[bison.git] / ChangeLog
1 2009-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
2
3 Fix a --enable-gcc-warnings problem.
4 * src/scan-gram.l (SC_ESCAPED_CHARACTER): Actually use length
5 variable.
6
7 2009-07-24 Alex Rozenman <rozenmam@gmail.com>
8
9 Fix some memory leaks.
10 * src/named-ref.c: Add a pointer check (named_ref_free).
11 * src/scan-code.l: New function (variant_table_free). Called in
12 code_scanner_free.
13 * src/symlist.c: Call to named_ref_free (symbol_list_free).
14
15 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
16
17 Warn about character literals not of length one.
18 * NEWS (2.5): Document.
19 * src/scan-gram.l (INITIAL): Remove comment that we don't check
20 the length.
21 (SC_ESCAPED_CHARACTER): Warn if length is wrong.
22 * tests/input.at (Bad character literals): New test group.
23
24 2009-07-24 Joel E. Denny <jdenny@ces.clemson.edu>
25
26 * src/lalr.c (state_lookahead_tokens_count): Correct comment.
27
28 2009-07-22 Joel E. Denny <jdenny@ces.clemson.edu>
29
30 Some M4 cleanup in the testsuite.
31 Suggested by Eric Blake at
32 <http://lists.gnu.org/archive/html/bison-patches/2009-04/msg00083.html>.
33 * tests/existing.at (_AT_TEST_EXISTING_GRAMMAR): Do not
34 complicate the code by distinguishing between a missing value
35 and an empty string value for an optional argument. This fix is
36 allowed by the similar fix in AT_TEST_TABLES_AND_PARSE below.
37 * tests/local.at (_AT_TEST_TABLES_AND_PARSE): Merge into...
38 (AT_TEST_TABLES_AND_PARSE): ... this now that the special
39 arguments are not needed because of the following changes.
40 Fix stale comments.
41 Bison developers should use GNU M4 and should not use
42 POSIXLY_CORRECT when building the test suite, so do not
43 complicate the code by avoiding $10 and above.
44 Do not quote an empty string value for an optional argument, and
45 do not distinguish between a missing value and an empty string
46 value.
47
48 2009-07-21 Joel E. Denny <jdenny@ces.clemson.edu>
49
50 * m4/m4.m4: Make it a sym link to submodules/autoconf/m4/m4.m4.
51
52 2009-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
53
54 Revert unnecessary column realignment in --help output.
55 Reported by Akim Demaille at
56 <http://lists.gnu.org/archive/html/bison-patches/2009-06/msg00010.html>.
57 * src/getargs.c (usage): Here.
58
59 2009-07-04 Alex Rozenman <rozenman@gmail.com>
60
61 Alphabetical order in src/Makefile.am.
62 * src/Makefile.am: Adjust.
63
64 2009-07-04 Alex Rozenman <rozenman@gmail.com>
65
66 Style changes and factoring.
67 * src/named-ref.h: Add comments.
68 * src/parse-gram.y: Readability and style changes.
69 * src/reader.c: Factoring: assign_named_ref function.

71 parse_named_ref to parse_ref. Use "c-ctype.h" from gnulib.
72 Use "unsigned" type for variant index. Improve readablity.
73 * src/scan-gram.l: Change error messages and add comments.
74 * src/symlist.h: symbol_list_null: New function decl.
75 * src/symlist.c: symbol_list_null: Implement here.
76 * tests/named-refs.at: Adjust for new error messages.
77
78 2009-06-29 Eric Blake <ebb9@byu.net>
79
80 scan-code: avoid compiler warnings
81 * src/scan-code.l (parse_named_ref): Use correct specifiers.
82
83 2009-06-29 Akim Demaille <demaille@gostai.com>
84
85 build: avoid concurrent extraction of calc++.
86 * examples/calc++/Makefile.am (calc.stamp): New.
87 Depend on it to create the sources of calc++ so that concurrent
88 builds don't launch several "extexi" in parallel.
89 Not only this is inefficient, this also builds incorrect sources
90 with several extractions mixed together.
91
92 2009-06-27 Alex Rozenman <rozenman@gmail.com>
93
94 Implement support for named symbol references.

103 action code. New function 'parse_named_ref'.
104 * src/scan-gram.l: Support bracketed id.

116 * src/uniqstr.c (uniqstr_new): New.
117
118 2009-06-11 Akim Demaille <demaille@gostai.com>
119
120 style changes.
121 * data/xslt/xml2dot.xsl, data/xslt/xml2xhtml.xsl: Space changes.
122 * src/print-xml.c: Style changes.
123 * tests/conflicts.at: Comment changes.
124
125 2009-06-11 Akim Demaille <demaille@gostai.com>

129 * src/gram.c (grammar_rules_print_xml): Escape the precedence for
130 XML output.
131

137 hash_insert.
138
139 2009-06-10 Akim Demaille <demaille@gostai.com>
140
141 deterministic test suite.
142 Some consistency checks on symbols are performed after all the
143 symbols were read, by an iteration over the symbol table. This
144 traversal is nondeterministic, which can be a problem for test
145 cases.
146 Avoid this.
147 Addresses another form of nondeterminism reported by Joel E. Denny.
148 http://lists.gnu.org/archive/html/bison-patches/2009-05/msg00023.html
149

151 test in two.
152 Use different file names for the three tests to make the
153 maintenance easier.
154
155 2009-06-10 Akim Demaille <demaille@gostai.com>
156
157 deterministic user-token-number redeclaration errors.

165 * tests/input.at (Numbered tokens): Adjust the expected output.
166
167 2009-05-25 Akim Demaille <demaille@gostai.com>
168
169 gnulib: update.
170 * gnulib: Update to latest.
171 * lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
172 * m4/.gitignore: Regen.

174 Call xalloc_die on hash_insert failures.
175 Requested by the new __warn_unused_result__ attribute of
176 hash_insert.

192 -F/--force-define and relative %define/-D/--define priorities.
193 * NEWS (2.5): Add documentation to -D/--define entry.
194 * build-aux/cross-options.pl: Hard-code association of
195 --force-define with %define.

200 * src/getargs.c (usage): Document -F/--force-define. Realign
201 options in output.
202 (short_options, long_options, getargs): Parse -F/--force-define,
203 and update muscle_percent_define_insert invocation.

214
215 Update some comments to make sense for -D.
216 * data/bison.m4 (b4_check_user_names): In header comments, say

228
229 2009-05-19 Joel E. Denny <jdenny@ces.clemson.edu>

231 Handle a trailing `:' in a user-supplied C++ namespace better.
232 * data/c++.m4 (b4_namespace_close): Don't let it be printed
233 among the closing braces here. This fix might make the

236
237 2009-05-19 Akim Demaille <demaille@gostai.com>
238
239 remove useless variable.
240 * src/getargs.c (skeleton_arg): Remove now useless variable.

289
290 2009-04-30 Joel E. Denny <jdenny@ces.clemson.edu>
291
292 Convert underscores to dashes in some %define variable names.
293 For now, just api.push-pull and lr.keep-unreachable-states.

300 * src/files.c (tr): Move to...
301 * src/getargs.c, src/getargs.h (tr): ... here because I can't
302 think of a better place to expose it. My logic is that, for all
303 uses of tr so far, command-line arguments can be involved, and
304 getargs.h is already included.

1314 Fix dependence on computed configure variables.
1315 * doc/Makefile.am (common_dep): Depend on $(top_srcdir)/configure not

1380 Fix some .gitignore and .cvsignore problems.
1381 * bootstrap (insert_sorted_if_absent): Replace all uses with...
1382 (insert_vc_ignore): ... this new function, which prepends `/' to all
1383 .gitignore entries before passing them to insert_sorted_if_absent.
1384 * bootstrap.conf (vc_ignore): Set to '.cvsignore .gitignore' so that
1385 .cvsignore files are maintained even though Bison developers run
1386 bootstrap while using Git.
1387 * .cvsignore (*.patch *.log log patches applied): Remove, apparently
1388 unneeded by Bison.
1389 (gnulib): Add.
1390 * .gitignore (/*.patch *.log log patches applied): Remove, broken and
1391 unneeded. Reported by Eric Blake.
1392 * lib/.gitignore (/*~): Add.
1393 * po/.cvsignore, runtime-po/.cvsignore: Sync with .gitignore.
1394 * examples/calc++/.gitignore (/calc++.exe): Add. Reported by Eric
1395 Blake.
1396 * src/.gitignore (/bison.exe): Add. Reported by Eric Blake.
1397
1398 2008-07-15 Joel E. Denny <jdenny@ces.clemson.edu>
1399
1400 Improve forward-compatibility with GNU M4. Reported by Eric Blake at
1401 <http://lists.gnu.org/archive/html/bug-bison/2008-07/msg00000.html>.
1402 * bootstrap.conf (gnulib_modules): Add unsetenv.
1403 * lib/.gitignore, lib/.cvsignore (/unsetenv.c): Add.
1404 * m4/.gitignore, m4/.cvsignore (/environ.m4): Add.
1405 (/setenv.m4): Add.
1406 * src/output.c (output_skeleton): For the m4 invocation, pass -dV as
1407 the first argument because it may become position-dependent, and unset
1408 POSIXLY_CORRECT so Bison's skeletons have access to GNU M4 extensions.
1409 Add comments explaining these issues in more detail.
1410
1411 2008-07-14 Joel E. Denny <jdenny@ces.clemson.edu>

1482 2.61. Reported by Juan Manuel Guerrero at
1483 <http://lists.gnu.org/archive/html/bug-bison/2008-04/msg00011.html>.
1484 * tests/output.at ("Output file name: ("): Comment out test case for
1485 now.
1486 ("Output file name: )"): Likewise.
1487
1488 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1489
1490 * GNUmakefile: Update git-version-gen invocation so make dist
1491 succeeds.
1492
1493 2008-04-21 Joel E. Denny <jdenny@ces.clemson.edu>
1494
1495 Update to the current gnulib CVS repository, and fix trigraph handling
1496 in Bison.
1497 * bootstrap: Update gnulib CVS repository URL.
1498 (symlink_to_dir): Encapsulate the code that guarantees the destination
1499 directory exists into...
1500 (check_dst_dir): ... this new function, and...
1501 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
1502 fail when copying files into lib/uniwidth/.
1503 * src/output.c (prepare_symbols): When writing yytname muscles, where
1504 symbol names will be encoded in C-string literals, tell quotearg to
1505 escape trigraphs. This used to be the default in gnulib.
1506 * tests/regression.at (Token definitions): Because of the change in
1507 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
1508 escapes trigraphs in symbol names. Thus, yytname no longer has
1509 trigraphs unnecessarily doubly escaped. Update test case output.
1510 Extend test case to be sure Bison's own error messages will no longer
1511 have trigraphs in symbol names unnecessarily escaped once.
1512

1523 2008-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
1524
1525 * NEWS (2.3a+): Mention that -g now takes an argument.
1526 * doc/bison.texinfo (Bison Options): Reword -W entry a little for
1527 consistency. Update the -g and -x entries now that they take
1528 arguments. Use brackets to indicate optional arguments.
1529 * src/getargs.c (usage): Explain the relationship between arguments of
1530 long and short options more completely. Document --defines and -d
1531 separately since the former takes an argument but, for POSIX Yacc, the
1532 latter does not.

1546
1547 * src/getargs.c (short_options): Split and sort for readability.
1548 -g and -x take optional arguments, just like their long options.
1549 * build-aux/cross-options.pl: Use /x to make the regexp easier to
1550 understand.
1551 Fix the handling of $opt which resulted in all the argument to be
1552 considered as optional.
1553
1554 2008-02-22 Joel E. Denny <jdenny@ces.clemson.edu>

2129 * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a `&#10;'

2172 the comma that follows it.

2183 the above macros.
2184 * data/lalr1.cc (b4_namespace): Likewise.
2185 * data/location.cc (b4_namespace): Likewise.
2186 * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry
2187 inside a new table in the general %define entry. Document `%define
2188 namespace' there as well. Point the %name-prefix entry to it since it
2189 explains it more completely in the case of C++.
2190 (C++ Bison Interface): Mention `%define namespace' instead of
2191 %name-prefix.
2192 (Table of Symbols): Remove the `%define push_pull' entry. The %define
2193 entry suffices.

2208 b4_percent_define_syncline(VARIABLE).
2209 (b4_percent_define_check_values): Use b4_percent_define_get_loc.
2210 * src/muscle_tab.c (muscle_syncline_grow): New.
2211 (muscle_code_grow): Use muscle_syncline_grow.
2212 (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and
2213 define b4_percent_define_syncline(VARIABLE).
2214 (muscle_percent_define_get_loc): New.
2215 (muscle_percent_define_get_syncline): New.
2216 (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and
2217 remove some unused variables.
2218 (muscle_percent_define_default): Record defining location as line 1
2219 rather than 0 for the sake of synchronizing #line's, and define
2220 b4_percent_define_syncline(VARIABLE).
2221 (muscle_percent_define_check_values): Use
2222 muscle_percent_define_get_loc.
2223 * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype.
2224 (muscle_percent_define_get_syncline): Prototype.
2225 * tests/skeletons.at (%define Boolean variables: invalid skeleton
2226 defaults): Update output for location change.

2231
2232 Fix some error-reporting macro bugs.
2233 * data/bison.m4 (b4_cat): New.
2234 (b4_error, b4_error_at): Use b4_cat to send error directives directly
2235 to stdout so they don't become arguments to other macros. Update
2236 comments and add examples.
2237 (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
2238 add examples.
2239 (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
2240 after printing the error directive so that M4 doesn't report subsequent
2241 problems that are induced by this problem.
2242 * src/scan-skel.l: Recognize @` digraph outside of directive arguments
2243 instead of just in them. Recognize @\n in both places. Both expand to
2244 the empty string. Needed by b4_cat.
2245 * tests/skeletons.at (Complaining during macro argument expansion):
2246 New test case.
2247 (Fatal errors make M4 exit immediately): New test case.
2248

2261
2262 2007-09-29 Joel E. Denny <jdenny@ces.clemson.edu>

2273 `%define push_pull "push"' and `%define push_pull "both"'.

2276 Pull Parser Function, Parser Create Function, Parser Delete Function):
2277 Update declarations.
2278 (Decl Summary, Table of Symbols): Replace %push-parser and

2282 definitions...
2283 * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
2284 definitions...
2285 * data/push.c: ... to here and compute them from the value of the
2286 %define variable push_pull.
2287 * data/c-skel.m4: Instead of choosing the push.c skeleton for push
2288 parsing requests here...
2289 * data/yacc.c: ... hack this to switch to push.c any time
2290 b4_use_push_pull_flag or the %define variable push_pull is set. This
2291 will go away when we mv push.c yacc.c.
2292 * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
2293 push parsing is not supported since unused %define variables are
2294 reported anyway.
2295 * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
2296 * src/muscle_tab.h (muscle_percent_define_check_values): Update

2334

2336 * src/print-xml.c, src/print-xml.h (xml_puts): Make third argument
2337 `char const *' instead of `char *'.
2338 * src/state.c (state_rule_lookahead_tokens_print_xml): Remove unused
2339 local variable `sep'.
2340
2341 2007-09-21 Paul Eggert <eggert@cs.ucla.edu>
2342
2343 * src/gram.c (rule_rhs_print_xml): Now static, since it isn't used
2344 elsewhere.
2345 * src/print-xml.c: Prefer "const" after types; that's more consistent.
2346 (xml_printf): Indent just 1 space for level.
2347 (e_char, xlate_char): Remove.
2348 (xml_escape_string): Rewrite to avoid undefined behavior (used
2349 storage that was freed from the stack).
2350 (xml_escape_n): Don't bother checking for subscript error.
2351

2403
2404 * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists

2418
2419 2007-08-17 Joel E. Denny <jdenny@ces.clemson.edu>
2420
2421 In impure push mode, don't allow more than one yypstate to be allocated
2422 since multiple impure parsers would corrupt yynerrs.
2423 * data/push.c (yypstate_allocated): New static global variable
2424 initialized to 0.
2425 (yypull_parse): If yypstate_new returns 0, don't report it as memory
2426 exhaustion if yypstate_allocated is 1, but still return 2.
2427 (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is
2428 already 1. Otherwise, set it to 1.

2501
2502 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2503
2504 Get rid of broken %no-parser, -n, and --no-parser implementation and
2505 documentation.
2506 * TODO: Don't mention them.
2507 * doc/bison.1: Likewise.
2508 * doc/bison.texinfo (Decl Summary): Likewise.
2509 (Bison Options): Likewise.
2510 (Option Cross Key): Likewise.
2511 * src/getargs.c (no_parser_flag): Remove global variable.
2512 (usage): Don't print description of -n and --no-parser.
2513 (long_options): Remove --no-parser entry here.
2514 (getargs): Remove -n case in the switch here.
2515 * src/getargs.h (no_parser_flag): Remove extern.
2516 * tests/regression.at (Web2c Actions): Remove comment that mentions
2517 --no-parser.
2518
2519 2007-08-11 Joel E. Denny <jdenny@ces.clemson.edu>
2520
2521 * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Do not
2522 name user variables starting with `yy'. Just pass NULL instead of a
2523 dummy local &yylval to yypush_parse.
2524 * tests/torture.at (AT_DATA_STACK_TORTURE): Do not name user variables
2525 starting with `yy'.
2526
2527 2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>
2528
2529 * data/yacc.c (yyexhaustedlab): Define it when YYERROR_VERBOSE is
2530 true since it's then always used regardless of whether yyoverflow is
2531 defined. Reported by Christian Burger at
2532 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
2533 * THANKS: Add Christian Burger.
2534
2535 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
2536 node names: say "Decl Summary" not "Bison Declaration Summary".
2537
2538 2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
2539
2540 * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
2541 determine whether this function has already complained about an invalid
2542 value for a %define boolean variable, don't check whether Bison has
2543 ever examined the value. As written, the check was a tautology.
2544 Instead, record and check for this complaint using a separate muscle.
2545
2546 2007-07-27 Joel E. Denny <jdenny@ces.clemson.edu>
2547
2548 Fix push parsing memory leak reported by Brandon Lucia at
2549 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00032.html>.
2550 * THANKS: Add Brandon Lucia.
2551 * data/push.c (yypstate_delete): Free the stack if it was reallocated
2552 but the parse never completed and thus freed it.
2553 * tests/Makefile.am (TESTSUITE_AT): Add push.at.
2554 * tests/testsuite.at: Include push.at.
2555 * test/push.at: New.
2556 (Push Parsing: Memory Leak for Early Deletion): New test case.
2557
2558 2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
2559
2560 Improve handling of multiple S/R conflicts in the same state and of S/R
2561 conflicts involving multiple reductions.
2562 * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
2563 set for a state here or Bison will abort if it is reassigned on a
2564 later conflicted reduction in the same state.
2565 Similarly, don't finalize and assign the solved conflicts report here
2566 or it will be lost if it is reassigned on a later conflicted reduction
2567 in the same state.
2568 (set_conflicts): Instead, assign them both here after all S/R conflicts
2569 in the state have been fully examined.
2570 * src/print.c (shift_set): Rename to...
2571 (no_reduce_set): ... this.
2572 (print_reductions): Update for rename, and add %nonassoc error action
2573 tokens to no_reduce_set so that, when printing the first remaining
2574 reduction on an error action token, the reduction is enclosed in
2575 brackets.
2576 (print_results): Update for rename.
2577 * tests/conflicts.at (Solved conflicts report for multiple reductions
2578 in a state): New test case.
2579 (%nonassoc error actions for multiple reductions in a state): New test
2580 case.
2581
2582 * src/main.c (main): Don't depend on C99 features.
2583
2584 2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
2585
2586 * build-aux/.cvsignore: Add compile.
2587 * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
2588 uniwidth.
2589
2590 2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
2591
2592 * bootstrap (slurp): Create target directories that don't exist.
2593 Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
2594
2595 2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
2596
2597 * LR0.c (new_itemsets): Fix wording in comments: say item index rather
2598 than item number.
2599 * closure.c (closure): Likewise.
2600 * state.h (reductions): Comment sorting of rules.
2601 (state): Comment sorting of items.
2602
2603 2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
2604
2605 Fix C++ test cases after recent Gnulib changes. Discussed starting at
2606 <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
2607 * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
2608 definition in order to avoid Gnulib headers since we don't use config.h
2609 here.
2610 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
2611 rather than AT_DATA so that config.h is included.
2612
2613 2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
2614
2615 * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
2616 instead of fprintf. Guard these functions with #if YYDEBUG instead of
2617 #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
2618 and so that YYFPRINTF is guaranteed to be defined here.
2619
2620 2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
2621
2622 * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
2623 with...
2624 (muscle_percent_define_check_values): ... this more helpful function.
2625 Again, it's not used yet, but it will be.
2626 * src/muscle_tab.h: Likewise.
2627
2628 Improve some comments in parser table construction.
2629 * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
2630 (generate_states): Don't mention ruleset, which is internal to closure.
2631 * src/closure.c (closure): Explain sorting of core and itemset, which
2632 is required for this function to behave correctly.
2633 * src/closure.h (closure): Mention sorting.
2634
2635 2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
2636
2637 * src/lalr.c (state_lookahead_tokens_count): For code readability,
2638 move the check for disabled transitions to an aver since conflict
2639 resolution hasn't happened yet.
2640
2641 * src/lalr.c (state_lookahead_tokens_count): Remove the check that
2642 labels a state as inconsistent just because it has error transitions.
2643 The original form of this check appeared in revision 1.1 of lalr.c,
2644 which was committed on 1991-12-21. Now (at least), changing the
2645 consistency label on such a state appears to have no useful effect in
2646 any of the places it is examined, which I enumerate below. The key
2647 point to understanding each item in this enumeration is that a state
2648 with an error transition is labelled consistent in the first place only
2649 if it has no rules, so the check cannot matter for states that have
2650 rules. (1) Labelling a state as inconsistent will cause set_conflicts
2651 to try to identify its conflicts, and a state must have *rules* to have
2652 conflicts. (2) Labelling a state as inconsistent will affect how
2653 action_row sets the default *rule* for the state. (3) Labelling a
2654 state as inconsistent will cause build_relations to add lookback edges
2655 to *rules* in that state.
2656 * src/state.h (struct state): Word the comment for member consistent
2657 more carefully.
2658
2659 2007-05-27 Joel E. Denny <jdenny@ces.clemson.edu>
2660
2661 Don't depend on C99 features.
2662 * src/conflicts.c (conflicts_update_state_numbers): Fix for-loop.
2663 * src/lalr.c (lalr_update_state_numbers): Fix for-loop.
2664 * src/reader.c (check_and_convert_grammar): Fix for-loop.
2665 * src/state.c (state_mark_reachable_states): Fix for-loop.
2666 (state_remove_unreachable_states): Fix for-loop.
2667
2668 Don't widen struct state with member reachable just to temporarily
2669 record reachability. Instead, use a local bitset.
2670 * src/state.h (struct state): Remove member.
2671 * src/state.c (state_new): Don't initialize it.
2672 (state_mark_reachable_states): Rename to...
2673 (state_record_reachable_states): ... this, and use bitset.
2674 (state_remove_unreachable_states): Use bitset.
2675
2676 2007-05-26 Joel E. Denny <jdenny@ces.clemson.edu>
2677
2678 * src/Makefile.am (yacc): Quote target action commands properly so
2679 that the yacc script isn't corrupt. Reported by Hans Aberg at
2680 <http://lists.gnu.org/archive/html/bug-bison/2007-05/msg00003.html>.
2681
2682 * data/glr.c (yylval): As in yacc.c, don't extern in the header for
2683 the case of pure parsers. Reported by Frans Englich at
2684 <http://lists.gnu.org/archive/html/help-bison/2007-05/msg00018.html>.
2685 * THANKS: Add Frans Englich.
2686
2687 * NEWS (2.3a+): In the %code entry, reference section `Bison
2688 Declaration Summary' from the manual now since the %code summary has
2689 moved there.

2691 in the rules section must be terminated by semicolons.
2692
2693 2007-05-20 Joel E. Denny <jdenny@ces.clemson.edu>
2694
2695 Extend the front-end API for %define variables to more completely

2707 muscle_percent_define_get to mimic the b4_percent_define_flag_if
2708 implementation more closely.
2709 (muscle_percent_define_invalid_value): New function.
2710 * src/muscle_tab.h (muscle_percent_define_get,
2711 muscle_percent_define_ifdef, muscle_percent_define_invalid_value):
2712 Prototype.
2713
2714 2007-05-07 Joel E. Denny <jdenny@ces.clemson.edu>
2715
2716 * NEWS (2.3a+): Mention yesterday's state-removal change.
2717 (2.3a): Remove the %language entry, which was added after 2.3a.

2722
2723 2007-05-06 Joel E. Denny <jdenny@ces.clemson.edu>
2724
2725 If conflict resolution makes states unreachable, remove those states,
2726 report rules that are then unused, and don't report conflicts in those
2727 states.
2728 * src/conflicts.c, src/conflicts.h (conflicts_update_state_numbers):
2729 New global function.

2752 used in the comments.
2753 (closure): Update for rename.
2754 * src/closure.h (nritemset): Update extern to...
2755 (nitemset): ... this.
2756 * src/lalr.c (LA): Fix a typo in comments.
2757 * src/print.c (print_core): Update for rename to nitemset.
2758 * src/print_graph.c (print_graph): Likewise.

2760
2761 2007-04-04 Paul Eggert <eggert@cs.ucla.edu>
2762
2763 * THANKS: Use ASCII for Sebastien Fricker's name. Bison source
2764 still sticks to ASCII. Sorry!
2765
2766 * README-hacking: New file, taken mostly from coreutils, with changes
2767 for Bison. Contains much of the contents of:

2814
2815 2007-03-07 Juan Manuel Guerrero <juan.guerrero@gmx.de>
2816
2817 DJGPP spefic issue. Inhibit the use of disallowed characters for
2818 file name genertion on Win98, WinXP, etc. These are |<>":?*\
2819 and concern testsuite case 46.
2820 * Makefile.am: djgpp/testsuite.sed added to EXTRA_DIST
2821 * djgpp/testsuite.sed: Inhibit the use of disallowed characters.
2822 * djgpp/config.bat: Inhibit the use of disallowed characters.
2823
2824 2007-03-02 Joel E. Denny <jdenny@ces.clemson.edu>

2826 Miscellaneous %define and %code cleanup.
2827 * data/bison.m4 (b4_percent_define_flag_if): Correct comments on how
2828 values are interpreted.
2829 * doc/bison.texinfo (Decl Summary): Clean up and extend %define
2830 documentation a little more.

2838 %define and %code directives.
2839
2840 Make it easy to share %define boolean variables between the front-end
2841 and back-end. Though not used yet, this will be useful in the future.
2842 * data/bison.m4 (b4_check_user_names): Rewrite comments to talk about
2843 Bison uses of names rather than just skeleton uses of names.
2844 (b4_percent_define_get, b4_percent_define_ifdef): Rename

2854
2855 For %define variables, report locations for invalid values and
2856 redefinitions.
2857 * data/bison.m4 (b4_percent_define_flag_if): Read
2858 b4_percent_define_loc(VARIABLE) to report the location of an invalid
2859 value for VARIABLE.
2860 (b4_percent_define_default): Save a special location in
2861 b4_percent_define_loc(VARIABLE) in case the default value for VARIABLE
2862 must later be reported as invalid.
2863 * src/muscle_tab.c (muscle_location_grow, muscle_location_decode): New
2864 functions.
2865 (muscle_percent_define_insert): Record the location of VARIABLE in
2866 muscle percent_define_loc(VARIABLE), and use it to report the previous
2867 location for a redefinition.
2868 (muscle_percent_define_flag_if): Update like b4_percent_define_flag_if.
2869 (muscle_percent_define_default): Update like b4_percent_define_default.
2870 (muscle_grow_user_name_list): Rename to...

2877
2878 2007-02-28 Joel E. Denny <jdenny@ces.clemson.edu>
2879
2880 * src/print.c (lookahead_set, state_default_rule): Remove.
2881 (print_reductions): Replace state_default_rule invocation with
2882 equivalent use of yydefact, which was computed in token_actions in
2883 tables.c.
2884 (print_results): Don't allocate lookahead_set.
2885
2886 2007-02-27 Paolo Bonzini <bonzini@gnu.org>
2887
2888 * data/lalr1.java: Prefix all private members with yy.
2889
2890 2007-02-24 Joel E. Denny <jdenny@ces.clemson.edu>
2891
2892 Use YYFPRINTF instead of fprintf where appropriate. Reported by
2893 Sebastien Fricker at
2894 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00035.html>.
2895 * THANKS: Add Sebastien Fricker.
2896 * data/glr.c, data/push.c, data/yacc.c (yy_reduce_print): Implement.
2897 * doc/bison.texinfo (Tracing): Make it clearer that YYFPRINTF must
2898 accept a variable number of arguments.
2899
2900 2007-02-19 Joel E. Denny <jdenny@ces.clemson.edu>
2901
2902 * bootstrap: Remove occurrences of .#bootmp from lib/Makefile.
2903
2904 2007-02-13 Juan Manuel Guerrero <juan.guerrero@gmx.de>

2907 * djgpp/config.sed: Adjustments concerning the use of autoconf 2.61.
2908 * djgpp/config.site: Adjustments concerning the use of autoconf 2.61.
2909
2910 2007-02-11 Paul Eggert <eggert@cs.ucla.edu>
2911
2912 Undo my 2007-02-07 change, switching back to the c-strcase module
2913 introduced in the 2007-02-03 change. Bruno Haible reported that
2914 the 2007-02-07 change would be dangerous in Turkish if we add a
2915 language whose name contains "i", since "i" is not lowercase "I"
2916 in Turkish.
2917 * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
2918 * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
2919 c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
2920 * m4/.cvsignore: Remove strcase.m4.
2921 * src/getargs.c: Revert 2007-02-07 change, as follows.
2922 Include c-strcase.h.
2923 (language_argmatch): Use c_strcasecmp rather than strcasecmp.
2924
2925 2007-02-11 Bruno Haible <bruno@clisp.org>
2926
2927 Enable the Java related testsuite tests when the only Java compiler
2928 found is a gcj < 4.3. Discussed at
2929 <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
2930 * configure.ac (gt_JAVACOMP): Don't specify a target_version.
2931
2932 2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
2933
2934 * data/Makefile.am: Update copyright date.
2935 * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
2936 yypstate_new returns NULL.
2937 (yypstate_new): Return NULL if malloc does.
2938 * src/reader.c (packgram): Move translation of rule actions from the
2939 beginning of packgram to...
2940 (check_and_convert_grammar): ... here right before packgram is invoked
2941 so it's easier to write more complete comments, and remove redundant
2942 code.
2943
2944 2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
2945
2946 As in semantic actions, make @$ in %initial-action, %destructor, and
2947 %printer imply %locations.
2948 * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
2949 scanning @$.
2950 * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
2951 (@$ in %initial-action implies %locations,
2952 @$ in %destructor implies %locations,
2953 @$ in %printer implies %locations): ... these new test cases.
2954
2955 2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
2956
2957 Undo most of the 2007-02-03 change, switching to the strcase module
2958 now that gnulib strcase has been fixed.
2959 * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
2960 * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
2961 c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
2962 * m4/.cvsignore: Add strcase.m4.
2963 * src/getargs.c: Revert 2007-02-03 change, as follows.
2964 Don't include c-strcase.h.
2965 (language_argmatch): Use strcasecmp rather than c_strcasecmp.
2966 strcasecmp has "unspecified behavior" outside the POSIX locale,
2967 but it works fine in practice if at least one argument is ASCII,
2968 as is the case in Bison.
2969
2970 2007-02-07 Paolo Bonzini <bonzini@gnu.org>
2971
2972 * tests/java.at: Skip tests if only one of javac/java is present.
2973 Reported by Joel E. Denny.
2974 * tests/atlocal.in: Adjust copyright years.
2975
2976 2007-02-05 Paolo Bonzini <bonzini@gnu.org>
2977
2978 * data/lalr1.java (Stack): Work around old verifiers that disallow
2979 access to the private fields of an inner class, from the outer class.
2980 We can make Stack's fields public because user code doesn't have access
2981 to the instance of Stack used by parse(). Reported by Paul Eggert.
2982
2983 2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
2984
2985 * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
2986 the right spot for these files?
2987 * bootstrap.conf (gnulib_modules): Add c-strcase.
2988 * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
2989 c-strncasecmp.c.
2990 * src/getargs.c: Include c-strcase.h.
2991 (language_argmatch): Use c_strcasecmp rather than strcasecmp,
2992 to avoid unspecified behavior.
2993
2994 2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
2995
2996 * doc/bison.texinfo (Decl Summary): Correct typo.
2997
2998 2007-01-30 Paolo Bonzini <bonzini@gnu.org>
2999
3000 * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
3001 Complain if the value does not match empty, "true" or "false".
3002 * data/c++.m4: Adjust default definitions of %define variables.
3003 * data/java.m4: Adjust default definitions of %define variables.
3004 * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
3005 to above behavior.
3006 * tests/input.at (Boolean %define variables): Test new behavior.
3007
3008 2007-01-29 Paolo Bonzini <bonzini@gnu.org>
3009

3032 2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
3033
3034 Clean up.
3035 * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
3036 at_directive_argv arguments so these no longer have to be global
3037 variables. Also, update the implementation for the following changes.
3038 (fail_for_at_directive_too_many_args,
3039 fail_for_at_directive_too_few_args): Add at_directive_name argument.
3040 (at_directive_name): Remove as at_directive_argv[0] will be used for
3041 this now.
3042 (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
3043 for the directive name.
3044 (at_directive_argc, at_directive_argv): Make these local within
3045 skel_lex instead of global.
3046 (INITIAL): Update directive start action for above changes.
3047 (SC_AT_DIRECTIVE_ARG): Rename to...

3050 (scan_skel): Move yylex_destroy to...
3051 (skel_scanner_free): ... here.
3052 * tests/skeletons.at (installed skeleton file name): Rename to...
3053 (installed skeleton file names): ... this.
3054
3055 2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
3056
3057 * ChangeLog: For changes in doc/bison.texinfo, consistently reference
3058 node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
3059 Summary" not "Directives".
3060 * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
3061 %code entry in "Decl Summary" rather than the one in "Table of Symbols"
3062 since the former is now the more complete one.
3063 (Prologue Alternatives): Likewise and do the same for %defines.
3064 (Table of Symbols): Add summary of %code, add summary of %define, and
3065 move full %code documentation to...
3066 (Decl Summary): ... here for consistency with other entries in these
3067 sections.
3068 Move %define entry in order to keep this list alphabetized.
3069 Reword %define entry a little to put less emphasis on the skeleton
3070 concept, which most users shouldn't have to think about.
3071
3072 2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
3073
3074 Adjust to recent gnulib changes.
3075 * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
3076 Add string.h, string_.h, unistd_.h, wchar_.h.
3077 * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
3078 * src/system.h: Don't include <stpcpy.h>; this is now done by
3079 <string.h>.
3080
3081 2007-01-23 Paolo Bonzini <bonzini@gnu.org>
3082
3083 Simplify implementation of unqualified %code, implement macros for
3084 uniform treatment of boolean %define flags. Document %define.
3085 * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
3086 b4_percent_code_ifdef): New.
3087 (b4_percent_code_get): Map unqualified %code to b4_percent_code().
3088 * data/c++.m4: Define default value for global_tokens_and_yystype.
3089 * data/glr.cc: Likewise.
3090 * data/location.cc: Use b4_percent_define_flag_if.
3091
3092 * doc/bison.texinfo (Decl Summary): Document %define.
3093
3094 * src/parse-gram.y (Unqualified %code): Change muscle name to
3095 b4_percent_code().
3096 (content.opt): Default to empty.
3097
3098 2007-01-17 Joel E. Denny <jdenny@ces.clemson.edu>
3099
3100 Implement support for relative and absolute skeleton file names.
3101 Discussed starting at
3102 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>.
3103 * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
3104 (Bison Options): Document in --skeleton entry.
3105 * src/output.c (output_skeleton): Use strncpy rather than strcpy since
3106 full_skeleton can't necessarily hold all of pkgdatadir.
3107 If the specified skeleton file name contains a `/', don't prepend
3108 pkgdatadir.
3109 * src/parse-gram.y (prologue_declaration): If the specified skeleton
3110 file name contains a `/', prepend the grammar file directory.
3111 * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at.
3112 * skeletons.at: New file.
3113 (relative skeleton file names): New test case.
3114 (installed skeleton file names): New test case.
3115 * tests/testsuite.at: Include skeletons.at.
3116
3117 * bootstrap: Update copyright to 2007.
3118
3119 2007-01-17 Paolo Bonzini <bonzini@gnu.org>
3120
3121 * bootstrap: Remove occurrences of .#bootmp from the files.
3122
3123 2007-01-17 Akim Demaille <akim@epita.fr>
3124
3125 * doc/bison.texinfo (Calc++ Parser): Don't try to alias
3126 nonterminals.
3127 Use per-type %printer.
3128

3139 2007-01-16 Akim Demaille <akim@epita.fr>
3140
3141 * doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an
3142 error code.
3143 (Calc++ Scanner): Exit with failure if we can't open the input
3144 file.
3145 Accept "-" standing for stdin.
3146 (Calc++ Top Level): Print the result only if the parsing was
3147 successful.
3148
3149 2007-01-16 Akim Demaille <akim@epita.fr>
3150
3151 * data/lalr1.cc (yy_reduce_print_): Add a missing end-of-line.
3152
3153 2007-01-15 Paolo Bonzini <bonzini@gnu.org>
3154 and Joel E. Denny <jdenny@ces.clemson.edu>
3155
3156 Clean up %define and %code implementation in M4 some. Most
3157 importantly, rename all related macros to be in the b4_percent_define
3158 and b4_percent_code namespaces. Also, complete support for `.' in
3159 %define variable names and %code qualifiers.
3160 * data/bison.m4 (b4_check_user_names): Check for special
3161 "SKELETON-NAMESPACE(name)" macros instead of using two nested
3162 m4_foreach loops.
3163 (b4_get_percent_define, b4_get_percent_code): Rename to...
3164 (b4_percent_define_get, b4_percent_code_get): ... these.
3165 Extend documentation with examples.
3166 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
3167 b4_percent_define_skeleton_variables and
3168 b4_percent_code_skeleton_qualifiers.
3169 Expect any value for the %define variable `foo' to be stored in the
3170 macro named `b4_percent_define(foo)'; expect any %code blocks for the
3171 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
3172 expect any unqualified %code blocks to be stored in a macro named
3173 `b4_percent_code_unqualified'.
3174 Use m4_indir so that %define variable names and %code qualifiers can
3175 contain `.', which is allowed by the grammar parser.
3176 (b4_percent_define_default): New macro to set a default value for a
3177 %define variable.
3178 (m4_wrap): Update wrapped code, and fix some underquoting.
3179 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
3180 Expect grammar uses of %define variables and %code qualifiers to be
3181 defined in b4_percent_define_user_variables and
3182 b4_percent_code_user_qualifiers.
3183 * data/c++.m4: Use b4_percent_define_default rather than
3184 m4_define_default. Fix some underquoting. Skeleton usage of %define
3185 variable define_location_comparison now implies skeleton usage of
3186 %define variable filename_type.
3187 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3188 data/push.c, data/yacc.c: Update macro names.
3189 * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
3190 muscle names.
3191
3192 2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
3193
3194 DJGPP specific issues.
3195
3196 * djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific
3197 default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
3198
3199 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3200
3201 * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
3202 run parsers in all tests so that Valgrind is invoked during
3203 maintainer-check-valgrind.
3204 (Duplicate representation of merged trees): Free all semantic values.
3205 (Duplicated user destructor for lookahead): Likewise.
3206
3207 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3208
3209 * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
3210 command-line prefix.
3211 * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
3212 ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
3213 miss Valgrind messages.
3214 (Exploding the Stack Size with Malloc): Likewise.
3215
3216 2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
3217
3218 Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
3219 locals. Reported by Juan Manuel Guerrero at
3220 <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>.
3221 * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if.
3222 Fix some indentation also.
3223 * tests/torture.at (Exploding the Stack Size with Alloca): Add comment
3224 explaining this issue.
3225
3226 2007-01-09 Paolo Bonzini <bonzini@gnu.org>
3227 and Joel E. Denny <jdenny@ces.clemson.edu>
3228
3229 Simplify union and prologue handling, and escape union and lex/parse
3230 params with digraphs.
3231 * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
3232 values to the empty string since these are no longer guaranteed
3233 initialized by the front-end.
3234 * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
3235 braces around b4_user_stype since this is no longer done by the
3236 front-end.
3237 * src/files.c, src/files.h (pre_prologue_obstack,
3238 post_prologue_obstack): Remove.
3239 * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
3240 comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
3241 with digraphs. This fixes lex params and parse params.
3242 * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
3243 * src/output.c (prepare): Remove muscle insertion of the prologues.
3244 (output): Remove freeing of pre_prologue_obstack and
3245 post_prologue_obstack.
3246 * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
3247 than prologue_augment for prologue parsing so you don't need prologue
3248 obstacks.
3249 (grammar_declaration): For %union RHS, use `braceless' instead of
3250 "{...}" so that braces are already stripped and code is escaped with
3251 digraphs.
3252 * src/reader.c (prologue_augment): Remove.
3253 (reader): Remove initialization of pre_prologue_obstack and
3254 post_prologue_obstack.
3255 * src/reader.h (prologue_augment): Remove.
3256
3257 * data/c.m4: Remove stray parenthesis.
3258
3259 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3260
3261 Remove quotes from variables names in %define directives and from
3262 qualifiers in %code directives, and restrict the characters that are
3263 allowed in them to M4-friendly ones. For %define, continue to support
3264 the quoted form as a deprecated feature. Discussed starting at
3265 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
3266 * NEWS (2.3a+): Add entry for the change to %define. Update entry for
3267 %code.
3268 * doc/bison.texinfo (Prologue Alternatives): Update.
3269 (Decl Summary): In %defines entry, update mention of `%code requires'
3270 and `%code provides'.
3271 (C++ Location Values): Update %define uses.
3272 (Calc++ Parser Interface): Likewise.
3273 (Calc++ Parser): Likewise, and update `%code requires' uses.
3274 (Table of Symbols): Update %code documentation.
3275 * src/parse-gram.y (prologue_declaration): For %define variables, use
3276 `variable' instead of `STRING'.
3277 (grammar_declaration): For %code qualifiers, use `ID' instead of
3278 `STRING'.
3279 (variable): New nonterminal that takes an `ID' or a `STRING'.
3280 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code
3281 and %define uses.
3282 * tests/calc.at (_AT_DATA_CALC_Y): Update %define use.
3283 * tests/input.at (Reject unused %code qualifiers): Update %code uses.
3284 (%define errors): Update %define uses.
3285
3286 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3287
3288 * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING
3289 instead of muscle_insert for %define values so that M4-special
3290 characters are replaced with digraphs.
3291 * tests/input.at (%define errors): Extend to check weird values.
3292
3293 2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
3294
3295 Instead of having skeletons declare all valid %define variables and
3296 %code qualifiers, provide macros that retrieve the associated values
3297 and build these lists automatically. Thus Bison will now warn when a
3298 variable or qualifier is not used by the skeleton in the current
3299 invocation regardless of whether it might sometimes be used by that
3300 skeleton in other invocations. Also, move all %define value macros to
3301 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
3302 form, which is replaced by %code.
3303 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
3304 (b4_check_user_names): ... this, and change the series of valid name
3305 arguments to a single list argument for names used in the skeleton
3306 similar to the existing list argument for names used in the grammar.
3307 Warn instead of complaining.
3308 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
3309 values and %code code, to format %code code properly, and to build
3310 lists of all %define variables and %code qualifiers used in the
3311 skeleton: b4_skeleton_percent_define_variables and
3312 b4_skeleton_percent_code_qualifiers.
3313 (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
3314 Remove, and...
3315 (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
3316 the skeleton names lists can finish building first. In place of
3317 b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
3318 expect the lists b4_user_percent_define_variables and
3319 b4_user_percent_code_qualifiers.
3320 * data/c++.m4: Where setting default values for b4_parser_class_name,
3321 b4_location_type, b4_filename_type, b4_namespace, and
3322 b4_define_location_comparison, update their names to the
3323 b4_percent_define_ namespace.
3324 * data/glr.c: Don't use b4_check_percent_define_variables and
3325 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3326 * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
3327 (b4_parser_class_name, b4_namespace): Define these using
3328 b4_get_percent_define for parser_class_name and namespace.
3329 * data/location.cc: Use b4_get_percent_define.
3330 * data/push.c: Don't use b4_check_percent_define_variables and
3331 b4_check_percent_code_qualifiers. Use b4_get_percent_code.
3332 * data/yacc.c: Likewise, and don't call m4_exit in
3333 b4_use_push_for_pull_if or m4_wrap code will never execute.
3334 * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
3335 Rename to...
3336 (muscle_grow_user_name_list): ... this for consistency with the
3337 terminology used in bison.m4.
3338 * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
3339 %define variable names, and rename muscle used_percent_define_variables
3340 to user_percent_define_variables.
3341 (grammar_declaration): Rename muscle used_percent_code_qualifiers to
3342 user_percent_code_qualifiers.
3343 (content): Remove.
3344 (content.opt): Replace content RHS with STRING RHS so %define "NAME"
3345 {CODE} form is no longer accepted.
3346 * tests/input.at (Reject bad %code qualifiers): Rename to...
3347 (Reject unused %code qualifiers): ... this, and update test output.
3348 (%define error): Update test output.
3349
3350 2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
3351
3352 Check for unrecognized %define variables similar to checking for
3353 unrecognized %code qualifiers. Check for redefined %define variables.
3354 * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
3355 generalizes...
3356 (b4_check_percent_code_qualifiers): ... this, which now wraps it.
3357 (b4_check_percent_define_variables): New, also wraps it.
3358 * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
3359 variables using b4_check_percent_define_variables.
3360 * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
3361 all those exercised in the test suite and all those listed in the
3362 `Default values' section of c++.m4. Are there others?
3363 * data/push.c, data/yacc.c: Declare no valid %define variables.
3364 * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
3365 similar to muscle_find, but it works even when the muscle stores a
3366 const value.
3367 (muscle_grow_used_name_list): New function for constructing the used
3368 name list muscles that b4_check_for_unrecognized_names requires.
3369 * src/parse-gram.y (prologue_declaration): Warn if a variable is
3370 %define'd more than once. Define the b4_used_percent_define_variables
3371 muscle with muscle_grow_used_name_list.
3372 (grammar_declaration): Abbreviate %code code with
3373 muscle_grow_used_name_list.
3374 * tests/input.at (%define errors): New.
3375
3376 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3377
3378 Provide warn_at, complain_at, and fatal_at function callbacks to the
3379 skeletons, and use this for %code qualifier complaints.
3380 * data/bison.m4 (b4_error_at): New, invoked by...
3381 (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
3382 the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
3383 @fatal_at(...@) directives.
3384 (b4_check_percent_code_qualifiers): Rewrite to expect locations for
3385 qualifiers in b4_used_percent_code_qualifiers and to use
3386 b4_complain_at.
3387 * src/location.c, src/location.h (boundary_set_from_string): New global
3388 function.
3389 * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
3390 function.
3391 * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
3392 to b4_used_percent_code_qualifiers.
3393 * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
3394 function.
3395 (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
3396 (lineno): Rename to...
3397 (out_lineno): ... this so I don't misunderstand it again.
3398 (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
3399 here; these newlines are in the input but not the output file.
3400 (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
3401 (at_directive_perform): ... this new static function, and add handling
3402 of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
3403 directives.
3404 * tests/input.at (Reject bad %code qualifiers): Update test output with
3405 locations and extend.
3406
3407 * tests/output.at (Output file name: [, Output file name: ]): Remove
3408 bogus comment about these tests failing.
3409
3410 2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
3411
3412 Clean up b4_check_percent_code_qualifiers a little.
3413 * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
3414 in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
3415 documentation and add examples.
3416 * src/parse-gram.y (grammar_declaration): Double-M4-quote those
3417 qualifiers here.
3418
3419 2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
3420
3421 Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
3422 unreliable -- especially when they're hidden inside another macro.
3423 * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
3424 data/c.m4: Remove m4_divert(-1).
3425 * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
3426 data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
3427 m4_divert_push(0) and m4_divert_pop(0).
3428 * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
3429 an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
3430 pushed and popped by m4sugar, should be first on the stack.
3431
3432 Provide warn, complain, and fatal function callbacks to the skeletons.
3433 This provides more flexibility than m4_fatal, improves the error
3434 message format, and captures messages for translation. Discussed
3435 starting at
3436 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
3437 * data/bison.m4 (b4_error): New, invoked by...
3438 (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
3439 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
3440 directives. Because these M4 macros might be called when the current
3441 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
3442 the previous removal of uses of m4_divert, which caused trouble.
3443 (b4_check_percent_code_qualifiers): Use b4_complain instead of
3444 m4_fatal to report unrecognized %code qualifiers.
3445 * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
3446 push parser requests.
3447 * data/glr.c: Use b4_complain instead of m4_fatal to report
3448 non-deterministic push parser requests.
3449 Update @output usage to @output(...@) form.
3450 * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
3451 report missing %defines. Update @output usage to @output(...@) form.
3452 * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
3453 @output(...@) form.
3454 * src/main.c (main): Invoke skel_scanner_free.
3455 * src/scan-skel.h (skel_scanner_free): Prototype new function.
3456 * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
3457 obstack_for_string from flex-scanner.h.
3458 (YY_DECL): Use to declare skel_lex static.
3459 (decode_at_digraphs): Remove; now handled in the new
3460 SC_AT_DIRECTIVE_ARG start condition.
3461 (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
3462 functions.
3463 (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
3464 at_directive_argv): New static globals.
3465 (INITIAL): Use fail_for_invalid_at.
3466 Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
3467 recognize the start of a generalized `@directive(...@)' form and
3468 start...
3469 (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
3470 directive args (using the new obstack_for_string), to decode the
3471 contained @ diagraphs, and to perform the directive. It recognizes
3472 @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
3473 @output(...@).
3474 (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
3475 SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
3476 `@,'.
3477 (scan_skel): Initialize obstack_for_string on the first call.
3478 (skel_scanner_free): New function to free obstack_for_string.
3479 * tests/input.at (Reject bad %code qualifiers): Update test output.
3480
3481 2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>
3482
3483 Consolidate the 4 prologue alternative directives (%code, %requires,
3484 %provides, and %code-top) into a single %code directive with an
3485 optional qualifier field. Discussed at
3486 <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00012.html>.
3487 * NEWS (2.3a+): Rewrite the existing entry for the prologue
3488 alternatives.
3489 * doc/bison.texinfo (Prologue Alternatives): Update.
3490 (Decl Summary): Update to %code "requires" and %code "provides".
3491 (Calc++ Parser): Update to %code "requires".
3492 (Table of Symbols): Remove entries for %requires, %provides, and
3493 %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
3494 * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
3495 are replaced by b4_percent_code_provides and b4_percent_code_requires,
3496 which are skeleton-specific.
3497 (b4_check_percent_code_qualifiers): New. A skeleton can use this to
3498 declare what %code qualifiers it supports and to complain if any other
3499 qualifiers were used in the grammar.
3500 * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
3501 and b4_user_code([b4_percent_code_provides]) in place of
3502 b4_user_requires and b4_user_provides.
3503 * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
3504 Add b4_user_code([b4_percent_code_top]) and
3505 b4_user_code([b4_percent_code]).
3506 Invoke b4_check_percent_code_qualifiers.
3507 * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3508 PERCENT_REQUIRES): Remove.
3509 (grammar_declaration): Remove RHS's for %code-top, %provides, and
3510 %requires. Rewrite the %code RHS as the unqualified form defining the
3511 muscle b4_percent_code. Add another RHS for the qualified %code form,
3512 which defines muscles of the form b4_percent_code_QUALIFIER and the
3513 b4_used_percent_code_qualifiers muscle.
3514 * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
3515 PERCENT_REQUIRES): Remove.
3516 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
3517 %code "requires" and %code "provides".
3518 * tests/input.at (Reject bad %code qualifiers): New.
3519
3520 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3521
3522 Use the new code_props interface for destructors and printers.
3523 * src/symtab.h (symbol, semantic_type): Remove destructor_location and
3524 printer_location members, and change the type of the destructor and
3525 printer members to code_props.
3526 (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,
3527 symbol_printer_get, semantic_type_destructor_set,
3528 semantic_type_printer_set, default_tagged_destructor_set,
3529 default_tagless_destructor_set, default_tagged_printer_set,
3530 default_tagless_printer_set): Use code_props in arguments and return
3531 types in place of char const * and location.
3532 (symbol_destructor_location_get, symbol_printer_location_get): Remove
3533 since the locations are now contained in the return of
3534 symbol_destructor_get and symbol_printer_get.
3535 * src/output.c (symbol_destructors_output, symbol_printers_output):
3536 Replace with...
3537 (symbol_code_props_output): ... this to eliminate duplicate code.
3538 (output_skeleton): Update to use symbol_code_props_output.
3539 * src/reader.c (symbol_should_be_used): Update use of
3540 symbol_destructor_get.
3541 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
3542 Update uses of the various _destructor_set and _printer_set functions.
3543 * src/symtab.c: (default_tagged_destructor_location,
3544 default_tagless_destructor_location, default_tagged_printer_location,
3545 default_tagless_printer_location): Remove since we...
3546 (default_tagged_destructor, default_tagless_destructor,
3547 default_tagged_printer, default_tagless_printer): ... change the type
3548 of these to code_props.
3549 (symbol_new, semantic_type_new, symbol_destructor_set,
3550 semantic_type_destructor_set, symbol_destructor_get,
3551 symbol_printer_set, semantic_type_printer_set, symbol_printer_get,
3552 symbol_check_alias_consistency, default_tagged_destructor_set,
3553 default_tagless_destructor_set, default_tagged_printer_set,
3554 default_tagless_printer_set): Update.
3555 (symbol_destructor_location_get, symbol_printer_location_get): Remove.
3556 (SYMBOL_CODE_PRINT): New similar to SYMBOL_ATTR_PRINT but for
3557 code_props members.
3558 (symbol_print): Use SYMBOL_CODE_PRINT.
3559
3560 2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
3561
3562 Use the new code_props interface for rule actions.
3563 * src/symlist.h (symbol_list): Replace action, action_location, and
3564 used members with a code_props action_props member.
3565 * src/reader.c (symbol_should_be_used, grammar_rule_check,
3566 grammar_midrule_action, grammar_current_rule_merge_set,
3567 grammar_current_rule_symbol_append, packgram): Update.
3568 * src/scan-code.h (translate_rule_action): Remove, no longer used.
3569 * src/scan-code.l (handle_action_dollar): Update.
3570 (translate_rule_action): Remove, no longer used.
3571 * src/symlist.c (symbol_list_sym_new, symbol_list_syms_print): Update.
3572
3573 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3574
3575 Use the new code_props interface in parse-gram.y.
3576 * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
3577 Update all uses of translate_* functions to use the new code_props
3578 interface and to use gram_scanner_last_string_free and
3579 code_scanner_last_string_free where possible.
3580 (grammar_declaration): symbol_list_destructor_set and
3581 symbol_list_printer_set now perform the translation, so don't do it
3582 here. Use gram_scanner_last_string_free where possible.
3583 * src/scan-code.h, src/scan-code.l (translate_symbol_action,
3584 translate_code): Remove, no longer used.
3585 * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
3586 symbol_list_printer_set): Perform code translation here rather than
3587 depending on the caller to do so.
3588
3589 * src/symlist.h (struct symbol_list): Correct some documentation typos.
3590 * src/scan-gram.h (gram_last_string): Remove declaration.
3591 * src/scan-gram.l (last_string): Declare it static.
3592
3593 2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
3594
3595 Encapsulate code properties and related functionality for the various
3596 destructors, printers, and actions into a code_props structure and
3597 interface. This patch merely implements code_props in scan-code.h and
3598 scan-code.l. Future patches will rewrite other modules to use it.
3599 Discussed starting at
3600 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
3601 * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
3602 consistently initialize const structs that have an empty location
3603 field.
3604 * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
3605 to ensure consistency.
3606 * src/scan-code.h (code_props): New structure.
3607 (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
3608 function, macro, and const global variable for initializing a
3609 code_props with no code.
3610 (code_props_plain_init, code_props_symbol_action_init,
3611 code_props_rule_action_init, code_props_translate_code): The rest of
3612 the new code_props functional interface. Among other things, the init
3613 functions set the code_props kind field so that
3614 code_props_translate_code will know whether to behave like
3615 translate_symbol_action, translate_rule_action, or translate_code.
3616 These old translate functions must remain until all other modules are
3617 updated to use the new code_props interface.
3618 (code_scanner_last_string_free): New function similar to
3619 gram_scanner_last_string_free.
3620 (code_scanner_free): Add documentation.
3621 * src/scan-code.l: Implement the new interface.
3622 (code_lex): Make it static, add a code_props* argument, and remove the
3623 rule argument.
3624 (last_string): New static global similar to the one in scan-gram.l.
3625 (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
3626 instead of rule.
3627 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
3628 code_props since Bison may one day use this information for destructors
3629 and printers.
3630 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
3631 (handle_action_dollar): Use symbol_list_n_get and set used flag
3632 directly since symbol_list_n_used_set is removed.
3633 (translate_action): Add a code_props* argument and remove the rule,
3634 action, and location arguments. Pass the code_props* on to code_lex.
3635 (translate_rule_action, translate_symbol_action, translate_code):
3636 Rewrite as wrappers around the new code_props interface.
3637 * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
3638 it would eventually need to break the encapsulation of code_props.
3639
3640 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3641
3642 * etc/.cvsignore: New.
3643
3644 2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
3645
3646 Add maintainer-push-check to run maintainer-check using push parsing in
3647 place of pull parsing where available.
3648 * Makefile.am (maintainer-push-check): New.
3649 * data/bison.m4 (b4_use_push_for_pull_if): New.
3650 * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
3651 appropriately based on their existing values.
3652 (yypush_parse): Don't print push-parser-specific diagnostics if push
3653 parsing is being used in place of pull parsing.
3654 * data/yacc.c: If push parsing should replace pull parsing, redirect to
3655 push.c.
3656 * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
3657 variable, and insert b4_use_push_for_pull_flag into muscles.
3658 * tests/Makefile.am (maintainer-push-check): New.
3659
3660 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3661
3662 * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
3663 (whether successful or failed) so that yypush_parse can be invoked
3664 again to start a new parse using the same yypstate.
3665 * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
3666 check multiple yypull_parse invocations on the same yypstate. For pull
3667 mode, extend to check multiple yyparse invocations.
3668 (Exploding the Stack Size with Alloca): Extend to try with
3669 %push-pull-parser.
3670 (Exploding the Stack Size with Malloc): Likewise.
3671
3672 * tests/calc.at (Simple LALR Calculator): Don't specify
3673 %skeleton "push.c" since %push-pull-parser implies that now.
3674 * tests/headers.at (export YYLTYPE): Don't check for the push
3675 declarations. Otherwise, this test case can't be used to see if push
3676 mode can truly emulate pull mode.
3677 * tests/input.at (Torturing the Scanner): Likewise.
3678 * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
3679 (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
3680 AT_YACC_IF, which now includes the case of push mode since %skeleton
3681 need not be used for push mode. This will be more intuitive once
3682 push.c is renamed to yacc.c.
3683
3684 2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
3685
3686 For push mode, convert yyparse from a macro to a function, invoke yylex
3687 instead of passing a yylexp argument to yypull_parse, and don't
3688 generate yypull_parse or yyparse unless %push-pull-parser is declared.
3689 Discussed starting at
3690 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
3691 * data/bison.m4 (b4_pull_if): New.
3692 * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
3693 * data/push.c: Improve M4 quoting a little.
3694 (b4_generate_macro_args, b4_parenthesize): Remove.
3695 (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
3696 any time a pull parser is requested.
3697 Don't #define this as a wrapper around yypull_parse. Instead, when
3698 both push and pull are requested, make it a function that does that
3699 same thing.
3700 (yypull_parse): If there's a b4_prefix, #define this to
3701 b4_prefix[pull_parse] when both push and pull are requested.
3702 Don't define this as a function unless both push and pull are
3703 requested.
3704 Remove the yylexp argument and hard-code yylex invocation instead.
3705 * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
3706 %push-parser.
3707 * src/getargs.c (pull_parser): New global initialized to true.
3708 * getargs.h (pull_parser): extern it.
3709 * src/output.c (prepare): Insert pull_flag muscle.
3710 * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
3711 (prologue_declaration): Set both push_parser and pull_parser = true for
3712 %push-pull-parser. Set push_parser = true and pull_parser = false for
3713 %push-parser.
3714 * src/scan-gram.l: Don't accept %push_parser as an alternative to
3715 %push-parser since there's no backward-compatibility concern here.
3716 Scan %push-pull-parser.
3717 * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
3718 instead of %push-parser.
3719 * tests/headers.at (export YYLTYPE): Make yylex static, and don't
3720 prototype it in the module that calls yyparse.
3721 * tests/input.at (Torturing the Scanner): Likewise.
3722 * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
3723
3724 2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
3725
3726 Update etc/bench.pl. Optimize push mode a little (the yyn change
3727 deserves most of the credit).
3728 * Makefile.am (SUBDIRS): Add etc subdirectory.
3729 * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
3730 * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
3731 yytoken, yyval, and yyloc declarations to...
3732 (yyparse or yypush_parse): ... here to improve performance. For
3733 yypush_parse invocations after the first, be sure to assign yyn its old
3734 value again.
3735 (yypstate_new): Don't bother initializing the yyresult field since the
3736 initial value isn't used.
3737 (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
3738 remove the #define that, in push mode, set it to yyps->NAME.
3739 * etc/Makefile.am: New.
3740 * etc/bench.pl: Remove and build it instead from...
3741 * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
3742 "tests/bison" from the build directory by default rather than just
3743 invoking "bison" from $PATH.
3744 (calc_grammar): Update push parser code: don't declare yylval globally,
3745 don't define yyparse_wrapper, and don't #define yyparse.
3746 (bench_grammar): Update to check all working combinations of yacc.c,
3747 push.c, impure, pure, pull, and push.
3748
3749 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3750
3751 For push mode, add pull wrappers around yypush_parse.
3752 * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
3753 (yypull_parse): New function wrapping yypush_parse.
3754 (yyparse): New #define wrapping yypull_parse.
3755 * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
3756 is declared.
3757 * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
3758 prototype yylex in the module that calls yyparse, and don't prototype
3759 yyparse there. Otherwise, the yyparse expansion won't compile.
3760 * tests/input.at (Torturing the Scanner): Likewise.
3761
3762 2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
3763
3764 Enable push parsers to operate in impure mode. Thus, %push-parser no
3765 longer implies %pure-parser. The point of this change is to move
3766 towards being able to test the push parser code by running the entire
3767 test suite as if %push-parser had been declared.
3768 * data/push.c (yypush_parse): For impure mode, remove the
3769 yypushed_char, yypushed_val, and yypushed_loc arguments.
3770 Instead, declare these as local variables initialized to the global
3771 yychar, yylval, and yylloc.
3772 For the first yypush_parse invocation only, restore the initial values
3773 of these global variables when it's time to read a token since they
3774 have been overwritten.
3775 * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
3776 %push-parser.
3777 * tests/calc.at (Simple LALR(1) Calculator): Always declare
3778 %pure-parser along with %push-parser since this test case was designed
3779 for pure push parsers.
3780 * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
3781 (AT_YACC_OR_PUSH_IF): New.
3782 (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
3783 add a note that it's still wrong for some cases (as it has been for a
3784 while).
3785 (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
3786 %push-parser no longer implies %pure-parser.
3787
3788 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3789
3790 Remove some unnecessary differences between the pull parser code and
3791 the push parser code. This patch enables yynerrs in push mode.
3792 * data/push.c: Reformat M4 a little.
3793 (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
3794 (b4_declare_scanner_communication_variables): Don't omit yynerrs just
3795 because push mode is on. Instead, if pure mode is on, move yynerrs
3796 to...
3797 (b4_declare_parser_state_variables): ... here.
3798 (yynerrs, yyerror_range): For push mode, #define each NAME in this list
3799 to yyps->NAME so it can be used in yypush_parse.
3800 (yypush_parse): Don't omit uses of yynerrs in push mode.
3801
3802 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3803
3804 Fix bug such that the first pushed token's value and location are
3805 sometimes overwritten (sometimes by %initial-action) before being used.
3806 * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
3807 yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
3808 For the first yypush_parse invocation, initialize yychar to YYEMPTY to
3809 more closely mimic the pull parser logic.
3810 Don't copy the pushed token to yychar, yylval, and yylloc until it's
3811 time to read a token, which is after any initialization of yylval and
3812 yylloc.
3813 (gottoken): Rename label to...
3814 (yyread_pushed_token): ... for clarity and to avoid infringing on the
3815 user namespace.
3816
3817 2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
3818
3819 Rearrange initialization of the parser state variables so that the
3820 skeleton doesn't have to have a copy for pull mode and another for push
3821 mode. This patch also fixes at least a bug such that yylloc was not
3822 initialized (with b4_location_initial_line and
3823 b4_location_initial_column) upon calling yypush_parse. However, that
3824 initialization now overwrites the first token's location;
3825 %initial-action assigning @$ already did the same thing, and both bugs
3826 will be fixed in a later patch.
3827 * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
3828 (b4_declare_parser_state_variables): Remove initialization of yytoken,
3829 yyss, yyvs, yyls, and yystacksize.
3830 (yypstate_new): Remove initialization of some yypstate fields: yystate,
3831 yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
3832 yylsp.
3833 (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
3834 yyps->NAME so it can be used in yypush_parse.
3835 (yyparse or yypush_parse): For yypush_parse, don't print the
3836 "Starting parse" diagnostic for invocations after the first.
3837 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
3838 yypush_parse, only do it for the first invocation.
3839 Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
3840 initialization to occur in yypush_parse but only on the first
3841 invocation.
3842
3843 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3844
3845 * data/push.c: Add CPP guards around push parser declarations in both
3846 the header and the code file.
3847 In the code file, move the push parser declarations to the same place
3848 they appear in the header file.
3849 Clean up the M4 some, especially the inconsistent underquoting in
3850 some b4_c_function_def and b4_c_function_decl uses.
3851
3852 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3853
3854 Encapsulate the push parser state variables into an M4 macro so the
3855 push skeleton doesn't have to list them again for pull mode's yyparse.
3856 For push mode, remove yypush_parse's local equivalents of these
3857 variables to eliminate unnecessary copying between the two sets at
3858 run-time. This patch also fixes at least a bug related to multiple
3859 %initial-action invocations in push mode.
3860 * data/push.c (b4_declare_parser_variables): Rename to...
3861 (b4_declare_scanner_communication_variables): ... this for clarity and
3862 update both uses.
3863 (b4_declare_yyparse_variables): Remove and move its contents to the one
3864 spot where it was invoked.
3865 (b4_declare_parser_state_variables): New macro containing the parser
3866 state variables required by push mode.
3867 (struct yypstate): Replace all fields but yynew with
3868 b4_declare_parser_state_variables.
3869 (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
3870 yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
3871 each NAME in this list to yyps->NAME so it can be used in yypush_parse.
3872 (yyparse or yypush_parse): For yyparse in pull mode, replace local
3873 parser state variable declarations with
3874 b4_declare_parser_state_variables.
3875 Don't initialize parser state variables when calling yypush_parse since
3876 yypstate_new already does that.
3877 Invoke the user's initial action only upon the first yypush_parse
3878 invocation.
3879 Remove all code that copies between the local parser state variables
3880 and the yypstate.
3881
3882 2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
3883
3884 * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
3885 prevent a name collision in a future patch where these names will
3886 sometimes be #define'd.
3887 (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
3888 since it no longer has the same name as the existing argument.
3889 (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
3890
3891 2006-12-19 Paolo Bonzini <bonzini@gnu.org>
3892 and Joel E. Denny <jdenny@ces.clemson.edu>
3893
3894 * doc/bison.texinfo (Decl Summary): In the %language entry, mention
3895 that the argument is case-insensitive, and there's no `=' here.
3896 For the %skeleton entry, mention that %language is better.
3897 (Bison Options): Likewise for --language and --skeleton. Move the
3898 --skeleton entry so that the `Tuning the parser' section is sorted
3899 alphabetically on long options.
3900 (C++ Bison Interface): Don't use the word skeleton. Don't explain the
3901 %language directive in detail here; cross-reference the %language
3902 documentation instead.
3903 (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
3904 `%require "2.3b"' so that the example is always up-to-date.
3905 (Table of Symbols): Add entries for %language and %skeleton.
3906 * examples/extexi (normalize): Instead of replacing every %require
3907 argument with the current Bison version, just substitute for
3908 `@value{VERSION}'. This guarantees that we're testing what actually
3909 appears in the documentation.
3910 * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
3911 rather than `@VERSION@'.
3912
3913 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3914
3915 * NEWS: Reword the %language news a bit, and put it earlier.
3916
3917 * src/getargs.c (skeleton_arg): Last arg is now location const *.
3918 Rewrite to simplify the logic.
3919 (language_argmatch): Likewise.
3920 (program_name): We now own this var.
3921 * src/getargs.h (struct bison_language): Use char[] rather than
3922 const char *.
3923
3924 * doc/bison.texinfo (Decl Summary, Bison Options): Don't claim
3925 Java is supported.
3926 * src/complain.c (program_name): Remove decl; no longer needed.
3927 * src/main.c (program_name): Remove; now belongs to getargs.
3928
3929 2006-12-18 Paolo Bonzini <bonzini@gnu.org>
3930
3931 * NEWS: Document %language.
3932
3933 * data/Makefile.am (dist_pkgdata_DATA): Add c-skel.m4, c++-skel.m4.
3934
3935 * data/c-skel.m4, data/c++-skel.m4: New files.
3936 * data/glr.c: Complain on push parsers.
3937
3938 * doc/bison.texinfo (C++ Parser Interface): Prefer %language
3939 over %skeleton.
3940 (Decl Summary): Document %language and %skeleton.
3941 (Command line): Document -L.
3942
3943 * examples/extexi: Rewrite %require directive.
3944 * examples/calc++/Makefile.am: Pass VERSION to extexi.
3945
3946 * src/files.c (compute_exts_from_gc): Look in language structure
3947 for .y extension.
3948 (compute_file_name_parts): Check whether .tab should be added.
3949 * src/getargs.c (valid_languages, skeleton_prio, language_prio):
3950 (language, skeleton_arg, language_argmatch): New.
3951 (long_options): Add --language.
3952 (getargs): Use skeleton_arg, add -L/--language.
3953 * src/getargs.h: Include location.h.
3954 (struct bison_language, language, skeleton_arg, language_argmatch): New.
3955 * src/output.c (prepare): Pick default skeleton from struct language.
3956 Don't dispatch C skeletons here.
3957 * src/parse-gram.y (PERCENT_LANGUAGE): New.
3958 (prologue_declaration): Add "%language" rule, use skeleton_arg.
3959 * src/scan-gram.l ("%language"): New rule.
3960
3961 * tests/calc.at: Test %skeleton and %language.
3962 * tests/local.at (AT_SKEL_CC_IF): Look for %language.
3963 (AT_GLR_IF): Look for %skeleton "glr.cc".
3964 (AT_LALR1_CC_IF, AT_GLR_CC_IF): Rewrite.
3965 (AT_YACC_IF): Reject %language.
3966
3967 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
3968
3969 * src/symtab.h (struct semantic_type): Remove the tag 'semantic_type',
3970 since it wasn't used; only the typedef name 'semantic_type' is needed.
3971 Also, omit trailing white space.
3972
3973 * bootstrap: Sync from coreutils.
3974 (gnulib_extra_files): Add build-aux/announce.gen.
3975 (slurp): Adjust .gitignore files like .cvsignore files.
3976 * build-aux/announce-gen: Remove from CVS, since bootstrap
3977 now creates this.
3978
3979 2006-12-16 Joel E. Denny <jdenny@ces.clemson.edu>
3980
3981 Make %push-parser imply %pure-parser. This fixes several bugs; see
3982 <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00148.html>.
3983 * src/parse-gram.y (prologue_declaration): For %push-parser, also set
3984 pure_parser = true.
3985 * data/push.c: Don't bother testing b4_push_if when deciding whether
3986 to expand b4_declare_parser_variables globally.
3987 (yypush_parse): Likewise in here.
3988
3989 * data/push.c (yypush_parse): Add b4_parse_param to arguments.
3990 (yy_reduce_print): Reformat M4 for readability.
3991
3992 2006-12-15 Bob Rossi <bob@brasko.net>
3993 and Joel Denny <jdenny@ces.clemson.edu>
3994
3995 * data/push.c (yypstate): Add typedef, and update all uses of
3996 struct yypstate to just yypstate.
3997 * tests/calc.at (_AT_DATA_CALC_Y): Update here as well.
3998
3999 2006-12-14 Bob Rossi <bob@brasko.net>
4000
4001 * data/push.c (yypush_parse): Declare prototype regardless of
4002 %locations option.
4003
4004 2006-12-14 Bob Rossi <bob@brasko.net>
4005
4006 * data/push.c (yyparse): Remove the prototype and the #define when in
4007 push-parser mode.
4008
4009 2006-12-13 Bob Rossi <bob@brasko.net>
4010
4011 * data/push.c (yypstate_init): Rename to...
4012 (yypstate_new): ... this and use b4_c_function_def.
4013 (yypstate_delete): New.
4014 (yypush_parse): Change parameters yynval and yynlloc to be const.
4015 * tests/calc.at (_AT_DATA_CALC_Y): Use new yypstate_new and
4016 yypstate_delete functions.
4017
4018 2006-12-13 Joel E. Denny <jdenny@ces.clemson.edu>
4019
4020 * configure.ac (AC_PREREQ): Require Autoconf 2.61 because of our
4021 strange test case titles. Reported by Bob Rossi.
4022
4023 2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
4024
4025 * TODO: Add pointer to Sylvain Schmitz's work on static detection
4026 of potential ambiguities in GLR grammers.
4027
4028 2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
4029
4030 * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
4031 `bison ', use m4_index instead of m4_substr since chopping up a string
4032 containing M4-special characters causes problems here.
4033
4034 Fix a couple of bugs related to special characters in user-specified
4035 file names, and make it easier for skeletons to compute output file
4036 names with the same file name prefix as Bison-computed output file
4037 names.
4038 * data/glr.cc, data/push.c, data/yacc.c: In @output, use
4039 b4_parser_file_name and b4_spec_defines_file instead of
4040 @output_parser_name@ and @output_header_name@, which are now redundant.
4041 * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
4042 b4_parser_file_name, b4_spec_defines_file, and the new
4043 @basename(FILENAME@) instead of @output_parser_name@ and
4044 @output_header_name@, which inappropriately escaped the file names as
4045 C string literals.
4046 * src/files.c (all_but_ext): Remove static qualifier.
4047 (compute_output_file_names): Move `free (all_but_ext)' to...
4048 (output_file_names_free): ... here since all_but_ext is needed later.
4049 * src/files.h (all_but_ext): Extern.
4050 * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
4051 exactly what MUSCLE_INSERT_STRING used to do.
4052 (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
4053 characters are escaped properly.
4054 * src/output.c (prepare): Define muscle file_name_all_but_ext as
4055 all_but_ext.
4056 For pkgdatadir muscle, maintain previous functionality by using
4057 MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
4058 is that b4_pkgdatadir is used inside m4_include in the skeletons, so
4059 digraphs would never be expanded. Hopefully no one has M4-special
4060 characters in his Bison installation path.
4061 * src/scan-skel.l: Don't parse @output_header_name@ and
4062 @output_parser_name@ anymore since they're now redundant.
4063 In @output, use decode_at_digraphs.
4064 Parse a new @basename command that invokes last_component.
4065 (decode_at_digraphs): New.
4066 (BASE_QPUTS): Remove unused.
4067 * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
4068 (Output file name): New tests.
4069
4070 2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
4071
4072 Warn about output files that are generated by the skeletons and that
4073 conflict with other output files.
4074 * data/glr.c: Don't generate the header file here when glr.cc does.
4075 * src/files.c (file_names, file_names_count): New static globals.
4076 (compute_output_file_names): Invoke output_file_name_check for files
4077 not generated by the skeletons and remove existing checks.
4078 (output_file_name_check): New function that warns about conflicting
4079 output file names.
4080 (output_file_names_free): Free file_names.
4081 * src/files.h (output_file_name_check): Declare.
4082 * src/scan-skel.l: Invoke output_file_name_check for files generated by
4083 the skeletons.
4084 * tests/output.at (AT_CHECK_CONFLICTING_OUTPUT): New.
4085 (Conflicting output files): New tests.
4086
4087 2006-12-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4088
4089 * doc/bison.texinfo: Fix a couple of typos.
4090
4091 2006-12-08 Bob Rossi <bob@brasko.net>
4092
4093 * data/push.c: (yypvarsinit, yypvars, struct yypvars, yypushparse):
4094 Rename to...
4095 (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
4096 update all uses.
4097 (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
4098 (yypush_parse): Rename yypvars argument to yyps and remove redundant
4099 local pv.
4100 (yypstate_init, yypush_parse): Declare in Bison-generated header file.
4101 * tests/calc.at (_AT_DATA_CALC_Y): Use newly named functions.
4102
4103 2006-12-07 Bob Rossi <bob@brasko.net>
4104 and Joel Denny <jdenny@ces.clemson.edu>
4105
4106 * data/push.c (yypvarsinit): Change return type from void* to struct
4107 yypvars*. No longer cast to void* on return.
4108 (struct yypvars): Remove yylen since it need not be remembered between
4109 yypushparse invocations.
4110 (yypushparse): Don't copy between yylen and pv->yylen.
4111
4112 2006-12-05 Bob Rossi <bob@brasko.net>
4113
4114 * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
4115 (yypushparse): Add yynchar, yynlval, yynlloc parameters.
4116 (b4_declare_parser_variables): Do not declare yynerrs for push mode.
4117 (struct yypvars): Remove b4_declare_parser_variables.
4118 (yypvarsinit): Remove init code for removed variables.
4119 (global scope): Do not declare b4_declare_parser_variables if
4120 push or pure mode.
4121 (yypushparse): Add b4_declare_parser_variables.
4122 Init new local variables, and remove init code for removed
4123 yypvars variables.
4124 (yyparse): Delete.
4125 * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
4126 and yyparse for other modes.
4127 (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
4128 * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
4129 (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
4130 (AT_PURE_LEX_IF): True if pure or push parser.
4131
4132 2006-12-05 Joel E. Denny <jdenny@ces.clemson.edu>

