3 Fix portability issue in the test suite.
4 * tests/local.at (AT_MATCHES_CHECK): New.
5 Based on Perl instead of Sed. Sed has too many portability
6 pitfalls, not ever Sed is GNU Sed.
7 * tests/actions.at (Fix user actions without a trailing semicolon):
8 Use it.

43 if it seems necessary.
44 * src/scan-code.l (flex rules section): Flag cpp directive from
45 any `#' to the first unescaped end-of-line. Semicolon is not
46 needed after `;', `{', '}', or cpp directives and is needed after
47 any other token (whitespaces and comments have no effect).

30c10faf
AD
116 Instead of defining complex list of tuples to define various
117 properties of the symbols, we now prefer to define symbols as
118 "structs" in m4: using the symbol key (its number), and the
119 property name, b4_symbol gives it value. Use this to handle
120 destructors and printers.

145 Convert lib/Makefile.am into lib/local.mk.
146 The real problem is rather gnulib.mk, which itself is extracted
147 from a Makefile.am that gnulib expects to the "recursive". The
148 tool prefix-gnulib-mk converts such a gnulib.mk to be
149 non-recursive. Also, some AC_SUBST variables need to be adjusted.
150
151 * etc/prefix-gnulib-mk: New.
152 * bootstrap (slurp): Use it to convert further gnulib.mk.
153 No longer try to avoid re-creation of lib/gnulib.mk as the changes
154 are deeper.
155 * lib/Makefile.am: Rename as...
156 * lib/local.mk: this.
157 Adjust to be prefixed.

286 They were used to get the symbol types, given a rule number, when
287 displaying the top of the stack before a reduction. But the
288 symbol type is available from the state stack. This has two be
289 benefits: two tables less in the parser (making it smaller), and a
290 more consistent use of the three stacks which will help to fuse
291 them.

488 There are two issues to handle: first scanning nested angle
489 bracket pairs to support types such as std::pair< std::string,

492 Another issue is to address idiosyncracies of C++: do not glue two
493 closing angle brackets together (otherwise it's operator>>), and
494 avoid sticking blindly a TYPE to the opening <, as it can result
495 in '<:' which is a digraph for '['.

807 Finer input type for yytranslate.
808 This patch is debatable: the tradition expects yylex to return an int
809 which happens to correspond to token_number (which is an enum). This
810 allows for instance to return characters (such as '*' etc.). But this
811 goes against the stronger typing I am trying to have with the new

b06df3c2
AD
991 make_symbol provides a means to construct a full symbol (kind,
992 value, location) in a single shot. It is meant to be a Symbol
993 constructor, parameterized by the symbol kind so that overloading
994 would prevent incorrect kind/value pairs. Unfortunately
995 parameterized constructors do not work well in C++ (unless the
996 parameter also appears as an argument, which is not acceptable),
997 hence the use of a function instead of a constructor.

1212 Change the handling of the symbols in the skeletons.
1213 Before we were using tables which lines were the symbols and which
1214 columns were things like number, tag, type-name etc. It is was
1215 difficult to extend: each time a column was added, all the numbers had
1216 to be updated (you asked for colon $2, not for "tag"). Also, it was
1217 hard to filter these tables when only a subset of the symbols (say the
1218 tokens, or the nterms, or the tokens that have and external number
1219 *and* a type-name) was of interest.
de62edee 1220

1221 Now instead of monolithic tables, we define one macro per cell. For
1222 instance "b4_symbol(0, tag)" is a macro name which contents is
1223 self-decriptive. The macro "b4_symbol" provides easier access to
1224 these cells.

