3 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
4 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
5 Summary" not "Directives".
6 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
7 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
8 since the former is now the more complete one.
9 (Prologue Alternatives): Likewise and do the same for %defines.
10 (Table of Symbols): Add summary of %code, add summary of %define, and
11 move full %code documentation to...
12 (Decl Summary): ... here for consistency with other entries in these
13 sections.
14 Move %define entry in order to keep this list alphabetized.
15 Reword %define entry a little to put less emphasis on the skeleton
16 concept, which most users shouldn't have to think about.

23 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
24 * src/system.h: Don't include <stpcpy.h>; this is now done by
25 <string.h>.

47 Discussed starting at
48 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
49 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
50 (Bison Options): Document in --skeleton entry.
51 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
52 full_skeleton can't necessarily hold all of pkgdatadir.
53 If the specified skeleton file name contains a `/', don't prepend
54 pkgdatadir.
55 * src/parse-gram.y (prologue_declaration): If the specified skeleton
56 file name contains a `/', prepend the grammar file directory.

101
102 Clean up %define and %code implementation in M4 some. Most
103 importantly, rename all related macros to be in the b4_percent_define
104 and b4_percent_code namespaces. Also, complete support for `.' in
105 %define variable names and %code qualifiers.
106 * data/bison.m4 (b4_check_user_names): Check for special
107 "SKELETON-NAMESPACE(name)" macros instead of using two nested
108 m4_foreach loops.
109 (b4_get_percent_define, b4_get_percent_code): Rename to...
110 (b4_percent_define_get, b4_percent_code_get): ... these.
111 Extend documentation with examples.
112 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
113 b4_percent_define_skeleton_variables and
114 b4_percent_code_skeleton_qualifiers.
115 Expect any value for the %define variable `foo' to be stored in the
116 macro named `b4_percent_define(foo)'; expect any %code blocks for the
117 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
118 expect any unqualified %code blocks to be stored in a macro named
119 `b4_percent_code_unqualified'.
120 Use m4_indir so that %define variable names and %code qualifiers can
121 contain `.', which is allowed by the grammar parser.
122 (b4_percent_define_default): New macro to set a default value for a
123 %define variable.
124 (m4_wrap): Update wrapped code, and fix some underquoting.
125 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
126 Expect grammar uses of %define variables and %code qualifiers to be
127 defined in b4_percent_define_user_variables and
128 b4_percent_code_user_qualifiers.
129 * data/c++.m4: Use b4_percent_define_default rather than
130 m4_define_default. Fix some underquoting. Skeleton usage of %define
131 variable define_location_comparison now implies skeleton usage of
132 %define variable filename_type.
133 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
134 data/push.c, data/yacc.c: Update macro names.
135 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
136 muscle names.

157 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
158 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
159 miss Valgrind messages.

175 Simplify union and prologue handling, and escape union and lex/parse
176 params with digraphs.
177 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
178 values to the empty string since these are no longer guaranteed
179 initialized by the front-end.
180 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
181 braces around b4_user_stype since this is no longer done by the
182 front-end.
183 * src/files.c, src/files.h (pre_prologue_obstack,
184 post_prologue_obstack): Remove.
185 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
186 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
187 with digraphs. This fixes lex params and parse params.
188 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
189 * src/output.c (prepare): Remove muscle insertion of the prologues.
190 (output): Remove freeing of pre_prologue_obstack and
191 post_prologue_obstack.
192 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
193 than prologue_augment for prologue parsing so you don't need prologue
194 obstacks.
5c80250c

209 allowed in them to M4-friendly ones. For %define, continue to support
210 the quoted form as a deprecated feature. Discussed starting at
211 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.

213 %code.
214 * doc/bison.texinfo (Prologue Alternatives): Update.
215 (Bison Declaration Summary): In %defines entry, update mention of
216 `%code requires' and `%code provides'.
217 (C++ Location Values): Update %define uses.
218 (Calc++ Parser Interface): Likewise.

224 `STRING'.
225 (variable): New nonterminal that takes an `ID' or a `STRING'.
226 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
227 and %define uses.
228 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.