4152 %name-prefix, and %output.
4153 * src/parse-gram.y (prologue_declaration): Implement.
4154 * tests/calc.at (Simple LALR Calculator, Simple GLR Calculator, Simple
4155 LALR1 C++ Calculator, Simple GLR C++ Calculator): Remove the `=' from
4156 all but one occurrence of %name-prefix.
4157 * tests/headers.at (export YYLTYPE): Remove the `=' from %name-prefix.
4158 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Likewise.

4163 Useless Rules, Reduced Automaton, Underivable Rules, Empty Language):
4164 Remove the `=' from %output.
4165
4166 2006-11-21 Joel E. Denny <jdenny@ces.clemson.edu>
4167
4168 Don't escape $ in test case titles since Autoconf 2.61 now does that
4169 correctly.

4190 Default %printer and %destructor are not for $accept,
4191 Default %printer and %destructor for mid-rule values): Update.
4192 * tests/input.at (Default %printer and %destructor redeclared,
4193 Unused values with default %destructor): Update.
4194
4195 2006-11-17 Joel E. Denny <jdenny@ces.clemson.edu>
4196
4197 Don't let %prec take a nonterminal.
4198 * src/reader.c (grammar_current_rule_prec_set): Make the %prec symbol a
4199 token.
4200 * tests/input.at (%prec takes a token): New test checking that %prec
4201 won't take a nonterminal.
4202
4203 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4204
4205 * tests/testsuite.at (AT_CHECK): Don't miss an exit value of 0 because
4206 it was double-quoted.
4207 * src/Makefile.am (YACC): Use --warnings=all,error so that Bison's own
4208 grammar is maintained with Bison's highest standards.
4209 * src/getargs.c: Fix some typos in Doxygen comments.
4210
4211 2006-11-10 Joel E. Denny <jdenny@ces.clemson.edu>
4212
4213 Fix memory leaks in scanners generated by at least Flex 2.5.9 and
4214 later. Reported by Paul Eggert in
4215 <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
4216 * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
4217 * src/scan-code.l (translate_action): Don't bother invoking
4218 yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
4219 (code_scanner_free): Instead of invoking
4220 yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
4221 which frees more.
4222 * src/scan-gram.l (gram_scanner_free): Likewise.
4223 * src/scan-skel.l (scan_skel): Likewise.
4224
4225 2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
4226
4227 * src/files.c (tr): Change return type to void.
4228 * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
4229 has been called previously for the same key.
4230 (muscle_find): Return storage instead of value so that
4231 --enable-gcc-warnings doesn't produce warnings that the return discards
4232 const. aver that the value and storage are the same since storage
4233 could potentially be NULL when value is not.
4234 * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
4235 same as 0.
4236
4237 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4238
4239 * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
4240 the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
4241 us a slightly cleaner distribution, and also works.
4242 * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent
4243 gnulib changes.
4244
4245 2006-11-08 Joel E. Denny <jdenny@ces.clemson.edu>
4246 and Paul Eggert <eggert@cs.ucla.edu>
4247
4248 Don't let Bison leak memory except when it complains.
4249 * src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
4250 (spec_defines_file, dir_prefix): Now char *, not const char *,
4251 since they are freed.
4252 * src/files.c: Likewise.
4253 (all_but_ext, all_but_tab_ext, src_extension, header_extension):
4254 Likewise.
4255 (tr): Now operates in-place. All uses changed.
4256 (compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
4257 values.
4258 (compute_file_name_parts, compute_output_file_names): Don't store
4259 read-only data in variables that will be freed.
4260 (compute_output_file_names): Free all_but_ext, all_but_tab_ext,
4261 src_extension, and header_extension.
4262 (output_file_names_free): New public function to free
4263 spec_verbose_file, spec_graph_file, spec_defines_file,
4264 parser_file_name, and dir_prefix.
4265 * src/getargs.c (getargs): Don't store read-only data in variables that
4266 will be freed.
4267 * src/main.c (main): Invoke output_file_names_free, code_scanner_free
4268 (which previously existed but was unused), and quotearg_free.
4269 * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
4270 * src/muscle_tab.c: Likewise.
4271 (muscle_entry): Make the value char const *,
4272 and add a new storage member that is char * and can be freed.
4273 (muscle_entry_free): New private function.
4274 (muscle_init): Use it instead of free.
4275 (muscle_insert, muscle_grow): Update and use new storage member.
4276 (muscle_code_grow): Free the string passed to muscle_grow
4277 since it's not needed anymore.
4278 * src/parse-gram.y (%union): Make `chars' member a `char const *', and
4279 add a new `char *code' member.
4280 ("{...}"): Declare semantic type as code.
4281 * src/scan-code.h (translate_rule_action):
4282 (translate_symbol_action, translate_code, translate_action): Return
4283 `char const *' rather than `char *' since external code should not free
4284 these strings.
4285 * src/scan-code.l: Likewise.
4286 * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
4287 which is "{...}" in the parser.
4288 * tests/Makefile.am (maintainer-check-valgrind): Set
4289 VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
4290 Valgrind.
4291 * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
4292 complain.
4293 * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
4294 expecting a non-zero exit status sets --leak-check=summary and
4295 --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
4296 this case, and we don't want to hear about it.
4297
4298 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
4299
4300 * bootstrap (runtime-po/Makevars): Derive from po/Makevars
4301 instead of from the template, to simplify configuration a bit.
4302 * bootstrap.conf (excluded_files): Don't exclude m4/codeset.m4
4303 and m4/wint_t.m4, as they are needed with the latest gnulib.
4304
4305 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4306
4307 Disable unset/unused mid-rule value warnings by default, and recognize
4308 --warnings=midrule-values to enable them. Discussed starting at
4309 <http://lists.gnu.org/archive/html/help-bison/2006-10/msg00030.html>.
4310 * NEWS (2.3a+): Mention.
4311 * src/getargs.c, src/getargs.h (warnings_args, warnings_types, enum
4312 warnings): Add entry for midrule-values subargument.
4313 * src/reader.c (symbol_should_be_used): Don't return true just because
4314 the value is a set/used mid-rule value unless
4315 --warnings=midrule-values was specified.
4316 * tests/input.at (Unused values, Unused values before symbol
4317 declarations): Run tests with and without --warnings=midrule-values.
4318
4319 * src/reader.c (check_and_convert_grammar): Use symbol_list_free rather
4320 than LIST_FREE directly.
4321
4322 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4323
4324 Finish implementing --warnings=error, which should not be implied by
4325 --warnings=all (or by its synonyms -W and --warnings without
4326 subarguments).
4327 * src/complain.c (set_warning_issued): New function to report that
4328 warnings are being treated as errors and to record an error if so.
4329 Invoke...
4330 (warn_at, warn): ... here.
4331 * src/getargs.c (warnings_args, warnings_types): Reorder so that
4332 "error - warnings are errors" does not appear above "all - all of the
4333 above".
4334 (getargs): For -W and --warnings without subarguments, don't let
4335 FLAGS_ARGMATCH set warnings_error in warnings_flag.
4336 * src/getargs.h (enum warnings): Unset warnings_error in warnings_all.
4337
4338 2006-10-31 Joel E. Denny <jdenny@ces.clemson.edu>
4339
4340 * src/getargs.c (flags_argmatch): Don't cause segmentation fault for
4341 empty subargument list. For example: `bison --warnings= parser.y'.
4342
4343 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4344
4345 * data/push.c, data/yacc.c: Make sure there's a newline at the end of
4346 the parser header file so that gcc doesn't warn.
4347
4348 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4349
4350 Split the default %destructor/%printer into two kinds: <*> and <!>.
4351 Discussed starting at
4352 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00060.html>.
4353 * NEWS (2.3a+): Mention.
4354 * doc/bison.texinfo (Freeing Discarded Symbols): Document this and the
4355 previous change today related to mid-rules.
4356 (Table of Symbols): Remove %symbol-default and add <*> and <!>.
4357 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): Remove.
4358 (TYPE_TAG_ANY): Add as <*>.
4359 (TYPE_TAG_NONE): Add as <!>.
4360 (generic_symlist_item): Remove RHS for %symbol-default and add RHS's
4361 for <*> and <!>.
4362 * src/scan-gram.l (PERCENT_SYMBOL_DEFAULT): Remove.
4363 (TYPE_TAG_ANY, TYPE_TAG_NONE): Add.
4364 * src/symlist.c (symbol_list_default_new): Split into tagged and
4365 tagless versions.
4366 (symbol_list_destructor_set, symbol_list_printer_set): Split
4367 SYMLIST_DEFAULT case into SYMLIST_DEFAULT_TAGGED and
4368 SYMLIST_DEFAULT_TAGLESS.
4369 * src/symlist.h: Update symbol_list_default*_new prototypes.
4370 (symbol_list.content_type): Split enum value SYMLIST_DEFAULT into
4371 SYMLIST_DEFAULT_TAGGED and SYMLIST_DEFAULT_TAGLESS.
4372 * src/symtab.c (default_destructor, default_destructor_location,
4373 default_printer, default_printer_location): Split each into tagged and
4374 tagless versions.
4375 (symbol_destructor_get, symbol_destructor_location_get,
4376 symbol_printer_get, symbol_printer_location_get): Implement tagged
4377 default and tagless default cases.
4378 (default_destructor_set, default_printer_set): Split each into tagged
4379 and tagless versions.
4380 * src/symtab.h: Update prototypes.
4381 * tests/actions.at (Default %printer and %destructor): Rename to...
4382 (Default tagless %printer and %destructor): ... this, and extend.
4383 (Per-type %printer and %destructor): Rename to...
4384 (Default tagged and per-type %printer and %destructor): ... this, and
4385 extend.
4386 (Default %printer and %destructor for user-defined end token): Extend.
4387 (Default %printer and %destructor are not for error or $undefined):
4388 Update.
4389 (Default %printer and %destructor are not for $accept): Update.
4390 (Default %printer and %destructor for mid-rule values): Extend.
4391 * tests/input.at (Default %printer and %destructor redeclared): Extend.
4392 (Unused values with default %destructor): Extend.
4393
4394 2006-10-21 Joel E. Denny <jdenny@ces.clemson.edu>
4395
4396 Don't apply the default %destructor/%printer to an unreferenced midrule
4397 value. Mentioned at
4398 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00104.html>.
4399 * src/symtab.c (dummy_symbol_get): Name all dummy symbols initially
4400 like $@n instead of just @n so that the default %destructor/%printer
4401 logic doesn't see them as user-defined symbols.
4402 (symbol_is_dummy): Check for both forms of the name.
4403 * src/reader.c (packgram): Remove the `$' from each midrule symbol
4404 name for which the midrule value is referenced in any action.
4405 * tests/actions.at (Default %printer and %destructor for mid-rule
4406 values): New test.
4407 * tests/regression.at (Rule Line Numbers, Web2c Report): Update output
4408 for change to dummy symbol names.
4409
4410 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
4411
4412 Warn about unset midrule $$ if the corresponding $n is used.
4413 * src/reader.c (symbol_should_be_used): Check midrule parent rule for
4414 $n usage.
4415 (packgram): Before invoking grammar_rule_check on any rule, make sure
4416 all actions have already been scanned in order to set `used' flags.
4417 Otherwise, checking that a midrule's $$ is set will not always work
4418 properly because the midrule check must forward-reference the midrule's
4419 parent rule.
4420 * tests/input.at (AT_CHECK_UNUSED_VALUES): Extend to check the new
4421 warning.
4422
4423 2006-10-20 Joel E. Denny <jdenny@ces.clemson.edu>
4424
4425 More improvements to the documentation of the prologue alternatives:
4426 * NEWS (2.3a+): Mention the new `Prologue Alternatives' section in the
4427 Bison manual.
4428 * doc/bison.texinfo (Prologue Alternatives): Correct some errors. Add
4429 some text to clarify the relative importance of the new directives and
4430 to show how these directives may be viewed as code labels.
4431
4432 2006-10-16 Joel E. Denny <jdenny@ces.clemson.edu>
4433
4434 Similar to the recently removed %before-header, add %code-top as the
4435 alternative to the pre-prologue. Mentioned at
4436 <http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00063.html>.
4437 Also, let the prologue alternatives appear in the grammar section.
4438 * src/parse-gram.y (PERCENT_CODE_TOP): New token.
4439 (prologue_declaration): Move the existing prologue alternatives to...
4440 (grammar_declaration): ... here and add %code-top.
4441 * src/scan-gram.l (PERCENT_CODE_TOP): New token.
4442
4443 Clean up and extend documentation for the prologue alternatives.
4444 * NEWS (2.3a+): Describe prologue alternatives.
4445 * doc/bison.texinfo (Prologue): Move discussion of prologue
4446 alternatives to...
4447 (Prologue Alternatives): ... this new section, and extend it to discuss
4448 all 4 directives in detail.
4449 (Table of Symbols): Clean up discussion of prologue alternatives and
4450 add %code-top.
4451
4452 2006-10-16 Juan Manuel Guerrero <juan.guerrero@gmx.de>
4453
4454 DJGPP specific issues.
4455
4456 * djgpp/config.bat: config.hin has been moved to lib. Adjust
4457 config.bat accordingly.
4458 * djgpp/config.sed: Adjust config.sed for the use of autoconf 2.60.
4459 * djgpp/config.site: Likewise.
4460
4461 2006-10-16 Paolo Bonzini <bonzini@gnu.org>
4462

4464 http://lists.gnu.org/archive/html/bison-patches/2006-10/msg00002.html
4465
4466 * data/bison.m4 (b4_user_requires, b4_user_provides): New.
4467 (b4_user_start_header): Remove.
4468 * data/glr.c: Use new macros instead of b4_*start_header
4469 and b4_*end_header.
4470 * data/glr.cc: Likewise.
4471 * data/lalr1.cc: Likewise.
4472 * data/push.c: Likewise.
4473 * data/yacc.c: Likewise.

4479 * src/scan-gram.l: Likewise.
4480 * tests/actions.at: Likewise.
4481
4482 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

4485 Problem reported by Joel E. Denny.
4486
4487 2006-10-14 Jim Meyering <jim@meyering.net>
4488
4489 (Sync from coreutils.)
4490 Work also when the working directory (with e.g. coreutils sources)
4491 is version controlled with git, rather than CVS.
4492 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
4493 rather than CVS.
4494 In messages and comments, say e.g., "checked-out sources",
4495 rather than "CVS sources".
4496 (version_controlled_file): New function. Work for git as well as
4497 for CVS. Don't use grep's -q option.
4498 (slurp): Call it here, in place of CVS-specific code.
4499
4500 2006-10-14 Joel E. Denny <jdenny@ces.clemson.edu>
4501
4502 Fix testsuite for ./configure --enable-gcc-warnings:
4503 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
4504 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
4505 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
4506 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
4507 * test/regression.at (Diagnostic that expects two alternatives):
4508 Likewise.
4509
4510 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4511
4512 * bootstrap.conf (gnulib_modules): Add config-h.
4513 * djgpp/subpipe.c: Include <config.h> unconditionally; don't
4514 worry about HAVE_CONFIG_H.
4515 * lib/abitset.c: Likewise.
4516 * lib/bitset.c: Likewise.
4517 * lib/bitset_stats.c: Likewise.
4518 * lib/bitsetv-print.c: Likewise.
4519 * lib/bitsetv.c: Likewise.

4522 * lib/lbitset.c: Likewise.
4523 * lib/subpipe.c: Likewise.
4524 * lib/timevar.c: Likewise.
4525 * lib/vbitset.c: Likewise.
4526 * lib/bitset.c: Include "bitset.h" first, to test interface.
4527 * lib/bitset_stats.c: Include "bitset_stats.h" first.
4528 * lib/bitsetv-print.c: Include "bitsetv-print.h" first.
4529 * lib/bitsetv.c: Include "bitsetv.h" first.
4530 * lib/get-errno.c: Include "get-errno.h" first.
4531 * m4/.cvsignore: Add config-h.m4.
4532 * tests/actions.at (Default %printer and %destructor for ...):
4533 Adjust expected line numbers in output to reflect removal of #if
4534 HAVE_CONFIG_H lines.
4535 * tests/glr-regression.at (Missed %merge type warnings when ...):
4536 Likewise.
4537 * tests/regression.at (Braced code in declaration in rules section):
4538 Likewise.
4539 * tests/atlocal.in (CPPFLAGS): Don't define HAVE_CONFIG_H.
4540 * tests/local.at (AT_DATA_GRAMMAR_PROLOGUE):
4541 Include <config.h> unconditionally.
4542
4543 * bootstrap: Sync from coreutils, as follows:
4544
4545 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4546
4547 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
4548 variable was sometimes used without being initialized. This
4549 messed up the installation of the INSTALL file in some cases.
4550
4551 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4552
4553 * bootstrap (usage, main program, symlink_to_gnulib): Add option
4554 --copy. Inspired by a suggestion from Bruno Haible.
4555
4556 2006-10-03 Jim Meyering <jim@meyering.net>
4557
4558 * bootstrap: Undo last change to this file, since now gnulib-tool
4559 sticks with the automake default in generating dependencies.
4560
4561 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
4562
4563 * configure.ac: Use AC_PROG_CC_STDC; this is more modern than
4564 the old AC_PROG_CC / AM_PROG_CC_STDC combination.
4565
4566 * doc/bison.1: Add copyright notice.
4567
4568 * data/glr.c: Don't include <stdarg.h>; not used.
4569
4570 * NEWS: The -g and --graph options now output graphs in Graphviz
4571 DOT format, not VCG format.
4572 * doc/bison.1: Likewise.
4573 * doc/bison.texinfo (Understanding, Bison Options): Likewise.
4574 * THANKS: Add Satya Kiran Popuri, who proposed the initial version
4575 of this change in
4576 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00158.html>.
4577 * TODO: Remove Graphviz entry.
4578 * src/Makefile.am (bison_SOURCES): Add graphviz.c and graphviz.h;
4579 remove vcg.c, vcg.h, vcg_defaults.h.
4580 * src/vcg.c, src/vcg.h, src/vcg_defaults.h: Remove.
4581 * src/graphviz.c, src/graphviz.h: New files.
4582 * src/files.c (compute_output_file_names): Output .dot, not .vcg.
4583 * src/files.h: Make comment more generic.
4584 * src/main.c (main): Likewise.
4585 * src/print_graph.h: Likewise.
4586 * src/getargs.c (usage): Make usage description more generic.
4587 * src/print_graph.c: Include graphviz.h rather than vcg.h.
4588 (static_graph, fgraph): Remove. All uses changed to pass
4589 arguments instead of sharing a static var.
4590 (print_core, print_actions, print_state, print_graph):
4591 Output graphviz format rather than VCG format.
4592 * tests/.cvsignore: Remove *.vcg; add *.dot.
4593 * tests/output.at: Expect *.dot files, not *.vcg files.
4594
4595 * data/Makefile.am (dist_pkgdata_DATA): Add bison.m4; this
4596 accommodates the 2006-10-08 change.

4602 (struct yypvars): Remove yyssa_ptr and yyerror_range_ptr fields.
4603 (yypvarsinit): Remove init of removed fields.

