174 restrictions.

226 be invoked but lookback and much of the rest of LALR isn't
227 needed.

1318
1319 There are two issues to handle: first scanning nested angle
1320 bracket pairs to support types such as std::pair< std::string,
1321 std::list<std::string> > >.
1322
1323 Another issue is to address idiosyncracies of C++: do not glue two
1324 closing angle brackets together (otherwise it's operator>>), and
1325 avoid sticking blindly a TYPE to the opening <, as it can result
1326 in '<:' which is a digraph for '['.

1638 Finer input type for yytranslate.
1639 This patch is debatable: the tradition expects yylex to return an int
1640 which happens to correspond to token_number (which is an enum). This
1641 allows for instance to return characters (such as '*' etc.). But this
1642 goes against the stronger typing I am trying to have with the new
1643 lex interface which return a symbol_type. So in this case, feed

b06df3c2
AD
1822 make_symbol provides a means to construct a full symbol (kind,
1823 value, location) in a single shot. It is meant to be a Symbol
1824 constructor, parameterized by the symbol kind so that overloading
1825 would prevent incorrect kind/value pairs. Unfortunately
1826 parameterized constructors do not work well in C++ (unless the
1827 parameter also appears as an argument, which is not acceptable),
1828 hence the use of a function instead of a constructor.

2043 Change the handling of the symbols in the skeletons.
2044 Before we were using tables which lines were the symbols and which
2045 columns were things like number, tag, type-name etc. It is was
2046 difficult to extend: each time a column was added, all the numbers had
2047 to be updated (you asked for colon $2, not for "tag"). Also, it was
2048 hard to filter these tables when only a subset of the symbols (say the
2049 tokens, or the nterms, or the tokens that have and external number
2050 *and* a type-name) was of interest.
de62edee 2051

2052 Now instead of monolithic tables, we define one macro per cell. For
2053 instance "b4_symbol(0, tag)" is a macro name which contents is

2055 these cells.

2373 Add "%define assert" to variants.
2374 This is used to help the user catch cases where some value gets
2375 ovewritten by a new one. This should not happen, as this will
2376 probably leak.
de62edee 2377
2d32fc9f
AD
2378 Unfortunately this uncovered a bug in the C++ parser itself: the
2379 lookahead value was not destroyed between two calls to yylex. For
2380 instance if the previous lookahead was a std::string, and then an int,
2381 then the value of the std::string was correctly taken (i.e., the
2382 lookahead was now an empty string), but std::string structure itself
2383 was not reclaimed.
de62edee 2384
2d32fc9f
AD
2385 This is now done in variant::build(other&) (which is used to take the
2386 value of the lookahead): other is not only stolen from its value, it
2387 is also destroyed. This incurs a new performance penalty of a few
2388 percent, and union becomes faster again.

2669 Fuse the three stacks into a single one.
de62edee 2670
b06df3c2
AD
2671 In order to make it easy to perform benchmarks to ensure that
2672 there are no performance loss, lalr1.cc is forked into
2673 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
2674 lalr1.cc.
2675
2676 Meanwhile, to make sure that lalr1-fusion.cc is correctly
2677 exercized by the test suite, the user must install a symbolic link
2678 from lalr1.cc to it.

2680 Instead of having three stacks (state, value, location), use a
2681 stack of triples. This considerably simplifies the code (and it
2682 will be easier not to require locations as currently does the C++
2683 parser), and also gives a 10% speedup according to
2684 etc/bench (probably mainly since memory allocation is done once
2685 instead of three times).

2687 Another motivation is to make it easier to destruct properly
2688 semantic values: now that they are bound to their state (hence
2689 symbol type) it will be easier to call the appropriate destructor.

2736 Use variants to support objects as semantic values.
b06df3c2
AD
2737 This patch was inspired by work by Michiel De Wilde. But he used
2738 Boost variants which (i) requires Boost on the user side, (ii) is
2739 slow, and (iii) has useless overhead (the parser knows the type of
2740 the semantic value there is no reason to duplicate this
2741 information as Boost.Variants do).
2742
2743 This implementation reserves a buffer large enough to store the
2744 largest objects. yy::variant implements this buffer. It was
2745 implemented with Quentin Hocquet.

