No longer needed, since we're not using the stage stuff.

2
3 Version 1.49b.
4
5 * Makefile.am (SUBDIRS): Remove intl.
6 (DISTCLEANFILES): Remove.
7 * NEWS: Mention that GNU M4 is now required. Clarify what is
8 meant by "larger grammars". Mention the pt_BR translation.
9 * configure.in (AC_CHECK_DECLS): Add getenv, getopt.
10 (AM_GNU_GETTEXT_VERSION): New macro, replacing GETTEXT_VERSION var.
11 Bump version from 0.11.2 to 0.11.5.
12 (BISON_PREREQ_STAGE): Remove.
13 (AM_GNU_GETTEXT): Use external gettext.
14 (AC_OUTPUT): Remove intl/Makefile.
15
16 * config/depcomp, config/install-sh: Sync with Automake 1.6.3.
17
18 * data/glr.c: Include string.h, for strlen.
19 (yyreportParseError): Use size_t for yysize.
20 (yy_yypstack): No longer nested inside yypstates, as nested
21 functions are not portable. Do not assume size_t is the
22 same width as int.
23 (yypstates): Do not assume that ptrdiff_t is the same width
24 as int, and similarly for yyposn and YYINDEX.
25
26 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
27
28 * lib/Makefile.am (INCLUDES): Do not include from the intl
29 directory, which has been removed.
30 * src/Makefile.am (INCLUDES): Likewise.
31
32 * lib/Makefile.am (libbison_a_SOURCES): Add unlocked-io.h.

40 Do not assume that bitset_windex is the same width as unsigned.
41
42 * lib/abitset.c (abitset_unused_clear): Do not assume that

49
50 * lib/abitset.c (abitset_op1): Use -1, not ~0, as memset arg (for
51 portability to one's complement hosts!).
52 * lib/ebitset.c (ebitset_op1): Likewise.
53 * lib/lbitset.c (lbitset_op1): Likewise.
54
55 * lib/argmatch.c, lib/quotearg.c, quotearg.h: Sync with GNU tar.

61
62 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
63 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
64
65 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
66 PROTOTYPES to check for prototypes, and "defined __STDC__" to
67 check for void *.
68
69 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
70 size_t; the old version tried to do this but casted improperly.
71 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
72 (bitset_test): Now returns int, not unsigned long.
73
74 * lib/bitset_stats.c: Include "gettext.h".
75 (_): New macro.
76 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
77 name locals "index", as it generates unnecessary warnings on some
78 hosts that have an "index" function.

97 * m4/mbstate_t.m4: Sync with fileutils.
98 * m4/prereq.m4 (jm_PREREQ_QUOTEARG): AC_MBSTATE_T -> AC_TYPE_MBSTATE_T.
99
100 * po/LINGUAS: Add pt_BR.

102 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
103 lib/timevar.c.
104 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
105 manual recommends.
106 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
107
108 * src/complain.c (strerror_r): Remove decl; not needed.
109 (strerror): Use same pattern as ../lib/error.c.
110
111 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
112
113 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
114
115 * src/main.c (main): Cast result of bindtextdomain and textdomain
116 to void, to avoid a GCC warning when --disable-nls is in effect.
117
118 * src/scan-gram.l: Use strings rather than escapes when possible,
119 to minimize the number of warnings from xgettext.
120 (handle_action_dollar, handle_action_at): Don't use isdigit,
121 as it mishandles negative chars and it may not work as expected
122 outside the C locale.
123
124 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
125 this is a GCC extension and is not portable to other compilers.
126
127 * src/system.h (alloca): Use same pattern as ../lib/error.c.
128 Do not include <ctype.h>; no longer needed.
129 Do not include <malloc.h>; no longer needed (and generates
130 warnings on OpenBSD 3.0).
131
132 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
133 it's not portable.
134
135 * tests/regression.at: Do not use 'cc -c input.c -o input';
136 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
137
138 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
139 exit status as failure, not just exit status 1. Sun C exits
140 with status 2 sometimes.
141
142 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
143 Use it for the two large tests.
144
145 2002-08-02 Akim Demaille <akim@epita.fr>
146
147 * src/conflicts.c (conflicts_output): Don't output rules never
148 reduced here, since anyway that computation doesn't work.
149 * src/gram.h, src/gram.h (rule_filter_t, rule_useful_p)
150 (rule_useless_p, rule_never_reduced_p): New.
151 (grammar_rules_partial_print): Use a filter instead of a range.

155 * src/tables.c (action_row): Move the computation of rules never
156 reduced to...
157 (token_actions): here.
158 * src/main.c (main): Make the parser before making the report, so
159 that rules never reduced are computed.
160 Call grammar_rules_never_reduced_report.
161 * src/print.c (print_results): Report rules never reduced.
162 * tests/conflicts.at, tests/reduce.at: Adjust.
163
164 2002-08-01 Akim Demaille <akim@epita.fr>
165
166 Instead of attaching lookaheads and duplicating the rules being
167 reduced by a state, attach the lookaheads to the reductions.
168
169 * src/state.h (state_t): Remove the `lookaheads',
170 `lookaheads_rule' member.
171 (reductions_t): Add a `lookaheads' member.

187 * src/print.c, src/print_graph.c, src/tables.c: Adjust.
188
189 2002-08-01 Akim Demaille <akim@epita.fr>
190
191 * src/derives.h, src/derives.c (derives): A `rule_t***' instead of
192 `rule_number_t**'.
193 (set_derives, free_derives): Rename as...
194 (derives_compute, derives_free): this.
195 Adjust all dependencies.
196 * src/nullable.c (set_nullable, free_nullable): Rename as...
197 (nullable_compute, nullable_free): these.
198 (rule_list_t): Store rule_t *, not rule_number_t.
199 * src/state.c (state_rule_lookaheads_print): Directly compare rule
200 pointers, instead of their numbers.
201 * src/main.c (main): Call nullable_free, and derives_free earlier,
202 as they were lo longer used.
203
204 2002-08-01 Akim Demaille <akim@epita.fr>
205
206 * lib/timevar.c (get_time): Include children time.

218
219 2002-07-31 Akim Demaille <akim@epita.fr>
220

248
249 * lib/timevar.c, lib/timevar.h, lib/timevar.def: New,
250 stolen/adjusted from GCC.

254 * src/system.h: Adjust to using timevar.h.
255 * src/getargs.h, src/getargs.c: Support trace_time for
256 --trace=time.
257 * src/main.c (stage): Remove.
258 (main): Replace `stage' invocations with timevar calls.
259 * src/output.c: Insert pertinent timevar calls.
260
261 2002-07-31 Akim Demaille <akim@epita.fr>
262
263 Let --trace have arguments.
264
265 * src/getargs.h (enum trace_e): New.
266 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
267 (long_options, short_options): --trace/-T takes an optional
268 argument.
269 Change all the uses of trace_flag to reflect the new flags.
270 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.
271
272 Strengthen `stage' portability.
273
274 * m4/stage.m4 (BISON_PREREQ_STAGE): New.
275 * configure.in: Use it.
276 Don't check for malloc.h and sys/times.h.
277 * src/system.h: Include them when appropriate.
278 * src/main.c (stage): Compile only when mallinfo, struct mallinfo,
279 times and struct tms are available.
280
281 2002-07-30 Akim Demaille <akim@epita.fr>
282
283 In verbose parse error message, don't report `error' as an
284 expected token.
285 * tests/actions.at (Printers and Destructors): Adjust.
286 * tests/calc.at (Calculator $1): Adjust.
287 * data/yacc.c, data/glr.c, data/lalr1.c: When making the verbose

292
293 Normalize conflict related messages.

304 by conflicts.
305
306 * src/LR0.c (save_reductions): Don't make the final state too
307 different: save its reduction (accept) instead of having a state
308 without any action (no shift or goto, no reduce).
309 Note: the final state is now a ``regular'' state, i.e., the
310 parsers now contain `reduce 0' as default reduction.
311 Nevertheless, since they decide to `accept' when yystate =
312 final_state, they still will not reduce rule 0.

325 Report only when trace_flag.
326

328
329 * src/state.h, src/state.c (transitions_t): Holds state_t*'s, not
330 state_number_t.

337 2002-07-29 Akim Demaille <akim@epita.fr>
338
339 Use $accept and $end, as BYacc and BTYacc do, instead of $axiom and $.
340
341 * src/symtab.h, src/symtab.c (eoftoken, axiom): Rename as...
342 (endtoken, accept): these.
343 * src/reader.c (reader): Set endtoken's default tag to "$end".
344 Set undeftoken's tag to "$undefined" instead of "$undefined.".
345 * doc/bison.texinfo (Table of Symbols): Mention $accept and $end.
346 Adjust.
347
348 2002-07-29 Akim Demaille <akim@epita.fr>
349
350 * src/reduce.c (reduce_grammar): When the language is empty,
351 complain about the start symbol, not the axiom.
352 Use its location.
353 * tests/reduce.at (Empty Language): New.
354
355 2002-07-26 Akim Demaille <akim@epita.fr>
356
357 * src/reader.h, src/reader.c (gram_error): ... can't get
358 yycontrol without making too strong assumptions on the parser
359 itself.
360 * src/output.c (prepare_tokens): Use the real 0th value of
361 token_translations instead of `0'.
362 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
363 visible here.
364 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
365 for the time being: %locations ought to provide it to yyerror.
366
367 2002-07-25 Akim Demaille <akim@epita.fr>
368
369 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.
370 * doc/bison.texinfo (Decl Summary): s/$illegal/$undefined./.
371 * tests/regression.at (Web2c Actions): Adjust.
372
373 2002-07-25 Akim Demaille <akim@epita.fr>

378 * src/nullable.c, src/output.c, src/print.c, src/reader.c
379 * src/reduce.c: Allocate and free from &rules[0], not &rules[1].
380 Iterate from 0 to nrules.
381 Use rule_number_as_item_number and item_number_as_rule_number.
382 Adjust to `derive' now containing possibly 0.
383 * src/gram.h (rule_number_as_item_number, item_number_as_rule_number):
384 Handle the `- 1' part in rule numbers from/to item numbers.
385 * src/conflicts.c (log_resolution): Fix the message which reversed
386 shift and reduce.
387 * src/output.c (action_row): Initialize default_rule to -1.
388 (token_actions): Adjust.

411 replace...

1528 2002-06-10 Akim Demaille <akim@epita.fr>
1529
1530 Remove `%thong' support as it is undocumented, unused, duplicates
1531 `%token's job, and creates useless e-mail traffic with people who

1533 duplicates `%token's job.

1906 Adjust callers.
1907 (copy_at, copy_dollar): Instead of outputting the hard coded
1908 values of $$, $n and so forth, output invocation to b4_lhs_value,
1909 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
1910 Note: this patch partially drops `semantic-parser' support: it
1911 always does `rule_length - n', where semantic parsers ought to
1912 always use `-n'.

2017 2002-04-22 Akim Demaille <akim@epita.fr>
2018
2019 * src/reader.c (token_translations_init): 256 is now the default
2020 value for the error token, i.e., it will be assigned another
2021 number if the user assigned 256 to one of her tokens.

