tokens that have and external number
3625 *and* a type-name) was of interest.
de62edee 3626
d69c9694

3627 Now instead of monolithic tables, we define one macro per cell. For
3628 instance "b4_symbol(0, tag)" is a macro name which contents is
3629 self-decriptive. The macro "b4_symbol" provides easier access to
3630 these cells.

3816 Rely on the state stack to display reduction traces.
b06df3c2

3817 To display rhs symbols before a reduction, we used information
3818 about the rule reduced, which required the tables yyrhs and
3819 yyprhs. Now use rely only on the state stack to get the same
3820 information.

3948 Add "%define assert" to variants.
3949 This is used to help the user catch cases where some value gets
3950 ovewritten by a new one. This should not happen, as this will
3951 probably leak.
de62edee 3952
2d32fc9f
AD
3953 Unfortunately this uncovered a bug in the C++ parser itself: the
3954 lookahead value was not destroyed between two calls to yylex. For
3955 instance if the previous lookahead was a std::string, and then an int,
3956 then the value of the std::string was correctly taken (i.e., the
3957 lookahead was now an empty string), but std::string structure itself
3958 was not reclaimed.
de62edee 3959
2d32fc9f
AD
3960 This is now done in variant::build(other&) (which is used to take the
3961 value of the lookahead): other is not only stolen from its value, it
3962 is also destroyed. This incurs a new performance penalty of a few
3963 percent, and union becomes faster again.

4244 Fuse the three stacks into a single one.

4246 In order to make it easy to perform benchmarks to ensure that
4247 there are no performance loss, lalr1.cc is forked into
4248 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
4249 lalr1.cc.
4250
4251 Meanwhile, to make sure that lalr1-fusion.cc is correctly
4252 exercized by the test suite, the user must install a symbolic link
4253 from lalr1.cc to it.

4255 Instead of having three stacks (state, value, location), use a
4256 stack of triples. This considerably simplifies the code (and it
4257 will be easier not to require locations as currently does the C++
4258 parser), and also gives a 10% speedup according to
4259 etc/bench (probably mainly since memory allocation is done once
4260 instead of three times).

4262 Another motivation is to make it easier to destruct properly
4263 semantic values: now that they are bound to their state (hence
4264 symbol type) it will be easier to call the appropriate destructor.

0e0ed236 4266 These changes should probably benefit the C parser too.

4288 have been pushed before. yystate still must be the new state.
4289 This allows to use yypush_ everywhere instead of individual
4290 handling of the stacks.

4311 Use variants to support objects as semantic values.
b06df3c2
AD
4312 This patch was inspired by work by Michiel De Wilde. But he used
4313 Boost variants which (i) requires Boost on the user side, (ii) is
4314 slow, and (iii) has useless overhead (the parser knows the type of
4315 the semantic value there is no reason to duplicate this
4316 information as Boost.Variants do).
4317
4318 This implementation reserves a buffer large enough to store the
4319 largest objects. yy::variant implements this buffer. It was
4320 implemented with Quentin Hocquet.

6017 * src/lalr.c (state_lookahead_tokens_count): For code readability,
6018 move the check for disabled transitions to an aver since conflict
6019 resolution hasn't happened yet.
6020
6021 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
6022 labels a state as inconsistent just because it has error transitions.
6023 The original form of this check appeared in revision 1.1 of lalr.c,
6024 which was committed on 1991-12-21. Now (at least), changing the
6025 consistency label on such a state appears to have no useful effect in
6026 any of the places it is examined, which I enumerate below. The key
6027 point to understanding each item in this enumeration is that a state
6028 with an error transition is labelled consistent in the first place only
6029 if it has no rules, so the check cannot matter for states that have
6030 rules. (1) Labelling a state as inconsistent will cause set_conflicts
6031 to try to identify its conflicts, and a state must have *rules* to have
6032 conflicts. (2) Labelling a state as inconsistent will affect how
6033 action_row sets the default *rule* for the state. (3) Labelling a
6034 state as inconsistent will cause build_relations to add lookback edges
6035 to *rules* in that state.
6036 * src/state.h (struct state): Word the comment for member consistent
6037 more carefully.