4443 move the check for disabled transitions to an aver since conflict
4444 resolution hasn't happened yet.
4445
4446 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
4447 labels a state as inconsistent just because it has error transitions.
4448 The original form of this check appeared in revision 1.1 of lalr.c,
4449 which was committed on 1991-12-21. Now (at least), changing the
4450 consistency label on such a state appears to have no useful effect in
4451 any of the places it is examined, which I enumerate below. The key
4452 point to understanding each item in this enumeration is that a state
4453 with an error transition is labelled consistent in the first place only
4454 if it has no rules, so the check cannot matter for states that have
4455 rules. (1) Labelling a state as inconsistent will cause set_conflicts
4456 to try to identify its conflicts, and a state must have *rules* to have
4457 conflicts. (2) Labelling a state as inconsistent will affect how
4458 action_row sets the default *rule* for the state. (3) Labelling a
4459 state as inconsistent will cause build_relations to add lookback edges
4460 to *rules* in that state.

4961 Clean up %define and %code implementation in M4 some. Most
4962 importantly, rename all related macros to be in the b4_percent_define
4963 and b4_percent_code namespaces. Also, complete support for `.' in
4964 %define variable names and %code qualifiers.
4965 * data/bison.m4 (b4_check_user_names): Check for special
4966 "SKELETON-NAMESPACE(name)" macros instead of using two nested
4967 m4_foreach loops.
4968 (b4_get_percent_define, b4_get_percent_code): Rename to...
4969 (b4_percent_define_get, b4_percent_code_get): ... these.
4970 Extend documentation with examples.
4971 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
4972 b4_percent_define_skeleton_variables and
4973 b4_percent_code_skeleton_qualifiers.
4974 Expect any value for the %define variable `foo' to be stored in the
4975 macro named `b4_percent_define(foo)'; expect any %code blocks for the
4976 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
4977 expect any unqualified %code blocks to be stored in a macro named
4978 `b4_percent_code_unqualified'.
4979 Use m4_indir so that %define variable names and %code qualifiers can
4980 contain `.', which is allowed by the grammar parser.
4981 (b4_percent_define_default): New macro to set a default value for a
4982 %define variable.
4983 (m4_wrap): Update wrapped code, and fix some underquoting.
4984 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
4985 Expect grammar uses of %define variables and %code qualifiers to be
4986 defined in b4_percent_define_user_variables and
4987 b4_percent_code_user_qualifiers.
4988 * data/c++.m4: Use b4_percent_define_default rather than
4989 m4_define_default. Fix some underquoting. Skeleton usage of %define
4990 variable define_location_comparison now implies skeleton usage of

5100 Instead of having skeletons declare all valid %define variables and

5102 and build these lists automatically. Thus Bison will now warn when a
5103 variable or qualifier is not used by the skeleton in the current
5104 invocation regardless of whether it might sometimes be used by that
5105 skeleton in other invocations. Also, move all %define value macros to
5106 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
5107 form, which is replaced by %code.
5108 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

5110 arguments to a single list argument for names used in the skeleton

5400 Encapsulate code properties and related functionality for the various
5401 destructors, printers, and actions into a code_props structure and
5402 interface. This patch merely implements code_props in scan-code.h and
5403 scan-code.l. Future patches will rewrite other modules to use it.
5404 Discussed starting at
5405 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
5406 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
5407 consistently initialize const structs that have an empty location
5408 field.

5414 code_props with no code.
5415 (code_props_plain_init, code_props_symbol_action_init,
5416 code_props_rule_action_init, code_props_translate_code): The rest of
5417 the new code_props functional interface. Among other things, the init
5418 functions set the code_props kind field so that
5419 code_props_translate_code will know whether to behave like
5420 translate_symbol_action, translate_rule_action, or translate_code.
5421 These old translate functions must remain until all other modules are

5429 (last_string): New static global similar to the one in scan-gram.l.
5430 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
5431 instead of rule.
5432 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
5433 code_props since Bison may one day use this information for destructors
5434 and printers.
5435 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
5436 (handle_action_dollar): Use symbol_list_n_get and set used flag
5437 directly since symbol_list_n_used_set is removed.