241 Instead of having skeletons declare all valid %define variables and
242 %code qualifiers, provide macros that retrieve the associated values
243 and build these lists automatically. Thus Bison will now warn when a
244 variable or qualifier is not used by the skeleton in the current
245 invocation regardless of whether it might sometimes be used by that
246 skeleton in other invocations. Also, move all %define value macros to
247 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
248 form, which is replaced by %code.
249 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
250 (b4_check_user_names): ... this, and change the series of valid name
251 arguments to a single list argument for names used in the skeleton
252 similar to the existing list argument for names used in the grammar.
253 Warn instead of complaining.
254 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
255 values and %code code, to format %code code properly, and to build
256 lists of all %define variables and %code qualifiers used in the
257 skeleton: b4_skeleton_percent_define_variables and
258 b4_skeleton_percent_code_qualifiers.
259 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
260 Remove, and...
261 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
262 the skeleton names lists can finish building first. In place of
263 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
264 expect the lists b4_user_percent_define_variables and
265 b4_user_percent_code_qualifiers.
266 * data/c++.m4: Where setting default values for b4_parser_class_name,
267 b4_location_type, b4_filename_type, b4_namespace, and
268 b4_define_location_comparison, update their names to the
269 b4_percent_define_ namespace.
270 * data/glr.c: Don't use b4_check_percent_define_variables and
271 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
272 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
273 (b4_parser_class_name, b4_namespace): Define these using
a4e25e1d 274 b4_get_percent_define for parser_class_name and namespace.
6afc30cc
JD
275 * data/location.cc: Use b4_get_percent_define.
276 * data/push.c: Don't use b4_check_percent_define_variables and
277 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
278 * data/yacc.c: Likewise, and don't call m4_exit in
279 b4_use_push_for_pull_if or m4_wrap code will never execute.
280 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
281 Rename to...
282 (muscle_grow_user_name_list): ... this for consistency with the
283 terminology used in bison.m4.
284 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
285 %define variable names, and rename muscle used_percent_define_variables
286 to user_percent_define_variables.
287 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
288 user_percent_code_qualifiers.
289 (content): Remove.
290 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
291 {CODE} form is no longer accepted.
292 * tests/input.at (Reject bad %code qualifiers): Rename to...
293 (Reject unused %code qualifiers): ... this, and update test output.
294 (%define error): Update test output.

298 Check for unrecognized %define variables similar to checking for
299 unrecognized %code qualifiers. Check for redefined %define variables.
300 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
301 generalizes...
302 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
303 (b4_check_percent_define_variables): New, also wraps it.
304 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
305 variables using b4_check_percent_define_variables.
306 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
307 all those exercised in the test suite and all those listed in the
308 `Default values' section of c++.m4. Are there others?
309 * data/push.c, data/yacc.c: Declare no valid %define variables.
310 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
311 similar to muscle_find, but it works even when the muscle stores a
312 const value.
313 (muscle_grow_used_name_list): New function for constructing the used
314 name list muscles that b4_check_for_unrecognized_names requires.
315 * src/parse-gram.y (prologue_declaration): Warn if a variable is
316 %define'd more than once. Define the b4_used_percent_define_variables
317 muscle with muscle_grow_used_name_list.
318 (grammar_declaration): Abbreviate %code code with
319 muscle_grow_used_name_list.

326 * data/bison.m4 (b4_error_at): New, invoked by...
327 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
328 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
329 @fatal_at(...@) directives.
330 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
331 qualifiers in b4_used_percent_code_qualifiers and to use
332 b4_complain_at.
333 * src/location.c, src/location.h (boundary_set_from_string): New global
334 function.
335 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
336 function.
337 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers

340 function.
341 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
342 (lineno): Rename to...
343 (out_lineno): ... this so I don't misunderstand it again.
344 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
345 here; these newlines are in the input but not the output file.
346 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
347 (at_directive_perform): ... this new static function, and add handling
348 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
349 directives.

367 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
368 unreliable -- especially when they're hidden inside another macro.
369 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
370 data/c.m4: Remove m4_divert(-1).
371 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
372 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
373 m4_divert_push(0) and m4_divert_pop(0).
279cabb6 374 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
08af01c2

375 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
376 pushed and popped by m4sugar, should be first on the stack.
377
378 Provide warn, complain, and fatal function callbacks to the skeletons.
379 This provides more flexibility than m4_fatal, improves the error
380 message format, and captures messages for translation. Discussed
381 starting at
382 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
383 * data/bison.m4 (b4_error): New, invoked by...
384 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
385 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
386 directives. Because these M4 macros might be called when the current
387 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
388 the previous removal of uses of m4_divert, which caused trouble.
389 (b4_check_percent_code_qualifiers): Use b4_complain instead of
390 m4_fatal to report unrecognized %code qualifiers.
391 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
392 push parser requests.
393 * data/glr.c: Use b4_complain instead of m4_fatal to report