1542 Add "%define assert" to variants.
1543 This is used to help the user catch cases where some value gets
1544 ovewritten by a new one. This should not happen, as this will
1545 probably leak.
de62edee 1546
2d32fc9f
AD
1547 Unfortunately this uncovered a bug in the C++ parser itself: the
1548 lookahead value was not destroyed between two calls to yylex. For
1549 instance if the previous lookahead was a std::string, and then an int,
1550 then the value of the std::string was correctly taken (i.e., the
1551 lookahead was now an empty string), but std::string structure itself
1552 was not reclaimed.
de62edee 1553
2d32fc9f
AD
1554 This is now done in variant::build(other&) (which is used to take the
1555 value of the lookahead): other is not only stolen from its value, it
1556 is also destroyed. This incurs a new performance penalty of a few
1557 percent, and union becomes faster again.

1838 Fuse the three stacks into a single one.

b06df3c2
AD
1840 In order to make it easy to perform benchmarks to ensure that
1841 there are no performance loss, lalr1.cc is forked into
1842 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
1843 lalr1.cc.
1844
1845 Meanwhile, to make sure that lalr1-fusion.cc is correctly
1846 exercized by the test suite, the user must install a symbolic link
1847 from lalr1.cc to it.

1849 Instead of having three stacks (state, value, location), use a
1850 stack of triples. This considerably simplifies the code (and it
1851 will be easier not to require locations as currently does the C++
1852 parser), and also gives a 10% speedup according to
1853 etc/bench (probably mainly since memory allocation is done once
1854 instead of three times).

1856 Another motivation is to make it easier to destruct properly
1857 semantic values: now that they are bound to their state (hence
1858 symbol type) it will be easier to call the appropriate destructor.

1905 Use variants to support objects as semantic values.
b06df3c2
AD
1906 This patch was inspired by work by Michiel De Wilde. But he used
1907 Boost variants which (i) requires Boost on the user side, (ii) is
1908 slow, and (iii) has useless overhead (the parser knows the type of
1909 the semantic value there is no reason to duplicate this
1910 information as Boost.Variants do).
1911
1912 This implementation reserves a buffer large enough to store the
1913 largest objects. yy::variant implements this buffer. It was
1914 implemented with Quentin Hocquet.

3612 move the check for disabled transitions to an aver since conflict
3613 resolution hasn't happened yet.
3614
3615 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3616 labels a state as inconsistent just because it has error transitions.
3617 The original form of this check appeared in revision 1.1 of lalr.c,
3618 which was committed on 1991-12-21. Now (at least), changing the
3619 consistency label on such a state appears to have no useful effect in
3620 any of the places it is examined, which I enumerate below. The key
3621 point to understanding each item in this enumeration is that a state
3622 with an error transition is labelled consistent in the first place only
3623 if it has no rules, so the check cannot matter for states that have
3624 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3625 to try to identify its conflicts, and a state must have *rules* to have
3626 conflicts. (2) Labelling a state as inconsistent will affect how
3627 action_row sets the default *rule* for the state. (3) Labelling a
3628 state as inconsistent will cause build_relations to add lookback edges
3629 to *rules* in that state.

4130 Clean up %define and %code implementation in M4 some. Most
4131 importantly, rename all related macros to be in the b4_percent_define
4132 and b4_percent_code namespaces. Also, complete support for `.' in
4133 %define variable names and %code qualifiers.
4134 * data/bison.m4 (b4_check_user_names): Check for special
4135 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4136 m4_foreach loops.
4137 (b4_get_percent_define, b4_get_percent_code): Rename to...
4138 (b4_percent_define_get, b4_percent_code_get): ... these.
4139 Extend documentation with examples.
4140 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4141 b4_percent_define_skeleton_variables and
4142 b4_percent_code_skeleton_qualifiers.
4143 Expect any value for the %define variable `foo' to be stored in the
4144 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4145 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4146 expect any unqualified %code blocks to be stored in a macro named
4147 `b4_percent_code_unqualified'.
4148 Use m4_indir so that %define variable names and %code qualifiers can
4149 contain `.', which is allowed by the grammar parser.
4150 (b4_percent_define_default): New macro to set a default value for a
4151 %define variable.
4152 (m4_wrap): Update wrapped code, and fix some underquoting.
4153 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4154 Expect grammar uses of %define variables and %code qualifiers to be
4155 defined in b4_percent_define_user_variables and
4156 b4_percent_code_user_qualifiers.
4157 * data/c++.m4: Use b4_percent_define_default rather than
4158 m4_define_default. Fix some underquoting. Skeleton usage of %define
4159 variable define_location_comparison now implies skeleton usage of