2025 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
2026 etc. instead of 10, 20, 30 (which was used to `jump' over error

2029 2002-04-22 Akim Demaille <akim@epita.fr>
2030

2064 2002-04-09 Akim Demaille <akim@epita.fr>
2065
2066 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
2067 full stderr, and strip it according to the bison options, instead
2068 of composing the error message from different bits.
2069 This makes it easier to check for several error messages.
2070 Adjust all the invocations.
2071 Add an invocation exercising the error token.
2072 Add an invocation demonstrating a stupid error message.
2073 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

2084 * src/symtab.h: here.
2085 (state_t.number): Is a token_number_t.
2086 * src/print.c, src/reader.c: Use undeftoken->number instead of
2087 hard coded 2.
2088 (Even though this 2 is not the same as above: the number of the
2089 undeftoken remains being 2, it is its user token number which
2090 might not be 2).
2091 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
2092 `user_token_number_max'.
2093 Output `undef_token_number'.
2094 * data/bison.simple, data/bison.c++: Use them.
2095 Be sure to map invalid yylex return values to
2096 `undef_token_number'. This saves us from gratuitous SEGV.

2114 * src/gram.h (item_number_t): New, the type of item numbers in
2115 RITEM. Note that it must be able to code symbol numbers as
2116 positive number, and the negation of rule numbers as negative
2117 numbers.
2118 Adjust all dependencies (pretty many).
2119 * src/reduce.c (rule): Remove this `short *' pointer: use
2120 item_number_t.
2121 * src/system.h (MINSHORT, MAXSHORT): Remove.
2122 Include `limits.h'.
2123 Adjust dependencies to using SHRT_MAX and SHRT_MIN.

2130 500.
2131 * tests/regression.at (Web2c Actions): Ajust.
2132
2133 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
2134 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
2135 passes, but produces negative #line number, once fixed, GCC is
2136 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
2137 C), it passes.
2138 * src/state.h (state_h): Code input lines on ints, not shorts.
2139
2140 2002-04-08 Akim Demaille <akim@epita.fr>

2258
2259 2002-04-07 Akim Demaille <akim@epita.fr>

2261 As a result of the previous patch, it is no longer needed
2262 to reorder ritem itself.
2263
2264 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
2265
2266 2002-04-07 Akim Demaille <akim@epita.fr>

2283 in the output if you don't need it.
2284
2285 2002-04-07 Akim Demaille <akim@epita.fr>
2286
2287 * src/LR0.c (new_state): Display `nstates' as the name of the

2289 Adjust to initialize first_state and last_state if needed.
2290 Be sure to distinguish the initial from the final state.
2291 (new_states): Create the itemset of the initial state, and use
2292 new_state.
2293 * src/closure.c (closure): Now that the initial state has its
2294 items properly set, there is no need for a special case when
2295 creating `ruleset'.
2296
2297 As a result, now the rule 0, reducing to $axiom, is visible in the
2298 outputs. Adjust the test suite.

2333 the usefulness of a rule, as useless rules are beyond `nrules + 1'.

2336 2002-04-07 Akim Demaille <akim@epita.fr>
2337

2339 lacking `+ 1' to nrules, Bison reported as useless a token if it
2340 was used solely to set the precedence of the last rule...
2341
2342 2002-04-07 Akim Demaille <akim@epita.fr>
2343
2344 * data/bison.c++, data/bison.simple: Don't output the current file
2345 name in #line, to avoid useless diffs between two identical
2346 outputs under different names.

2348 2002-04-07 Akim Demaille <akim@epita.fr>
2349
2350 * src/closure.c, src/print.c, src/reader.c, src/reduce.c:

2365 * src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
2366 * src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
2367 RHS, instead of being an index in RITEMS.

2637
2638 Remove the support for C++ namespace cleanliness; it was
2639 causing more problems than it was curing, since it didn't work