541 Encapsulate code properties and related functionality for the various
542 destructors, printers, and actions into a code_props structure and
543 interface. This patch merely implements code_props in scan-code.h and
544 scan-code.l. Future patches will rewrite other modules to use it.
545 Discussed starting at
546 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
547 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
548 consistently initialize const structs that have an empty location
549 field.
550 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
551 to ensure consistency.
552 * src/scan-code.h (code_props): New structure.
553 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
554 function, macro, and const global variable for initializing a
555 code_props with no code.
556 (code_props_plain_init, code_props_symbol_action_init,
557 code_props_rule_action_init, code_props_translate_code): The rest of
558 the new code_props functional interface. Among other things, the init
559 functions set the code_props kind field so that
560 code_props_translate_code will know whether to behave like
561 translate_symbol_action, translate_rule_action, or translate_code.
562 These old translate functions must remain until all other modules are
563 updated to use the new code_props interface.
564 (code_scanner_last_string_free): New function similar to
565 gram_scanner_last_string_free.
566 (code_scanner_free): Add documentation.
567 * src/scan-code.l: Implement the new interface.
568 (code_lex): Make it static, add a code_props* argument, and remove the
569 rule argument.
570 (last_string): New static global similar to the one in scan-gram.l.
571 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
572 instead of rule.
573 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
574 code_props since Bison may one day use this information for destructors
575 and printers.
576 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
577 (handle_action_dollar): Use symbol_list_n_get and set used flag
578 directly since symbol_list_n_used_set is removed.
579 (translate_action): Add a code_props* argument and remove the rule,
580 action, and location arguments. Pass the code_props* on to code_lex.
581 (translate_rule_action, translate_symbol_action, translate_code):
582 Rewrite as wrappers around the new code_props interface.
583 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
584 it would eventually need to break the encapsulation of code_props.

800 Encapsulate the push parser state variables into an M4 macro so the
801 push skeleton doesn't have to list them again for pull mode's yyparse.
802 For push mode, remove yypush_parse's local equivalents of these
803 variables to eliminate unnecessary copying between the two sets at
804 run-time. This patch also fixes at least a bug related to multiple
805 %initial-action invocations in push mode.

815 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
816 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
817 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
818 (yyparse or yypush_parse): For yyparse in pull mode, replace local
819 parser state variable declarations with
820 b4_declare_parser_state_variables.
821 Don't initialize parser state variables when calling yypush_parse since
822 yypstate_new already does that.
823 Invoke the user's initial action only upon the first yypush_parse
824 invocation.

826 and the yypstate.

1002 For pkgdatadir muscle, maintain previous functionality by using
1003 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
1004 is that b4_pkgdatadir is used inside m4_include in the skeletons, so

1173 * src/files.c (tr): Change return type to void.
1174 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
1175 has been called previously for the same key.
1176 (muscle_find): Return storage instead of value so that
1177 --enable-gcc-warnings doesn't produce warnings that the return discards
1178 const. aver that the value and storage are the same since storage
1179 could potentially be NULL when value is not.

1195 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):

1197 since they are freed.

1218 and add a new storage member that is char * and can be freed.
1219 (muscle_entry_free): New private function.

1225 add a new `char *code' member.

1227 * src/scan-code.h (translate_rule_action):
1228 (translate_symbol_action, translate_code, translate_action): Return
1229 `char const *' rather than `char *' since external code should not free
1230 these strings.
1231 * src/scan-code.l: Likewise.

1239 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
1240 expecting a non-zero exit status sets --leak-check=summary and
1241 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
1242 this case, and we don't want to hear about it.

1873 Whether the default %destructor/%printer applies to a particular symbol
1874 isn't a question of whether the user *declares* that symbol (in %token,
1875 for example). It's a question of whether the user by any means
1876 *defines* the symbol at all (by simply using a char token, for
1877 example). $end is defined by Bison whereas any other token with token
1878 number 0 is defined by the user. The error token is always defined by
1879 Bison regardless of whether the user declares it with %token, but we
1880 may one day let the user define error as a nonterminal instead.

1948 (symbol_class_set): Don't count a string literal as a new token, and
1949 don't assign it a symbol number since symbol_make_alias does that.
1950 (symbol_make_alias): It's not necessary to decrement the symbol and
1951 token counts anymore. Don't assume that an alias declaration occurs
1952 before any uses of the identifier or string, and thus don't assert that
1953 one of them has the highest symbol number so far.
1954 (symbol_check_alias_consistency): Complain if there's a string literal
1955 that wasn't declared as an alias.

2945 actually have reason to modify it. Fix this by forcing
2946 nondeterministic operation at the beginning of the parse.