4269 Instead of having skeletons declare all valid %define variables and

4271 and build these lists automatically. Thus Bison will now warn when a
4272 variable or qualifier is not used by the skeleton in the current
4273 invocation regardless of whether it might sometimes be used by that
4274 skeleton in other invocations. Also, move all %define value macros to
4275 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
4276 form, which is replaced by %code.
4277 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

4281 Warn instead of complaining.
4282 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

4569 Encapsulate code properties and related functionality for the various
4570 destructors, printers, and actions into a code_props structure and
4571 interface. This patch merely implements code_props in scan-code.h and
4572 scan-code.l. Future patches will rewrite other modules to use it.
4573 Discussed starting at
4574 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
4575 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
4576 consistently initialize const structs that have an empty location
4577 field.
4578 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
4579 to ensure consistency.

4581 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
4582 function, macro, and const global variable for initializing a
4583 code_props with no code.
4584 (code_props_plain_init, code_props_symbol_action_init,
4585 code_props_rule_action_init, code_props_translate_code): The rest of
4586 the new code_props functional interface. Among other things, the init
4587 functions set the code_props kind field so that
4588 code_props_translate_code will know whether to behave like
4589 translate_symbol_action, translate_rule_action, or translate_code.
4590 These old translate functions must remain until all other modules are
4591 updated to use the new code_props interface.
4592 (code_scanner_last_string_free): New function similar to

4598 (last_string): New static global similar to the one in scan-gram.l.
4599 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4600 instead of rule.
4601 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4602 code_props since Bison may one day use this information for destructors
4603 and printers.
4604 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4605 (handle_action_dollar): Use symbol_list_n_get and set used flag
4606 directly since symbol_list_n_used_set is removed.
4607 (translate_action): Add a code_props* argument and remove the rule,
4608 action, and location arguments. Pass the code_props* on to code_lex.
4609 (translate_rule_action, translate_symbol_action, translate_code):
4610 Rewrite as wrappers around the new code_props interface.

4843 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4844 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4845 each NAME in this list to yyps->NAME so it can be used in yypush_parse.

4847 parser state variable declarations with
4848 b4_declare_parser_state_variables.
4849 Don't initialize parser state variables when calling yypush_parse since
4850 yypstate_new already does that.

4852 invocation.

5005 `bison ', use m4_index instead of m4_substr since chopping up a string
5006 containing M4-special characters causes problems here.
5007
5008 Fix a couple of bugs related to special characters in user-specified
5009 file names, and make it easier for skeletons to compute output file
5010 names with the same file name prefix as Bison-computed output file
5011 names.
5012 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5013 b4_parser_file_name and b4_spec_defines_file instead of
5014 @output_parser_name@ and @output_header_name@, which are now redundant.
5015 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5016 b4_parser_file_name, b4_spec_defines_file, and the new
5017 @basename(FILENAME@) instead of @output_parser_name@ and
5018 @output_header_name@, which inappropriately escaped the file names as

5027 characters are escaped properly.
5028 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5029 all_but_ext.
5030 For pkgdatadir muscle, maintain previous functionality by using
5031 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5032 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5033 digraphs would never be expanded. Hopefully no one has M4-special
5034 characters in his Bison installation path.
5035 * src/scan-skel.l: Don't parse @output_header_name@ and

5255 * src/scan-code.h (translate_rule_action):
5256 (translate_symbol_action, translate_code, translate_action): Return
5257 `char const *' rather than `char *' since external code should not free
5258 these strings.
5259 * src/scan-code.l: Likewise.
5260 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
5261 which is "{...}" in the parser.

