3 tests: skip tests of file names that platform does not support.
4 Reported by Michael Raskin at
5 <http://lists.gnu.org/archive/html/bug-bison/2009-09/msg00001.html>.
6 * THANKS (Michael Raskin): Add.
7 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Fix. Cygwin used
8 to fail at least for file names containing ":" or "\".

12 yysyntax_error: avoid duplicate lookahead collection.
13 Except when memory reallocation is required, this change
14 eliminates the need to invoke yysyntax_error twice and thus to
15 repeat the collection of lookaheads. It also prepares for
16 future extensions that will make those repetitions more
17 expensive and that will require additional memory management in
18 yysyntax_error. Finally, it fixes an obscure bug already
19 exercised in the test suite.
20 * data/yacc.c (yysyntax_error): Add arguments for message
21 buffer variables stored in the parser. Instead of size, return
22 status similar to yyparse status but indicating success of
23 message creation. Other than the actual reallocation of the
24 message buffer, import and clean up memory management code
25 from...
26 (yyparse, yypush_parse): ... here.
27 * tests/regression.at (%error-verbose overflow): No longer an
28 expected failure.

263 defined.
264 * data/glr.c, data/lalr1.cc, data/lalr1.java, data/yacc.c: Fix
265 yytable comments: zero indicates syntax error not default
266 action.

269 (yyisDefaultedState): Update for rename.
270 (yyis_table_ninf): Rename to...
271 (yytable_value_is_error): ... this, and check for value zero
272 besides just YYTABLE_NINF.
273 (yygetLRActions): Check for default value from yypact. It
274 appears that this check is always performed before this function
275 is invoked, and so adding the check here is probably redundant.
276 However, the code may evolve after this subtlety is forgotten.
277 Also, update for rename to yytable_value_is_error. Because that
278 macro now checks for zero, a different but equivalent branch of
279 the if-then-else here is evaluated.
280 (yyreportSyntaxError): Update for rename to
281 yytable_value_is_error. The zero condition was mishandled
282 before.
283 (yyrecoverSyntaxError): Update for renames. No behavioral
284 changes.
285 * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
286 New function.
287 (yy_table_value_is_error_): New function.
288 (parse): Use new functions where possible. No behavioral
289 changes.
290 (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
291 The zero condition was mishandled before.
292 * data/yacc.c (yyis_pact_ninf): Rename to...
293 (yypact_value_is_default): ... this.
294 (yyis_table_ninf): Rename to...
295 (yytable_value_is_error): ... this, and check for value zero
296 besides just YYTABLE_NINF.
297 (yysyntax_error): Update for rename to yytable_value_is_error.
298 The zero condition was mishandled before.
299 (yyparse): Update for renames. No behavioral changes.
300 * src/tables.h: Improve comments about yypact, yytable, etc.
301 more. Most importantly, say yytable value of zero means syntax
302 error not default action.

358 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
359 For a \0 and similar escape sequences meaning the null
360 character, report an invalid escape sequence instead of an
361 invalid null character because the latter does not actually
362 appear in the user's input.
363 In all escape sequence complaints, don't escape the initial
364 backslash, and don't quote when the sequence appears at the end
365 of the complaint line unless there's whitespace that quotearg
366 won't escape.
367 Consistently say "invalid" not "unrecognized".
368 Consistently prefer "empty character literal" over "extra
369 characters in character literal" warning for invalid escape
370 sequences; that is, consistently discard those sequences.

3207 move the check for disabled transitions to an aver since conflict
3208 resolution hasn't happened yet.
3209
3210 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
3211 labels a state as inconsistent just because it has error transitions.
3212 The original form of this check appeared in revision 1.1 of lalr.c,
3213 which was committed on 1991-12-21. Now (at least), changing the
3214 consistency label on such a state appears to have no useful effect in
3215 any of the places it is examined, which I enumerate below. The key
3216 point to understanding each item in this enumeration is that a state
3217 with an error transition is labelled consistent in the first place only
3218 if it has no rules, so the check cannot matter for states that have
3219 rules. (1) Labelling a state as inconsistent will cause set_conflicts
3220 to try to identify its conflicts, and a state must have *rules* to have
3221 conflicts. (2) Labelling a state as inconsistent will affect how
3222 action_row sets the default *rule* for the state. (3) Labelling a
3223 state as inconsistent will cause build_relations to add lookback edges
3224 to *rules* in that state.