4419 Use unlocked I/O for a minor performance improvement on hosts like

4670 official release.
4671 * data/glr.c (yydestroyGLRState): Rename local var to avoid shadowing
4672 diagnostic.
4673 * src/output.c (prepare): Likewise.
4674 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
4675 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
4676 is not defined. This is an awful hack, but it's enough for now.
4677 All callers changed.
4678 * tests/glr-regression-at (make_value): Args are const pointers now,
4679 to avoid GCC warning.
4680 (Duplicated user destructor for lookahead): New test. Currently
4681 skipped. It fails on my host but I'm not sure it'll always fail.

4704 (yyreport_syntax_error_): Remove, replaced by...
4705 (yysyntax_error_): this which returns a string and leaves to the
4706 caller the call to the users' error function.
4707 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
4708 Move from members of the parser object...

4740 contains obsolete information and isn't worth distributing as a
4741 separate file anyway.
4742 * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
4743 (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

4870 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
4871 that the byte '\0xff' is not printable in the C locale; it is,
4872 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
4873 not printable, so use '\0x81' to test.

4930 it's error-prone and "make maintainer-distcheck" rejects it.

5032 the 2005-04-17 change, which is now accomplished (mostly) via
5033 changes in the parsers as described above.

5043 spaces.
5044 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,

5076 Destructor cleanups and regularization among the three skeletons.
5077 * NEWS: Document the behavior changes.
5078 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
5079 stack before failing, as the cleanup code will do it for us now.
5080 * data/lalr1.cc (yyerrlab): Likewise.
5081 * data/glr.c (yyparse): Pop everything off the stack before
5082 freeing it, so that destructors get called properly.
5083 * data/lalr1.cc (yyreturn): Likewise.
5084 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
5085 This is more consistent.

5116 can be understood only by someone who can read the
5117 (English-language) source code.
5118
5119 Generate runtime-po/bison-runtime.pot automatically, so that we
5120 don't have to worry about garbage getting in that file. We'll
5121 make sure after the next official release that old msgids don't

5128 Fix typos in explanations of the runtime file.
5129 * bootstrap: Change gettext keyword from YYI18N to YY_.
5130 Use standard Makefile.in.in in runtime-po, since we'll arrange
5131 for backward-compatible bison-runtime.po files in a different way.
5132 * data/glr.c (YY_): New macro, from yacc.c.
5133 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
5134 Translate messages intended for users.
5135 (yyreportSyntaxError): Change "virtual memory" to "memory" to match

5137 is virtual.

5139 Use same method that yacc.c uses.
5140 Don't translate debugging messages.

5144 Move defn to a more logical place, to be consistent with other
5145 skeletons.
5146 Don't translate debugging messages.
5147 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
5148 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
5149 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
5150 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

5464 (YYMALLOC, YYFREE): Define only if needed.

5498 Various maintainer cleanups.
5499 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
5500 conftest*, for benefit of CVS commands run at the same time as
5501 "configure". Add build-aux, since "bootstrap" now creates it and
5502 its subfiles.
5503 * Makefile.cfg (move_if_change): Remove.
5504 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
5505 (ftp-gnu, www-gnu, move_if_change, local_updates, update):

5524 fopen-safer.c, stdio-safer.h, unistd-safer.h.
5525 * lib/subpipe.c: Include "unistd-safer.h".
5526 (create_subpipe): Make sure all the newly-created
5527 file descriptors are > 2, so that diagnostics don't
5528 get sent down them (which might cause Bison to hang, in theory).
5529 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.

5947 some arbitrary limits. It uses more memory but nowadays that's
5948 not much of an issue.

6354 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
6355 whether the reducion was empty or not. This leaves room to
6356 improve the use of YYLLOC_DEFAULT in such a case.
6357 lalr1.cc is still experimental, so changing this is acceptable.
6358 And finally, there are probably not many users who changed the
6359 handling of locations in GLR, so changing is admissible too.

6509 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
6510 the extra Bison directives instead of the whole series.
6511 Change the grammar so that there are recoverable errors, and
6512 unrecoverable errors. Now we can have the parser give up before
6513 consuming the whole input. As a result we now can observe that
6514 the lookahead is freed when needed.
6515 Change the parser source to parse argv[1] instead of a hard coded
6516 string.
6517 Simplify yylex, and give a value and location to EOF.
6518 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
6519 passed directives already coded in the file.
6520 Add some tests to check the location of "error".
6521 For some tests, the C++ parser is correct, and not yacc.c.
6522 For other tests, they provide different, but unsatisfying, values,
6523 so keep the C++ value so that at least one parser is "correct"
6524 according to the test suite.