6546 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use

6610 params with digraphs.
6611 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default

6675 Instead of having skeletons declare all valid %define variables and
6676 %code qualifiers, provide macros that retrieve the associated values
6677 and build these lists automatically. Thus Bison will now warn when a
6678 variable or qualifier is not used by the skeleton in the current
6679 invocation regardless of whether it might sometimes be used by that
6680 skeleton in other invocations. Also, move all %define value macros to
6681 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
6682 form, which is replaced by %code.
6683 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
6684 (b4_check_user_names): ... this, and change the series of valid name
6685 arguments to a single list argument for names used in the skeleton
6686 similar to the existing list argument for names used in the grammar.
6687 Warn instead of complaining.
6688 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
6689 values and %code code, to format %code code properly, and to build
6690 lists of all %define variables and %code qualifiers used in the
6691 skeleton: b4_skeleton_percent_define_variables and
6692 b4_skeleton_percent_code_qualifiers.
6693 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
6694 Remove, and...

6696 the skeleton names lists can finish building first. In place of
6697 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
6698 expect the lists b4_user_percent_define_variables and
6699 b4_user_percent_code_qualifiers.

6701 b4_location_type, b4_filename_type, b4_namespace, and
6702 b4_define_location_comparison, update their names to the
6703 b4_percent_define_ namespace.
6704 * data/glr.c: Don't use b4_check_percent_define_variables and
6705 b4_check_percent_code_qualifiers. Use b4_get_percent_code.

6714 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
6715 Rename to...
6716 (muscle_grow_user_name_list): ... this for consistency with the
6717 terminology used in bison.m4.
6718 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
6719 %define variable names, and rename muscle used_percent_define_variables
6720 to user_percent_define_variables.
6721 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
6722 user_percent_code_qualifiers.
6723 (content): Remove.

6748 name list muscles that b4_check_for_unrecognized_names requires.

6821 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
6822 the previous removal of uses of m4_divert, which caused trouble.
6823 (b4_check_percent_code_qualifiers): Use b4_complain instead of

6975 Encapsulate code properties and related functionality for the various
6976 destructors, printers, and actions into a code_props structure and
6977 interface. This patch merely implements code_props in scan-code.h and
6978 scan-code.l. Future patches will rewrite other modules to use it.
6979 Discussed starting at
6980 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
6981 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
6982 consistently initialize const structs that have an empty location
6983 field.
6984 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
6985 to ensure consistency.
6986 * src/scan-code.h (code_props): New structure.
6987 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
6988 function, macro, and const global variable for initializing a
6989 code_props with no code.
6990 (code_props_plain_init, code_props_symbol_action_init,
6991 code_props_rule_action_init, code_props_translate_code): The rest of
6992 the new code_props functional interface. Among other things, the init
6993 functions set the code_props kind field so that
6994 code_props_translate_code will know whether to behave like
6995 translate_symbol_action, translate_rule_action, or translate_code.
6996 These old translate functions must remain until all other modules are
6997 updated to use the new code_props interface.
6998 (code_scanner_last_string_free): New function similar to
6999 gram_scanner_last_string_free.
7000 (code_scanner_free): Add documentation.
7001 * src/scan-code.l: Implement the new interface.
7002 (code_lex): Make it static, add a code_props* argument, and remove the
7003 rule argument.
7004 (last_string): New static global similar to the one in scan-gram.l.
7005 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
7006 instead of rule.
7007 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
7008 code_props since Bison may one day use this information for destructors
7009 and printers.
7010 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
7011 (handle_action_dollar): Use symbol_list_n_get and set used flag
7012 directly since symbol_list_n_used_set is removed.
7013 (translate_action): Add a code_props* argument and remove the rule,
7014 action, and location arguments. Pass the code_props* on to code_lex.
7015 (translate_rule_action, translate_symbol_action, translate_code):
7016 Rewrite as wrappers around the new code_props interface.
7017 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
7018 it would eventually need to break the encapsulation of code_props.