5441 Rewrite as wrappers around the new code_props interface.

5671 state variables required by push mode.

5673 b4_declare_parser_state_variables.
5674 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
5675 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
5676 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
5677 (yyparse or yypush_parse): For yyparse in pull mode, replace local
5678 parser state variable declarations with
5679 b4_declare_parser_state_variables.
5680 Don't initialize parser state variables when calling yypush_parse since
5681 yypstate_new already does that.
5682 Invoke the user's initial action only upon the first yypush_parse
5683 invocation.
5684 Remove all code that copies between the local parser state variables
5685 and the yypstate.

5836 `bison ', use m4_index instead of m4_substr since chopping up a string

5838
5839 Fix a couple of bugs related to special characters in user-specified
5840 file names, and make it easier for skeletons to compute output file
5841 names with the same file name prefix as Bison-computed output file
5842 names.
5843 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
5844 b4_parser_file_name and b4_spec_defines_file instead of
5845 @output_parser_name@ and @output_header_name@, which are now redundant.
5846 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
5847 b4_parser_file_name, b4_spec_defines_file, and the new
5848 @basename(FILENAME@) instead of @output_parser_name@ and
5849 @output_header_name@, which inappropriately escaped the file names as

5858 characters are escaped properly.
5859 * src/output.c (prepare): Define muscle file_name_all_but_ext as
5860 all_but_ext.
5861 For pkgdatadir muscle, maintain previous functionality by using
5862 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
5863 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
5864 digraphs would never be expanded. Hopefully no one has M4-special
5865 characters in his Bison installation path.
5866 * src/scan-skel.l: Don't parse @output_header_name@ and
5867 @output_parser_name@ anymore since they're now redundant.
5868 In @output, use decode_at_digraphs.

6089 these strings.

6099 expecting a non-zero exit status sets --leak-check=summary and
6100 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in

6732 Whether the default %destructor/%printer applies to a particular symbol
6733 isn't a question of whether the user *declares* that symbol (in %token,
6734 for example). It's a question of whether the user by any means
6735 *defines* the symbol at all (by simply using a char token, for
6736 example). $end is defined by Bison whereas any other token with token
6737 number 0 is defined by the user. The error token is always defined by
6738 Bison regardless of whether the user declares it with %token, but we
6739 may one day let the user define error as a nonterminal instead.

7803 actually have reason to modify it. Fix this by forcing
7804 nondeterministic operation at the beginning of the parse.

9277 Use unlocked I/O for a minor performance improvement on hosts like
9278 GNU/Linux and Solaris that support unlocked I/O. The basic idea

9729 that the byte '\0xff' is not printable in the C locale; it is,
9730 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are

9898 * tests/cxx-type.at: Don't pipe output of ./types through sed to

9900 and isn't needed since ./types shouldn't be emitting trailing
9901 spaces.
9902 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,

9934 Destructor cleanups and regularization among the three skeletons.
9935 * NEWS: Document the behavior changes.
9936 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
9937 stack before failing, as the cleanup code will do it for us now.
9938 * data/lalr1.cc (yyerrlab): Likewise.
9939 * data/glr.c (yyparse): Pop everything off the stack before
9940 freeing it, so that destructors get called properly.
9941 * data/lalr1.cc (yyreturn): Likewise.
9942 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
9943 This is more consistent.
9944 * doc/bison.texinfo (Destructor Decl): Mention more reasons
9945 why destructors might be called. 1.875 -> 2.1.
9946 (Destructor Decl, Decl Summary, Table of Symbols):
9947 Some English-language cleanups for %destructor.
9948 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

9957 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
9958 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
9959 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
9960 Rename yyoverflowab to yyexhaustedlab.
9961 When memory exhaustion occurs during syntax-error reporting,
9962 report it separately rather than in a single diagnostic; this
9963 eases translation.