6704 Spent a few hours checking out which prerequisite versions the
6705 current sources actually require. I went all the way back to
6706 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
6707 a seemingly endless set of combinations of versions more recent
6708 than that. The bottom line is that the current sources require
6709 fairly recent versions of the build tools, and it'll be some work
6710 to change this.

7523 Fix a GLR parser bug I reported in February; see

7525 The problem was that GLR parsers did not conform to the C standard,
7526 because actions like { $1 = $2 + $3; } expanded to expressions
7527 that invoked YYFILL in separate subexpressions, and YYFILL assigned
7528 to a local variable. The C standard says that expressions
7529 like (var = f ()) + (var = f ()) have undefined behavior.
7530 Another problem was that GCC sometimes issues warnings that
7531 yyfill and its parameters are unused.
7532
7533 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
7534 as possibly unused.
7535 (yyfill): New function.
7536 (YYFILL): Use it.
7537 (yyuserAction): Change type of yynormal to bool, so that it matches
7538 the new yyfill signature. Mark it as possibly unused.
7539
7540
7541 Follow up on a bug I reported in February, where a Bison-generated
7542 parser can loop. Provide a test case and a fix for yacc.c. I
7543 don't have a fix for lalr1.cc or for glr.c, unfortunately.
7544 The original bug report is in:

7546
7547 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
7548 macro's size was becoming unwieldy.
7549 (yyerrlab): Do not discard an empty lookahead symbol, as this
7550 might destroy garbage.
7551 (yyerrorlab): New label, with the old contents of YYERROR,
7552 plus the following change: pop the stack of rhs corresponding
7553 to the production that invoked YYERROR. That is how Yacc
7554 behaves, and POSIX requires this behavior.
7555 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
7556 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
7557 Define 'alarm' to do nothing if unistd.h is not available.
7558 Add a new rule "exp: '-' error;" to test the above change to
7559 data/yacc.c. Use 'alarm' to abort any test taking longer than
7560 10 seconds, as it's probably looping.
7561 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
7562 Also, the new yacc.c generates two fewer diagnostics for an
7563 existing test.

7725 Declare to be of type suitable for the ninf value itself, not of
7726 type suitable for the corresponding table, since the latter might
7727 be unsigned but the ninf value might be negative. This fixes a

7753 of a POSIX-compatibility bug in flex 2.5.31.

8191 we don't need to worry about yyerrlab1 being reported as an
8192 "unused label" by non-GCC C compilers. The downside is that if
8193 locations are used then a couple of statements are duplicated each
8194 time YYERROR is invoked, but the upside is that the warnings
8195 should vanish.
8196 (yyerrlab1): Move code to YERROR.

8210 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
8211 when the stacks contain one element, as the loop would otherwise
8212 free the last state, and then use the top state (the one we just
8213 popped). This means that the initial elements will not be freed
8214 explicitly, as is the case in yacc.c; it is not a problem, as
8215 these elements have fake values.

8328 'conflict_report'. Translate the entire conflict report at once,
8329 so that we don't assume that "," has the same interpretation in
8330 all languages.
8331 (conflicts_output): Use Yacc-style conflict report for each state,
8332 instead of our more-complicated style.

8334 the input file name when not emulating Yacc.
8335 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted

8352 * data/yacc.c (yyparse): New local var yylerrsp, to record the
8353 top of the location stack's error locations.
8354 (yyerrlab): Set it. When discarding a token, push its location
8355 onto yylerrsp so that we don't lose track of the error's end.
8356 (yyerrlab1): Now is only the target of YYERROR, so that we can
8357 properly record the location of the action that failed. For GCC
8358 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
8359 GCC warning about yyerrlab1 being unused if YYERROR is unused.
8360 (yyerrlab2): New label, which yyerrlab now falls through to.
8361 Compute the error's location by applying YYLLOC_DEFAULT to
8362 the locations of all the symbols that went into the error.
8363 * doc/bison.texinfo (Location Default Action): Mention that
8364 YYLLOC_DEFAULT is also invoked for syntax errors.
8365 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

8424 If the user does not define YYSTYPE as a macro, Bison now declares it
8425 using typedef instead of defining it as a macro. POSIX requires this.
8426 For consistency, YYLTYPE is also declared instead of defined.
8427
8428 %union directives can now have a tag before the `{', e.g., the
8429 directive `%union foo {...}' now generates the C code
8430 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
8431 The default union tag is `YYSTYPE', for compatibility with Solaris 9
8432 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
8433 instead of `yyltype'.
8434
8435 `yystype' and `yyltype' are now obsolescent macros instead of being
8436 typedefs or tags; they are no longer documented and will be
8437 withdrawn in a future release.