5263 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
5264 Valgrind.

5266 complain.
5267 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
5268 expecting a non-zero exit status sets --leak-check=summary and
5269 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
5270 this case, and we don't want to hear about it.

5901 Whether the default %destructor/%printer applies to a particular symbol
5902 isn't a question of whether the user *declares* that symbol (in %token,
5903 for example). It's a question of whether the user by any means
5904 *defines* the symbol at all (by simply using a char token, for
5905 example). $end is defined by Bison whereas any other token with token
5906 number 0 is defined by the user. The error token is always defined by
5907 Bison regardless of whether the user declares it with %token, but we
5908 may one day let the user define error as a nonterminal instead.

6969 Also, the embedded comments in this test case claim it checks the case

6971 corresponding LHS was already resolved, so yyresolveLocations didn't
6972 actually have reason to modify it. Fix this by forcing
6973 nondeterministic operation at the beginning of the parse.

8446 Use unlocked I/O for a minor performance improvement on hosts like
8447 GNU/Linux and Solaris that support unlocked I/O. The basic idea

8898 that the byte '\0xff' is not printable in the C locale; it is,
8899 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

9066 Fix more problems reported by twlevo@xs4all.nl.
9067 * tests/cxx-type.at: Don't pipe output of ./types through sed to
9068 remove trailing spaces. This loses the exit status of ./types,
9069 and isn't needed since ./types shouldn't be emitting trailing
9070 spaces.
9071 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
9072 as the stack isn't valid in that case.

9103 Destructor cleanups and regularization among the three skeletons.
9104 * NEWS: Document the behavior changes.
9105 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9106 stack before failing, as the cleanup code will do it for us now.
9107 * data/lalr1.cc (yyerrlab): Likewise.
9108 * data/glr.c (yyparse): Pop everything off the stack before
9109 freeing it, so that destructors get called properly.
9110 * data/lalr1.cc (yyreturn): Likewise.
9111 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9112 This is more consistent.
9113 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9114 why destructors might be called. 1.875 -> 2.1.
9115 (Destructor Decl, Decl Summary, Table of Symbols):
9116 Some English-language cleanups for %destructor.
9117 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

9120 because of that same extra output line.

9126 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9127 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9128 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9129 Rename yyoverflowab to yyexhaustedlab.
9130 When memory exhaustion occurs during syntax-error reporting,
9131 report it separately rather than in a single diagnostic; this
9132 eases translation.

9140 Add i18n support to the GLR skeleton. Partially fix the C++
9141 skeleton; a C++ expert needs to finish this. Remove debugging
9142 msgids; there's little point to having them translated, since they
9143 can be understood only by someone who can read the
9144 (English-language) source code.
9145
9146 Generate runtime-po/bison-runtime.pot automatically, so that we
9147 don't have to worry about garbage getting in that file. We'll
9148 make sure after the next official release that old msgids don't
9149 get lost. See
9150 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9151
9152 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9153 Now auto-generated.
9154 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9155 Fix typos in explanations of the runtime file.
9156 * bootstrap: Change gettext keyword from YYI18N to YY_.
9157 Use standard Makefile.in.in in runtime-po, since we'll arrange
9158 for backward-compatible bison-runtime.po files in a different way.
9159 * data/glr.c (YY_): New macro, from yacc.c.
9160 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9161 Translate messages intended for users.
9162 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9163 the wording in the other skeletons. We don't know that the memory
9164 is virtual.
9165 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9166 Use same method that yacc.c uses.
9167 Don't translate debugging messages.
9168 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
9169 it doesn't work (yet), and requires C++ expertise to fix.
9170 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
9171 Move defn to a more logical place, to be consistent with other
9172 skeletons.
9173 Don't translate debugging messages.
9174 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
9175 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
9176 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
9177 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

9190 All uses removed.
9191 (yyStackOverflow): Just longjmp, but with value 2 so that caller
9192 can handle the problem.
9193 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.