7144 Enable push parsers to operate in impure mode. Thus, %push-parser no
7145 longer implies %pure-parser. The point of this change is to move
7146 towards being able to test the push parser code by running the entire
7147 test suite as if %push-parser had been declared.
7148 * data/push.c (yypush_parse): For impure mode, remove the
7149 yypushed_char, yypushed_val, and yypushed_loc arguments.
7150 Instead, declare these as local variables initialized to the global
7151 yychar, yylval, and yylloc.

7156 %push-parser.
7157 * tests/calc.at (Simple LALR(1) Calculator): Always declare

7202 initialized (with b4_location_initial_line and
7203 b4_location_initial_column) upon calling yypush_parse. However, that
7204 initialization now overwrites the first token's location;
7205 %initial-action assigning @$ already did the same thing, and both bugs

7410 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
7411 `bison ', use m4_index instead of m4_substr since chopping up a string
7412 containing M4-special characters causes problems here.
7413
7414 Fix a couple of bugs related to special characters in user-specified
7415 file names, and make it easier for skeletons to compute output file
7416 names with the same file name prefix as Bison-computed output file
7417 names.
7418 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
7419 b4_parser_file_name and b4_spec_defines_file instead of
7420 @output_parser_name@ and @output_header_name@, which are now redundant.
7421 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
7422 b4_parser_file_name, b4_spec_defines_file, and the new
7423 @basename(FILENAME@) instead of @output_parser_name@ and
7424 @output_header_name@, which inappropriately escaped the file names as

7433 characters are escaped properly.
7434 * src/output.c (prepare): Define muscle file_name_all_but_ext as
7435 all_but_ext.
7436 For pkgdatadir muscle, maintain previous functionality by using
7437 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
7438 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
7439 digraphs would never be expanded. Hopefully no one has M4-special
7440 characters in his Bison installation path.
7441 * src/scan-skel.l: Don't parse @output_header_name@ and
7442 @output_parser_name@ anymore since they're now redundant.
7443 In @output, use decode_at_digraphs.

8310 Whether the default %destructor/%printer applies to a particular symbol
8311 isn't a question of whether the user *declares* that symbol (in %token,
8312 for example). It's a question of whether the user by any means
8313 *defines* the symbol at all (by simply using a char token, for
8314 example). $end is defined by Bison whereas any other token with token
8315 number 0 is defined by the user. The error token is always defined by
8316 Bison regardless of whether the user declares it with %token, but we
8317 may one day let the user define error as a nonterminal instead.

8486 Enable declaration of default %printer/%destructor. Make the parser
8487 use these for all user-declared grammar symbols for which the user does
8488 not declare a specific %printer/%destructor. Thus, the parser uses it
8489 for token 0 if the user declares it but not if Bison generates it as
8490 $end. Discussed starting at
8491 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
8492 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
8493 and
8494 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
8495 * NEWS (2.3+): Mention.
8496 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
8497 declare a %destructor for a mid-rule's semantic value. It's just
8498 impossible to declare one specific to it.
8499 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
8500 code. Describe default %destructor form.
8501 * src/parse-gram.y (grammar_declaration): Parse default
8502 %printer/%destructor declarations.
8503 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
8504 and symbol_destructor_location_get rather than accessing the destructor
8505 and destructor_location members of struct symbol.
8506 (symbol_printers_output): Likewise but for %printer's.
8507 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
8508 again.
8509 * src/symtab.c (default_destructor, default_destructor_location,
8510 default_printer, default_printer_location): New static global
8511 variables to record the default %destructor and %printer.
8512 (symbol_destructor_get, symbol_destructor_location_get,
8513 symbol_printer_get, symbol_printer_location_get): New functions to
8514 compute the appropriate %destructor and %printer for a symbol.
8515 (default_destructor_set, default_printer_set): New functions to set the
8516 default %destructor and %printer.
8517 * src/symtab.h: Prototype all those new functions.
8518 * tests/actions.at (Default %printer and %destructor): New test to
8519 check that the right %printer and %destructor are called, that they're
8520 not called for $end, and that $$ and @$ work correctly.
8521 (Default %printer and %destructor for user-declared end token): New
8522 test to check that the default %printer and %destructor are called for
8523 a user-declared end token.
8524 * tests/input.at (Default %printer and %destructor redeclared, Unused
8525 values with default %destructor): New tests to check related grammar
8526 warnings and errors.