8444 (yyltype, yystype): New (and obsolescent) macros,
8445 for backward compatibility.
8446 * data/yacc.c: Likewise.
8447
8448 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
8449 does not specify a union tag. This is for compatibility with
8450 Solaris 9 yacc.

8455 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,

8540
8541 Remove unportable casts and storage allocation tricks.
8542 While we're at it, remove almost all casts, since they
8543 usually aren't needed and are a sign of trouble.
8544
8545 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
8546
8547 * src/derives.c (derives_compute): Do not subtract NTOKENS from
8548 the pointer DSET returned by malloc; this isn't portable.
8549 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
8550 Similarly for DERIVES.
8551 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
8552 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
8553 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
8554
8555 * src/derives.c (derives_compute): Do not bother invoking
8556 int_of_rule_number, since rule numbers are integers.
8557
8558 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
8559 rather than XMALLOC (char, N).
8560

8562
8563 * src/gram.h (symbol_number_as_item_number,
8564 item_number_as_symbol_number, rule_number_as_item_number,
8565 item_number_as_rule_number):
8566 Now inline functions rather than macros, to avoid casts.
8567 * src/state.h (state_number_as_int): Likewise.

8572
8573 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
8574 since the resulting storage is always stored into.
8575
8576 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
8577 where it's needed.
8578
8579 * src/muscle_tab.c (muscle_m4_output):
8580 Now inline. Return bool, not int.
8581 * src/state.c (state_compare): Likewise.

8594 * src/uniqstr.c (uniqstr_print_processor): Likewise.
8595 * src/muscle_tab.c (muscles_m4_output):
8596 Use new functions instead of casting old functions unportably.

8599 symbols_token_translations_init):

8601 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
8602
8603 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
8604 var instead of casting to long, to avoid casts.
8605 (prepare_states): Use MALLOC rather than alloca, so that we don't
8606 have to worry about alloca.
8607 * src/state.c (state_hash_lookup): Likewise.
8608
8609 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
8610 local var instead of casting to unsigned char, to avoid casts.

8613 STATE_ALLOC): Remove.
8614 (transitions_new, errs_new, reductions_new, state_new): Use malloc
8615 rather than calloc, and use offsetof to avoid allocating slightly
8616 too much storage.
8617 (state_new): Initialize all members.
8618
8619 * src/state.c (state_hash): Use unsigned accumulator, not signed.
8620
8621 * src/symtab.c (symbol_free): Remove; unused.

8634 (CALLOC, MALLOC, REALLOC): New macros.

8660 turn was just renamed from struniq_t.

9430 Use new @ escapes consistently. Represent brackets with @{ and @}
9431 rather than @<:@ and @:>@, since this works a bit better with dumb
9432 editors like vi. Represent @ with @@, since @ is now consistently
9433 an escape. Use @oline@ and @ofile@ rather than __oline__ and
9434 __ofile__, to avoid unexpected expansions. Similarly, use @output
9435 rather than #output.
9436
9437 * data/c.m4 (b4_copyright): Omit file name from comment, since
9438 the file name could contain "*/".
9439 (b4_synclines_flag): Don't quote the 2nd argument; it should already
9440 be quoted. All uses changed.
9441
9442 * data/glr.c: Use new @ escapes consistently.
9443 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
9444 b4_output_header_suffix, b4_output_header_name, b4_header_guard):

9451 * src/files.h: Likewise.
9452
9453 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
9454 mishandled funny characters in file names, and anyway it isn't
9455 needed any more.
9456 * data/yacc.c: Likewise.
9457 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.

9460 * data/yacc.c: Likewise.

9463 strings now.

9466 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
9467 * src/output.c (escaped_file_name_output): New function.
9468 (prepare_symbols): Quote tokens for M4.
9469 (prepare): Don't insert output_infix, output_prefix,
9470 output_parser_name, output_header_name; this is now down by scan-skel.
9471 Insert skeleton as a C string.
9472
9473 * src/output.c (user_actions_output, symbol_destructors_output,
9474 symbol_printers_output): Quote filenames for C and M4.
9475 * src/reader.c (prologue_augment, epilogue_set): Likewise.
9476
9477 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
9478 escapes other than \\ and \'; this simplifies the code.
9479 (<SC_STRING>): Likewise, for \\ and \".
9480 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
9481 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
9482 Use new escapes @{ and @} for [ and ].
9483
9484 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
9485 them with auto vars.
9486 Switch to new escape scheme, where @ is the escape character uniformly.
9487 Abort if a stray escape character is found. Avoid unbounded input
9488 buffer when parsing non-escaped text.
9489
9490 * tests/input.at (Torturing the Scanner): Add tests that @oline@,