4605
4606 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
4607
4608 * data/push.c (yypushparse): Fix memory leak if yymsg is malloced
4609 in a push parser. Reindent slightly to match yacc.c better.
4610
4611 2006-10-11 Bob Rossi <bob@brasko.net>
4612
4613 * data/push.c (struct yypvars): Remove yymsgbuf, yymsgbuf_ptr, yymsg,
4614 yymsg_alloc fields.
4615 (yypvarsinit, yypushparse): Remove init of removed fields.
4616 (yypushparse): Use yymsgbuf instead of yymsgbuf_ptr.
4617
4618 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
4619
4620 * THANKS: Add Paolo Bonzini and Bob Rossi.
4621
4622 2006-10-08 Paolo Bonzini <bonzini@gnu.org>
4623
4624 * data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
4625 b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
4626 b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
4627 b4_define_user_cde and uses): Remove.
4628 (b4_comment, b4_prefix, b4_sync_start): New.
4629 * data/bison.m4: New file, with most of the content removed from c.m4.
4630 * src/muscle_tab.h: Use "do {...} while(0)" throughout.
4631 * src/output.c (output_skeleton): Pass bison.m4.
4632 (prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
4633 only if specified.
4634
4635 2006-10-05 Paul Eggert <eggert@cs.ucla.edu>
4636
4637 Fix test failure reported by Tom Lane in
4638 <http://lists.gnu.org/archive/html/bug-bison/2006-10/msg00000.html>
4639 and try to make such failures easier to catch in the future.
4640 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
4641 that's now the caller's responsibility.
4642 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
4643 Set yychar = YYEOF if it's negative.
4644 * tests/actions.at (yylex): Abort if asked to read past EOF.
4645 * tests/conflicts.at (yylex): Likewise.
4646 * tests/cxx-type.at (yylex): Likewise.
4647 * tests/glr-regression.at (yylex): Likewise.
4648 * tests/input.at (yylex): Likewise.
4649 * tests/regression.at (yylex): Likewise.
4650 * tests/torture.at (yylex): Likewise.
4651
4652 2006-10-01 Paul Eggert <eggert@cs.ucla.edu>
4653
4654 Fix problems with translating English-language diagnostics.
4655 * bootstrap: Fix bug introduced in recent bootstrap changes, with
4656 respect to bison-runtime pot generation. The YY_ stuff
4657 wasn't being captured.
4658 * bootstrap.conf (XGETTEXT_OPTIONS_RUNTIME): New var.
4659 * po/POTFILES.in: Add src/location.c, src/scan-code.l.
4660 * runtime-po/POTFILES.in: Add data/push.c.
4661
4662 2006-09-29 Paul Eggert <eggert@cs.ucla.edu>
4663
4664 Merge bootstrap changes from coreutils.
4665
4666 2006-09-28 Jim Meyering <jim@meyering.net>
4667
4668 Automatically generated dependencies are important even
4669 when all of the sources in a directory come from gnulib.
4670 * bootstrap (gnulib_tool): Remove the "no-dependencies" automake
4671 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
4672
4673 2006-09-23 Jim Meyering <jim@meyering.net>
4674
4675 * bootstrap (gnulib_tool_options): Add "--local-dir gl".
4676
4677 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4678
4679 * bootstrap: Add support for --force.
4680 (usage): New function. Describe usage less tersely.
4681 (CVS_only_file): New var.
4682
4683 2006-09-21 Paul Eggert <eggert@cs.ucla.edu>
4684
4685 * data/push.c (YYPUSH_MORE): Make it an enum instead.
4686 (yypushparse): Use YYPUSH_MORE instead of the mystery constant.
4687 Adjust white space and comments to match GNU style better.
4688
4689 2006-09-20 Bob Rossi <bob@brasko.net>
4690
4691 * data/push.c (yyresult_get): Remove function.
4692 (YYPUSH_MORE): Add #define.
4693 (yypushparse): Modify return value.
4694
4695 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4696
4697 * stamp-h.in: Remove; no longer needed.
4698 * .cvsignore: Replace autom4te.cache and config.cache with *.cache.
4699 Remove config.h, config.hin, intl (no longer created).
4700 * lib/.cvsignore: Add config.h, config.hin, configmake.h, inttypes.h,
4701 stamp-h1.
4702
4703 Sync bootstrap from coreutils, as follows:
4704
4705 2006-09-18 Paul Eggert <eggert@cs.ucla.edu>
4706
4707 * bootstrap (symlink_to_gnulib): New function.
4708 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
4709 to copies-of-gnulib.
4710 (cp_mark_as_generated, slurp, gnulib_files):
4711 Avoid making a copy if it's the same as the old version.
4712 (gnulib_files): Add support for this variable (used by Bison).
4713
4714 2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
4715
4716 * src/getargs.c (usage): Rework to use conventions similar to
4717 coreutils, to make translation a bit easier and the code a bit
4718 smaller. Problem reported by Tim Van Holder.
4719
4720 2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
4721
4722 Use some of gnulib's new modules, taken from coreutils.
4723
4724 * bootstrap: Sync from coreutils, except add support for gnulib_files.
4725 * bootstrap.conf: New file.
4726 (gnulib_modules): Add configmake, inttypes, unistd.
4727 (XGETTEXT_OPTIONS): Add complain, complain_at,
4728 fatal, fatal_at, warn, warn_at, unexpected_end.
4729 * configure.ac (AC_CONFIG_HEADERS): config.h is now in lib, not here.
4730 (gl_USE_SYSTEM_EXTENSIONS): Remove; gl_EARLY now does this.
4731 (gl_EARLY): Add.
4732 (AM_STDBOOL_H): Remove; gl_INIT now dows this.
4733 (gl_INIT): Add
4734 (GNULIB_AUTOCONF_SNIPPET): Remove.
4735 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
4736 the pickiest.
4737 * lib/.cvsignore: Add inttypes_.h.
4738 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
4739 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
4740 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
4741 no-longer-necessary initializations.
4742 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
4743 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
4744 use the unistd module.
4745 * src/system.h: Likewise.
4746 * m4/.cvsignore: Remove *_gl.m4, gnulib.m4, inttypes_h.m4, uintmax_t.m4,
4747 ulonglong.m4. Add gettext.m4, gnulib-cache.m4, gnulib-comp.m4,
4748 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
4749 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
4750 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
4751 * src/system.h: Include inttypes.h unconditionally, now that we
4752 use the inttypes module. Don't bother to include stdint.h, since
4753 inttypes.h now does that for us.
4754 (LOCALEDIR): Remove, now that we use the configmake module.
4755 * src/getargs.c: Include configmake.h.
4756 * src/main.c: Likewise.
4757 * src/output.c: Likewise.
4758 * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
4759 not from $abs_top_builddir, since config.h moved.
4760
4761
4762 Port to GCC 2.95. First two problems reported by Michael Deutschmann in
4763 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
4764
4765 * src/parse-gram.y (symbol_declaration): Don't put statements
4766 before declarations; it's not portable to C89.
4767 * src/scan-code.l (handle_action_at): Likewise.
4768
4769 * src/scan-code.l: Always initialize braces_level; the old code
4770 left it uninitialized and therefore had undefined behavior.
4771
4772 Don't attempt to redefine 'assert', since it runs afoul of
4773 systems where standard headers (mistakenly) include <assert.h>.
4774 Instead, define and use our own alternative, called 'aver'.
4775 * src/reader.c: Don't include assert.h, since we no longer
4776 use assert.
4777 * src/scan-code.l: Likewise.
4778 * src/system.h (assert): Remove, replacing with....
4779 (aver): New function, taking a bool arg. All uses changed.
4780 * src/tables.c (pack_vector): Ensure that aver arg is bool,
4781 not merely an integer.
4782
4783 2006-09-15 Bob Rossi <bob@brasko.net>
4784
4785 * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
4786 * data/c.m4 (YYPUSH): New.
4787 (b4_push_if): New macro. Use it instead of #ifdef YYPUSH.
4788 * src/getargs.c (push_parser): New var.
4789 * src/getargs.h (push_parser): New declaration.
4790 * src/output.c (prepare): Add macro insertion of `push_flag'.
4791 * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
4792 (prologue_declaration): Parse %push-parser.
4793 * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
4794 * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
4795 list of removed lines from the traces observed.
4796 (AT_CHECK_CALC_LALR): Added push parser tests.
4797
4798 2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
4799
4800 * NEWS: Version 2.3a.
4801 * configure.ac (AC_INIT): Likewise.
4802
4803 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
4804 "#define YYSTYPE int" that caused "make maintainer-check" to fail
4805 due to header ordering dependencies. I don't know why the #define
4806 was there.
4807
4808 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
4809 runtime cost when YYDEBUG is not defined, and so that some tests
4810 that used to fail now work. Problem and initial suggestion by
4811 Paolo Bonzini.
4812 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
4813 * data/glr.cc (b4_parser_class_name):
4814 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
4815 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
4816 (yydebug_) [YYDEBUG]: New member.
4817 (yycdebug_): Now defined only if YYDEBUG.
4818 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
4819 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
4820 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
4821 if YYYDEBUG.
4822 (debug_stream, set_debug_stream, debug_level, set_debug_level):
4823 Define only if YYDEBUG.
4824 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
4825 set_debug_level.
4826 * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
4827 * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
4828 AT_CHECK_CALC_GLR_CC that are working now.
4829
4830 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
4831
4832 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
4833 We don't need them in glr.cc, and glr.c defines them.
4834 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
4835 assumes that defining it to anything is the same as defining
4836 it to 1. Problem reported by Paolo Bonzini.
4837
4838 2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
4839
4840 * data/c.m4 (b4_null, b4_case): Define.
4841 * src/output.c (prepare_symbols): Use b4_null.
4842 (user_actions_output): Use b4_case.
4843
4844 2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
4845
4846 * data/glr.c (b4_shared_declarations): Put start-header first,
4847 before any #includes that we generate, so that feature-test
4848 macros work. Problem reported by Michael Deutschmann in
4849 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
4850 * data/lalr1.cc: Likewise.
4851 * doc/bison.texinfo (Prologue): Document that feature-test macros
4852 should be defined before any Bison declarations.
4853 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
4854 that depend on location.hh after, not before, Bison decls, since
4855 we now include location.hh after the first user prologue.
4856
4857 * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
4858 Sander Brandenburg in
4859 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
4860 Also, fix minor white space and comment issues.
4861 (Prologue): Mention that it's better to define feature-test macros
4862 before Bison declarations. Problem reported by Michael Deutschmann.
4863
4864 * README-cvs: Fix typo: "&" should be "&&". Problem reported
4865 by Jim Meyering.
4866 * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
4867 This adjusts to recent gnulib changes.
4868
4869 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4870
4871 Finish implementation of per-type %destructor/%printer. Discussed
4872 starting at
4873 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
4874 and
4875 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
4876 * NEWS (2.3+): Add a description of this feature to the default
4877 %destructor/%printer description.
4878 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
4879 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
4880 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
4881 list node contains a semantic type.
4882 * src/symtab.c, src/symtab.h: Extend with a table that associates
4883 semantic types with their %destructor's and %printer's.
4884 (semantic_type_from_uniqstr, semantic_type_get,
4885 semantic_type_destructor_set, semantic_type_printer_set): New functions
4886 composing the public interface of that table.
4887 (symbol_destructor_get, symbol_destructor_location_get,
4888 symbol_printer_get, symbol_printer_location_get): If there's no
4889 per-symbol %destructor/%printer, look up the per-type before trying
4890 the default.
4891 * tests/actions.at (Per-type %printer and %destructor): New test case.
4892 * tests/input.at (Default %printer and %destructor redeclared):
4893 Extend to check that multiple occurrences of %symbol-default in a
4894 single %destructor/%printer declaration is an error.
4895 (Per-type %printer and %destructor redeclared, Unused values with
4896 per-type %destructor): New test cases.
4897
4898 2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
4899
4900 Require default %destructor/%printer to be declared using
4901 %symbol-default instead of an empty symbol list, and start working on
4902 new per-type %destructor/%printer. Discussed at
4903 <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
4904 * NEWS (2.3+): Add %symbol-default to example.
4905 * bison.texinfo (Freeing Discarded Symbols): Likewise.
4906 (Table of Symbols): Add entry for %symbol-default.
4907 * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
4908 (generic_symlist, generic_symlist_item): New nonterminals for creating
4909 a list in which each item is a symbol, semantic type, or
4910 %symbol-default.
4911 (grammar_declaration): Use generic_symlist in %destructor and %printer
4912 declarations instead of symbols.1 or an empty list.
4913 (symbol_declaration, precedence_declaration, symbols.1): Update actions
4914 for changes to symbol_list.
4915 * src/reader.c: Update for changes to symbol_list.
4916 * src/scan-code.l: Likewise.
4917 * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
4918 * src/symlist.c, src/symlist.h: Extend such that a list node may
4919 represent a semantic type or a %symbol-default in addition to just an
4920 ordinary symbol. Add switched functions for setting %destructor's and
4921 %printer's.
4922 * tests/actions.at, tests/input.at: Add %symbol-default to all default
4923 %destructor/%printer declarations.
4924
4925 2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
4926
4927 Whether the default %destructor/%printer applies to a particular symbol
4928 isn't a question of whether the user *declares* that symbol (in %token,
4929 for example). It's a question of whether the user by any means
4930 *defines* the symbol at all (by simply using a char token, for
4931 example). $end is defined by Bison whereas any other token with token
4932 number 0 is defined by the user. The error token is always defined by
4933 Bison regardless of whether the user declares it with %token, but we
4934 may one day let the user define error as a nonterminal instead.
4935 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
4936 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
4937 the meaning of "user-defined".
4938 * tests/actions.at (Default %printer and %destructor for user-declared
4939 end token): Rename to...
4940 (Default %printer and %destructor for user-defined end token): ...
4941 this.
4942
4943 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
4944 computation of whether to apply the default, don't maintain a list of
4945 every Bison-defined symbol. Instead, just check for a first character
4946 of '$', which a user symbol cannot have, and check for the error token.
4947
4948 2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
4949
4950 Don't apply the default %destructor or %printer to the error token,
4951 $undefined, or $accept. This change fits the general rule that the
4952 default %destructor and %printer are only for user-declared symbols,
4953 and it solves several difficulties that are described in the new test
4954 cases listed below.
4955 * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
4956 * tests/actions.at (Default %printer and %destructor are not for error
4957 or $undefined, Default %printer and %destructor are not for $accept):
4958 New test cases.
4959
4960 2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
4961
4962 Allow %start after the first rule.
4963 * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
4964 when parsing the first rule.
4965 (check_and_convert_grammar): Search for it here after all grammar
4966 declarations have been parsed. Skip midrules, which have dummy LHS
4967 nonterminals.
4968 * src/symtab.c (symbol_is_dummy): New function.
4969 * src/symtab.h (symbol_is_dummy): Declare it.
4970 * tests/input.at (%start after first rule): New test.
4971
4972 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4973
4974 Redo some of the previous commit: add back the ability to use
4975 non-aliased/undeclared string literals since it might be useful to
4976 those declaring %token-table.
4977 * src/reader.c (check_and_convert_grammar): Undo changes in previous
4978 commit: don't worry about complaints from symbols_pack.
4979 * src/symtab.c (symbol_new, symbol_class_set,
4980 symbol_check_alias_consistency): Undo changes in previous commit: count
4981 each string literal as a new symbol and token, assign it a symbol
4982 number, and don't complain about non-aliased string literals.
4983 (symbols_pack): Since symbol_make_alias still does not decrement symbol
4984 and token counts but does still set aliased tokens to the same number,
4985 symbol_pack_processor now leaves empty slots in the symbols array.
4986 Remove those slots.
4987 * tests/regression.at (Undeclared string literal): Remove test case
4988 added in previous commit since non-aliased string literals are allowed
4989 again.
4990 (Characters Escapes, Web2c Actions): Undo changes in previous commit:
4991 remove unnecessary string literal declarations.
4992 * tests/sets.at (Firsts): Likewise.
4993
4994 2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
4995
4996 Don't allow an undeclared string literal, but allow a string literal to
4997 be used before its declaration.
4998 * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
4999 symbols_pack complained.
5000 * src/symtab.c (symbol_new): Don't count a string literal as a new
5001 symbol.
5002 (symbol_class_set): Don't count a string literal as a new token, and
5003 don't assign it a symbol number since symbol_make_alias does that.
5004 (symbol_make_alias): It's not necessary to decrement the symbol and
5005 token counts anymore. Don't assume that an alias declaration occurs
5006 before any uses of the identifier or string, and thus don't assert that
5007 one of them has the highest symbol number so far.
5008 (symbol_check_alias_consistency): Complain if there's a string literal
5009 that wasn't declared as an alias.
5010 (symbols_pack): Bail if symbol_check_alias_consistency failed since
5011 symbol_pack asserts that every token has been assigned a symbol number
5012 although undeclared string literals have not.
5013 * tests/regression.at (String alias declared after use, Undeclared
5014 string literal): New test cases.
5015 (Characters Escapes, Web2c Actions): Declare string literals as
5016 aliases.
5017 * tests/sets.at (Firsts): Likewise.
5018
5019 2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
5020
5021 In the grammar scanner, STRING_FINISH unclosed constructs and return
5022 them to the parser in order to improve error messages.
5023 * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
5024 SC_BRACED_CODE, SC_PROLOGUE): Implement.
5025 * tests/input.at (Unclosed constructs): New test case.
5026 * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
5027 seen.
5028
5029 * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
5030 unused global.
5031
5032 2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
5033
5034 Handle string aliases for character tokens correctly.
5035 * src/symtab.c (symbol_user_token_number_set): If the token has an
5036 alias, check and set its alias's user token number instead of its own,
5037 which is set to indicate the alias. Previously, every occurrence of
5038 the character token in the grammar overwrote that alias indicator with
5039 the character code.
5040 * tests/input.at (String aliases for character tokens): New test.
5041
5042 2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
5043
5044 * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
5045
5046 2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
5047
5048 * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
5049 to prevent failures when building on older platforms.
5050 Check for autopoint failure.
5051 Set XGETTEXT_OPTIONS to values that check for C format strings,
5052 so that translators are warned about them (this also helps
5053 prevent core dumps).
5054
5055 * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
5056 function, since it simplifies our code a bit.
5057
5058 * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
5059 rather than -W, so we don't get bogus warnings about sign comparisons.
5060 Add -Wpointer-arith, since that warning is useful (it reports code
5061 that does not conform to C89 and that some compilers reject).
5062 * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
5063 since it's no longer needed.
5064
5065 2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
5066
5067 Clean up scanners a bit.
5068 * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
5069 definitions so gcc won't warn when obstack_for_string is unused.
5070 * src/scan-code.l: config.h and system.h are already #include'd by
5071 scan-code-c.c, so get rid of them here.
5072 * src/scan-gram.l: Likewise.
5073 * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
5074 definitions rather than duplicating the rest of it.
5075 * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
5076
5077 2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
5078
5079 Suppress signed/unsigned comparison warnings for yycheck.
5080 * data/c.m4 (b4_safest_int_type): New macro.
5081 * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
5082 a signed int type, cast it to b4_safest_int_type first.
5083 * data/yacc.c: Likewise.
5084 (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
5085 also overwritten.
5086
5087 2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
5088
5089 * doc/bison.texinfo: Fix some typos.
5090
5091 2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
5092
5093 * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
5094 po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
5095
5096 * bootstrap (gnulib_tool): Stop using --assume-autoconf;
5097 the latest gnulib does this a different way.
5098 (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
5099 translation was patched, so stop omitting it.
5100
5101 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5102
5103 Enable declaration of default %printer/%destructor. Make the parser
5104 use these for all user-declared grammar symbols for which the user does
5105 not declare a specific %printer/%destructor. Thus, the parser uses it
5106 for token 0 if the user declares it but not if Bison generates it as
5107 $end. Discussed starting at
5108 <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
5109 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
5110 and
5111 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
5112 * NEWS (2.3+): Mention.
5113 * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
5114 declare a %destructor for a mid-rule's semantic value. It's just
5115 impossible to declare one specific to it.
5116 (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
5117 code. Describe default %destructor form.
5118 * src/parse-gram.y (grammar_declaration): Parse default
5119 %printer/%destructor declarations.
5120 * src/output.c (symbol_destructors_output): Use symbol_destructor_get
5121 and symbol_destructor_location_get rather than accessing the destructor
5122 and destructor_location members of struct symbol.
5123 (symbol_printers_output): Likewise but for %printer's.
5124 * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
5125 again.
5126 * src/symtab.c (default_destructor, default_destructor_location,
5127 default_printer, default_printer_location): New static global
5128 variables to record the default %destructor and %printer.
5129 (symbol_destructor_get, symbol_destructor_location_get,
5130 symbol_printer_get, symbol_printer_location_get): New functions to
5131 compute the appropriate %destructor and %printer for a symbol.
5132 (default_destructor_set, default_printer_set): New functions to set the
5133 default %destructor and %printer.
5134 * src/symtab.h: Prototype all those new functions.
5135 * tests/actions.at (Default %printer and %destructor): New test to
5136 check that the right %printer and %destructor are called, that they're
5137 not called for $end, and that $$ and @$ work correctly.
5138 (Default %printer and %destructor for user-declared end token): New
5139 test to check that the default %printer and %destructor are called for
5140 a user-declared end token.
5141 * tests/input.at (Default %printer and %destructor redeclared, Unused
5142 values with default %destructor): New tests to check related grammar
5143 warnings and errors.
5144
5145 2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
5146
5147 Clean up handling of %destructor for the end token (token 0).
5148 Discussed starting at
5149 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
5150 and
5151 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
5152
5153 Make the skeletons consistent in how they pop the end token and invoke
5154 its %destructor.
5155 * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
5156 state, which has token number 0, since this would invoke the
5157 %destructor for the end token.
5158 * data/lalr1.cc (yy::parser::parse): Don't check for the final state
5159 until after shifting the end token, or else it won't be popped.
5160 * data/yacc.c (yyparse): Likewise.
5161
5162 * data/glr.c (yyparse): Clear the lookahead after shifting it even when
5163 it's the end token. Upon termination, destroy an unshifted lookahead
5164 even when it's the end token.
5165 * data/lalr1.cc (yy::parser::parse): Likewise.
5166 * data/yacc.c (yyparse): Likewise.
5167
5168 * src/reader.c (packgram): Don't check rule 0. This suppresses unused
5169 value warnings for the end token when the user gives the end token a
5170 %destructor.
5171
5172 * tests/actions.at (Printers and Destructors): Test all the above.
5173
5174 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
5175
5176 Update to latest gnulib and gettext versions.
5177 * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
5178 Add fopen-safer.
5179 (gnulib_files): Add m4/warning.m4. Don't worry about files
5180 overwritten by autopoint.
5181 Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
5182 Suppress "id", "ms", "tr" translations for now, since gettext 0.15
5183 rejects them.
5184 Don't use autoreconf; instead, invoke autopoint etc. by hand,
5185 so that we can remove the intl files at a better time.
5186 (intl_files_to_remove): Remove aclocal.m4, since it gets
5187 rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
5188 m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
5189 m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
5190 Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
5191 Remove datarootdir hack; no longer needed.
5192 * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
5193 (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
5194 * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
5195 strdup.h.
5196 * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
5197 * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
5198
5199 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
5200
5201 * bootstrap: Adjust to today's change to gnulib-tool by invoking
5202 it with --assume-autoconf='latest-stable'.
5203
5204 2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
5205
5206 * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
5207 least 1.4.7 and 1.4.4) by putting a #line between `typedef union
5208 YYSTYPE' and `{'.
5209 * src/muscle_tab.h (muscle_grow): Replace the header comments with
5210 those from muscle_tab.c since the old ones are misleading.
5211
5212 2006-07-13 Akim Demaille <akim@epita.fr>
5213
5214 Support %define "KEY" {VALUE}.
5215 * src/scan-code.h, src/scan-code.l (translate_action)
5216 (translate_rule_action, translate_symbol_action, translate_code):
5217 Return char *, not const char *.
5218 * src/parse-gram.y (declaration): Rename as...
5219 (prologue_declaration): this.
5220 (string_content): Remove this nonterminal, use STRING.
5221 (braceless, content, content.opt): New nonterminal.
5222 Use them.
5223 (%define): Now accept content.opt, i.e., accept also BRACED_CODE
5224 as value.
5225 * src/scan-gram.l (getargs.h): Don't include it.
5226
5227 2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
5228
5229 * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
5230 rather than a for-loop that declares a local bool variable. This
5231 should work around a compatibility problem with a Cray x1e C++
5232 compiler reported by Hung Nguyen in
5233 <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
5234 The for-loop was introduced in the 2004-11-17 change but I don't
5235 know why it was needed.
5236
5237 2006-07-12 Akim Demaille <akim@epita.fr>
5238
5239 * data/c.m4: Comment changes.
5240
5241 2006-07-10 Akim Demaille <akim@lrde.epita.fr>
5242
5243 * src/complain.c (error_message, ERROR_MESSAGE): New.
5244 To factor...
5245 (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
5246 * src/complain.h, src/complain.c (warning_issued): Remove, unused.
5247
5248 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5249
5250 * NEWS: Instead of %union, you can define and use your own union type
5251 YYSTYPE if your grammar contains at least one <type> tag.
5252 Your YYSTYPE need not be a macro; it can be a typedef.
5253 * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
5254 (Union Decl, Decl Summary): Document this.
5255 * data/glr.c (YYSTYPE): Implement this.
5256 * data/glr.cc (YYSTYPE): Likewise.
5257 * data/lalr1.cc (YYSTYPE): Likewise.
5258 * data/yacc.c (YYSTYPE): Likewise.
5259 * src/output.c (prepare): Output tag_seen_flag.
5260 * src/parse-gram.y (declaration, grammar_declaration):
5261 Use 'union_seen' rather than 'typed' to determine whether
5262 %union has been seen, since grammars can now be typed without
5263 %union.
5264 (symbol_declaration, type.opt, symbol_def):
5265 Keep track of whether a tag has been seen.
5266 * src/reader.c (union_seen, tag_seen): New vars.
5267 (typed): remove.
5268 * src/reader.h (union_seen, tag_seen, typed): Likewise.
5269 * src/scan-code.l (untyped_var_seen): New variable.
5270 (handle_action_dollar): Adjust to above changes.
5271 (handle_action_dollar, handle_action_at):
5272 Improve overflow checking for outlandish numbers.
5273 * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
5274 avoid new diagnostics generated by above changes.
5275 * tests/regression.at (YYSTYPE typedef): Add test to check
5276 for type tags without %union.
5277
5278 * src/symlist.c (symbol_list_length): Return int, not unsigned
5279 int, since callers expect int. This may need to get revisited
5280 once we have proper integer overflow checking.
5281
5282 * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
5283 object is now static.
5284
5285 * src/getargs.c (flags_argmatch): Return void, not int,
5286 to pacify ./configure --enable-gcc-warnings.
5287
5288 * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
5289 since last_string is already defined to FLEX_PREFIX (last_string).
5290
5291 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5292
5293 Implement --warnings/-W.
5294 * src/getargs.c (report_argmatch, trace_argmatch): Remove,
5295 replaced by...
5296 (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
5297 Adjust callers.
5298 * src/getargs.h, src/getargs.c (warnings, warnings_flags)
5299 (warnings_args, warnings_types): New.
5300 (getargs, short_options, long_options): Accept -W/--warnings.
5301 Sort the options by alphabetical order, upper case letter right
5302 before its lower case.
5303
5304 2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
5305
5306 Change %merge result type clash warnings to errors. Discussed at
5307 <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
5308 * src/reader.c (record_merge_function_type): Use complain_at.
5309 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5310 declared later): Update test case results.
5311
5312 2006-07-09 Akim Demaille <akim@lrde.epita.fr>
5313
5314 * src/getargs.h, src/getargs.c: Swap --report and --trace handling
5315 to be in alphabetical order.
5316 (trace_args): Spelling fixes.
5317
5318 2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
5319
5320 * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
5321 so they don't collide with user-defined macros.
5322 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
5323 this was never guaranteed, and now that we're using gnulib stdint,
5324 which defines int_fast16_t to long int, the problem is exposed.
5325
5326 2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
5327
5328 * data/c.m4 (b4_basename): Simplify a bit, since we don't
5329 need the full POSIX semantics (and weren't implementing them
5330 anyway).
5331
5332 Adjust to Autoconf 2.60 and today's gnulib.
5333 * bootstrap (gnulib_modules): Add stdint.
5334 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
5335 no longer copies it.
5336 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
5337 since stdint needs the former and wcwidth (which is now required
5338 by mbswidth) needs the latter.
5339 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
5340 work around a compatibility glitch between gettext 0.14.6 and
5341 Autoconf 2.60.
5342 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
5343 Do not check for uintptr_t, since new stdint module does the right
5344 thing.
5345 * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
5346 Add stdint.h, stdint_.h, wcwidth.h.
5347 * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
5348 Add absolute-header.m4, double-slash-root.m4, longlong.m4,
5349 stdint.m4, wchar_t.m4, wcwidth.m4.
5350 * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
5351 usual order for ../lib/*.h files.
5352 (file_name_split): Use last_component, not base_name, to adjust
5353 to gnulib changes.
5354 * src/parse-gram.h: Include <strverscmp.h> in the usual order
5355 for ../lib/*.h files.
5356 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
5357 Define unconditionally, since we now assume the stdint module.
5358 * src/scan-skel.l: Include <dirname.h>.
5359 (BASE_QPUTS): Use last_component, not base_name.
5360 * src/system.h: Include <unlocked-io.h> in the usual order
5361 for ../lib/*.h files. Include <stdint.h> unconditionally,
5362 since we now use the stdint module.
5363 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
5364 HAVE_UINTPTR_T, since we now use the stdint module.
5365 (base_name): Remove decl, since files now include <dirname.h>
5366 to get the decl.
5367
5368 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5369
5370 * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
5371 New, default to 1.
5372 * data/yacc.c, data/glr.c, data/location.cc: Use them.
5373 * NEWS, doc/bison.texinfo: The initial column and line are 1 by
5374 default.
5375 * tests/calc.at: Adjust.
5376
5377 2006-07-08 Akim Demaille <akim@lrde.epita.fr>
5378
5379 * data/c.m4 (b4_basename): New.
5380 (b4_syncline): Also output the location of its invocation (from
5381 the skeleton).
5382 (b4_user_action, b4_define_user_action, b4_user_actions)
5383 (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
5384 (b4_user_stype): New.
5385 * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
5386
5387 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5388
5389 In the grammar file, the first column is 1 not 0 on the first line as
5390 on every other line.
5391 * src/parse-gram.y (%initial-action): Initialize @$ correctly.
5392 * tests/input.at (Torturing the Scanner): Update output.
5393
5394 * src/scan-gram.l (scanner_cursor): Declare it static.
5395
5396 2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
5397
5398 In warnings, say "previous declaration" rather than "first
5399 declaration".
5400 * src/symtab.c (redeclaration): Do that here.
5401 * src/reader.c (record_merge_function_type): In the case of a result
5402 type clash, report the previous declaration rather than the very first
5403 one in the grammar file.
5404 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5405 declared later): Add a third declaration to check this behavior.
5406 * tests/input.at (Incompatible Aliases): Update output.
5407
5408 2006-06-27 Akim Demaille <akim@epita.fr>
5409
5410 * doc/Doxyfile.in: New.
5411 * doc/Makefile.am: Use it.
5412 * src/lalr.h, src/symtab.h: Initial doxygenation.
5413
5414 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5415
5416 Don't miss %merge result type warnings just because the LHS types are
5417 declared after the %merge. This continues the effort of the previous
5418 patch.
5419 * src/reader.c (get_merge_function): Don't set the merger type yet.
5420 (record_merge_function_type): New function for setting the merger type
5421 and checking for clashes.
5422 (grammar_current_rule_merge_set): Set the location of the %merge for
5423 the current rule.
5424 (packgram): Invoke record_merge_function_type for each rule now that
5425 all symbol type declarations have been parsed.
5426 * src/reader.h (merger_list.type_declaration_location): New member
5427 storing the location of the first %merge from which the type for this
5428 merging function was derived.
5429 * src/symlist.h (symbol_list.merger_declaration_location): New member
5430 storing the location of a rule's %merge, if any.
5431 * tests/glr-regression.at (Missed %merge type warnings when LHS type is
5432 declared later): New test to catch the error fixed by the above patch.
5433
5434 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5435
5436 Get action warnings (grammar_rule_check) right even when symbol
5437 declarations appear after the rules. Discussed at
5438 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
5439 and
5440 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
5441 Don't mistake the type of $$ in a midrule to be that of its parent
5442 rule's $$.
5443 * src/reader.c (grammar_current_rule_end): Don't invoke
5444 grammar_rule_check yet since not all symbol declarations may have been
5445 parsed yet.
5446 (grammar_midrule_action): Likewise.
5447 Don't record whether the midrule's $$ has been used yet since actions
5448 haven't been translated yet.
5449 Record the midrule's parent rule and its RHS index within the parent
5450 rule.
5451 (grammar_current_rule_action_append): Don't translate the action yet
5452 since not all symbol declarations may have been parsed yet and, thus,
5453 warnings about types for $$, $n, @$, and @n can't be reported yet.
5454 (packgram): Translate the action and invoke grammar_rule_check now that
5455 all symbol declarations have been parsed.
5456 * src/scan-code.l (handle_action_dollar): Now that this is invoked
5457 after parsing the entire grammar file, the symbol list here in the case
5458 of a midrule is actually the midrule's empty RHS, so reference its
5459 parent rule's RHS where necessary.
5460 On the other hand, now that you can already know it's a midrule, you
5461 aren't forced to think $$ has the same type as its parent rule's $$.
5462 (handle_action_at): In the case of a midrule, reference the parent rule
5463 where necessary.
5464 * src/symlist.c (symbol_list_new): Initialize new midrule-related
5465 members.
5466 (symbol_list_length): Now that this is invoked after all rules have
5467 been parsed, a NULL symbol (rather than a NULL symbol list node)
5468 terminates a rule. symbol_list_print already does this correctly.
5469 * src/symlist.h (symbol_list.midrule_parent_rule,
5470 symbol_list.midrule_parent_rhs_index): New members so that midrules can
5471 remember their relationships with their parents.
5472 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
5473 fixed by the above patch.
5474 (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
5475 implementing...
5476 (Unused values): ... this old test case and...
5477 (Unused values before symbol declarations): ... this new test case.
5478 This one is the same as `Unused values' except that all symbol
5479 declarations appear after the rules in order to catch the rest of the
5480 errors fixed by the above patch.
5481
5482 2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
5483
5484 More cleanup.
5485 * src/reader.c (current_rule): Declare it static since it's no longer
5486 used outside this file.
5487 (grammar_current_rule_action_append): Remove redundant arguments from
5488 translate_rule_action invocation.
5489 * src/reader.h (current_rule): Remove this unused extern.
5490 * src/scan-code.h (translate_rule_action): Remove redundant arguments.
5491 * src/scan-code.l (translate_rule_action): Likewise.
5492
5493 2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
5494
5495 Clean up yesterday's patch.
5496 * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
5497 to...
5498 * src/reader.c (grammar_current_rule_action_append): ... here for
5499 consistency with grammar_current_rule_symbol_append.
5500 * tests/regression.at (Braced code in declaration in rules section):
5501 Make yyerror and yylex static as usual.
5502
5503 2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
5504
5505 Fix bug that mistakes braced code in a declaration in the rules section
5506 to be a rule action. Mentioned at
5507 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
5508 * src/scan-gram.l: Move midrule action detection from the start of the
5509 scanning of any braced code to...
5510 * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
5511 action. For readability, use $2 and @2 rather than the equivalent
5512 global variables.
5513 * tests/regression.at (Braced code in declaration in rules section):
5514 New test to catch the error fixed by the above patch.
5515
5516 Work on code readability some.
5517 * src/scan-code.l (current_rule): Get rid of this misleading and
5518 redundant declaration: it's actually extern'ed in reader.h.
5519 (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
5520 translate_action): Add a rule argument and use it instead of the global
5521 current_rule.
5522 (translate_rule_action): This already receives current_rule through an
5523 argument, so pass it on to translate_action instead of assigning
5524 current_rule to current_rule.
5525 (translate_symbol_action, translate_code): Pass rule = NULL to
5526 translate_action.
5527
5528 2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
5529
5530 Rename %before-definitions to %start-header and %after-definitions to
5531 %end-header. Don't use these declarations to separate pre-prologue
5532 blocks from post-prologue blocks. Add new order-independent
5533 declarations %before-header and %after-header as alternatives to the
5534 traditional Yacc pre-prologue and post-prologue blocks. Discussed at
5535 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
5536 * NEWS (2.3+): Update for these changes.
5537 * data/glr.c (b4_before_definitions): Update to...
5538 (b4_start_header): ... this.
5539 (b4_after_definitions): Update to...
5540 (b4_end_header): ... this.
5541 * data/glr.cc: Likewise.
5542 * data/lalr1.cc: Likewise.
5543 * data/yacc.c: Likewise.
5544 * doc/bison.texinfo (The prologue): Update names, and replace remaining
5545 prologue blocks with %*-header declarations.
5546 (Calc++ Parser): Likewise.
5547 (Decl Summary): Update names.
5548 (Table of Symbols): Update description.
5549 * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...
5550 (PERCENT_END_HEADER): ... this.
5551 (PERCENT_BEFORE_DEFINITIONS): Update to...
5552 (PERCENT_START_HEADER): ... this.
5553 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5554 (declaration): Update token names and m4 macro names.
5555 When parsing %end-header and %start-header, invoke translate_code
5556 before muscle_code_grow, and no longer set global booleans to remember
5557 whether these declarations have been seen.
5558 Parse new %after-header and %before-header.
5559 * src/reader.c (before_definitions, after_definitions): Remove.
5560 (prologue_augment): Accept a new bool argument to specify whether to
5561 augment the pre-prologue or post-prologue.
5562 * src/reader.h (before_definitions, after_definitions): Remove these
5563 extern's.
5564 (prologue_augment): Add new bool argument.
5565 * src/scan-gram.l (PERCENT_AFTER_DEFINITIONS): Update to...
5566 (PERCENT_END_HEADER): ... this.
5567 (PERCENT_BEFORE_DEFINITIONS): Update to...
5568 (PERCENT_START_HEADER): ... this.
5569 (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
5570 * tests/actions.at (Printers and Destructors): Update names.
5571
5572 2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
5573
5574 Add comparison operators for C++ location classes. Discussed at
5575 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
5576 * data/c++.m4 (b4_define_location_comparison): New boolean %define
5577 declaration indicating whether filename_type has an operator==. If
5578 filename_type is `std::string', it defaults to `1', `0' otherwise.
5579 * data/location.cc: Iff b4_define_location_comparison is `1', add
5580 operator== and operator!= for class position and for class location.
5581
5582 Some minor fixes.
5583 * src/scan-action.l: Remove unused file.
5584 * src/symtab.c (symbol_printer_set): Use printer_location not
5585 destructor_location.
5586 * src/symtab.h (struct symbol): Replace incorrect source comment for
5587 printer members.
5588 * tests/input.at (Incompatible Aliases): Update output with correct
5589 printer location.
5590
5591 2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
5592
5593 Don't put the pre-prologue in the header file. For the yacc.c code
5594 file and the glr.c header and code files, move the pre-prologue before
5595 the token definitions. Add new %before-definitions and
5596 %after-definitions to declare code that will go in both the header file
5597 and code file. Discussed at
5598 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
5599 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,
5600 and
5601 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00055.html>.
5602 * NEWS (2.3+): Describe these changes.
5603 * data/glr.c (b4_pre_prologue): Move from within to before...
5604 (b4_shared_declarations): ... this.
5605 Add new b4_before_definitions before b4_token_enums.
5606 Add new b4_after_definitions at the end.
5607 * data/glr.cc (b4_pre_prologue): Replace with...
5608 (b4_before_definitions): ... this in the header file.
5609 (b4_after_definitions): New near the end of the header file.
5610 * data/lalr1.cc (b4_pre_prologue): Move from the header file to the
5611 code file right before including the header file.
5612 (b4_before_definitions): New in the previous position of
5613 b4_pre_prologue in the header file.
5614 (b4_after_definitions): New near the end of the header file.
5615 * data/yacc.c: Clean up some m4 quoting especially in the header file.
5616 (b4_token_enums_defines): In the code file, move to right before
5617 YYSTYPE for consistency with the header file.
5618 (b4_before_definitions): New right before b4_token_enums_defines in
5619 both the header and code file.
5620 (b4_after_definitions): New right after YYLTYPE and yylloc in both the
5621 header and code file.
5622 * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
5623 of prologues for %union dependencies.
5624 (Decl Summary): In %defines description, mention the effect of
5625 %before-definitions and %after-definitions on the header file.
5626 (Calc++ Parser): Forward declare driver in a %before-definitions rather
5627 than in the pre-prologue so that make check succeeds.
5628 (Table of Symbols): Add entries for %before-definitions and
5629 %after-definitions.
5630 * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
5631 %before-definitions.
5632 (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
5633 (declaration): Parse those declarations and append to
5634 b4_before_definitions and b4_after_definitions, respectively.
5635 * src/reader.c (before_definitions, after_definitions): New bools to
5636 track whether those declarations have been seen.
5637 (prologue_augment): Add to the post-prologue if %union,
5638 %before-definitions, or %after-definitions has been seen.
5639 * src/reader.h (before_definitions, after_definitions): New extern's.
5640 * src/scan-gram.l: Scan the new declarations.
5641 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
5642 prologue block in a %before-definitions or a %after-definitions based
5643 on whether the %union is declared.
5644 * tests/regression.at (Early token definitions with --yacc, Early token
5645 definitions without --yacc): Move tests for token definitions into the
5646 post-prologue since token names are no longer defined in the
5647 pre-prologue.
5648
5649 2006-06-20 Akim Demaille <akim@epita.fr>
5650
5651 * src/symtab.h, src/symtab.c (symbol_from_uniqstr): New.
5652 (symbol_get): Use it.
5653 * src/parse-gram.y: Use it.
5654
5655 2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
5656
5657 * src/scan-gram.l: Remove unused declaration of last_string_1 so the
5658 build succeeds when configured with --enable-gcc-warnings.
5659
5660 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
5661
5662 * src/parse-gram.y (char_name): New function.
5663 (CHAR, STRING, string_content): For %printer, properly escape.
5664 (ID): Prefer fputs to fprintf.
5665 (id): Reindent to be consistent with other rules.
5666 Properly quote char.
5667
5668 The Translation Project changed its way of publishing translations
5669 to maintainers. I haven't received any responses to my request
5670 for supporting the old way, or for documenting the new way. I
5671 have modified 'bootstrap' to use screen scraping
5672 (in this case, HTML scraping). This is unreliable and inelegant,
5673 but I don't see any better way. Yuck.
5674 * bootstrap (TP_URL, WGET_COMMAND): New vars.
5675 (get_translations): New function, which uses HTML scraping to
5676 deduce locations of latest translations.
5677 Use this function to grab both bison and bison-runtime .po files.
5678 Don't bother priming the pump for the runtime-po domain any more,
5679 as it's now translated better than bison is.
5680
5681 2006-06-19 Akim Demaille <akim@epita.fr>
5682
5683 * src/scan-gram.l: No longer "parse" things after `%union' until
5684 `{'. Rather, return a single "%union" token.
5685 No longer make symbols: return strings, and leave the conversion
5686 to symbols to the parser.
5687 (SC_PRE_CODE, token_type): Remove.
5688 * src/parse-gram.y (%union): New field `character'.
5689 Sort tokens.
5690 (CHAR): New token.
5691 (ID, ID_COLON): Now that the scanner no longer makes them
5692 identifiers, adjust all uses to invoke symbol_get.
5693 (id_colon): New, wraps the conversion from string to symbol.
5694 (%union): Accept a possible union_name.
5695 (symbol): Now can be a char.
5696 * data/c.m4 (b4_union_name): Leave a default value.
5697 * data/glr.c, data/yacc.c: Use it.
5698
5699 2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
5700
5701 For associating token numbers with token names for "yacc.c", don't use
5702 #define statements unless `--yacc' is specified; always use enum
5703 yytokentype. Most important discussions start at:
5704 <http://lists.gnu.org/archive/html/bison-patches/2005-09/msg00053.html>,
5705 <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00052.html>,
5706 and
5707 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00043.html>.
5708 * NEWS (2.3+): Mention.
5709 * data/c.m4 (b4_yacc_if): New.
5710 (b4_token_enums_defines): Use b4_yacc_if to decide whether to add the
5711 token #define's.
5712 * doc/bison.texinfo (Bison Options): Describe the effect of `--yacc'
5713 on token name definitions.
5714 * src/getargs.c (usage): Capitalize `Yacc' in English.
5715 * src/output.c (prepare): Define b4_yacc_flag.
5716 * tests/regression.at (Early token definitions): Test that tokens names
5717 are defined before the pre-prologue not just before the post-prologue.
5718 Remove this test case and copy to...
5719 (Early token definitions with --yacc): ... this to test #define's.
5720 (Early token definitions without --yacc): ... and this to test enums.
5721
5722 2006-06-11 Paul Eggert <eggert@cs.ucla.edu>
5723
5724 * NEWS: Reword the post-2.3 change to not be so optimistic about
5725 removing the old "look-ahead" spelling.
5726 Update previous look-ahead/lookahead change reports.
5727 * REFERENCES: look-ahead -> lookahead (since that's
5728 what he actually wrote).
5729 * doc/refcard.tex: look ahead -> lookahead,
5730 look-ahead -> lookahead
5731
5732 2006-06-09 Joel E. Denny <jdenny@ces.clemson.edu>
5733
5734 For consistency, use `lookahead' instead of `look-ahead' or
5735 `look_ahead'. Discussed starting at
5736 <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00049.html>
5737 and then at
5738 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00017.html>.

5811 * TODO: Add request from Nelson H. F. Beebe to be able to install
5812 Bison without installing the yacc script.
5813
5814 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5815
5816 * src/flex-scanner.h: For the sake of Flex 2.5.4, don't #define yyleng
5817 and yytext if they're already #define'd.
5818 * src/flex-scanner.h, src/location.h: Move #include "system.h" to...
5819 * src/scan-code-c.c: ... here.
5820 * src/scan-code.l, src/scan-gram.l: ... and here. Also #include
5821 <config.h>.
5822
5823 2006-06-07 Joel E. Denny <jdenny@ces.clemson.edu>
5824
5825 Get Bison to build again when configured with --enable-gcc-warnings.
5826 * src/location.c, src/location.h, src/main.c, src/scan-code.l: Add some
5827 missing #include's.
5828 * src/scan-code.l (handle_action_dollar, handle_action_at): Rename
5829 loc argument as it shadows a global.
5830 * src/scan-gram.l: Remove stray comma that prevents boundary_set
5831 invocation.
5832
5833 * src/.cvsignore: Add scan-code.c.
5834
5835 2006-06-07 Akim Demaille <akim@epita.fr>
5836
5837 * src/scan-gram.l: Move the "add a trailing ; to actions" code
5838 to...
5839 * src/scan-code.l: here.
5840 * tests/input.at (Torturing the Scanner): Fix another location
5841 error.
5842
5843 2006-06-07 Akim Demaille <akim@epita.fr>
5844
5845 * src/Makefile.am (BUILT_SOURCES): Fix the trailing backslash.
5846
5847 2006-06-06 Akim Demaille <akim@epita.fr>
5848
5849 Extract the parsing of user actions from the grammar scanner.
5850 As a consequence, the relation between the grammar scanner and
5851 parser is much simpler. We can also split "composite tokens" back
5852 into simple tokens.
5853 * src/gram.h (ITEM_NUMBER_MAX, RULE_NUMBER_MAX): New.
5854 * src/scan-gram.l (add_column_width, adjust_location): Move to and
5855 rename as...
5856 * src/location.h, src/location.c (add_column_width)
5857 (location_compute): these.
5858 Fix the column count: the initial column is 0.
5859 (location_print): Be robust to ending column being 0.
5860 * src/location.h (boundary_set): New.
5861 * src/main.c: Adjust to scanner_free being renamed as
5862 gram_scanner_free.
5863 * src/output.c: Include scan-code.h.
5864 * src/parse-gram.y: Include scan-gram.h and scan-code.h.
5865 Use boundary_set.
5866 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_INITIAL_ACTION)
5867 (PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Remove the {...} part,
5868 which is now, again, a separate token.
5869 Adjust all dependencies.
5870 Whereever actions with $ and @ are used, use translate_code.
5871 (action): Remove this nonterminal which is now useless.
5872 * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.
5873 (grammar_current_rule_action_append): Use translate_code.
5874 (packgram): Bound check ruleno, itemno, and rule_length.
5875 * src/reader.h (gram_in, gram__flex_debug, scanner_cursor)
5876 (last_string, last_braced_code_loc, max_left_semantic_context)
5877 (scanner_initialize, scanner_free, scanner_last_string_free)
5878 (gram_out, gram_lineno, YY_DECL_): Move to...
5879 * src/scan-gram.h: this new file.
5880 (YY_DECL): Rename as...
5881 (GRAM_DECL): this.
5882 * src/scan-code.h, src/scan-code.l, src/scan-code-c.c: New.
5883 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
5884 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
5885 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
5886 Move these declarations, and...
5887 (obstack_for_string, STRING_GROW, STRING_FINISH, STRING_FREE):
5888 these to...
5889 * src/flex-scanner.h: this new file.
5890 * src/scan-gram.l (rule_length, rule_length_overflow)
5891 (increment_rule_length): Remove.
5892 (last_braced_code_loc): Rename as...
5893 (gram_last_braced_code_loc): this.
5894 Adjust to the changes of the parser.
5895 Move all the handling of $ and @ into...
5896 * src/scan-code.l: here.
5897 * src/scan-gram.l (handle_dollar, handle_at): Remove.
5898 (handle_action_dollar, handle_action_at): Move to...
5899 * src/scan-code.l: here.
5900 * src/Makefile.am (bison_SOURCES): Add flex-scanner.h,
5901 scan-code.h, scan-code-c.c, scan-gram.h.
5902 (EXTRA_bison_SOURCES): Add scan-code.l.
5903 (BUILT_SOURCES): Add scan-code.c.
5904 (yacc): Be robust to white spaces.
5905
5906 * tests/conflicts.at, tests/input.at, tests/reduce.at,
5907 * tests/regression.at: Adjust the column numbers.
5908 * tests/regression.at: Adjust the error message.
5909
5910 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5911
5912 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5913 Use Akim's wording from
5914 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00056.html>.
5915
5916 2006-06-06 Joel E. Denny <jdenny@ces.clemson.edu>
5917
5918 Between Bison releases, manually append `+' to the previous Bison
5919 release number, and use that as a signal to automatically print the
5920 ChangeLog's CVS Id keyword from --version. Discussed starting at
5921 <http://lists.gnu.org/archive/html/bison-patches/2006-05/msg00028.html>.
5922 * ChangeLog: Add Id header.
5923 * configure.ac (AC_INIT): Append `+' to `2.3'.
5924 * src/.cvsignore: Add revision.c.
5925 * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
5926 (BUILT_SOURCES): Add revision.c.
5927 (revision.c): New target rule. This file defines a new global variable
5928 named revision. It initializes it with either the Id from ChangeLog
5929 or, if VERSION doesn't contain `+', with the empty string.
5930 * src/getargs.c (version): Print the value of revision.
5931 * src/revision.h: Extern revision.
5932
5933 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
5934
5935 * NEWS: Version 2.3.
5936 * configure.ac (AC_INIT): Likewise.
5937
5938 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
5939
5940 * data/glr.c (YYRECOVERING): Define to be a function-like macro
5941 with no arguments, not as an object-like macro. This is for
5942 compatibility with data/yacc.c. Problem reported by John P. Hartmann in
5943 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
5944 * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):
5945 Document this.
5946
5947 2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
5948
5949 * src/getargs.c (usage): Back out yesterday's modification of the
5950 --help output so that we don't have to wait for translation before
5951 releasing 2.3.
5952
5953 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
5954
5955 * doc/bison.texinfo (Introduction): Don't say "GLR grammar".
5956 Problem reported by Akim Demaille.
5957
5958 2006-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
5959
5960 * src/getargs.c (usage): Mention GLR not just LALR(1) in --help output.
5961
5962 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
5963
5964 * data/yacc.c (yy_reduce_print): Omit trailing white space in
5965 generated source code. Problem reported by Frans Englich in
5966 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.
5967
5968 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
5969
5970 * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
5971 shell, not within 'make', so that 'make' by an ordinary builder
5972 (using GNU make) does not worry about configuring gzip. This also
5973 works around a bug reported independently by Keith Thompson and by
5974 Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
5975 stderr rather than stdout, messing up the build logs.
5976
5977 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5978
5979 * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
5980 to make sure that YYID will never be unused. This fixes a 'make
5981 maintainer-check' failure caused by the recent changes to the 'Trivial
5982 grammars' test case, which caused g++ 4.1.0 to complain that YYID was
5983 not used.
5984 * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
5985
5986 2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
5987
5988 * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
5989 state before an empty RHS is always resolved here. Only the location
5990 of that state is guaranteed to be resolved, and that's enough. This
5991 fixes the remaining bug reported by Derek M. Jones in
5992 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
5993 * tests/glr-regression.at (Uninitialized location when reporting
5994 ambiguity): Test the above case.
5995 Also, the embedded comments in this test case claim it checks the case
5996 of an empty RHS that has inherited the initial location. However, the
5997 corresponding LHS was already resolved, so yyresolveLocations didn't
5998 actually have reason to modify it. Fix this by forcing
5999 nondeterministic operation at the beginning of the parse.
6000
6001 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
6002
6003 * data/c.m4 (b4_yy_symbol_print_generate):
6004 (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
6005 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
6006 of the bugs reported today by Derek M Jones in
6007 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
6008 * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
6009 defined to be a type name without parens or brackets.
6010 (Location Type): Similarly for YYLTYPE.
6011 * tests/regression.at (Trivial grammars): Put in a test for this
6012 bug that will be caught by 'make maintainer-check' (though not,
6013 alas, by 'make check' unless your compiler is picky).
6014
6015 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
6016
6017 * NEWS: Version 2.2.
6018 * configure.ac (AC_INIT): Likewise.
6019
6020 2006-05-17 Joel E. Denny <jdenny@ces.clemson.edu>
6021
6022 * data/glr.c (yyreportTree): Make room in yystates for the state
6023 preceding the RHS. This fixes the segmentation fault reported by Derek
6024 M. Jones in
6025 <http://lists.gnu.org/archive/html/help-bison/2006-05/msg00035.html>.
6026 (yyreportTree, yypdumpstack): Subtract 1 from yyrule before printing
6027 to the user. Reported for yyreportTree by Derek M. Jones later in the
6028 same thread.
6029 * THANKS: Add Derek M. Jones.
6030 Update my email address.
6031 Fix typo in Steve Murphy's name.
6032
6033 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
6034
6035 * data/glr.c (yyreportSyntaxError): Fix off-by-one error in
6036 checking against YYLAST that caused the parser to miss a potential
6037 alternative in its diagnostic.
6038 Problem reported by Maria Jose Moron Fernandez in
6039 <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00024.html>.
6040 * data/lalr1.cc (yysyntax_error_): Likewise.
6041 * data/yacc.c (yysyntax_error): Likewise.
6042 * tests/regression.at (_AT_DATA_DANCER_Y): Use static array for
6043 tokens, in case we run into an older C compiler.
6044 (_AT_DATA_EXPECT2_Y, AT_CHECK_EXPECT2): New macros.
6045 Use them to check for the off-by-one error fixed above.
6046
6047 * data/yacc.c (yytnamerr): Fix typo: local var should be of type
6048 YYSIZE_T, not size_t.
6049 * tests/regression.at (Trivial grammars): New test, to catch
6050 the error fixed by the above patch.
6051
6052 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6053
6054 * doc/bison.texinfo (C++ Bison Interface): Clarify the naming
6055 scheme.
6056 Reported by Steve Murphy.
6057
6058 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6059
6060 * data/glr.cc, data/lalr1.cc: Using %defines is mandatory.
6061 * data/glr.cc: b4_location_flag is now b4_locations_flag.
6062
6063 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6064
6065 Implement --trace=m4.
6066 * src/getargs.c (trace_types, trace_args): Accept trace_m4.
6067 * src/output.c (output_skeleton): When set, pass -dV to m4.
6068
6069 Factor the handling of flags in m4.
6070 * src/output.c (prepare): Rename the muscle names debug, defines,
6071 error_verbose to debug_flag, defines_flag, error_verbose_flag.
6072 * data/c.m4: Adjust.
6073 (_b4_define_flag_if, b4_define_flag_if, b4_defines_if): New.
6074 Use b4_define_flag_if to define other b4_FLAG_if macros.
6075 (b4_location_if): As a consequence, rename as...
6076 (b4_locations_if): this, for consistency.
6077 Adjust all the skeletons.
6078
6079 2006-05-14 Akim Demaille <akim@lrde.epita.fr>
6080
6081 * etc/bench.pm: Shorten bench names.

6086 * src/getargs.h, src/getargs.c: here.
6087 Sort the flags.
6088 Adjust dependencies.
6089
6090 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
6091
6092 * data/c.m4 (b4_copyright): Put the special exception for Bison
6093 skeletons here, so we don't have to put it in each skeleton. All
6094 uses changed. Suggested by Akim Demaille. Also, wrap the
6095 copyright notice, in case it is longer than 80 columns. Replace
6096 comma by newline after title.
6097
6098 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
6099
6100 * doc/bison.texinfo (Calc++ Scanner): The flex behavior is an
6101 incompatibility, not a bug. Mention that it wasn't fixed as of
6102 flex 2.5.33.
6103
6104 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6105

6107 >>.
6108 Reported by Tommy Nordgren.

6110 2006-05-11 Akim Demaille <akim@lrde.epita.fr>
6111
6112 * data/lalr1.cc (yytranslate_): Rename token as t to avoid clashes
6113 with the member "token".
6114 Reported by Martin Nylin.
6115
6116 2006-05-08 Paul Eggert <eggert@cs.ucla.edu>
6117
6118 * data/glr.c: Switch to Bison 2.2 special-exception language in
6119 the copyright notice. Use more-regular format for titles and
6120 copyright notices.
6121 * data/glr.cc: Likewise.
6122 * data/location.cc: Likewise.
6123 * data/yacc.cc: Likewise.

6130
6131 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
6132
6133 * bootstrap: Comment out the AM_CPPFLAGS line, since we don't use
6134 that variable and the line breaks the bootstrap. Problem reported
6135 by Juan M. Guerrero.
6136

6157 2006-03-13 Paul Eggert <eggert@cs.ucla.edu>
6158
6159 * doc/bison.texinfo: Remove @shorttitlepage stuff; it wasn't used
6160 and didn't really work.
6161 For the index, use @ifnotinfo, not @iftex.
6162 Minor cleanups of spacing and terminology.

6167 of AT_NAME_PREFIX when %name-prefix is not used.
6168
6169 2006-03-12 Akim Demaille <akim@lrde.epita.fr>
6170
6171 Apply --prefix to C++ skeletons too: they change the namespace.
6172 The test suite already exercize these cases.
6173 * data/c++.m4 (b4_namespace): New.
6174 * data/lalr1.cc, data/glr.cc, data/location.cc: Use it instead of `yy'.

6176 * data/yacc.c, data/glr.c: Remove a useless `[]'.
6177 * doc/bison.texinfo: Document it.
6178 (Option Cross Key): Use @multitable in all formats. It looks
6179 nicer, even in TeX outputs.
6180 (Rules): Use the same code whatever the output type is.
6181 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS)
6182 (_AT_BISON_OPTION_POPDEFS): Support AT_NAME_PREFIX.

6204 Fix two nits reported by twlevo, plus one more that I discovered.
6205

6213
6214 Fix some nits reported by twlevo.
6215 * doc/FAQ: Remove ancient Y2K FAQ, replacing it with "secure"
6216 and "POSIX". Use more-modern syntax for URLs. Mention C++
6217 and ask for Java. Don't hardwire OS version numbers. Add
6218 copyright notice.

6226 we're describing capabilities not granting permission.
6227

6229
6230 * data/glr.c (yyresolveLocations): Rename local variables to avoid
6231 shadowing warnings. Use usual patter for iterating through RHS.
6232 * tests/glr-regression.at
6233 (Uninitialized location when reporting ambiguity):
6234 Modify yylex so that it uses its argument, rather than trying
6235 to rely on ARGSUSED (which doesn't work for gcc with warnings).
6236 const char -> char const.
6237
6238 * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
6239 Don't use tabs inside commands; it messes up 'ps'.
6240 Problem reported by twlevo.

6243
6244 * tests/glr-regression.at (Uninitialized location when reporting
6245 ambiguity): New test case.
6246 * data/glr.c (yyresolveLocations): New function, which uses
6247 YYLLOC_DEFAULT.
6248 (yyresolveValue): Invoke yyresolveLocations before reporting an
6249 ambiguity.
6250 * doc/bison.texinfo (Default Action for Locations): Note
6251 YYLLOC_DEFAULT's usage for ambiguity locations.
6252 (GLR Semantic Actions): Cross-reference those notes.
6253
6254 2006-03-04 Joel E. Denny <jdenny@ces.clemson.edu>
6255
6256 * tests/glr-regression.at (Leaked semantic values when reporting
6257 ambiguity): Remove unnecessary union and type declarations.
6258 (Leaked lookahead after nondeterministic parse syntax error): New test
6259 case.
6260 * data/glr.c (yyparse): Check for zero stacks remaining before
6261 attempting to shift the lookahead so that you don't lose it.
6262
6263 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6264
6265 Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
6266 * tests/glr-regression.at (Leaked semantic values when reporting
6267 ambiguity): New test case.
6268 * data/glr.c (yyreportAmbiguity): Invoke yyyerror directly and return
6269 yyabort rather than invoking yyFail, which invokes longjmp. Remove the
6270 now unnecessary yystackp parameter.
6271 (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
6272 destructors can be called.
6273
6274 * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
6275 in existing testcases.
6276
6277 2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
6278
6279 Don't leak semantic values for parent RHS when a user action cuts the
6280 parser, and clean up related code a bit.
6281 * tests/glr-regression.at (Leaked merged semantic value if user action
6282 cuts parse): Rename to...
6283 (Leaked semantic values if user action cuts parse): ... this. Add check
6284 for leaked parent RHS values.
6285 * data/glr.c (yydestroyGLRState): In debugging output, distinguish
6286 between an unresolved state (non-empty chain of semantic options) and
6287 an incomplete one (signaled by an empty chain).
6288 (yyresolveStates): Document the interface. Move all manipulation of a
6289 successfully or unsuccessfully resolved yyGLRState to...
6290 (yyresolveValue): ... here so that yyresolveValue always leaves a
6291 yyGLRState with consistent data and thus is easier to understand.
6292 Remove the yyvalp and yylocp parameters since they are always just
6293 taken from the yys parameter. When reporting a discarded merged value
6294 in debugging output, note that it is incompletely merged. Document the
6295 interface.
6296 (yyresolveAction): If resolving any of the RHS states fails, destroy
6297 them all rather than leaking them. Thus, as long as user actions are
6298 written to clean up the RHS correctly, yyresolveAction always cleans up
6299 the RHS of a semantic option. Document the interface.

6318 ((defined YYMALLOC || defined malloc) && (defined YYFREE ||

6320 declarations of malloc and free, to avoid problems with
6321 incompatible declarations (using 'throw') C++'s stdlib.h. This
6322 should fix Debian bug 340012

6353 CFLAGS="-xarch=generic64" CXX=/opt/SUNWspro/bin/CC
6354 LDFLAGS="-xarch=generic64" with Sun C 5.7 on Solaris 10; this

6364
6365 * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from
6366 nodist_PROGRAMS, since we don't need to actually compile the
6367 example if we're just doing a plain 'make'. This avoids bothering
6368 the installer unnecessarily about problems due to weird C++
6369 compilers.

6374
6375 * tests/headers.at (AT_TEST_CPP_GUARD_H): Use #include <...> rather
6376 than #include "...", and compile with -I'.'. The old method was
6377 not portable, according to Posix and the C standard, and it does
6378 not work with Sun C 5.7, where previous #line directives affect
6379 the working directory used in later #include "..." directives.

6397 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6398 that '#include <string>' works.
6399
6400 * data/lalr1.cc (yytranslate_): No longer inline, to work around a
6401 porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
6402 "warning: sorry: semantics of inline function static data `const
6403 unsigned char translate_table[262]' are wrong (you'll wind up with
6404 multiple copies)".
6405
6406 * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
6407 or, xor to not_, and_, or_, and xor_, respectively. This works
6408 around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
6409 random system header somewhere that includes the equivalent of
6410 <iso646.h>.
6411
6412 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that "$CC
6413 -E" works; it apparently doesn't work with PathScale EKO Compiler
6414 Suite Version 2.0.

6417
6418 During deterministic GLR operation, user actions should be able to
6419 influence the parse by changing yychar. To make this easier to fix and
6420 to make glr.c easier to evolve in general, don't maintain yytoken in
6421 parallel with yychar; just compute yytoken when needed.
6422 * tests/glr-regression.at (Incorrect lookahead during deterministic
6423 GLR): Check that setting yychar in a user action has the intended
6424 effect.
6425 * data/glr.c (yyGLRStack): Remove yytokenp member.
6426 (yyclearin): Don't set *yytokenp.
6427 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
6428 yychar rather than *yytokenp to determine the current lookahead.
6429 Compute yytoken locally when needed.
6430 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
6431 point to.
6432
6433 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
6434 after `--report' documentation.

6438 * src/parse-gram.y (grammar_declaration): Location of printer
6439 symbol is @1, not list->location. Bug reported by twlevo.
6440 * tests/input.at (Incompatible Aliases): Adjust to above change.
6441
6442 2006-01-29 Paul Eggert <eggert@cs.ucla.edu>
6443
6444 * tests/input.at (AT_CHECK_UNUSED_VALUES): Remove. Instead, do
6445 all the test at once. This makes the output easier to read in the
6446 normal case.
6447
6448 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
6449 got from <http://bro-ids.org/download.html>. The bug is that
6450 when two actions appeared in succession, the second one was
6451 scanned before the first one was added to the grammar rule
6452 as a midrule action. Bison then output the incorrect warning
6453 "parse.y:905.17-906.36: warning: unused value: $3".
6454 * src/parse-gram.y (BRACED_CODE, action): These are no longer
6455 associated with a value.
6456 (rhs): Don't invoke grammar_current_rule_action_append.
6457 (action): Invoke it here instead.
6458 * src/reader.c (grammar_midrule_action): Now extern.
6459 (grammar_current_rule_action_append): Don't invoke
6460 grammar_midrule_action; that is now the scanner's job.
6461 * src/reader.h (last_string, last_braced_code_loc):
6462 (grammar_midrule_action): New decls.
6463 * src/scan-gram.l (last_string): Now extern, sigh.
6464 (last_braced_code_loc): New extern variable.
6465 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
6466 rule already has an action.
6467 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
6468 * tests/input.at (AT_CHECK_UNUSED_VALUES):
6469 Add some tests to check that the above changes fixed the bug.
6470
6471 2006-01-27 Paul Eggert <eggert@cs.ucla.edu>
6472
6473 * src/reader.c (symbol_should_be_used): Renamed from symbol_typed_p.
6474 All used changed. Check whether the symbol has a destructor,
6475 not whether it is typed.
6476 * tests/input.at (AT_CHECK_UNUSED_VALUES): Add a destructor, so
6477 that the values are still reported as unused. All line numbers
6478 adjusted.
6479

6485 their arguments.

6491 Work around a bug in Pike 7.0, and give the Pike folks a
6492 better way to override the usual int widths.
6493 * data/yacc.c (b4_int_type): Use yytype_uint8, etc., so that the
6494 user can override the types.
6495 (short): #undef, to work around a bug in Pike 7.0.
6496 (yytype_uint8, yytype_int8, yytype_uint16, yytype_int16): New types.
6497 (union yyalloc.yyss): Use yytype_int16 rather than short.
6498 All uses changed.
6499 (yysigned_char): Remove.
6500 * src/parse-gram.y (YYTYPE_UINT8, YYTYPE_INT8, YYTYPE_UINT16):
6501 (YYTYPE_INT16): New macros, to test the new facility in yacc.c.
6502 * tests/regression.at (Web2c Actions): Adjust to above changes.
6503
6504 * src/reader.c (check_and_convert_grammar): New function.
6505 (reader): Close the input file even if something went wrong during
6506 parsing. Minor file descriptor leak reported by twlevo.
6507
6508 * src/assoc.c (assoc_to_string): Use a default: abort (); case
6509 to pacify gcc -Wswitch-default.
6510 * src/scan-gram.l (adjust_location): Use a default: break; case
6511 to pacify gcc -Wswitch-default.
6512 * src/scan-skel.h (skel_get_lineno, skel_get_in, skel_get_out):
6513 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
6514 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
6515 Move these decls to scan-skel.l, since they don't need to be
6516 visible elsewhere.
6517 * src/scan-skel.l: Accept the above decls.
6518 (skel_lex): New decl, to pacify GCC when unpatched flex 2.5.31
6519 is used.
6520
6521 2006-01-21 Paul Eggert <eggert@cs.ucla.edu>
6522
6523 * Makefile.cfg (local-checks-to-skip): Add changelog-check,
6524 since we don't want to insist on a version number at the start
6525 of the changelog every time.
6526 * Makefile.maint: Sync from coreutils a bit better.
6527 (sc_trailing_blank): Renamed from sc_trailing_space.
6528 All uses changed.
6529 (sc_no_if_have_config_h, sc_require_config_h):

6533 (sc_system_h_headers): Prefix with @.
6534 (sc_useless_cpp_parens, m4-check): Output line numbers.
6535 (changelog-check): Allow version only in head.

6582 * lib/abitset.c (abitset_test): Remove ATTRIBUTE_UNUSED; not needed.
6583 * lib/bitset.c (bitset_bytes, bitset_init, bitset_op4_cmp):
6584 Put 'default: abort ();' before some other case, to satisfy older
6585 pedantic compilers.

6593 (get_linestyle_str, get_arrowstyle_str): Likewise.
6594 * src/conflicts.c (resolve_sr_conflict):
6595 Use a default case rather than one for the one remaining enum
6596 value, to catch invalid enum values as well.
6597 * src/lalr.c (set_goto_map, map_goto):
6598 Prefer "assert (FOO);" to "if (!FOO) abort ();".

6610 (assert): New macro.
6611
6612 * doc/bison.texinfo (Prologue, Rules, Actions, Union Decl, Action Decl):

6617
6618 Fix some porting glitches found by Nelson H. F. Beebe.
6619 * lib/abitset.c (abitset_resize): Rewrite to avoid warnings from
6620 compilers that don't understand that abort () does not return.
6621 * src/state.c (transitions_to): Likewise.
6622 * m4/cxx.m4 (BISON_TEST_FOR_WORKING_CXX_COMPILER): Check
6623 that '#include <cstdlib>' works.
6624 * src/system.h (INT8_MIN, INT16_MIN, INT32_MIN, INT8_MAX):
6625 (INT16_MAX, UINT8_MAX, INT32_MAX, UINT16_MAX, UINT32_MAX):
6626 #undef if ! defined __STDC_VERSION__ || __STDC_VERSION__ < 199901,
6627 for the benefit of some pre-C99 compilers.
6628
6629 * bootstrap: Undo changes to gnulib files that autoreconf made.
6630
6631 Minor fixups to get 'make maintainer-check' to work.
6632 * configure.ac: Don't use -Wnested-externs, as it's incompatible
6633 with the new verify.h implementation.
6634 * data/c.m4 (b4_yy_symbol_print_generate): YYUSE (yyoutput).
6635 * data/glr.c (YYUSE): Depend on __GNUC__ as well.
6636 * data/yacc.c (YYUSE): Likewise.
6637 * data/lalr1.cc (yysyntax_error_): YYUSE (yystate).
6638 * lib/subpipe.c (end_of_output_subpipe): The args are unused.
6639 * src/parse-gram.y (declaration): Don't pass a string constant
6640 to a function that expects char *, since GCC might complain
6641 about the constant value.
6642 * src/reader.c (symbol_typed_p): Add parens to pacify GCC.
6643 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): #undef yylloc and yylval
6644 before #defining them.
6645 * tests/glr-regression.at
6646 (Incorrectly initialized location for empty right-hand side in GLR):
6647 In yyerror, use the msg arg.
6648 (Corrupted semantic options if user action cuts parse):
6649 (Incorrect lookahead during deterministic GLR):
6650 (Incorrect lookahead during nondeterministic GLR):
6651 Don't name a local var 'index'; it shadows string.h's 'index'.
6652
6653 2006-01-19 Akim Demaille <akim@epita.fr>
6654
6655 * tests/calc.at (_AT_DATA_CALC_Y): Initialize the whole initial
6656 location, not just parts of it.
6657
6658 2006-01-18 Paul Eggert <eggert@cs.ucla.edu>
6659
6660 * NEWS: Document the fact that multiple %unions are now allowed.
6661 * doc/bison.texinfo (Union Decl): Likewise.
6662 * TODO: This feature is now implemented, so remove it from
6663 the wishlist.
6664
6665 * Makefile.maint: Merge with coreutils Makefile.maint.
6666 (CVS_LIST): Use build-aux version if available.
6667 (VERSION_REGEXP): New macro.
6668 (syntax-check-rules): Add sc_no_if_have_config_h,
6669 sc_prohibit_assert_without_use, sc_require_config_h,
6670 sc_useless_cpp_parens.
6671 (sc_obsolete_symbols): Check for O_NDELAY.
6672 (sc_dd_max_sym_length): Track coreutils.
6673 (sc_unmarked_diagnostics): Look in all files, not just *.c.
6674 (sc_useless_cpp_parens): New rule.
6675 (news-date-check): Look for version or today's date.
6676 (changelog-check): Don't require version number near head.
6677 (copyright-check): Use current year instead of hardwiring 2005.
6678 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
6679 (announcement): Add --gpg-key-ID.
6680
6681 * djgpp/config.sed: Add copyright notice, and replace "filesystem"
6682 with "file system".
6683
6684 Avoid undefined behavior that addressed just before the start of an
6685 array. Problem reported by twlevo.
6686 * src/reader.c (packgram): Prepend a new sentinel before ritem.
6687 * src/lalr.c (build_relations): Rely on new sentinel.
6688 * src/gram.c (gram_free): Adjust to new sentinel.
6689
6690 2006-01-12 Joel E. Denny <jdenny@ces.clemson.edu>
6691
6692 * data/glr.c (yyGLRStateSet): Rename yylookaheadStatuses to
6693 yylookaheadNeeds. All uses updated.
6694 (yysplitStack): Rename local yynewLookaheadStatuses to
6695 yynewLookaheadNeeds.
6696 * data/glr-regression.at (Incorrect lookahead during nondeterministic
6697 GLR): In comments, change `lookahead status' to `lookahead need'.
6698
6699 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6700
6701 * data/glr.c (yysplitStack): A little stylistic rewrite.
6702
6703 2006-01-11 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
6704
6705 * data/glr.c (yyaddDeferredAction): Flesh out the comment.
6706
6707 2006-01-11 Joel E. Denny <jdenny@ces.clemson.edu>
6708
6709 * doc/bison.texinfo: Fix some typos.
6710 (GLR Semantic Actions): New subsection discussing special
6711 considerations because GLR semantic actions might be deferred.
6712 (Actions): Mention look-ahead usage of yylval.
6713 (Actions and Locations): Mention look-ahead usage of yylloc.
6714 (Special Features for Use in Actions): Add YYEOF entry and mention it
6715 in the yychar entry.
6716 In the yychar entry, remove mention of the local yychar case (pure
6717 parser) since this is irrelevant information when writing semantic
6718 actions and since it's already discussed in `Table of Symbols' where
6719 yychar is otherwise described as an external variable.
6720 In the yychar entry, don't call it the `current' look-ahead since it
6721 isn't when semantic actions are deferred.
6722 In the yychar and yyclearin entries, add note about deferred semantic
6723 actions.
6724 Add yylloc and yylval entries discussing look-ahead usage.
6725 (Look-Ahead Tokens): When discussing yychar, don't call it the
6726 `current' look-ahead, and do mention yylval and yylloc.
6727 (Error Recovery): Cross-reference `Action Features' when mentioning
6728 yyclearin.
6729 (Table of Symbols): In the yychar entry, don't call it the `current'
6730 look-ahead.
6731 In the yylloc and yylval entries, mention look-ahead usage.
6732
6733 2006-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
6734
6735 * tests/glr-regression.at: Update copyright year to 2006.
6736
6737 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6738
6739 * data/glr.c (yyGLRStateSet): Add yybool* yylookaheadStatuses member to
6740 use during nondeterministic operation to track which stacks have
6741 actually needed the current lookahead.
6742 (yyinitStateSet, yyfreeStateSet, yyremoveDeletes, yysplitStack):
6743 Allocate, deallocate, resize, and otherwise shuffle space for
6744 yylookaheadStatuses in parallel with yystates member of yyGLRStateSet.
6745 (yysplitStack, yyprocessOneStack, yyparse): Set lookahead status
6746 appropriately during nondeterministic operation.
6747 (yySemanticOption): Add int yyrawchar, YYSTYPE yyval, and YYLTYPE yyloc
6748 members to store the current lookahead to be used by the deferred
6749 user action.
6750 (yyaddDeferredAction): Add size_t yyk parameter specifying the stack
6751 from which the RHS is taken. Set the lookahead members of the new
6752 yySemanticOption according to the lookahead status for stack yyk.
6753 (yyglrShiftDefer, yyglrReduce): Pass yyk parameter on to
6754 yyaddDeferredAction.
6755 (yyresolveAction): Set yychar, yylval, and yylloc to the lookahead
6756 members of yySemanticOption before invoking yyuserAction, and then set
6757 them back to their current values afterward.
6758 (yyparse): Set yychar = YYEMPTY where yytoken = YYEMPTY.
6759 (yyreportAmbiguity): Add /*ARGSUSED*/ to pacify lint.
6760 * tests/glr-regression.at: Remove `.' from the ends of recent test case
6761 titles for consistency.
6762 (Leaked merged semantic value if user action cuts parse): In order to
6763 suppress lint warnings, use arguments in merge function, and assign
6764 char value < 128 in main.
6765 (Incorrect lookahead during deterministic GLR): New test case.
6766 (Incorrect lookahead during nondeterministic GLR): New test case.
6767
6768 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6769
6770 * data/c.m4 (b4_yy_symbol_print_generate): In yy_symbol_print, accept
6771 !yyvaluep as signal that no semantic value is available to print.
6772 * data/glr.c (yydestroyGLRState): If state is not resolved, don't try
6773 to print a semantic value.
6774
6775 2006-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
6776
6777 * tests/glr-regression.at: For consistency with my newer test cases,
6778 don't thank myself.
6779
6780 2006-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
6781
6782 * data/glr.c (yyresolveValue): When merging semantic options, if at
6783 least one user action succeeds but a later one cuts the parse, then
6784 destroy the semantic value before returning rather than leaking it.
6785 (yyresolveStates): If a user action cuts the parse and thus
6786 yyresolveValue fails, ignore the (unset) semantic value rather than
6787 corrupting the yyGLRState, and empty the semantic options list since
6788 the user actions should have called all necessary destructors.
6789 Simplify code with YYCHK.
6790 * tests/glr-regression.at (Corrupted semantic options if user action
6791 cuts parse): New test case.
6792 (Undesirable destructors if user action cuts parse): New test case.
6793 Before applying any of this patch, this test case never actually failed
6794 for me... but only because the corrupted semantic options usually
6795 masked this bug.
6796 (Leaked merged semantic value if user action cuts parse): New test
6797 case.
6798
6799 2006-01-05 Akim Demaille <akim@epita.fr>
6800
6801 * src/reader.c, src/symlist.h, src/symlist.c: s/mid_rule/midrule/.