8530 Clean up handling of %destructor for the end token (token 0).
8531 Discussed starting at
8532 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>

8534 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
8535
8536 Make the skeletons consistent in how they pop the end token and invoke
8537 its %destructor.
8538 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
8539 state, which has token number 0, since this would invoke the
8540 %destructor for the end token.
8541 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
8542 until after shifting the end token, or else it won't be popped.
8543 * data/yacc.c (yyparse): Likewise.
8544
8545 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
8546 it's the end token. Upon termination, destroy an unshifted lookahead
8547 even when it's the end token.
8548 * data/lalr1.cc (yy::parser::parse): Likewise.
8549 * data/yacc.c (yyparse): Likewise.
8550
8551 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
8552 value warnings for the end token when the user gives the end token a
8553 %destructor.
8554
8555 * tests/actions.at (Printers and Destructors): Test all the above.

8563 overwritten by autopoint.
8564 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
8565 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
8566 rejects them.
8567 Don't use autoreconf; instead, invoke autopoint etc. by hand,
8568 so that we can remove the intl files at a better time.
8569 (intl_files_to_remove): Remove aclocal.m4, since it gets
8570 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
8571 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,

8573 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
8574 Remove datarootdir hack; no longer needed.
8575 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
8576 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
8577 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
8578 strdup.h.
8579 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.

8634 YYSTYPE if your grammar contains at least one <type> tag.

8706 this was never guaranteed, and now that we're using gnulib stdint,

8718 no longer copies it.

8720 since stdint needs the former and wcwidth (which is now required
8721 by mbswidth) needs the latter.
8722 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to

8745 since we now use the stdint module.
8746 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
8747 HAVE_UINTPTR_T, since we now use the stdint module.

8839 * src/scan-code.l (handle_action_dollar): Now that this is invoked
8840 after parsing the entire grammar file, the symbol list here in the case
8841 of a midrule is actually the midrule's empty RHS, so reference its

9378 Also, the embedded comments in this test case claim it checks the case

9380 corresponding LHS was already resolved, so yyresolveLocations didn't
9381 actually have reason to modify it. Fix this by forcing
9382 nondeterministic operation at the beginning of the parse.

10855 Use unlocked I/O for a minor performance improvement on hosts like
10856 GNU/Linux and Solaris that support unlocked I/O. The basic idea

11306 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
11307 that the byte '\0xff' is not printable in the C locale; it is,
11308 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

11438 removed once the bison-runtime domain has been translated by each
11439 team.

11525 Some English-language cleanups for %destructor.

11535 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
11536 (yyparse): Rename yyoverflowlab to yyexhaustedlab.

11538 Rename yyoverflowab to yyexhaustedlab.
11539 When memory exhaustion occurs during syntax-error reporting,
11540 report it separately rather than in a single diagnostic; this
11541 eases translation.