9971 Add i18n support to the GLR skeleton. Partially fix the C++
9972 skeleton; a C++ expert needs to finish this. Remove debugging
9973 msgids; there's little point to having them translated, since they
9974 can be understood only by someone who can read the
9975 (English-language) source code.
9976
9977 Generate runtime-po/bison-runtime.pot automatically, so that we
9978 don't have to worry about garbage getting in that file. We'll
9979 make sure after the next official release that old msgids don't
9980 get lost. See
9981 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
9982
9983 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
9984 Now auto-generated.
9985 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
9986 Fix typos in explanations of the runtime file.
9987 * bootstrap: Change gettext keyword from YYI18N to YY_.
9988 Use standard Makefile.in.in in runtime-po, since we'll arrange
9989 for backward-compatible bison-runtime.po files in a different way.
9990 * data/glr.c (YY_): New macro, from yacc.c.
9991 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
9992 Translate messages intended for users.
9993 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
9994 the wording in the other skeletons. We don't know that the memory
9995 is virtual.
9996 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
9997 Use same method that yacc.c uses.
9998 Don't translate debugging messages.
9999 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
10000 it doesn't work (yet), and requires C++ expertise to fix.
10001 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
10002 Move defn to a more logical place, to be consistent with other
10003 skeletons.
10004 Don't translate debugging messages.
10005 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
10006 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
10007 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
10008 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

10022 (yyStackOverflow): Just longjmp, but with value 2 so that caller
10023 can handle the problem.

10025 (yyparse): New local variable yyresult to record the result.

10027 struct.

10358 conftest*, for benefit of CVS commands run at the same time as
10359 "configure". Add build-aux, since "bootstrap" now creates it and
10360 its subfiles.
10361 * Makefile.cfg (move_if_change): Remove.

10382 fopen-safer.c, stdio-safer.h, unistd-safer.h.
10383 * lib/subpipe.c: Include "unistd-safer.h".
10384 (create_subpipe): Make sure all the newly-created
10385 file descriptors are > 2, so that diagnostics don't
10386 get sent down them (which might cause Bison to hang, in theory).

10805 some arbitrary limits. It uses more memory but nowadays that's

11212 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
11213 whether the reducion was empty or not. This leaves room to
11214 improve the use of YYLLOC_DEFAULT in such a case.
11215 lalr1.cc is still experimental, so changing this is acceptable.
11216 And finally, there are probably not many users who changed the
11217 handling of locations in GLR, so changing is admissible too.

11365 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
11366 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
11367 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
11368 the extra Bison directives instead of the whole series.
11369 Change the grammar so that there are recoverable errors, and
11370 unrecoverable errors. Now we can have the parser give up before
11371 consuming the whole input. As a result we now can observe that
11372 the lookahead is freed when needed.
11373 Change the parser source to parse argv[1] instead of a hard coded
11374 string.
11375 Simplify yylex, and give a value and location to EOF.
11376 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
11377 passed directives already coded in the file.
11378 Add some tests to check the location of "error".
11379 For some tests, the C++ parser is correct, and not yacc.c.
11380 For other tests, they provide different, but unsatisfying, values,
11381 so keep the C++ value so that at least one parser is "correct"
11382 according to the test suite.

11564 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
11565 a seemingly endless set of combinations of versions more recent
11566 than that. The bottom line is that the current sources require
11567 fairly recent versions of the build tools, and it'll be some work
11568 to change this.

11803 case, as stos_ is now used by destructors due to the 2004-02-09
11804 change.