6804
6805 * data/c.m4 (b4_c_modern): New macro, with a new provision for
6806 _MSC_VER. Problem reported by Cenzato Marco.
6807 (b4_c_function_def): Use it.
6808 * data/yacc.c (YYMODERN_C): Remove. All uses replaced by
6809 b4_c_modern.
6810 (yystrlen, yystpcpy, yyparse): Use b4_c_function... macros rather
6811 than rolling our own.
6812
6813 2006-01-04 Akim Demaille <akim@epita.fr>
6814
6815 Also warn about non-used mid-rule values.
6816 * src/symlist.h, src/symlist.c (symbol_list): Add a mid_rule
6817 member.
6818 (symbol_list_new): Adjust.
6819 * src/reader.c (symbol_typed_p): New.
6820 (grammar_rule_check): Use it.
6821 (grammar_midrule_action): Bind a mid-rule LHS to its rule.
6822 Check its rule.
6823 * tests/input.at (AT_CHECK_UNUSED_VALUES): New.
6824 Use it.
6825 * tests/actions.at (Exotic Dollars): Adjust.
6826
6827 2006-01-04 Akim Demaille <akim@epita.fr>
6828
6829 * src/reader.c (grammar_midrule_action): If $$ is set in a
6830 mid-rule, move the `used' bit to its lhs.
6831 * tests/input.at (Unused values): New.
6832 * tests/actions.at (Exotic Dollars): Adjust: exp is not typed.
6833
6834 2006-01-03 Paul Eggert <eggert@cs.ucla.edu>
6835
6836 * doc/bison.texinfo (Bison Options): Say more accurately what
6837 --yacc does.
6838 * src/parse-gram.y (rules_or_grammar_declaration): Don't complain
6839 about declarations in the grammar when in Yacc mode, as POSIX does
6840 not require a diagnostic when the grammar uses extensions.
6841
6842 * src/reduce.c (reduce_grammar): Remove unnecessary cast to bool.
6843
6844 Warn about dubious constructions like "%token T T".
6845 Reported by twlevo.
6846 * src/symtab.h (struct symbol.declared): New member.
6847 * src/symtab.c (symbol_new): Initialize it to false.
6848 (symbol_class_set): New arg DECLARING, specifying whether
6849 this is a declaration that we want to warn about, if there
6850 is more than one of them. All uses changed.
6851
6852 * data/glr.c, data/glr.cc, data/lalr1.cc, data/yacc.c:
6853 Allow multiple %union directives, whose contents concatenate.
6854 * src/parse-gram.y (grammar_declaration): Likewise.
6855 Use muscle_code_grow, so that we don't need stype_line any more.
6856 All uses changed.
6857
6858 * src/muscle_tab.c (muscle_grow): Fix comment.
6859
6860 * ChangeLog, data/c.m4, data/glr.c, data/glr.cc, data/location.cc:
6861 * data/yacc.c, src/getargs.c, src/output.c, tests/cxx-type.at:
6862 Update copyright year to 2006.
6863
6864 2006-01-03 Akim Demaille <akim@epita.fr>
6865
6866 Have glr.cc pass (some of) the calc.at tests.
6867 * data/glr.cc (b4_parse_param_orig): New.
6868 (b4_parse_param): Improve its definition, and bound it more
6869 clearly in the skeleton.
6870 (b4_epilogue): Append, instead of prepending, in order to keep
6871 #line consistency.
6872 Simplify the generation of auxiliary functions: locations and
6873 purity are mandated.
6874 (b4_global_tokens_and_yystype): Honor it.
6875 * data/location.cc (c++.m4): Don't include it.
6876 * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
6877 and AT_SKEL_CC_IF.
6878 * tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
6879 AT_LALR1_CC_IF.
6880 Be sure to initialize the first position's filename.
6881 (AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
6882 mandated anyway.
6883 (AT_CHECK_CALC_GLR_CC): New.
6884 Use it to exercise glr.cc as a lalr1.cc drop-in replacement.
6885
6886 2006-01-02 Akim Demaille <akim@epita.fr>
6887
6888 * src/output.c (output_skeleton): Don't hard wire the inclusion of
6889 c.m4.
6890 * data/c++.m4, data/glr.c, data/yacc.c: Include c.m4.
6891 * data/glr.cc: Do not include stack.hh.
6892
6893 2006-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
6894
6895 * data/glr.c: Reformat whitespace with tabs.
6896 (b4_lpure_formals): Remove this unused m4 macro.
6897 * tests/cxx-type.at: Reformat whitespace with tabs.
6898 (_AT_TEST_GLR_CXXTYPES): In union Node, rename node_info to nodeInfo
6899 since it's a member. Rename type to isNterm for clarity.
6900
6901 2005-12-29 Akim <akim@sulaco.local>
6902
6903 Let glr.cc catch up with symbol_value_print.
6904 * data/glr.cc (b4_yysymprint_generate): Replace by...
6905 (b4_yy_symbol_print_generate): this.
6906 (yy_symbol_print, yy_symbol_value_print): Declare them.
6907
6908 2005-12-28 Paul Eggert <eggert@cs.ucla.edu>
6909
6910 * src/location.h (boundary): Note that a line or column equal
6911 to INT_MAX indicates an overflow.
6912 * src/scan-gram.l: Include verify.h. Don't include get-errno.h.
6913 (rule_length_overflow, increment_rule_length, add_column_width):
6914 New functions.
6915 (<INITIAL>{id}, <SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'"):
6916 (<SC_BRACED_CODE>"}"):
6917 Use increment_rule_length rather than incrementing it by hand.
6918 (adjust_location, handle_syncline): Diagnose overflow.
6919 (handle_action_dollar, handle_action_at):
6920 Fix bug with monstrosities like $-2147483648.
6921 Remove now-unnecessary checks.
6922 (scan_integer): Verify assumptions and remove now-unnecessary checks.
6923 (convert_ucn_to_byte): Verify assumptions.
6924 (handle_syncline): New arg LOC. All callers changed.
6925 Don't store through a value derived from char const * pointer.
6926
6927 * src/reader.c (grammar_rule_check): Rewrite slightly to avoid
6928 GCC warnings.
6929
6930 2005-12-27 Paul Eggert <eggert@cs.ucla.edu>
6931
6932 * src/reader.c (grammar_midrule_action, grammar_symbol_append):
6933 Remove unnecessary forward static decls.
6934
6935 2005-12-27 Akim Demaille <akim@epita.fr>
6936
6937 * src/reader.c (grammar_current_rule_check): Also check that $$
6938 is used.
6939 Take the rule to check as argument, hence rename as...
6940 (grammar_rule_check): this.
6941 * src/reader.h, src/reader.c (grammar_rule_begin, grammar_rule_end):
6942 Rename as...
6943 (grammar_rule_begin, grammar_rule_end): these, for consistency.
6944 (grammar_midrule_action, grammar_symbol_append): Now static.
6945 * tests/torture.at (input): Don't rely on the default action
6946 being always performed.
6947 * tests/calc.at: "Set" $$ even when the action is "cut" with
6948 YYERROR or other.
6949 * tests/actions.at (Exotic Dollars): Instead of using unused
6950 values, check that the warning is issued.
6951
6952 2005-12-22 Paul Eggert <eggert@cs.ucla.edu>
6953

6965
6966 * NEWS: Warn about unused values.
6967 * src/symlist.h, src/symlist.c (symbol_list, symbol_list_new): Add

6975 * tests/existing.at: Remove the type information.
6976 Empty the actions.
6977 Remove useless actions (beware of mid-rule actions: perl -000
6978 -pi -e 's/\s*\{\}(?=[\n\s]*[|;])//g').
6979 * tests/actions.at (Exotic Dollars): Use unused values.
6980 * tests/calc.at: Likewise.
6981 * tests/glr-regression.at (No users destructors if stack 0 deleted):
6982 Likewise.
6983
6984 * src/gram.c (rule_useful_p, rule_never_reduced_p): Use
6985 rule_useful_p.
6986
6987 2005-12-21 Paul Eggert <eggert@cs.ucla.edu>
6988
6989 Undo 2005-12-01 tentative license wording change. The wording is
6990 still being reviewed by the lawyers, and we don't want to wait for
6991 them before publishing a test release. For now, revert to the
6992 previous wording.
6993 * NEWS: Undo 2005-12-01 change.
6994 * data/glr.c: Revert to previous license wording.
6995 * data/glr.cc: Likewise.
6996 * data/lalr1.cc: Likewise.
6997 * data/location.cc: Likewise.
6998 * data/yacc.c: Likewise.
6999
7000 * NEWS: Reword %destructor vs YYABORT etc.
7001 * data/glr.c: Use American spacing, for consistency.
7002 * data/glr.cc: Likewise.
7003 * data/lalr1.cc: Likewise.
7004 * data/yacc.c: Likewise.
7005 * data/yacc.c: Reformat comments slightly.
7006 * doc/bison.texinfo: Replace "non-" with "non" when that makes sense,
7007 for consistency. Fix some spelling errors and reword recently-included
7008 text slightly.
7009 * tests/cxx-type.at: Cast results of malloc, for C++.
7010
7011 2005-12-21 Joel E. Denny <address@hidden>
7012
7013 * tests/cxx-type.at: Construct a tree, count the parents of shared
7014 nodes, and free each node once and only once. Previously, the memory
7015 for semantic values was leaked instead.
7016
7017 2005-12-21 Joel E. Denny <address@hidden>
7018
7019 * data/glr.c (struct yyGLRStack): If pure, add yyval and yyloc members.
7020 (yylval, yylloc): If pure, #define to yystackp->yyval and
7021 yystackp->yyloc similar to yychar and yynerrs.
7022 (yyparse): If pure, remove local yylval and yylloc. Add local
7023 yystackp to accommodate pure definitions of yylval and yylloc.
7024 (b4_lex_param, b4_lyyerror_args, b4_lpure_args): If pure, change
7025 yylvalp and yyllocp to &yylval and &yylloc.
7026 (nerrs, char, lval, lloc): If pure, add #define's for b4_prefix[]
7027 namespace. Previously, nerrs and char were missing, but lval and lloc
7028 weren't necessary.
7029 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Remove
7030 yylvalp and yyllocp parameters since, if pure, these are now always
7031 accessible through yystackp. If not pure, they are still accessible
7032 globally.
7033 * data/glr.c, data/yacc.c (YYLLOC_DEFAULT): Change `if (N)' to
7034 `if (YYID (N))' to pacify lint.
7035
7036 2005-12-21 Akim Demaille <akim@epita.fr>
7037
7038 YYACCEPT, YYERROR, and YYABORT, as user actions, should not
7039 destroy the RHS symbols of a rule.
7040 * data/yacc.c (yylen): Initialize to 0.
7041 Keep its value to the number of items to possibly shift.
7042 In particular, a regular successful parse that ends on YYFINAL by
7043 a (internal) YYACCEPT must not have yylen != 0.
7044 (yyerrorlab, yyreturn): Pop the RHS.
7045 Reorder a bit to emphasize the `shifting' bits of code.
7046 (YYPOPSTACK): Now accept a number of items to pop.
7047 * data/lalr1.cc: Likewise.
7048 * data/glr.c: Formatting changes.
7049 Use goto instead of fall through.
7050 * doc/bison.texinfo (Destructor Decl): Complete.
7051
7052 2005-12-20 Juan Manuel Guerrero <juan.guerrero@gmx.de>
7053
7054 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
7055 * djgpp/Makefile.maint: Fix PACKAGE variable computation.
7056 * djgpp/config.bat: Replace every occurence of the file name
7057 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
7058 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
7059 * djgpp/config.sed: Replace every occurence of the file name
7060 scan-gram-c.c with c-scan-gram.c. The same for scan-skel-c.c with
7061 c-scan-skel.c to conform with the 8.3 file name restriction on MSDOS.
7062 * djgpp/djunpack.bat: DJGPP specific file.
7063 * djgpp/fnchange.lst: DJGPP specific file.
7064 * djgpp/README.in: Add new information about how to unpack the bison
7065 source on MSDOS and other systems which have 8.3 file name restrictions
7066 using djunpack.bat and fnchange.lst.

7068 2005-12-12 Paul Eggert <eggert@cs.ucla.edu>
7069
7070 * bootstrap (build_cvs_prefix): Remove; unused.
7071 (CVS_PREFIX): Adjust to yesterday's Savannah reorganization
7072 when getting gnulib.
7073
7074 2005-12-12 "Joel E. Denny" <jdenny@ces.clemson.edu>
7075
7076 * data/glr.c: Reorder typedef declarations for structs to match order
7077 of struct declarations.
7078 Rename yystack everywhere to yystackp except in yyparse where it's not
7079 a pointer.
7080 (yyglrShift): Change parameter YYSTYPE yysval to YYSTYPE* yyvalp for
7081 consistency.
7082 (yyis_table_ninf): Change 0 to YYID (0) to pacify lint.
7083 (yyreportSyntaxError): Add /*ARGSUSED*/ to pacify lint.

7088
7089 * tests/sets.at (Accept): Fix typos in regular expression used to
7090 sed out the final state number.
7091
7092 Work around portability problem on Solaris 10: flex-generated
7093 files include <stdio.h> before <config.h>, which messes up
7094 because the latter defines __EXTENSIONS__. Address the problem
7095 by creating two new little files that include <config.h> first,
7096 then include the flex-generated files. Rewrite everyone else
7097 to include <config.h> first, as well.
7098 * lib/timevar.c: Always include "config.h".
7099 * src/Makefile.am (bison_SOURCES): Replace scan-gram.l with

7133 (current_lhs, current_lhs_location): Now static.
7134 (current_assoc): Remove unused variable.
7135
7136 Cleanups so that Bison-generated parsers have less lint.
7137 * data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
7138 Prepend /*ARGSUSED*/, for lint's sake.
7139 * data/glr.c (YYUSE): Properly parenthesize, and use an alternate
7140 definition if 'lint' is defined.
7141 (YYID): New macro (or function, if lint).
7142 All uses of /*CONSTCOND*/0 replaced by YYID(0).
7143 * data/yacc.c: Likewise.
7144 * data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
7145 (yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
7146 * data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
7147 is C++ only.
7148 * data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
7149 * data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
7150 Use YYID(0) rather than 0, for lint.
7151 (yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
7152 (yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
7153
7154 2005-12-07 Paul Eggert <eggert@cs.ucla.edu>

7166 New test case.
7167 (Duplicated user destructor for lookahead): This test now is expected
7168 to succeed.
7169
7170 2005-12-01 Paul Eggert <eggert@cs.ucla.edu>
7171
7172 * NEWS: Document the following change.
7173 * data/yacc.c: Say "parser skeleton" rather than "file", since
7174 it's no longer just a file.
7175 * data/glr.c: Grant a special exception for C GLR parsers, that
7176 reads like the already-existing exception for C LALR(1) parsers.
7177 * data/glr.cc: Likewise.
7178 * data/lalr1.cc: Likewise.
7179 * data/location.cc: Likewise.
7180 * data/yacc.c: Reword the "written by" statement to clarify that
7181 it was the parser skeleton, not the entire output file.
7182 * data/glr.c: Written by Paul Hilfinger.
7183 * data/glr.cc: Written by Akim Demaille.
7184 * data/lalr1.cc: Likewise.
7185
7186 2005-11-18 Paul Eggert <eggert@cs.ucla.edu>
7187
7188 * data/yacc.c (yy_reduce_print, YY_REDUCE_PRINT):
7189 Fix typos in previous change that broke 'make check'.
7190 YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
7191 supported in C.
7192 * tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
7193 Don't check NUM-STDERR-LINES, since the output format is fluctuating.
7194 We can revert this once things settle down.
7195
7196 * src/conflicts.c (conflicts_print): Don't print file name twice
7197 when %expect fails because there were no conflicts.
7198 * doc/bison.texinfo (Expect Decl): Tighten up wording in previous
7199 change.
7200 * tests/conflicts.at (%expect not enough, %expect too much):
7201 (%expect with reduce conflicts): Adjust to new behavior.
7202

7224
7225 2005-11-14 Akim Demaille <akim@epita.fr>
7226
7227 * data/glr.c (yy_reduce_print): The loop was quite wrong: type are
7228 from 1 to N, while values and location start at 0.
7229 (b4_rhs_location, b4_rhs_value): Add parens around $1 and $2.
7230
7231 2005-11-14 Akim Demaille <akim@epita.fr>
7232
7233 * data/glr.c (yy_reduce_print): Fix the $ number.

7241 non-pointer types.
7242
7243 2005-11-14 Akim Demaille <akim@epita.fr>
7244
7245 * data/glr.c (yyexpandGLRStack): Declare only if defined.

7257 b4_location_constructors is defined.
7258 * data/lalr1.cc (b4_location_constructors): Define it for backward
7259 compatibility.
7260 * doc/bison.texinfo (Initial Action Decl): Use initialize.
7261
7262 2005-11-12 Akim Demaille <akim@epita.fr>
7263
7264 * data/lalr1.cc: Move the body of the ctor and dtor into the
7265 parser file (instead of the header).
7266 Wrap the implementations in a "namespace yy".

7268 2005-11-12 Akim Demaille <akim@epita.fr>
7269
7270 Have glr.c include its header file when created.
7271 * data/glr.c (b4_shared_declarations): New.
7272 Output them verbatim in the parser if !%defines, otherwise
7273 output then in the header file, and include it instead.
7274
7275 2005-11-11 Akim Demaille <akim@epita.fr>
7276
7277 * data/glr.c: Comment changes.

7279 2005-11-11 Akim Demaille <akim@epita.fr>
7280
7281 When yydebug, report semantic and location values for reductions.

7297 2005-11-09 Albert Chin-A-Young <china@thewrittenword.com>
7298
7299 * m4/cxx.m4, examples/Makefile.am: Don't build
7300 examples/calc++ if no C++ compiler is available. (trivial change)
7301
7302 2005-11-09 Akim Demaille <akim@epita.fr>
7303
7304 * src/scan-skel.l: Use a couple of asserts.
7305
7306 2005-11-03 Akim Demaille <akim@epita.fr>
7307
7308 In some (weird) cases, the final state number is incorrect.
7309 Reported by Alexandre Duret-Lutz.
7310 * src/LR0.c (state_list_append): Remove the computation of
7311 final_state.
7312 (save_reductions): Do it here.
7313 (get_state): Alpha conversion.
7314 (generate_states): Use a for loop.

7323 * data/glr.c (yyfill): Adjust comment.
7324 (yyresolveAction): Initialize default location properly
7325 for empty right-hand sides.
7326 (yydoAction): Ditto.
7327 Add comment explaining apparently dead code.
7328 * tests/glr-regression.at
7329 (Incorrectly initialized location for empty right-hand side in GLR):
7330 New test.
7331
7332 2005-10-30 Paul Eggert <eggert@cs.ucla.edu>
7333
7334 * bootstrap (cleanup_gnulib): New function. Use it to clean up
7335 gnulib when interrupted. This fixes some race conditions and
7336 works around some portability problems (one noted by Paul
7337 Hilfinger).
7338
7339 2005-10-22 Akim <akim@epita.fr>
7340
7341 * Makefile.cfg: Adjust to config -> build-aux.
7342 Reported by twledo.
7343
7344 2005-10-21 Akim Demaille <akim@epita.fr>
7345

7352 * doc/bison.texinfo: Formatting changes.
7353
7354 2005-10-21 Akim Demaille <akim@epita.fr>
7355
7356 Finish the transition config -> build-aux.
7357 * configure.ac, Makefile.am: Use build-aux.

7359 Move to...
7360 * build-aux/prev-version, build-aux/announce-gen,
7361 * build-aux/Makefile.am: here.
7362
7363 2005-10-14 Akim Demaille <akim@epita.fr>
7364
7365 * examples/calc++/test: Use set -x only when VERBOSE.
7366
7367 2005-10-13 Paul Eggert <eggert@cs.ucla.edu>
7368
7369 * NEWS: Bison now warns if it finds a stray `$' or `@' in an action.
7370 * src/scan-gram.l (<SC_BRACED_CODE>[$@]): Implement this.
7371
7372 2005-10-13 Akim Demaille <akim@epita.fr>
7373
7374 * src/scan-skel.l: Output the base name parts of the parser and
7375 header file names.
7376 * tests/output.at (AT_CHECK_OUTPUT): Support subdirectories, and
7377 additional checks.
7378 Use this to exercise C++ outputs in subdirs.
7379 Reported by Oleg Smolsky.
7380
7381 2005-10-12 Paul Eggert <eggert@cs.ucla.edu>
7382
7383 * data/c.m4 (b4_c_function_def): Look at __C99_FUNC__, not at
7384 __STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
7385 Problem reported by John P. Hartmann.
7386 * data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
7387 already defined it.
7388
7389 2005-10-12 Akim Demaille <akim@epita.fr>
7390
7391 * src/parse-gram.y (version_check): Exit 63 to please missing
7392 (stands for "version mismatch).

7402 that xlc complains about.
7403 * src/scan-skel.l (skel_wrap): Likewise.
7404 * data/c.m4 (b4_c_function_def): Look at __STDC_VERSION__ as well
7405 as __STDC__.
7406 * data/yacc.c (YYMODERN_C): New macro, which also looks at
7407 __STDC_VERSION__. Use it everywhere instead of looking at
7408 __STDC__ and __cplusplus.
7409
7410 2005-10-10 Akim Demaille <akim@epita.fr>
7411
7412 * examples/calc++/test: Be quiet unless VERBOSE.
7413
7414 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
7415

7417 Use YYUSE instead of casting to void.
7418 * data/glr.c (YYUSE): New macro.
7419 (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
7420 Use it instead of rolling our own.

7422 (YYCHK1):
7423 Use /*CONSTCOND*/ to suppress lint warnings.
7424 * data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
7425 (YY_STACK_PRINT): Use 'false' not '0'.

7430 (YYDPRINTF, YY_SYMBOL_PRINT, YY_STACK_PRINT, YY_REDUCE_PRINT):
7431 (yyerrorlab): Use /*CONSTCOND*/ to suppress lint warnings.
7432
7433
7434 * data/m4sugar/m4sugar.m4 (_m4_map): New macro.

7436
7437 2005-10-04 Paul Eggert <eggert@cs.ucla.edu>
7438
7439 Undo the parts of the unlocked-I/O change that substituted
7440 putc or puts for printf. This might hurt performance a bit,
7441 but some people prefer the printf style.
7442 * data/c.m4 (yysymprint): Prefer printf to puts and putc.
7443 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): Remove.
7444 All uses replaced by YYFPRINTF and YYDPRINTF.

7457 * src/state.c (state_rule_look_ahead_tokens_print): Likewise.
7458 * src/system.h: Include unlocked-io.h rathe than stdio.h.
7459
7460 * data/glr.c (yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
7461 Use assignments rather than casts-to-void to suppress
7462 unused-variable warnings. This pacifies 'lint'.
7463 * data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
7464 unused-variable warnings.
7465
7466 2005-10-03 Juan Manuel Guerrero <juan.guerrero@gmx.de>
7467
7468 * Makefile.am: DJGPP specific files added to EXTRA_DIST.
7469
7470 2005-10-02 Paul Eggert <eggert@cs.ucla.edu>
7471
7472 Use unlocked I/O for a minor performance improvement on hosts like
7473 GNU/Linux and Solaris that support unlocked I/O. The basic idea
7474 is to use the gnlib unlocked-io module, and to prefer putc and
7475 puts to printf when either will work (since the latter doesn't
7476 come in an unlocked flavor).
7477 * bootstrap (gnulib_modules): Add unlocked-io.
7478 * data/c.m4 (yysymprint): Prefer puts and putc to printf.
7479 * data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
7480 Prefer them to YYFPRINTF and YYDPRINTF if either will do,
7481 and similarly for puts and putc and printf.
7482 * data/yacc.c: Likewise.
7483 * lib/bitset.c (bitset_print): Likewise.
7484 * lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
7485 * lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
7486 to printf.
7487 * lib/lbitset.c (debug_lbitset): Likewise.

7545 for posix systems.
7546

7640 * bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
7641 it itself.
7642 * src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
7643 don't use alloca any more.
7644
7645 * data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
7646 __BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&
7647 defined _ALLOCA_H]: Don't include <stdlib.h>; not needed in this case.
7648 * tests/torture.at (Exploding the Stack Size with Alloca): Adjust
7649 to match yacc.c, to test more hosts.
7650
7651 2005-09-20 Paul Eggert <eggert@cs.ucla.edu>
7652
7653 * data/yacc.c (YYSIZE_T): Reindent to make it clearer. This
7654 doesn't affect behavior.

7656 Solaris, AIX, MSC.
7657 (_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
7658 This works a bit better with glibc, if user code has already included
7659 stdlib.h.
7660 * doc/bison.texinfo (Bison Parser): Document that users can't
7661 arbitrarily use malloc and free for other purposes. Document
7662 that <alloca.h> and <malloc.h> might be included.

7664 user must declare alloca.

7676 (YYSTACK_ALLOC_MAXIMUM): Use it.
7677 (yysyntax_error): New function.
7678 (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
7679 multiple syntax errors are reported, and alloca is being used.
7680 Instead, reallocate buffers twice as big each time, so that
7681 we waste at most half the allocated memory. Start with a small
7682 (128-byte) buffer that will suffice in most cases anyway.
7683 Use yysyntax_error to do most of the work.
7684
7685 * doc/bison.texinfo (Error Reporting, Table of Symbols):
7686 yynerrs is the number of errors reported, not the number of
7687 errors encountered.
7688
7689 * tests/glr-regression.at (Duplicated user destructor for lookahead):
7690 Mark it as expected to fail.
7691 Cast result of malloc; problem reported by twlevo@xs4all.nl.

7696
7697 Remove the traits, failed experiment.
7698 It never proved useful, and anyway because of the current
7699 definition, it was not possible to have several specialization of
7700 this traits, making it useless.
7701 * data/lalr1.cc (yy:traits): Remove.
7702 Inline its definitions in the parser class.
7703

7727 * data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
7728 (yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
7729 is not defined. This is an awful hack, but it's enough for now.
7730 All callers changed.
7731 * tests/glr-regression-at (make_value): Args are const pointers now,
7732 to avoid GCC warning.
7733 (Duplicated user destructor for lookahead): New test. Currently
7734 skipped. It fails on my host but I'm not sure it'll always fail.
7735

7737
7738 * src/symtab.h (struct symbol): Declare the printer and destructor

7757 (yyreport_syntax_error_): Remove, replaced by...
7758 (yysyntax_error_): this which returns a string and leaves to the
7759 caller the call to the users' error function.
7760 (yylooka_, yyilooka_, yylval, yylloc, yyerror_range_, yyval, yyloc):
7761 Move from members of the parser object...
7762 (yylooka, yyilooka, yylval, yylloc, yyerror_range, yyval, yyloc):

7787 do anything if $@ exists. This reverts part of the 2005-07-07
7788 patch.
7789
7790 2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
7791
7792 * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it
7793 contains obsolete information and isn't worth distributing as a
7794 separate file anyway.

7918 "make check" doesn't finish with "All 1 tests passed".
7919
7920 * tests/regression.at (Token definitions): Don't rely on
7921 AT_PARSER_CHECK for data that contains backslashes. It currently
7922 uses 'echo', and 'echo' isn't portable if its argument contains
7923 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
7924 that the byte '\0xff' is not printable in the C locale; it is,
7925 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
7926 not printable, so use '\0x81' to test.
7927
7928 * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
7929 version of GCC, since the macro is used with non-GCC compilers.
7930
7931 Fix core dump reported by Pablo De Napoli in
7932 <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
7933 * tests/regression.at (Invalid inputs with {}): New test.
7934 * src/parse-gram.y (token_name): Translate type before using
7935 it as an index.
7936
7937 * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
7938 the user's name space. All uses changed to __attribute__
7939 ((__unused__)).
7940 (yyFail, yyMemoryExhausted, yyreportAmbiguity):
7941 Add __attribute__ ((__noreturn__)).
7942
7943 * etc/clcommit: Remove. We weren't using it, and it failed
7944 "make maintainer-distcheck".
7945 * Makefile.maint: Merge from coreutils.
7946 (CVS_LIST, CVS_LIST_EXCEPT): New macros.
7947 (syntax-check-rules): Change list of rules as described below.
7948 (sc_cast_of_alloca_return_value, sc_dd_max_sym_length):
7949 (sc_file_system, sc_obsolete_symbols, sc_prohibit_atoi_atof):
7950 (sc_prohibit_jm_in_m4, sc_root_tests, sc_tight_scope):

7953 (sc_cast_of_argument_to_free, sc_cast_of_x_alloc_return_value):
7954 (sc_space_tab, sc_error_exit_success, sc_changelog):
7955 (sc_system_h_headers, sc_sun_os_names, sc_unmarked_diagnostics):
7956 (makefile-check, po-check, author_mark_check):
7957 (makefile_path_separator_check, copyright-check):
7958 Use grep -n, to make it easier to find violations.
7959 Use CVS_LIST and CVS_LIST_EXCEPT.
7960 (header_regexp, h_re): Remove.
7961 (dd_c): New macro.
7962 (sc_dd_max_sym_length, .re-list, news-date-check): New rules.
7963 (my-distcheck): Use more-modern GCC flags.
7964 (signatures, %.asc): Remove.
7965 (rel-files, announcement): Remove signatures.
7966 Restore old updating code, even though we don't use it, so
7967 that we're the same as coreutils.
7968 (alpha, beta, major): Depend on news-date-check.
7969 Make the upload commands.
7970
7971 * data/c.m4, data/lalr1.cc, data/yacc.c: Normalize white space.
7972 * lib/abitset.h, lib/bbitset.h, lib/bitset.h: Likewise.
7973 * lib/bitset_stats.c, lib/ebitset.h, lib/lbitset.c: Likewise.
7974 * lib/libitset.h, lib/timevar.c, lib/vbitset.h: Likewise.

7977 * src/vcg_defaults.h, tests/cxx-type.at, tests/existing.at: Likewise.
7978 * tests/sets.at: Likewise.
7979
7980 * data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
7981 we comment out the Autoconf version number.
7982 * doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as
7983 it's error-prone and "make maintainer-distcheck" rejects it.
7984
7985 * lib/subpipe.c: Include <fcntl.h> without checking for HAVE_FCNTL_H.
7986 Indent calls to "error" to pacify "make maintainer-distcheck",
7987 when the calls are not intended to be translated.
7988 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't check for fcntl.h.
7989
7990 * src/Makefile.am (DEFS): Use +=, to pacify
7991 "make maintainer-distcheck".
7992 (bison_SOURCES): Add scan-skel.h.
7993 (sc_tight_scope): New rule, from coreutils.
7994
7995 * src/files.c (src_extension, header_extension):
7996 Now static, not extern.
7997 * src/getargs.c (short_options): Likewise.
7998 * src/muscle_tab.c (muscle_table): Likewise.
7999 * src/parse-gram.y (current_class, current_type, current_prec):
8000 Likewise.
8001 * src/reader.c (grammar_end, previous_rule_end): Likewise.
8002 * src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
8003 * src/main.c (main): Cast bindtextdomain and textdomain calls to
8004 void, to avoid warning when NLS is disabled.
8005 * src/output.c: Include scan-skel.h.
8006 (scan_skel): Remove decl, since scan-skel.h does this.
8007 (output_skeleton):
8008 Indent calls to "error" to pacify "make maintainer-distcheck".
8009 * src/print_graph.c: Don't include <obstack.h>, as system.h does this.
8010 * src/reader.h (gram_end, gram_lineno): New decls to pacify
8011 "make maintainer-distcheck".
8012 * src/scan-skel.l (skel_lex, skel_get_lineno, skel_get_in):
8013 (skel_get_out, skel_get_leng, skel_get_text, skel_set_lineno):
8014 (skel_set_in, skel_set_out, skel_get_debug, skel_set_debug):
8015 (skel_lex_destroy, scan_skel): Move these decls to...
8016 * src/scan-skel.h: New file.
8017 * src/uniqstr.c (uniqstr_assert):
8018 Indent calls to "error" to pacify "make maintainer-distcheck".
8019
8020 * tests/Makefile.am ($(srcdir)/package.m4): Use $(VAR),
8021 not @VAR@.
8022
8023 * tests/torture.at: Revamp to avoid misuse of atoi that
8024 "make maintainer-distcheck" complained about.
8025
8026 * examples/extexi (message): Don't print a message more than once,
8027 and omit line-number decoration that makes Emacs compile think
8028 that informative messages are worth worrying about.
8029
8030 2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
8031
8032 * configure.ac: Update version number.
8033
8034 * Makefile.am (SUBDIRS): Add examples; somehow this got removed
8035 accidentally.
8036 * examples/calc++/calc++-parser.yy: Remove from CVS, as it's
8037 autogenerated by the maintainer.
8038 * examples/calc++/.cvsignore: Add *.yy.
8039
8040 * lib/bitset.c (bitset_alloc): Don't cast xcalloc result.
8041 * lib/bitset_stats.c (bitset_stats_init): Likewise.
8042 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8043
8044 * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
8045
8046 * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
8047 from maintainer-distcheck about casting the argument of 'free'.
8048
8049 * NEWS: Mention recent yytname changes.
8050 * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
8051
8052 * bootstrap: For translations that have not yet been upgraded to
8053 the new runtime-po domain, prime the pump by extracting the
8054 relevant strings from the obsolete translations. This code can be
8055 removed once the bison-runtime domain has been translated by each
8056 team.
8057
8058 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
8059 now that token names are already quoted.
8060
8061 Fix problem reported by Anthony Heading.
8062 * data/glr.c (YYTOKEN_TABLE): New macro.
8063 (yytname): Define if YYTOKEN_TABLE.
8064 * data/yacc.c (YYTOKEN_TABLE, yytname): Likewise.
8065 * data/lalr1.cc (YYTOKEN_TABLE, yytname_): Likewise.
8066 (YYERROR_VERBOSE): Define the same way the other skeletons do.
8067 * src/output.c (prepare_symbols): Output token_table_flag.
8068
8069 2005-07-21 Paul Eggert <eggert@cs.ucla.edu>
8070
8071 * data/glr.c (yyinitGLRStack, yyreturn): Don't call malloc
8072 again if the first call fails.
8073
8074 * data/glr.c (yytnamerr): New function.
8075 (yyreportSyntaxError): Use it to dequote most string literals.
8076 * data/lalr1.c (yytname_): Renamed from yyname_, for compatibility
8077 with other skeletons. All uses changed.
8078 (yytnameerr_): New function.
8079 (yyreport_syntax_error): Use it to dequote most string literals.
8080 * data/yacc.c (yytnamerr): New function.
8081 (yyerrlab): Use it to decode most string literals.
8082 * doc/bison.texinfo (Decl Summary, Calling Convention):
8083 Clarify quoting convention of yytname.
8084 * src/output.c (prepare_symbols): Quote all names. This undoes
8085 the 2005-04-17 change, which is now accomplished (mostly) via
8086 changes in the parsers as described above.
8087 * tests/regression.at (Token definitions, Web2c Actions):
8088 Undo most 2005-04-17 change here, too.
8089
8090 2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
8091
8092 Fix more problems reported by twlevo@xs4all.nl.
8093 * tests/cxx-type.at: Don't pipe output of ./types through sed to
8094 remove trailing spaces. This loses the exit status of ./types,
8095 and isn't needed since ./types shouldn't be emitting trailing
8096 spaces.
8097 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
8098 as the stack isn't valid in that case.
8099
8100 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
8101 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
8102 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
8103 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
8104 is used.
8105 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):
8106 (skel_get_leng, skel_get_text, skel_set_lineno, skel_set_in):
8107 (skel_set_out, skel_get_debug, skel_set_debug, skel_lex_destroy):
8108 Likewise.
8109
8110 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
8111 overly-picky compilers that reject 'char *foo = "bar";'.
8112
8113 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
8114 to FILE * parameter, not to stderr. This fixes a typo introduced
8115 in the 2005-07-12 change.
8116
8117 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
8118 warnings from GCC 4.
8119
8120 * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):
8121 (yyglrShiftDefer, yysplitStack):
8122 Remove unused parameters b4_pure_formals. All uses changed.
8123 (yyglrShift): Remove unused parameters b4_user_formals.
8124 All uses changed.
8125 (yyglrReduce): Removed unused parameter yylocp. All uses changed.
8126
8127 2005-07-18 Paul Eggert <eggert@cs.ucla.edu>
8128
8129 Destructor cleanups and regularization among the three skeletons.
8130 * NEWS: Document the behavior changes.
8131 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
8132 stack before failing, as the cleanup code will do it for us now.
8133 * data/lalr1.cc (yyerrlab): Likewise.
8134 * data/glr.c (yyparse): Pop everything off the stack before
8135 freeing it, so that destructors get called properly.
8136 * data/lalr1.cc (yyreturn): Likewise.
8137 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
8138 This is more consistent.
8139 * doc/bison.texinfo (Destructor Decl): Mention more reasons
8140 why destructors might be called. 1.875 -> 2.1.
8141 (Destructor Decl, Decl Summary, Table of Symbols):
8142 Some English-language cleanups for %destructor.
8143 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
8144 Add output line for destructor of start symbol.
8145 * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
8146 because of that same extra output line.
8147
8148 * NEWS: Document minor wording changes in diagnostics of
8149 Bison-generated parsers.
8150 * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
8151 Remove unused formals. All uses changed.
8152 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
8153 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
8154 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
8155 Rename yyoverflowab to yyexhaustedlab.
8156 When memory exhaustion occurs during syntax-error reporting,
8157 report it separately rather than in a single diagnostic; this
8158 eases translation.
8159 * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
8160 (Memory Exhausted): Renamed from Parser Stack Overflow.
8161 Revamp wording slightly to prefer "memory exhaustion".
8162 * tests/actions.at: "parser stack overflow" -> "memory exhausted".
8163
8164 * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
8165
8166 Add i18n support to the GLR skeleton. Partially fix the C++
8167 skeleton; a C++ expert needs to finish this. Remove debugging
8168 msgids; there's little point to having them translated, since they
8169 can be understood only by someone who can read the
8170 (English-language) source code.
8171
8172 Generate runtime-po/bison-runtime.pot automatically, so that we
8173 don't have to worry about garbage getting in that file. We'll
8174 make sure after the next official release that old msgids don't
8175 get lost. See
8176 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
8177
8178 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
8179 Now auto-generated.
8180 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
8181 Fix typos in explanations of the runtime file.
8182 * bootstrap: Change gettext keyword from YYI18N to YY_.
8183 Use standard Makefile.in.in in runtime-po, since we'll arrange
8184 for backward-compatible bison-runtime.po files in a different way.
8185 * data/glr.c (YY_): New macro, from yacc.c.
8186 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
8187 Translate messages intended for users.
8188 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
8189 the wording in the other skeletons. We don't know that the memory
8190 is virtual.
8191 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
8192 Use same method that yacc.c uses.
8193 Don't translate debugging messages.
8194 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
8195 it doesn't work (yet), and requires C++ expertise to fix.
8196 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
8197 Move defn to a more logical place, to be consistent with other
8198 skeletons.
8199 Don't translate debugging messages.
8200 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
8201 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
8202 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
8203 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
8204
8205 Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
8206 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
8207 void, not int.
8208 * tests/glr-regression.at (Badly Collapsed GLR States):
8209 Likewise.
8210 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8211 yylex should return 0 at EOF rather than aborting.
8212
8213 Improve tests for stack overflow in GLR parser.
8214 Problem reported by twlevo@xs4all.nl.
8215 * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
8216 All uses removed.
8217 (yyStackOverflow): Just longjmp, but with value 2 so that caller
8218 can handle the problem.
8219 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
8220 (yyparse): New local variable yyresult to record the result.
8221 Use result of setjmp to set it, rather than storing itinto
8222 struct.
8223 (yyDone): Remove label.
8224 (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
8225 to mimic yacc.c. Do not discard lookahead if it's EOF (possible
8226 if YYABORT is used).
8227 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
8228 yyparse status; put status > 1 into diagnostic.
8229 Check that status==2 works.
8230 * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
8231 Use exit status 3 for failure to open (which shouldn't happen).
8232
8233 2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
8234
8235 * tests/conflicts.at (%nonassoc and eof): Don't exit with status
8236 1 on syntax error; just let yyparse do its thing.
8237 * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
8238 * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
8239 (Exploding the Stack Size with Alloca):
8240 (Exploding the Stack Size with Malloc):
8241 Expect exit status 2, not 1, since the parser is supposed to blow
8242 its stack. Problem reported by twlevo@xs4all.nl.
8243
8244 * data/glr.c (yyparse): Don't assume that the initial calls
8245 to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
8246 Print a stack-overflow message and fail instead.
8247 Initialize the line-number information before creating the stack,
8248 so that the stack-overflow message can report line zero safely.
8249
8250 2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
8251
8252 Fix problems reported by twlevo@xs4all.nl.
8253 * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
8254 (yyuserMerge): Provide a default case if b4_mergers is empty.
8255 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
8256 * tests/glr-regression.at
8257 (Improper handling of embedded actions and dollar(-N) in GLR parsers):
8258 Add casts to pacify C++ compilers.
8259 * tests/glr-regression.at (Improper merging of GLR delayed action
8260 sets): Declare yylex before using it.
8261 * tests/Makefile.am (maintainer-check-g++): Fix a stray
8262 $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
8263 test for valgrind; valgrind is independent of g++.
8264 (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
8265 for compatibility with POSIX 1003.1-2001 (if running coreutils).
8266 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
8267 Use a destructor, so that we can expand the stack. Change
8268 YYSTYPE to char * so that we can free it. Cast result of malloc.
8269
8270 2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8271
8272 * data/glr.c (yyuserAction): Fix uninitialized variable that caused
8273 a valgrind failure. Problem reported by twlevo@xs4all.nl.
8274
8275 2005-07-13 Paul Eggert <eggert@cs.ucla.edu>
8276
8277 * PACKAGING: New file, suggested by Bruno Haible and taken from
8278 similar wording in gettext's PACKAGING file.
8279 * NEWS: Mention PACKAGING.
8280 * Makefile.am (EXTRA_DIST): Add PACKAGING.
8281
8282 2005-07-12 Paul Eggert <eggert@cs.ucla.edu>
8283
8284 * NEWS: Document recent i18n improvements.
8285 * bootstrap: Get runtime translations into runtime-po.
8286 Create runtime-po files automatically, if possible.
8287 * configure.ac: Invoke BISON_I18N, so that we eat our own dog food.
8288 * data/yacc.c: Rewrite inclusion of <libintl.h> so that ENABLE_NLS
8289 does not infringe on the user's name space.
8290 (YYENABLE_NLS): Renamed from ENABLE_BISON_NLS.
8291 * doc/bison.texinfo (Internationalization): Revamp the English
8292 and Texinfo syntax a bit, to try to make it clearer.
8293 (Bison Options, Option Cross Key): Mention --print-localedir.
8294 * m4/bison-i18n.m4 (BISON_I18N): Rename ENABLE_BISON_NLS to
8295 YYENABLE_NLS. Quote a bit more.
8296 * runtime-po/.cvsignore: New file.
8297 * runtime-po/Makefile.in.in (mostlyclean): Remove *.old.pot.
8298 * runtime-po/Rules-quot: Remove; now created by bootstrap.
8299 * runtime-po/quot.sed: Likewise.
8300 * runtime-po/boldquot.sed: Likewise.
8301 * runtime-po/en@quot.header: Likewise.
8302 * runtime-po/en@boldquot.header: Likewise.
8303 * runtime-po/insert-header.sin: Likewise.
8304 * runtime-po/remove-potcdate.sin: Likewise.
8305 * runtime-po/Makevars: Likewise.
8306 * runtime-po/LINGUAS: Likewise.
8307 * runtime-po/de.po: Likewise; we will rely on the translation project
8308 to maintain this, so "bootstrap" should get it.
8309 * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
8310 its value.
8311 * src/main.c (main): Bind the bison-runtime domain, too.
8312
8313 2005-07-12 Bruno Haible <bruno@clisp.org>
8314
8315 * data/yacc.c: Include <libintl.h> when NLS is enabled.
8316 (YYI18N): Renamed from _. Use dgettext when NLS is enabled.
8317 * po/POTFILES.in: Remove autogenerated file src/parse-gram.c.
8318 * runtime-po: New directory.
8319 * runtime-po/Makefile.in.in: New file, copied from po/, with modified
8320 $(DOMAIN).pot-update rule, so that old messages are never dropped.
8321 * runtime-po/Rules-quot: New file, copied from po/.
8322 * runtime-po/quot.sed: Likewise.
8323 * runtime-po/boldquot.sed: Likewise.
8324 * runtime-po/en@quot.header: Likewise.
8325 * runtime-po/en@boldquot.header: Likewise.
8326 * runtime-po/insert-header.sin: Likewise.
8327 * runtime-po/remove-potcdate.sin: Likewise.
8328 * runtime-po/Makevars: New file.
8329 * runtime-po/POTFILES.in: New file.
8330 * runtime-po/LINGUAS: New file.
8331 * runtime-po/bison-runtime.pot: New file.
8332 * runtime-po/de.po: New file.
8333 * m4/bison.m4: New file.
8334 * Makefile.am (SUBDIRS): Add runtime-po.
8335 (aclocaldir, aclocal_DATA): New variables.
8336 * configure.ac: Add AC_CONFIG_FILES of runtime-po/Makefile.in.
8337 Define aclocaldir.
8338 * src/getargs.c (usage): Document --print-localedir option.
8339 (PRINT_LOCALEDIR_OPTION): New enum item.
8340 (long_options): Add --print-localedir option.
8341 (getargs): Handle --print-localedir option.
8342 * doc/bison.texinfo (Bison Parser): Remove paragraph about _().
8343 (Internationalization): New section.
8344
8345 2005-07-12 Akim Demaille <akim@epita.fr>
8346
8347 * src/symtab.h, src/symtab.c (symbol_print): Swap the arguments,
8348 for consistency with the rest of the code.
8349 * src/symlist.h, src/symlist.c (symbol_list_print): Ditto.
8350 Add separators.
8351
8352 2005-07-12 Akim Demaille <akim@epita.fr>
8353
8354 * src/parse-gram.y: Use %printer instead of YYPRINT.
8355
8356 2005-07-12 Akim Demaille <akim@epita.fr>
8357
8358 * src/symtab.h, src/symtab.c (symbol_print): New.
8359 * src/symlist.h, src/symlist.c (symbol_list_print): New.
8360 * src/symlist.c (symbol_list_n_type_name_get): Report the culprit.
8361
8362 2005-07-12 Akim Demaille <akim@epita.fr>
8363
8364 * data/glr.c (b4_syncline): Fix (swap) the definitions of
8365 b4_at_dollar and b4_dollar_dollar.
8366
8367 2005-07-11 Paul Eggert <eggert@cs.ucla.edu>
8368
8369 * doc/bison.texinfo (Mystery Conflicts): Add reference to DeRemer
8370 and Pennello's paper.
8371
8372 2005-07-09 Paul Eggert <eggert@cs.ucla.edu>
8373
8374 * data/yacc.c (yyparse): Undo previous patch. Instead,
8375 set yylsp[0] and yyvsp[0] only if the initial action
8376 sets yylloc and yylval, respectively.
8377
8378 * data/yacc.c (yyparse): In the initial action, set
8379 yylsp[0] and yyvsp[0] rather than yylloc and yylval.
8380 This avoids the use of undefined variables if the initial
8381 action does not set yylloc and/or yylval.
8382
8383 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
8384
8385 * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
8386 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
8387 Remove from CVS. These files are automatically generated.
8388 * examples/extexi: Clarify that this file is now part of Bison,
8389 not GNU M4, and that it works with any POSIX-compatible Awk.
8390 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
8391 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
8392 so that we also get calc++-parser.yy. Geneate it.
8393 Use $(AWK), not gawk, since any conforming Awk will do.
8394 Put comment before action, since older 'make' can't handle comment
8395 in action.
8396 $(BUILT_SOURCES): List all built sources, not just some of them.
8397 $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
8398 $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
8399 $($(calc_sources_generated)): Remove unnecessary test for existence
8400 of target. (This had a shell syntax error anyway; a stray "x".)
8401 (calc_extracted): List $(srcdir)/calc++-parser.yy, not
8402 calc++-parser.yy.
8403 * examples/.cvsignore, examples/calc++/.cvsignore: New files.
8404
8405 * bootstrap (gnulib_modules): Add gettext, now that it's no longer
8406 implied by the other modules.
8407
8408 2005-07-06 Akim Demaille <akim@epita.fr>
8409
8410 Bind examples/calc++ to the package.
8411 * examples/calc++/Makefile: Remove, replaced by...
8412 * examples/calc++/Makefile.am: ... this new file.
8413 * examples/calc++/test: Remove input.
8414 * examples/calc++/compile: Remove.
8415 * examples/Makefile.am: New.
8416 * configure.ac, Makefile.am: Adjust.
8417 * doc/Makefile.am (clean-local): New, for more recent texi2dvis.
8418
8419 2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
8420
8421 * data/glr.c (yyFail): Drastically simplify; since the format argument
8422 never had any % directives, we can simply pass it to yyerror.
8423 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
8424 be modified later, as that is the usual style in glr.c.
8425 Problems reported by Paul Hilfinger.
8426
8427 Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
8428 and size overflow errors.
8429 * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
8430 in case the user prolog sets feature-test macros like _GNU_SOURCE.
8431 (YYSIZEMAX): New macro.
8432 (yystpcpy): New function, taken from yacc.c.
8433 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
8434 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
8435 so that we don't have to maintain their signatures.
8436 (yyFail): Check for buffer overflow, by using vsnprintf rather
8437 than vsprintf. Allocate a bigger buffer if possible.
8438 Report an error if buffer allocation fails.
8439 (yyStackOverflow): New function.
8440 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
8441 the initialization was successful. It might fail if storage was
8442 exhausted.
8443 (yyexpandGLRStack): Add more checks for storage allocation failure.
8444 Use yyStackOverflow to report failures.
8445 (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
8446 (yysplitStack, yyprocessOneStack, yyparse, yypstack):
8447 Don't assume stack number fits in int.
8448 (yysplitStack): Check for storage allocation failure.
8449 (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
8450 can print diagnostics on storage allocation failure. All callers
8451 changed.
8452 (yyresolveValue): Use yybool for boolean.
8453 (yyreportSyntaxError): Check for size-calculation overflow.
8454 This code is taken from yacc.c.
8455 (yyparse): Check for storage allocation errors when allocating
8456 the initial stack.
8457
8458 2005-07-05 Akim Demaille <akim@epita.fr>
8459
8460 Extract calc++ from the documentation.
8461 * doc/bison.texinfo (Calc++): Add the extraction marks.
8462 * examples/extexi: New, from the aborted GNU Programming 2E.
8463 Separate the different paragraph of a file with empty lines.
8464 * examples/Makefile: Use it to extract the whole calc++ example.
8465
8466 2005-06-24 Akim Demaille <akim@epita.fr>
8467
8468 * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
8469 class typedefs.
8470
8471 2005-06-22 Akim Demaille <akim@epita.fr>
8472
8473 * doc/bison.texinfo (C++ Language Interface): First stab.
8474 (C++ Parsers): Remove.
8475
8476 2005-06-22 Akim Demaille <akim@epita.fr>
8477
8478 * data/lalr1.cc (yylex_): Honor %lex-param.
8479
8480 2005-06-22 Akim Demaille <akim@epita.fr>
8481
8482 Start a set of simple examples.
8483 * examples/calc++/Makefile, examples/calc++/calc++-driver.cc,
8484 * examples/calc++/calc++-driver.hh,
8485 * examples/calc++/calc++-parser.yy,
8486 * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
8487 * examples/calc++/compile, examples/calc++/test: New.
8488
8489 2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
8490
8491 * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
8492 extern "C" {}. This fixes a problem reported by Paul Hilfinger,
8493 which stems from the 2005-05-27 patch.
8494
8495 2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
8496
8497 * data/glr.c: Modify treatment of unused parameters to permit use
8498 of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
8499
8500 2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
8501
8502 Fix infringement on user name space reported by Janos Zoltan Szabo.
8503 * data/yacc.c (yyparse): strlen -> yystrlen.
8504
8505 2005-05-30 Akim Demaille <akim@epita.fr>
8506
8507 * data/lalr1.cc (_): New.
8508 Translate the various messages.
8509
8510 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
8511
8512 Fix infringement on user name space reported by Bruno Haible.
8513 * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
8514 Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
8515 the user's name space.
8516 (alloca): Include <stdlib.h> to get it, if it's not built in.
8517 (YYMALLOC, YYFREE): Define only if needed.
8518 (malloc, free): Declare, but only if needed, as this infringes on
8519 the user name space.
8520
8521 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
8522
8523 Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
8524 * lib/bitset.c (bitset_print): Don't assume size_t can be printed
8525 with %d format.
8526 * lib/ebitset.c (min, max): Undef before defining.
8527 * lib/vbitset.c (min, max): Likewise.
8528 * lib/subpipe.c (create_subpipe): Save local variables in case
8529 vfork clobbers them.
8530
8531 2005-05-24 Bruno Haible <bruno@clisp.org>
8532
8533 * tests/synclines.at (AT_SYNCLINES_COMPILE): Add support for the
8534 error message syntax used by gcc-4.0.
8535
8536 2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
8537
8538 * README: Mention m4 1.4.3. Remove obsolete advice about
8539 Sun Forte Developer 6 update 2, VMS, and MS-DOS.
8540
8541 * bootstrap: Remove workaround for problem I encountered with
8542 gettext 0.14.1; it seems to be fixed now.
8543
8544 2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
8545
8546 * NEWS: Version 2.0a.
8547
8548 * src/files.c: Include "stdio-safer.h"; this fixes a typo in
8549 the previous change.
8550
8551 Various maintainer cleanups.
8552 * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
8553 conftest*, for benefit of CVS commands run at the same time as
8554 "configure". Add build-aux, since "bootstrap" now creates it and
8555 its subfiles.
8556 * Makefile.cfg (move_if_change): Remove.
8557 * Makefile.maint: Remove the update stuff; we now use "bootstrap".
8558 (ftp-gnu, www-gnu, move_if_change, local_updates, update):
8559 (po_repo, do-po-update, po-update, wget_files, get-targets):
8560 (config.guess-url_prefix, config.sub-url_prefix):
8561 (ansi2knr.c-url_prefix, texinfo.tex-url_prefix):
8562 (standards.texi-url_prefix, make-stds.texi-url_prefix, taget, url):
8563 ($(get-targets), cvs-files, automake_repo, wget-update, cvs-update):
8564 Remove.
8565 * configure.ac (AC_CONFIG_AUX_DIR): Change from config to build-aux;
8566 this is now the recommended name.
8567 * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
8568 depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
8569 ylwrap. These files now go into build-aux.
8570 * config/move-if-change: Remove.
8571 * config/prev-version.txt: Bump from 1.75 to 2.0.
8572
8573 * bootstrap: Add stdio-safer, unistd-safer modules.
8574 Remove m4/glibc2.m4 (introduced by latest gnulib, but
8575 we don't need it).
8576 * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
8577 fopen-safer.c, stdio-safer.h, unistd-safer.h.
8578 * lib/subpipe.c: Include "unistd-safer.h".
8579 (create_subpipe): Make sure all the newly-created
8580 file descriptors are > 2, so that diagnostics don't
8581 get sent down them (which might cause Bison to hang, in theory).
8582 * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
8583 * src/files.c (xfopen): Use fopen_safer, not fopen.
8584
8585 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
8586 yesterday's yacc.c fix.
8587
8588 2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
8589
8590 * data/glr.c, data/lalr1.cc: Update copyright date.
8591
8592 Fix a destructor bug reported by Wolfgang Spraul in
8593 <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
8594 * data/yacc.c (yyabortlab): Don't call destructor, and
8595 don't set yychar to EMPTY.
8596 (yyoverflowlab): Don't call destructor.
8597 (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
8598 * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
8599 since we no longer output the message "discarding lookahead token
8600 end of input ()".
8601
8602 2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
8603
8604 * data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
8605 fix a small glitch in debugging output.
8606 (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
8607 after YY_SYMBOL_PRINT where needed.
8608
8609 (struct yyGLRState): Add some comments.
8610 (struct yySemanticOption): Add some comments.
8611 (union yyGLRStackItem): Add comment.
8612
8613 (yymergeOptionSets): Correct this to properly perform the union,
8614 avoiding infinite reported by Michael Rosien.
8615 Update comment.
8616
8617 * tests/glr-regression.at: Add test for GLR merging error reported
8618 by M. Rosien.
8619

8657
8658 2005-05-11 Paul Eggert <eggert@cs.ucla.edu>
8659
8660 * tests/local.at (AT_COMPILE_CXX): Treat LDFLAGS like AT_COMPILE does.
8661 Problem reported by Ralf Menzel.
8662
8663 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
8664
8665 * tests/actions.at: Test that stack overflow invokes destructors.
8666 From Marcus Holland-Moritz.
8667 * data/yacc.c (yyerrlab): Move the code that destroys the stack
8668 from here....
8669 (yyreturn): to here. That way, destructors are called properly
8670 even if the stack overflows, or the user calls YYACCEPT or
8671 YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
8672 (yyoverflowlab): Destroy the lookahead.
8673
8674 2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
8675
8676 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
8677
8678 2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
8679
8680 * NEWS: Bison-generated C parsers no longer quote literal strings
8681 associated with tokens.
8682 * src/output.c (prepare_symbols): Don't escape strings,
8683 since users don't want to see C escapes.
8684 * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
8685 in diagnostics.
8686 * tests/input.at (Torturing the Scanner): Likewise.
8687 * tests/regression.at (Token definitions, Web2c Actions): Likewise.
8688
8689 2005-04-16 Paul Eggert <eggert@cs.ucla.edu>
8690
8691 * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if
8692 the data size is known to be too small and we can't increase it.
8693 This works around an HP-UX 11.00 glitch reported by Andrew Benham.
8694
8695 2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
8696
8697 * src/parse-gram.y: Include quotearg.h.
8698 (string_as_id): Quote $1 before using it as a key, since the
8699 lexer no longer quotes it for us.
8700 (string_content): Don't strip quotes, since lexer no longer
8701 quotes it for us.
8702 * src/scan-gram.l: Include quotearg.h.
8703 ("\""): Omit quote.
8704 ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
8705 a key, since the rest of the lexer doesn't quote it.
8706 * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
8707 * tests/regression.at (Token definitions): Check for backslashes
8708 in token strings.
8709
8710 * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
8711 (YYSIZE_T): Define to unsigned long int when using an older compiler.
8712 (yyparse): Revamp code to generate long syntax error message, to
8713 make it easier to translate, and to avoid problems with arithmetic
8714 overflow. Change "virtual memory" to "memory" in diagnostic, since
8715 we don't know whether the memory is virtual.