3725 Clean up %define and %code implementation in M4 some. Most
3726 importantly, rename all related macros to be in the b4_percent_define
3727 and b4_percent_code namespaces. Also, complete support for `.' in
3728 %define variable names and %code qualifiers.
3729 * data/bison.m4 (b4_check_user_names): Check for special
3730 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3731 m4_foreach loops.
3732 (b4_get_percent_define, b4_get_percent_code): Rename to...
3733 (b4_percent_define_get, b4_percent_code_get): ... these.
3734 Extend documentation with examples.
3735 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3736 b4_percent_define_skeleton_variables and
3737 b4_percent_code_skeleton_qualifiers.
3738 Expect any value for the %define variable `foo' to be stored in the
3739 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3740 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3741 expect any unqualified %code blocks to be stored in a macro named
3742 `b4_percent_code_unqualified'.
3743 Use m4_indir so that %define variable names and %code qualifiers can
3744 contain `.', which is allowed by the grammar parser.
3745 (b4_percent_define_default): New macro to set a default value for a
3746 %define variable.
3747 (m4_wrap): Update wrapped code, and fix some underquoting.
3748 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3749 Expect grammar uses of %define variables and %code qualifiers to be
3750 defined in b4_percent_define_user_variables and
3751 b4_percent_code_user_qualifiers.
3752 * data/c++.m4: Use b4_percent_define_default rather than
3753 m4_define_default. Fix some underquoting. Skeleton usage of %define
3754 variable define_location_comparison now implies skeleton usage of
3755 %define variable filename_type.

3864 Instead of having skeletons declare all valid %define variables and

3867 variable or qualifier is not used by the skeleton in the current
3868 invocation regardless of whether it might sometimes be used by that
3869 skeleton in other invocations. Also, move all %define value macros to
3870 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3871 form, which is replaced by %code.
3872 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

3876 Warn instead of complaining.
3877 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

4168 Discussed starting at

4178 code_props with no code.
4179 (code_props_plain_init, code_props_symbol_action_init,
4180 code_props_rule_action_init, code_props_translate_code): The rest of
4181 the new code_props functional interface. Among other things, the init
4182 functions set the code_props kind field so that
4183 code_props_translate_code will know whether to behave like
4184 translate_symbol_action, translate_rule_action, or translate_code.
4185 These old translate functions must remain until all other modules are

4193 (last_string): New static global similar to the one in scan-gram.l.
4194 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
4195 instead of rule.
4196 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
4197 code_props since Bison may one day use this information for destructors
4198 and printers.
4199 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
4200 (handle_action_dollar): Use symbol_list_n_get and set used flag
4201 directly since symbol_list_n_used_set is removed.
4202 (translate_action): Add a code_props* argument and remove the rule,
4203 action, and location arguments. Pass the code_props* on to code_lex.

4205 Rewrite as wrappers around the new code_props interface.

4423 Encapsulate the push parser state variables into an M4 macro so the
4424 push skeleton doesn't have to list them again for pull mode's yyparse.
4425 For push mode, remove yypush_parse's local equivalents of these
4426 variables to eliminate unnecessary copying between the two sets at
4427 run-time. This patch also fixes at least a bug related to multiple
4428 %initial-action invocations in push mode.

4435 state variables required by push mode.

4438 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
4439 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
4440 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
4441 (yyparse or yypush_parse): For yyparse in pull mode, replace local
4442 parser state variable declarations with
4443 b4_declare_parser_state_variables.
4444 Don't initialize parser state variables when calling yypush_parse since
4445 yypstate_new already does that.
4446 Invoke the user's initial action only upon the first yypush_parse
4447 invocation.
4448 Remove all code that copies between the local parser state variables
4449 and the yypstate.

4603 Fix a couple of bugs related to special characters in user-specified

4624 all_but_ext.
4625 For pkgdatadir muscle, maintain previous functionality by using
4626 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4627 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4628 digraphs would never be expanded. Hopefully no one has M4-special
4629 characters in his Bison installation path.