11830 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
11831 so that this include file can stand alone.
11832 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
11833 does this now. Include subpipe.h first after config.h, to
11834 test whether it can stand alone.
11835
11836 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
11837 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
11838 unused declaration.
11839
11840 * tests/synclines.at (%union synch line): Put a dummy member in
11841 the union, because empty unions aren't allowed in C. Caught

12084 When reducing initial empty rules, Bison parser read an initial
12085 location that is not defined. This results in garbage, and that
12086 affects Bison's own parser. Therefore we need (i) to extend Bison

12135 (yyerrlab1): Remove, but where it used to be (now the bottom part of
12136 yyerrlab), when hitting EOF, pop the whole stack here instead of
12137 merely falling thru the default error handling mechanism.
12138 (yyerrorlab): New label, with the old contents of YYERROR,
12139 plus the following change: pop the stack of rhs corresponding
12140 to the production that invoked YYERROR. That is how Yacc
12141 behaves (required by POSIX).

26ec81e0

12383 The problem was that GLR parsers did not conform to the C standard,
12384 because actions like { $1 = $2 + $3; } expanded to expressions
12385 that invoked YYFILL in separate subexpressions, and YYFILL assigned
12386 to a local variable. The C standard says that expressions
12387 like (var = f ()) + (var = f ()) have undefined behavior.
12388 Another problem was that GCC sometimes issues warnings that
12389 yyfill and its parameters are unused.
12390
12391 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
12392 as possibly unused.
12393 (yyfill): New function.
12394 (YYFILL): Use it.
12395 (yyuserAction): Change type of yynormal to bool, so that it matches
12396 the new yyfill signature. Mark it as possibly unused.
12397
12398
12399 Follow up on a bug I reported in February, where a Bison-generated
12400 parser can loop. Provide a test case and a fix for yacc.c. I
12401 don't have a fix for lalr1.cc or for glr.c, unfortunately.
12402 The original bug report is in:

12405 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
12406 macro's size was becoming unwieldy.
12407 (yyerrlab): Do not discard an empty lookahead symbol, as this
12408 might destroy garbage.
12409 (yyerrorlab): New label, with the old contents of YYERROR,
12410 plus the following change: pop the stack of rhs corresponding
12411 to the production that invoked YYERROR. That is how Yacc
12412 behaves, and POSIX requires this behavior.
12413 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
12414 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
12415 Define 'alarm' to do nothing if unistd.h is not available.
12416 Add a new rule "exp: '-' error;" to test the above change to
12417 data/yacc.c. Use 'alarm' to abort any test taking longer than
12418 10 seconds, as it's probably looping.
12419 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
12420 Also, the new yacc.c generates two fewer diagnostics for an
12421 existing test.

13071 popped). This means that the initial elements will not be freed

13073 these elements have fake values.

13178 Version 1.75f.
13179
13180 Switch back to the Yacc style of conflict reports, undoing some
13181 of the 2002-07-30 change.
13182 * doc/bison.texinfo (Understanding): Use Yacc style for
13183 conflict reports. Also, use new way of locating rules.
13184 * src/conflicts.c (conflict_report):
13185 Renamed from conflict_report_yacc, removing the old
13186 'conflict_report'. Translate the entire conflict report at once,
13187 so that we don't assume that "," has the same interpretation in
13188 all languages.
13189 (conflicts_output): Use Yacc-style conflict report for each state,
13190 instead of our more-complicated style.
13191 (conflicts_print): Use Yacc-style conflict report, except print
13192 the input file name when not emulating Yacc.
13193 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
13194 Conflicted Reduction, %expect not enough, %expect too much,
13195 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
13196 * tests/existing.at (GNU Cim Grammar): Likewise.
13197 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
13198
13199 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
13200 fatal): Don't invoke fflush; it's not needed and it might even be
13201 harmful for stdout, as stdout might not be open.
13202 * src/reduce.c (reduce_print): Likewise.

13206 Fix a bug where error locations were not being recorded correctly.
13207 This problem was originally reported by Paul Hilfinger in
161a71f3 13208 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.