8717 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
8718
8719 * NEWS: Bison-generated C parsers now use the _ macro to
8720 translate strings.
8721 * data/yacc.c (_) [!defined _]: New macro.
8722 All English strings wrapped inside this macro.
8723 * doc/bison.texinfo (Bison Parser): Document _.
8724 * po/POTFILES.in: Include src/parse-gram.c, since it now
8725 includes translateable strings that parse-gram.y doesn't.
8726
8727 2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
8728
8729 * src/symtab.c (symbol_make_alias): Call symbol_type_set,
8730 reverting the 2004-10-11 change to this function.
8731 (symbol_check_alias_consistency): Don't call symbol_type_set
8732 if the type name is already correct.
8733 * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
8734
8735 2005-03-25 Paul Eggert <eggert@cs.ucla.edu>
8736
8737 * tests/regression.at (Token definitions): Don't use a token named
8738 c, as that generates a "#define c ..." that runs afoul of buggy
8739 stdlib.h that uses the identifier c as a member of struct
8740 drand48_data. Problem reported by Horst Wente.
8741
8742 2005-03-21 Paul Eggert <eggert@cs.ucla.edu>
8743
8744 * bootstrap: Change translation URL from
8745 http://www2.iro.umontreal.ca/~gnutra/po/maint/bison/ to
8746 http://www.iro.umontreal.ca/translation/maint/bison/ to avoid
8747 redirection glitches. Problem reported by twlevo@xs4all.nl.
8748
8749 2005-03-20 Paul Eggert <eggert@cs.ucla.edu>
8750
8751 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Don't put options
8752 after operands; POSIX says this isn't portable for the c99 command.
8753
8754 2005-03-18 Paul Eggert <eggert@cs.ucla.edu>
8755
8756 * tests/glr-regression.at (glr-regr2a.y): Try to dump core
8757 immediately if a data overrun has occurred; this may help us track
8758 down what may be a spurious failure on MacOS.
8759
8760 2005-03-17 Paul Eggert <eggert@cs.ucla.edu>
8761
8762 Respond to problems reported by twlevo@xs4all.nl.
8763
8764 * bootstrap: Use "trap - 0" rather than the unportable "trap 0".
8765
8766 * src/vcg.h: Comment fix.
8767 * src/vcg_defaults.h: Parenthesize macro bodies to make them safe.
8768 (G_CMAX): Change to -1 instead of INT_MAX.
8769
8770 * data/yacc.c (yyparse): Omit spaces before #line.
8771
8772 2005-03-15 Paul Eggert <eggert@cs.ucla.edu>
8773
8774 * src/tables.c (state_number_to_vector_number): Put it inside an
8775 "#if 0", since it's not currently used. Problem reported by
8776 Roland McGrath.
8777
8778 2005-03-06 Paul Eggert <eggert@cs.ucla.edu>
8779
8780 * src/output.c (escaped_output): Renamed from
8781 escaped_file_name_output, since we now use it for symbol tags as
8782 well. All uses changed.
8783 (symbol_destructors_output, symbol_printers_output):
8784 Escape symbol tags too.
8785 Problem reported by Matyas Forstner in
8786 <http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
8787
8788 * src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
8789 not needed.
8790 * src/output.c (user_actions_output, token_definitions_output,
8791 symbol_destructors_output, symbol_printers_output): Likewise.
8792 * src/reader.c (prologue_augment): Likewise.
8793 * src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
8794
8795 * src/vcg.c (output_edge): Don't quote linestyle arg.
8796 Problem reported by twlevo@xs4all.nl.
8797
8798 2005-02-28 Paul Eggert <eggert@cs.ucla.edu>
8799
8800 * doc/bison.texinfo (Semantic Tokens): Fix scoping problem in
8801 example, reported by Derek M Jones. Also, make the example even
8802 more outrageous, to better illustrate how bad the problem is.
8803
8804 2005-02-24 Paul Eggert <eggert@cs.ucla.edu>
8805
8806 * doc/bison.texinfo (Mfcalc Symtab): Correct the prototype for
8807 putsym. Typo reported by Sebastian Piping.
8808
8809 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
8810
8811 * doc/bison.texinfo (Language and Grammar): some -> same
8812 (Epilogue): int he -> in the
8813 Typos reported by Sebastian Piping via Justin Pence.
8814
8815 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
8816
8817 * tests/glr-regression.at (Improper handling of embedded actions
8818 and dollar(-N) in GLR parsers): Renamed from "Improper handling of
8819 embedded actions and $-N in GLR parsers", work around an Autoconf bug
8820 with dollar signs in test names.
8821 * tests/input.at (Invalid dollar-n): Renamed from "Invalid \$n",
8822 for a similar reason.
8823
8824 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
8825
8826 * src/vcg.c (output_graph): G_VIEW -> normal_view in case someone
8827 wants to redefine G_VIEW.
8828
8829 2005-01-27 Paul Eggert <eggert@cs.ucla.edu>
8830
8831 * src/vcg.c (get_view_str): Remove case for normal_view.
8832 Problem reported by twlevo@xs4all.nl.
8833
8834 2005-01-24 Paul Eggert <eggert@cs.ucla.edu>
8835
8836 * configure.ac (O0CFLAGS, O0CXXFLAGS): Fix quoting bug.
8837 Problem reported by twlevo@xs4all.nl.
8838
8839 * doc/bison.texinfo: Change @dircategory from "GNU programming
8840 tools" to "Software development". Requested by Richard Stallman
8841 via Karl Berry.
8842
8843 2005-01-23 Paul Eggert <eggert@cs.ucla.edu>
8844
8845 * tests/c++.at (AT_CHECK_DOXYGEN): Don't use options after operands.
8846 Problem reported by twlevo@xs4all.nl.
8847
8848 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
8849
8850 * data/yacc.c (YYCOPY, yystpcpy, yyparse): Remove "register"
8851 keyword; it's not needed with modern compilers, and it doesn't
8852 affect correctness with older compilers. Suggested by
8853 twlevo@xs4all.nl.
8854
8855 2005-01-17 Paul Eggert <eggert@cs.ucla.edu>
8856
8857 * data/glr.c (yyuserAction): Add "default: break;" case to pacify
8858 gcc -Wswitch-default.

8860 * data/yacc.c (yyparse): Likewise.
8861
8862 2005-01-12 Paul Eggert <eggert@cs.ucla.edu>
8863
8864 * src/system.h (OUTPUT_EXT, TAB_EXT): Define only if not defined
8865 already. Let config.h define any nonstandard values.
8866
8867 2005-01-10 Paul Eggert <eggert@cs.ucla.edu>
8868
8869 * tests/calc.at (_AT_DATA_CALC_Y): Use alarm (100), not alarm (10),
8870 for the benefit of slower hosts. Problem reported by
8871 Nelson H. F. Beebe.
8872
8873 2005-01-07 Paul Eggert <eggert@cs.ucla.edu>
8874
8875 * data/yacc.c (yyparse): Pacify non-GCC compilers about yyerrorlab
8876 being defined and not used.
8877 * data/lalr1.cc (yyparse): Likewise.
8878 Use "if (false)" rather than "if (0)".
8879
8880 2005-01-05 Paul Eggert <eggert@cs.ucla.edu>
8881
8882 * TODO: Mention that we should allow NUL bytes in tokens.
8883
8884 2005-01-02 Paul Eggert <eggert@cs.ucla.edu>
8885
8886 * src/scan-skel.l (<<EOF>>): Don't close standard output.
8887 Problem reported by Hans Aberg.
8888
8889 2005-01-01 Paul Eggert <eggert@cs.ucla.edu>
8890
8891 * src/getargs.c (version): Happy new year; update overall
8892 program copyright date from 2004 to 2005.
8893
8894 * src/scan-skel.l ("@output ".*\n): Don't close standard output.
8895 Problem reported by Hans Aberg.
8896 * tests/output.at (AT_CHECK_OUTPUT): New arg SHELLIO.
8897 (Output file names.): Add a test for the case when standard output
8898 is closed.
8899
8900 2004-12-26 Paul Eggert <eggert@cs.ucla.edu>
8901
8902 * doc/bison.texinfo (@copying): Update FDL version number to 1.2,
8903 to fix an oversight in the Bison 2.0 manual.
8904
8905 2004-12-25 Paul Eggert <eggert@cs.ucla.edu>
8906
8907 * NEWS: Version 2.0. Reformat the existing news items since
8908 1.875, so that related items are grouped together.
8909 * configure.ac (AC_INIT): Bump version to 2.0.
8910 * src/parse-gram.c, src/parse-gram.h: Regenerate with 2.0.
8911
8912 * tests/torture.at (Exploding the Stack Size with Alloca): Set
8913 YYSTACK_USE_ALLOCA to 1 if __GNUC__ or alloca are defined;
8914 otherwise, we're not testing alloca. Unfortunately there's no
8915 simple way to consult HAVE_ALLOCA here.
8916
8917 * data/lalr1.cc (yydestruct_): Pacify unused variable warning
8918 for yymsg, too.
8919
8920 * src/LR0.c (new_itemsets): Use memset rather than zeroing by
8921 hand. This avoids a warning about comparing int to size_t when
8922 GCC warnings are enabled.
8923
8924 2004-12-22 Paul Eggert <eggert@cs.ucla.edu>
8925
8926 * NEWS: Bison-generated parsers no longer default to using the
8927 alloca function (when available) to extend the parser stack, due
8928 to widespread problems in unchecked stack-overflow detection.
8929 * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's
8930 responsibility to set it to a positive value. This lets the user
8931 specify a value that is not a preprocessor constant.
8932 * data/yacc.c (YYMAXDEPTH): Likewise.
8933 (YYSTACK_ALLOC): Define only if YYSTACK_USE_ALLOCA is nonzero.
8934 * doc/bison.texinfo (Stack Overflow): YYMAXDEPTH no longer needs
8935 to be a compile-time constant. However, explain the constraints on it.
8936 Also, explain the constraints on YYINITDEPTH.
8937 (Table of Symbols): Explain that alloca is no longer the default.
8938 Explain the user's responsibility if they define YYSTACK_USE_ALLOCA
8939 to 1.
8940
8941 * doc/bison.texinfo (Location Default Action): Mention that n must
8942 be zero when k is zero. Suggested by Frank Heckenbach.
8943
8944 2004-12-22 Akim Demaille <akim@epita.fr>
8945
8946 * data/lalr1.cc (parser::token_number_type, parser::rhs_number_type)
8947 (parser::state_type, parser::semantic_type, parser::location_type):
8948 Private, not public.
8949 (parser::parse): Return ints, not bool.
8950 Returning a bool introduces a problem: 0 corresponds to false, and
8951 it seems weird to return false on success. Returning true changes
8952 the conventions for yyparse.
8953 Alternatively we could return void and send an exception.
8954 There is no clear consensus (yet?).
8955 (state_stack, semantic_stack, location_stack): Rename as...
8956 (state_stack_type, semantic_stack_type, location_stack_type): these.
8957 Private, not public.
8958 * tests/c++.at: New.
8959 * tests/testsuite.at, tests/Makefile.am: Adjust.
8960
8961 2004-12-21 Akim Demaille <akim@epita.fr>
8962
8963 * data/lalr1.cc (parser::parse): Return a bool instead of an int.
8964
8965 2004-12-21 Akim Demaille <akim@epita.fr>
8966
8967 Don't impose std::string for filenames.
8968
8969 * data/lalr1.cc (b4_filename_type): New.
8970 (position::filename): Use it.
8971 (parser.hh): Move the inclusion of stack.hh and location.hh below
8972 the user code, so that needed headers for the filename type can be
8973 included first.
8974 Forward declare them before the user code.
8975 * tests/Makefile.am (check-local, installcheck-local): Pass
8976 TESTSUITEFLAGS to the TESTSUITE.
8977
8978 2004-12-20 Akim Demaille <akim@epita.fr>
8979
8980 Use more STL like names: my_class instead of MyClass.
8981
8982 * data/lalr1.cc (LocationStack, LocationType, RhsNumberType)
8983 (SemanticStack, SemanticType, StateStack, StateType)
8984 (TokenNumberType, Stack, Slice, Traits, Parser::location)
8985 (Parser::value): Rename as...
8986 (location_stack, location_type, rhs_number_type, semantic_stack)
8987 (semantic_type, state_stack, state_type, token_number_type, stack)
8988 (slice, traits, parser::yylloc, parser::yylval): these.
8989
8990 * tests/calc.at, tests/regression.at, tests/actions.at: Adjust.
8991
8992 2004-12-19 Paul Eggert <eggert@cs.ucla.edu>
8993
8994 * data/glr.c (YYLLOC_DEFAULT): Use GNU spacing conventions.
8995 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
8996
8997 2004-12-17 Paul Eggert <eggert@cs.ucla.edu>
8998
8999 Remove uses of 'short int' and 'unsigned short int'. This raises
9000 some arbitrary limits. It uses more memory but nowadays that's
9001 not much of an issue.
9002
9003 This change does not affect the generated parsers; that's a different
9004 task, as some users will want to conserve memory there.
9005
9006 Ideally we should use size_t to represent all object counts, and
9007 something like ptrdiff_t to represent signed differences of object
9008 counts; but that will require more code-cleanup than I have the
9009 time to do right now.
9010
9011 * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
9012 Use size_t, not int or short int, to count objects.
9013 * src/closure.c (nritemset, closure): Likewise.
9014 * src/closure.h (nritemset, closure): Likewise.

9020 * src/tables.c (default_goto, goto_actions): Likewise.
9021
9022 * src/gram.h (rule_number, rule): Use int, not short int.
9023 * src/output.c (prepare_rules): Likewise.
9024 * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
9025 errs, reductions): Likewise.
9026 * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
9027 Likewise.
9028 * src/tables.c (vector_number, tally, action_number,
9029 ACTION_NUMBER_MINIMUM): Likewise.
9030 * src/output.c (muscle_insert_short_int_table): Remove.
9031
9032 2004-12-17 Akim Demaille <akim@epita.fr>
9033
9034 * data/lalr1.cc: Extensive Doxygenation.
9035 (error_): Rename as...
9036 (error): this, since it is visible to the user.
9037 Adjust callers.
9038 (Parser::message): Now an automatic variable from...
9039 (Parser::yyreport_syntax_error_): here.
9040 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust to
9041 Parser::error.
9042 * tests/input.at: Escape $.
9043
9044 2004-12-16 Paul Eggert <eggert@cs.ucla.edu>
9045
9046 * data/glr.c (b4_lhs_value, b4_rhs_value, b4_rhs-location):
9047 Parenthesize rhs to avoid obscure problems with mistakes like
9048 "foo$$bar = foo$1bar;". Problem reported by twlevo at xs4all.
9049 * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9050 b4_rhs_location): Likewise.
9051 * data/yacc.c (b4_lhs_value, b4_rhs_value, b4_lhs_location,
9052 b4_rhs_location): Likewise.
9053
9054 2004-12-16 Akim Demaille <akim@epita.fr>
9055
9056 * data/lalr1.cc (yyreport_syntax_error_): Catch up with glr.c and
9057 yacc.c: be sure to stay within yycheck_.
9058 * tests/actions.at: Re-enable C++ tests.
9059
9060 2004-12-16 Akim Demaille <akim@epita.fr>
9061
9062 * src/print_graph.c (print_graph): Remove layoutalgorithm uses for
9063 real.
9064
9065 2004-12-16 Akim Demaille <akim@epita.fr>
9066

9068
9069 * data/glr.c, data/yacc.c: Comment changes.
9070 * data/lalr1.cc (yylex): Use #define to select the name of yylex,
9071 so that one can refer to yylex in the parser file, and have it
9072 renamed, as is the case with other skeletons.
9073
9074 2004-12-16 Akim Demaille <akim@epita.fr>
9075
9076 Move lalr1.cc internals into yy*.

9096 2004-12-15 Paul Eggert <eggert@cs.ucla.edu>
9097
9098 Fix some problems reported by twlevo at xs4all.
9099 * src/symtab.c (symbol_new): Report an error if the input grammar
9100 contains too many symbols. This is better than calling abort() later.
9101 * src/vcg.h (enum layoutalgorithm): Remove. All uses removed.
9102 (struct node, struct graph):
9103 Rename member expand to stretch. All uses changed.
9104 (struct graph): Remove member layoutalgorithm. All uses removed.

9128
9129 Simplify the C++ parser constructor.
9130
9131 * data/lalr1.cc (debug_): Rename as...
9132 (yydebug_): so that the parser's internals are always in the yy*
9133 pseudo namespace.
9134 Adjust uses.
9135 (b4_parse_param_decl): Remove the leading comma as it is now only
9136 called as unique argument list.
9137 (Parser::Parser): Remove the constructor accepting a location and
9138 an initial debugging level.
9139 Remove from the other ctor the argument for the debugging level.
9140 (debug_level_type, debug_level, set_debug_level): New.
9141
9142 * tests/actions.at, tests/calc.at, tests/regression.at: Adjust
9143 constructor calls.
9144
9145 2004-12-15 Akim Demaille <akim@epita.fr>
9146
9147 Remove b4_root related material: failure experiment
9148 (which goal was to allow to derive from a class).
9149
9150 * data/lalr1.cc (b4_root, b4_param, b4_constructor): Remove
9151 definitions and uses.
9152
9153 2004-12-14 Paul Eggert <eggert@cs.ucla.edu>
9154
9155 * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
9156 not 2, since it's not portable to subtract 1 from the start of an
9157 array. The new item 0 is never set or used. All uses changed.
9158
9159 (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming
9160 the default definition of YYLLOC_DEFAULT. Problem reported
9161 by Frank Heckenbach.
9162
9163 2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
9164
9165 * data/glr.c (YYRHSLOC): Don't have two definitions, one for
9166 the normal case and one for the error case. Just use the
9167 first one uniformly. Problem reported by Frank Heckenbach.
9168 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
9169 use exactly the same macro in both places.
9170 (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
9171 so that the normal-case YYRHSLOC works for the error case too.
9172 All uses changed.
9173 * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
9174 (YYLLOC_DEFAULT): Use the same macro as glr.c.
9175 * doc/bison.texinfo (Location Default Action): Don't claim that
9176 we have an array of locations. Use the same macro for both glr
9177 and lalr parsers. Mention YYRHSLOC. Mention what happens when
9178 the index is 0.
9179
9180 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9181
9182 * HACKING: Update email addresses to send announcements to.
9183
9184 * configure.ac (AC_INIT): Bump version to 1.875f.
9185
9186 2004-12-10 Paul Eggert <eggert@cs.ucla.edu>
9187
9188 * NEWS: Version 1.875e.
9189 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875e.
9190
9191 * src/scan-skel.l: Include "complain.h", for "fatal".
9192
9193 * src/relation.h (relation_print, relation_digraph):
9194 Relation sizes are of type relation_node, not size_t (this is
9195 merely a doc fix, since the two types are equivalent).
9196 (relation_transpose): Relation sizes are of type relation_node,
9197 not int.
9198 * src/relation.c: Likewise.
9199 (top, infinity): Now of type relation_node, not int.
9200 (traverse, relation_transpose): Use relation_node, not int.
9201
9202 * data/glr.c (yyuserAction, yyrecoverSyntaxError): Mark args
9203 with ATTRIBUTE_UNUSED if they're not used, to avoid GCC warning.
9204 (yyparse): Remove unused local introduced in 2004-10-25 patch.
9205
9206 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
9207 specifying whether the test should be skipped. Use it tp
9208 specify that the [%defines %skeleton "lalr1.cc"] tests currently
9209 fail on some hosts, and should be skipped.
9210
9211 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
9212
9213 * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
9214 changed to use xcalloc, xnmalloc, xnrealloc, respectively,
9215 unless otherwise specified below.
9216
9217 * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,
9218 to allocate kernel_base, kernel_items, kernel_size, since
9219 they needn't be initialized to 0.
9220 (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
9221 * src/closure.c (new_closure): Likewise, for itemset.
9222 * src/derives.c (derives_compute): Likewise, for delts, derives, q.
9223 * src/lalr.c (set_goto_map): Likewise, for temp_map.
9224 (initialize_F): Likewise, for reads, edge, reads[i], includes[i].
9225 (build_relations): Likewise for edge, states1, includes.
9226 * src/nullable.c (nullable_compute): Likewise, for squeue, relts.
9227 * src/reader.c (packgram): Likewise, for ritem, rules.
9228 * src/reduce.c (nonterminals_reduce): Likewise for nontermmap.
9229 * src/relation.c (relation_digraph): Likewise for VERTICES.
9230 (relation_transpose): Likewise for new_R, end_R.
9231 * src/symtab.c (symbols_token_translations_init): Likewise for
9232 token_translations.
9233 * src/tables.c (save_row): Likewise for froms, tos, conflict_tos.
9234 (token_actions): Likewise for yydefact, actrow, conflrow,
9235 conflict_list.
9236 (save_column): Likewise for froms[symno], tos[symno].
9237 (goto_actions): Likewise for state_count.
9238 (pack_table): Likewise for base, pos, check.
9239 (tables_generate): Likewise for width.
9240
9241 * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
9242 for initial core. Just have a separate core, so we needn't worry
9243 about whether kernel_size and kernel_base are initialized.
9244
9245 * src/LR0.c (shift_symbol, redset, shiftset, kernel_base,
9246 kernel_size, kernel_items): Remove unnecessary initialization.
9247 * src/conflicts.c (conflicts): Likewise.
9248 * src/derives.c (derives): Likewise.
9249 * src/muscle_tablc (muscle_insert): Likewise.
9250 * src/relation.c (relation_digraph): Likewise.
9251 * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order,
9252 conflrow, conflict_table, conflict_list, table, check):
9253 Likewise.
9254
9255 * src/closure.c (new_closure): Arg is of type unsigned int, not int.
9256 This is because all callers pass unsigned int.
9257 * src/closure.h (new_closure): Likewise.
9258
9259 * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
9260 (build_relations): Initialize includes[i] in all cases.
9261 * src/reader.c (packgram): Always initialize rules[ruleno].prec
9262 and rules[ruleno].precsym. Initialize members in order.
9263 * src/relation.c (relation_transpose): Always initialize new_R[i]
9264 and end_R[i].
9265 * src/table.c (conflict_row): Initialize 0 at end of conflict_list.
9266
9267 * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
9268 conflict_list[0] was always 0, but now it isn't initialized.
9269
9270 * src/table.c (table_grow): When conflict_table grew, the grown
9271 area wasn't cleared. Fix this.
9272
9273 * lib/.cvsignore: Add strdup.c, strdup.h.
9274 * m4/.cvsignore: Add strdup.m4.
9275
9276 2004-12-07 Paul Eggert <eggert@cs.ucla.edu>
9277
9278 * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
9279 * src/lalr.c (set_goto_map): Don't allow ngotos to equal
9280 GOTO_NUMBER_MAXIMUM, since we occasionally compute
9281 ngotos + 1 without checking for overflow.
9282 (build_relations): Use END_NODE, not -1, to denote end of edges.
9283 * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
9284 build_relations): Use goto_number, not int, for goto numbers.
9285 * src/tables.c (save_column, default_goto): Likewise.
9286
9287 2004-11-23 Akim Demaille <akim@epita.fr>
9288
9289 * data/lalr1.cc (YYSTYPE): Define it as is done for C, instead
9290 of #defining from yystype.
9291 Don't typedef yystype, C++ does not need it.
9292 This lets it possible to forward declare it as union.
9293
9294 2004-11-23 Paul Eggert <eggert@cs.ucla.edu>
9295
9296 * bootstrap (gnulib_modules): Add extensions.
9297 Problem reported by Jim Meyering.
9298
9299 2004-11-22 Paul Eggert <eggert@cs.ucla.edu>
9300
9301 * src/LR0.c, src/closure.c, src/derives.c, src/gram.c,
9302 src/lalr.c, src/nullable.c, src/relation.c, src/scan-skel.l,
9303 src/system.h, src/tables.c: XFREE -> free, to accommodate
9304 recent change to gnulib xalloc.h.
9305 Problem reported by Jim Meyering.
9306
9307 2004-11-17 Akim Demaille <akim@epita.fr>
9308
9309 * data/lalr1.cc (symprint_): Use cdebug_ to avoid warnings.
9310
9311 2004-11-17 Akim Demaille <akim@epita.fr>,
9312 Alexandre Duret-Lutz <adl@gnu.org>
9313
9314 * data/lalr1.cc (Parser::yycdebug_): New, a pointer, to allow
9315 changes.
9316 (YYCDEBUG): Adjust.
9317 Use it instead of cdebug_.
9318 (Parser::debug_stream, Parser::set_debug_stream): New.
9319 (Parser::symprint_): Define cdebug_ for temporary backward
9320 compatibility.
9321 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use
9322 debug_stream ().
9323
9324 2004-11-17 Akim Demaille <akim@epita.fr>
9325
9326 * data/lalr1.cc (Parser:print_): Remove, use %printer instead.
9327 * tests/regression.at (_AT_DATA_DANCER_Y): Adjust.
9328 * tests/calc.at (_AT_DATA_CALC_Y): Ditto.
9329 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
9330
9331 2004-10-27 Paul Eggert <eggert@cs.ucla.edu>
9332
9333 * data/glr.c (yyloc_default): Remove; not used.
9334 Problem reported by Frank Heckenbach.
9335
9336 2004-10-25 Akim Demaille <akim@epita.fr>
9337
9338 * data/glr.c (YYRHSLOC): Move its definition next to its uses.
9339 Introduce another definition to address simple location arrays.
9340 (yyGLRStack): New member: yyerror_range.
9341 (yyrecoverSyntaxError, yyparse): Update it.
9342 (yyrecoverSyntaxError): Use it when shifting the error token to
9343 have an accurate range, equivalent to the one computed by both
9344 yacc.c and lalr1.cc.
9345 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
9346 that column numbers start at column 0, as per GNU Coding
9347 Standards, the others tests, and the doc.
9348 (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
9349 Adjust to the above change (first column is 0).
9350 And adjust the location of the "<error>", now covering the whole
9351 line.
9352
9353 2004-10-22 Akim Demaille <akim@epita.fr>
9354 and Paul Eggert <eggert@cs.ucla.edu>
9355
9356 Remove some arbitrary limits on goto numbers and relations.
9357 * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
9358 initial values, since they're never used.
9359 (set_goto_map): ngotos is now unsigned, so test for overflow
9360 by seeing whether it wraps around to zero.
9361 * src/lalr.h (goto_number): Now size_t, not short int.
9362 (GOTO_NUMBER_MAXIMUM): Remove.
9363 * src/relation.c (relation_print, traverse, relation_transpose):
9364 Check for END_NODE rather than looking at sign.
9365 * src/relation.h (END_NODE): New macro.
9366 (relation_node): Now size_t, not short int.
9367
9368 2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
9369
9370 * doc/bison.texinfo (Language and Grammar): In example, "int" is a
9371 keyword, not an identifier. Problem reported by Baron Schwartz in
9372 <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
9373
9374 2004-10-11 Akim Demaille <akim@epita.fr>
9375
9376 * src/symtab.c (symbol_check_alias_consistency): Also check
9377 type names, destructors, and printers.
9378 Reported by Alexandre Duret-Lutz.
9379 Recode the handling of associativity and precedence in terms
9380 of symbol_precedence_set.
9381 Accept no redeclaration at all, not even equal to the previous
9382 value.
9383 (redeclaration): New.
9384 Use it to factor redeclaration complaints.
9385 (symbol_make_alias): Don't set the type of the alias, let
9386 symbol_check_alias_consistency do it as for other features.
9387 * src/symtab.h (symbol): Add new member prec_location, and
9388 type_location.
9389 * src/symtab.c (symbol_precedence_set, symbol_type_set): Set them.
9390 * tests/input.at (Incompatible Aliases): New.
9391
9392 2004-10-09 Paul Eggert <eggert@cs.ucla.edu>
9393
9394 .cvsignore fixes to accommodate gnulib changes,
9395 and the practice of naming build directories "_build".
9396 * .cvsignore: Add "_*". Sort.
9397 * lib/.cvsignore: Add getopt_.h, xalloc-die.c.
9398 * m4/.cvsignore: Add "*_gl.m4".
9399
9400 2004-10-06 Akim Demaille <akim@epita.fr>
9401
9402 * src/parse-gram.y (add_param): Fix the truncation of trailing
9403 spaces.
9404
9405 2004-10-05 Akim Demaille <akim@epita.fr>
9406
9407 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
9408 whether the reducion was empty or not. This leaves room to
9409 improve the use of YYLLOC_DEFAULT in such a case.
9410 lalr1.cc is still experimental, so changing this is acceptable.
9411 And finally, there are probably not many users who changed the
9412 handling of locations in GLR, so changing is admissible too.
9413
9414 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
9415 empty reduction, set @$ to an empty location ending the previously
9416 stacked symbol.
9417 Adjust uses to make sure the code is triggered on empty
9418 reductions.
9419 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
9420 expected output: empty reductions have empty locations.
9421
9422 2004-09-29 Akim Demaille <akim@epita.fr>
9423
9424 * data/lalr1.cc: Move towards a more standard C++ coding style
9425 for templates: Class < T > -> Class<T>.
9426
9427 2004-09-29 Akim Demaille <akim@epita.fr>
9428
9429 * data/lalr1.cc: Reinstall the former ctor, for sake of
9430 compatibility, but warn it will be removed.
9431 Move towards a more standard C++ coding style (i.e., type *var ->
9432 type* var).
9433
9434 2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
9435
9436 * src/parse-gram.y (add_param): Rewrite to avoid strchr,
9437 since it's less likely to work if NULs are involved in the future.
9438
9439 2004-09-27 Akim Demaille <akim@epita.fr>
9440
9441 * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.
9442
9443 2004-09-27 Akim Demaille <akim@epita.fr>
9444
9445 * data/lalr1.cc (b4_parse_param_decl_1): New.
9446 (b4_parse_param_decl): Use it to have different names between attribute
9447 and argument names.
9448 (b4_cc_constructor_call): Likewise.
9449
9450 2004-09-24 Akim Demaille <akim@epita.fr>
9451
9452 * src/parse-gram.y (add_param): Strip the leading and trailing
9453 blanks from a formal argument declaration.
9454 (YY_LOCATION_PRINT): New.
9455
9456 2004-09-24 Akim Demaille <akim@epita.fr>
9457
9458 * data/c.m4 (b4_yysymprint_generate): Move the YYINPUT invocation
9459 after the location.
9460
9461 2004-09-24 Akim Demaille <akim@epita.fr>
9462
9463 * doc/bison.texinfo (Table of Symbols): Sort.
9464
9465 2004-09-21 Akim Demaille <akim@epita.fr>
9466
9467 * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
9468 the useless parentheses.
9469 Suggested by Paul Eggert.
9470
9471 2004-09-20 Akim Demaille <akim@epita.fr>
9472
9473 Let the initial-action act on the look-ahead, and use it for the
9474 "initial push" (corresponding to an hypothetical beginning-of-file).
9475 And let lalr1.cc honor %initial-action.
9476
9477 * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
9478 example.
9479 * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
9480 (Parser::Parser): Remove the ctor that used to initialize it.
9481 (Parser::parse): Like in the other skeletons, issue the "starting
9482 parse" message before any action.
9483 Honor %initial-action.
9484 Initialize the stacks with the lookahead.
9485 * data/yacc.c: Let $$ and @$ in %initial-action designate the
9486 look-ahead.
9487 Push them in the stacks.
9488 * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
9489
9490 2004-09-20 Akim Demaille <akim@epita.fr>
9491
9492 * doc/bison.texinfo (Initial Action Decl): New.
9493
9494 2004-09-20 Akim Demaille <akim@epita.fr>
9495
9496 * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
9497 clearer criterion to define it.
9498 (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
9499 When reducing on an empty RHS, use the latest stacked location as
9500 location.
9501 yylloc is not always available.
9502 * data/glr.c: Likewise.
9503 Also, honor initial-actions.
9504
9505 2004-09-20 Akim Demaille <akim@epita.fr>
9506
9507 * data/yacc.c (YY_LOCATION_PRINT): New.
9508 Define when we know YYLTYPE's structure, i.e., when the default
9509 YYLLOC_DEFAULT is used.
9510 * data/c.m4 (b4_yysymprint_generate): Use it.
9511 * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
9512 value of the result.
9513 (error_start_): Replace with...
9514 (error_range_): this location array.
9515 This allows to replace code relying on the implementation of
9516 locations by portable code.
9517 * data/yacc.c (yylerrsp): Replace with...
9518 (yyerror_range): this.
9519 Every time a token is popped, update yyerror_range[0], to have an
9520 accurate location for the error token.
9521 * data/glr.c (YY_LOCATION_PRINT): New.
9522 (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
9523 deference a pointer.
9524 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
9525 report the location in %printers.
9526
9527 * src/scan-skel.l: Instead of abort, report error messages to ease
9528 understanding skeleton scanning failures.
9529
9530 2004-09-16 Akim Demaille <akim@epita.fr>
9531
9532 * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
9533 (iterator, const_iterator): these, to be more in the C++ spirit.
9534 Also, return reverse iterators so that when displaying the stack
9535 we display its bottom first.
9536 (Parser::stack_print_, Parser::reduce_print_): Match the messages
9537 from yacc.c.
9538 We should probably use vector here though.
9539
9540 2004-09-16 Akim Demaille <akim@epita.fr>
9541
9542 Have more complete shift traces.
9543
9544 * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
9545 to report Shifts instead of ad hoc YYDPRINTF invocations,
9546 including for the error token.
9547 * data/lalr1.cc (symprint_): Output the location.
9548 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
9549 output the location within the %printer.
9550 Activate GLR tests, at least to make sure they compile properly.
9551 They still don't pass though.
9552 * tests/calc.at: Adjust expect verbose output, since now "Entering
9553 state..." is on a different line than the "Shifting" message.
9554
9555 2004-09-08 Akim Demaille <akim@epita.fr>
9556
9557 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
9558 Bison directive from the Bison file to the invocation of this
9559 macro, so that these directives are passed to
9560 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
9561 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
9562 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
9563 the extra Bison directives instead of the whole series.
9564 Change the grammar so that there are recoverable errors, and
9565 unrecoverable errors. Now we can have the parser give up before
9566 consuming the whole input. As a result we now can observe that
9567 the lookahead is freed when needed.
9568 Change the parser source to parse argv[1] instead of a hard coded
9569 string.
9570 Simplify yylex, and give a value and location to EOF.
9571 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
9572 passed directives already coded in the file.
9573 Add some tests to check the location of "error".
9574 For some tests, the C++ parser is correct, and not yacc.c.
9575 For other tests, they provide different, but unsatisfying, values,
9576 so keep the C++ value so that at least one parser is "correct"
9577 according to the test suite.
9578 (Actions after errors): Remove, this is subsumed by the
9579 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

9591 Call YY_SYMBOL_PRINT.
9592 Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
9593 * data/lalr1.cc (destruct_): Likewise.
9594 In addition, no longer depend on b4_yysymprint_generate and
9595 b4_yydestruct_generate to generate these functions, do it "by
9596 hand".
9597
9598 2004-09-03 Akim Demaille <akim@epita.fr>
9599
9600 * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
9601 invoked, yydestruct the lookahead.
9602 * tests/calc.at (Calculator $1): Update the expected lengths of
9603 traces: there is an added line for the discarded lookahead.
9604 * doc/bison.texinfo (Destructor Decl): Some rewording.
9605 Define "discarded" symbols.
9606
9607 2004-09-02 Akim Demaille <akim@epita.fr>
9608
9609 * data/lalr1.cc (translate_, destruct_): No reason to be static.

9622 2004-09-02 Akim Demaille <akim@epita.fr>
9623
9624 * data/lalr1.cc (b4_yysymprint_generate): New.
9625 (symprint_): New member function, defined when YYDEBUG.
9626 Use it consistently instead of token/nterm debugging output by
9627 hand.

9631 2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
9632
9633 * data/glr.c: Guard the declarations of yypstack and yypdumpstack

9643 Adjust to latest gnulib.
9644 * bootstrap (gnulib_modules): Add xalloc-die.
9645 Set LC_ALL=C so that file names sort consistently.
9646 Prefer the gnulib copies of gettext.m4, glibc21.m4,
9647 inttypes_h.m4, lib-ld.m4, lib-prefix.m4, po.m4, stdint_h.m4,
9648 uintmax_t.m4, ulonglong.m4.
9649 (intl_files_to_remove): Add gettext.m4, lib-ld.m4, lib-prefix.m4,
9650 po.m4 since we are now using _gl.m4 instead.
9651
9652 2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>
9653
9654 * src/scan-action.l: Remove. Scanning of semantic actions is
9655 handled in scan-gram.l.

9662 (equal_boundaries): Use UNIQSTR_EQ for comparison.
9663
9664 2004-07-22 Paul Eggert <eggert@cs.ucla.edu>
9665
9666 Fix bug with non-%union parsers that have printers or destructors,
9667 which led to a Bison core dump. Reported by Peter Fales in
9668 <http://lists.gnu.org/archive/html/bug-bison/2004-07/msg00014.html>.
9669
9670 * data/c.m4 (b4_symbol_actions): Don't assume %union was used.
9671 * data/lalr1.cc (yystype) [defined YYSTYPE]: Define to YYSTYPE,
9672 not to our own type.

9674 Don't assume %union.
9675 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR,
9676 AT_CHECK_PRINTER_AND_DESTRUCTOR): New argument
9677 UNION-FLAG. All callers changed.
9678 (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't assume %union.
9679 Use type char, not unsigned int, when declaring an array of char;
9680 this lets us remove a cast.
9681 (Printers and Destructors): Add non-%union test cases.
9682
9683 2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
9684
9685 * doc/bison.texinfo: Minor editorial changes, mostly to the new
9686 GLR writeups. E.g., avoid frenchspacing and the future tense,
9687 change "lookahead" to "look-ahead", and change "wrt" to "with
9688 respect to".
9689
9690 2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
9691
9692 * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):
9693 New sections, split off from the GLR Parsers section. Put the new
9694 Simple GLR Parser near the start of the GLR section, for clarity.
9695 Rewrite connective text.
9696
9697 2004-06-21 Frank Heckenbach <frank@g-n-u.de>

9702
9703 * NEWS, TODO, doc/bison.texinfo:
9704 Use "look-ahead" instead of "lookahead", to be consistent.

9706 while we're fixing "look-ahead".
9707 * src/conflicts.c (shift_set): Renamed from shiftset.

9733 (trivial change).
9734 * configure.ac (O0CXXFLAGS): New var.
9735 * tests/atlocal.in (CXXFLAGS): Use it.
9736

9754
9755 2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
9756
9757 Spent a few hours checking out which prerequisite versions the
9758 current sources actually require. I went all the way back to
9759 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
9760 a seemingly endless set of combinations of versions more recent
9761 than that. The bottom line is that the current sources require
9762 fairly recent versions of the build tools, and it'll be some work
9763 to change this.
9764 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
9765 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
9766 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
9767 Add comments explaining why those particular versions are
9768 currently needed.
9769
9770 * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
9771 in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
9772 <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
9773
9774 * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
9775 (it fails with a Autoconf-without-aclocal-m4 diagnostic).
9776
9777 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
9778
9779 * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
9780 0.11.5. Suggested by Bruno Haible.
9781 * bootstrap: Remove gettext version checking.
9782
9783 * doc/bison.texinfo (Decl Summary): Also mention that %union
9784 can depend on prerequisite types. Problem reported by Tim
9785 Van Holder.
9786
9787 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
9788
9789 * README: Mention GNU m4 1.4 bugs and Akim's patched version.
9790 * README-alpha: Don't tell people not to package this.
9791
9792 * bootstrap: Don't assume $(...) works; use `...` instead.
9793 Problem reported by Paul Hilfinger. Also, diagnose non-GNU
9794 gettext better.
9795
9796 * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
9797 put into the -d output file, and mention what to do if YYSTYPE is
9798 defined as a macro.
9799
9800 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
9801
9802 Undo change made earlier today: it caused autopoint to not bring
9803 in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
9804 autopoint's.
9805
9806 * bootstrap: Check that gettext version matches what's in
9807 configure.ac. Warn users to ignore robots.txt ERROR 404.
9808 * bootstrap: Undo today's earlier change (logged below).
9809 * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
9810
9811 The gettext version checking is causing more trouble than it's
9812 curing; remove it. Problem reported by Paul Hilfinger.
9813
9814 * bootstrap: Issue a warning that one can expect a message
9815 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
9816 * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
9817
9818 2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
9819
9820 Ensure that the C++ compiler used for testing actually works on a
9821 simple test program; if not, skip the C++-related tests. Problem
9822 reported by Vin Shelton in:
9823 http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
9824
9825 * m4/cxx.m4: New file.

9828 * tests/local.at (AT_COMPILE_CXX): Use it.
9829
9830 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9831
9832 * data/glr.c (yylloc): Output this macro even if locations are not
9833 being generated, as the GLR parser needs it even in that case.
9834 Problem reported by Troy A. Johnson
9835 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
9836
9837 * configure.ac (AC_INIT): Update to 1.875e.
9838
9839 2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
9840
9841 * NEWS: Version 1.875d.
9842 * configure.ac (AC_INIT): Likewise.
9843 * src/parse-gram.c, src/parse-gram.h: Regenerate with 1.875d.
9844
9845 * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
9846 -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
9847 lalr1.cc runs afoul of the first, and the last two are no longer
9848 supported by GCC 3.4.0.
9849 * README: Mention GNU m4 1.4 or later; mention m4 patches.
9850 * HACKING: Use ./bootstrap, not "make update" to import foreign files.
9851
9852 2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
9853
9854 * src/muscle_tab.c (hash_muscle): Accept and return size_t, not
9855 unsigned int, for compatibility with latest gnulib hash module.

9857 * src/symtab.c (hash_symbol, hash_symbol_hasher): Likewise.
9858 * src/uniqstr.c (hash_uniqstr): Likewise.
9859
9860 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
9861
9862 * NEWS: Unescaped newlines are no longer allowed in char & strings.
9863
9864 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER,
9865 SC_CHARACTER,SC_STRING>): Reject unescaped newlines in
9866 character and string literals.
9867 (unexpected_end): New function.
9868 (unexpected_eof): Use it.
9869 (unexpected_newline): New function.
9870 (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>): Coalesce duplicate
9871 actions.
9872
9873 * NEWS: Document %expect-rr.
9874
9875 * bootstrap (--gnulib-srcdir=*, --cvs-user=*):
9876 Fix typo by replacing $1 with $option.
9877 Remove more 'intl'-related files.
9878 Don't DEFUN AM_INTL_SUBDIR twice.
9879
9880 * lib/.cvsignore: Add strndup.h. Remove memchr.c, memcmp.c,
9881 memrchr.c, strcasecmp.c, strchr.c, strrchr.c, strspn.c, strtol.c,
9882 strtoul.c.
9883 * m4/.cvsignore: Add exitfail.m4, extensions.m4, gnulib.m4,
9884 hard-locale.m4, mbstate_t.m4, strerror_r.m4, strndup.m4,
9885 xstrndup.m4. Remove glibc21.m4, intdiv0.m4, inttypes-pri.m4,
9886 inttypes.m4, inttypes_h.m4, isc-posix.m4, lcmessage.m4,
9887 stdint_h.m4, uintmax_t.m4, ulonglong.m4.
9888 * src/.cvsignore: Add *.output.
9889
9890 * src/parse-gram.y: Put copyright notice inside %{ %} so it
9891 gets copied to the output file.
9892
9893 2004-04-28 Paul Eggert <eggert@twinsun.com>
9894
9895 Get files from the gnulib and po repositories, instead of relying
9896 on them being in our CVS. Upgrade to latest versions of gnulib
9897 and Automake.
9898
9899 * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
9900 * bootstrap: Bootstrap from gnulib and po repositories.
9901 Much of this code was stolen from GNU diff and GNU tar's bootstrap.
9902 * README-cvs: Document these changes. Remove version numbers from
9903 mentions of build tools, since they change so often. Mention Flex.
9904
9905 * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
9906 (gl_USE_SYSTEM_EXTENSIONS): Add.
9907 (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
9908 Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
9909 does this for us.
9910 (AC_ISC_POSIX): Remove; we no longer support this
9911 ancient OS, as it gets in the way of latest Autoconf & gnulib.
9912 (AC_HEADER_STDC): Remove: we now assume C89 or better.
9913 (AC_CHECK_HEADERS_ONCE): Use instead of AC_CHECK_HEADERS.
9914 Do not check for C89 headers, except for locale.h which is used
9915 by the Yacc library and must port to K&R hosts.
9916 (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.
9917 Do not check for C89 functions, except for setlocale which is
9918 used by the Yacc library.
9919 (AC_CHECK_DECLS, AC_REPLACE_FUNCS): Remove; no longer needed.
9920 (gl_DIRNAME, gl_ERROR, gl_FUNC_ALLOCA, gl_FUNC_MEMCHR,
9921 gl_FUNC_MEMRCHR, gl_FUNC_STPCPY, gl_FUNC_STRNLEN, gl_FUNC_STRTOL,

9923 gl_QUOTEARG, gl_XALLOC, jm_FUNC_GLIBC_UNLOCKED_IO, jm_FUNC_MALLOC,
9924 AM_GNU_GETTEXT): Remove; now done by:
9925 (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
9926 (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
9927 for us.
9928
9929 * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
9930 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
9931 Define to empty, as gnulib.mk will do the rest for us.
9932 ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
9933 for us.
9934 (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
9935 (lib_SOURCES): New symbol, containing only the non-gnulib libs.
9936
9937 * src/files.c: Include gnulib's xstrndup.h.
9938
9939 * src/system.h (MALLOC): Use xnmalloc, for better overflow checking.
9940 (REALLOC): Use xnrealloc, for likewise.
9941 (xstrndup, stpcpy): Remove decls, as gnulib does this for us now.
9942 (strnlen, memrchr): Remove decls; functions no longer used.
9943 Include <stpcpy.h>.
9944
9945 * config/depcomp, config/install-sh, lib/alloca.c, lib/argmatch.c,

9966 Remove, as these files are now generated automatically
9967 by bootstrap or automake.
9968
9969 * po/ChangeLog: Remove: all but one entry was a duplicate
9970 of this file, and I moved that 2000-11-02 entry here.
9971
9972 * config/.cvsignore: Add Makefile, depcomp, install-sh.
9973 * lib/.cvsignore: Add alloca.c, alloca.h, alloca_.h, argmatch.c,

9990
9991
9992 * Makefile.maint (GZIP_ENV): Don't use --rsyncable if gzip doesn't
9993 support it. (The latest stable gzip doesn't.)
9994
9995 2004-04-27 Paul Eggert <eggert@twinsun.com>
9996
9997 * data/lalr1.cc (Parser::stos_) [! YYDEBUG]: Define even in this
9998 case, as stos_ is now used by destructors due to the 2004-02-09
9999 change.
10000
10001 Remove more K&R C support.
10002 * lib/libiberty.y (PARAMS): Remove. All uses removed.
10003 * lib/subpipe.c (errno): Remove decl.
10004 Include <stdlib.h> unconditionally.
10005 (EXIT_FAILURE): Remove macro.
10006 * src/complain.c (vfprintf, strerror): Remove.
10007 * src/system.h: Include limits.h, stdlib.h, string.h, locale.h
10008 unconditionally.
10009 (EXIT_FAILURE, EXIT_SUCCESS, setlocale): Remove defns.
10010 Use latest Autoconf recommendations for including inttypes.h, stdint.h.
10011 (strchr, strspn, memchr): Remove decls.
10012 * tests/calc.at (_AT_DATA_CALC_Y): Include stdlib.h, string.h
10013 unconditionally. Do not declare perror.
10014 * tests/conflicts.at (%nonassoc and eof): Include stdlib.h
10015 unconditionally.
10016
10017 * src/complain.c (_): Remove useless defn, as system.h defines this.
10018
10019 * lib/bitset.h (__INT_TO_PTR): Remove; workaround no longer needed
10020 with latest obstack.h.
10021 * lib/ebitset.c (ebitset_elt_alloc): Don't bother to cast args
10022 to procedure types, as obstack.h now does that for us.
10023 * lib/lbitset.c (lbitset_elt_alloc): Likewise.
10024
10025 * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
10026 so that this include file can stand alone.
10027 * lib/subpipe.c: Do not include <sys/types.h>, as subpipe.h
10028 does this now. Include subpipe.h first after config.h, to
10029 test whether it can stand alone.
10030
10031 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
10032 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
10033 unused declaration.
10034
10035 * tests/synclines.at (%union synch line): Put a dummy member in
10036 the union, because empty unions aren't allowed in C. Caught
10037 by GCC 3.4.0.
10038
10039 2004-04-13 Jim Meyering <jim@meyering.net>
10040
10041 * src/conflicts.c (conflicts_print): Correct format string typo:
10042 use `%%' to produce literal `%'. (trivial change)
10043
10044 2004-03-30 Paul Eggert <eggert@twinsun.com>
10045
10046 * src/getargs.c (version): Update copyright year to 2004.
10047
10048 * data/c.m4 (b4_int_type): Use 'short int' rather than
10049 'short', and similarly for 'long', 'unsigned', etc.

10053 * data/lalr1.cc (user_token_number_max_, user_token_number_max_,
10054 translate_, seq_, [], pop, Slice, range_, operator+, operator+=):
10055 Likewise.
10056 * data/yacc.c (b4_int_type, yyss, YYSTACK_BYTES, yysigned_char,
10057 yy_stack_print, yyparse): Likewise.
10058 * doc/bison.texinfo (Prologue, Multiple Types): Likewise.