11549 Add i18n support to the GLR skeleton. Partially fix the C++
11550 skeleton; a C++ expert needs to finish this. Remove debugging
11551 msgids; there's little point to having them translated, since they
11552 can be understood only by someone who can read the
11553 (English-language) source code.
11554
11555 Generate runtime-po/bison-runtime.pot automatically, so that we
11556 don't have to worry about garbage getting in that file. We'll
11557 make sure after the next official release that old msgids don't
11558 get lost. See

11564 Fix typos in explanations of the runtime file.
11565 * bootstrap: Change gettext keyword from YYI18N to YY_.
11566 Use standard Makefile.in.in in runtime-po, since we'll arrange
11567 for backward-compatible bison-runtime.po files in a different way.
11568 * data/glr.c (YY_): New macro, from yacc.c.
11569 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
11570 Translate messages intended for users.
11571 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
11572 the wording in the other skeletons. We don't know that the memory
11573 is virtual.
11574 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
11575 Use same method that yacc.c uses.
11576 Don't translate debugging messages.
11577 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
11578 it doesn't work (yet), and requires C++ expertise to fix.

11580 Move defn to a more logical place, to be consistent with other
11581 skeletons.
11582 Don't translate debugging messages.
11583 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
11584 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
11585 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.

11599 All uses removed.
11600 (yyStackOverflow): Just longjmp, but with value 2 so that caller
11601 can handle the problem.
11602 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
11603 (yyparse): New local variable yyresult to record the result.

11605 struct.
11606 (yyDone): Remove label.
11607 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
11608 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
11609 if YYABORT is used).
11610 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
11611 yyparse status; put status > 1 into diagnostic.

11936 conftest*, for benefit of CVS commands run at the same time as
11937 "configure". Add build-aux, since "bootstrap" now creates it and
11938 its subfiles.
11939 * Makefile.cfg (move_if_change): Remove.
11940 * Makefile.maint: Remove the update stuff; we now use "bootstrap".

11960 fopen-safer.c, stdio-safer.h, unistd-safer.h.
11961 * lib/subpipe.c: Include "unistd-safer.h".
11962 (create_subpipe): Make sure all the newly-created
11963 file descriptors are > 2, so that diagnostics don't
11964 get sent down them (which might cause Bison to hang, in theory).

12382 Remove uses of 'short int' and 'unsigned short int'. This raises
12383 some arbitrary limits. It uses more memory but nowadays that's
12384 not much of an issue.

12386 This change does not affect the generated parsers; that's a different
12387 task, as some users will want to conserve memory there.

12790 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
12791 whether the reducion was empty or not. This leaves room to
12792 improve the use of YYLLOC_DEFAULT in such a case.
12793 lalr1.cc is still experimental, so changing this is acceptable.
12794 And finally, there are probably not many users who changed the
12795 handling of locations in GLR, so changing is admissible too.

12943 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
12944 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
12945 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
12946 the extra Bison directives instead of the whole series.
12947 Change the grammar so that there are recoverable errors, and
12948 unrecoverable errors. Now we can have the parser give up before
12949 consuming the whole input. As a result we now can observe that
12950 the lookahead is freed when needed.
12951 Change the parser source to parse argv[1] instead of a hard coded
12952 string.
12953 Simplify yylex, and give a value and location to EOF.
12954 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
12955 passed directives already coded in the file.
12956 Add some tests to check the location of "error".
12957 For some tests, the C++ parser is correct, and not yacc.c.
12958 For other tests, they provide different, but unsatisfying, values,
12959 so keep the C++ value so that at least one parser is "correct"
12960 according to the test suite.

13140 Spent a few hours checking out which prerequisite versions the
13141 current sources actually require. I went all the way back to
13142 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
13143 a seemingly endless set of combinations of versions more recent
13144 than that. The bottom line is that the current sources require
13145 fairly recent versions of the build tools, and it'll be some work
13146 to change this.

13381 case, as stos_ is now used by destructors due to the 2004-02-09
13382 change.