9196 struct.
9197 (yyDone): Remove label.
9198 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
9199 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
9200 if YYABORT is used).
9201 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
9202 yyparse status; put status > 1 into diagnostic.

9487 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
9488 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
9489 the user's name space.

9491 (YYMALLOC, YYFREE): Define only if needed.
9492 (malloc, free): Declare, but only if needed, as this infringes on
9493 the user name space.

9525 Various maintainer cleanups.
9526 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9527 conftest*, for benefit of CVS commands run at the same time as
9528 "configure". Add build-aux, since "bootstrap" now creates it and
9529 its subfiles.
9530 * Makefile.cfg (move_if_change): Remove.
9531 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9532 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9551 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9552 * lib/subpipe.c: Include "unistd-safer.h".
9553 (create_subpipe): Make sure all the newly-created
9554 file descriptors are > 2, so that diagnostics don't
9555 get sent down them (which might cause Bison to hang, in theory).
9556 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.

9973 Remove uses of 'short int' and 'unsigned short int'. This raises
9974 some arbitrary limits. It uses more memory but nowadays that's
9975 not much of an issue.

10381 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
10382 whether the reducion was empty or not. This leaves room to
10383 improve the use of YYLLOC_DEFAULT in such a case.
10384 lalr1.cc is still experimental, so changing this is acceptable.
10385 And finally, there are probably not many users who changed the
10386 handling of locations in GLR, so changing is admissible too.

10534 AT_BISON_OPTION_PUSHDEFS to get correct help macros.

10536 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10537 the extra Bison directives instead of the whole series.
10538 Change the grammar so that there are recoverable errors, and
10539 unrecoverable errors. Now we can have the parser give up before
10540 consuming the whole input. As a result we now can observe that
10541 the lookahead is freed when needed.
10542 Change the parser source to parse argv[1] instead of a hard coded
10543 string.
10544 Simplify yylex, and give a value and location to EOF.
10545 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10546 passed directives already coded in the file.
10547 Add some tests to check the location of "error".
10548 For some tests, the C++ parser is correct, and not yacc.c.
10549 For other tests, they provide different, but unsatisfying, values,
10550 so keep the C++ value so that at least one parser is "correct"
10551 according to the test suite.

10731 Spent a few hours checking out which prerequisite versions the
10732 current sources actually require. I went all the way back to
10733 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10734 a seemingly endless set of combinations of versions more recent
10735 than that. The bottom line is that the current sources require
10736 fairly recent versions of the build tools, and it'll be some work
10737 to change this.
10738 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.

11253 When reducing initial empty rules, Bison parser read an initial
11254 location that is not defined. This results in garbage, and that

161a71f3 11551 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
26ec81e0

11552 The problem was that GLR parsers did not conform to the C standard,
11553 because actions like { $1 = $2 + $3; } expanded to expressions
11554 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11555 to a local variable. The C standard says that expressions
11556 like (var = f ()) + (var = f ()) have undefined behavior.
11557 Another problem was that GCC sometimes issues warnings that
11558 yyfill and its parameters are unused.
11559
11560 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11561 as possibly unused.
11562 (yyfill): New function.
11563 (YYFILL): Use it.
11564 (yyuserAction): Change type of yynormal to bool, so that it matches
11565 the new yyfill signature. Mark it as possibly unused.
11566
11567
11568 Follow up on a bug I reported in February, where a Bison-generated
11569 parser can loop. Provide a test case and a fix for yacc.c. I
11570 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11571 The original bug report is in:

11573
11574 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11575 macro's size was becoming unwieldy.
11576 (yyerrlab): Do not discard an empty lookahead symbol, as this
11577 might destroy garbage.
11578 (yyerrorlab): New label, with the old contents of YYERROR,
11579 plus the following change: pop the stack of rhs corresponding
11580 to the production that invoked YYERROR. That is how Yacc
11581 behaves, and POSIX requires this behavior.
11582 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11583 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11584 Define 'alarm' to do nothing if unistd.h is not available.
11585 Add a new rule "exp: '-' error;" to test the above change to
11586 data/yacc.c. Use 'alarm' to abort any test taking longer than
11587 10 seconds, as it's probably looping.
11588 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11589 Also, the new yacc.c generates two fewer diagnostics for an
11590 existing test.