2685 * data/bison.c++: Replace some direct m4 expansions by constants. Be
2686 more consistent when naming methods and variables. Put preprocessor
2687 directives around tables only needed for debugging.
2688
2689 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2690
2691 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
2692 C++ parsers.
2693 (yy::b4_name::parse): Use print_.
2694
2695 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2696
2697 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
2698
2699 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
2700
2701 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
2702 C++ parsers.
2703 (yy::b4_name::parse): Build verbose error messages, and use error_.
2704
2705 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
2706
2707 * data/bison.c++: Fix m4 quoting in comments.
2708
2709 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
2710
2711 * data/bison.c++: Adjust the parser code. Fix some muscles that were
2712 not expanded by m4.
2713
2714 2002-02-05 Akim Demaille <akim@epita.fr>
2715
2716 * data/bison.c++: Adjust to the M4 back end.
2717 More is certainly needed.
2718
2719 2002-02-05 Akim Demaille <akim@epita.fr>
2720
2721 Give a try to M4 as a back end.
2722
2723 * lib/readpipe.c: New, from wdiff.
2724 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
2725 BISON_HAIRY.
2726 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
2727 specific values. Now it is m4 that performs the lookup.
2728 * src/parse-skel.y: Remove.
2729 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
2730 * src/output.c (actions_output, guards_output)
2731 (token_definitions_output): No longer keeps track of the output
2732 line number, hence remove the second argument.
2733 (guards_output): Check against the guard member of a rule, not the
2734 action member.
2735 Adjust callers.
2736 (output_skeleton): Don't look for the skeleton location, let m4 do
2737 that.
2738 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
2739 file will be used.
2740 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
2741 (prepare): Given that for the time being changesyntax is not
2742 usable in M4, rename the muscles using `-' to `_'.
2743 Define `defines_flag', `output_parser_name' and `output_header_name'.
2744 * src/output.h (actions_output, guards_output)
2745 (token_definitions_output): Adjust prototypes.
2746 * src/scan-skel.l: Instead of scanning the skeletons, it now
2747 processes the output of m4: `__oline__' and `#output'.
2748 * data/bison.simple: Adjust to be used by M4(sugar).
2749 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
2750 to date.
2751 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
2752 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
2753 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
2754 shamelessly stolen from CVS Autoconf.
2755
2756 2002-02-05 Akim Demaille <akim@epita.fr>
2757
2758 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
2759 * configure.in: Check for the declarations of free and malloc.
2760 * src/muscle_tab.c: Adjust.
2761
2762 2002-02-05 Akim Demaille <akim@epita.fr>
2763
2764 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
2765 which have no values.
2766
2767 2002-02-05 Akim Demaille <akim@epita.fr>
2768
2769 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
2770 * data/: here.
2771
2772 2002-01-29 Paul Eggert <eggert@twinsun.com>
2773
2774 * src/bison.simple (YYSIZE_T): Do not define merely because
2775 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
2776 On some platforms, <alloca.h> does not declare YYSTD (size_t).
2777
2778 2002-01-27 Akim Demaille <akim@epita.fr>
2779
2780 Fix `%nonassoc and eof'.
2781
2782 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
2783 which were not properly copied! Replace
2784 memcpy (res->errs, src->errs, src->nerrs);
2785 with
2786 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
2787 !!!
2788 * tests/regression.at (%nonassoc and eof): Adjust to newest
2789 Autotest: `.' is not in the PATH.
2790
2791 2002-01-27 Akim Demaille <akim@epita.fr>
2792
2793 * tests/sets.at (AT_EXTRACT_SETS): New.
2794 (Nullable): Use it.
2795 (Firsts): New.
2796
2797 2002-01-26 Akim Demaille <akim@epita.fr>
2798
2799 * tests/actions.at, tests/calc.at, tests/headers.at,
2800 * tests/torture.at: Adjust to the newest Autotest which no longer
2801 forces `.' in the PATH.
2802
2803 2002-01-25 Akim Demaille <akim@epita.fr>
2804
2805 * tests/regression.at (%nonassoc and eof): New.
2806 Suggested by Robert Anisko.
2807
2808 2002-01-24 Akim Demaille <akim@epita.fr>
2809
2810 Bison dumps core when trying to complain about broken input files.
2811 Reported by Cris van Pelt.
2812
2813 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
2814 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
2815 into...
2816 (Invalid inputs): Strengthen: exercise parse_percent_token.
2817
2818 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
2819
2820 * src/Makefile.am: Add bison.c++.
2821 * src/bison.c++: New skeleton.
2822
2823 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
2824
2825 * po/it.po: New.
2826
2827 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
2828
2829 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
2830
2831 2002-01-20 Marc Autret <marc@gnu.org>
2832
2833 * src/files.c (compute_output_file_names): Fix
2834
2835 2002-01-20 Marc Autret <marc@gnu.org>
2836
2837 * tests/output.at: New test.
2838 * src/files.c (compute_base_names): Don't map extensions when
2839 the YACC flag is set, use defaults.
2840 Reported by Evgeny Stambulchik.
2841
2842 2002-01-20 Marc Autret <marc@gnu.org>
2843
2844 * src/system.h: Need to define __attribute__ away for non-GCC
2845 compilers as well (i.e. the vendor C compiler).
2846 Suggested by Albert Chin-A-Young.
2847
2848 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
2849
2850 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
2851 canonical definition.
2852 * src/system.h: Use the canonical definition for PARAMS (avoids
2853 a conflict with the macro from lib/hash.h).
2854
2855 2002-01-11 Akim Demaille <akim@epita.fr>
2856
2857 * configure.in: Use AC_FUNC_STRNLEN.
2858 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
2859
2860 2002-01-09 Akim Demaille <akim@epita.fr>
2861
2862 * src/files.c, src/files.h (output_infix): New.
2863 (tab_extension): Remove.
2864 (compute_base_names): Compute the former, drop the latter.
2865 * src/output.c (prepare): Insert the muscles `output-infix', and
2866 `output-suffix'.
2867 * src/parse-skel.y (string, string.1): New.
2868 (section.header): Use it.
2869 (section.yacc): Remove.
2870 (prefix): Remove too.
2871 * src/scan-skel.l: Adjust.
2872 * src/bison.simple, src/bison.hairy: Adjust.
2873
2874 2002-01-09 Akim Demaille <akim@epita.fr>
2875
2876 * configure.in (WERROR_CFLAGS): Compute it.
2877 * src/Makefile.am (CFLAGS): Pass it.
2878 * tests/atlocal.in (CFLAGS): Idem.
2879 * src/files.c: Fix a few warnings.
2880 (get_extension_index): Remove, unused.
2881
2882 2002-01-08 Akim Demaille <akim@epita.fr>
2883
2884 * src/getargs.c (AS_FILE_NAME): New.
2885 (getargs): Use it to convert DOSish file names.
2886 * src/files.c (base_name): Rename as full_base_name to avoid
2887 clashes with `base_name ()'.
2888 (filename_split): New.
2889 (compute_base_names): N-th rewrite, using filename_split.
2890
2891 2002-01-08 Akim Demaille <akim@epita.fr>
2892
2893 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
2894 New, stolen from the Fileutils 4.1.
2895 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
2896 * configure.in: Check for the presence of memrchr, and of its
2897 prototype.
2898
2899 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
2900
2901 * lib/hash.h (__P): Added definition for this macro.
2902 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
2903 BUILT_SOURCES, to ensure they are generated first.
2904 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
2905 %error-verbose to allow bootstrapping with bison 1.30x.
2906
2907 2002-01-06 Akim Demaille <akim@epita.fr>
2908
2909 * src/reader.c (parse_braces): Don't fetch the next char, the
2910 convention is to fetch on entry.
2911 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
2912 'switch' without a following semicolon.
2913 * tests/regression.at (braces parsing): New.
2914
2915 2002-01-06 Akim Demaille <akim@epita.fr>
2916
2917 Bison is dead wrong in its RR conflict reports.
2918
2919 * tests/torture.at (GNU Cim Grammar): New.
2920 * src/conflicts.c (count_rr_conflicts): Fix.
2921
2922 2002-01-06 Akim Demaille <akim@epita.fr>
2923
2924 Creating package.m4 from configure.ac causes too many problems.
2925
2926 * tests/Makefile.am (package.m4): Create it by hand,
2927 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
2928
2929 2002-01-06 Akim Demaille <akim@epita.fr>
2930
2931 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
2932 skeleton.h.
2933
2934 2002-01-04 Paul Eggert <eggert@twinsun.com>
2935
2936 * doc/bison.texinfo (Debugging):
2937 Remove YYSTDERR; it's no longer defined or used.
2938 Also, s/cstdio.h/cstdio/.
2939
2940 2002-01-03 Akim Demaille <akim@epita.fr>
2941
2942 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
2943
2944 2002-01-03 Akim Demaille <akim@epita.fr>
2945
2946 * src/parse-skel.y (process_skeleton): Don't bind the parser's
2947 tracing code to --trace, wait for a better --trace option, with
2948 args.
2949
2950 2002-01-03 Akim Demaille <akim@epita.fr>
2951
2952 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
2953 The ISO C++ standard is extremely clear about it: stderr is
2954 considered a macro, not a regular symbol (see table 94 `Header
2955 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
2956 Therefore std:: does not apply to it. It still does with fprintf.
2957 Also, s/cstdio.h/cstdio/.
2958
2959 2002-01-03 Akim Demaille <akim@epita.fr>
2960
2961 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
2962 for non system headers.
2963
2964 2002-01-02 Akim Demaille <akim@epita.fr>
2965
2966 Equip the skeleton chain with location tracking, runtime trace,
2967 pure parser and scanner.
2968
2969 * src/parse-skel.y: Request a pure parser, locations, and prefix
2970 renaming.
2971 (%union): Having several members with the same type does not help
2972 type mismatches, simplify.
2973 (YYPRINT, yyprint): New.
2974 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
2975 (skel_error): this.
2976 Handle locations.
2977 * src/scan-skel.l: Adjust to these changes.
2978 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
2979 (LOCATION_PRINT, skel_control_t): New.
2980
2981 2001-12-30 Akim Demaille <akim@epita.fr>
2982
2983 * src/parse-skel.y: Get rid of the shift/reduce conflict:
2984 replace `gb' with BLANKS.
2985 * src/scan-skel.l: Adjust.
2986
2987 2001-12-30 Akim Demaille <akim@epita.fr>
2988
2989 * src/system.h: We don't need nor want bcopy.
2990 Throw away MS-DOS crap: we don't need getpid.
2991 * configure.in: We don't need strndup. It was even causing
2992 problems: because Flex includes the headers *before* us,
2993 _GNU_SOURCE is not defined by config.h, and therefore strndup was
2994 not visible.
2995 * lib/xstrndup.c: New.
2996 * src/scan-skel.l: Use it.
2997 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
2998 * src/parse-skel.y: Use %directives instead of #defines.
2999
3000 2001-12-30 Akim Demaille <akim@epita.fr>
3001
3002 * src/skeleton.h: New.
3003 * src/output.c (output_parser, output_master_parser): Remove, dead
3004 code.
3005 * src/output.h (get_lines_number, actions_output, guards_output)
3006 (token_definitions_output): Prototype them.
3007 * src/parse-skel.y: Add the license notice.
3008 Include output.h and skeleton.h.
3009 (process_skeleton): Returns void, and takes a single parameter.
3010 * src/scan-skel.l: Add the license notice.
3011 Include skeleton.h.
3012 Don't use %option yylineno: it seems that then Flex imagines
3013 REJECT has been used, and therefore it won't reallocate its
3014 buffers (which makes no other sense to me than a bug). It results
3015 in warnings for `unused: yy_flex_realloc'.
3016
3017 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
3018
3019 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3020 (MUSCLE_INSERT_PREFIX): ...to there.
3021 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
3022 (MUSCLE_INSERT_PREFIX): Move from here...
3023
3024 * src/bison.hairy: Add a section directive. Put braces around muscle
3025 names. This parser skeleton is still broken, but Bison should not
3026 choke on a bad muscle 'syntax'.
3027 * src/bison.simple: Add a section directive. Put braces around muscle
3028 names.
3029
3030 * src/files.h (strsuffix, stringappend): Add declarations.
3031 (tab_extension): Add declaration.
3032 (short_base_name): Add declaration.
3033
3034 * src/files.c (strsuffix, stringappend): No longer static. These
3035 functions are used in the skeleton parser.
3036 (tab_extension): New.
3037 (compute_base_names): Use the computations done in this function
3038 to guess if the generated parsers should have '.tab' in their
3039 names.
3040 (short_base_name): No longer static.
3041
3042 * src/output.c (output_skeleton): New.
3043 (output): Disable call to output_master_parser, and give a try to
3044 a new skeleton handling system.
3045 (guards_output, actions_output): No longer static.
3046 (token_definitions_output, get_lines_number): No longer static.