10084
10085 2004-03-25 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
10086
10087 * src/parse-gram.y: Define PERCENT_EXPECT_RR.
10088 (declaration): Replace expected_conflicts with expected_sr_conflicts.
10089 Add %expect-rr rule.
10090
10091 * src/scan-gram.l: Recognize %expect-rr.
10092
10093 * src/conflicts.h (expected_sr_conflicts): Rename from
10094 expected_conflicts.
10095 (expected_rr_conflicts): Declare.
10096
10097 * src/conflicts.c (expected_sr_conflicts): Rename from

10099 (expected_rr_conflicts): Define.
10100 (conflicts_print): Check r/r conflicts against expected_rr_conflicts
10101 for GLR parsers.
10102 Use expected_sr_conflicts in place of expected_conflicts.
10103 Warn if expected_rr_conflicts used in non-GLR parser.
10104
10105 * doc/bison.texinfo: Add documentation for %expect-rr.
10106
10107 2004-03-08 Paul Eggert <eggert@gnu.org>
10108
10109 Add support for hex token numbers. Suggested by Odd Arild Olsen in
10110 <http://lists.gnu.org/archive/html/bison-patches/2004-03/msg00000.html>.
10111
10112 * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
10113 in lalr1.cc.
10114 * doc/bison.texinfo (Token Decl): Add hexadecimal token numbers.
10115 * src/scan-gram.l (scan_integer): New function.
10116 ({int}): Use it.
10117 (0[xX][0-9abcdefABCDEF]+): New pattern, to support hex numbers.
10118 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>, \\x[0-9abcdefABCDEF]+,
10119 handle_action_dollar, handle_action_at, convert_ucn_to_byte):
10120 Say "long int", not "long", for uniformity with GNU style.
10121
10122 2004-02-25 Paul Eggert <eggert@twinsun.com>
10123
10124 * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
10125 compilers. This fixes a problem with Intel's C++ compiler being
10126 chatty, reported by Guido Trentalancia in
10127 <http://lists.gnu.org/archive/html/bug-bison/2004-02/msg00030.html>.
10128
10129 2004-02-09 Alexandre Duret-Lutz <adl@gnu.org>
10130
10131 Support %destructor and merge error locations in lalr1.cc.
10132
10133 * data/lalr1.cc (b4_cxx_destruct_def): New macro.
10134 (Parser::stos_): Define unconditionally.
10135 (Parser::destruct_): New method. Generate its body with
10136 b4_yydestruct_generate.
10137 (Parser::error_start_): New attribute.
10138 (Parser::parse) <yyerrlab, yyerrlab1>: Call destruct_ on erroneous
10139 token which are discarded.
10140 (Parser::parse) <yyerrlab, yyerrorlab, yyerrlab1>: Update
10141 error_start_ when erroneous token are discarded.
10142 (Parser::parse) <yyerrlab1>: Compute the location of the error
10143 token so that it covers all the discarded tokens.
10144 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust so
10145 it can be called with `%skeleton "lalr1.cc"', and do that.
10146
10147 2004-02-02 Paul Eggert <eggert@twinsun.com>
10148
10149 * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions
10150 $(top_srcdir)/lib and ../lib. This fixes a bug reported
10151 by Paul Hilfinger; the old INCLUDES value didn't mention ../lib.
10152 There's no need to mention top_builddir since Automake does that
10153 for us.
10154 (INCLUDES): Remove, as Automake says it's obsolescent.
10155 Contents migrated into AM_CPPFLAGS as described above.
10156 * lib/Makefile.am (INCLUDES): Remove; obsolescent.
10157
10158 2004-01-14 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
10159
10160 * data/glr.c (yytokenName): Bullet-proof against YYEMPTY token.
10161 (yyreportSyntaxError): Handle case where lookahead token is
10162 YYEMPTY.
10163
10164 2004-01-13 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10165
10166 * data/glr.c: Put casts on uses of YYREALLOC and YYMALLOC so that
10167 resulting parsers are compilable with C++.
10168
10169 2003-12-23 Paul Eggert <eggert@twinsun.com>
10170
10171 * config/depcomp, config/install-sh: Sync with Automake 1.8.
10172 * src/output.c (output_skeleton): Rename local var.
10173 * tests/input.at (Torturing the Scanner): Don't use \x0 or \0 in
10174 Bison tokens, as this runs afoul of the 2003-10-07 change that
10175 disallowed NUL bytes in character constants or string literals.
10176
10177 * tests/local.at: Require Autoconf 2.59's Autotest.
10178 * tests/testsuite.at: Don't include local.at, since we now assume
10179 Autoconf 2.59 or later. Autoconf 2.59 had some problems with
10180 including it.
10181 * tests/Makefile.am ($(TESTSUITE)): Remove warning about ignoring
10182 multiple inclusion warnings.
10183
10184 2003-12-02 Akim Demaille <akim@epita.fr>
10185
10186 * doc/bison.texinfo (How Can I Reset the Parser): More about start
10187 conditions.
10188 From Bruno Haible.
10189
10190 2003-11-18 Alexandre Duret-Lutz <adl@gnu.org>
10191
10192 * doc/bison.texinfo (Bison Options): Escape `@' in `$@'.
10193
10194 2003-10-07 Paul Eggert <eggert@twinsun.com>
10195
10196 * tests/Makefile.am (clean-local): Don't run 'testsuite --clean'
10197 if testsuite doesn't exist.
10198
10199 * doc/bison.texinfo (Symbols): NUL bytes are not allowed in string
10200 literals, unfortunately.
10201 * src/scan-gram.l (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>):
10202 Complain about NUL bytes in character constants or string literals.
10203
10204 2003-10-05 Paul Eggert <eggert@twinsun.com>
10205
10206 * NEWS: Don't document %no-default-prec, as it's still
10207 too experimental.
10208 * doc/bison.texinfo: Document %no-default-prec only if
10209 the defaultprec flag is set. Normally it's not.
10210
10211 2003-10-04 Paul Eggert <eggert@twinsun.com>
10212
10213 * data/glr.c (b4_rhs_value, b4_rhs_location): Yield a
10214 non-modifiable lvalue, instead of a modifiable one.
10215 * doc/bison.texinfo (Actions): Document that $$ can
10216 be assigned to. Do not claim that $$ and $N are
10217 array element references: user code should not rely on this.
10218
10219 2003-10-01 Paul Eggert <eggert@twinsun.com>
10220
10221 * src/parse-gram.h (PERCENT_NO_DEFAULT_PREC): New token.
10222 (grammar_declaration): Use it.
10223 * src/scan-gram.l: New token %no-default-prec.
10224 * tests/conflicts.at: Revamp tests to use %no-default-prec.
10225 * NEWS, doc/bison.texinfo: Document the above.
10226
10227 2003-10-01 Akim Demaille <akim@epita.fr>
10228
10229 VCG no longer supports long_straight_phase.
10230
10231 * src/vcg.c, src/vcg.h: Remove the handling of long_straight_phase.
10232 * src/print_graph.c (print_graph): Adjust.
10233
10234 2003-09-30 Frank Heckenbach <frank@g-n-u.de>
10235 and Paul Eggert <eggert@twinsun.com>
10236
10237 * doc/bison.texinfo (Decl Summary, Contextual Precedence,
10238 Table of Symbols): Document %default-prec.
10239 * src/parse-gram.y (PERCENT_DEFAULT_PREC): New token.
10240 (grammar_declaration): Set default_prec on %default-prec.
10241 * src/scan-gram.l (%default-prec): New token.
10242 * src/reader.h (default_prec): New flag.
10243 * src/reader.c: Likewise.
10244 (packgram): Handle it.
10245 * tests/conflicts.at (%default-prec without %prec,
10246 %default-prec with %prec, %default-prec 1): New tests.
10247
10248 2003-09-30 Paul Eggert <eggert@twinsun.com>
10249
10250 * tests/testsuite.at: Include local.at, not input.at, fixing
10251 a typo in the 2003-08-25 patch.
10252
10253 2003-08-27 Akim Demaille <akim@epita.fr>
10254
10255 * data/lalr1.cc (yyparse) [__GNUC__]: "Use" yyerrorlab to pacify
10256 GCC warnings.
10257
10258 2003-08-26 Akim Demaille <akim@epita.fr>
10259
10260 * config/announce-gen (print_changelog_deltas): Neutralize "<#" as
10261 "<\#" to avoid magic from Gnus when posting parts of this script.
10262
10263 2003-08-26 Akim Demaille <akim@epita.fr>
10264
10265 * data/lalr1.cc (Parser::report_syntax_error_): New, extracted from
10266 (Parser::parse): here.
10267 Adjust: nerrs and errstatus is now replaced by...
10268 (Parser::nerrs_, Parser::errstatus_): New.
10269
10270 2003-08-25 Akim Demaille <akim@epita.fr>
10271
10272 * config/announce-gen, Makefile.cfg: New.
10273 * Makefile.am: Adjust.
10274 * GNUmakefile, Makefile.maint: Update from CVS Autoconf, but
10275 keeping local WGET and WGETFLAGS modifications from Paul Eggert.
10276
10277 2003-08-25 Akim Demaille <akim@epita.fr>
10278
10279 When reducing initial empty rules, Bison parser read an initial
10280 location that is not defined. This results in garbage, and that
10281 affects Bison's own parser. Therefore we need (i) to extend Bison
10282 to support a means to initialize this location, and (ii) to use
10283 this CVS Bison to fix CVS Bison's parser.
10284
10285 * src/reader.h, reader.c (epilogue_augment): Remove, replace
10286 with...
10287 * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.
10288 * src/parse-gram.y: Adjust.
10289 (%initial-action): New.
10290 (%error-verbose): Since we require CVS Bison, there is no reason
10291 not to use it.
10292 * src/scan-gram.l: Adjust.
10293 * src/Makefile.am (YACC): New, to make sure we use our own parser.
10294 * data/yacc.c (yyparse): Use b4_initial_action.
10295
10296 2003-08-25 Akim Demaille <akim@epita.fr>
10297
10298 * doc/bison.texinfo: Don't promote stdout for error messages.
10299
10300 2003-08-25 Akim Demaille <akim@epita.fr>
10301
10302 * data/lalr1.cc (Parser::reduce_print_): Remove unused yyi.
10303 From Alexandre Duret-Lutz.
10304
10305 2003-08-25 Akim Demaille <akim@epita.fr>
10306
10307 Version 1.875c.
10308
10309 2003-08-25 Akim Demaille <akim@epita.fr>
10310
10311 * data/lalr1.cc (Parser::stack_print_, YY_STACK_PRINT): New.
10312 Use them.
10313
10314 2003-08-25 Akim Demaille <akim@epita.fr>
10315
10316 * data/lalr1.cc (Parser::reduce_print_): New.
10317 Use it.
10318
10319 2003-08-25 Akim Demaille <akim@epita.fr>
10320
10321 Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
10322 error recovery loops. This patch is based on
10323 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
10324 Also, augment the similarity between lalr1.cc and yacc.c.
10325 Note: the locations of error recovery rules are not correct yet.
10326
10327 * data/lalr1.cc: Comment changes to augment the similarity between
10328 lalr1.cc and yacc.c.
10329 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
10330 (yyerrlab1): Remove, but where it used to be (now the bottom part of
10331 yyerrlab), when hitting EOF, pop the whole stack here instead of
10332 merely falling thru the default error handling mechanism.
10333 (yyerrorlab): New label, with the old contents of YYERROR,
10334 plus the following change: pop the stack of rhs corresponding
10335 to the production that invoked YYERROR. That is how Yacc
10336 behaves (required by POSIX).
10337 * tests/calc.at (AT_CHECK_CALC_LALR1_CC): No longer expected to
10338 fail.
10339
10340 2003-08-25 Akim Demaille <akim@epita.fr>
10341
10342 Tune local.at so that people can "autom4te -l autotest calc.at -o
10343 calc" for instance, to extract a sub test suite.
10344
10345 * tests/testsuite.at: Move the initialization, Autotest version
10346 requirement, and AT_TESTED invocation into...
10347 * tests/local.at: here.
10348 * tests/testsuite.at: Include it for compatibility with Autoconf
10349 2.57.
10350 * tests/Makefile.am ($(TESTSUITE)): Report that the warning should
10351 be ignore.
10352
10353 2003-08-04 Paul Eggert <eggert@twinsun.com>
10354
10355 Rework code slightly to avoid gcc -Wtraditional warnings.
10356 * data/glr.c (yyuserMerge): Return void, not YYSTYPE.
10357 The returned value is now stored in *YY0. All callers changed.
10358 * src/output.c (merge_output): Adjust to the above change.
10359
10360 2003-07-26 Paul Eggert <eggert@twinsun.com>
10361
10362 * data/glr.c (YYASSERT): New macro.
10363 (yyfillin, yydoAction, yyglrReduce, yysplitStack,
10364 yyresolveStates, yyprocessOneStack):
10365 Use `YYASSERT (FOO);' rather than `if (! (FOO)) abort ();'.
10366 Derived from a suggestion by Frank Heckenbach.
10367
10368 2003-07-25 Paul Eggert <eggert@twinsun.com>
10369
10370 * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
10371 for portability to K&R C (after ansi2knr, presumably). See
10372 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
10373 by Frank Heckenbach, though I have omitted the structure-initialization
10374 part of his glr-knr.diff patch since I recall that the Portable
10375 C Compiler didn't require that change.
10376
10377 Let the user specify how to allocate and free memory.
10378 Derived from a suggestion by Frank Heckenbach in
10379 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.
10380 * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
10381 All uses of free, malloc, realloc changed to use these macros,
10382 and unnecessary casts removed.
10383 * data/yacc.c (YYFREE, YYMALLOC): Likewise.
10384
10385 2003-07-06 Matthias Mann <MatthiasMann@gmx.de>
10386
10387 * data/lalr1.cc (operator<<(std::ostream&, const Position&)):
10388 use s.empty() rather than s == "" to test for empty string; see
10389 <http://lists.gnu.org/archive/html/bison-patches/2003-07/msg00003.html>
10390 (trivial change)
10391
10392 2003-06-25 Akim Demaille <akim@epita.fr>
10393
10394 * config/depcomp, config/install-sh: Update from masters.
10395
10396 2003-06-20 Paul Eggert <eggert@twinsun.com>
10397
10398 * data/glr.c (YYLLOC_DEFAULT): Parenthesize arguments as needed,
10399 and return properly parenthesized result.
10400 * data/lalar1.cc (YYLLOC_DEFAULT): Likewise.
10401 * data/yacc.c (YYLLOC_DEFAULT): Likewise.
10402 Remove unnecessary parentheses from uses.
10403 * doc/bison.texinfo (Location Default Action): Describe the
10404 conventions for parentheses.
10405
10406 2003-06-19 Paul Eggert <eggert@twinsun.com>
10407
10408 * data/glr.c (yyremoveDeletes, yy_reduce_print, yyglrReduce,
10409 yyreportTree): Do not assume that size_t is the same width as int,
10410 when printing sizes. Print sizes using an unsigned format.
10411 Problem reported by Frank Heckenbach in
10412 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00035.html>.
10413
10414 Port to Forte Developer 7 C compiler.
10415 * data/glr.c (struct YYLTYPE): If locations are not being used,
10416 declare a single dummy member, as empty structs do not conform
10417 to the C standard.
10418 (YYERROR, YYBACKUP): Do not use "do { ...; return foo; } while (0)";
10419 the Forte Developer 7 C compiler complains that end-of-loop
10420 code is not reached.
10421
10422 2003-06-17 Paul Eggert <eggert@twinsun.com>
10423
10424 * lib/libiberty.h (PARAMS): Spell argument as Args, not as X, to
10425 avoid warnings from picky compilers about redefinition of PARAMS.
10426
10427 2003-06-17 Paul Eggert <eggert@twinsun.com>
10428
10429 Version 1.875b.
10430
10431 * NEWS: Document 1.875b.
10432
10433 * lib/bbitset.h: Do not include config.h; that's the includer's job.
10434 Do not include <sys/types.h>; shouldn't be needed on a C89 host.
10435 * lib/bitset.h (bitset_compatible_p): Indent as per GNU standard.
10436 Don't use 'index' in comments, as it's a builtin fn on some hosts.
10437 * lib/bitset_stats.c: Include gettext.h unconditionally, as
10438 per recent gettext manual's suggestion.
10439 * lib/ebitset.c (ebitset_resize, ebitset_unused_clear):
10440 Use prototypes, not old-style definitions.
10441 * lib/lbitset.c (lbitset_unused_clear): Likewise.
10442 * lib/vbitset.c (vbitset_resize, vbitset_ones, vbitset_zero,
10443 vbitset_empty_p, vbitset_copy1, vbitset_not, vbitset_equal_p,
10444 vbitset_subset_p, vbitset_disjoint_p, vbitset_and, vbitset_and_cmp,
10445 vbitset_andn, vbitset_andn_cmp, vbitset_or, vbitset_or_cmp,
10446 vbitset_xor, vbitset_xor_cmp, vbitset_and_or, vbitset_and_or_cmp,
10447 vbitset_andn_or, vbitset_andn_or_cmp, vbitset_or_and,
10448 vbitset_or_and_cmp, vbitset_copy): Likewise.
10449
10450 * lib/libiberty.h: Do not include config.h; that's the includer's job.
10451 Do not include <stdlib.h>.

10453 (ATTRIBUTE_NORETURN): Remove.
10454 (ATTRIBUTE_UNUSED): Define unconditionally.
10455
10456 Upgrade to 2003-06-08 libbitset, submitted by Michael Hayes in:
10457 <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00005.html>
10458 * lib/Makefile.am (bitsets_sources): Add vbitset.c, vbitset.h.
10459 * lib/vbitset.c, lib/vbitset.h: New files.
10460 * lib/abitset.c, lib/bbitset.h, lib/bitset.c, lib/bitset.h,
10461 lib/bitset_stats.c, lib/ebitset.c, lib/lbitset.c: Import
10462 from libbitset.
10463
10464 * doc/bison.texinfo (How Can I Reset the Parser): Renamed from
10465 `How Can I Reset @code{yyparse}', since texinfo does not allow
10466 arbitrary @ in node names.
10467
10468 * m4/Makefile.am (EXTRA_DIST): Add the following files, which
10469 shouldn't be needed according to the gettext 0.12.1 documentation
10470 but which seem to be needed anyway: codeset.m4 glibc21.m4
10471 intdiv0.m4 inttypes-pri.m4 inttypes.m4 inttypes_h.m4 isc-posix.m4
10472 lcmessage.m4 nls.m4 po.m4 stdint_h.m4 uintmax_t.m4 ulonglong.m4.
10473 * po/Makefile.in.in: Upgrade to gettext 0.12.1 version.
10474
10475 * lib/.cvsignore: Add stdbool.h.
10476 * m4/.cvsignore: Add nls.m4, po.m4.
10477
10478 Upgrade to CVS gnulib.
10479 * stdbool_.h: File renamed from stdbool.h.in.
10480 * configure.ac (AM_STDBOOL_H): Invoke this instead of
10481 AC_HEADER_STDBOOL.
10482 (AM_GNU_GETTEXT): Put brackets around args, as latest manual suggests.
10483 (AM_GNU_GETTEXT_VERSION): Update to 0.12.1.
10484 * lib/Makefile.am (EXTRA_DIST): Add stdbool_.h.
10485 (MOSTLYCLEANFILES): New var.
10486 ($(libbison_a_OBJECTS)): Depend on $(STDBOOL_H).
10487 (stdbool.h): New rule.
10488 * lib/dirname.c, lib/dirname.h, lib/hash.c, lib/hash.h,
10489 lib/malloc.c, lib/obstack.h, lib/quote.c, lib/realloc.c,
10490 lib/strcasecmp.c, lib/xalloc.h, m4/alloca.m4, m4/onceonly.m4,
10491 m4/quote.m4: Upgrade to today's gnulib.
10492
10493 * tests/calc.at (AT_CHECK_CALC): New option EXPECTED-TO-FAIL.
10494 (AT_CHECK_CALC_LALR1_CC): Use it, since the C++ LALR parser fails
10495 the tests right now.
10496 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Ensure yylex and
10497 yyerror are declared before use; C99 requires this.
10498
10499 2003-06-09 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
10500
10501 * data/glr.c (YYERROR): Update definition to reset yyerrState to 0
10502 first.
10503 (yyrecoverSyntaxError): Correct the logic for setting and testing
10504 yyerrState.
10505 Correct comment on handling EOF.
10506 Allow states with only a default reduction, rather than failing
10507 (I can't quite reconstruct why these were not allowed before).
10508
10509 Fixes to avoid problem that $-N rules in GLR parsers can cause
10510 buffer overruns, corrupting state.
10511
10512 * src/output.c (prepare_rules): Output max_left_semantic_context
10513 definition.
10514 * src/reader.h (max_left_semantic_context): New variable declaration.
10515 * src/scan-gram.l (max_left_semantic_context): Define.
10516 (handle_action_dollar): Update max_left_semantic_context.
10517 * data/glr.c (YYMAXLEFT): New definition.
10518 (yydoAction): Increase size of yyrhsVals by YYMAXLEFT.
10519 (yyresolveAction): Ditto.
10520
10521 Fixes to problems with location handling in GLR parsers reported by
10522 Frank Heckenbach (2003/06/05).
10523
10524 * data/glr.c (YYLTYPE): Make trivial if locations not used.
10525 (YYRHSLOC): Add parentheses, and define only if locations used.
10526 (YYLLOC_DEFAULT): Add parentheses, and give trivial definition if
10527 locations not used.
10528 (yyuserAction): Use YYLLOC_DEFAULT to set *yylocp.
10529 (yydoAction): Remove redundant initialization of *yyvalp and *yylocp.
10530
10531 * tests/cxx-type.at: Exercise location information; update tests
10532 to differentiate output with and without locations.
10533 Remove forward declarations of yylex and yyerror---caused errors
10534 because default YYLTYPE not yet defined.
10535 Change semantic actions to compute strings, rather than printing
10536 them directly (to test proper passing of semantics values). Change
10537 output to prefix notation and update test data and expected results.
10538 (yylex): Track locations.
10539 (stmtMerge): Return value rather than printing, and include arguments
10540 in value.
10541
10542 2003-06-03 Paul Eggert <eggert@twinsun.com>
10543
10544 Avoid warnings generated by GCC 2.95.4 when Bison is
10545 configured with --enable-gcc-warnings.
10546 * data/lalr1.cc (yy::]b4_parser_class_name[::parse,
10547 yy::]b4_parser_class_name[::translate_,
10548 yy::Stack::operator[] (unsigned),
10549 yy::Stack::operator[] (unsigned) const,
10550 yy::Slice::operator[] (unsigned),
10551 yy::Slice::operator[] (unsigned) const):
10552 Rename local vars to avoid warnings.
10553 * tests/glr-regression.at (Improper handling of embedded actions
10554 and $-N in GLR parsers): Remove unused local variable from yylex.
10555 * tests/regression.at (_AT_DATA_DANCER_Y): Declare yylex to take
10556 (void) as arg when not pure, since we now assume C89 when building
10557 Bison. Pacify GCC by using parameter.
10558
10559 2003-06-02 Paul Eggert <eggert@twinsun.com>
10560
10561 * data/lalr1.cc (yy::Position::lines, yy::Position::columns,
10562 yy::Location::lines, yy::Location::columns): Rename arguments
10563 to avoid shadowing; this removes a warning generated by GCC 3.3.
10564
10565 2003-06-01 Paul Eggert <eggert@twinsun.com>
10566
10567 Don't pass C-only warning optins (e.g., -Wmissing-declarations)
10568 to g++, as GCC 3.3 complains if you do it.
10569 * configure.ac (WARNING_CXXFLAGS): New subst. Set it to
10570 everything that WARNING_CFLAGS has, except omit warnings
10571 not suitable for C++.
10572 (AC_PROG_CXX): Use this instead of AC_CHECK_PROGS([CXX], [g++]).
10573 * tests/atlocal.in (CXXFLAGS): New var.
10574 * tests/local.at (AT_COMPILE_CXX): Use it instead of CFLAGS.
10575
10576 Fix a GLR parser bug I reported in February; see
10577 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
10578 The problem was that GLR parsers did not conform to the C standard,
10579 because actions like { $1 = $2 + $3; } expanded to expressions
10580 that invoked YYFILL in separate subexpressions, and YYFILL assigned
10581 to a local variable. The C standard says that expressions
10582 like (var = f ()) + (var = f ()) have undefined behavior.
10583 Another problem was that GCC sometimes issues warnings that
10584 yyfill and its parameters are unused.
10585
10586 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
10587 as possibly unused.
10588 (yyfill): New function.
10589 (YYFILL): Use it.
10590 (yyuserAction): Change type of yynormal to bool, so that it matches
10591 the new yyfill signature. Mark it as possibly unused.
10592
10593
10594 Follow up on a bug I reported in February, where a Bison-generated
10595 parser can loop. Provide a test case and a fix for yacc.c. I
10596 don't have a fix for lalr1.cc or for glr.c, unfortunately.
10597 The original bug report is in:
10598 <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
10599
10600 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
10601 macro's size was becoming unwieldy.
10602 (yyerrlab): Do not discard an empty lookahead symbol, as this
10603 might destroy garbage.
10604 (yyerrorlab): New label, with the old contents of YYERROR,
10605 plus the following change: pop the stack of rhs corresponding
10606 to the production that invoked YYERROR. That is how Yacc
10607 behaves, and POSIX requires this behavior.
10608 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
10609 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
10610 Define 'alarm' to do nothing if unistd.h is not available.
10611 Add a new rule "exp: '-' error;" to test the above change to
10612 data/yacc.c. Use 'alarm' to abort any test taking longer than
10613 10 seconds, as it's probably looping.
10614 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
10615 Also, the new yacc.c generates two fewer diagnostics for an
10616 existing test.
10617
10618 2003-05-24 Paul Eggert <eggert@twinsun.com>
10619
10620 * data/glr.c (YYSTACKEXPANDABLE): Do not evaluate
10621 YYSTYPE_IS_TRIVIAL or YYSTYPE_IS_TRIVIAL unless they are defined.
10622 This fixes a problem reported by John Bowman when the Compaq/HP
10623 Alpha cxx compiler happy (e.g. using cxx -D__USE_STD_IOSTREAM
10624 -ansi -Wall -gall).
10625 * data/yacc.c (union yyalloc): Likewise.
10626 (YYCOPY): Do not evaluate __GNUC__ unless it is defined.
10627
10628 Switch from 'int' to 'bool' where that makes sense.

10633 abitset_and_or_cmp, abitset_andn_or_cmp, abitset_or_and_cmp):
10634 Return or accept bool, not int. All callers changed.

10649 ebitset_op3_cmp, ebitset_and_cmp, ebitset_andn_cmp, ebitset_or_cmp,
10650 ebitset_xor_cmp): Likewise.
10651 * lib/lbitset.c (lbitset_elt_zero_p, lbitset_equal_p, lbitset_copy_cmp,
10652 lbitset_test, lbitset_empty_p, lbitset_subset_p, lbitset_disjoint_p,
10653 lbitset_op3_cmp, lbitset_and_cmp, lbitset_andn_cmp, lbitset_or_cmp,
10654 lbitset_xor_cmp): Likewise.
10655 * lib/bbitset.h: Include <stdbool.h>.
10656 (struct bitset_vtable): The following members now return bool, not
10657 int: toggle, test, empty_p, disjoint_p, equal_p, subset_p,
10658 and_cmp, andn_cmp, or_cmp, xor_cmp, and_or_cmp, andn_or_cmp,
10659 or_and_cmp).
10660 * src/conflicts.c (count_rr_conflicts): Likewise.
10661 * lib/bitset_stats.h (bitset_stats_enabled): Now bool, not int.
10662 All uses changed.
10663 * lib/ebitset.c (ebitset_obstack_init): Likewise.
10664 * lib/lbitset.c (lbitset_obstack_init): Likewise.
10665 * src/getargs.c (debug_flag, defines_flag, locations_flag,

10667 graph_flag): Likewise.
10668 * src/getargs.h (debug_flag, defines_flag, locations_flag,

10687 * src/state.c (state_rule_lookaheads_print): Likewise.
10688

10690
10691 2003-05-14 Paul Eggert <eggert@twinsun.com>
10692
10693 * src/parse-gram.y (rules_or_grammar_declaration): Require a
10694 semicolon after a grammar declaration, in the interest of possible
10695 future changes to the Bison input language.
10696 Do not allow a stray semicolon at the start of the grammar.
10697 (rhses.1): Allow one or more semicolons after any rule, including
10698 just before "|" as required by POSIX.
10699 * tests/input.at (Torturing the Scanner): Add tests for ";|" in a
10700 grammar.
10701
10702 2003-05-14 Alexandre Duret-Lutz <adl@gnu.org>
10703
10704 %parse-param support for lalr1.cc.
10705
10706 * data/lalr1.cc (b4_parse_param_decl, b4_parse_param_cons,
10707 b4_cc_constructor_calls, b4_cc_constructor_call,
10708 b4_parse_param_vars, b4_cc_var_decls, b4_cc_var_decl): New m4
10709 definitions.
10710 (yy::b4_parser_class_name::b4_parser_class_name): Take extra
10711 parse-param arguments.
10712 (yy::b4_parser_class_name): Declare instance variables to
10713 hold parse-param arguments.
10714 * tests/calc.at: s/value/semantic_value/ because value clashes
10715 with a member of yy::b4_parser_class_name. Adjust C++ code
10716 to handle %parse-param. Enable %parse-param test in C++.
10717
10718 2003-05-12 Paul Eggert <eggert@twinsun.com>
10719
10720 * doc/bison.texinfo (How Can I Reset @code{yyparse}): Reword the
10721 English a bit. Fix fclose typo. Change "const char" to "char
10722 const", and use ANSI C rather than K&R for "main". Suggest
10723 YY_FLUSH_BUFFER over yyrestart (as that is what Flex recommends)
10724 and suggest yy_switch_to_buffer.
10725
10726 2003-05-05 Paul Eggert <eggert@twinsun.com>
10727
10728 * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
10729 C89. This avoids a diagnostic on compilers that define __STDC__
10730 to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
10731 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10732
10733 2003-05-03 Paul Eggert <eggert@twinsun.com>
10734
10735 * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
10736 Do not overrun array bounds.
10737 This should fix a bug reported today by Olatunji Oluwabukunmi in
10738 <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
10739
10740 2003-04-29 Akim Demaille <akim@epita.fr>
10741
10742 * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
10743 * src/getargs.c, src/getargs.h: here, as bool, not int.
10744 (nondeterministic_parser): New.
10745 * src/parse-gram.y, src/scan-gram.l: Support
10746 %nondeterministic-parser.
10747 * src/output.c (prepare): Use nondeterministic_parser instead
10748 of glr_parser where appropriate.
10749 * src/tables.c (conflict_row, action_row, save_row)
10750 (token_actions, token_actions, pack_vector): Ditto.
10751
10752 2003-04-29 Akim Demaille <akim@epita.fr>
10753
10754 * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
10755
10756 2003-04-29 Akim Demaille <akim@epita.fr>
10757
10758 * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
10759 with %pure-parser and %locations to exercise the patch from Yakov
10760 Markovitch below.
10761
10762 2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
10763
10764 * data/yacc.c: (b4_lex_param): Corrected for the case where
10765 %lex-param is provided and %pure-parser isn't.
10766
10767 2003-04-27 Paul Eggert <eggert@twinsun.com>
10768
10769 Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
10770 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
10771 * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
10772 if it is not defined.
10773 (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
10774
10775 2003-04-26 Paul Eggert <eggert@twinsun.com>
10776
10777 * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
10778 Declare to be of type suitable for the ninf value itself, not of
10779 type suitable for the corresponding table, since the latter might
10780 be unsigned but the ninf value might be negative. This fixes a
10781 bug reported by Alexandre Duret-Lutz in
10782 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
10783
10784 * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
10785 invokes it. We shouldn't invoke it twice because it will attempt
10786 to put error.o in the archive twice. This fixes a glitch reported
10787 by Martin Mokrejs in
10788 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
10789
10790 2003-04-21 Paul Eggert <eggert@twinsun.com>
10791
10792 * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
10793 to gnulib.
10794
10795 2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
10796
10797 * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
10798 Fix obvious typo that results in uncompilable GLR parsers
10799 when both %pure-parser and %locations are used. (trivial change)
10800
10801 2003-04-17 Paul Eggert <eggert@twinsun.com>
10802
10803 * src/scan-gram.l: Add %option nounput, since we no longer use unput.
10804 (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
10805 Do not insert the expected token via unput, as this runs afoul
10806 of a POSIX-compatibility bug in flex 2.5.31.
10807 All uses changed to BEGIN the parent state,
10808 since we no longer insert the expected token via unput.
10809 * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
10810 that is no longer emitted after the above change.
10811
10812 * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
10813 the first one. This change is from Paul Hilfinger, and it fixes
10814 regression reported by Werner Lemberg in
10815 <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
10816
10817 (resolve_sr_conflict): Don't invoke state_errs_set
10818 unless one or more tokens have been explicitly made errors.
10819 Otherwise, the above change causes Bison to abort.
10820
10821 * tests/existing.at (GNU pic Grammar): New test case, taken from
10822 Lemberg's email.
10823
10824 2003-03-31 Akim Demaille <akim@epita.fr>
10825
10826 * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
10827
10828 2003-03-31 Akim Demaille <akim@epita.fr>
10829
10830 * src/output.c (prepare_symbols): Avoid trailing spaces in the
10831 output.
10832
10833 2003-03-31 Akim Demaille <akim@epita.fr>
10834
10835 * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
10836 From Paul Hilfinger.
10837
10838 2003-03-29 Akim Demaille <akim@epita.fr>
10839
10840 * m4/error.m4: Do not put under dynamic conditions some code which
10841 expansion is under static control.
10842
10843 2003-03-29 Akim Demaille <akim@epita.fr>
10844
10845 * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
10846
10847 2003-03-29 Akim Demaille <akim@epita.fr>
10848
10849 * doc/bison.texinfo (Strings are Destroyed): New.
10850
10851 2003-03-13 Paul Eggert <eggert@twinsun.com>
10852
10853 * .cvsignore: Add configure.lineno.
10854 * src/.cvsignore: Add yacc.
10855 * tests/.cvsignore: Add testsuite.log.
10856 * doc/fdl.texi: Sync with latest FSF version.
10857
10858 2003-03-12 Paul Eggert <eggert@twinsun.com>
10859
10860 * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
10861 (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
10862 cursor, instead of leaving it undefined. This fixes a bug
10863 reported by Tim Van Holder in
10864 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
10865 * tests/input.at (Torturing the Scanner): Test the scanner on
10866 an empty input file, which was Tim Van Holder's test case.
10867
10868 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
10869 <sys/resource.h> can be included, include sys/time.h and
10870 sys/times.h first, if available. This works around the SunOS
10871 4.1.4 porting bug reported by Bruce Becker in
10872 <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
10873
10874 * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
10875 AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
10876 AC_HEADER_SYS_WAIT.
10877
10878 Merge changes from gnulib. This was prompted because the CVS
10879 snapshot didn't build on Solaris 7 due to strnlen problems.
10880
10881 These changes need to be merged back into gnulib:
10882 * lib/hash.c: Include <stdbool.h> unconditionally.
10883 * m4/onceonly.m4 (m4_quote): New macro.
10884 (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):
10885 Quote AC_FOREACH variable-expansions properly.
10886 The 2003-01-03 obstack.h change also needs merging.
10887 {end of changes requiring merging}
10888
10889 * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
10890 m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
10891 m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
10892 m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
10893 m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
10894 New files, imported from gnulib.
10895 * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
10896 above.
10897
10898 * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
10899 m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
10900 gnulib sources.
10901
10902 * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
10903 Add.
10904 (gl_ERROR): New, replacing jm_PREREQ_ERROR.
10905 (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
10906 (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
10907 (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
10908 (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
10909 (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
10910 (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
10911 (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
10912 (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
10913 (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
10914 (jm_PREREQ_ARGMATCH): Remove.
10915 (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
10916 * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
10917
10918 * src/system.h: Include <stdbool.h> unconditionally.
10919
10920 * lib/bbitset.h: Include <limits.h> unconditionally. We have been
10921 assuming at least C89 in the bitset code for some time now.
10922
10923 2003-03-03 Akim Demaille <akim@epita.fr>
10924
10925 * ro.po: New.
10926
10927 2003-03-02 Akim Demaille <akim@epita.fr>
10928
10929 * doc/bison.texinfo (Table of Symbols): Reactivate the
10930 documentation for %lex-param, and %parse-param.
10931
10932 2003-03-02 Akim Demaille <akim@epita.fr>
10933
10934 * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
10935 generate verbose error messages.
10936 Use the number of tokens as an upper bound in yytname, as it
10937 cannot be a non terminal.
10938
10939 2003-03-02 Akim Demaille <akim@epita.fr>
10940
10941 * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
10942 message.
10943
10944 2003-03-02 Akim Demaille <akim@epita.fr>
10945
10946 * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
10947 Use them to exercise yycheck overrun.
10948 Based on Andrew Suffield's grammar.
10949
10950 2003-03-02 Akim Demaille <akim@epita.fr>
10951
10952 Create tests/local.at for Bison generic testing macros.
10953
10954 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
10955 * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
10956 This new file.
10957 * tests/calc.at (AT_CHECK_CALC): Adjust.
10958 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
10959 (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...
10960 * tests/local.at: here.
10961 (AT_COMPILE_CXX): Tags the tests using it as c++.
10962 Ignore the test if CXX is not functional.
10963
10964 2003-03-01 Paul Eggert <eggert@twinsun.com>
10965
10966 * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
10967 not loc->end, since loc->end might contain garbage and this leads
10968 to undefined behavior on some platforms.
10969 (id_loc, token_start): Use (IF_LINTed) initial values that do not
10970 depend on *loc, so that the reader doesn't give the the false
10971 impression that *loc is initialized.
10972 (<INITIAL>"%%"): Do not bother setting code_start, since its value
10973 does not survive the return.
10974
10975 2003-03-01 Akim Demaille <akim@epita.fr>
10976
10977 * src/scan-gram.l (code_start): Always initialize it when entering
10978 into yylex, as SC_EPILOGUE is activated *before* the corresponding
10979 yylex invocation. An alternative would be making it static, but
10980 then it starts with the second %%'s beginning, instead of its end.
10981
10982 2003-02-28 Paul Eggert <eggert@twinsun.com>
10983
10984 * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
10985 around a UnixWare 7.1.1 porting bug reported by John Hughes in
10986 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
10987
10988 2003-02-26 Paul Eggert <eggert@twinsun.com>
10989
10990 * README: Mention compiler bug in Sun Forte Developer 6 update 2.
10991 Remove Sequent/Pyramid discussion (nobody uses them any more).
10992 Merge VMS and MS-DOS discussion; these ports may well be dead
10993 but let's keep mentioning them for now. Put <> around email
10994 addresses. Add copyright notice.
10995
10996 2003-02-24 Paul Eggert <eggert@twinsun.com>
10997
10998 * data/glr.c (yy_reduce_print): yylineno -> yylno,
10999 to avoid collision with flex use of yylineno.
11000 Problem reported by Bruce Lilly in
11001 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00016.html>.
11002 * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Likewise.
11003 * data/yacc.c (yy_reduce_print): Likewise.
11004

11006
11007 2003-02-21 Akim Demaille <akim@epita.fr>
11008
11009 * data/lalr1.cc: Use temporary variables instead of casts to
11010 change integer types.
11011 Suggested by Paul Eggert.
11012
11013 2003-02-21 Akim Demaille <akim@epita.fr>
11014
11015 * doc/bison.texinfo: Use "location" consistently to refer to @n,
11016 to avoid confusions with lalr1.cc's notion of Position.
11017 Suggested by Paul Eggert.
11018
11019 2003-02-20 Akim Demaille <akim@epita.fr>
11020
11021 * data/lalr1.cc (position.hh): Make sure "columns" never pushes
11022 before initial_columns.
11023 (location.hh): Use consistent variable names when defining the
11024 operator<<.
11025 Use "last" so that we subtract from Positions, not from unsigned.
11026
11027 2003-02-20 Akim Demaille <akim@epita.fr>
11028
11029 * data/lalr1.cc (position.hh): New subfile, including the extended
11030 and Doxygen'ed documentation of class Position.
11031 (location.hh): Use it.
11032 Document a` la Doxygen.
11033 With the help of Benoit Perrot.
11034
11035 2003-02-20 Akim Demaille <akim@epita.fr>
11036
11037 * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
11038 AT_YACC_IF.
11039 Redefine AT_YYERROR_SEES_LOC_IF using it.
11040 (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
11041 not defined.
11042 Don't use the location in yy::Parser::error_ and
11043 yy::Parser::print_ when not %locations.
11044 Activate more lalr1.cc tests.
11045
11046 2003-02-19 Akim Demaille <akim@epita.fr>
11047
11048 * data/lalr1.cc: When displaying a line number, be sure to make it
11049 an int.
11050
11051 2003-02-19 Akim Demaille <akim@epita.fr>
11052
11053 * data/lalr1.cc (b4_stack_depth_init, yy::Parser::initdepth_):
11054 Remove, useless.
11055 (YYABORT, YYACCEPT, YYERROR): New.

11058 2003-02-19 Akim Demaille <akim@epita.fr>
11059
11060 * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
11061 error recovery, mixing with/without pops and discarding of the
11062 lookahead.
11063 Exercise YYERROR.
11064 Disable the lalr1.cc tests as currently it doesn't support YYERROR.
11065
11066 2003-02-17 Paul Eggert <eggert@twinsun.com>
11067
11068 * tests/atlocal.in (LDFLAGS, LIBS): New vars.
11069 * tests/testsuite.at (AT_COMPILE): Use them.
11070 This fixes the testsuite problem reported by Robert Lentz in
11071 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
11072
11073 2003-02-12 Paul Eggert <eggert@twinsun.com>
11074
11075 * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:
11076 Avoid subscript error in yycheck. Bug reported by Andrew Suffield in
11077 <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00003.html>.
11078 * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
11079 Check for malloc failure, for consistency with yacc.c.
11080 (yytname_size): Remove, for consistency with yacc.c.
11081
11082 The bug still remains in data/lalr1.cc, as I didn't have time
11083 to fix it there.
11084
11085 2003-02-06 Akim Demaille <akim@epita.fr>
11086
11087 * configure.ac (GXX): Rename as...
11088 (CXX): this, to keep the original Autoconf semantics.
11089 Require 2.57.
11090 * data/lalr1.cc: Fix b4_copyright invocations.
11091 If YYDEBUG is not defined, don't depend upon name_ being defined.
11092 (location.hh): Include string and iostream.
11093 (Position::filename): New member.
11094 (Position::Position ()): New.
11095 (operator<< (Position)): New.
11096 (operator- (Position, int)): New.
11097 (Location::first, Location::last): Rename as...
11098 (Location::begin, Location::end): these, to mock the conventional
11099 iterator names.
11100 (operator<< (Location)): New.
11101 * tests/atlocal.in (CXX): New.
11102 * tests/testsuite.at (AT_COMPILE_CXX): New.
11103 * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
11104 locations in a more synthetic way.
11105 (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
11106 lalr1.cc is used.
11107 Adjust the C locations to match those from Emacs: first column is
11108 column 0.
11109 Change all the expected results.
11110 Conform to the GCS: simplify the locations when applicable.
11111 (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
11112 (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace
11113 these CPP macros with the m4 macros new defined by...
11114 (AT_CHECK_PUSHDEFS): this, i.e.:
11115 (AT_LALR1_CC_IF, AT_PURE_LEX_IF, AT_LOC, AT_VAL, AT_LEX_FORMALS)
11116 (AT_LEX_ARGS, AT_USE_LEX_ARGS, AT_LEX_PRE_FORMALS, AT_LEX_PRE_ARGS)
11117 New macros.
11118 (AT_CHECK_POPDEFS): Undefine them.
11119 (AT_CHECK_CALC_LALR1_CC): New.
11120 Use it for the first lalr1.cc test.
11121
11122 2003-02-04 Akim Demaille <akim@epita.fr>
11123
11124 * data/lalr1.cc (YYLLOC_DEFAULT): Fix its definition: be based on
11125 Location as is defined.
11126
11127 2003-02-04 Akim Demaille <akim@epita.fr>
11128
11129 * data/lalr1.cc: If YYDEBUG is not defined, don't depend upon
11130 name_ being defined.
11131
11132 2003-02-03 Paul Eggert <eggert@twinsun.com>
11133
11134 * src/gram.h (start_symbol): Remove unused decl.
11135
11136 Use more-consistent naming conventions for local vars.
11137
11138 * src/derives.c (derives_compute): Change type of local var from
11139 int to rule_number.
11140 * src/gram.c (grammar_rules_partial_print): Likewise.
11141 * src/print.c (print_core): Likewise.
11142 * src/reduce.c (reduce_grammar_tables): Likewise.
11143
11144 * src/gram.c (grammar_dump): Change name of item_number *
11145 local var from r to rp.
11146 * src/nullable.c (nullable_compute): Likewise.
11147
11148 * src/gram.h (ISTOKEN, ISVAR): Use i, not s, for int var.
11149
11150 * src/gram.h (symbol_number_as_item_number): Use sym, not s,
11151 for symbol or symbol_number var.
11152 * src/reader.c (grammar_start_symbol_set): Likewise.
11153 * src/reader.h (grammar_start_symbol_set, grammar_symbol_append):
11154 Likewise.
11155 * src/state.c (transitions_to): Likewise.
11156 * src/state.h: Likewise.
11157 * src/tables.c (symbol_number_to_vector_number): Likewise.
11158
11159 * src/muscle_tab.h (MUSCLE_OBSTACK_SGROW): Use p, not s, for
11160 char * var.
11161
11162 * src/parse-gram.y (lloc_default): Use loc, not r, for YYLTYPE
11163 var.
11164
11165 * src/scan-gram.l (no_cr_read): Use bytes_read, not s, for size
11166 var.
11167
11168 * src/system.h (xstrndup, strchr, strspn, strnlen, memchr, memrchr):
11169 Use str, not s, for char * var. Use ch, not c, for character var.
11170 Use size for size var.
11171
11172 * src/uniqstr.c (uniqstr_new, uniqstr_assert): Use str, not s, for
11173 char * var.
11174 (uniqstr_print, uniqst_print_processor): Use ustr, not s, for
11175 uniqstr var.
11176 * src/uniqstr.h: Likewise.
11177

11179 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
11180 get_node_alignment_str, get_arrow_mode_str, get_crossing_type_str,
11181 get_view_str, get_linestyle_str, get_arrowstyle_str): Rename
11182 param to have same name as that of enum, so that we don't use
11183 "s" to stand for a non-state.
11184
11185 2003-02-02 Akim Demaille <akim@epita.fr>
11186
11187 * src/scan-skel.l: Scan more than one inert character per yylex
11188 invocation.
11189
11190 2003-02-01 Paul Eggert <eggert@twinsun.com>
11191
11192 Version 1.875a.
11193
11194 * po/LINGUAS: Add ms.
11195
11196 2003-01-30 Akim Demaille <akim@epita.fr>
11197
11198 * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
11199
11200 2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
11201
11202 * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
11203 of $1.
11204
11205 Changes in response to error report by S. Eken: GLR mode does not
11206 handle negative $ indices or $ indices in embedded rules correctly.
11207 See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
11208
11209 * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
11210 (b4_rhs_location): Ditto.
11211 (yyfill): New function to copy from stack tree into array
11212 incrementally.
11213 (yyuserAction): Modify to allow incremental move of semantic values
11214 to rhs array when in GLR mode.
11215 Define YYFILL to use in user-defined actions to fill semantic array
11216 as needed.
11217 Remove dummy use of yystack, as there is now a guaranteed use.
11218 (yydoAction): Modify to allow incremental move of semantic values
11219 to rhs array when in GLR mode.
11220 (yyresolveAction): Ditto.
11221 (yyglrShiftDefer): Update comment.
11222 (yyresolveStates): Use X == NULL for pointers, not !X.
11223 (yyglrReduce): Ditto.
11224 (yydoAction): Ditto
11225
11226 * tests/glr-regr1.at: Rename to ...
11227 * tests/glr-regression.at: Add new regression test for the problems
11228 described above (adapted from S. Eken).
11229 Update copyright notice.
11230 * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
11231 * tests/Makefile.am: Ditto.
11232
11233 2003-01-28 Paul Eggert <eggert@twinsun.com>
11234
11235 * data/lalr1.cc: Do not use @output_header_name@ unless
11236 b4_defines_flag is set. This fixes two bugs reported by
11237 Tim Van Holder in
11238 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
11239 and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
11240
11241 2003-01-21 Paul Eggert <eggert@twinsun.com>
11242
11243 * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
11244 we don't need to worry about yyerrlab1 being reported as an
11245 "unused label" by non-GCC C compilers. The downside is that if
11246 locations are used then a couple of statements are duplicated each
11247 time YYERROR is invoked, but the upside is that the warnings
11248 should vanish.
11249 (yyerrlab1): Move code to YERROR.
11250 (yyerrlab2): Remove. Change uses back to yyerrlab1.
11251 This reverts some of the 2002-12-27 change.
11252
11253 2003-01-17 Paul Eggert <eggert@twinsun.com>
11254
11255 * src/output.c (symbol_printers_output): Fix typo that led
11256 to core dump. Problem reported by Antonio Rus in
11257 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
11258
11259 2003-01-13 Akim Demaille <akim@epita.fr>,
11260 Quoc Peyrot <chojin@lrde.epita.fr>,
11261 Robert Anisko <anisko_r@lrde.epita.fr>
11262
11263 * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
11264 when the stacks contain one element, as the loop would otherwise
11265 free the last state, and then use the top state (the one we just
11266 popped). This means that the initial elements will not be freed
11267 explicitly, as is the case in yacc.c; it is not a problem, as
11268 these elements have fake values.
11269
11270 2003-01-11 Paul Eggert <eggert@twinsun.com>
11271
11272 * NEWS: %expect-violations are now just warnings, reverting
11273 to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
11274 bootstrapping problem reported by Matthias Klose; see
11275 <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
11276 * src/conflicts.c (conflicts_print): Likewise.
11277 * tests/conflicts.at (%expect not enough, %expect too much,
11278 %expect with reduce conflicts): Likewise.
11279 * doc/bison.texinfo (Expect Decl): Document this. Also mention
11280 that the warning is enabled if the number of conflicts changes
11281 (not necessarily increases).
11282
11283 * src/getargs.c (version): Update copyright year.
11284
11285 2003-01-09 Akim Demaille <akim@epita.fr>
11286
11287 * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
11288
11289 2003-01-08 Paul Eggert <eggert@twinsun.com>
11290
11291 * Makefile.maint (WGETFLAGS):
11292 New macro, containing "-C off" to disable proxy caches.
11293 All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
11294 (rel-check): Use $(WGET) instead of wget.
11295
11296 2003-01-06 Paul Eggert <eggert@twinsun.com>
11297
11298 * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
11299 the GLR paper of Scott, Johnstone and Hussain.
11300
11301 2003-01-04 Paul Eggert <eggert@twinsun.com>
11302
11303 * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
11304 (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
11305 * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
11306 (EXTRA_LIBRARIES): New var, for liby.a.
11307 * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
11308 (EXTRA_SCRIPTS): New var, for yacc.
11309
11310 * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
11311 since GNU C++ (as of 3.2.1) does not allow attributes on labels.
11312 Problem reported by Nelson H. F. Beebe.
11313
11314 2003-01-03 Paul Eggert <eggert@twinsun.com>
11315
11316 * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
11317 (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
11318 when compiling Bison 1.875's `bitset bset = obstack_alloc
11319 (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
11320
11321 * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
11322 ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
11323 grow to a huge size with typical invocation.
11324
11325 * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
11326 Use the pattern recommended by Autoconf 2.57, except also protect
11327 against double-definition.
11328 * src/system.h: Likewise.
11329 Portability issues reported by Nelson H. F. Beebe.
11330
11331 * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
11332 All uses changed. Provide a definition in both C and C++.
11333 (yytrue, yyfalse): Define even if defined (__cplusplus).
11334
11335 * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
11336 Reported by Nelson H. F. Beebe.
11337
11338 * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
11339
11340 2003-01-02 Paul Eggert <eggert@twinsun.com>
11341
11342 * data/yacc.c (yyerrlab1): Append `;' after attribute, to
11343 pacify the buggy "smart preprocessor" in MacOS 10.2.3.
11344 Bug reported by Nelson H. F. Beebe.
11345
11346 2003-01-01 Paul Eggert <eggert@twinsun.com>
11347
11348 * Version 1.875.
11349
11350 2002-12-30 Paul Eggert <eggert@twinsun.com>
11351
11352 * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
11353 Moved here from...
11354 (<INITIAL>","): Here. This causes stray "," to be treated
11355 more uniformly.
11356
11357 * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
11358 last brace in braced code when not in Yacc mode, for compatibility
11359 with Bison 1.35. This resurrects the 2001-12-15 patch to
11360 src/reader.c.
11361
11362 * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
11363 yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
11364
11365 2002-12-28 Paul Eggert <eggert@twinsun.com>
11366
11367 * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
11368 that of SYM's type. This fixes Debian bug 168069, reported by
11369 Thomas Olsson.
11370
11371 2002-12-28 Paul Eggert <eggert@twinsun.com>
11372
11373 Version 1.75f.
11374
11375 Switch back to the Yacc style of conflict reports, undoing some
11376 of the 2002-07-30 change.
11377 * doc/bison.texinfo (Understanding): Use Yacc style for
11378 conflict reports. Also, use new way of locating rules.
11379 * src/conflicts.c (conflict_report):
11380 Renamed from conflict_report_yacc, removing the old
11381 'conflict_report'. Translate the entire conflict report at once,
11382 so that we don't assume that "," has the same interpretation in
11383 all languages.
11384 (conflicts_output): Use Yacc-style conflict report for each state,
11385 instead of our more-complicated style.
11386 (conflicts_print): Use Yacc-style conflict report, except print
11387 the input file name when not emulating Yacc.
11388 * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
11389 Conflicted Reduction, %expect not enough, %expect too much,
11390 %expect with reduce conflicts): Switch to Yacc-style conflict reports.
11391 * tests/existing.at (GNU Cim Grammar): Likewise.
11392 * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
11393
11394 * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
11395 fatal): Don't invoke fflush; it's not needed and it might even be
11396 harmful for stdout, as stdout might not be open.
11397 * src/reduce.c (reduce_print): Likewise.
11398
11399 2002-12-27 Paul Eggert <eggert@twinsun.com>
11400
11401 Fix a bug where error locations were not being recorded correctly.
11402 This problem was originally reported by Paul Hilfinger in
11403 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
11404
11405 * data/yacc.c (yyparse): New local var yylerrsp, to record the
11406 top of the location stack's error locations.
11407 (yyerrlab): Set it. When discarding a token, push its location
11408 onto yylerrsp so that we don't lose track of the error's end.
11409 (yyerrlab1): Now is only the target of YYERROR, so that we can
11410 properly record the location of the action that failed. For GCC
11411 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
11412 GCC warning about yyerrlab1 being unused if YYERROR is unused.
11413 (yyerrlab2): New label, which yyerrlab now falls through to.
11414 Compute the error's location by applying YYLLOC_DEFAULT to
11415 the locations of all the symbols that went into the error.
11416 * doc/bison.texinfo (Location Default Action): Mention that
11417 YYLLOC_DEFAULT is also invoked for syntax errors.
11418 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
11419 Error locations include the locations of all the tokens that were
11420 discarded, not just the last token.
11421
11422 2002-12-26 Paul Eggert <eggert@twinsun.com>
11423
11424 * src/files.c: Include quote.h.
11425 (compute_output_file_names): Warn if we detect conflicting
11426 outputs to the same file. This should catch the misunderstanding
11427 exemplified by Debian Bug 165349, reported by Bruce Stephens..
11428
11429 * src/conflicts.c (conflicts_print): If the user specifies
11430 "%expect N", report an error if there are any reduce/reduce
11431 conflicts. This is what the manual says should happen.
11432 This fixes Debian bug 130890, reported by Anthony DeRobertis.
11433 * tests/conflicts.at (%expect with reduce conflicts): New test.
11434
11435 Don't use m4_include on relative file names, as it doesn't work as
11436 desired if there happens to be a file with that name under ".".
11437
11438 * m4sugar/version.m4: Remove; it was included but it wasn't used.
11439 * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
11440 * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
11441 * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
11442 * src/output.c (output_skeleton): Use full path names when
11443 specifying a file to include; don't rely on include path, as
11444 it's unreliable when the working file contains a file with
11445 that name.
11446
11447 2002-12-25 Paul Eggert <eggert@twinsun.com>
11448
11449 Remove obsolete references to bison.simple and bison.hairy.
11450 Problem mentioned by Aubin Mahe in
11451 <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
11452 * data/glr.c: Comment fix.
11453 * doc/bison.1: Remove references. Also, mention "yacc".
11454
11455 * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
11456 with -g option.
11457
11458 * src/parse-gram.y (declaration): Use enum "report_states" rather
11459 than its numeric value 1.
11460
11461 * src/scan-skel.l ("@output ".*\n): Close any old yyout before
11462 opening a new one. This fixes Debian bug 165349, reported by
11463 Bruce Stephens.
11464
11465 2002-12-24 Paul Eggert <eggert@twinsun.com>
11466
11467 Version 1.75e.
11468
11469 * Makefile.maint (cvs-update): Don't assume that the shell
11470 supports $(...), as Solaris sh doesn't.
11471
11472 * src/parse-gram.y (lloc_default): Remove test for empty
11473 nonterminals at the end, since it didn't change the result.
11474
11475 2002-12-24 Paul Eggert <eggert@twinsun.com>
11476
11477 If the user does not define YYSTYPE as a macro, Bison now declares it
11478 using typedef instead of defining it as a macro. POSIX requires this.
11479 For consistency, YYLTYPE is also declared instead of defined.
11480
11481 %union directives can now have a tag before the `{', e.g., the
11482 directive `%union foo {...}' now generates the C code
11483 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
11484 The default union tag is `YYSTYPE', for compatibility with Solaris 9
11485 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
11486 instead of `yyltype'.
11487
11488 `yystype' and `yyltype' are now obsolescent macros instead of being
11489 typedefs or tags; they are no longer documented and will be
11490 withdrawn in a future release.
11491
11492 * data/glr.c (b4_location_type): Remove.
11493 (YYSTYPE): Renamed from yystype.
11494 (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
11495 (struct YYLTYPE): Renamed from struct yyltype.
11496 (YYLTYPE): Renamed from yyltype.
11497 (yyltype, yystype): New (and obsolescent) macros,
11498 for backward compatibility.
11499 * data/yacc.c: Likewise.
11500
11501 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
11502 does not specify a union tag. This is for compatibility with
11503 Solaris 9 yacc.
11504
11505 * src/parse-gram.y (add_param): 2nd arg is now char * not char
11506 const *, since it is now modified by stripping surrounding { }.
11507 (current_braced_code): Remove.
11508 (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
11509 PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
11510 trailing " {...}". Now of type <chars>.
11511 (grammar_declaration): Adjust to bundled tokens.
11512 (code_content): Remove; stripping is now done by add_param.
11513 (print_token_value): Print contents of bundled tokens.
11514 (token_name): New function.
11515
11516 * src/reader.h (braced_code, current_braced_code): Remove.
11517 (token_name): New decl.
11518
11519 * src/scan-gram.l (handle_dollar, handle_at): Now takes int
11520 token_type, not braced_code code_kind. All uses changed.
11521 (SC_PRE_CODE): New state, for scanning after a keyword that
11522 has (or usually has) an immediately-following braced code.
11523 (token_type): New local var, to keep track of which token type
11524 to return when scanning braced code.
11525 (<INITIAL>"%destructor", <INITIAL>"%lex-param",
11526 <INITIAL>"%parse-param", <INITIAL>"%printer",
11527 <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
11528 instead of returning a token type immediately.
11529 (<INITIAL>"{"): Set token type.
11530 (<SC_BRACED_CODE>"}"): Use it.
11531 (handle_action_dollar, handle_action_at): Now returns bool
11532 indicating success. Fail if ! current_rule; this prevents a core dump.
11533 (handle_symbol_code_dollar, handle_symbol_code_at):
11534 Remove; merge body into caller.
11535 (handle_dollar, handle_at): Complain in invalid contexts.
11536

11541
11542 * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
11543 Reporting, Table of Symbols): Omit mentions of %lex-param and
11544 %parse-param from the documentation for now.

11547
11548 Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
11549 GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
11550 lookahead symbol, and which sets yychar in parser actions) and it
11551 disagreed with the Bison documentation. Bug
11552 reported by Andrew Walrond.
11553
11554 * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
11555 as the caller now does that.
11556 (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
11557 (YYEMPTY): Parenthesize right hand side, since others use it.
11558 (yyparse): Don't assume that our generated code is the only code
11559 that sets yychar.
11560
11561 2002-12-13 Paul Eggert <eggert@twinsun.com>
11562
11563 Version 1.75d.

11573
11574 * src/getargs.c (__GNU_LIBRARY__) [lint]: Define to work around

11591
11592 2002-12-12 Paul Eggert <eggert@twinsun.com>
11593
11594 Remove unportable casts and storage allocation tricks.
11595 While we're at it, remove almost all casts, since they
11596 usually aren't needed and are a sign of trouble.
11597
11598 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
11599
11600 * src/derives.c (derives_compute): Do not subtract NTOKENS from
11601 the pointer DSET returned by malloc; this isn't portable.
11602 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
11603 Similarly for DERIVES.
11604 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
11605 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
11606 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
11607
11608 * src/derives.c (derives_compute): Do not bother invoking
11609 int_of_rule_number, since rule numbers are integers.
11610
11611 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
11612 rather than XMALLOC (char, N).
11613
11614 * src/files.c (filename_split): Rewrite to avoid cast.
11615
11616 * src/gram.h (symbol_number_as_item_number,
11617 item_number_as_symbol_number, rule_number_as_item_number,
11618 item_number_as_rule_number):
11619 Now inline functions rather than macros, to avoid casts.
11620 * src/state.h (state_number_as_int): Likewise.
11621 * src/tables.c (state_number_to_vector_number,
11622 symbol_number_to_vector_number): Likewise.
11623
11624 * src/gram.h (int_of_rule_number): Remove; no longer used.
11625
11626 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
11627 since the resulting storage is always stored into.
11628
11629 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
11630 where it's needed.
11631
11632 * src/muscle_tab.c (muscle_m4_output):
11633 Now inline. Return bool, not int.
11634 * src/state.c (state_compare): Likewise.