13408 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
13409 so that this include file can stand alone.
13410 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
13411 does this now. Include subpipe.h first after config.h, to
13412 test whether it can stand alone.
13413
13414 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
13415 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
13416 unused declaration.
13417
13418 * tests/synclines.at (%union synch line): Put a dummy member in
13419 the union, because empty unions aren't allowed in C. Caught

13662 When reducing initial empty rules, Bison parser read an initial
13663 location that is not defined. This results in garbage, and that
13664 affects Bison's own parser. Therefore we need (i) to extend Bison

13714 yyerrlab), when hitting EOF, pop the whole stack here instead of
13715 merely falling thru the default error handling mechanism.
13716 (yyerrorlab): New label, with the old contents of YYERROR,
13717 plus the following change: pop the stack of rhs corresponding
13718 to the production that invoked YYERROR. That is how Yacc
13719 behaves (required by POSIX).

26ec81e0

13961 The problem was that GLR parsers did not conform to the C standard,
13962 because actions like { $1 = $2 + $3; } expanded to expressions
13963 that invoked YYFILL in separate subexpressions, and YYFILL assigned
13964 to a local variable. The C standard says that expressions
13965 like (var = f ()) + (var = f ()) have undefined behavior.
13966 Another problem was that GCC sometimes issues warnings that
13967 yyfill and its parameters are unused.
13968
13969 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
13970 as possibly unused.
13971 (yyfill): New function.
13972 (YYFILL): Use it.
13973 (yyuserAction): Change type of yynormal to bool, so that it matches
13974 the new yyfill signature. Mark it as possibly unused.
13975
13976
13977 Follow up on a bug I reported in February, where a Bison-generated
13978 parser can loop. Provide a test case and a fix for yacc.c. I
13979 don't have a fix for lalr1.cc or for glr.c, unfortunately.
13980 The original bug report is in:

13982
13983 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
13984 macro's size was becoming unwieldy.
13985 (yyerrlab): Do not discard an empty lookahead symbol, as this
13986 might destroy garbage.
13987 (yyerrorlab): New label, with the old contents of YYERROR,
13988 plus the following change: pop the stack of rhs corresponding
13989 to the production that invoked YYERROR. That is how Yacc
13990 behaves, and POSIX requires this behavior.
13991 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
13992 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
13993 Define 'alarm' to do nothing if unistd.h is not available.
13994 Add a new rule "exp: '-' error;" to test the above change to
13995 data/yacc.c. Use 'alarm' to abort any test taking longer than
13996 10 seconds, as it's probably looping.
13997 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
13998 Also, the new yacc.c generates two fewer diagnostics for an
13999 existing test.

14627 we don't need to worry about yyerrlab1 being reported as an

14649 popped). This means that the initial elements will not be freed
14650 explicitly, as is the case in yacc.c; it is not a problem, as
14651 these elements have fake values.

14784 Fix a bug where error locations were not being recorded correctly.
14785 This problem was originally reported by Paul Hilfinger in
161a71f3 14786 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.

14788 * data/yacc.c (yyparse): New local var yylerrsp, to record the
14789 top of the location stack's error locations.
14790 (yyerrlab): Set it. When discarding a token, push its location
14791 onto yylerrsp so that we don't lose track of the error's end.
14792 (yyerrlab1): Now is only the target of YYERROR, so that we can
14793 properly record the location of the action that failed. For GCC
14794 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
14795 GCC warning about yyerrlab1 being unused if YYERROR is unused.
14796 (yyerrlab2): New label, which yyerrlab now falls through to.
14797 Compute the error's location by applying YYLLOC_DEFAULT to
14798 the locations of all the symbols that went into the error.
14799 * doc/bison.texinfo (Location Default Action): Mention that
14800 YYLLOC_DEFAULT is also invoked for syntax errors.
14801 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
14802 Error locations include the locations of all the tokens that were
14803 discarded, not just the last token.