3047
3048 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
3049
3050 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
3051 parse-skel.y.
3052
3053 * src/parse-skel.y: New file.
3054 * src/scan-skel.l: New file.
3055
3056 2001-12-29 Akim Demaille <akim@epita.fr>
3057
3058 %name-prefix is broken.
3059
3060 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
3061 Adjust all dependencies.
3062 * tests/headers.at (export YYLTYPE): Strengthen this test: use
3063 %name-prefix.
3064
3065 Renaming yylval but not yylloc is not consistent. Now we do.
3066
3067 * src/bison.simple: Prefix yylloc if used.
3068 * doc/bison.texinfo (Decl Summary): Document that.
3069
3070 2001-12-29 Akim Demaille <akim@epita.fr>
3071
3072 * doc/bison.texinfo: Promote `%long-directive' over
3073 `%long_directive'.
3074 Remove all references to fixed-output-files, yacc is enough.
3075
3076 2001-12-29 Akim Demaille <akim@epita.fr>
3077
3078 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
3079 user prologue. These are defaults.
3080 * tests/actions.at (Mid-rule actions): Make sure the user can
3081 define YYDEBUG and YYERROR_VERBOSE.
3082
3083 2001-12-29 Akim Demaille <akim@epita.fr>
3084
3085 * src/output.c (header_output): Don't forget to export YYLTYPE and
3086 yylloc.
3087 * tests/headers.at (export YYLTYPE): New, make sure it does.
3088 * tests/regression.at (%union and --defines, Invalid CPP headers):
3089 Move to...
3090 * tests/headers.at: here.
3091
3092 2001-12-29 Akim Demaille <akim@epita.fr>
3093
3094 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
3095
3096 2001-12-29 Akim Demaille <akim@epita.fr>
3097
3098 * tests/actions.at (Mid-rule actions): Output on a single line
3099 instead of several.
3100
3101 2001-12-29 Akim Demaille <akim@epita.fr>
3102
3103 * doc/bison.texinfo: Formatting changes.
3104
3105 2001-12-29 Akim Demaille <akim@epita.fr>
3106
3107 Don't store the token defs in a muscle, just be ready to output it
3108 on command. Now possible via `symbols'. Fixes a memory leak.
3109
3110 * src/output.c (token_definitions_output): New.
3111 (output_parser, header_output): Use it.
3112 * src/reader.c (symbols_save): Remove.
3113
3114 2001-12-29 Akim Demaille <akim@epita.fr>
3115
3116 * src/bison.simple: Do not provide a default for YYSTYPE and
3117 YYLTYPE before the user's prologue. Otherwise it's hardly... a
3118 default.
3119
3120 2001-12-29 Akim Demaille <akim@epita.fr>
3121
3122 Mid-rule actions are simply... ignored!
3123
3124 * src/reader.c (readgram): Be sure to attach mid-rule actions to
3125 the empty-rule associated to the dummy symbol, not to the host
3126 rule.
3127 * tests/actions.at (Mid-rule actions): New.
3128
3129 2001-12-29 Akim Demaille <akim@epita.fr>
3130
3131 Memory leak.
3132
3133 * src/reader.c (reader): Free grammar.
3134
3135 2001-12-29 Akim Demaille <akim@epita.fr>
3136
3137 Memory leak.
3138
3139 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
3140 since it allocates it for each state, although only one is needed.
3141 (allocate_storage): Do it here.
3142
3143 2001-12-29 Akim Demaille <akim@epita.fr>
3144
3145 * src/options.h, src/options.c (create_long_option_table): Rename
3146 as...
3147 (long_option_table_new): this, with a clearer prototype.
3148 (percent_table): Remove, unused,
3149 * src/getargs.c (getargs): Adjust.
3150
3151 2001-12-29 Akim Demaille <akim@epita.fr>
3152
3153 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
3154 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
3155 as states.
3156
3157 2001-12-29 Akim Demaille <akim@epita.fr>
3158
3159 * src/lalr.c (build_relations): Rename `states' as `states1'.
3160 Sorry, I don't understand exactly what it is, no better name...
3161
3162 2001-12-29 Akim Demaille <akim@epita.fr>
3163
3164 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
3165 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
3166 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
3167 as rules.
3168
3169 2001-12-29 Akim Demaille <akim@epita.fr>
3170
3171 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
3172 ago.
3173
3174 2001-12-29 Akim Demaille <akim@epita.fr>
3175
3176 * src/reader.c, src/reader.h (user_toknums): Remove.
3177 Adjust all users to use symbols[i]->user_token_number.
3178
3179 2001-12-29 Akim Demaille <akim@epita.fr>
3180
3181 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
3182 Adjust all users to use symbols[i]->prec or ->assoc.
3183
3184 2001-12-29 Akim Demaille <akim@epita.fr>
3185
3186 * src/reader.c, src/reader.h (tags): Remove.
3187 Adjust all users to use symbols[i]->tag.
3188
3189 2001-12-29 Akim Demaille <akim@epita.fr>
3190
3191 * src/gram.h, src/gram.c (symbols): New, similar to state_table
3192 and rule_table.
3193 * src/reader.c (packsymbols): Fill this table.
3194 Drop sprec.
3195 * src/conflicts.c (resolve_sr_conflict): Adjust.
3196 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
3197 single table.
3198 Use symbols[i]->tag instead of tags[i].
3199
3200 2001-12-29 Akim Demaille <akim@epita.fr>
3201
3202 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
3203 In addition, put a comment in there, to replace...
3204 * tests/regression.at (%union and C comments): Remove.
3205
3206 2001-12-29 Akim Demaille <akim@epita.fr>
3207
3208 * tests/regression.at (Web2c Actions): Blindly move the actual
3209 output as expected output. The contents *seem* right to me, but I
3210 can't pretend reading perfectly parser tables... Nonetheless, all
3211 the other tests pass correctly, the table look OK, even though the
3212 presence of `$axiom' is to be noted: AFAICS it is useless (but
3213 harmless).
3214
3215 2001-12-29 Akim Demaille <akim@epita.fr>
3216
3217 * src/reader.c (readgram): Don't add the rule 0 if there were no
3218 rules read. In other words, add it _after_ having performed
3219 grammar sanity checks.
3220 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
3221
3222 2001-12-29 Akim Demaille <akim@epita.fr>
3223
3224 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
3225 visible, and some states have now a different number.
3226
3227 2001-12-29 Akim Demaille <akim@epita.fr>
3228
3229 * src/reader.c (readgram): Bind the initial rule's lineno to that
3230 of the first rule.
3231 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
3232 (Solved SR Conflicts): Adjust rule 0's line number.
3233
3234 2001-12-29 Akim Demaille <akim@epita.fr>
3235
3236 Fix the `GAWK Grammar' failure.
3237
3238 * src/LR0.c (final_state): Initialize to -1 so that we do compute
3239 the reductions of the first state which was mistakenly confused
3240 with the final state because precisely final_state was initialized
3241 to 0.
3242 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
3243 now noticed by Bison.
3244 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
3245 have a reduction on $default.
3246
3247 2001-12-29 Akim Demaille <akim@epita.fr>
3248
3249 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
3250 rule line numbers.
3251 * src/closure.c (print_closure): Likewise.
3252 * src/derives.c (print_derives): Likewise.
3253 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
3254 now.
3255
3256 2001-12-29 Akim Demaille <akim@epita.fr>
3257
3258 * src/lalr.c (lookaheads_print): New.
3259 (lalr): Call it when --trace-flag.
3260 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
3261 are dumped.
3262
3263 2001-12-29 Akim Demaille <akim@epita.fr>
3264
3265 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
3266 when walking through ritem, even via rule->rhs.
3267 * src/reduce.c (dump_grammar, useful_production, reduce_output)
3268 (useful_production, useless_nonterminals): Likewise.
3269 (reduce_grammar_tables): Likewise, plus update nritems.
3270 * src/nullable.c (set_nullable): Likewise.
3271 * src/lalr.c (build_relations): Likewise.
3272 * tests/sets.at (Nullable): Adjust.
3273 Fortunately, now, the $axiom is no longer nullable.
3274
3275 2001-12-29 Akim Demaille <akim@epita.fr>
3276
3277 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
3278 the 0-sentinel.
3279 * src/gram.c (ritem_longest_rhs): Likewise.
3280 * src/reduce.c (nonterminals_reduce): Likewise.
3281 * src/print_graph.c (print_graph): Likewise.
3282 * src/output.c (output_rule_data): Likewise.
3283 * src/nullable.c (set_nullable): Likewise.
3284
3285 2001-12-29 Akim Demaille <akim@epita.fr>
3286
3287 * src/output.c: Comment changes.
3288
3289 2001-12-27 Paul Eggert <eggert@twinsun.com>
3290
3291 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
3292 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
3293 Sparc, as they were causing more porting problems than the
3294 (minor) performance improvement was worth.
3295
3296 Also, catch up with 1.31's YYSTD.
3297
3298 2001-12-27 Akim Demaille <akim@epita.fr>
3299
3300 * src/output.c (output_gram): Rely on nritems, not the
3301 0-sentinel. See below.
3302 Use -1 as separator, not 0.
3303 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
3304 Rely on -1 as separator in yyrhs, instead of 0.
3305 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
3306 twice `Now at end of input', therefore there are two lines less to
3307 expect.
3308
3309 2001-12-27 Akim Demaille <akim@epita.fr>
3310
3311 * tests/regression.at (Unresolved SR Conflicts):
3312 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
3313 below.
3314
3315 2001-12-27 Akim Demaille <akim@epita.fr>
3316
3317 * src/LR0.c (new_state): Recognize the final state by the fact it
3318 is reached by eoftoken.
3319 (insert_start_shifting_state, insert_eof_shifting_state)
3320 (insert_accepting_state, augment_automaton): Remove, since now
3321 these states are automatically computed from the initial state.
3322 (generate_states): Adjust.
3323 * src/print.c: When reporting a rule number to the user, substract
3324 1, so that the axiom rule is rule 0, and the first user rule is 1.
3325 * src/reduce.c: Likewise.
3326 * src/print_graph.c (print_core): For the time being, just as for
3327 the report, depend upon --trace-flags to dump the full set of
3328 items.
3329 * src/reader.c (readgram): Once the grammar read, insert the rule
3330 0: `$axiom: START-SYMBOL $'.
3331 * tests/set.at: Adjust: rule 0 is now displayed, and since the
3332 number of the states has changed (the final state is no longer
3333 necessarily the last), catch up.
3334
3335 2001-12-27 Akim Demaille <akim@epita.fr>
3336
3337 Try to make the use of the eoftoken valid. Given that its value
3338 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
3339 is used instead of > 0 where appropriate, (ii), depend upon nritems
3340 instead of the 0-sentinel.
3341
3342 * src/gram.h, src/gram.c (nritems): New.
3343 Expected to be duplication of nitems, but for the time being...
3344 * src/reader.c (packgram): Assert nritems and nitems are equal.
3345 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
3346 * src/closure.c (print_closure, print_fderives): Likewise.
3347 * src/gram.c (ritem_print): Likewise.
3348 * src/print.c (print_core, print_grammar): Likewise.
3349 * src/print_graph.c: Likewise.
3350
3351 2001-12-27 Akim Demaille <akim@epita.fr>
3352
3353 * src/main.c (main): If there are complains after grammar
3354 reductions, then output the report anyway if requested, then die.
3355 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
3356 * src/reader.c (eoftoken): New.
3357 (parse_token_decl): If the token being defined has value `0', it
3358 is the eoftoken.
3359 (packsymbols): No longer hack `tags' to insert `$' by hand.
3360 Be sure to preserve the value of the eoftoken.
3361 (reader): Make sure eoftoken is defined.
3362 Initialize nsyms to 0: now eoftoken is created just like the others.
3363 * src/print.c (print_grammar): Don't special case the eof token.
3364 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
3365 lie anyway, albeit pleasant.
3366 * tests/calc.at: Exercise error messages with eoftoken.
3367 Change the grammar so that empty input is invalid.
3368 Adjust expectations.
3369 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
3370
3371 2001-12-27 Akim Demaille <akim@epita.fr>
3372
3373 * configure.in: Check the protos of strchr ans strspn.
3374 Replace strchr if needed.
3375 * src/system.h: Provide the protos of strchr, strspn and memchr if
3376 missing.
3377 * lib/strchr.c: New.
3378 * src/reader.c (symbols_save): Use strchr.
3379
3380 2001-12-27 Akim Demaille <akim@epita.fr>
3381
3382 * src/print.c, src/print_graph.c (escape): New.
3383 Use it to quote the TAGS outputs.
3384 * src/print_graph.c (print_state): Now errors are in red, and
3385 reductions in green.
3386 Prefer high to wide: output the state number on a line of its own.
3387
3388 2001-12-27 Akim Demaille <akim@epita.fr>
3389
3390 * src/state.h, src/state.c (reductions_new): New.
3391 * src/LR0.c (set_state_table): Let all the states have a
3392 `reductions', even if reduced to 0.
3393 (save_reductions): Adjust.
3394 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
3395 * src/print.c (print_reductions, print_actions): Adjust.
3396 * src/output.c (action_row): Adjust.
3397
3398 2001-12-27 Akim Demaille <akim@epita.fr>
3399
3400 * src/state.h, src/state.c (errs_new, errs_dup): New.
3401 * src/LR0.c (set_state_table): Let all the states have an errs,
3402 even if reduced to 0.
3403 * src/print.c (print_errs, print_reductions): Adjust.
3404 * src/output.c (output_actions, action_row): Adjust.