13209
13210 * data/yacc.c (yyparse): New local var yylerrsp, to record the
13211 top of the location stack's error locations.
13212 (yyerrlab): Set it. When discarding a token, push its location
13213 onto yylerrsp so that we don't lose track of the error's end.
13214 (yyerrlab1): Now is only the target of YYERROR, so that we can
13215 properly record the location of the action that failed. For GCC
13216 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
13217 GCC warning about yyerrlab1 being unused if YYERROR is unused.
13218 (yyerrlab2): New label, which yyerrlab now falls through to.
13219 Compute the error's location by applying YYLLOC_DEFAULT to
13220 the locations of all the symbols that went into the error.
13221 * doc/bison.texinfo (Location Default Action): Mention that
13222 YYLLOC_DEFAULT is also invoked for syntax errors.
13223 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
13224 Error locations include the locations of all the tokens that were
13225 discarded, not just the last token.

13229 * src/files.c: Include quote.h.
13230 (compute_output_file_names): Warn if we detect conflicting
13231 outputs to the same file. This should catch the misunderstanding
13232 exemplified by Debian Bug 165349, reported by Bruce Stephens..
13233
13234 * src/conflicts.c (conflicts_print): If the user specifies
13235 "%expect N", report an error if there are any reduce/reduce
13236 conflicts. This is what the manual says should happen.
13237 This fixes Debian bug 130890, reported by Anthony DeRobertis.
13238 * tests/conflicts.at (%expect with reduce conflicts): New test.

13245 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
13246 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
13247 * src/output.c (output_skeleton): Use full path names when
13248 specifying a file to include; don't rely on include path, as
13249 it's unreliable when the working file contains a file with
13250 that name.

13257 * data/glr.c: Comment fix.

13260 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
13261 with -g option.
13262
13263 * src/parse-gram.y (declaration): Use enum "report_states" rather
13264 than its numeric value 1.
13265
13266 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
13267 opening a new one. This fixes Debian bug 165349, reported by

13275 supports $(...), as Solaris sh doesn't.
13276
13277 * src/parse-gram.y (lloc_default): Remove test for empty
13278 nonterminals at the end, since it didn't change the result.

13282 If the user does not define YYSTYPE as a macro, Bison now declares it
13283 using typedef instead of defining it as a macro. POSIX requires this.
13284 For consistency, YYLTYPE is also declared instead of defined.
13285
13286 %union directives can now have a tag before the `{', e.g., the
13287 directive `%union foo {...}' now generates the C code
13288 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
13289 The default union tag is `YYSTYPE', for compatibility with Solaris 9
13290 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
13291 instead of `yyltype'.
13292
13293 `yystype' and `yyltype' are now obsolescent macros instead of being
13294 typedefs or tags; they are no longer documented and will be
13295 withdrawn in a future release.
13296
13297 * data/glr.c (b4_location_type): Remove.
13298 (YYSTYPE): Renamed from yystype.
13299 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
13300 (struct YYLTYPE): Renamed from struct yyltype.
13301 (YYLTYPE): Renamed from yyltype.
13302 (yyltype, yystype): New (and obsolescent) macros,
13303 for backward compatibility.
13304 * data/yacc.c: Likewise.
13305
13306 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
13307 does not specify a union tag. This is for compatibility with
13308 Solaris 9 yacc.
13309
13310 * src/parse-gram.y (add_param): 2nd arg is now char * not char
13311 const *, since it is now modified by stripping surrounding { }.
13312 (current_braced_code): Remove.
13313 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
13314 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
13315 trailing " {...}". Now of type <chars>.
13316 (grammar_declaration): Adjust to bundled tokens.
13317 (code_content): Remove; stripping is now done by add_param.
13318 (print_token_value): Print contents of bundled tokens.
13319 (token_name): New function.
13320
13321 * src/reader.h (braced_code, current_braced_code): Remove.
13322 (token_name): New decl.
13323
13324 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
13325 token_type, not braced_code code_kind. All uses changed.
13326 (SC_PRE_CODE): New state, for scanning after a keyword that
13327 has (or usually has) an immediately-following braced code.
13328 (token_type): New local var, to keep track of which token type
13329 to return when scanning braced code.

dc546b0f 13331 <INITIAL>"%parse-param", <INITIAL>"%printer",

PE
13332 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
13333 instead of returning a token type immediately.
13334 (<INITIAL>"{"): Set token type.
13335 (<SC_BRACED_CODE>"}"): Use it.
13336 (handle_action_dollar, handle_action_at): Now returns bool
13337 indicating success. Fail if ! current_rule; this prevents a core dump.
13338 (handle_symbol_code_dollar, handle_symbol_code_at):
13339 Remove; merge body into caller.
13340 (handle_dollar, handle_at): Complain in invalid contexts.