14860 If the user does not define YYSTYPE as a macro, Bison now declares it
14861 using typedef instead of defining it as a macro. POSIX requires this.
14862 For consistency, YYLTYPE is also declared instead of defined.
14863
14864 %union directives can now have a tag before the `{', e.g., the
14865 directive `%union foo {...}' now generates the C code
14866 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
14867 The default union tag is `YYSTYPE', for compatibility with Solaris 9
14868 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
14869 instead of `yyltype'.
14870
14871 `yystype' and `yyltype' are now obsolescent macros instead of being
14872 typedefs or tags; they are no longer documented and will be
14873 withdrawn in a future release.
14874

14879 (YYLTYPE): Renamed from yyltype.
14880 (yyltype, yystype): New (and obsolescent) macros,
14881 for backward compatibility.
14882 * data/yacc.c: Likewise.
14883
14884 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
14885 does not specify a union tag. This is for compatibility with
14886 Solaris 9 yacc.
14887
14888 * src/parse-gram.y (add_param): 2nd arg is now char * not char

14893 trailing " {...}". Now of type <chars>.
14894 (grammar_declaration): Adjust to bundled tokens.

14905 has (or usually has) an immediately-following braced code.

14907 to return when scanning braced code.

14985 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
14986 Similarly for DERIVES.

15308 instead of returning ID immediately, since we need to search for
15309 a subsequent colon.
15310 (<INITIAL>"'", "\""): Save token_start.

15899 strings now.

15904 (prepare_symbols): Quote tokens for M4.
15905 (prepare): Don't insert output_infix, output_prefix,
15906 output_parser_name, output_header_name; this is now down by scan-skel.
15907 Insert skeleton as a C string.
15908

15911 * src/reader.c (prologue_augment, epilogue_set): Likewise.
15912
15913 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
15914 escapes other than \\ and \'; this simplifies the code.

15916 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
15917 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
15918 Use new escapes @{ and @} for [ and ].
15919

15921 them with auto vars.
15922 Switch to new escape scheme, where @ is the escape character uniformly.
15923 Abort if a stray escape character is found. Avoid unbounded input
15924 buffer when parsing non-escaped text.
15925

15939 counted in the token inserted at end of file. Now takes
15940 location_t *, not location_t, so that the location can be
15941 adjusted. All uses changed.

15961
15962 Remove nounput option. At an unexpected end of file, we now unput

16297 Be consistent about 'bool'; the old code used an enum in one
16298 module and an int in another, and this violates the C standard.

16655 Let nondeterministic skeletons be usable with deterministic
16656 tables.
16657
16658 With the patch, GAWK compiled by GCC without -O2 passes its test
16659 suite using a GLR parser driven by LALR tables. It fails with -O2
16660 because `struct stat' gives two different answers on my machine:
16661 88 (definition of an auto var) and later 96 (memset on this var).
16662 Hence the stack is badly corrumpted. The headers inclusion is to
16663 blame: if I move the awk.h inclusion before GLR's system header
16664 inclusion, the two struct stat have the same size.

16982 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
16983 to BITSET_WINDEX_MAX.

16985 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
16986 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

17138 functions are not portable. Do not assume size_t is the
17139 same width as int.
17140 (yypstates): Do not assume that ptrdiff_t is the same width
17141 as int, and similarly for yyposn and YYINDEX.
17142

17183 PROTOTYPES to check for prototypes, and "defined __STDC__" to
17184 check for void *.
17185
17186 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
17187 size_t; the old version tried to do this but casted improperly.
17188 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
17189 (bitset_test): Now returns int, not unsigned long.

17192 (_): New macro.

17194 name locals "index", as it generates unnecessary warnings on some

17221 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
17222 manual recommends.
17223 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

17226 (strerror): Use same pattern as ../lib/error.c.

17233 to void, to avoid a GCC warning when --disable-nls is in effect.
17234
17235 * src/scan-gram.l: Use strings rather than escapes when possible,
17236 to minimize the number of warnings from xgettext.
17237 (handle_action_dollar, handle_action_at): Don't use isdigit,
17238 as it mishandles negative chars and it may not work as expected
17239 outside the C locale.
17240
17241 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
17242 this is a GCC extension and is not portable to other compilers.
17243
17244 * src/system.h (alloca): Use same pattern as ../lib/error.c.
17245 Do not include <ctype.h>; no longer needed.
17246 Do not include <malloc.h>; no longer needed (and generates
17247 warnings on OpenBSD 3.0).
17248
17249 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
17250 it's not portable.
17251
17252 * tests/regression.at: Do not use 'cc -c input.c -o input';
17253 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
17254
17255 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
17256 exit status as failure, not just exit status 1. Sun C exits
17257 with status 2 sometimes.
17258