3408
3409 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
3410
3411 2001-12-27 Akim Demaille <akim@epita.fr>
3412
3413 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
3414 * src/print.c: here.
3415 (lookaheadset, shiftset): New, used as additional storage by
3416 print_reductions.
3417 (print_results): Adjust.
3418 (print_shifts, print_gotos, print_errs): New, extracted from...
3419 (print_actions): here.
3420 * src/print_graph.c (print_actions): Remove dead code.
3421
3422 2001-12-27 Akim Demaille <akim@epita.fr>
3423
3424 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
3425 `$n' and `@n'.
3426
3427 2001-12-27 Akim Demaille <akim@epita.fr>
3428
3429 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
3430 (build_relations): Adjust.
3431
3432 2001-12-27 Akim Demaille <akim@epita.fr>
3433
3434 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
3435 duplication.
3436
3437 2001-12-27 Akim Demaille <akim@epita.fr>
3438
3439 * src/reader.c (packgram): Catch nitems overflows.
3440
3441 2001-12-27 Akim Demaille <akim@epita.fr>
3442
3443 * src/files.c, src/files.h (guard_obstack): Remove.
3444 * src/output.c (output): Adjust.
3445 * src/reader.c (parse_braces): New, factoring...
3446 (copy_action, copy_guard): these two which are renamed as...
3447 (parse_action, parse_guard): these.
3448 As a voluntary consequence, using braces around guards is now
3449 mandatory.
3450
3451 2001-12-27 Akim Demaille <akim@epita.fr>
3452
3453 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
3454 * src/reader.c (symbol_list): `guard' and `guard_line' are new
3455 members.
3456 (symbol_list_new): Adjust.
3457 (copy_action): action_line is the first line, not the last.
3458 (copy_guard): Just as for actions, store the `action' only, not
3459 the switch/case/break flesh.
3460 Don't parse the user action that might follow the guard, let...
3461 (readgram): do it, i.e., now, there can be an action after a
3462 guard.
3463 In other words the guard is just explicitly optional.
3464 (packgram): Adjust.
3465 * src/output.c (guards_output): New.
3466 (output_parser): Call it when needed.
3467 (output): Also free the guard and attrs obstacks.
3468 * src/files.c, src/files.h (obstack_save): Remove.
3469 (output_files): Remove.
3470 As a result, if one needs the former `.act' file, using an
3471 appropriate skeleton which requires actions and guards is now
3472 required.
3473 * src/main.c (main): Adjust.
3474 * tests/semantic.at: New.
3475 * tests/regression.at: Use `input.y' as input file name.
3476 Avoid 8+3 problems by requiring input.c when the test needs the
3477 parser.
3478
3479 2001-12-27 Akim Demaille <akim@epita.fr>
3480
3481 * src/reader.c (symbol_list_new): Be sure to initialize all the
3482 fields.
3483
3484 2001-12-27 Akim Demaille <akim@epita.fr>
3485
3486 All the hacks using a final pseudo state are now useless.
3487
3488 * src/LR0.c (set_state_table): state_table holds exactly nstates.
3489 * src/lalr.c (nLA): New.
3490 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
3491 instead of lookaheadsp from the pseudo state (nstate + 1).
3492
3493 2001-12-27 Akim Demaille <akim@epita.fr>
3494
3495 * src/output.c (action_row, token_actions): Use a state_t instead
3496 of a integer, and nlookaheads instead of the following state's
3497 lookaheadsp.
3498
3499 2001-12-27 Akim Demaille <akim@epita.fr>
3500
3501 * src/conflicts.c (log_resolution, flush_shift)
3502 (resolve_sr_conflict, set_conflicts, solve_conflicts)
3503 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
3504 (conflicts_print, print_reductions): Use a state_t instead of an
3505 integer when referring to a state.
3506 As much as possible, depend upon nlookaheads, instead of the
3507 `lookaheadsp' member of the following state (since lookaheads of
3508 successive states are successive, the difference between state n + 1
3509 and n served as the number of lookaheads for state n).
3510 * src/lalr.c (add_lookback_edge): Likewise.
3511 * src/print.c (print_core, print_actions, print_state)
3512 (print_results): Likewise.
3513 * src/print_graph.c (print_core, print_actions, print_state)
3514 (print_graph): Likewise.
3515 * src/conflicts.h: Adjust.
3516
3517 2001-12-27 Akim Demaille <akim@epita.fr>
3518
3519 * src/bison.hairy: Formatting/comment changes.
3520 ANSIfy.
3521 Remove `register' indications.
3522 Add plenty of `static'.
3523
3524 2001-12-27 Akim Demaille <akim@epita.fr>
3525
3526 * src/output.c (prepare): Drop the muscle `ntbase' which
3527 duplicates ntokens.
3528 * src/bison.simple: Formatting/comment changes.
3529 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
3530 is an undocumented synonym.
3531
3532 2001-12-22 Akim Demaille <akim@epita.fr>
3533
3534 * src/output.c (output_table_data): Change the prototype to use
3535 `int' for array ranges: some invocations do pass an int, not a
3536 short.
3537 Reported by Wayne Green.
3538
3539 2001-12-22 Akim Demaille <akim@epita.fr>
3540
3541 Some actions of web2c.y are improperly triggered.
3542 Reported by Mike Castle.
3543
3544 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
3545 * tests/regression.at (Web2c): Rename as...
3546 (Web2c Report): this.
3547 (Web2c Actions): New.
3548
3549 2001-12-22 Akim Demaille <akim@epita.fr>
3550
3551 Reductions in web2c.y are improperly reported.
3552 Reported by Mike Castle.
3553
3554 * src/conflicts.c (print_reductions): Fix.
3555 * tests/regression.at (Web2c): New.
3556
3557 2001-12-18 Akim Demaille <akim@epita.fr>
3558
3559 Some host fail on `assert (!"foo")', which expands to
3560 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
3561 Reported by Nelson Beebee.
3562
3563 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
3564 `#define it_succeeded 0' and `assert (it_succeeded)'.
3565
3566 2001-12-17 Marc Autret <autret_m@epita.fr>
3567
3568 * src/bison.simple: Don't hard code the skeleton line and filename.
3569 * src/output.c (output_parser): Rename 'line' as 'output_line'.
3570 New line counter 'skeleton_line' (skeleton-line muscle).
3571
3572 2001-12-17 Paul Eggert <eggert@twinsun.com>
3573
3574 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
3575 YYDEBUG must be defined to a nonzero value.
3576
3577 * src/bison.simple (yytname): Do not assume that the user defines
3578 YYDEBUG to a properly parenthesized expression.
3579
3580 2001-12-17 Akim Demaille <akim@epita.fr>
3581
3582 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
3583 nlookaheads is a new member.
3584 Adjust all users.
3585 * src/lalr.h (nlookaheads): Remove this orphan declaration.
3586 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
3587 state.
3588
3589 2001-12-17 Akim Demaille <akim@epita.fr>
3590
3591 * src/files.h, src/files.c (open_files, close_files): Remove.
3592 * src/main.c (main): Don't open/close files, nor invoke lex_free,
3593 let...
3594 * src/reader.c (reader): Do it.
3595
3596 2001-12-17 Akim Demaille <akim@epita.fr>
3597
3598 * src/conflicts.c (print_reductions): Formatting changes.
3599
3600 2001-12-17 Akim Demaille <akim@epita.fr>
3601
3602 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
3603 (flush_reduce): New.
3604 (resolve_sr_conflict): Adjust.
3605
3606 2001-12-17 Akim Demaille <akim@epita.fr>
3607
3608 * src/output.c (output_obstack): Be static and rename as...
3609 (format_obstack): this, to avoid any confusion with files.c's
3610 output_obstack.
3611 * src/reader.h (muscle_obstack): Move to...
3612 * src/output.h: here, since it's defined in output.c.
3613
3614 2001-12-17 Akim Demaille <akim@epita.fr>
3615
3616 * src/output.c (action_row, save_column, default_goto)
3617 (sort_actions, matching_state, pack_vector): Better variable
3618 locality.
3619
3620 2001-12-17 Akim Demaille <akim@epita.fr>
3621
3622 * src/output.c: Various formatting changes.
3623
3624 2001-12-17 Akim Demaille <akim@epita.fr>
3625
3626 * src/files.c (output_files): Free the output_obstack.
3627 * src/main.c (main): Call print and print_graph conditionally.
3628 * src/print.c (print): Work unconditionally.
3629 * src/print_graph.c (print_graph): Work unconditionally.
3630 * src/conflicts.c (log_resolution): Output only if verbose_flag.
3631
3632 2001-12-16 Marc Autret <autret_m@epita.fr>
3633
3634 * src/output.c (actions_output): Fix. When we use %no-lines,
3635 there is one less line per action.
3636
3637 2001-12-16 Marc Autret <autret_m@epita.fr>
3638
3639 * src/bison.simple: Remove a useless #line directive.
3640 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
3641 * src/output.c (get_lines_number): New.
3642 (output_parser): Adjust, now takes care about the lines of a
3643 output muscles.
3644 Fix line numbering.
3645 (actions_output): Computes the number of lines taken by actions.
3646 (output_master_parser): Insert new skeleton which is the name of
3647 the output parser file name.
3648
3649 2001-12-15 Marc Autret <autret_m@epita.fr>
3650
3651 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
3652
3653 2001-12-15 Marc Autret <autret_m@epita.fr>
3654
3655 * src/output.c (output_gram): Keep track of the hairy one.
3656
3657 2001-12-15 Akim Demaille <akim@epita.fr>
3658
3659 Make `make distcheck' work.
3660
3661 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
3662 system.h which uses libgettext.h.
3663
3664 2001-12-15 Akim Demaille <akim@epita.fr>
3665
3666 * src/nullable.c (set_nullable): Useless rules must be skipped,
3667 otherwise, since we range over their symbols, we might look at a
3668 nonterminal which no longer ``exists'', i.e., it is not counted in
3669 `nvars', hence we overflow our arrays.
3670
3671 2001-12-15 Akim Demaille <akim@epita.fr>
3672
3673 The header can also be produced directly, without any obstack!
3674 Yahoo!
3675
3676 * src/files.c, src/files.h (defines_obstack): Remove.
3677 (compute_header_macro): Global.
3678 (defines_obstack_save): Remove.
3679 * src/reader.c (parse_union_decl): No longer output to
3680 defines_obstack: its content can be found in the `stype' muscle
3681 anyway.
3682 (output_token_translations): Merge into...
3683 (symbols_output): this.
3684 Rename as...
3685 (symbols_save): this.
3686 (reader): Adjust.
3687 * src/output.c (header_output): New.
3688 (output): Call it.
3689
3690 2001-12-15 Akim Demaille <akim@epita.fr>
3691
3692 * src/reader.c (parse_union_decl): Instead of handling two obstack
3693 simultaneously, use one to define the `stype' muscle, and use the
3694 value of the latter to fill defines_obstack.
3695 (copy_comment): Remove.
3696 (copy_comment2): Work for a single obstack.
3697 Rename as...
3698 (copy_comment): this.
3699
3700 2001-12-15 Akim Demaille <akim@epita.fr>
3701
3702 * src/lex.c, src/lex.h (xgetc): No longer static.
3703 * src/reader.c (parse_union_decl): Revamp.
3704
3705 2001-12-15 Akim Demaille <akim@epita.fr>
3706
3707 Still making progress in separating Bison into (i) input, (ii)
3708 process, (iii) output: now we can directly output the parser file
3709 without using table_obstack at all.
3710
3711 * src/files.c, src/files.h (table_obstack): Bye bye.
3712 (parser_file_name): New.
3713 * src/files.c (compute_output_file_names): Compute it.
3714 * src/output.c (actions_output, output_parser)
3715 (output_master_parser): To a file instead of an obstack.
3716
3717 2001-12-15 Akim Demaille <akim@epita.fr>
3718
3719 Attach actions to rules, instead of pre-outputting them to
3720 actions_obstack.
3721
3722 * src/gram.h (rule_t): action and action_line are new members.
3723 * src/reader.c (symbol_list): Likewise.
3724 (copy_action): Save the actions within the rule.
3725 (packgram): Save them in rule_table.
3726 * src/output.c (actions_output): New.
3727 (output_parser): Use it on `%%actions'.
3728 (output_rule_data): Don't free rule_table.
3729 (output): Do it.
3730 (prepare): Don't save the `action' muscle.
3731 * src/bison.simple: s/%%action/%%actions/.
3732
3733 2001-12-15 Akim Demaille <akim@epita.fr>
3734
3735 * src/reader.c (copy_action): When --yacc, don't append a `;'
3736 to the user action: let it fail if lacking.
3737 Suggested by Arnold Robbins and Tom Tromey.
3738
3739 2001-12-14 Akim Demaille <akim@epita.fr>
3740
3741 * src/lex.c (literalchar): Simply return the char you decoded, non
3742 longer mess around with obstacks and int pointers.
3743 Adjust all callers.
3744
3745 2001-12-14 Akim Demaille <akim@epita.fr>
3746
3747 * src/lex.c (literalchar): Don't escape the special characters,
3748 just decode them, and keep them as char (before, eol was output as
3749 the 2 char string `\n' etc.).
3750 * src/output.c (output_rule_data): Use quotearg to output the
3751 token strings.
3752
3753 2001-12-13 Paul Eggert <eggert@twinsun.com>
3754
3755 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
3756 Do not infringe on the global user namespace when using C++.
3757 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
3758 All uses of `fprintf' and `stderr' changed.
3759
3760 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
3761
3762 2001-12-13 Akim Demaille <akim@epita.fr>
3763
3764 The computation of nullable is broken: it doesn't handle empty
3765 RHS's properly.
3766
3767 * tests/torture.at (GNU AWK Grammar): New.
3768 * tests/sets.at (Nullable): New.
3769 * src/nullable.c (set_nullable): Instead of blindly looping over
3770 `ritems', loop over the rules, and then over their rhs's.
3771
3772 Work around Autotest bugs.
3773
3774 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
3775 frame, because Autotest understand lines starting with a `+' as
3776 traces from the shell. Then, they are not processed properly.
3777 Admittedly an Autotest bug, but we don't have time to wait for
3778 Autotest to catch up.
3779 * tests/regression.at (Broken Closure): Adjust to the new table
3780 frames.
3781 Move to...
3782 * tests/sets.at: here.
3783
3784 2001-12-13 Akim Demaille <akim@epita.fr>
3785
3786 * src/closure.c (closure): Use nrules instead of playing tricks
3787 with BITS_PER_WORD.
3788
3789 2001-12-13 Akim Demaille <akim@epita.fr>
3790
3791 * src/print.c (print_actions): Output the handling of `$' as the
3792 traces do: shifting the token EOF. Before EOF was treated as a
3793 nonterminal.
3794 * tests/regression.at: Adjust some tests.
3795 * src/print_graph.c (print_core): Complete the set of items via
3796 closure. The next-to-final and final states are still unsatisfying,
3797 but that's to be addressed elsewhere.
3798 No longer output the rule numbers, but do output the state number.
3799 A single loop for the shifts + gotos is enough, but picked a
3800 distinct color for each.
3801 (print_graph): Initialize and finalize closure.
3802
3803 2001-12-13 Akim Demaille <akim@epita.fr>
3804
3805 * src/reader.c (readgram): Remove dead code, an strip useless
3806 braces.
3807 (get_type): Remove, unused.
3808
3809 2001-12-12 Akim Demaille <akim@epita.fr>
3810
3811 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
3812 on that of lib/error.c.
3813
3814 2001-12-12 Akim Demaille <akim@epita.fr>
3815
3816 Some hosts don't like `/' in includes.
3817
3818 * src/system.h: Include libgettext.h without qualifying the path.
3819 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
3820 $(top_srcdir).
3821
3822 2001-12-11 Marc Autret <autret_m@epita.fr>
3823
3824 * src/output.c (output_parser): Remove useless muscle.
3825
3826 2001-12-11 Marc Autret <autret_m@epita.fr>
3827
3828 * src/bison.simple: Remove #line just before %%epilogue. It
3829 is now handled in ...
3830 * src/reader.c (read_additionnal_code): Add the output of a
3831 #line for the epilogue.
3832
3833 2001-12-10 Marc Autret <autret_m@epita.fr>
3834
3835 * src/reader.c (copy_definition): Re-use CPP-outed code which
3836 replace precedent remove.
3837 * src/bison.simple: Remove #line before %%prologue because
3838 %%input-line is wrong at this time.
3839
3840 2001-12-10 Marc Autret <autret_m@epita.fr>
3841
3842 * src/reader.c (symbols_output): Clean up.
3843 * src/output.c (output_gram, output): Clean up.
3844
3845 2001-12-10 Akim Demaille <akim@epita.fr>
3846
3847 * src/lalr.c (initialize_lookaheads): New. Extracted from...
3848 * src/LR0.c (set_state_table): here.
3849 * src/lalr.c (lalr): Call it.
3850
3851 2001-12-10 Akim Demaille <akim@epita.fr>
3852
3853 * src/state.h (shifts): Remove the `number' member: shifts are
3854 attached to state, hence no longer need to be labelled with a
3855 state number.
3856
3857 2001-12-10 Akim Demaille <akim@epita.fr>
3858
3859 Now that states have a complete set of members, the linked list of
3860 shifts is useless: just fill directly the state's shifts member.
3861
3862 * src/state.h (shifts): Remove the `next' member.
3863 * src/LR0.c (first_state, last_state): Remove.
3864 Adjust the callers.
3865 (augment_automaton): Don't look for the shifts that must be added
3866 a shift on EOF: it is those of the state we looked for! But now,
3867 since shifts are attached, it is no longer needed to looking
3868 merely by its id: its number.
3869
3870 2001-12-10 Akim Demaille <akim@epita.fr>
3871
3872 * src/LR0.c (augment_automaton): Better variable locality.
3873 Remove an impossible branch: if there is a state corresponding to
3874 the start symbol being shifted, then there is shift for the start
3875 symbol from the initial state.
3876
3877 2001-12-10 Akim Demaille <akim@epita.fr>
3878
3879 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
3880 only when appropriate: when insert_start_shifting_state' is not
3881 invoked.
3882 * tests/regression.at (Rule Line Numbers): Adjust.
3883
3884 2001-12-10 Akim Demaille <akim@epita.fr>
3885
3886 * src/LR0.c (augment_automaton): Now that all states have shifts,
3887 merge the two cases addition shifts to the initial state.
3888
3889 2001-12-10 Akim Demaille <akim@epita.fr>
3890
3891 * src/lalr.c (set_state_table): Move to...
3892 * src/LR0.c: here.
3893 * src/lalr.c (lalr): Don't call it...
3894 * src/LR0.c (generate_states): do it.
3895 * src/LR0.h (first_state): Remove, only the table is used.
3896
3897 2001-12-10 Akim Demaille <akim@epita.fr>
3898
3899 * src/LR0.h (first_shift, first_reduction): Remove.
3900 * src/lalr.c: Don't use first_shift: find shifts through the
3901 states.
3902
3903 2001-12-10 Akim Demaille <akim@epita.fr>
3904
3905 * src/LR0.c: Attach shifts to states as soon as they are
3906 computed.
3907 * src/lalr.c (set_state_table): Instead of assigning shifts to
3908 state, just assert that the mapping was properly done.
3909
3910 2001-12-10 Akim Demaille <akim@epita.fr>
3911
3912 * src/LR0.c (insert_start_shift): Rename as...
3913 (insert_start_shifting_state): this.
3914 (insert_eof_shifting_state, insert_accepting_state): New.
3915 (augment_automaton): Adjust.
3916 Better locality of the variables.
3917 When looking if the start_symbol is shifted from the initial
3918 state, using `while (... symbol != start_symbol ...)' sounds
3919 better than `while (... symbol < start_symbol ...)': If fail
3920 to see how the order between symbols could be relevant!
3921
3922 2001-12-10 Akim Demaille <akim@epita.fr>
3923
3924 * src/getargs.h: Don't declare `spec_name_prefix' and
3925 `spec_file_prefix', declared by src/files.h.
3926 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
3927 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
3928 * src/output.c (prepare): Adjust.
3929 * src/reader.c (symbols_output): Likewise.
3930 * src/vmsgetargs.c: Vaguely adjust, but who cares?
3931
3932 2001-12-10 Akim Demaille <akim@epita.fr>
3933
3934 * src/muscle_tab.c (muscle_init): NULL is a better default than
3935 `"0"'.
3936
3937 2001-12-10 Akim Demaille <akim@epita.fr>
3938
3939 * src/reader.c (reader): Calling symbols_output once is enough.
3940
3941 2001-12-10 Akim Demaille <akim@epita.fr>
3942
3943 Now that states have a complete set of members, the linked list of
3944 reductions is useless: just fill directly the state's reductions
3945 member.
3946
3947 * src/state.h (struct reductions): Remove member `number' and
3948 `next'.
3949 * src/LR0.c (first_reduction, last_reduction): Remove.
3950 (save_reductions): Don't link the new reductions, store them in
3951 this_state.
3952 * src/lalr.c (set_state_table): No need to attach reductions to
3953 states, it's already done.
3954 * src/output.c (output_actions): No longer free the shifts, then
3955 the reductions, then the states: free all the states and their
3956 members.
3957
3958 2001-12-10 Akim Demaille <akim@epita.fr>
3959
3960 * src/options.c (OPTN, DRTV, BOTH): New.
3961 (option_table): Use them.
3962
3963 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
3964 the job of system.h.
3965 * src/options.c: Don't include stdio.h and xalloc.h for the same
3966 reasons.
3967
3968 2001-12-10 Akim Demaille <akim@epita.fr>
3969
3970 * src/output.c (output, prepare): Make sure the values of the
3971 muscles `action' and `prologue' are 0-terminated.
3972
3973 2001-12-10 Akim Demaille <akim@epita.fr>
3974
3975 Clean up GCC warnings.
3976
3977 * src/reader.c (copy_action): `buf' is not used.
3978 (parse_skel_decl): Be static.
3979 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
3980 * src/options.h (create_long_option_table): Have a real prototype.
3981 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
3982 (hash_delete_at): Return const void *.
3983 Adjust casts to preserve the const.
3984
3985 2001-12-10 Akim Demaille <akim@epita.fr>
3986
3987 * configure.in: Require 2.52g.
3988 M4 is not needed, but AUTOM4TE is.
3989 * m4/m4.m4: Remove.
3990 * tests/Makefile.am: Adjust.
3991
3992 2001-12-10 Akim Demaille <akim@epita.fr>
3993
3994 One structure for states is enough, even though theoretically
3995 there are LR(0) states and LALR(1) states.
3996
3997 * src/lalr.h (state_t): Remove.
3998 (state_table): Be state_t **, not state_t *.
3999 * src/state.h (core, CORE_ALLOC): Rename as...
4000 (state_t, STATE_ALLOC): this.
4001 Add the LALR(1) members: shifts, reductions, errs.
4002 * src/LR0.c (state_table): Rename as...
4003 (state_hash): this, to avoid name clashes with the global
4004 `state_table'.
4005 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
4006 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
4007
4008 2001-12-10 Akim Demaille <akim@epita.fr>
4009
4010 Bison dumps core on bash.y.
4011 Reported by Pascal Bart.
4012
4013 * src/warshall.c (bitmatrix_print): New.
4014 (TC): Use it.
4015 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
4016 j must be the outer loop.
4017 * tests/regression.at (Broken Closure): New.
4018
4019 2001-12-05 Akim Demaille <akim@epita.fr>
4020
4021 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
4022 its argument.
4023 Reported by Peter Hámorský.
4024
4025 2001-12-05 Akim Demaille <akim@epita.fr>
4026
4027 * src/conflicts.c (err_table): Remove.
4028 (resolve_sr_conflict): Adjust.
4029 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
4030 Rename as...
4031 (state_t.reductions, state_t.shifts): this.
4032
4033 2001-12-05 Akim Demaille <akim@epita.fr>
4034
4035 * src/reduce.c (reduce_grammar_tables): No longer disable the
4036 removal of useless rules via CPP but via `if (0)', so that the
4037 compiler still check the code is valid.
4038 For instance, it should have noticed `rline' no longer exists: use
4039 the `line' member of rule_t.
4040 * src/gram.c (dummy, rline): Remove, unused.
4041
4042 2001-12-05 Akim Demaille <akim@epita.fr>
4043
4044 * src/output.c (pack_vector): Use assert, not berror.
4045 * src/main.c (berror): Remove, unused.
4046
4047 2001-12-05 Akim Demaille <akim@epita.fr>
4048
4049 New experimental feature: if --verbose --trace output all the
4050 items of a state, not only its kernel.
4051
4052 * src/print.c (print_core): If `trace_flag', then invoke closure
4053 before outputting the items of the state (print_core is no longer
4054 a correct name them).
4055 (print_results): Invoke new_closure/free_closure if needed.
4056
4057 2001-12-05 Akim Demaille <akim@epita.fr>
4058
4059 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
4060 * src/closure.c, src/closure.h (itemsetsize): Rename as...
4061 (nitemset): for consistency with the rest of the project.
4062
4063 2001-12-05 Akim Demaille <akim@epita.fr>
4064
4065 * src/closure.c (print_closure): Improve.
4066 (closure): Use it for printing input and output.
4067
4068 2001-12-05 Akim Demaille <akim@epita.fr>
4069
4070 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
4071 indexed by nonterminals.
4072
4073 2001-12-05 Akim Demaille <akim@epita.fr>
4074
4075 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
4076 what it was!).
4077 * src/warshall.h: Remove accidental duplication of the content.
4078
4079 2001-12-05 Akim Demaille <akim@epita.fr>
4080