5496 Whether the default %destructor/%printer applies to a particular symbol
5497 isn't a question of whether the user *declares* that symbol (in %token,
5498 for example). It's a question of whether the user by any means
5499 *defines* the symbol at all (by simply using a char token, for
5500 example). $end is defined by Bison whereas any other token with token
5501 number 0 is defined by the user. The error token is always defined by
5502 Bison regardless of whether the user declares it with %token, but we
5503 may one day let the user define error as a nonterminal instead.

5554 symbol_pack_processor now leaves empty slots in the symbols array.
5555 Remove those slots.

5557 added in previous commit since non-aliased string literals are allowed
5558 again.

5572 don't assign it a symbol number since symbol_make_alias does that.
5573 (symbol_make_alias): It's not necessary to decrement the symbol and
5574 token counts anymore. Don't assume that an alias declaration occurs
5575 before any uses of the identifier or string, and thus don't assert that
5576 one of them has the highest symbol number so far.

6564 Also, the embedded comments in this test case claim it checks the case
6565 of an empty RHS that has inherited the initial location. However, the
6566 corresponding LHS was already resolved, so yyresolveLocations didn't
6567 actually have reason to modify it. Fix this by forcing
6568 nondeterministic operation at the beginning of the parse.

8041 Use unlocked I/O for a minor performance improvement on hosts like

8291 * NEWS: Remove notice of yytname change, since it was never in an
8292 official release.
8293 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
8294 diagnostic.
8295 * src/output.c (prepare): Likewise.
8296 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
8297 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
8298 is not defined. This is an awful hack, but it's enough for now.
8299 All callers changed.
8300 * tests/glr-regression-at (make_value): Args are const pointers now,
8301 to avoid GCC warning.
8302 (Duplicated user destructor for lookahead): New test. Currently
8303 skipped. It fails on my host but I'm not sure it'll always fail.

8492 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
8493 that the byte '\0xff' is not printable in the C locale; it is,
8494 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
8495 not printable, so use '\0x81' to test.

8663 remove trailing spaces. This loses the exit status of ./types,
8664 and isn't needed since ./types shouldn't be emitting trailing
8665 spaces.
8666 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8667 as the stack isn't valid in that case.
8668
8669 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8670 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8671 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):

8673 is used.

8680 overly-picky compilers that reject 'char *foo = "bar";'.
8681
8682 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8683 to FILE * parameter, not to stderr. This fixes a typo introduced
8684 in the 2005-07-12 change.
8685

8698 Destructor cleanups and regularization among the three skeletons.
8699 * NEWS: Document the behavior changes.
8700 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8701 stack before failing, as the cleanup code will do it for us now.
8702 * data/lalr1.cc (yyerrlab): Likewise.
8703 * data/glr.c (yyparse): Pop everything off the stack before
8704 freeing it, so that destructors get called properly.
8705 * data/lalr1.cc (yyreturn): Likewise.
8706 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8707 This is more consistent.
8708 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8709 why destructors might be called. 1.875 -> 2.1.
8710 (Destructor Decl, Decl Summary, Table of Symbols):
8711 Some English-language cleanups for %destructor.

8721 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".

8724 Rename yyoverflowab to yyexhaustedlab.
8725 When memory exhaustion occurs during syntax-error reporting,
8726 report it separately rather than in a single diagnostic; this
8727 eases translation.

8738 can be understood only by someone who can read the
8739 (English-language) source code.
8740
8741 Generate runtime-po/bison-runtime.pot automatically, so that we
8742 don't have to worry about garbage getting in that file. We'll
8743 make sure after the next official release that old msgids don't
8744 get lost. See

8750 Fix typos in explanations of the runtime file.
8751 * bootstrap: Change gettext keyword from YYI18N to YY_.
8752 Use standard Makefile.in.in in runtime-po, since we'll arrange
8753 for backward-compatible bison-runtime.po files in a different way.
8754 * data/glr.c (YY_): New macro, from yacc.c.
8755 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8756 Translate messages intended for users.
8757 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8758 the wording in the other skeletons. We don't know that the memory
8759 is virtual.
8760 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8761 Use same method that yacc.c uses.
8762 Don't translate debugging messages.
8763 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8764 it doesn't work (yet), and requires C++ expertise to fix.
8765 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8766 Move defn to a more logical place, to be consistent with other
8767 skeletons.
8768 Don't translate debugging messages.
8769 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8770 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8771 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8772 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

8791 struct.