20083 Equip the skeleton chain with location tracking, runtime trace,

20085
20086 * src/parse-skel.y: Request a pure parser, locations, and prefix
20087 renaming.
20088 (%union): Having several members with the same type does not help
20089 type mismatches, simplify.

20109 problems: because Flex includes the headers *before* us,
20110 _GNU_SOURCE is not defined by config.h, and therefore strndup was
20111 not visible.

20129 Don't use %option yylineno: it seems that then Flex imagines
20130 REJECT has been used, and therefore it won't reallocate its
20131 buffers (which makes no other sense to me than a bug). It results
20132 in warnings for `unused: yy_flex_realloc'.

20881 The computation of nullable is broken: it doesn't handle empty
20882 RHS's properly.

20884 * tests/torture.at (GNU AWK Grammar): New.
20885 * tests/sets.at (Nullable): New.

20887 `ritems', loop over the rules, and then over their rhs's.

20889 Work around Autotest bugs.
20890
20891 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
20892 frame, because Autotest understand lines starting with a `+' as
20893 traces from the shell. Then, they are not processed properly.
20894 Admittedly an Autotest bug, but we don't have time to wait for
20895 Autotest to catch up.

20912 * src/print_graph.c (print_core): Complete the set of items via
20913 closure. The next-to-final and final states are still unsatisfying,
20914 but that's to be addressed elsewhere.
20915 No longer output the rule numbers, but do output the state number.
20916 A single loop for the shifts + gotos is enough, but picked a
20917 distinct color for each.

21325 Because useless nonterminals are now kept alive (instead of being
21326 `destroyed'), we now sometimes examine them, and store information
21327 related to them. Hence we need to know their number, and adjust

21333 `symbol_count' was used for two different purpose: once to count
21334 the number of occurrences of each symbol, and later reassigned to
21335 `shift_symbol', containing the symbol that can be shifted from a
21336 given state.
21337 Deobfuscate, i.e., allocate, use and free `symbol_count' here
21338 only, and...
21339 (new_itemsets): Allocate `shift_symbol' here.
21340 (allocate_itemsets): symbol_count includes useless nonterminals.

21343 be null.

23721 The location tracking mechanism is precious for parse error
23722 messages. Nevertheless, it is enabled only when `@n' is used in
23723 the grammar, which is a different issue (you can use it in error

23757 Test also `--verbose', `--defines' and `--name-prefix'. Testing
23758 the latter demonstrates a flaw in the handling of non debugging
23759 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
23760 was used in order to simplify:
23761
23762 #if YYDEBUG
23763 if (yydebug)
23764 {

23771 if (yydebug)
23772 {
23773 ...
23774 }
23775

23828 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
23829 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
23830 difficult and introduced a lot of core dump. It turns out that
23831 Bison used an implementation of `xmalloc' based on `calloc', and
23832 at various places it does depend upon the initialization to 0. I
23833 have not tried to isolate the pertinent places, and all the former
23834 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

24954 (printable_version, int_to_string, warn, warni, warns, warnss)
24955 (warnsss): New error reporting functions. Avoid abort for error.
24956
24957 * src/lex.h:
24958 Added THONG and NOOP for alias processing.
24959 Added SETOPT for the new code that allows setting options with %flags.
24960
24961 * src/lex.c:
24962 Include getopt.h. Add some extern decls.

24972 way to specify the flags -n, -l, and -r. Also added hooks for
24973 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
24974 major changes to files.c.
24975 (lex) Retain in the incoming stream a character following
24976 an incorrect '/'.
24977 (skip_white_space, lex): Revised most error messages