9498 evaluate to 0 if it's impossible for NINF to be in the respective
9499 table.
9500 (yygetLRActions, yyrecoverParseError): Use them.
9501
9502 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
9503 counted in the token inserted at end of file. Now takes
9504 location_t *, not location_t, so that the location can be
9505 adjusted. All uses changed.
9506
9507 * tests/regression.at (Invalid inputs): Adjust wording in
9508 diagnostic to match the new behavior.

9511 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
9512 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
9513 abort ();'. This reduces the runtime of the "Many lookaheads"
9514 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

9523 stack, since the stack was never deeper than 1; instead, use the
9524 new auto var c_context to record the stacked value.
9525
9526 Remove nounput option. At an unexpected end of file, we now unput

9709
9710 Handle backslash-newline correctly in C code.
9711 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.

9715 Use {splice} wherever C allows backslash-newline.
9716 YY_STEP after space, newline, vertical-tab.

9722 overflow.
9e32add8 9723
b02d90a5
PE
9724 (YY_STEP): Omit trailing semicolon, so that it's more like C.
9725
9726 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
9727 as well as \000. Check for UCHAR_MAX, not 255.
9728 Allow \x with an arbitrary positive number of digits, as in C.
9729 Check for overflow here.
9730 Allow \? and UCNs, for compatibility with C.
9731
9732 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
9733 with quote slot used by complain_at.
9734
9735 * tests/input.at: Add tests for backslash-newline, m4 quotes
9736 in symbols, long literals, and funny escapes in strings.
9737
9738 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
9739 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.

9750 no longer used.

9774 indicates one.
9775 * src/output.c (output_skeleton): Use xfclose rather than fclose
9776 and ferror. xfclose now checks ferror.
9777
9778 * data/glr.c (YYLEFTMOST_STATE): Remove.
9779 (yyreportTree): Use a stack-based leftmost state. This avoids
9780 our continuing battles with bogus warnings about initializers.

9797 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
9798 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
9799 we use malloc. Don't assume 'A' through 'Z' are contiguous.
9800 Don't assume strdup exists; POSIX says its an XSI extension.

9805 * src/output.c (output_skeleton): Don't disable M4sugar comments

9813 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
9814 char' as only yacc.c wants K&R portability.
9815 * data/glr.c (yysigned_char): Remove.
9816 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.

9820
9821 * src/main.c (main): With --trace=time, report times even if a
9822 non-fatal error occurs. Formerly, the times were reported in some
9823 such cases but not in others.
9824 * src/reader.c (reader): Just return if a complaint has been issued,
9825 instead of exiting, so that 'main' can report times.

9838
9839 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
9840 decl; not needed any more.
9841 * src/main.c (main): Use return to exit, undoing yesterday's change.
9842 The last OS that we could find where this wouldn't work is
9843 SunOS 3.5, and that's too old to worry about now.
9844
9845 * data/glr.c (struct yyltype): Define members even when not
9846 doing locations. This is more consistent with yacc.c, and it
9847 works around the following bug reports:

9851 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
9852 @acronym consistently. Standardize on "Yacc" instead of "YACC",

9860
9861 Be consistent about 'bool'; the old code used an enum in one
9862 module and an int in another, and this violates the C standard.
9863 * m4/stdbool.m4: New file, from coreutils 4.5.3.
9864 * configure.ac (AC_HEADER_STDBOOL): Add.
9865 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

9888 What was that "2" for?
9889
9890 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
9891 * src/getargs.c (usage): Likewise.
9892
9893 * src/getargs.c (getargs): When there are too few operands, report
9894 the last one. When there are too many, report the first extra
9895 one. This is how diffutils does it.

9904 fatal): Assume prototypes.
9905 * src/complain.h: Assume prototypes.
9906 * src/system.h (PARAMS): Remove.
9907 Include <limits.h> unconditionally, since it's guaranteeed even
9908 for a freestanding C89 compiler.
9909 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.

10219 Let nondeterministic skeletons be usable with deterministic
10220 tables.
10221
10222 With the patch, GAWK compiled by GCC without -O2 passes its test
10223 suite using a GLR parser driven by LALR tables. It fails with -O2
10224 because `struct stat' gives two different answers on my machine:
10225 88 (definition of an auto var) and later 96 (memset on this var).
10226 Hence the stack is badly corrumpted. The headers inclusion is to
10227 blame: if I move the awk.h inclusion before GLR's system header
10228 inclusion, the two struct stat have the same size.