4090
4091 2001-12-05 Akim Demaille <akim@epita.fr>
4092
4093 * src/output.c (action_row): De-obfuscate
4094 using the good o' techniques: arrays not pointers, variable
4095 locality, BITISSET, RESETBIT etc.
4096
4097 2001-12-05 Akim Demaille <akim@epita.fr>
4098
4099 Pessimize the code to simplify it: from now on, all the states
4100 have a valid SHIFTS, which NSHIFTS is possibly 0.
4101
4102 * src/LR0.c (shifts_new): Be global and move to..
4103 * src/state.c, src/state.h: here.
4104 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
4105 * src/print_graph: Adjust.
4106
4107 2001-12-05 Akim Demaille <akim@epita.fr>
4108
4109 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
4110 * src/conflicts.c: Use it.
4111 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
4112 incorrectly ``simplified''.
4113
4114 2001-12-05 Akim Demaille <akim@epita.fr>
4115
4116 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
4117 using the good o' techniques: arrays not pointers, variable

4119
4120 2001-12-05 Akim Demaille <akim@epita.fr>
4121

4126
4127 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
4128 (print_reductions): De-obfuscate using the good o' techniques:
4129 arrays not pointers, variable locality, BITISSET.
4130
4131 2001-12-05 Akim Demaille <akim@epita.fr>
4132
4133 * src/conflicts.c (print_reductions): Arrays, not pointers.
4134 Use BITISSET.
4135
4136 2001-12-05 Akim Demaille <akim@epita.fr>
4137
4138 * src/conflicts.c (print_reductions): Pessimize, but clarify.
4139
4140 2001-12-05 Akim Demaille <akim@epita.fr>

4147
4148 2001-12-05 Akim Demaille <akim@epita.fr>
4149
4150 * src/conflicts.c (print_reductions): Improve variable locality.
4151
4152 2001-12-05 Akim Demaille <akim@epita.fr>
4153
4154 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
4155 * src/lalr.c: Use them.
4156
4157 2001-12-05 Akim Demaille <akim@epita.fr>
4158
4159 * src/LR0.c (augment_automaton): Formatting changes.
4160 Better variable locality.
4161
4162 2001-12-05 Akim Demaille <akim@epita.fr>
4163
4164 * src/lalr.c (matrix_print): New.
4165 (transpose): Use it.
4166 Use arrays instead of pointers.
4167
4168 2001-12-05 Akim Demaille <akim@epita.fr>
4169
4170 * src/lalr.c (maxrhs): Move to...
4171 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
4172 * src/lalr.c (build_relations): Adjust.
4173
4174 2001-12-05 Akim Demaille <akim@epita.fr>
4175
4176 * src/lalr.c (transpose): Free the memory allocated to the
4177 argument, as it is replaced by the results by the unique caller.
4178 (build_relations): Merely invoke transpose: it handles the memory
4179 deallocation.
4180 Improve variable locality.
4181 Avoid variables used as mere abbreviations.
4182 (compute_lookaheads): Use arrays instead of pointers.
4183
4184 2001-12-05 Akim Demaille <akim@epita.fr>