13399 Remove unportable casts and storage allocation tricks.
13400 While we're at it, remove almost all casts, since they

13402
13403 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
13404
13405 * src/derives.c (derives_compute): Do not subtract NTOKENS from
13406 the pointer DSET returned by malloc; this isn't portable.
13407 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
13408 Similarly for DERIVES.

13432 since the resulting storage is always stored into.

13435 where it's needed.

13460
13461 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
13462 var instead of casting to long, to avoid casts.
13463 (prepare_states): Use MALLOC rather than alloca, so that we don't
13464 have to worry about alloca.

13471 STATE_ALLOC): Remove.
13472 (transitions_new, errs_new, reductions_new, state_new): Use malloc
13473 rather than calloc, and use offsetof to avoid allocating slightly
13474 too much storage.
13475 (state_new): Initialize all members.
13476
13477 * src/state.c (state_hash): Use unsigned accumulator, not signed.

13497 (table_grow, table_ninf_remap): Use signed table size.
13498 (save_row): Don't bother initializing locals when not needed.

13500 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
13501

14312 mishandled funny characters in file names, and anyway it isn't
14313 needed any more.
14314 * data/yacc.c: Likewise.

14327 (prepare): Don't insert output_infix, output_prefix,

14339 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.

14341

14343 them with auto vars.
14344 Switch to new escape scheme, where @ is the escape character uniformly.
14345 Abort if a stray escape character is found. Avoid unbounded input
14346 buffer when parsing non-escaped text.
14347

14361 counted in the token inserted at end of file. Now takes
14362 location_t *, not location_t, so that the location can be
14363 adjusted. All uses changed.

14371 abort ();'. This reduces the runtime of the "Many lookaheads"
14372 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

14697 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
14698 decl; not needed any more.
14699 * src/main.c (main): Use return to exit, undoing yesterday's change.
14700 The last OS that we could find where this wouldn't work is
14701 SunOS 3.5, and that's too old to worry about now.
14702
14703 * data/glr.c (struct yyltype): Define members even when not
14704 doing locations. This is more consistent with yacc.c, and it
14705 works around the following bug reports:

14710 @acronym consistently. Standardize on "Yacc" instead of "YACC",
14711 "Algol" instead of "ALGOL". Give a bit more history about BNF.

14718
14719 Be consistent about 'bool'; the old code used an enum in one
14720 module and an int in another, and this violates the C standard.
14721 * m4/stdbool.m4: New file, from coreutils 4.5.3.
14722 * configure.ac (AC_HEADER_STDBOOL): Add.
14723 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.

14747

14762 fatal): Assume prototypes.
14763 * src/complain.h: Assume prototypes.
14764 * src/system.h (PARAMS): Remove.
14765 Include <limits.h> unconditionally, since it's guaranteeed even
14766 for a freestanding C89 compiler.
14767 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.

14831 Do not create a temporary file, as that involves security and
14832 cleanup headaches. Instead, use a pair of pipes.
14833 Derived from a suggestion by Florian Krohm.

14852 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
14853 float, as this generates a warning on Solaris 8 + GCC 3.2 with
14854 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
14855 this generates a more-accurate value anyway.
14856

15077 Let nondeterministic skeletons be usable with deterministic
15078 tables.
15079
15080 With the patch, GAWK compiled by GCC without -O2 passes its test
15081 suite using a GLR parser driven by LALR tables. It fails with -O2
15082 because `struct stat' gives two different answers on my machine:
15083 88 (definition of an auto var) and later 96 (memset on this var).
15084 Hence the stack is badly corrumpted. The headers inclusion is to
15085 blame: if I move the awk.h inclusion before GLR's system header
15086 inclusion, the two struct stat have the same size.