11638 Likewise.
11639 * src/uniqstr.c (uniqstr_print): Likewise.
11640 * src/muscle_tab.c (muscle_m4_output_processor):
11641 New function, to avoid casts.
11642 * src/state.c (state_comparator, stage_hasher): Likewise.
11643 * src/symtab.c (symbol_check_defined_processor,
11644 symbol_check_alias_consistency_processor, symbol_pack_processor,
11645 symbol_translation_processor, hash_symbol_comparator,
11646 hash_symbol_hasher): Likewise.
11647 * src/uniqstr.c (uniqstr_print_processor): Likewise.
11648 * src/muscle_tab.c (muscles_m4_output):
11649 Use new functions instead of casting old functions unportably.
11650 * src/state.c (state_hash_new): Likewise.
11651 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
11652 symbols_token_translations_init):
11653 Likewise.
11654 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
11655
11656 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
11657 var instead of casting to long, to avoid casts.
11658 (prepare_states): Use MALLOC rather than alloca, so that we don't
11659 have to worry about alloca.
11660 * src/state.c (state_hash_lookup): Likewise.
11661
11662 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
11663 local var instead of casting to unsigned char, to avoid casts.
11664
11665 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
11666 STATE_ALLOC): Remove.
11667 (transitions_new, errs_new, reductions_new, state_new): Use malloc
11668 rather than calloc, and use offsetof to avoid allocating slightly
11669 too much storage.
11670 (state_new): Initialize all members.
11671
11672 * src/state.c (state_hash): Use unsigned accumulator, not signed.
11673
11674 * src/symtab.c (symbol_free): Remove; unused.
11675 (symbol_get): Remove cast in lhs of assignment.
11676 (symbols_do): Now static. Accept generic arguments, not
11677 hashing-related ones.
11678
11679 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
11680 (symbol_processor): Remove.
11681 (symbols_do): Remove decl; now static.
11682
11683 * src/system.h (alloca): Remove; decl no longer needed.
11684 (<stddef.h>): Include, for offsetof.
11685 (<inttypes.>, <stdint.h>): Include if available.
11686 (uintptr_t): New type, if system lacks it.
11687 (CALLOC, MALLOC, REALLOC): New macros.
11688 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
11689 new macros.
11690
11691 * src/tables.c (table_size): Now int, to pacify GCC.
11692 (table_grow, table_ninf_remap): Use signed table size.
11693 (save_row): Don't bother initializing locals when not needed.
11694 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
11695 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
11696
11697 * src/vcg.h: Correct misspellings.
11698
11699 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.
11700
11701
11702 * src/getargs.c (getargs): Don't assume EOF == -1.
11703
11704 2002-12-09 Paul Eggert <eggert@twinsun.com>
11705
11706 Change identifier spellings to avoid collisions with names
11707 that are reserved by POSIX.
11708
11709 Don't use names ending in _t, since POSIX reserves them.
11710 For consistency, remove _e and _s endings -- they're weren't
11711 needed to remove ambiguity. All uses changed.
11712 * src/uniqstr.h (uniqstr): Renamed from uniqstr_t, which in
11713 turn was just renamed from struniq_t.
11714 * src/uniqstr.c (uniqstr_processor): Renamed from struniq_processor,
11715 which in turn was just renamed from struniq_processor_t.
11716 (hash_compare_uniqstr): Renamed from hash_compare_struniq, which
11717 in turn was renamed from hash_compare_struniq_t.

11787 value_t_as_yystype -> value_as_yystype.
11788
11789 Don't include <errno.h> in the mainstream code, since it
11790 reserves E[A-Z0-9]* and we want to use symbols like 'EQUALS'.
11791 * lib/get-errno.c, lib/get-errno.h: New files.
11792 * lib/Makefile.am (libbison_a_SOURCES): Add get-errno.h,

11802 (TAB_EXT): Renamed from EXT_TAB.
11803 (OUTPUT_EXT): Renamed from EXT_OUTPUT.
11804
11805 Avoid str[a-z]*, since <string.h> reserves that name space.
11806 Change all instances of "struniq" in names to "uniqstr", and
11807 likewise for "STRUNIQ" and "UNIQSTR".
11808 * src/uniqstr.c: Renamed from src/struniq.c.
11809 * src/uniqstr.h: Renamed from src/struniq.h.

11821 (N_EXPAND): Renamed from N_STRETCH.
11822
11823 Avoid *_MAX and *_MIN, since <limits.h> reserves that name space.
11824 * data/yacc.c (YYSTACK_GAP_MAXIMUM): Renamed from YYSTACK_GAP_MAX.
11825 * src/gram.h (ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
11826 Remove; unused.

11829 * src/symtab.h (SYMBOL_NUMBER_MAXIMUM): Renamed from SYMBOL_NUMBER_MAX.

11835 Unnecessary casts removed from above defines.
11836
11837

11843
11844 * lib/timevar.c (timevar_report): Renamed from time_report,
11845 for consistency with other names.
11846 * lib/timevar.h (timevar_report): New decl.
11847 * src/system.h (time_report): Remove; decl is now in lib/timevar.h.
11848
11849
11850 Sort include-file uses.
11851
11852 Reorder all include files under src to be in the order "system.h".
11853 then the ../lib include files in angle brackets (alphabetized),
11854 then the . include files in double-quotes (alphabetized). Fix
11855 dependency breakages encountered in this process, as follows:
11856 * src/closure.h, src/derives.h, src/state.h: Include "gram.h".
11857 * src/complain.c: Don't include stdlib.h, string.h _LIBC stuff.
11858 * src/state.h: Include "symtab.h".
11859
11860 2002-12-08 Paul Eggert <eggert@twinsun.com>
11861
11862 * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
11863 since this causes problems when __file__ contains character
11864 sequences like "@" that are treated specially by src/scan-skel.l.
11865 Instead, just use the file's basename. This fixes the bug
11866 reported by Martin Mokrejs in
11867 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.
11868

11870
11871 Add support for rules that do not have trailing semicolons, as
11872 POSIX requires. Improve the quality of locations in Bison
11873 diagnostics.
11874
11875 * src/location.c: Include <quotearg.h>.
11876 (empty_location): Now const.
11877 (location_print): New function. Follow the recommendation of the
11878 GNU Coding Standards for locations that span file boundaries.
11879 * src/location.h: Do not include <quotearg.h>; no longer needed.
11880 (boundary): New type.
11881 (location_t): Use it. This allows locations to span file boundaries.
11882 All member uses changed: file -> start.file or end.file (as needed),
11883 first_line -> start.line, first_column -> start.column,
11884 last_line -> end.line, last_column -> end.column.
11885 (equal_boundaries): New function.
11886 (LOCATION_RESET, LOCATION_STEP): Remove.
11887 (LOCATION_PRINT): Remove. All callers changed to use location_print.

11905 rolling our own.
11906 * src/scan-gram.l (YY_USER_INIT): Initialize scanner_cursor instead
11907 of *loc.
11908 (STEP): Remove. No longer needed, now that adjust_location does
11909 the work. All uses removed.
11910 (scanner_cursor): New var.
11911 (adjust_location): Renamed from extend_location. It now sets
11912 *loc and adjusts the scanner cursor. All uses changed.
11913 Don't bother testing for CR.
11914 (handle_syncline): Remove location arg; now updates scanner cursor.
11915 All callers changed.
11916 (unexpected_end_of_file): Now accepts start boundary of token or
11917 comment, not location. All callers changed. Update scanner cursor,
11918 not the location.
11919 (SC_AFTER_IDENTIFIER): New state.
11920 (context_state): Renamed from c_context. All uses changed.
11921 (id_loc, code_start, token_start): New local vars.
11922 (<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
11923 processing of Yacc white space and equivalents here.
11924 (<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
11925 instead of returning ID immediately, since we need to search for
11926 a subsequent colon.
11927 (<INITIAL>"'", "\""): Save token_start.
11928 (<INITIAL>"%{", "{", "%%"): Save code_start.
11929 (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
11930 (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
11931 BEGIN context_state at end, not INITIAL.
11932 (<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
11933 <SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
11934 Return correct token start.
11935 (<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
11936 the start of a character, string or multiline comment is found.
11937 * tests/conflicts.at (S/R in initial, Defaulted Conflicted
11938 Reduction): Adjust reported locations to match the more-precise
11939 results now expected.
11940 * tests/input.at (Invalid $n, Invalid @n, Type Clashes): Likewise.
11941 * tests/reduce.at (Useless Rules, Reduced Automaton,
11942 Underivable Rules): Likewise.
11943 * tests/regression.at (Invalid inputs): No longer `expecting ";"
11944 or "|"' now that so many other tokens are allowed by the new grammar.
11945
11946 * src/complain.h (current_file): Remove duplicate decl;
11947 current_file is now owned by files.h.
11948 * src/complain.c, src/scan-gram.l: Include files.h.
11949
11950 2002-12-06 Paul Eggert <eggert@twinsun.com>
11951
11952 * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
11953 promotes to int; it might be unsigned int.
11954 * data/yacc.c (yy_reduce_print): Likewise.
11955
11956 * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
11957 be #defined in the prologue, not in the Bison declarations.
11958 This fixes Debian Bug 102878, reported by Shaul Karl.
11959
11960 2002-12-02 Paul Eggert <eggert@twinsun.com>
11961
11962 * configure.ac (AC_REPLACE_FUNCS): Add strtoul.
11963 * lib/strtoul.c: New file, from gnulib.
11964 This fixes a porting bug reported by Peter Klein in
11965 <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00000.html>.
11966
11967 2002-11-30 Paul Eggert <eggert@twinsun.com>
11968
11969 * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
11970 and put only a forward declaration in the prologue. This is for
11971 consistency with the other scanner helper functions.
11972
11973 Type clashes now generate warnings, not errors, since it
11974 appears that POSIX may allow some grammars with type clashes.
11975 * src/reader.c (grammar_current_rule_check): Warn about
11976 type clashes instead of complaining.
11977 * tests/input.at (Type Clashes): Expect warnings, not complaints.
11978
11979 Add Yacc library, since POSIX requires it.
11980 * doc/bison.texinfo (Yacc Library): New node. Regenerate top menu.
11981 * lib/Makefile.am (lib_LIBRARIES, liby_a_SOURCES): New macros.
11982 * lib/main.c, lib/yyerror.c: New files.
11983
11984 gram_error can be static; it need not be extern.
11985 * src/reader.h (gram_error): Remove decl.
11986 * src/parse-gram.y (gram_error): Now static. Add static decl.
11987 (print_token_value): Omit parameter names from forward decl,
11988 for consistency.
11989
11990 2002-11-29 Paul Eggert <eggert@twinsun.com>
11991
11992 * doc/bison.texinfo: Emphasize that yylex and yyerror must
11993 be declared before being used. E.g., one should typically
11994 declare them in the prologue. Use GNU coding style in examples.
11995 Put "const" consistently after the type it modifies. Mention
11996 that C99 supports "inline". Mention that yyerror traditionally
11997 returns "int".
11998
11999 %parse-param and %lex-param now take just one argument, the
12000 declaration; the argument name is deduced from the declaration.
12001
12002 * doc/bison.texinfo (Parser Function, Pure Calling, Error
12003 Reporting, Table of Symbols): Document this.
12004 * src/parse-gram.y (add_param): New function.
12005 (COMMA): Remove.
12006 (declaration): Implement new rule for %parse-param and %lex-param.
12007 * src/scan-gram.l: "," now elicits a warning, rather than being
12008 a token; this is more compatible with byacc.
12009 * tests/calc.at (Simple LALR Calculator): Adopt new convention.
12010
12011 2002-11-27 Paul Eggert <eggert@twinsun.com>
12012
12013 Rename identifiers to avoid real and potential collisions.
12014
12015 * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,
12016 to avoid collision with lex macro described by Bruce Lilly in
12017 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
12018 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise.
12019 * doc/bison.texinfo (Prologue, Tracing): yyprint -> print_token_value.
12020 * src/parse-gram.y (print_token_value): Renamed from yyprint.
12021 All uses changed.
12022 (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
12023 The name "yycontrol" violates the name space rules, and this stuff
12024 wasn't being used anyway.
12025 (input): Remove action; this stuff wasn't being used.
12026 (gram_error): Rename local variable yylloc -> loc.
12027 * src/reader.h (struct gram_control_s, gram_control_t): Remove.
12028 (YY_DECL): Don't use "yy" at start of local variables.
12029 All uses changed, e.g., yylloc -> loc.
12030 * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
12031 (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
12032 (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
12033 (STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
12034
12035 * src/parse-gram.y (gram_error): loc is now const *.
12036 * src/reader.h (gram_error): Likewise.
12037
12038 2002-11-24 Paul Eggert <eggert@twinsun.com>
12039
12040 Version 1.75c.
12041
12042 * tests/actions.at (Actions after errors): Use an output format
12043 more similar to that of the Printers and Destructors test.
12044 Test the position of the ';' token too.
12045 (Printers and Destructors): Likewise.
12046 (Printers and Destructors: %glr-parser): Remove for now, to avoid
12047 unnecessarily alarming people when the test fails.
12048
12049 * data/yacc.c (yyerrlab1): Move this label down, so that the
12050 parser does not discard the lookahead token if the user code
12051 invokes YYERROR. This change is required for POSIX conformance.
12052
12053 * lib/error.c: Sync with gnulib.
12054
12055 2002-11-22 Paul Eggert <eggert@twinsun.com>
12056
12057 * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.
12058 * lib/mbswidth.c, lib/mbswidth.h: Likewise.
12059 * lib/xmalloc.c: Likewise.
12060
12061 2002-11-20 Paul Eggert <eggert@twinsun.com>
12062
12063 * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
12064
12065 2002-11-20 Paul Eggert <eggert@twinsun.com>
12066
12067 Avoid use of <assert.h>, as the GNU Coding Standards hint that one
12068 should use `if (! x) abort ();' rather than `assert (x);', and
12069 anyway it's one less thing to worry about configuring.
12070
12071 * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
12072 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
12073 and replace all instances of assert with abort.
12074 * tests/calc.at (_AT_DATA_CALC_Y): Likewise.
12075 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Likewise.
12076

12080 hash_find_entry, hash_rehash, hash_insert): Likewise.
12081 * src/conflicts.c (resolve_sr_conflict): Likewise.
12082 * src/lalr.c (set_goto_map, map_goto): Likewise.
12083 * src/nullable.c (nullable_compute): Likewise.
12084 * src/output.c (prepare_rules, token_definitions_output): Likewise.
12085 * src/reader.c (packgram, reader): Likewise.
12086 * src/state.c (state_new, state_free, state_transitions_set,
12087 state_reduction_find): Likewise.
12088 * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
12089 symbol_pack): Likewise.
12090 * src/tables.c (conflict_row, pack_vector): Likewise.
12091 * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
12092 get_layoutalgorithm_str, get_decision_str, get_orientation_str,
12093 get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
12094 get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
12095
12096 * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.
12097 (ARGMATCH_CONSTRAINT): New macro.
12098 (ARGMATCH_ASSERT): Use it.
12099
12100 * src/system.h (verify): New macro.
12101 * src/getargs.c (trace_argmatch, report_argmatch): Use verify
12102 rather than assert.
12103 * src/tables.c (tables_generate): Likewise.
12104
12105 * src/struniq.c (struniq_assert): Now returns void, and aborts
12106 if the assertion is false.
12107 (struniq_assert_p): Remove.
12108 * src/struniq.h: Likewise.
12109
12110 2002-11-18 Paul Eggert <eggert@twinsun.com>
12111
12112 * data/glr.c (yygetLRActions): Replace `yyindex' with
12113 `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
12114 This fixes the regression with Sun ONE Studio 7 cc that I reported in
12115 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00077.html>.
12116
12117 2002-11-18 Akim Demaille <akim@epita.fr>
12118
12119 * doc/bison.texinfo (Tracing): `yyprint' shouldn't prepend a
12120 space.
12121 From Tim Van Holder.
12122
12123 2002-11-17 Paul Eggert <eggert@twinsun.com>
12124
12125 Pacify Sun ONE Studio 7 lint. Also, rename "ParseError"
12126 to "SyntaxError" for consistency with my 2002-11-15 change.
12127
12128 * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
12129 not define to {}, since this breaks the common use of `YYDPRINTF
12130 ((...));' if a single statement is desired (e.g. before `else').
12131 Work around GCC warnings by surrounding corresponding calls with
12132 {} if needed.
12133 (yyhasResolvedValue): Remove unused function.
12134 (yymergeOptionSets, yyresolvStack): Use `continue;' for empty
12135 loop body.
12136 (yyreportSyntaxError): Renamed from yyreportParseError.
12137 (yyrecoverSyntaxError): Renamed from yyrecoverParseError.
12138 All uses changed.
12139 * tests/calc.at (_AT_DATA_CALC_Y): Make vars static instead of
12140 extern when possible. Remove unused initializations.
12141
12142 2002-11-16 Akim Demaille <akim@epita.fr>
12143
12144 Augment the similarity between GLR and LALR traces.
12145
12146 * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
12147 (YY_REDUCE_PRINT): New.
12148 (yyparse): Use them.
12149 * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
12150 YYDPRINT here.
12151 (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
12152 state reached after the reduction/recovery, since...
12153 (yyparse, yyprocessOneStack): Report the state we are entering in.
12154
12155 2002-11-16 Akim Demaille <akim@epita.fr>
12156
12157 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
12158 Add support for --trace=skeleton.
12159 * src/scan-skel.l: %option debug.
12160 Scan strings of non-@ or \n instead of character by character.
12161 (scan_skel): Handle trace_skeleton.
12162 (QPUTS): New.
12163 (@output_parser_name@, @output_header_name@): ``Restore'' their
12164 support (used to be M4 macros).
12165 * data/yacc.c: Quote larger chunks, a la glr.c.
12166 * data/lalr1.cc: Likewise.
12167 The header guards are no longer available, so use some other
12168 string than `YYLSP_NEEDED'.
12169
12170 2002-11-16 Akim Demaille <akim@epita.fr>
12171
12172 Make the ``Printers and Destructors'' test more verbose, taking
12173 `yacc.c''s behavior as (possibly wrong) reference.
12174
12175 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
12176 instead of fprint on stdout.
12177 Set and report the last_line of the symbols.
12178 Consistently display values and locations.
12179
12180 2002-11-16 Paul Eggert <eggert@twinsun.com>
12181
12182 * data/yacc.c: Avoid over-quoting of __line__ and __file__.
12183
12184 2002-11-15 Paul Eggert <eggert@twinsun.com>
12185
12186 * tests/actions.at (Actions after errors): New test case.
12187
12188 * data/glr.c, data/lalr1.cc, data/yacc.cc, doc/bison.texinfo,
12189 src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
12190 tests/action.at, tests/calc.at, tests/conflicts.at,
12191 tests/cxx-type.at, tests/regression.at:
12192 "parse error" -> "syntax error" for POSIX compatibility.
12193 "parsing stack overflow..." -> "parser stack overflow" so
12194 that code matches Bison documentation.
12195
12196 2002-11-15 Akim Demaille <akim@epita.fr>
12197
12198 * src/parse-gram.y (declaration): Have %parse-param and %lex-param
12199 take two BRACED_CODE, not two string_content.
12200 Free the scanner's obstack when we are done.
12201 (code_content): New.
12202 * tests/calc.at: Adjust.
12203 * doc/bison.texinfo: Adjust.
12204 Also, make sure to include the `,' for these declarations.
12205
12206 2002-11-15 Tim Van Holder <tim.van.holder@pandora.be>
12207
12208 * m4/prereq.m4: Removed the commented jm_PREREQ_HASH
12209 definition; avoids potential autoreconf problems.
12210
12211 2002-11-15 Akim Demaille <akim@epita.fr>
12212
12213 Always check the value returned by yyparse.
12214
12215 * tests/calc.at (_AT_DATA_CALC_Y): Have `main' exit with the value
12216 returned by yyparse.
12217 (_AT_CHECK_CALC_ERROR): Take the expected exit value as argument.
12218 Adjust calls.
12219 * tests/glr-regr1.at (glr-regr1.y): Have `main' exit with the value
12220 returned by yyparse.
12221
12222 2002-11-14 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12223
12224 * data/glr.c (yyFail): Always set yyerrflag. Corrects regression
12225 on input.at test.
12226
12227 2002-11-14 Paul Eggert <eggert@twinsun.com>
12228
12229 * src/output.c (output_skeleton): Call xfopen instead of
12230 duplicating xfopen's body.
12231
12232 Fix bugs reported by Nelson H. F. Beebe in
12233 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00078.html>.
12234
12235 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
12236 "$CC -E foo.h" is allowed, as this doesn't work with the Portland
12237 Group compiler. Instead, use "$CC -E bar.c". Include the .h
12238 file twice in the grammar, as an extra check.
12239
12240 * tests/input.at (Torturing the Scanner): Surround the
12241 backslash-newline tests with "#if 0", to make it less likely that
12242 we'll run into compiler bugs. Bring back solitary \ inside
12243 comment, but add a closing comment to work around HP C bug. Don't
12244 test backslash-newline in C character constant.
12245
12246 2002-11-14 Akim Demaille <akim@epita.fr>
12247
12248 * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
12249 status of the compiler.
12250 Calling `exit 1' is no longer needed.
12251 Reported by Nelson H. F. Beebe.
12252
12253 2002-11-14 Akim Demaille <akim@epita.fr>
12254
12255 * tests/atlocal.in (CPPFLAGS): We have config.h.
12256 * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR):
12257 New.
12258 * tests/actions.at, tests/calc.at, tests/conflicts.at,
12259 * tests/cxx-type.at, tests/glr-regr1.at, tests/headers.at,
12260 * tests/regression.at, tests/torture.at: Use them for all the
12261 grammars that are to be compiled.
12262 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Rename as...
12263 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): this.
12264 * doc/bison.texinfo (GLR Parsers): Document `inline'.
12265
12266 2002-11-14 Akim Demaille <akim@epita.fr>
12267
12268 * doc/bison.texinfo: Various formatting changes (alignments in
12269 samples, additional @group/@end group, GCS in samples.
12270 Use @deffn instead of simple @table to define the directives,
12271 macros, variables etc.
12272
12273 2002-11-13 Paul Eggert <eggert@twinsun.com>
12274
12275 Fix some bugs reported by Albert Chin-A-Young in
12276 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00066.html>.
12277
12278 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
12279 -o c"; the HP C compiler chatters during compilation.
12280 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
12281 * tests/headers.at (export YYLTYPE): Likewise.
12282
12283 * tests/input.at (Torturing the Scanner): Remove lines containing
12284 solitary backslashes, as they tickle a bug in the HP C compiler.
12285
12286 * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
12287 comments, since they're not portable. Use GNU coding style.
12288
12289 2002-11-13 Akim Demaille <akim@epita.fr>
12290
12291 * data/yacc.c: Leave bigger chunks of quoted text.
12292 (YYDSYMPRINTF): New.
12293 Use it to report symbol activities.
12294 * data/glr.c (YYDSYMPRINTF): New.
12295 Use it.
12296
12297 2002-11-12 Paul Eggert <eggert@twinsun.com>
12298
12299 Version 1.75b.
12300
12301 * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
12302 (yyglrReduce): Return yyok, not 0.
12303 This should avoid the enumerated-type warnings reported
12304 by Nelson H. F. Beebe in
12305 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00057.html>.
12306
12307 * lib/bbitset.h (BITSET_INLINE): Remove.
12308 * lib/bitset.h [! BITSET_INLINE]: Remove.
12309 (bitset_set, bitset_reset, bitset_test): Rename local vars
12310 to avoid shadowing warnings by GCC.
12311
12312 * data/glr.c (inline): Remove #define. It's the user's
12313 responsibility to #define it away, just like 'const'.
12314 This fixes one of the bugs reported by Nelson H. F. Beebe in
12315 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00058.html>.
12316
12317 * Makefile.maint (po-check): Scan .l and .y files instead of the
12318 .c and the .h files that they generate. This fixes the bug
12319 reported by Tim Van Holder in:
12320 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00062.html>
12321 Look for N_ as well as for _. Try to avoid matching #define for
12322 N_ and _.
12323 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
12324 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
12325 * src/scan-gram.l: Revamp regular expressions so that " and '
12326 do not confuse xgettext.
12327
12328 * src/struniq.h (struniq_new): Do not declare the return type
12329 to be 'const'; this violates the C standard.
12330 * src/struniq.c (struniq_new): Likewise.
12331
12332 2002-11-12 Albert Chin-A-Young <china@thewrittenword.com>
12333
12334 * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the
12335 duplicate definition of optind on Tru64 UNIX 4.0D with the Compaq
12336 linker.
12337
12338 2002-11-12 Akim Demaille <akim@epita.fr>

12346
12347 2002-11-12 Akim Demaille <akim@epita.fr>
12348
12349 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Display the
12350 locations.
12351
12352 2002-11-12 Akim Demaille <akim@epita.fr>
12353
12354 * data/c.m4 (b4_yysymprint_generate): Pass *yyvaluep to YYPRINT,
12355 not yyvalue.
12356
12357 2002-11-12 Akim Demaille <akim@epita.fr>
12358
12359 * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.

12363
12364 * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton
12365 defines it.
12366 * data/glr.c (yystos): New.
12367 (b4_yysymprint_generate, b4_yydestruct_generate): Invoke.
12368 (YYDSYMPRINT): New.
12369 (yyval): Don't define it, it is handled via M4.
12370 (yyrecoverParseError): Free verbosely the discarded symbols.
12371 * data/yacc.c (yysymprint): Remove, rather...
12372 (b4_yysymprint_generate): invoke.

12374 Accept pointers as arguments, as opposed to the version from
12375 yacc.c.
12376 (b4_yydestruct_generate): Likewise.
12377 * tests/cations.at (Printers and Destructors): Use Bison directives
12378 instead of CPP macros.
12379 Don't rely on internal details.
12380
12381 2002-11-12 Akim Demaille <akim@epita.fr>
12382
12383 * data/c.m4 (b4_yydestruct_generate, b4_symbol_actions): New.
12384 * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
12385 Don't work on yychar (i.e., do set it to YYEMPTY, don't match
12386 it against YYEMPTY and so forth), work on yytoken (i.e., set
12387 it to YYEMPTY etc.).
12388 (yydestruct): Replace with a b4_yydestruct_generate invocation.
12389 (b4_symbol_actions): Remove.
12390 * data/glr.c (YYTRANSLATE): As for yacc.c, if negative, it stands
12391 for 0, end-of-input.
12392
12393 2002-11-12 Akim Demaille <akim@epita.fr>
12394
12395 * doc/bison.texinfo (Destructor Decl): New.
12396
12397 2002-11-12 Akim Demaille <akim@epita.fr>
12398
12399 * src/tables.c (tables_generate): Use free for pointers that
12400 cannot be NULL, not XFREE.
12401 (pack_vector): Use assert, not fatal, for bound violations.
12402 * src/state.c (state_new): Likewise.
12403 * src/reader.c (reader): Likewise.
12404 * src/lalr.c (set_goto_map): Likewise.
12405 * src/location.h (LOCATION_PRINT): If first_line is 0, just issue
12406 the file name.
12407
12408 2002-11-12 Akim Demaille <akim@epita.fr>
12409
12410 * src/scan-gram.l, src/reader.h (scanner_last_string_free):
12411 Restore.
12412 * src/scan-gram.l (last_string): Is global to the file, not to
12413 yylex.
12414 * src/parse-gram.y (input): Don't append the epilogue here,
12415 (epilogue.opt): do it here, and free the scanner's obstack.
12416 * src/reader.c (epilogue_set): Rename as...
12417 (epilogue_augment): this.
12418 * data/c.m4 (b4_epilogue): Defaults to empty.
12419
12420 2002-11-12 Akim Demaille <akim@epita.fr>
12421
12422 * src/getargs.c (long_options): Remove duplicates.
12423 * src/vmsgetargs.c, src/build.com, src/bison.cld, src/vmshlp.mar:

12426 * doc/bison.texinfo (VMS Invocation): Remove.
12427
12428 2002-11-12 Akim Demaille <akim@epita.fr>
12429
12430 * src/struniq.h, src/struniq.c (struniq_t): Is const.
12431 (STRUNIQ_EQ, struniq_assert, struniq_assert_p): New.
12432
12433 Use struniq for symbols.
12434
12435 * src/symtab.h (symbol_t): The tag member is a struniq.
12436 (symbol_type_set): Adjust.
12437 * src/symtab.c (symbol_new): Takes a struniq.
12438 (symbol_free): Don't free the tag member.
12439 (hash_compare_symbol_t, hash_symbol_t): Rename as...
12440 (hash_compare_symbol, hash_symbol): these.
12441 Use the fact that tags as struniqs.
12442 (symbol_get): Use struniq_new.
12443 * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get):
12444 Returns a strniq.
12445 * src/reader.h (merger_list, grammar_currentmerge_set): The name
12446 and type members are struniqs.
12447 * src/reader.c (get_merge_function)
12448 (grammar_current_rule_merge_set): Adjust.
12449 (TYPE, current_type): Are struniq.
12450
12451 Use struniq for file names.
12452
12453 * src/files.h, src/files.c (infile): Split into...
12454 (grammar_file, current_file): these.
12455 * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust.
12456 * src/reduce.c (reduce_print): Likewise.
12457 * src/getargs.c (getargs): Likewise.
12458 * src/complain.h, src/complain.c: Likewise.
12459 * src/main.c (main): Call struniqs_new early enough to use it for
12460 file names.
12461 Don't free the input file name.
12462
12463 2002-11-12 Akim Demaille <akim@epita.fr>
12464
12465 * src/symtab.c (symbol_free): Remove dead deactivated code:

12467 Don't use XFREE to free items that cannot be NULL.
12468 * src/struniq.h, src/struniq.c: New.
12469 * src/main.c (main): Initialize/free struniqs.

12475
12476 2002-11-11 Paul Eggert <eggert@twinsun.com>
12477
12478 Revamp to fix many (but not all) of the C- and M4-related quoting
12479 problems. Among other things, this fixes the Bison bug reported
12480 by Jan Hubicka when processing the Bash grammar; see:
12481 <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
12482
12483 Use new @ escapes consistently. Represent brackets with @{ and @}
12484 rather than @<:@ and @:>@, since this works a bit better with dumb
12485 editors like vi. Represent @ with @@, since @ is now consistently
12486 an escape. Use @oline@ and @ofile@ rather than __oline__ and
12487 __ofile__, to avoid unexpected expansions. Similarly, use @output
12488 rather than #output.
12489
12490 * data/c.m4 (b4_copyright): Omit file name from comment, since
12491 the file name could contain "*/".
12492 (b4_synclines_flag): Don't quote the 2nd argument; it should already
12493 be quoted. All uses changed.
12494
12495 * data/glr.c: Use new @ escapes consistently.
12496 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,
12497 b4_output_header_suffix, b4_output_header_name, b4_header_guard):
12498 Remove, since they couldn't handle arbitrary characters in file
12499 names.
12500 * data/lalr1.cc: Likewise.
12501 * data/yacc.c: Likewise.
12502
12503 * src/files.c (output_infix): Remove; all uses removed.
12504 * src/files.h: Likewise.
12505
12506 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
12507 mishandled funny characters in file names, and anyway it isn't
12508 needed any more.
12509 * data/yacc.c: Likewise.
12510 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
12511
12512 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
12513 * data/yacc.c: Likewise.
12514
12515 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
12516 strings now.
12517 (muscle_init): Quote filename as a C string.
12518 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
12519 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
12520 * src/output.c (escaped_file_name_output): New function.
12521 (prepare_symbols): Quote tokens for M4.
12522 (prepare): Don't insert output_infix, output_prefix,
12523 output_parser_name, output_header_name; this is now down by scan-skel.
12524 Insert skeleton as a C string.
12525
12526 * src/output.c (user_actions_output, symbol_destructors_output,
12527 symbol_printers_output): Quote filenames for C and M4.
12528 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12529
12530 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
12531 escapes other than \\ and \'; this simplifies the code.
12532 (<SC_STRING>): Likewise, for \\ and \".
12533 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
12534 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
12535 Use new escapes @{ and @} for [ and ].
12536
12537 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
12538 them with auto vars.
12539 Switch to new escape scheme, where @ is the escape character uniformly.
12540 Abort if a stray escape character is found. Avoid unbounded input
12541 buffer when parsing non-escaped text.
12542
12543 * tests/input.at (Torturing the Scanner): Add tests that @oline@,
12544 __oline__, #output, $@, and @{ do not have unintended meanings.
12545
12546 2002-11-09 Paul Eggert <eggert@twinsun.com>
12547
12548 Fix the test failure due to GCC warnings described in
12549 <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
12550 * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
12551 evaluate to 0 if it's impossible for NINF to be in the respective
12552 table.
12553 (yygetLRActions, yyrecoverParseError): Use them.
12554
12555 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
12556 counted in the token inserted at end of file. Now takes
12557 location_t *, not location_t, so that the location can be
12558 adjusted. All uses changed.
12559
12560 * tests/regression.at (Invalid inputs): Adjust wording in
12561 diagnostic to match the new behavior.
12562
12563 * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
12564 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
12565 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
12566 abort ();'. This reduces the runtime of the "Many lookaheads"
12567 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
12568 GCC 3.2.
12569
12570 2002-11-07 Paul Eggert <eggert@twinsun.com>
12571
12572 * src/parse-gram.y (CHARACTER): Remove unused token.
12573 All uses removed.
12574
12575 * src/scan-gram.l: Remove stack option. We no longer use the
12576 stack, since the stack was never deeper than 1; instead, use the
12577 new auto var c_context to record the stacked value.
12578
12579 Remove nounput option. At an unexpected end of file, we now unput
12580 the minimal input necessary to end cleanly; this simplifies the
12581 code.
12582
12583 Avoid unbounded token sizes where this is easy.
12584
12585 (unexpected_end_of_file): New function.
12586 Use it to systematize the error message on unexpected EOF.
12587 (last-string): Now auto, not static.
12588 (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
12589 (scanner_last_string_free): Remove; not used.
12590 (percent_percent_count): Move decl to just before use.
12591 (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
12592 not the (never otherwised-used) CHARACTER.
12593
12594 2002-11-07 Akim Demaille <akim@epita.fr>
12595
12596 Let yyerror always receive the msg as last argument, so that
12597 yyerror can be variadic.
12598
12599 * data/yacc.c (b4_yyerror_args): New.
12600 Use it when calling yyerror.
12601 * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
12602 Use it when calling yyerror.
12603 * doc/bison.texinfo (Error Reporting): Adjust.
12604 * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
12605 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
12606
12607 2002-11-06 Akim Demaille <akim@epita.fr>
12608
12609 #line should have quoted strings.
12610 Ideally, this should be done by m4_quotearg.
12611
12612 * src/scan-skel.l: Include quotearg.h.
12613 Quote __ofile__.
12614 * src/output.c (symbol_printers_output)
12615 (symbol_destructors_output): Quote the file name.
12616
12617 2002-11-06 Akim Demaille <akim@epita.fr>
12618
12619 * tests/regression.at (Invalid inputs): Adjust to the recent
12620 messages.
12621
12622 2002-11-06 Akim Demaille <akim@epita.fr>
12623
12624 Restore --no-lines.
12625 Reported by Jim Kent.
12626
12627 * data/c.m4 (b4_syncline): New.
12628 * data/glr.c, data/yacc.c, data/lalr1.cc: Use it.
12629 * src/reader.c (prologue_augment, epilogue_set): Use b4_syncline.
12630 * src/output.c (user_actions_output): Likewise.
12631 (prepare): Define 'b4_synclines_flag'.
12632 * src/muscle_tab.c (muscle_init): Don't define b4_linef.
12633
12634 2002-11-06 Akim Demaille <akim@epita.fr>
12635
12636 * src/main.c (main): Free `infile'.
12637 * src/scan-gram.l (handle_syncline): New.
12638 Recognize `#line'.
12639 * src/output.c (user_actions_output, symbol_destructors_output)
12640 (symbol_printers_output): Use the location's file name, not
12641 infile.
12642 * src/reader.c (prologue_augment, epilogue_set): Likewise.
12643
12644 2002-11-05 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12645
12646 * src/tables.c (matching_state): Don't allow states to match if
12647 either has GLR conflict entries.
12648
12649 2002-11-05 Paul Eggert <eggert@twinsun.com>
12650
12651 * src/scan-gram.l: Use more accurate diagnostics, e.g.
12652 "integer out of range" rather than "invalid value".
12653 * tests/input.at (Invalid $n, Invalid @n): Change expected wording
12654 accordingly.
12655
12656 Scan <% and %> digraphs in C code as POSIX 1003.1-2001 requires.
12657 Also, remove one static variable in the scanner.
12658
12659 * src/scan-gram.l (braces_level): Now auto, not static.
12660 Initialize to zero if the compiler is being picky.
12661 (INITIAL): Clear braces_level instead of incrementing it.
12662 (SC_BRACED_CODE): Treat <% and %> as { and } when inside C code,
12663 as POSIX 1003.1-2001 requires.
12664 * src/system.h (IF_LINT): New macro, taken from coreutils.
12665 * configure.ac: Define "lint" if --enable-gcc-warnings.
12666
12667 2002-11-05 Akim Demaille <akim@epita.fr>
12668
12669 * src/scan-gram.l: When it starts with `%', complain about the
12670 whole directive, not just that `invalid character: %'.
12671
12672 2002-11-04 Akim Demaille <akim@epita.fr>
12673
12674 * Makefile.maint: Update from Autoconf.

12676
12677 2002-11-04 Akim Demaille <akim@epita.fr>
12678
12679 * tests/glr-regr1.at (Badly Collapsed GLR States): Prototype yylex
12680 and yyerror.
12681 Have yyerror `use' its arguments.
12682 * tests/calc.at (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF
12683 returns true when location & yacc & pure & parse-param.
12684 (_AT_DATA_CALC_Y): Let yyerror ``use'' its arguments.
12685
12686 2002-11-04 Akim Demaille <akim@epita.fr>
12687
12688 * src/location.h (LOCATION_PRINT): Use quotearg slot 3 to avoid
12689 clashes.
12690 * src/scan-gram.l: Use [\'] instead of ['] to pacify
12691 font-lock-mode.
12692 Use complain_at.
12693 Use quote, not quote_n since LOCATION_PRINT no longer uses the
12694 slot 0.
12695
12696 2002-11-03 Paul Eggert <eggert@twinsun.com>
12697
12698 * src/reader.c (get_merge_function, grammar_current_rule_check):
12699 Use consistent diagnostics for reporting type name clashes.
12700 Quote the types with <>, for consistency with Yacc.
12701 * tests/input.at (Type Clashes): Adjust to diagnostic changes.
12702
12703 2002-11-03 Akim Demaille <akim@epita.fr>
12704
12705 * data/c.m4 (b4_identification, b4_user_args, b4_parse_param):
12706 New.
12707 * data/yacc.m4 (b4_pure_args, b4_Pure_args): New.
12708 (b4_parse_param): Remove.
12709 Use b4_identification.
12710 Propagate b4_pure_args where needed to pass them to yyerror.
12711 * data/glr.m4 (b4_parse_param): Remove.
12712 (b4_user_formals, b4_pure_args, b4_pure_formals, b4_lpure_args)
12713 (b4_lpure_formals): New.
12714 Use b4_identification.
12715 (YY_USER_FORMALS, YY_USER_ARGS): Remove, replaced by
12716 b4_user_formals and b4_user_args.
12717 (yyexpandGLRStack, yyFail, yyaddDeferredAction, yyglrShiftDefer)
12718 (yyreportAmbiguity): When using a pure parser, also need
12719 the location, and the parse-params.
12720 Adjust callers.
12721 (yyuserAction, yyglrShift, yyreportParseError, yyrecoverParseError):
12722 When using a pure parser, also need the parse-params.
12723 Adjust callers.
12724 * tests/calc.at: Test pure (%pure-parser) and absolutely pure
12725 (%pure-parser + %parse-param) LALR and GLR parsers.
12726 (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): New, define AT_PARAM_IF,
12727 AT_LOCATION_IF, AT_PURE_IF, AT_GLR_IF, AAT_PURE_AND_LOC_IF,
12728 AT_GLR_OR_PARAM_IF, AT_YYERROR_ARG_LOC_IF, AT_YYERROR_SEES_LOC_IF.
12729 (_AT_DATA_CALC_Y): Equip for purity of yyerror.
12730 (_AT_CHECK_CALC_ERROR): Use AT_YYERROR_SEES_LOC_IF.
12731 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Equip for yyerror purity.
12732 * doc/bison.texinfo: Untabify the whole file.
12733 (Parser Function): Document %parse-param, deprecate YYPARSE_PARAM.
12734 (Pure Calling): Document %lex-param, deprecate YYLEX_PARAM.
12735 (Error Reporting): Adjust to these new directives.
12736 Document %error-verbose, deprecate YYERROR_VERBOSE.
12737
12738 2002-11-03 Akim Demaille <akim@epita.fr>
12739
12740 * tests/calc.at: Change all the AT_CHECK_CALC_LALR and
12741 AT_CHECK_CALC_GLR invocations to use % directives, instead of
12742 command line options.
12743 * tests/cxx-type.at: Formatting changes.
12744
12745 2002-11-03 Paul Eggert <eggert@twinsun.com>
12746
12747 * src/scan-gram.l: Revamp to fix POSIX incompatibilities,
12748 to count columns correctly, and to check for invalid inputs.
12749
12750 Use mbsnwidth to count columns correctly. Account for tabs, too.
12751 Include mbswidth.h.
12752 (YY_USER_ACTION): Invoke extend_location rather than LOCATION_COLUMNS.
12753 (extend_location): New function.
12754 (YY_LINES): Remove.
12755
12756 Handle CRLF in C code rather than in Lex code.
12757 (YY_INPUT): New macro.
12758 (no_cr_read): New function.
12759
12760 Scan UCNs, even though we don't fully handle them yet.
12761 (convert_ucn_to_byte): New function.
12762
12763 Handle backslash-newline correctly in C code.
12764 (SC_LINE_COMMENT, SC_YACC_COMMENT): New states.
12765 (eols, blanks): Remove. YY_USER_ACTION now counts newlines etc.;
12766 all uses changed.
12767 (tag, splice): New EREs. Do not allow NUL or newline in tags.
12768 Use {splice} wherever C allows backslash-newline.
12769 YY_STEP after space, newline, vertical-tab.
12770 ("/*"): BEGIN SC_YACC_COMMENT, not yy_push_state (SC_COMMENT).
12771
12772 (letter, id): Don't assume ASCII; e.g., spell out a-z.
12773
12774 ({int}, handle_action_dollar, handle_action_at): Check for integer
12775 overflow.
12776
12777 (YY_STEP): Omit trailing semicolon, so that it's more like C.
12778
12779 (<SC_ESCAPED_STRING,SC_ESCAPED_CHARACTER>): Allow \0 and \00
12780 as well as \000. Check for UCHAR_MAX, not 255.
12781 Allow \x with an arbitrary positive number of digits, as in C.
12782 Check for overflow here.
12783 Allow \? and UCNs, for compatibility with C.
12784
12785 (handle_symbol_code_dollar): Use quote_n slot 1 to avoid collision
12786 with quote slot used by complain_at.
12787
12788 * tests/input.at: Add tests for backslash-newline, m4 quotes
12789 in symbols, long literals, and funny escapes in strings.
12790
12791 * configure.ac (jm_PREREQ_MBSWIDTH): Add.
12792 * lib/Makefile.am (libbison_a_SOURCES): Add mbswidth.h, mbswidth.c.
12793 * lib/mbswidth.h, lib/mbswidth.c: New files, from GNU gettext.
12794 * m4/Makefile.am (EXTRA_DIST): Add mbswidth.m4.
12795 * m4/mbswidth.m4: New file, from GNU coreutils.
12796
12797 * doc/bison.texinfo (Grammar Outline): Document // comments.
12798 (Symbols): Document that trigraphs have no special meaning in Bison,
12799 nor is backslash-newline allowed.
12800 (Actions): Document that trigraphs have no special meaning.
12801
12802 * src/location.h (LOCATION_COLUMNS, LOCATION_LINES): Remove;
12803 no longer used.
12804
12805 2002-11-02 Paul Eggert <eggert@twinsun.com>
12806
12807 * src/reader.c: Don't include quote.h; not needed.
12808 (get_merge_function): Reword warning to be consistent with
12809 type clash diagnostic in grammar_current_rule_check.
12810
12811 * lib/quotearg.c (quotearg_buffer_restyled): Fix off-by-two
12812 bug in trigraph handling.
12813
12814 * src/output.c (prepare_symbols): When printing token names,
12815 escape "[" as "@<:@" and likewise for "]".
12816
12817 * src/system.h (errno): Remove declaration, as we are now
12818 assuming C89 or better, and C89 guarantees errno.
12819
12820 2002-10-30 Paul Eggert <eggert@twinsun.com>
12821
12822 * lib/bitset_stats.c (bitset_stats_read, bitset_stats_write):
12823 Check for close failures.
12824 * src/files.h (xfclose): Return void, not int, since it always
12825 returned zero.
12826 * src/files.c (xfclose): Likewise. Report I/O error if ferror
12827 indicates one.
12828 * src/output.c (output_skeleton): Use xfclose rather than fclose
12829 and ferror. xfclose now checks ferror.
12830
12831 * data/glr.c (YYLEFTMOST_STATE): Remove.
12832 (yyreportTree): Use a stack-based leftmost state. This avoids
12833 our continuing battles with bogus warnings about initializers.
12834
12835 2002-10-30 Akim Demaille <akim@epita.fr>
12836
12837 * src/system.h: Don't use #ifdef/#ifndef on HAVE_ values, only
12838 #if.
12839
12840 2002-10-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
12841
12842 * tests/glr-regr1.at: New test for reported regressions.
12843 * tests/testsuite.at: Add glr-regr1.at test.
12844 * tests/Makefile.am: Add glr-regr1.at test.
12845
12846 2002-10-24 Paul Eggert <eggert@twinsun.com>
12847
12848 Version 1.75a.
12849
12850 * tests/calc.at (_AT_DATA_CALC_Y): Remove unused strcat declaration.
12851 * tests/cxx-type.at (_AT_TEST_GLR_CALC): Include stdlib.h, since
12852 we use malloc. Don't assume 'A' through 'Z' are contiguous.
12853 Don't assume strdup exists; POSIX says its an XSI extension.
12854 Check for buffer overflow on input.
12855
12856 2002-10-24 Akim Demaille <akim@epita.fr>
12857
12858 * src/output.c (output_skeleton): Don't disable M4sugar comments
12859 too soon: it results in comments being expanded.
12860 * data/yacc.c, data/glr.c, data/lalr1.cc: Do it right before the
12861 first output.
12862
12863 2002-10-24 Akim Demaille <akim@epita.fr>
12864
12865 * data/yacc.c (m4_int_type): New.
12866 * data/c.m4 (m4_int_type): Don't use yysigned_char, but `signed
12867 char' as only yacc.c wants K&R portability.
12868 * data/glr.c (yysigned_char): Remove.
12869 * data/lalr1.cc: Rename the trailing b4_name as b4_parser_class_name.
12870 Reported by Quoc Peyrot.
12871
12872 2002-10-23 Paul Eggert <eggert@twinsun.com>
12873
12874 * src/main.c (main): With --trace=time, report times even if a
12875 non-fatal error occurs. Formerly, the times were reported in some
12876 such cases but not in others.
12877 * src/reader.c (reader): Just return if a complaint has been issued,
12878 instead of exiting, so that 'main' can report times.
12879
12880 2002-10-22 Akim Demaille <akim@epita.fr>
12881
12882 * src/system.h: Include sys/types.
12883 Reported by Bert Deknuydt.
12884
12885 2002-10-23 Paul Eggert <eggert@twinsun.com>
12886
12887 * configure.ac (AC_PROG_LEX): Use instead of AM_PROG_LEX.
12888 Suggested by Art Haas.
12889
12890 2002-10-22 Paul Eggert <eggert@twinsun.com>
12891
12892 * src/complain.c (exit) [! (STDC_HEADERS || _LIBC)]: Remove exit
12893 decl; not needed any more.
12894 * src/main.c (main): Use return to exit, undoing yesterday's change.
12895 The last OS that we could find where this wouldn't work is
12896 SunOS 3.5, and that's too old to worry about now.
12897
12898 * data/glr.c (struct yyltype): Define members even when not
12899 doing locations. This is more consistent with yacc.c, and it
12900 works around the following bug reports:
12901 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00106.html
12902 http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00111.html
12903
12904 * doc/bison.texinfo: Minor spelling and typographical fixes. Use
12905 @acronym consistently. Standardize on "Yacc" instead of "YACC",
12906 "Algol" instead of "ALGOL". Give a bit more history about BNF.
12907
12908 2002-10-22 Akim Demaille <akim@epita.fr>
12909
12910 * data/README: New.
12911
12912 2002-10-21 Paul Eggert <eggert@twinsun.com>
12913
12914 Be consistent about 'bool'; the old code used an enum in one
12915 module and an int in another, and this violates the C standard.
12916 * m4/stdbool.m4: New file, from coreutils 4.5.3.
12917 * configure.ac (AC_HEADER_STDBOOL): Add.
12918 * m4/Makefile.am (EXTRA_DIST): Add stdbool.m4.
12919 * src/muscle_tab.c (hash_compare_muscles): (a ? FALSE : TRUE) -> (! a)
12920 * src/symtab.c (hash_compare_symbol_t): Likewise.
12921 * src/system.h (bool, false, true): Use a definition consistent
12922 with ../lib/hash.c. All uses changed.
12923
12924 * src/complain.c (warning_issued): Renamed from warn_message_count,
12925 so that we needn't worry about integer overflow (!).
12926 Now of type bool. All uses changed.
12927 (complaint_issued): Renamed from complain_message_count; likewise.
12928
12929 * src/main.c (main): Use exit to exit with failure.
12930
12931 * src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
12932 rather than 1 and 0.
12933 * src/main.c (main): Likewise.
12934 * src/getargs.c (getargs): Likewise.
12935 * src/reader.c (reader): Likewise.
12936
12937 * src/getarg.c (getargs): Remove duplicate code for
12938 "Try `bison --help'".
12939
12940 * src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
12941 What was that "2" for?
12942
12943 * src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
12944 * src/getargs.c (usage): Likewise.
12945
12946 * src/getargs.c (getargs): When there are too few operands, report
12947 the last one. When there are too many, report the first extra
12948 one. This is how diffutils does it.
12949
12950 2002-10-20 Paul Eggert <eggert@twinsun.com>
12951
12952 Remove K&R vestiges.
12953 * configure.ac (AC_C_CONST, AM_C_PROTOTYPES): Remove.
12954 * src/complain.c (VA_START): Remove. Assume prototypes.
12955 (vfprintf) [! (HAVE_VPRINTF || defined vfprintf)]: New macro.
12956 (private_strerror, warn_at, warn, complain_at, complain, fatal_at,
12957 fatal): Assume prototypes.
12958 * src/complain.h: Assume prototypes.
12959 * src/system.h (PARAMS): Remove.
12960 Include <limits.h> unconditionally, since it's guaranteeed even
12961 for a freestanding C89 compiler.
12962 (SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
12963 * src/vmsgetargs.c (getargs, cli_present, cli_get_value): Prototype.
12964
12965 2002-10-20 Akim Demaille <akim@epita.fr>
12966
12967 * src/muscle_tab.c (muscle_grow): Remove trailing debugging code.
12968 * data/glr.c (YY_USER_FORMALS, YY_USER_ARGS): New.
12969 (yyuserAction, yydoAction, yyglrReduce, yyresolveValue)
12970 (yyresolveStates, yyresolveAction, yyresolveStack)
12971 (yyprocessOneStack): Use them.
12972 (yy_reduce_print): New.
12973 * tests/calc.at (_AT_DATA_CALC_Y): Exercise %parse-param.
12974
12975 2002-10-20 Akim Demaille <akim@epita.fr>
12976
12977 * data/c.m4 (b4_c_ansi_args): Recognize functions with no
12978 arguments and output `void'.
12979 (b4_c_function): Rename as...
12980 (b4_c_function_def): this.
12981 (b4_c_function_decl, b4_c_ansi_function_def)
12982 (b4_c_ansi_function_decl): New.
12983 Change the interpretation of the arguments: before `int, foo', now
12984 `int foo, foo'.
12985 * data/yacc.c (yyparse): Prototype and define thanks to these.
12986 Adjust b4_c_function_def uses.
12987 * data/glr.c (yyparse): Likewise, but ANSI only.
12988
12989 2002-10-20 Akim Demaille <akim@epita.fr>
12990
12991 * src/output.c (prepare): Move the definition of `tokens_number',
12992 `nterms_number', `undef_token_number', `user_token_number_max'
12993 to...
12994 (prepare_tokens): Here.
12995 (prepare_tokens): Rename as...
12996 (prepare_symbols): this.
12997 (prepare): Move the definition of `rules_number' to...
12998 (prepare_rules): here.
12999 (prepare): Move the definition of `last', `final_state_number',
13000 `states_number' to...
13001 (prepare_states): here.
13002 * data/yacc.c, data/lalr1.cc, data/glr.c: Normalize `>' into `<'.
13003
13004 2002-10-20 Akim Demaille <akim@epita.fr>
13005
13006 * src/tables.h, src/tables.c, src/output.c: Comment changes.
13007
13008 2002-10-20 Akim Demaille <akim@epita.fr>
13009
13010 * data/yacc.c, data/yacc.c (b4_location_if, b4_pure_if): Move to...
13011 * data/c.m4: here.
13012
13013 2002-10-20 Akim Demaille <akim@epita.fr>
13014
13015 * src/output.c (prepare): Use MUSCLE_INSERT_STRING.
13016 * src/muscle_tab.c (muscle_pair_list_grow): Rename `val as
13017 `pair'.
13018 (muscle_init): Move the `b4_ltype', `b4_maxdepth', `b4_initdepth',
13019 `name' to...
13020 * data/glr.c, data/lalr1.cc, data/yacc.c (b4_location_type)
13021 (b4_stack_depth_init, b4_stack_depth_max, b4_parser_class_name):
13022 These.
13023
13024 2002-10-19 Paul Eggert <eggert@twinsun.com>
13025
13026 Do not create a temporary file, as that involves security and
13027 cleanup headaches. Instead, use a pair of pipes.
13028 Derived from a suggestion by Florian Krohm.
13029 * lib/subpipe.c, lib/subpipe.h, m4/subpipe.m4: New files.
13030 * lib/mkstemp.c, lib/readpipe.c, lib/tempname.c, m4/mkstemp.m4: Remove.
13031 * configure.ac (UTILS_FUNC_MKSTEMP, jm_PREREQ_TEMPNAME): Remove.
13032 (BISON_PREREQ_SUBPIPE): Add.
13033 * lib/Makefile.am (libbison_a_SOURCES): Remove readpipe.c.
13034 Add subpipe.h, subpipe.c.
13035 * m4/Makefile.am (EXTRA_DIST): Remove mkstemp.m4. Add subpipe.m4.
13036 * po/POTFILES.in: Add lib/subpipe.c.
13037 * src/output.c: Include "subpipe.h".
13038 (m4_invoke): Remove decl.
13039 (scan_skel): New decl.
13040 (output_skeleton): Use pipe rather than temporary file for m4 input.
13041 Check that m4sugar.m4 is readable, to avoid deadlock.
13042 Check for pipe I/O error.
13043 * src/scan-skel.l (readpipe): Remove decl.
13044 (scan_skel): New function, to be used in place of m4_invoke.
13045 Read from stream rather than file.
13046
13047 * lib/timevar.c (TICKS_TO_MSEC, CLOCKS_TO_MSEC): Do not cast to
13048 float, as this generates a warning on Solaris 8 + GCC 3.2 with
13049 --enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
13050 this generates a more-accurate value anyway.
13051
13052 * lib/timevar.c (timervar_accumulate): Rename locals to
13053 avoid confusion with similarly-named more-global.
13054 * src/muscle_tab.c (muscle_pair_list_grow): Likewise.
13055
13056 * src/output.c (prepare): Use xstrdup to convert char const *
13057 to char *, to avoid GCC warning.
13058
13059 2002-10-19 Akim Demaille <akim@epita.fr>
13060
13061 * tests/calc.at (_AT_DATA_CALC_Y): Define VAL, LOC, LEX_FORMALS,
13062 LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
13063 Use them to have `calc.y' ready for %pure-parser.
13064 * data/yacc.c (YYLEX): Pass a yylex return type to
13065 b4_c_function_call.
13066
13067 2002-10-19 Akim Demaille <akim@epita.fr>
13068
13069 Prototype support of %lex-param and %parse-param.
13070
13071 * src/parse-gram.y: Add the definition of the %lex-param and
13072 %parse-param tokens, plus their rules.
13073 Drop the `_' version of %glr-parser.
13074 Add the "," token.
13075 * src/scan-gram.l (INITIAL): Scan them.
13076 * src/muscle_tab.c: Comment changes.
13077 (muscle_insert, muscle_find): Rename `pair' as `probe'.
13078 * src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
13079 (muscle_entry_s): The `value' member is no longer const.
13080 Adjust all dependencies.
13081 * src/muscle_tab.c (muscle_init): Adjust: use
13082 MUSCLE_INSERT_STRING.
13083 Initialize the obstack earlier.
13084 * src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
13085 (muscle_pair_list_grow): New.
13086 * data/c.m4 (b4_c_function_call, b4_c_args): New.
13087 * data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
13088 * tests/calc.at: Use %locations, not --locations.
13089 (AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
13090
13091 2002-10-19 Akim Demaille <akim@epita.fr>
13092
13093 * src/getargs.c (usage): Take status as argument and exit
13094 accordingly.
13095 Report the traditional `Try ... --help' message when status != 0.
13096 (usage, version): Don't take a FILE * as arg, it is pointless.
13097 (getargs): When there is an incorrect number of arguments, make it
13098 an error, and report it GNUlically thanks to `usage ()'.
13099
13100 2002-10-18 Paul Eggert <eggert@twinsun.com>
13101
13102 * data/glr.c (yyreportParseError): Don't assume that sprintf
13103 yields the length of the printed string, as this is not true
13104 on SunOS 4.1.4. Reported by Peter Klein.
13105
13106 * tests/calc.at (_AT_DATA_CALC_Y): #undef memcmp and realloc.
13107 * tests/conflicts.at (%nonassoc and eof): Likewise.
13108 Fixes SunOS 4.1.4 test failure reported by Peter Klein.
13109
13110 2002-10-17 Akim Demaille <akim@epita.fr>
13111
13112 * src/getargs.h (trace_e): Add trace_scan, and trace_parse.
13113 * src/getargs.c (trace_types, trace_args): Adjust.
13114 * src/reader.c (grammar_current_rule_prec_set)
13115 (grammar_current_rule_dprec_set, grammar_current_rule_merge_set):
13116 Standardize error messages.
13117 And s/@prec/%prec/!
13118 (reader): Use trace_flag to enable scanner/parser debugging,
13119 instead of an adhoc scheme.
13120 * src/scan-gram.l: Remove trailing debugging code.

13123
13124 * src/muscle_tab.h (MUSCLE_TAB_H_): Was misspelled as
13125 MUSCLE_TAB_H.
13126
13127 * NEWS: Officially drop support for building Bison with K&R C,
13128 since it didn't work anyway and it's not worth worrying about.
13129 * Makefile.maint (wget_files): Remove ansi2knr.c.
13130 (ansi2knr.c-url_prefix): Remove.

13135 2002-10-15 Paul Eggert <eggert@twinsun.com>
13136
13137 Stop using the "enum_" trick for K&R-style function definitions;
13138 it confused me, and I was the author! Instead, assume that people
13139 who want to use K&R C compilers (when using these modules in GCC,
13140 perhaps?) will run ansi2knr.
13141
13142 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): Remove.
13143 All uses of "enum_" changed to "enum ".