4196 2001-12-05 Akim Demaille <akim@epita.fr>
4197
4198 * src/lalr.c (traverse): Use arrays instead of pointers.
4199
4200 2001-12-05 Akim Demaille <akim@epita.fr>
4201
4202 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
4203 the handling of squeue.
4204 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4205
4206 2001-12-05 Akim Demaille <akim@epita.fr>
4207
4208 Because useless nonterminals are now kept alive (instead of being
4209 `destroyed'), we now sometimes examine them, and store information
4210 related to them. Hence we need to know their number, and adjust
4211 memory allocations.
4212
4213 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
4214 static.
4215 * src/LR0.c (allocate_itemsets): The memory allocated to
4216 `symbol_count' was used for two different purpose: once to count
4217 the number of occurrences of each symbol, and later reassigned to
4218 `shift_symbol', containing the symbol that can be shifted from a
4219 given state.
4220 Deobfuscate, i.e., allocate, use and free `symbol_count' here
4221 only, and...
4222 (new_itemsets): Allocate `shift_symbol' here.
4223 (allocate_itemsets): symbol_count includes useless nonterminals.
4224 Make room for them.
4225 (free_storage): Use `free', not `XFREE', for pointers that cannot
4226 be null.
4227
4228 2001-12-05 Akim Demaille <akim@epita.fr>
4229
4230 * src/nullable.c (set_nullable): Deobfuscate the handling of
4231 ritem.
4232 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
4233
4234 2001-12-05 Akim Demaille <akim@epita.fr>
4235
4236 * src/gram.c, src/gram.h (ritem_print): New.
4237 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
4238 (This useless function was defined only to work around VMS linkers
4239 that can't handle compilation units with variables only).
4240 * src/reduce.c (dump_grammar): Use it to trace the construction of
4241 ritem.
4242
4243 2001-12-04 Paul Eggert <eggert@twinsun.com>
4244
4245 * src/bison.simple (union yyalloc): Change member names
4246 to be the same as the stack names.
4247 (yyparse): yyptr is now union yyalloc *, not char *.
4248 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
4249 and may generate better code on some machines.
4250 (yystpcpy): Use prototype if __STDC__ is defined, not just
4251 if __cplusplus is defined.
4252
4253 2001-11-30 Akim Demaille <akim@epita.fr>
4254
4255 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
4256 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
4257 Gettext doesn't compile cleanly, and dies with -Werror.
4258 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
4259 Include WARNING_CFLAGS here.
4260 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
4261 before being defined.
4262
4263 2001-11-27 Paul Eggert <eggert@twinsun.com>
4264
4265 * lib/quotearg.h (quotearg_n, quotearg_n_style):
4266 First arg is int, not unsigned.
4267 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
4268 (SIZE_MAX, UINT_MAX): New macros.
4269 (quotearg_n_options): Abort if N is negative.
4270 Avoid overflow check on hosts where size_t is 64 bits and int
4271 is 32 bits, as overflow is impossible there.
4272 Fix off-by-one typo that caused unnecessary reallocation.
4273
4274 2001-11-29 Paul Eggert <eggert@twinsun.com>
4275
4276 Name space cleanup in generated parser.
4277
4278 * doc/bison.texinfo (Bison Parser): Discuss system headers
4279 and their effect on the user name space.
4280
4281 * src/bison.simple:
4282 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
4283 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
4284 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
4285
4286 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
4287 on user names when possible.
4288
4289 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
4290 Simplify test for whather <alloca.h> exists.
4291
4292 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
4293
4294 (<stdio.h>): Include if YYDEBUG.
4295
4296 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
4297 ! defined (yyoverflow) && ! defined (yymemcpy).
4298
4299 (yymemcpy, yyparse): Rename local variables as needed so that
4300 they all begin with 'yy'.
4301
4302 (yystrlen, yystpcpy): New functions.
4303
4304 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
4305 All uses changed.
4306
4307 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
4308 instead of relying on string.h functions. Use YYSTACK_ALLOC
4309 and YYSTACK_FREE instead of malloc and free.
4310
4311 2001-11-30 Akim Demaille <akim@epita.fr>
4312
4313 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions

4320
4321 2001-11-30 Akim Demaille <akim@epita.fr>
4322
4323 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
4324 if body instead of `;' to pacify GCC's warnings.
4325
4326 2001-11-30 Akim Demaille <akim@epita.fr>
4327
4328 Instead of mapping the LHS of unused rules to -1, keep the LHS
4329 valid, but flag the rules as invalid.
4330
4331 * src/gram.h (rule_t): `useful' is a new member.
4332 * src/print.c (print_grammar): Adjust.
4333 * src/derives.c (set_derives): Likewise.
4334 * src/reader.c (packgram, reduce_output): Likewise.
4335 * src/reduce.c (reduce_grammar_tables): Likewise.
4336 * tests/reduce.at (Underivable Rules, Useless Rules): New.
4337
4338 2001-11-30 Akim Demaille <akim@epita.fr>
4339
4340 * src/reduce.c (reduce_output): Formatting changes.

4344
4345 2001-11-30 Akim Demaille <akim@epita.fr>
4346
4347 * src/reduce.c (nonterminals_reduce): Instead of throwing away
4348 useless nonterminals, move them at the end of the symbol arrays.
4349 (reduce_output): Adjust.
4350 * tests/reduce.at (Useless Nonterminals): Adjust.
4351
4352 2001-11-30 Akim Demaille <akim@epita.fr>
4353
4354 * src/reduce.c: Various comment/formatting changes.
4355 (nonterminals_reduce): New, extracted from...
4356 (reduce_grammar_tables): here.
4357 (reduce_grammar): Call nonterminals_reduce.
4358
4359 2001-11-29 Paul Eggert <eggert@twinsun.com>
4360
4361 * src/bison.simple (YYSTACK_REALLOC): Remove.
4362 (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
4363 (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
4364 New macros.
4365 (union yyalloc): New type.
4366 (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
4367 an arbitrary restriction on hosts where size_t is wider than int.
4368
4369 (yyparse): Don't dump core if alloca or malloc fails; instead, report
4370 a parser stack overflow. Allocate just one block of memory for all
4371 three stacks, instead of allocating three blocks; this typically is
4372 faster and reduces fragmentation.
4373
4374 Do not limit the number of items in the stack to a value that fits
4375 in 'int', as this is an arbitrary limit on hosts with 64-bit
4376 size_t and 32-bit int.
4377
4378 2001-11-29 Marc Autret <autret_m@epita.fr>

4420
4421 2001-11-28 Akim Demaille <akim@epita.fr>
4422
4423 * src/LR0.c (shifts_new): New.
4424 (save_shifts, insert_start_shift, augment_automaton): Use it.
4425
4426 2001-11-28 Akim Demaille <akim@epita.fr>
4427
4428 * src/closure.c (closure): `b' and `ruleno' denote the same value:
4429 keep ruleno only.
4430
4431 2001-11-28 Akim Demaille <akim@epita.fr>
4432
4433 * src/closure.c (closure): Instead of looping over word in array

4435
4436 2001-11-28 Akim Demaille <akim@epita.fr>
4437
4438 * src/closure.c (closure): No longer optimize the special case
4439 where all the bits of `ruleset[r]' are set to 0, to make the code
4440 clearer.
4441
4442 2001-11-28 Akim Demaille <akim@epita.fr>
4443
4444 * src/closure.c (closure): `r' and `c' are new variables, used to
4445 de-obfuscate accesses to RULESET and CORE.
4446
4447 2001-11-28 Akim Demaille <akim@epita.fr>
4448
4449 * src/reduce.c (reduce_print): Use ngettext.
4450 (dump_grammar): Improve the trace accuracy.
4451
4452 2001-11-28 Akim Demaille <akim@epita.fr>
4453
4454 * src/reduce.c (dump_grammar): Don't translate trace messages.
4455

4457
4458 * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
4459 * src/reduce.c (reduce_grammar_tables): Do not free useless tags,

4464
4465 * src/bison.simple (YYSTACK_REALLOC): Fix typo that caused us to

4708 (print_actions): Don't output the actions as part of the nodes,
4709 since that's the job of the edges.

4803 * tests/calc.at, tests/output.at, tests/regression.at,
4804 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

4808 use abs. path to find config.h.
4809 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

4815
4816 * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

4832 * src/lex.c (parse_percent_token): Replace equal_offset with

6211
6212 * src/lex.h: Rename all the tokens:

6234 * src/reader.c (read_declarations): Adjust.
6235 * src/files.c (open_files): Don't call `compute_base_names', don't
6236 compute `attrsfile' since they depend upon data which might be
6237 *in* the input file now.
6238 (output_files): Do it here.
6239 * src/output.c (output_headers): Document the fact that this patch
6240 introduces a guaranteed SEGV for semantic parsers.
6241 * doc/bison.texinfo: Document them.
6242 * tests/suite.at: Exercise these %options.

6267 2000-12-20 Akim Demaille <akim@epita.fr>

6299 (stringappend): Be just like strcat but allocate.

6301 Try to simplify the rather hairy computation of base_name and
6302 short_base_name.

6305

6341
6342 2000-12-19 Akim Demaille <akim@epita.fr>
6343
6344 * src/files.c (open_files): Yipee! We no longer need all the code
6345 looking for `/tmp' since we have no tmp file.
6346
6347 2000-12-19 Akim Demaille <akim@epita.fr>
6348

6377 (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
6378 prevents type checking.
6379 (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
6380 cast the value to (void *): assigning a `foo *' to a `void *'
6381 variable is valid.
6382 (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
6383 * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

6427 * lib/obstack.c (obstack_grow, obstack_grow0): Rename the second
6428 argument `data' for consistency with the prototypes.
6429 Qualify it `const'.
6430 (obstack_copy, obstack_copy0): Rename the second argument as
6431 `address' for consistency. Qualify it `const'.
6432 * lib/obstack.h (obstack_copy, obstack_copy0, obstack_grow)
6433 (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
6434 `const' their input argument (`data' or `address').

6458
6459 * src/files.c (obstack_save): New function.
6460 (done): Rename as...
6461 (output_files): this.
6462 Use `obstack_save'.
6463 * src/main.c (main): Don't use `atexit' to register `done', since
6464 it no longer has to remove tmp files, just call `output_files'
6465 when there are no errors.
6466
6467 2000-11-02 Akim Demaille <akim@epita.fr>
6468

6531 (lex): Use it.
6532 * src/reader.c (copy_dollar): Likewise.
6533
6534 2000-10-16 Akim Demaille <akim@epita.fr>
6535
6536 * src/reader.c (copy_comment2): Expect the input stream to be on
6537 the `/' which is suspected to open a comment, instead of being
6538 called after `//' or `/*' was read.
6539 (copy_comment, copy_definition, parse_union_decl, copy_action)
6540 (copy_guard): Adjust.
6541
6542 2000-10-16 Akim Demaille <akim@epita.fr>
6543
6544 * src/reader.c (parse_expect_decl): Use `skip_white_space' and

6565
6566 * doc/bison.texinfo: Various typos spotted by Neil Booth.
6567
6568 2000-10-04 Akim Demaille <akim@epita.fr>
6569
6570 When a literal string is used to define two different tokens,
6571 `bison -v' segfaults.