15560 functions are not portable. Do not assume size_t is the
15561 same width as int.

15563 as int, and similarly for yyposn and YYINDEX.
15564

15607
15608 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
15609 size_t; the old version tried to do this but casted improperly.

15614 (_): New macro.

15645 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

15655 to void, to avoid a GCC warning when --disable-nls is in effect.
15656
15657 * src/scan-gram.l: Use strings rather than escapes when possible,
15658 to minimize the number of warnings from xgettext.
15659 (handle_action_dollar, handle_action_at): Don't use isdigit,
15660 as it mishandles negative chars and it may not work as expected
15661 outside the C locale.
15662
15663 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
15664 this is a GCC extension and is not portable to other compilers.

15667 Do not include <ctype.h>; no longer needed.

15669 warnings on OpenBSD 3.0).
15670

15672 it's not portable.

15675 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
15676
15677 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
15678 exit status as failure, not just exit status 1. Sun C exits
15679 with status 2 sometimes.

18491 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
18492 The ISO C++ standard is extremely clear about it: stderr is
18493 considered a macro, not a regular symbol (see table 94 `Header
18494 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
18495 Therefore std:: does not apply to it. It still does with fprintf.
18496 Also, s/cstdio.h/cstdio/.

18505 Equip the skeleton chain with location tracking, runtime trace,
18506 pure parser and scanner.
18507
18508 * src/parse-skel.y: Request a pure parser, locations, and prefix
18509 renaming.
18510 (%union): Having several members with the same type does not help
18511 type mismatches, simplify.
18512 (YYPRINT, yyprint): New.

18529 Throw away MS-DOS crap: we don't need getpid.
18530 * configure.in: We don't need strndup. It was even causing
18531 problems: because Flex includes the headers *before* us,
18532 _GNU_SOURCE is not defined by config.h, and therefore strndup was
18533 not visible.

18549 * src/scan-skel.l: Add the license notice.
18550 Include skeleton.h.
18551 Don't use %option yylineno: it seems that then Flex imagines
18552 REJECT has been used, and therefore it won't reallocate its
18553 buffers (which makes no other sense to me than a bug). It results
18554 in warnings for `unused: yy_flex_realloc'.

19747 Because useless nonterminals are now kept alive (instead of being
19748 `destroyed'), we now sometimes examine them, and store information

19756 the number of occurrences of each symbol, and later reassigned to
19757 `shift_symbol', containing the symbol that can be shifted from a
19758 given state.
19759 Deobfuscate, i.e., allocate, use and free `symbol_count' here
19760 only, and...
19761 (new_itemsets): Allocate `shift_symbol' here.
19762 (allocate_itemsets): symbol_count includes useless nonterminals.

19765 be null.

19907
19908 (yyparse): Don't dump core if alloca or malloc fails; instead, report
19909 a parser stack overflow. Allocate just one block of memory for all
19910 three stacks, instead of allocating three blocks; this typically is
19911 faster and reduces fragmentation.

22143 The location tracking mechanism is precious for parse error
22144 messages. Nevertheless, it is enabled only when `@n' is used in
22145 the grammar, which is a different issue (you can use it in error

22179 Test also `--verbose', `--defines' and `--name-prefix'. Testing
22180 the latter demonstrates a flaw in the handling of non debugging
22181 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
22182 was used in order to simplify:
22183
22184 #if YYDEBUG
22185 if (yydebug)
22186 {
22187 ...

22193 if (yydebug)
22194 {
22195 ...
22196 }
22197
22198 unfortunately this leads to a CPP conflict when

22250 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
22251 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
22252 difficult and introduced a lot of core dump. It turns out that
22253 Bison used an implementation of `xmalloc' based on `calloc', and
22254 at various places it does depend upon the initialization to 0. I
22255 have not tried to isolate the pertinent places, and all the former
22256 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