10800 to minimize the number of warnings from xgettext.

10803 outside the C locale.

10806 this is a GCC extension and is not portable to other compilers.

10809 Do not include <ctype.h>; no longer needed.
10810 Do not include <malloc.h>; no longer needed (and generates
10811 warnings on OpenBSD 3.0).
10812

10814 it's not portable.

10817 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
10818
10819 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
10820 exit status as failure, not just exit status 1. Sun C exits
10821 with status 2 sometimes.

13675 not visible.

13693 Don't use %option yylineno: it seems that then Flex imagines
13694 REJECT has been used, and therefore it won't reallocate its
13695 buffers (which makes no other sense to me than a bug). It results
13696 in warnings for `unused: yy_flex_realloc'.

14002 these states are automatically computed from the initial state.
14003 (generate_states): Adjust.
14004 * src/print.c: When reporting a rule number to the user, substract
14005 1, so that the axiom rule is rule 0, and the first user rule is 1.
14006 * src/reduce.c: Likewise.

14011 0: `$axiom: START-SYMBOL $'.

14013 number of the states has changed (the final state is no longer
14014 necessarily the last), catch up.

14037 * src/reader.c (eoftoken): New.
14038 (parse_token_decl): If the token being defined has value `0', it
14039 is the eoftoken.
14040 (packsymbols): No longer hack `tags' to insert `$' by hand.
14041 Be sure to preserve the value of the eoftoken.
14042 (reader): Make sure eoftoken is defined.
14043 Initialize nsyms to 0: now eoftoken is created just like the others.
14044 * src/print.c (print_grammar): Don't special case the eof token.
14045 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
14046 lie anyway, albeit pleasant.
14047 * tests/calc.at: Exercise error messages with eoftoken.
14048 Change the grammar so that empty input is invalid.

14478 but that's to be addressed elsewhere.
14479 No longer output the rule numbers, but do output the state number.

14889 Because useless nonterminals are now kept alive (instead of being

14900 given state.

15045 New macros.
15046 (union yyalloc): New type.
15047 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
15048 an arbitrary restriction on hosts where size_t is wider than int.
15049
15050 (yyparse): Don't dump core if alloca or malloc fails; instead, report
15051 a parser stack overflow. Allocate just one block of memory for all
15052 three stacks, instead of allocating three blocks; this typically is
15053 faster and reduces fragmentation.
15054
15055 Do not limit the number of items in the stack to a value that fits
15056 in 'int', as this is an arbitrary limit on hosts with 64-bit
15057 size_t and 32-bit int.

17285 The location tracking mechanism is precious for parse error
17286 messages. Nevertheless, it is enabled only when `@n' is used in
17287 the grammar, which is a different issue (you can use it in error

17321 Test also `--verbose', `--defines' and `--name-prefix'. Testing
17322 the latter demonstrates a flaw in the handling of non debugging
17323 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
17324 was used in order to simplify:
17325
17326 #if YYDEBUG
17327 if (yydebug)
17328 {

17335 if (yydebug)
17336 {
17337 ...
17338 }
17339

17392 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
17393 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
17394 difficult and introduced a lot of core dump. It turns out that
17395 Bison used an implementation of `xmalloc' based on `calloc', and
17396 at various places it does depend upon the initialization to 0. I
17397 have not tried to isolate the pertinent places, and all the former
17398 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

18487 declaration to allow a multi-character symbol as an alias.
18488 (parse_thong_decl): New function.

18499 Revised and use multiple warnxxx functions to avoid using VARARGS1.
18500 (read_declarations): Improve the error message for
18501 an invalid character. Do not abort.
18502 (read_declarations, copy_guard, copy_action): Use
18503 printable_version to avoid unprintable characters in printed output.

18529 (lex): Use literalchar.
18530 (lex): Implemented "..." tokens.
18531 (literalchar, lex, parse_percent_token): Made tokenbuffer
18532 always contain the token. This includes growing the token
18533 buffer while reading an integer.
18534 (parse_percent_token): Replaced if-else statement with percent_table.
18535 (parse_percent_token): Added % declarations as another
18536 way to specify the flags -n, -l, and -r. Also added hooks for
18537 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
18538 major changes to files.c.
18539 (lex) Retain in the incoming stream a character following
18540 an incorrect '/'.
18541 (skip_white_space, lex): Revised most error messages
18542 and changed fatal to warn to avoid aborting.