12240 popped). This means that the initial elements will not be freed
12241 explicitly, as is the case in yacc.c; it is not a problem, as
12242 these elements have fake values.

12379 * data/yacc.c (yyparse): New local var yylerrsp, to record the
12380 top of the location stack's error locations.
12381 (yyerrlab): Set it. When discarding a token, push its location
12382 onto yylerrsp so that we don't lose track of the error's end.
12383 (yyerrlab1): Now is only the target of YYERROR, so that we can
12384 properly record the location of the action that failed. For GCC

12451 If the user does not define YYSTYPE as a macro, Bison now declares it
12452 using typedef instead of defining it as a macro. POSIX requires this.
12453 For consistency, YYLTYPE is also declared instead of defined.
12454
12455 %union directives can now have a tag before the `{', e.g., the
12456 directive `%union foo {...}' now generates the C code
12457 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12458 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12459 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12460 instead of `yyltype'.
12461
12462 `yystype' and `yyltype' are now obsolescent macros instead of being
12463 typedefs or tags; they are no longer documented and will be
12464 withdrawn in a future release.
12465

12471 (yyltype, yystype): New (and obsolescent) macros,
12472 for backward compatibility.
12473 * data/yacc.c: Likewise.
12474
12475 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
12476 does not specify a union tag. This is for compatibility with

12496 has (or usually has) an immediately-following braced code.

12498 to return when scanning braced code.

13513 Switch to new escape scheme, where @ is the escape character uniformly.
13514 Abort if a stray escape character is found. Avoid unbounded input
13515 buffer when parsing non-escaped text.
13516

13525 evaluate to 0 if it's impossible for NINF to be in the respective
13526 table.
13527 (yygetLRActions, yyrecoverParseError): Use them.
13528
13529 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
13530 counted in the token inserted at end of file. Now takes
13531 location_t *, not location_t, so that the location can be
13532 adjusted. All uses changed.

13541 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

13550 stack, since the stack was never deeper than 1; instead, use the
13551 new auto var c_context to record the stacked value.
13552
13553 Remove nounput option. At an unexpected end of file, we now unput
13554 the minimal input necessary to end cleanly; this simplifies the

14246 Let nondeterministic skeletons be usable with deterministic
14247 tables.
14248
14249 With the patch, GAWK compiled by GCC without -O2 passes its test
14250 suite using a GLR parser driven by LALR tables. It fails with -O2
14251 because `struct stat' gives two different answers on my machine:
14252 88 (definition of an auto var) and later 96 (memset on this var).
14253 Hence the stack is badly corrumpted. The headers inclusion is to
14254 blame: if I move the awk.h inclusion before GLR's system header
14255 inclusion, the two struct stat have the same size.

14729 functions are not portable. Do not assume size_t is the
14730 same width as int.
14731 (yypstates): Do not assume that ptrdiff_t is the same width
14732 as int, and similarly for yyposn and YYINDEX.
14733

14774 PROTOTYPES to check for prototypes, and "defined __STDC__" to
14775 check for void *.
14776
14777 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
14778 size_t; the old version tried to do this but casted improperly.

14783 (_): New macro.