8795 if YYABORT is used).

9121 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
9122 conftest*, for benefit of CVS commands run at the same time as
9123 "configure". Add build-aux, since "bootstrap" now creates it and
9124 its subfiles.
9125 * Makefile.cfg (move_if_change): Remove.
9126 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
9127 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

9146 fopen-safer.c, stdio-safer.h, unistd-safer.h.
9147 * lib/subpipe.c: Include "unistd-safer.h".
9148 (create_subpipe): Make sure all the newly-created
9149 file descriptors are > 2, so that diagnostics don't
9150 get sent down them (which might cause Bison to hang, in theory).
9151 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.

9569 some arbitrary limits. It uses more memory but nowadays that's

9976 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9977 whether the reducion was empty or not. This leaves room to
9978 improve the use of YYLLOC_DEFAULT in such a case.
9979 lalr1.cc is still experimental, so changing this is acceptable.
9980 And finally, there are probably not many users who changed the
9981 handling of locations in GLR, so changing is admissible too.

10129 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
10130 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
10131 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
10132 the extra Bison directives instead of the whole series.
10133 Change the grammar so that there are recoverable errors, and
10134 unrecoverable errors. Now we can have the parser give up before
10135 consuming the whole input. As a result we now can observe that
10136 the lookahead is freed when needed.
10137 Change the parser source to parse argv[1] instead of a hard coded
10138 string.
10139 Simplify yylex, and give a value and location to EOF.
10140 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
10141 passed directives already coded in the file.
10142 Add some tests to check the location of "error".
10143 For some tests, the C++ parser is correct, and not yacc.c.
10144 For other tests, they provide different, but unsatisfying, values,
10145 so keep the C++ value so that at least one parser is "correct"
10146 according to the test suite.

10326 Spent a few hours checking out which prerequisite versions the
10327 current sources actually require. I went all the way back to
10328 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
10329 a seemingly endless set of combinations of versions more recent
10330 than that. The bottom line is that the current sources require
10331 fairly recent versions of the build tools, and it'll be some work
10332 to change this.
10333 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.

10848 When reducing initial empty rules, Bison parser read an initial

26ec81e0

11147 The problem was that GLR parsers did not conform to the C standard,
11148 because actions like { $1 = $2 + $3; } expanded to expressions
11149 that invoked YYFILL in separate subexpressions, and YYFILL assigned
11150 to a local variable. The C standard says that expressions
11151 like (var = f ()) + (var = f ()) have undefined behavior.
11152 Another problem was that GCC sometimes issues warnings that
11153 yyfill and its parameters are unused.
11154
11155 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
11156 as possibly unused.
11157 (yyfill): New function.
11158 (YYFILL): Use it.
11159 (yyuserAction): Change type of yynormal to bool, so that it matches
11160 the new yyfill signature. Mark it as possibly unused.
11161
11162
11163 Follow up on a bug I reported in February, where a Bison-generated
11164 parser can loop. Provide a test case and a fix for yacc.c. I
11165 don't have a fix for lalr1.cc or for glr.c, unfortunately.
11166 The original bug report is in:

11169 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
11170 macro's size was becoming unwieldy.
11171 (yyerrlab): Do not discard an empty lookahead symbol, as this
11172 might destroy garbage.
11173 (yyerrorlab): New label, with the old contents of YYERROR,
11174 plus the following change: pop the stack of rhs corresponding
11175 to the production that invoked YYERROR. That is how Yacc
11176 behaves, and POSIX requires this behavior.
11177 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
11178 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
11179 Define 'alarm' to do nothing if unistd.h is not available.
11180 Add a new rule "exp: '-' error;" to test the above change to
11181 data/yacc.c. Use 'alarm' to abort any test taking longer than
11182 10 seconds, as it's probably looping.
11183 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
11184 Also, the new yacc.c generates two fewer diagnostics for an
11185 existing test.

11835 popped). This means that the initial elements will not be freed

11837 these elements have fake values.