6573
6574 * tests/regression.m4: New file.

6579 2000-10-04 Akim Demaille <akim@epita.fr>
6580
6581 * src/reader.c (parse_expect_decl): Keep `count' within the size
6582 of `buffer'.
6583 From Neil Booth.
6584
6585 2000-10-02 Paul Eggert <eggert@twinsun.com>
6586
6587 * bison.s1 (yyparse): Assign the default value
6588 unconditionally, to avoid a GCC warning and make the parser a
6589 tad smaller.
6590
6591 2000-10-02 Akim Demaille <akim@epita.fr>
6592
6593 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
6594 options.
6595
6596 2000-10-02 Akim Demaille <akim@epita.fr>
6597
6598 * src/derives.c, src/print.c, src/reduce.c: To ease the
6599 translation, move some `\n' out of the translated strings.
6600
6601 2000-10-02 Akim Demaille <akim@epita.fr>
6602
6603 The location tracking mechanism is precious for parse error
6604 messages. Nevertheless, it is enabled only when `@n' is used in
6605 the grammar, which is a different issue (you can use it in error
6606 message, but not in the grammar per se). Therefore, there should
6607 be another means to enable it.
6608
6609 * src/getargs.c (getargs): Support `--locations'.
6610 (usage): Report it.
6611 * src/getargs.h (locationsflag): Export it.
6612 * src/lex.c (percent_table): Support `%locations'.
6613 * src/reader.c (yylsp_needed): Remove this variable, now replaced
6614 with `locationsflag'.
6615 * doc/bison.texinfo: Document `--locations' and `%locations'.
6616 Sort the options.
6617 * tests/calc.m4: Test it.
6618
6619 For regularity of the names, replace each
6620 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
6621 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
6622 In addition replace each `flag' with `_flag'.
6623
6624 2000-10-02 Akim Demaille <akim@epita.fr>
6625
6626 Also test parse error messages, including with YYERROR_VERBOSE.
6627
6628 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
6629 associative).
6630 Use it to check the computations.
6631 Use it to check `nonassoc' is honored.
6632 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
6633 `--yyerror-verbose'.
6634 (_AT_CHECK_CALC): Adjust to this option.
6635 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
6636
6637 2000-10-02 Akim Demaille <akim@epita.fr>
6638
6639 Test also `--verbose', `--defines' and `--name-prefix'. Testing
6640 the latter demonstrates a flaw in the handling of non debugging
6641 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
6642 was used in order to simplify:
6643
6644 #if YYDEBUG
6645 if (yydebug)
6646 {
6647 ...
6648 }
6649 #endif
6650
6651 into
6652
6653 if (yydebug)
6654 {
6655 ...
6656 }
6657
6658 unfortunately this leads to a CPP conflict when
6659 `--name-prefix=foo' is used since it produces `#define yydebug
6660 foodebug'.
6661
6662 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
6663 (YYDPRINTF): New macro.
6664 Spread its use.
6665 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
6666 the bison options.
6667 Also test `--verbose', `--defines' and `--name-prefix'.
6668
6669 2000-10-02 Akim Demaille <akim@epita.fr>
6670
6671 Improve the readability of the produced parsers.
6672
6673 * src/bison.s1: Formatting changes.
6674 Improve the comment related to the `$' mark.
6675 (yydefault): Don't fall through to `yyresume': `goto' there.
6676 * src/output.c (output_parser): When the `$' is met, skip the end
6677 of its line.
6678 New variable, `number_of_dollar_signs', to check there's exactly
6679 one `$' in the parser skeleton.
6680
6681 2000-10-02 Akim Demaille <akim@epita.fr>
6682
6683 * lib/xstrdup.c: New file, from the fileutils.
6684 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
6685 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
6686 instead of strlen + xmalloc + strcpy.
6687 * src/symtab.c (copys): Remove, use xstrdup instead.
6688
6689 2000-10-02 Akim Demaille <akim@epita.fr>
6690
6691 * src/gram.h (associativity): New enum type which replaces the
6692 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
6693 `right_assoc', `left_assoc' and `non_assoc'.
6694 Adjust all dependencies.
6695 * src/reader.c: Formatting changes.
6696 (LTYPESTR): Don't define it, use it as a literal in
6697 `reader_output_yylsp'.
6698 * src/symtab.h (symbol_class): New enum type which replaces the
6699 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
6700 `sunknown', `stoken and `snterm'.
6701
6702 2000-10-02 Akim Demaille <akim@epita.fr>
6703
6704 * src/getargs.c (fixed_outfiles): Rename as...
6705 (yaccflag): for consistency and accuracy.
6706 Adjust dependencies.
6707
6708 2000-10-02 Akim Demaille <akim@epita.fr>
6709
6710 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
6711 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
6712 difficult and introduced a lot of core dump. It turns out that
6713 Bison used an implementation of `xmalloc' based on `calloc', and
6714 at various places it does depend upon the initialization to 0. I
6715 have not tried to isolate the pertinent places, and all the former
6716 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
6717 someone should address this issue.
6718
6719 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
6720 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

6731
6732 2000-10-02 Akim Demaille <akim@epita.fr>
6733
6734 * src/state.h (nstates, final_state, first_state, first_shift)
6735 (first_reduction): Move their exportation from here...
6736 * src/LR0.h: to here.
6737 Adjust dependencies.
6738 * src/getargs.c (statisticsflag): New variable.
6739 Add support for `--statistics'.

6818 2000-10-02 Akim Demaille <akim@epita.fr>
6819
6820 `user_toknums' is output as a `short[]' in `output.c', while it is
6821 defined as a `int[]' in `reader.c'. For consistency with the
6822 other output tables, `user_toknums' is now defined as a table of
6823 shorts.
6824
6825 * src/reader.c (user_toknums): Be a short table instead of an int
6826 table.
6827 Adjust dependencies.

6864 inclusion.
6865 Don't define PARAMS.
6866 * src/system.h: Define PARAMS.
6867 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
6868 purpose of config.h. system.h must not try to fix wrong
6869 definitions in config.h.
6870
6871 2000-09-20 Akim Demaille <akim@epita.fr>
6872

7005 * Makefile.am (SUBDIRS): Adjust.
7006 * configure.in: Adjust.

7034
7035 On syntax errors, report the token on which we choked.

7084
7085 2000-03-17 Akim Demaille <akim@epita.fr>
7086
7087 Change the handling of @s so that they behave exactly like $s.
7088 There is now a pseudo variable @$ (readble and writable), location
7089 of the lhs of the rule (by default ranging from the location of
7090 the first symbol of the rhs, to the location of the last symbol,
7091 or, if the rhs is empty, YYLLOC).

7094 yyval.
7095 (yyparse): When providing a default semantic action, provide a

7118 * src/output.c (output_rule_data): Output the documentation of

7123 2000-03-16 Akim Demaille <akim@epita.fr>
7124
7125 * src/bison.s1 [!YYDEBUG]: Define yydebug to 0. This allows to
7126 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.
7127 One `#if YYDEBUG' remains, since it uses variables which are
7128 defined only if `YYDEBUG != 0'.
7129
7130 2000-03-16 Akim Demaille <akim@epita.fr>
7131

7162 the proper line number and file name.
7163 (DEFS): Propagate the location of bison library files and of the
7164 locale files.
7165 (INCLUDES): Added `-I ..' so that one can compile with srcdir !=
7166 builddir.
7167 * acinclude.m4: Remove, replaced by the directory m4.
7168 * m4/Makefile.am (EXTRA_DIST): New variable.
7169 * m4/gettext.m4: New file, from the fileutils.

7177 Formatting changes of various comments.

7779
7780 1995-10-16 Richard Stallman <rms@gnu.org>

7783 Add new options.
7784
7785 1995-10-15 Richard Stallman <rms@gnu.org>
7786
7787 * src/vmsgetargs.c, src/getargs.c:
7788 Added -n, -k, and -raw switches.
7789 (noparserflag, toknumflag, rawtoknumflag): New variables.
7790
7791 * src/symtab.h (SALIAS):
7792 New #define for adding aliases to %token.
7793 (struct bucket): Added `alias' field.

7796 Revise error message.
7797 (print_notices): Remove final `.' from error message.
7798
7799 * src/reader.c (reader_output_yylsp):
7800 New function.
7801 (readgram): Use `#if 0' around code that accepted %command
7802 inside grammar rules: The documentation doesn't allow it,
7803 and it will fail since the %command processors scan for the next %.
7804 (parse_token_decl): Extended the %token
7805 declaration to allow a multi-character symbol as an alias.
7806 (parse_thong_decl): New function.
7807 (read_declarations): Added %thong declarations.
7808 (read_declarations): Handle NOOP to deal with allowing
7809 % declarations as another means to specify the flags.
7810 (readgram): Allow %prec prior to semantics embedded in a rule.
7811 (skip_to_char, read_declarations, copy_definition)
7812 (parse_token_decl, parse_start_decl, parse_type_decl)
7813 (parse_assoc_decl, parse_union_decl, parse_expect_decl)
7814 (get_type_name, copy_guard, copy_action, readgram)
7815 (get_type, packsymbols): Revised most error messages.
7816 Changed `fatal' to `warnxxx' to avoid aborting for error.
7817 Revised and use multiple warnxxx functions to avoid using VARARGS1.
7818 (read_declarations): Improve the error message for
7819 an invalid character. Do not abort.
7820 (read_declarations, copy_guard, copy_action): Use
7821 printable_version to avoid unprintable characters in printed output.
7822 (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
7823 (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
7824 Allow the type of a non-terminal can be given
7825 more than once, as long as all specifications give the same type.
7826
7827 * src/output.c:
7828 (output_headers, output_trailers, output, output_gram)
7829 (output_rule_data): Implement noparserflag variable.
7830 Implement toknumflag variable.
7831 (output): Call reader_output_yylsp to output LTYPESTR.
7832
7833 * src/main.c (main):
7834 If reader sees an error, don't process the grammar.
7835 (fatals): Updated to not use VARARGS1.
7836 (printable_version, int_to_string, warn, warni, warns, warnss)
7837 (warnsss): New error reporting functions. Avoid abort for error.
7838
7839 * src/lex.h:
7840 Added THONG and NOOP for alias processing.
7841 Added SETOPT for the new code that allows setting options with %flags.
7842
7843 * src/lex.c:
7844 Include getopt.h. Add some extern decls.
7845 (safegetc): New function to deal with EOF gracefully.
7846 (literalchar); new function to deal with reading \ escapes.
7847 (lex): Use literalchar.
7848 (lex): Implemented "..." tokens.
7849 (literalchar, lex, parse_percent_token): Made tokenbuffer
7850 always contain the token. This includes growing the token
7851 buffer while reading an integer.
7852 (parse_percent_token): Replaced if-else statement with percent_table.
7853 (parse_percent_token): Added % declarations as another
7854 way to specify the flags -n, -l, and -r. Also added hooks for
7855 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
7856 major changes to files.c.
7857 (lex) Retain in the incoming stream a character following
7858 an incorrect '/'.
7859 (skip_white_space, lex): Revised most error messages
7860 and changed fatal to warn to avoid aborting.
7861 (percent_table): Added %thong declarations.
7862
7863 * src/gram.h: Comment changes.
7864
7865 * src/files.c (openfiles, open_extra_files, done):
7866 Add faction flag
7867 and actfile file. Handle noparserflag. Both for -n switch.
7868
7869 * src/conflicts.c (resolve_sr_conflict):
7870 Remove use of alloca.