14812 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
14813 manual recommends.
14814 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
14815
14816 * src/complain.c (strerror_r): Remove decl; not needed.
14817 (strerror): Use same pattern as ../lib/error.c.
14818
14819 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
14820

14822
14823 * src/main.c (main): Cast result of bindtextdomain and textdomain
14824 to void, to avoid a GCC warning when --disable-nls is in effect.
14825
14826 * src/scan-gram.l: Use strings rather than escapes when possible,
14827 to minimize the number of warnings from xgettext.
14828 (handle_action_dollar, handle_action_at): Don't use isdigit,
14829 as it mishandles negative chars and it may not work as expected
14830 outside the C locale.
14831
14832 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14833 this is a GCC extension and is not portable to other compilers.

14836 Do not include <ctype.h>; no longer needed.
14837 Do not include <malloc.h>; no longer needed (and generates
14838 warnings on OpenBSD 3.0).
14839
14840 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14841 it's not portable.
14842
14843 * tests/regression.at: Do not use 'cc -c input.c -o input';
14844 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14845
14846 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14847 exit status as failure, not just exit status 1. Sun C exits
14848 with status 2 sometimes.
14849
14850 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
14851 Use it for the two large tests.

15018 parsers now contain `reduce 0' as default reduction.

17698 Throw away MS-DOS crap: we don't need getpid.

17700 problems: because Flex includes the headers *before* us,
17701 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17702 not visible.

17720 Don't use %option yylineno: it seems that then Flex imagines
17721 REJECT has been used, and therefore it won't reallocate its
17722 buffers (which makes no other sense to me than a bug). It results
17723 in warnings for `unused: yy_flex_realloc'.

18068 Be sure to preserve the value of the eoftoken.
18069 (reader): Make sure eoftoken is defined.

18071 * src/print.c (print_grammar): Don't special case the eof token.
18072 * src/regression.at: Adjust: `$' has value 0, not -1, which was a

18215 `lookaheadsp' member of the following state (since lookaheads of

18916 Because useless nonterminals are now kept alive (instead of being
18917 `destroyed'), we now sometimes examine them, and store information
18918 related to them. Hence we need to know their number, and adjust
18919 memory allocations.

18921 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18922 static.
18923 * src/LR0.c (allocate_itemsets): The memory allocated to
18924 `symbol_count' was used for two different purpose: once to count
18925 the number of occurrences of each symbol, and later reassigned to
18926 `shift_symbol', containing the symbol that can be shifted from a
18927 given state.
18928 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18929 only, and...
18930 (new_itemsets): Allocate `shift_symbol' here.
18931 (allocate_itemsets): symbol_count includes useless nonterminals.
18932 Make room for them.
18933 (free_storage): Use `free', not `XFREE', for pointers that cannot
18934 be null.

19076
19077 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19078 a parser stack overflow. Allocate just one block of memory for all
19079 three stacks, instead of allocating three blocks; this typically is
19080 faster and reduces fragmentation.

19082 Do not limit the number of items in the stack to a value that fits

21312 The location tracking mechanism is precious for parse error
21313 messages. Nevertheless, it is enabled only when `@n' is used in
21314 the grammar, which is a different issue (you can use it in error
21315 message, but not in the grammar per se). Therefore, there should

21348 Test also `--verbose', `--defines' and `--name-prefix'. Testing
21349 the latter demonstrates a flaw in the handling of non debugging
21350 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
21351 was used in order to simplify:
21352
21353 #if YYDEBUG
21354 if (yydebug)
21355 {
21356 ...
21357 }
21358 #endif

21360 into
21361
21362 if (yydebug)
21363 {
21364 ...
21365 }
21366
21367 unfortunately this leads to a CPP conflict when
21368 `--name-prefix=foo' is used since it produces `#define yydebug
21369 foodebug'.

21419 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21420 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21421 difficult and introduced a lot of core dump. It turns out that
21422 Bison used an implementation of `xmalloc' based on `calloc', and
21423 at various places it does depend upon the initialization to 0. I
21424 have not tried to isolate the pertinent places, and all the former
21425 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
21426 someone should address this issue.

22563 way to specify the flags -n, -l, and -r. Also added hooks for