11977 onto yylerrsp so that we don't lose track of the error's end.
11978 (yyerrlab1): Now is only the target of YYERROR, so that we can
11979 properly record the location of the action that failed. For GCC
11980 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11981 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11982 (yyerrlab2): New label, which yyerrlab now falls through to.
11983 Compute the error's location by applying YYLLOC_DEFAULT to
11984 the locations of all the symbols that went into the error.
11985 * doc/bison.texinfo (Location Default Action): Mention that
11986 YYLLOC_DEFAULT is also invoked for syntax errors.
11987 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11988 Error locations include the locations of all the tokens that were
11989 discarded, not just the last token.

12046 If the user does not define YYSTYPE as a macro, Bison now declares it
12047 using typedef instead of defining it as a macro. POSIX requires this.
12048 For consistency, YYLTYPE is also declared instead of defined.
12049
12050 %union directives can now have a tag before the `{', e.g., the
12051 directive `%union foo {...}' now generates the C code
12052 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
12053 The default union tag is `YYSTYPE', for compatibility with Solaris 9
12054 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
12055 instead of `yyltype'.
12056
12057 `yystype' and `yyltype' are now obsolescent macros instead of being
12058 typedefs or tags; they are no longer documented and will be
12059 withdrawn in a future release.

12067 for backward compatibility.

12069

12091 has (or usually has) an immediately-following braced code.

12093 to return when scanning braced code.

12163 Remove unportable casts and storage allocation tricks.
12164 While we're at it, remove almost all casts, since they

12168
12169 * src/derives.c (derives_compute): Do not subtract NTOKENS from
12170 the pointer DSET returned by malloc; this isn't portable.
12171 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
12172 Similarly for DERIVES.

12181 rather than XMALLOC (char, N).

12199 where it's needed.

12224
12225 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
12226 var instead of casting to long, to avoid casts.
12227 (prepare_states): Use MALLOC rather than alloca, so that we don't
12228 have to worry about alloca.

12235 STATE_ALLOC): Remove.

12237 rather than calloc, and use offsetof to avoid allocating slightly
12238 too much storage.
12239 (state_new): Initialize all members.

12261 (table_grow, table_ninf_remap): Use signed table size.

12264 * src/uniqstr.c (hash_compare_uniqstr): Likewise.

13102 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
13103 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
13104 Use new escapes @{ and @} for [ and ].
13105
13106 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
13107 them with auto vars.
13108 Switch to new escape scheme, where @ is the escape character uniformly.
13109 Abort if a stray escape character is found. Avoid unbounded input
13110 buffer when parsing non-escaped text.

13125 counted in the token inserted at end of file. Now takes
13126 location_t *, not location_t, so that the location can be
13127 adjusted. All uses changed.

13841 Let nondeterministic skeletons be usable with deterministic
13842 tables.
13843
13844 With the patch, GAWK compiled by GCC without -O2 passes its test
13845 suite using a GLR parser driven by LALR tables. It fails with -O2
13846 because `struct stat' gives two different answers on my machine:
13847 88 (definition of an auto var) and later 96 (memset on this var).
13848 Hence the stack is badly corrumpted. The headers inclusion is to
13849 blame: if I move the awk.h inclusion before GLR's system header
13850 inclusion, the two struct stat have the same size.

14324 functions are not portable. Do not assume size_t is the
14325 same width as int.
14326 (yypstates): Do not assume that ptrdiff_t is the same width
14327 as int, and similarly for yyposn and YYINDEX.
14328

14369 PROTOTYPES to check for prototypes, and "defined __STDC__" to
14370 check for void *.
14371
14372 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
14373 size_t; the old version tried to do this but casted improperly.
14374 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
14375 (bitset_test): Now returns int, not unsigned long.
14376

14378 (_): New macro.
14379 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't

14406 lib/timevar.c.
14407 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
14408 manual recommends.
14409 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
14410
14411 * src/complain.c (strerror_r): Remove decl; not needed.
14412 (strerror): Use same pattern as ../lib/error.c.
14413
14414 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
14415

14417
14418 * src/main.c (main): Cast result of bindtextdomain and textdomain
14419 to void, to avoid a GCC warning when --disable-nls is in effect.
14420
14421 * src/scan-gram.l: Use strings rather than escapes when possible,
14422 to minimize the number of warnings from xgettext.
14423 (handle_action_dollar, handle_action_at): Don't use isdigit,
14424 as it mishandles negative chars and it may not work as expected
14425 outside the C locale.
14426
14427 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
14428 this is a GCC extension and is not portable to other compilers.
14429
14430 * src/system.h (alloca): Use same pattern as ../lib/error.c.
14431 Do not include <ctype.h>; no longer needed.
14432 Do not include <malloc.h>; no longer needed (and generates
14433 warnings on OpenBSD 3.0).
14434
14435 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
14436 it's not portable.
14437
14438 * tests/regression.at: Do not use 'cc -c input.c -o input';
14439 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
14440
14441 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
14442 exit status as failure, not just exit status 1. Sun C exits
14443 with status 2 sometimes.
14444
14445 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
14446 Use it for the two large tests.

14610 different: save its reduction (accept) instead of having a state
14611 without any action (no shift or goto, no reduce).
14612 Note: the final state is now a ``regular'' state, i.e., the
14613 parsers now contain `reduce 0' as default reduction.
14614 Nevertheless, since they decide to `accept' when yystate =
14615 final_state, they still will not reduce rule 0.

17295 problems: because Flex includes the headers *before* us,
17296 _GNU_SOURCE is not defined by config.h, and therefore strndup was
17297 not visible.

17315 Don't use %option yylineno: it seems that then Flex imagines
17316 REJECT has been used, and therefore it won't reallocate its
17317 buffers (which makes no other sense to me than a bug). It results
17318 in warnings for `unused: yy_flex_realloc'.

17663 Be sure to preserve the value of the eoftoken.
17664 (reader): Make sure eoftoken is defined.

17762 the switch/case/break flesh.
17763 Don't parse the user action that might follow the guard, let...

17809 As much as possible, depend upon nlookaheads, instead of the
17810 `lookaheadsp' member of the following state (since lookaheads of
17811 successive states are successive, the difference between state n + 1

18511 Because useless nonterminals are now kept alive (instead of being
18512 `destroyed'), we now sometimes examine them, and store information
18513 related to them. Hence we need to know their number, and adjust
18514 memory allocations.

18516 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
18517 static.
18518 * src/LR0.c (allocate_itemsets): The memory allocated to
18519 `symbol_count' was used for two different purpose: once to count
18520 the number of occurrences of each symbol, and later reassigned to
18521 `shift_symbol', containing the symbol that can be shifted from a
18522 given state.
18523 Deobfuscate, i.e., allocate, use and free `symbol_count' here
18524 only, and...
18525 (new_itemsets): Allocate `shift_symbol' here.
18526 (allocate_itemsets): symbol_count includes useless nonterminals.
18527 Make room for them.
18528 (free_storage): Use `free', not `XFREE', for pointers that cannot
18529 be null.

18671
18672 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18673 a parser stack overflow. Allocate just one block of memory for all
18674 three stacks, instead of allocating three blocks; this typically is
18675 faster and reduces fragmentation.

18677 Do not limit the number of items in the stack to a value that fits

20907 The location tracking mechanism is precious for parse error
20908 messages. Nevertheless, it is enabled only when `@n' is used in
20909 the grammar, which is a different issue (you can use it in error
20910 message, but not in the grammar per se). Therefore, there should
20911 be another means to enable it.

20943 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20944 the latter demonstrates a flaw in the handling of non debugging
20945 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20946 was used in order to simplify:
20947
20948 #if YYDEBUG
20949 if (yydebug)
20950 {
20951 ...
20952 }
20953 #endif

20955 into
20956
20957 if (yydebug)
20958 {
20959 ...
20960 }
20961
20962 unfortunately this leads to a CPP conflict when
20963 `--name-prefix=foo' is used since it produces `#define yydebug
20964 foodebug'.

21014 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
21015 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
21016 difficult and introduced a lot of core dump. It turns out that
21017 Bison used an implementation of `xmalloc' based on `calloc', and
21018 at various places it does depend upon the initialization to 0. I
21019 have not tried to isolate the pertinent places, and all the former
21020 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

22158 way to specify the flags -n, -l, and -r. Also added hooks for