13155 abitset_unused_clear, abitset_xor, abitset_xor_cmp, abitset_zero):

13232 tests/cxx-type.at, tests/headers.at, tests/input.at,
13233 tests/regression.at, tests/synclines.at, tests/torture.at:
13234 Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
13235 so that the tests still work even if POSIXLY_CORRECT is set.
13236 * doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
13237
13238 * data/c.m4 (b4_int_type): Use yysigned_char instead of signed char,
13239 for portability to K&R hosts. Fix typo: signed char is guaranteed
13240 only to 127, not to 128.
13241 * data/glr.c (yysigned_char): New type.
13242 * data/yacc.c (yysigned_char): Likewise.
13243 * tests/regression.at (Web2c Actions): signed char -> yysigned_char.
13244
13245 2002-10-13 Paul Eggert <eggert@twinsun.com>
13246
13247 * data/yacc.c (yyparse): Rewrite to avoid "comparison is always
13248 true due to limited range of data type" warning from GCC.
13249
13250 * data/c.m4 (b4_token_defines): Protect against double-inclusion
13251 by wrapping enum yytokentype's definition inside #ifndef
13252 YYTOKENTYPE. This undoes a bug I introduced on 2002-10-12.
13253

13255

13271
13272 Let nondeterministic skeletons be usable with deterministic
13273 tables.
13274
13275 With the patch, GAWK compiled by GCC without -O2 passes its test
13276 suite using a GLR parser driven by LALR tables. It fails with -O2
13277 because `struct stat' gives two different answers on my machine:
13278 88 (definition of an auto var) and later 96 (memset on this var).
13279 Hence the stack is badly corrumpted. The headers inclusion is to
13280 blame: if I move the awk.h inclusion before GLR's system header
13281 inclusion, the two struct stat have the same size.
13282
13283 * src/tables.c (pack_table): Always create conflict_table.
13284 (token_actions): Always create conflict_list.
13285 * data/glr.c (YYFLAG): Remove, unused.
13286
13287 2002-10-13 Akim Demaille <akim@epita.fr>
13288
13289 * configure.ac (AC_GNU_SOURCE): Use it instead of hand written code.
13290 (O0FLAGS): New.
13291 (VALGRIND, GXX): New.
13292 * tests/atlocal.in (CFLAGS): Use O0FLAGS.
13293 * tests/bison.in: Run $PREBISON a pre-command.
13294 * tests/Makefile.am (maintainer-check, maintainer-check-valgrind)
13295 (maintainer-check-g++): New.
13296 * Makefile.am (maintainer-check): New.

13299
13300 * data/glr.c: Formatting changes.
13301 Tweak some trace messages to match yacc.c's.
13302
13303 2002-10-13 Akim Demaille <akim@epita.fr>
13304
13305 GLR parsers sometimes raise parse errors instead of performing the
13306 default reduction.
13307 Reported by Charles-Henry de Boysson.
13308
13309 * tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
13310 check the length of the traces when %glr.
13311 (_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
13312 GLR's traces.
13313 (AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
13314 Test GLR parsers.
13315 * data/glr.c (YYLEFTMOST_STATE): Fix its value.
13316 (yyltype): Remove the yy prefix from the member names.
13317 (yytable): Complete its comment.
13318 (yygetLRActions): Map error action number from YYTABLE from
13319 YYTABLE_NINF to 0.
13320 (yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
13321 (which was a bug: it should have been YYTABEL_NINF, and yet it was
13322 not satisfying as we could compare an YYACTION computed from
13323 YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
13324 only value for error actions.
13325 (yyreportParseError): In verbose parse error messages, don't issue
13326 `error' in the list of expected tokens.
13327 * data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
13328 next action to perform to match glr.c's decoding.
13329 (yytable): Complete its comment.
13330
13331 2002-10-13 Paul Eggert <eggert@twinsun.com>
13332
13333 Fix problem reported by Henrik Grubbstroem in
13334 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00098.html>:
13335 "nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
13336 because the Bison parser reads the second action before reducing
13337 the first one.
13338 * src/scan-gram.l (rule_length): New static var.
13339 Use it to keep track of the rule length in the scanner, since
13340 we can't expect the parser to be in lock-step sync with the scanner.
13341 (handle_action_dollar, handle_action_at): Use this var.
13342 * tests/actions.at (Exotic Dollars): Test for the problem.
13343
13344 2002-10-12 Paul Eggert <eggert@twinsun.com>
13345
13346 * lib/timevar.c [! IN_GCC && HAVE_SYS_TIME_H]: Include <sys/time.h>.
13347 * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): Check for <sys/time.h>.
13348 Include <sys/time.h> when checking for clock_t and struct tms.
13349 Use same include order as source.
13350 This is for the SunOS 4.1.4 porting bug reported by Peter Klein in
13351 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00016.html>.
13352
13353 * lib/timevar.c: Update copyright date and clarify comments.
13354 (get_time) [IN_GCC]: Keep the GCC version for reference.
13355
13356 * lib/timevar.c, lib/timevar.h, lib/timevar.def: Import
13357 GCC version as of today, then merge Bison's changes.
13358 Change "GCC" to "Bison" in copyright notice. timevar.def's
13359 author is Akim, so change that too.
13360
13361 * src/reader.c (grammar_current_rule_check):
13362 Don't worry about the default action if $$ is untyped.
13363 Prevents bogus warnings reported by Jim Gifford in
13364 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00015.html>.
13365
13366 * data/c.m4 (b4_token_enum): Do not define YYTOKENTYPE.
13367 * data/glr.c, data/lalr1.cc, data/yacc.c:
13368 Output token definitions before the first part of user declarations.
13369 Fixes compatibility problem reported by Jim Gifford for kbd in
13370 <http://lists.gnu.org/archive/html/bug-bison/2002-10/msg00014.html>.
13371
13372 2002-10-11 Paul Eggert <eggert@twinsun.com>
13373
13374 * data/yacc.c (yyreport_parse_error): Remove, putting its body into...
13375 (yyparse): here. This undoes some of the 2002-07-25 change.
13376 Compatibility problem reported by Ralf S. Engelschall with
13377 OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.

13379 2002-10-11 Akim Demaille <akim@epita.fr>
13380

13390 2002-10-10 Paul Eggert <eggert@twinsun.com>
13391
13392 Portability fixes for bitsets; this also avoids several GCC
13393 warnings.
13394
13395 * lib/abitset.c: Include <stddef.h>, for offsetof.
13396 * lib/lbitset.c: Likewise.
13397
13398 * lib/abitset.c (abitset_bytes): Return a size that is aligned
13399 properly for vectors of objects. Do not assume that adding a
13400 header size to a multiple of a word size yields a value that is
13401 properly aligned for the whole union.
13402 * lib/bitsetv.c (bitsetv_alloc): Likewise.
13403
13404 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
13405 unique names for structures.
13406 * lib/ebitset.c (ebitset_bytes): Likewise.
13407 * lib/lbitset.c (lbitset_bytes): Likewise.

13434 * lib/ebitset.h: Likewise.
13435 * lib/lbitset.h: Likewise.
13436
13437 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
13438 All instances of parameters of type enum bitset_opts are now of
13439 type enum_bitset_opts, to conform to the C Standard, and similarly
13440 for enum_bitset_type.
13441 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
13442 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
13443
13444 Do not use "struct bitset_struct" to mean different things in
13445 different modules. Not only is this confusing, it violates
13446 the C Standard, which requires that structure types in different
13447 modules must be compatible if one is to be passed to the other.
13448 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
13449 All instances of "struct bitset_struct *" replaced with "bitset".
13450 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
13451 (union bitset_union, struct abitset_struct, struct ebitset_struct,
13452 struct lbitset_struct, struct bitset_stats_struct): New types.
13453 All uses of struct bitset_struct changed to union bitset_union,
13454 etc.
13455 * lib/abitset.c (struct abitset_struct, abitset,
13456 struct bitset_struct): Remove.
13457 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
13458 struct bitset_struct): Remove.
13459 * lib/ebitset.c (struct ebitset_struct, ebitset, struct
13460 bitset_struct): Remove.
13461 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
13462 Likewise.
13463
13464 Do not call a function of type T using a call that assumes the
13465 function is of a different type U. Standard C requires that a
13466 function must be called with a type that is compatible with its
13467 definition.
13468 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
13469 New decls.
13470 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):

13482
13483 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):

13485
13486 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
13487 GCC warning.
13488 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
13489 Use offsetof, for simplicity.

13491 2002-10-06 Paul Eggert <eggert@twinsun.com>
13492
13493 * lib/bitset.h (bitset_reset): Do not assume that bitset_word is
13494 the same width as int. This reapplies a hunk of the 2002-08-12 patch
13495 <http://lists.gnu.org/archive/html/bison-patches/2002-08/msg00007.html>,
13496 which was inadvertently undone by the 2002-09-30 patch.
13497 * lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
13498 the same width as int.

13509 signifies end-of-input. Warn about negative chars. Mention
13510 the portable Standard C character set.
13511
13512 The GNU coding standard says CFLAGS and YFLAGS are reserved
13513 for the installer to set.
13514 * lib/Makefile.am (AM_CFLAGS): Renamed from CFLAGS.
13515 * src/Makefile.am (AM_CFLAGS): Likewise.

13578 abitset_and_or_cmp, abitset_andn_or, abitset_andn_or_cmp,
13579 abitset_or_and, abitset_or_and_cmp):
13580 Use bitset_windex instead of unsigned int.
13581 * lib/bitsetv.c (bitsetv_dump, debug_bitsetv): Likewise.
13582 * lib/ebitset.c (struct ebitset_struct.size, ebitset_elts_grow,
13583 ebitset_elt_add, ebitset_elt_remove, ebitset_weed,

13597 BITSET_SIZE_MAX): New macros.
13598 (BITSET_INDEX_MAX): Remove. It wasn't right, since it assumed that
13599 sizeof (bitset_word) == sizeof (bitset_windex). All uses changed
13600 to BITSET_WINDEX_MAX.
13601
13602 * lib/bitset.c (bitset_next, bitset_prev, bitset_first,
13603 bitset_last): Return BITSET_BINDEX_MAX (not -1) for no value,

13652 Coreutils 4.5.1.
13653

13703
13704 * doc/bison.texinfo (Conditions): Make explicit that the GPL
13705 exception applies only to yacc.c. This is a modification of a
13706 patch originally suggested by Akim Demaille.

13708 2002-09-06 Akim Demaille <akim@epita.fr>
13709
13710 * data/c.m4 (b4_copyright): Move the GPL exception comment from

13712 * data/yacc.c: here.
13713
13714 * data/lalr1.cc (struct yyltype): Don't define it, since we use
13715 LocationType.
13716 (b4_ltype): Default to yy::Location from location.hh.
13717
13718 2002-09-04 Jim Meyering <jim@meyering.net>
13719
13720 * data/yacc.c: Guard the declaration of yytoknum also with

13723 2002-09-04 Akim Demaille <akim@epita.fr>
13724
13725 * configure.in: Rename as...

13753 (yyreportParseError): Use size_t for yysize.
13754 (yy_yypstack): No longer nested inside yypstates, as nested
13755 functions are not portable. Do not assume size_t is the
13756 same width as int.
13757 (yypstates): Do not assume that ptrdiff_t is the same width
13758 as int, and similarly for yyposn and YYINDEX.
13759
13760 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
13761
13762 * lib/Makefile.am (INCLUDES): Do not include from the intl
13763 directory, which has been removed.

13796 * lib/memrchr.c, lib/mkstemp.c, lib/strchr.c, lib/strnlen.c,
13797 lib/strspn.c, lib/tempname.c: Use GPL, not LGPL.
13798
13799 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
13800 PROTOTYPES to check for prototypes, and "defined __STDC__" to
13801 check for void *.
13802
13803 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
13804 size_t; the old version tried to do this but casted improperly.
13805 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
13806 (bitset_test): Now returns int, not unsigned long.
13807
13808 * lib/bitset_stats.c: Include "gettext.h".
13809 (_): New macro.
13810 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
13811 name locals "index", as it generates unnecessary warnings on some
13812 hosts that have an "index" function.
13813
13814 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
13815 bitset_stats_read, bitset_stats_write): Wrap strings in _() if
13816 they need translation.
13817 * src/LR0.c (state_list_append, new_itemsets, get_state,
13818 append_states, generate_states): Likewise.
13819 * src/assoc.c (assoc_to_string): Likewise.

13836 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
13837 lib/timevar.c.
13838 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
13839 manual recommends.
13840 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
13841
13842 * src/complain.c (strerror_r): Remove decl; not needed.
13843 (strerror): Use same pattern as ../lib/error.c.
13844
13845 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
13846
13847 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
13848
13849 * src/main.c (main): Cast result of bindtextdomain and textdomain
13850 to void, to avoid a GCC warning when --disable-nls is in effect.
13851
13852 * src/scan-gram.l: Use strings rather than escapes when possible,
13853 to minimize the number of warnings from xgettext.
13854 (handle_action_dollar, handle_action_at): Don't use isdigit,
13855 as it mishandles negative chars and it may not work as expected
13856 outside the C locale.
13857
13858 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
13859 this is a GCC extension and is not portable to other compilers.
13860

13896 * tests/conflicts.at, tests/reduce.at: Adjust.

13899
13900 Instead of attaching lookaheads and duplicating the rules being
13901 reduced by a state, attach the lookaheads to the reductions.

13937
13938 2002-08-01 Akim Demaille <akim@epita.fr>
13939
13940 * lib/timevar.c (get_time): Include children time.

13944 * src/lalr.h, src/lalr.c (lalr_free): New.

13992 (main): Replace `stage' invocations with timevar calls.
13993 * src/output.c: Insert pertinent timevar calls.
13994

13999 * src/getargs.h (enum trace_e): New.
14000 * src/getargs.c (trace_args, trace_types, trace_argmatch): New.
14001 (long_options, short_options): --trace/-T takes an optional

14003 Change all the uses of trace_flag to reflect the new flags.
14004 * tests/sets.at (Firsts, Nullable, Broken Closure): Use --trace=sets.

14038 by conflicts.
14039
14040 * src/LR0.c (save_reductions): Don't make the final state too
14041 different: save its reduction (accept) instead of having a state
14042 without any action (no shift or goto, no reduce).
14043 Note: the final state is now a ``regular'' state, i.e., the
14044 parsers now contain `reduce 0' as default reduction.
14045 Nevertheless, since they decide to `accept' when yystate =
14046 final_state, they still will not reduce rule 0.
14047 * src/print.c (print_actions, print_reduction): Adjust.
14048 * src/output.c (action_row): Track reduced rules.
14049 (token_actions): Report rules never reduced.

14084 * src/reduce.c (reduce_grammar): When the language is empty,
14085 complain about the start symbol, not the axiom.
14086 Use its location.
14087 * tests/reduce.at (Empty Language): New.
14088
14089 2002-07-26 Akim Demaille <akim@epita.fr>
14090
14091 * src/reader.h, src/reader.c (gram_error): ... can't get
14092 yycontrol without making too strong assumptions on the parser
14093 itself.
14094 * src/output.c (prepare_tokens): Use the real 0th value of
14095 token_translations instead of `0'.
14096 * src/parse-gram.y (yyerror): Don't rely on yycontrol being
14097 visible here.
14098 * data/yacc.c (yyreport_parse_error): Rename yylocation as yylloc
14099 for the time being: %locations ought to provide it to yyerror.

14101 2002-07-25 Akim Demaille <akim@epita.fr>
14102
14103 * src/output.c (prepare_tokens): Go up to ntokens, not ntokens + 1.

14112 * src/nullable.c, src/output.c, src/print.c, src/reader.c

15147

15171 (AT_DATA_HORIZONTAL_GRAMMAR): Respect the `%token ID NUM STRING'
15172 grammar.
15173 Use more modest sizes, as for the time being the parser does not

15178 stricter %token grammar.

15199
15200 * src/reader.c (parse_action): Don't store directly into the
15201 rule's action member: return the action as a string.

15224 * src/reader.c (grammar_rule_begin, previous_rule, current_rule):
15225 New.
15226 (readgram): Use them as replacement of inlined code, crule and
15227 crule1.

15240 prologue.

15248 assigning twice the same user number to a token, so that we can

15261
15262 2002-06-10 Akim Demaille <akim@epita.fr>
15263
15264 Remove `%thong' support as it is undocumented, unused, duplicates
15265 `%token's job, and creates useless e-mail traffic with people who
15266 want to know what it is, why it is undocumented, unused, and
15267 duplicates `%token's job.
15268
15269 * src/reader.c (parse_thong_decl): Remove.

15343 2002-05-27 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
15344

15458
15459 Kill GCC warnings.
15460
15461 * src/reduce.c (nonterminals_reduce): Don't loop over RITEM: loop

15487 * src/LR0.c (new_state, get_state): Instead of using the global

15491
15492 2002-05-06 Akim Demaille <akim@epita.fr>
15493
15494 * src/reader.c (packgram): No longer end `ritem' with a 0

15532 (prepare_rules): `i' is unsigned.
15533 `prhs', `rline', `r2' are unsigned int.

15538 to compute types instead of constant types.
15539 * tests/regression.at (Web2c Actions): Adjust.
15540

15639 `rule_length', which is more readable.
15640 Adjust callers.

15642 values of $$, $n and so forth, output invocation to b4_lhs_value,
15643 b4_lhs_location, b4_rhs_value, and b4_rhs_location.
15644 Note: this patch partially drops `semantic-parser' support: it
15645 always does `rule_length - n', where semantic parsers ought to
15646 always use `-n'.
15647 * data/bison.simple, data/bison.c++ (b4_lhs_value)
15648 (b4_lhs_location, b4_rhs_value, and b4_rhs_location: New.

15677
15678 * src/reader.c (copy_character): New function, used to output

15692 Reported by Paul Eggert.
15693
15694 2002-04-24 Robert Anisko <robert@lrde.epita.fr>
15695
15696 * tests/calc.at: Exercise prologue splitting.
15697
15698 * data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and

15709 `%union' has not yet been seen, pass post_prologue_obstack otherwise.
15710
15711 2002-04-23 Paul Eggert <eggert@twinsun.com>
15712
15713 * data/bison.simple: Remove unnecessary commentary and white
15714 space differences from 1_29-branch.
15715 Depend on YYERROR_VERBOSE, not defined (YYERROR_VERBOSE).

15718 YYSTACK_RELOCATE): Do not define if yyoverflow is defined, or
15719 if this is a C++ parser and YYSTYPE or YYLTYPE has nontrivial

15750
15751 2002-04-22 Akim Demaille <akim@epita.fr>
15752
15753 * src/reader.c (token_translations_init): 256 is now the default
15754 value for the error token, i.e., it will be assigned another
15755 number if the user assigned 256 to one of her tokens.
15756 (reader): Don't force 256 to error.
15757 * doc/bison.texinfo (Symbols): Adjust.
15758 * tests/torture.at (AT_DATA_HORIZONTAL_GRAMMAR)
15759 (AT_DATA_TRIANGULAR_GRAMMAR): Number the tokens as 1, 2, 3
15760 etc. instead of 10, 20, 30 (which was used to `jump' over error

15762
15763 2002-04-22 Akim Demaille <akim@epita.fr>
15764
15765 Propagate more token_number_t.

15768 (item_number_as_token_number): New.
15769 * src/output.c (GENERATE_OUTPUT_TABLE): New.

15782
15783 * doc/bison.texinfo (Actions): Make clear that `|' is not the same
15784 as Lex/Flex'.
15785 (Debugging): More details about enabling the debugging features.
15786 (Table of Symbols): Describe $$, $n, @$, and @n.
15787 Suggested by Tim Josling.
15788
15789 2002-04-19 Akim Demaille <akim@epita.fr>
15790
15791 * doc/bison.texinfo: Remove the uses of the obsolete @refill.
15792

15798 2002-04-09 Akim Demaille <akim@epita.fr>
15799
15800 * tests/calc.at (_AT_CHECK_CALC_ERROR): Receive as argument the
15801 full stderr, and strip it according to the bison options, instead
15802 of composing the error message from different bits.
15803 This makes it easier to check for several error messages.
15804 Adjust all the invocations.
15805 Add an invocation exercising the error token.
15806 Add an invocation demonstrating a stupid error message.
15807 (_AT_DATA_CALC_Y): Follow the GCS: initial column is 1, not 0.

15814 errtoken->number.
15815 * src/reader.c (reader): Don't specify the user token number (2)

15817 * src/gram.h (token_number_t): Move to...
15818 * src/symtab.h: here.
15819 (state_t.number): Is a token_number_t.
15820 * src/print.c, src/reader.c: Use undeftoken->number instead of
15821 hard coded 2.
15822 (Even though this 2 is not the same as above: the number of the
15823 undeftoken remains being 2, it is its user token number which
15824 might not be 2).
15825 * src/output.c (prepare_tokens): Rename the `maxtok' muscle with
15826 `user_token_number_max'.
15827 Output `undef_token_number'.
15828 * data/bison.simple, data/bison.c++: Use them.
15829 Be sure to map invalid yylex return values to
15830 `undef_token_number'. This saves us from gratuitous SEGV.

15847
15848 * src/gram.h (item_number_t): New, the type of item numbers in
15849 RITEM. Note that it must be able to code symbol numbers as
15850 positive number, and the negation of rule numbers as negative
15851 numbers.
15852 Adjust all dependencies (pretty many).
15853 * src/reduce.c (rule): Remove this `short *' pointer: use
15854 item_number_t.
15855 * src/system.h (MINSHORT, MAXSHORT): Remove.
15856 Include `limits.h'.
15857 Adjust dependencies to using SHRT_MAX and SHRT_MIN.
15858 (shortcpy): Remove.

15863 * tests/torture.at (Big triangle): Move the limit from 254 to
15864 500.
15865 * tests/regression.at (Web2c Actions): Ajust.
15866
15867 Trying with bigger grammars shows various phenomena: at 3000 (28Mb
15868 of grammar file) bison is killed by my system, at 2000 (12Mb) bison
15869 passes, but produces negative #line number, once fixed, GCC is
15870 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of
15871 C), it passes.
15872 * src/state.h (state_h): Code input lines on ints, not shorts.
15873

15998 * src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
15999
16000 2002-04-07 Akim Demaille <akim@epita.fr>

16029 creating `ruleset'.
16030
16031 As a result, now the rule 0, reducing to $axiom, is visible in the
16032 outputs. Adjust the test suite.

16051 `number' of the buckets too.

16073 lacking `+ 1' to nrules, Bison reported as useless a token if it
16074 was used solely to set the precedence of the last rule...
16075
16076 2002-04-07 Akim Demaille <akim@epita.fr>
16077
16078 * data/bison.c++, data/bison.simple: Don't output the current file

16359 * lib/tempname.c, lib/mkstemp.c, m4/mkstemp.m4: New, stolen from
16360 Fileutils 4.1.5.
16361 * configure.in: Invoke UTILS_FUNC_MKSTEMP.
16362 * src/output.c (output_skeleton): Use mkstemp to create a real
16363 temporary file.
16364 Move the filling of `skeleton' and its muscle to...
16365 (prepare): here.
16366 (output): Move the definition of the prologue muscle to...
16367 (prepare): here.
16368 * src/system.h (DEFAULT_TMPDIR): New.
16369
16370 2002-02-14 Paul Eggert <eggert@twinsun.com>
16371
16372 Remove the support for C++ namespace cleanliness; it was
16373 causing more problems than it was curing, since it didn't work
16374 properly on some nonstandard C++ compilers. This can wait
16375 for a proper C++ parser.
16376
16377 * NEWS: Document this.
16378 * doc/bison.texinfo (Bison Parser, Debugging): Remove special mention
16379 of C++, as it's treated like C now.
16380 * src/bison.simple (YYSTD): Remove.
16381 (YYSIZE_T, YYFPRINTF, YYPARSE_PARAM_ARG, YYPARSE_PARAM_DECL):
16382 Treat C++ just like Standard C instead of trying to support
16383 namespace cleanliness.
16384
16385 2002-02-14 Akim Demaille <akim@epita.fr>
16386
16387 * tests/regression.at (else): Adjust to Andreas' change.
16388
16389 2002-02-14 Akim Demaille <akim@epita.fr>
16390
16391 * lib/Makefile.am (EXTRA_DIST): Ship strnlen.c.
16392
16393 2002-02-13 Andreas Schwab <schwab@suse.de>
16394
16395 * src/output.c (output_rule_data): Don't output NULL, it might
16396 not be defined yet.
16397
16398 2002-02-11 Robert Anisko <robert@lrde.epita.fr>
16399
16400 * data/bison.c++ (YYDEBUG, YYERROR_VERBOSE): After the prologue.
16401 (Copyright notice): Update.
16402
16403 2002-02-11 Akim Demaille <akim@epita.fr>
16404
16405 * tests/regression.at (%nonassoc and eof): Don't include
16406 nonportable headers.
16407
16408 2002-02-08 Robert Anisko <robert@lrde.epita.fr>
16409
16410 * data/bison.c++: Correct error recovery. Make the user able to
16411 initialize the starting location.
16412
16413 2002-02-07 Akim Demaille <akim@epita.fr>
16414
16415 * tests/input.at: New.
16416
16417 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16418
16419 * data/bison.c++: Replace some direct m4 expansions by constants. Be
16420 more consistent when naming methods and variables. Put preprocessor
16421 directives around tables only needed for debugging.
16422
16423 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16424
16425 * data/bison.c++ (yy::b4_name::print_): New method, replaces yyprint in
16426 C++ parsers.
16427 (yy::b4_name::parse): Use print_.
16428
16429 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16430
16431 * data/bison.c++ (yy::b4_name::parse): Error recovery is back.
16432
16433 2002-02-07 Robert Anisko <robert@lrde.epita.fr>
16434
16435 * data/bison.c++ (yy::b4_name::error_): New method, replaces yyerror in
16436 C++ parsers.
16437 (yy::b4_name::parse): Build verbose error messages, and use error_.
16438
16439 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16440
16441 * data/bison.c++: Fix m4 quoting in comments.
16442
16443 2002-02-06 Robert Anisko <robert@lrde.epita.fr>
16444
16445 * data/bison.c++: Adjust the parser code. Fix some muscles that were
16446 not expanded by m4.
16447
16448 2002-02-05 Akim Demaille <akim@epita.fr>
16449
16450 * data/bison.c++: Adjust to the M4 back end.
16451 More is certainly needed.
16452
16453 2002-02-05 Akim Demaille <akim@epita.fr>
16454
16455 Give a try to M4 as a back end.
16456
16457 * lib/readpipe.c: New, from wdiff.
16458 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
16459 BISON_HAIRY.
16460 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
16461 specific values. Now it is m4 that performs the lookup.
16462 * src/parse-skel.y: Remove.
16463 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
16464 * src/output.c (actions_output, guards_output)
16465 (token_definitions_output): No longer keeps track of the output
16466 line number, hence remove the second argument.
16467 (guards_output): Check against the guard member of a rule, not the
16468 action member.
16469 Adjust callers.
16470 (output_skeleton): Don't look for the skeleton location, let m4 do
16471 that.
16472 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
16473 file will be used.
16474 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
16475 (prepare): Given that for the time being changesyntax is not
16476 usable in M4, rename the muscles using `-' to `_'.
16477 Define `defines_flag', `output_parser_name' and `output_header_name'.
16478 * src/output.h (actions_output, guards_output)
16479 (token_definitions_output): Adjust prototypes.
16480 * src/scan-skel.l: Instead of scanning the skeletons, it now
16481 processes the output of m4: `__oline__' and `#output'.
16482 * data/bison.simple: Adjust to be used by M4(sugar).
16483 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
16484 to date.
16485 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
16486 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
16487 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
16488 shamelessly stolen from CVS Autoconf.
16489
16490 2002-02-05 Akim Demaille <akim@epita.fr>
16491
16492 * lib/hash.c, lib/hash.h: Replace with Fileutils 4.1's version.
16493 * configure.in: Check for the declarations of free and malloc.
16494 * src/muscle_tab.c: Adjust.
16495
16496 2002-02-05 Akim Demaille <akim@epita.fr>
16497
16498 * src/muscle_tab.c (muscle_init): Don't default to NULL muscle
16499 which have no values.
16500
16501 2002-02-05 Akim Demaille <akim@epita.fr>
16502
16503 * src/bison.simple, src/bison.hairy, src/bison.c++: Move to...
16504 * data/: here.
16505
16506 2002-01-29 Paul Eggert <eggert@twinsun.com>
16507
16508 * src/bison.simple (YYSIZE_T): Do not define merely because
16509 YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
16510 On some platforms, <alloca.h> does not declare YYSTD (size_t).
16511
16512 2002-01-27 Akim Demaille <akim@epita.fr>
16513
16514 Fix `%nonassoc and eof'.
16515
16516 * src/state.c (errs_dup): Aaaah! The failure was due to bytes
16517 which were not properly copied! Replace
16518 memcpy (res->errs, src->errs, src->nerrs);
16519 with
16520 memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
16521 !!!
16522 * tests/regression.at (%nonassoc and eof): Adjust to newest
16523 Autotest: `.' is not in the PATH.
16524
16525 2002-01-27 Akim Demaille <akim@epita.fr>
16526
16527 * tests/sets.at (AT_EXTRACT_SETS): New.
16528 (Nullable): Use it.
16529 (Firsts): New.
16530
16531 2002-01-26 Akim Demaille <akim@epita.fr>
16532
16533 * tests/actions.at, tests/calc.at, tests/headers.at,
16534 * tests/torture.at: Adjust to the newest Autotest which no longer
16535 forces `.' in the PATH.
16536
16537 2002-01-25 Akim Demaille <akim@epita.fr>
16538
16539 * tests/regression.at (%nonassoc and eof): New.
16540 Suggested by Robert Anisko.
16541
16542 2002-01-24 Akim Demaille <akim@epita.fr>
16543
16544 Bison dumps core when trying to complain about broken input files.
16545 Reported by Cris van Pelt.
16546
16547 * src/lex.c (parse_percent_token): Be sure to set token_buffer.
16548 * tests/regression.at (Invalid input: 1, Invalid input: 2): Merge
16549 into...
16550 (Invalid inputs): Strengthen: exercise parse_percent_token.
16551
16552 2002-01-24 Robert Anisko <robert.anisko@epita.fr>
16553
16554 * src/Makefile.am: Add bison.c++.
16555 * src/bison.c++: New skeleton.
16556
16557 2002-01-21 Paolo Bonzini <bonzini@gnu.org>
16558
16559 * po/it.po: New.
16560
16561 2002-01-21 Kees Zeelenberg <kzlg@users.sourceforge.net>
16562
16563 * src/files.c (skeleton_find) [MSDOS]: Fix cp definition.
16564
16565 2002-01-20 Marc Autret <marc@gnu.org>
16566
16567 * src/files.c (compute_output_file_names): Fix
16568
16569 2002-01-20 Marc Autret <marc@gnu.org>
16570
16571 * tests/output.at: New test.
16572 * src/files.c (compute_base_names): Don't map extensions when
16573 the YACC flag is set, use defaults.
16574 Reported by Evgeny Stambulchik.
16575
16576 2002-01-20 Marc Autret <marc@gnu.org>
16577
16578 * src/system.h: Need to define __attribute__ away for non-GCC
16579 compilers as well (i.e., the vendor C compiler).
16580 Suggested by Albert Chin-A-Young.
16581
16582 2002-01-11 Tim Van Holder <tim.van.holder@pandora.be>
16583
16584 * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
16585 canonical definition.
16586 * src/system.h: Use the canonical definition for PARAMS (avoids
16587 a conflict with the macro from lib/hash.h).
16588
16589 2002-01-11 Akim Demaille <akim@epita.fr>
16590
16591 * configure.in: Use AC_FUNC_STRNLEN.
16592 Fixes the failures observed on AIX 4.3 by H.Merijn Brand.
16593
16594 2002-01-09 Akim Demaille <akim@epita.fr>
16595
16596 * src/files.c, src/files.h (output_infix): New.
16597 (tab_extension): Remove.
16598 (compute_base_names): Compute the former, drop the latter.
16599 * src/output.c (prepare): Insert the muscles `output-infix', and
16600 `output-suffix'.
16601 * src/parse-skel.y (string, string.1): New.
16602 (section.header): Use it.
16603 (section.yacc): Remove.
16604 (prefix): Remove too.
16605 * src/scan-skel.l: Adjust.
16606 * src/bison.simple, src/bison.hairy: Adjust.
16607
16608 2002-01-09 Akim Demaille <akim@epita.fr>
16609
16610 * configure.in (WERROR_CFLAGS): Compute it.
16611 * src/Makefile.am (CFLAGS): Pass it.
16612 * tests/atlocal.in (CFLAGS): Idem.
16613 * src/files.c: Fix a few warnings.
16614 (get_extension_index): Remove, unused.
16615
16616 2002-01-08 Akim Demaille <akim@epita.fr>
16617
16618 * src/getargs.c (AS_FILE_NAME): New.
16619 (getargs): Use it to convert DOSish file names.
16620 * src/files.c (base_name): Rename as full_base_name to avoid
16621 clashes with `base_name ()'.
16622 (filename_split): New.
16623 (compute_base_names): N-th rewrite, using filename_split.
16624
16625 2002-01-08 Akim Demaille <akim@epita.fr>
16626
16627 * lib/basename.c, lib/dirname.h, lib/dirname.c, lib/memrchr.c:
16628 New, stolen from the Fileutils 4.1.
16629 * lib/Makefile.am (libbison_a_SOURCES): Adjust.
16630 * configure.in: Check for the presence of memrchr, and of its
16631 prototype.
16632
16633 2002-01-07 Tim Van Holder <tim.van.holder@pandora.be>
16634
16635 * lib/hash.h (__P): Added definition for this macro.
16636 * src/Makefile.am: Add parse-skel.c and scan-skel.c to
16637 BUILT_SOURCES, to ensure they are generated first.
16638 * src/parse-skel.y: Use YYERROR_VERBOSE instead of
16639 %error-verbose to allow bootstrapping with bison 1.30x.
16640
16641 2002-01-06 Akim Demaille <akim@epita.fr>
16642
16643 * src/reader.c (parse_braces): Don't fetch the next char, the
16644 convention is to fetch on entry.
16645 * tests/torture.at (GNU Cim Grammar): Reintroduce their weird
16646 'switch' without a following semicolon.
16647 * tests/regression.at (braces parsing): New.
16648
16649 2002-01-06 Akim Demaille <akim@epita.fr>
16650
16651 Bison is dead wrong in its RR conflict reports.
16652
16653 * tests/torture.at (GNU Cim Grammar): New.
16654 * src/conflicts.c (count_rr_conflicts): Fix.
16655
16656 2002-01-06 Akim Demaille <akim@epita.fr>
16657
16658 Creating package.m4 from configure.ac causes too many problems.
16659
16660 * tests/Makefile.am (package.m4): Create it by hand,
16661 AC_CONFIG_TESTDIR no longer does in the most recent CVS Autoconf.
16662
16663 2002-01-06 Akim Demaille <akim@epita.fr>
16664
16665 * src/Makefile.am (bison_SOURCES): Add parse-skel.h and
16666 skeleton.h.
16667
16668 2002-01-04 Paul Eggert <eggert@twinsun.com>
16669
16670 * doc/bison.texinfo (Debugging):
16671 Remove YYSTDERR; it's no longer defined or used.
16672 Also, s/cstdio.h/cstdio/.
16673
16674 2002-01-03 Akim Demaille <akim@epita.fr>
16675
16676 * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
16677
16678 2002-01-03 Akim Demaille <akim@epita.fr>
16679
16680 * src/parse-skel.y (process_skeleton): Don't bind the parser's
16681 tracing code to --trace, wait for a better --trace option, with
16682 args.
16683
16684 2002-01-03 Akim Demaille <akim@epita.fr>
16685
16686 * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
16687 The ISO C++ standard is extremely clear about it: stderr is
16688 considered a macro, not a regular symbol (see table 94 `Header
16689 <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
16690 Therefore std:: does not apply to it. It still does with fprintf.
16691 Also, s/cstdio.h/cstdio/.
16692
16693 2002-01-03 Akim Demaille <akim@epita.fr>
16694
16695 * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
16696 for non system headers.
16697
16698 2002-01-02 Akim Demaille <akim@epita.fr>
16699
16700 Equip the skeleton chain with location tracking, runtime trace,
16701 pure parser and scanner.
16702
16703 * src/parse-skel.y: Request a pure parser, locations, and prefix
16704 renaming.
16705 (%union): Having several members with the same type does not help
16706 type mismatches, simplify.
16707 (YYPRINT, yyprint): New.
16708 (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
16709 (skel_error): this.
16710 Handle locations.
16711 * src/scan-skel.l: Adjust to these changes.
16712 * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
16713 (LOCATION_PRINT, skel_control_t): New.
16714
16715 2001-12-30 Akim Demaille <akim@epita.fr>
16716
16717 * src/parse-skel.y: Get rid of the shift/reduce conflict:
16718 replace `gb' with BLANKS.
16719 * src/scan-skel.l: Adjust.
16720
16721 2001-12-30 Akim Demaille <akim@epita.fr>
16722
16723 * src/system.h: We don't need nor want bcopy.
16724 Throw away MS-DOS crap: we don't need getpid.
16725 * configure.in: We don't need strndup. It was even causing
16726 problems: because Flex includes the headers *before* us,
16727 _GNU_SOURCE is not defined by config.h, and therefore strndup was
16728 not visible.
16729 * lib/xstrndup.c: New.
16730 * src/scan-skel.l: Use it.
16731 Be sure to initialize yylval.muscle member when scanning a MUSCLE.
16732 * src/parse-skel.y: Use %directives instead of #defines.
16733
16734 2001-12-30 Akim Demaille <akim@epita.fr>
16735
16736 * src/skeleton.h: New.
16737 * src/output.c (output_parser, output_master_parser): Remove, dead
16738 code.
16739 * src/output.h (get_lines_number, actions_output, guards_output)
16740 (token_definitions_output): Prototype them.
16741 * src/parse-skel.y: Add the license notice.
16742 Include output.h and skeleton.h.
16743 (process_skeleton): Returns void, and takes a single parameter.
16744 * src/scan-skel.l: Add the license notice.
16745 Include skeleton.h.
16746 Don't use %option yylineno: it seems that then Flex imagines
16747 REJECT has been used, and therefore it won't reallocate its
16748 buffers (which makes no other sense to me than a bug). It results
16749 in warnings for `unused: yy_flex_realloc'.
16750
16751 2001-12-30 Robert Anisko <robert.anisko@epita.fr>
16752
16753 * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16754 (MUSCLE_INSERT_PREFIX): ...to there.
16755 * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
16756 (MUSCLE_INSERT_PREFIX): Move from here...
16757
16758 * src/bison.hairy: Add a section directive. Put braces around muscle
16759 names. This parser skeleton is still broken, but Bison should not
16760 choke on a bad muscle 'syntax'.
16761 * src/bison.simple: Add a section directive. Put braces around muscle
16762 names.
16763
16764 * src/files.h (strsuffix, stringappend): Add declarations.
16765 (tab_extension): Add declaration.
16766 (short_base_name): Add declaration.
16767
16768 * src/files.c (strsuffix, stringappend): No longer static. These
16769 functions are used in the skeleton parser.
16770 (tab_extension): New.
16771 (compute_base_names): Use the computations done in this function
16772 to guess if the generated parsers should have '.tab' in their
16773 names.
16774 (short_base_name): No longer static.
16775
16776 * src/output.c (output_skeleton): New.
16777 (output): Disable call to output_master_parser, and give a try to
16778 a new skeleton handling system.
16779 (guards_output, actions_output): No longer static.
16780 (token_definitions_output, get_lines_number): No longer static.
16781
16782 * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
16783
16784 * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
16785 parse-skel.y.
16786
16787 * src/parse-skel.y: New file.
16788 * src/scan-skel.l: New file.
16789
16790 2001-12-29 Akim Demaille <akim@epita.fr>
16791
16792 %name-prefix is broken.
16793
16794 * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
16795 Adjust all dependencies.
16796 * tests/headers.at (export YYLTYPE): Strengthen this test: use
16797 %name-prefix.
16798
16799 Renaming yylval but not yylloc is not consistent. Now we do.
16800
16801 * src/bison.simple: Prefix yylloc if used.
16802 * doc/bison.texinfo (Decl Summary): Document that.
16803
16804 2001-12-29 Akim Demaille <akim@epita.fr>
16805
16806 * doc/bison.texinfo: Promote `%long-directive' over
16807 `%long_directive'.
16808 Remove all references to fixed-output-files, yacc is enough.
16809
16810 2001-12-29 Akim Demaille <akim@epita.fr>
16811
16812 * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
16813 user prologue. These are defaults.
16814 * tests/actions.at (Mid-rule actions): Make sure the user can
16815 define YYDEBUG and YYERROR_VERBOSE.
16816
16817 2001-12-29 Akim Demaille <akim@epita.fr>
16818
16819 * src/output.c (header_output): Don't forget to export YYLTYPE and
16820 yylloc.
16821 * tests/headers.at (export YYLTYPE): New, make sure it does.
16822 * tests/regression.at (%union and --defines, Invalid CPP headers):
16823 Move to...
16824 * tests/headers.at: here.
16825
16826 2001-12-29 Akim Demaille <akim@epita.fr>
16827
16828 * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
16829
16830 2001-12-29 Akim Demaille <akim@epita.fr>
16831
16832 * tests/actions.at (Mid-rule actions): Output on a single line
16833 instead of several.
16834
16835 2001-12-29 Akim Demaille <akim@epita.fr>
16836
16837 * doc/bison.texinfo: Formatting changes.
16838
16839 2001-12-29 Akim Demaille <akim@epita.fr>
16840
16841 Don't store the token defs in a muscle, just be ready to output it
16842 on command. Now possible via `symbols'. Fixes a memory leak.
16843
16844 * src/output.c (token_definitions_output): New.
16845 (output_parser, header_output): Use it.
16846 * src/reader.c (symbols_save): Remove.
16847
16848 2001-12-29 Akim Demaille <akim@epita.fr>
16849
16850 * src/bison.simple: Do not provide a default for YYSTYPE and
16851 YYLTYPE before the user's prologue. Otherwise it's hardly... a
16852 default.
16853
16854 2001-12-29 Akim Demaille <akim@epita.fr>
16855
16856 Mid-rule actions are simply... ignored!
16857
16858 * src/reader.c (readgram): Be sure to attach mid-rule actions to
16859 the empty-rule associated to the dummy symbol, not to the host
16860 rule.
16861 * tests/actions.at (Mid-rule actions): New.
16862
16863 2001-12-29 Akim Demaille <akim@epita.fr>
16864
16865 Memory leak.
16866
16867 * src/reader.c (reader): Free grammar.
16868
16869 2001-12-29 Akim Demaille <akim@epita.fr>
16870
16871 Memory leak.
16872
16873 * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
16874 since it allocates it for each state, although only one is needed.
16875 (allocate_storage): Do it here.
16876
16877 2001-12-29 Akim Demaille <akim@epita.fr>
16878
16879 * src/options.h, src/options.c (create_long_option_table): Rename
16880 as...
16881 (long_option_table_new): this, with a clearer prototype.
16882 (percent_table): Remove, unused,
16883 * src/getargs.c (getargs): Adjust.
16884
16885 2001-12-29 Akim Demaille <akim@epita.fr>
16886
16887 * src/LR0.c, src/conflicts.c, src/lalr.c, src/lalr.h, src/output.c
16888 * src/print.c, src/print_graph.c, src/state.h: Rename state_table
16889 as states.
16890
16891 2001-12-29 Akim Demaille <akim@epita.fr>
16892
16893 * src/lalr.c (build_relations): Rename `states' as `states1'.
16894 Sorry, I don't understand exactly what it is, no better name...
16895
16896 2001-12-29 Akim Demaille <akim@epita.fr>
16897
16898 * src/closure.c, src/conflicts.c, src/derives.c, src/gram.c
16899 * src/gram.h, src/lalr.c, src/nullable.c, src/output.c, src/print.c
16900 * src/print_graph.c, src/reader.c, src/reduce.c: Rename rule_table
16901 as rules.
16902
16903 2001-12-29 Akim Demaille <akim@epita.fr>
16904
16905 * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
16906 ago.
16907
16908 2001-12-29 Akim Demaille <akim@epita.fr>
16909
16910 * src/reader.c, src/reader.h (user_toknums): Remove.
16911 Adjust all users to use symbols[i]->user_token_number.
16912
16913 2001-12-29 Akim Demaille <akim@epita.fr>
16914
16915 * src/gram.c, src/gram.h (sprec, sassoc): Remove.
16916 Adjust all users to use symbols[i]->prec or ->assoc.
16917
16918 2001-12-29 Akim Demaille <akim@epita.fr>
16919
16920 * src/reader.c, src/reader.h (tags): Remove.
16921 Adjust all users to use symbols[i]->tag.
16922
16923 2001-12-29 Akim Demaille <akim@epita.fr>
16924
16925 * src/gram.h, src/gram.c (symbols): New, similar to state_table
16926 and rule_table.
16927 * src/reader.c (packsymbols): Fill this table.
16928 Drop sprec.
16929 * src/conflicts.c (resolve_sr_conflict): Adjust.
16930 * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
16931 single table.
16932 Use symbols[i]->tag instead of tags[i].
16933
16934 2001-12-29 Akim Demaille <akim@epita.fr>
16935
16936 * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
16937 In addition, put a comment in there, to replace...
16938 * tests/regression.at (%union and C comments): Remove.
16939
16940 2001-12-29 Akim Demaille <akim@epita.fr>
16941
16942 * tests/regression.at (Web2c Actions): Blindly move the actual
16943 output as expected output. The contents *seem* right to me, but I
16944 can't pretend reading perfectly parser tables... Nonetheless, all
16945 the other tests pass correctly, the table look OK, even though the
16946 presence of `$axiom' is to be noted: AFAICS it is useless (but
16947 harmless).
16948
16949 2001-12-29 Akim Demaille <akim@epita.fr>
16950
16951 * src/reader.c (readgram): Don't add the rule 0 if there were no
16952 rules read. In other words, add it _after_ having performed
16953 grammar sanity checks.
16954 Fixes the `tests/regression.at (Invalid input: 1)' Failure.
16955
16956 2001-12-29 Akim Demaille <akim@epita.fr>
16957
16958 * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
16959 visible, and some states have now a different number.
16960
16961 2001-12-29 Akim Demaille <akim@epita.fr>
16962
16963 * src/reader.c (readgram): Bind the initial rule's lineno to that
16964 of the first rule.
16965 * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
16966 (Solved SR Conflicts): Adjust rule 0's line number.
16967
16968 2001-12-29 Akim Demaille <akim@epita.fr>
16969
16970 Fix the `GAWK Grammar' failure.
16971
16972 * src/LR0.c (final_state): Initialize to -1 so that we do compute
16973 the reductions of the first state which was mistakenly confused
16974 with the final state because precisely final_state was initialized
16975 to 0.
16976 * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
16977 now noticed by Bison.
16978 * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
16979 have a reduction on $default.
16980
16981 2001-12-29 Akim Demaille <akim@epita.fr>
16982
16983 * src/gram.c (ritem_print): Be sure to subtract 1 when displaying
16984 rule line numbers.
16985 * src/closure.c (print_closure): Likewise.
16986 * src/derives.c (print_derives): Likewise.
16987 * tests/sets.at (Nullable): Adjust: the rule numbers are correct
16988 now.
16989
16990 2001-12-29 Akim Demaille <akim@epita.fr>
16991
16992 * src/lalr.c (lookaheads_print): New.
16993 (lalr): Call it when --trace-flag.
16994 * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
16995 are dumped.
16996
16997 2001-12-29 Akim Demaille <akim@epita.fr>
16998
16999 * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
17000 when walking through ritem, even via rule->rhs.
17001 * src/reduce.c (dump_grammar, useful_production, reduce_output)
17002 (useful_production, useless_nonterminals): Likewise.
17003 (reduce_grammar_tables): Likewise, plus update nritems.
17004 * src/nullable.c (set_nullable): Likewise.
17005 * src/lalr.c (build_relations): Likewise.
17006 * tests/sets.at (Nullable): Adjust.
17007 Fortunately, now, the $axiom is no longer nullable.
17008
17009 2001-12-29 Akim Demaille <akim@epita.fr>
17010
17011 * src/LR0.c (generate_states): Use nritems, not nitems, nor using
17012 the 0-sentinel.
17013 * src/gram.c (ritem_longest_rhs): Likewise.
17014 * src/reduce.c (nonterminals_reduce): Likewise.
17015 * src/print_graph.c (print_graph): Likewise.
17016 * src/output.c (output_rule_data): Likewise.
17017 * src/nullable.c (set_nullable): Likewise.
17018
17019 2001-12-29 Akim Demaille <akim@epita.fr>
17020
17021 * src/output.c: Comment changes.
17022
17023 2001-12-27 Paul Eggert <eggert@twinsun.com>
17024
17025 * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
17026 cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
17027 Sparc, as they were causing more porting problems than the
17028 (minor) performance improvement was worth.
17029
17030 Also, catch up with 1.31's YYSTD.
17031
17032 2001-12-27 Akim Demaille <akim@epita.fr>
17033
17034 * src/output.c (output_gram): Rely on nritems, not the
17035 0-sentinel. See below.
17036 Use -1 as separator, not 0.
17037 * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
17038 Rely on -1 as separator in yyrhs, instead of 0.
17039 * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
17040 twice `Now at end of input', therefore there are two lines less to
17041 expect.
17042
17043 2001-12-27 Akim Demaille <akim@epita.fr>
17044
17045 * tests/regression.at (Unresolved SR Conflicts):
17046 (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
17047 below.
17048
17049 2001-12-27 Akim Demaille <akim@epita.fr>
17050
17051 * src/LR0.c (new_state): Recognize the final state by the fact it
17052 is reached by eoftoken.
17053 (insert_start_shifting_state, insert_eof_shifting_state)
17054 (insert_accepting_state, augment_automaton): Remove, since now
17055 these states are automatically computed from the initial state.
17056 (generate_states): Adjust.
17057 * src/print.c: When reporting a rule number to the user, substract
17058 1, so that the axiom rule is rule 0, and the first user rule is 1.
17059 * src/reduce.c: Likewise.
17060 * src/print_graph.c (print_core): For the time being, just as for
17061 the report, depend upon --trace-flags to dump the full set of
17062 items.
17063 * src/reader.c (readgram): Once the grammar read, insert the rule
17064 0: `$axiom: START-SYMBOL $'.
17065 * tests/set.at: Adjust: rule 0 is now displayed, and since the
17066 number of the states has changed (the final state is no longer
17067 necessarily the last), catch up.
17068
17069 2001-12-27 Akim Demaille <akim@epita.fr>
17070
17071 Try to make the use of the eoftoken valid. Given that its value
17072 is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
17073 is used instead of > 0 where appropriate, (ii), depend upon nritems
17074 instead of the 0-sentinel.
17075
17076 * src/gram.h, src/gram.c (nritems): New.
17077 Expected to be duplication of nitems, but for the time being...
17078 * src/reader.c (packgram): Assert nritems and nitems are equal.
17079 * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
17080 * src/closure.c (print_closure, print_fderives): Likewise.
17081 * src/gram.c (ritem_print): Likewise.
17082 * src/print.c (print_core, print_grammar): Likewise.
17083 * src/print_graph.c: Likewise.
17084
17085 2001-12-27 Akim Demaille <akim@epita.fr>
17086
17087 * src/main.c (main): If there are complains after grammar
17088 reductions, then output the report anyway if requested, then die.
17089 * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
17090 * src/reader.c (eoftoken): New.
17091 (parse_token_decl): If the token being defined has value `0', it
17092 is the eoftoken.
17093 (packsymbols): No longer hack `tags' to insert `$' by hand.
17094 Be sure to preserve the value of the eoftoken.
17095 (reader): Make sure eoftoken is defined.
17096 Initialize nsyms to 0: now eoftoken is created just like the others.
17097 * src/print.c (print_grammar): Don't special case the eof token.
17098 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
17099 lie anyway, albeit pleasant.
17100 * tests/calc.at: Exercise error messages with eoftoken.
17101 Change the grammar so that empty input is invalid.
17102 Adjust expectations.
17103 When yyungeting, be sure to use a valid yylloc: use last_yylloc.
17104
17105 2001-12-27 Akim Demaille <akim@epita.fr>
17106
17107 * configure.in: Check the protos of strchr ans strspn.
17108 Replace strchr if needed.
17109 * src/system.h: Provide the protos of strchr, strspn and memchr if
17110 missing.
17111 * lib/strchr.c: New.
17112 * src/reader.c (symbols_save): Use strchr.
17113
17114 2001-12-27 Akim Demaille <akim@epita.fr>
17115
17116 * src/print.c, src/print_graph.c (escape): New.
17117 Use it to quote the TAGS outputs.
17118 * src/print_graph.c (print_state): Now errors are in red, and
17119 reductions in green.
17120 Prefer high to wide: output the state number on a line of its own.
17121
17122 2001-12-27 Akim Demaille <akim@epita.fr>
17123
17124 * src/state.h, src/state.c (reductions_new): New.
17125 * src/LR0.c (set_state_table): Let all the states have a
17126 `reductions', even if reduced to 0.
17127 (save_reductions): Adjust.
17128 * src/lalr.c (initialize_LA, initialize_lookaheads): Adjust.
17129 * src/print.c (print_reductions, print_actions): Adjust.
17130 * src/output.c (action_row): Adjust.
17131
17132 2001-12-27 Akim Demaille <akim@epita.fr>
17133
17134 * src/state.h, src/state.c (errs_new, errs_dup): New.
17135 * src/LR0.c (set_state_table): Let all the states have an errs,
17136 even if reduced to 0.
17137 * src/print.c (print_errs, print_reductions): Adjust.
17138 * src/output.c (output_actions, action_row): Adjust.
17139 * src/conflicts.c (resolve_sr_conflict): Adjust.
17140
17141 2001-12-27 Akim Demaille <akim@epita.fr>
17142
17143 * src/lalr.c (set_goto_map, initialize_F): Use SHIFT_SYMBOL.
17144
17145 2001-12-27 Akim Demaille <akim@epita.fr>
17146
17147 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
17148 * src/print.c: here.
17149 (lookaheadset, shiftset): New, used as additional storage by
17150 print_reductions.
17151 (print_results): Adjust.
17152 (print_shifts, print_gotos, print_errs): New, extracted from...
17153 (print_actions): here.
17154 * src/print_graph.c (print_actions): Remove dead code.
17155
17156 2001-12-27 Akim Demaille <akim@epita.fr>
17157
17158 * src/reader.c (copy_dollar, copy_at): Better checking of `n' in
17159 `$n' and `@n'.
17160
17161 2001-12-27 Akim Demaille <akim@epita.fr>
17162
17163 * src/lalr.c (add_lookback_edge): Use state_t instead of ints.
17164 (build_relations): Adjust.
17165
17166 2001-12-27 Akim Demaille <akim@epita.fr>
17167
17168 * src/lalr.c (set_goto_map): Remove a wrong but benign loop
17169 duplication.
17170
17171 2001-12-27 Akim Demaille <akim@epita.fr>
17172
17173 * src/reader.c (packgram): Catch nitems overflows.
17174
17175 2001-12-27 Akim Demaille <akim@epita.fr>
17176
17177 * src/files.c, src/files.h (guard_obstack): Remove.
17178 * src/output.c (output): Adjust.
17179 * src/reader.c (parse_braces): New, factoring...
17180 (copy_action, copy_guard): these two which are renamed as...
17181 (parse_action, parse_guard): these.
17182 As a voluntary consequence, using braces around guards is now
17183 mandatory.
17184
17185 2001-12-27 Akim Demaille <akim@epita.fr>
17186
17187 * src/gram.h (rule_t): `guard' and `guard_line' are new members.
17188 * src/reader.c (symbol_list): `guard' and `guard_line' are new
17189 members.
17190 (symbol_list_new): Adjust.
17191 (copy_action): action_line is the first line, not the last.
17192 (copy_guard): Just as for actions, store the `action' only, not
17193 the switch/case/break flesh.
17194 Don't parse the user action that might follow the guard, let...
17195 (readgram): do it, i.e., now, there can be an action after a
17196 guard.
17197 In other words the guard is just explicitly optional.
17198 (packgram): Adjust.
17199 * src/output.c (guards_output): New.
17200 (output_parser): Call it when needed.
17201 (output): Also free the guard and attrs obstacks.
17202 * src/files.c, src/files.h (obstack_save): Remove.
17203 (output_files): Remove.
17204 As a result, if one needs the former `.act' file, using an
17205 appropriate skeleton which requires actions and guards is now
17206 required.
17207 * src/main.c (main): Adjust.
17208 * tests/semantic.at: New.
17209 * tests/regression.at: Use `input.y' as input file name.
17210 Avoid 8+3 problems by requiring input.c when the test needs the
17211 parser.
17212
17213 2001-12-27 Akim Demaille <akim@epita.fr>
17214
17215 * src/reader.c (symbol_list_new): Be sure to initialize all the
17216 fields.
17217
17218 2001-12-27 Akim Demaille <akim@epita.fr>
17219
17220 All the hacks using a final pseudo state are now useless.
17221
17222 * src/LR0.c (set_state_table): state_table holds exactly nstates.
17223 * src/lalr.c (nLA): New.
17224 (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
17225 instead of lookaheadsp from the pseudo state (nstate + 1).
17226
17227 2001-12-27 Akim Demaille <akim@epita.fr>
17228
17229 * src/output.c (action_row, token_actions): Use a state_t instead
17230 of a integer, and nlookaheads instead of the following state's
17231 lookaheadsp.
17232
17233 2001-12-27 Akim Demaille <akim@epita.fr>
17234
17235 * src/conflicts.c (log_resolution, flush_shift)
17236 (resolve_sr_conflict, set_conflicts, solve_conflicts)
17237 (count_sr_conflicts, count_rr_conflicts, conflicts_output)
17238 (conflicts_print, print_reductions): Use a state_t instead of an
17239 integer when referring to a state.
17240 As much as possible, depend upon nlookaheads, instead of the
17241 `lookaheadsp' member of the following state (since lookaheads of
17242 successive states are successive, the difference between state n + 1
17243 and n served as the number of lookaheads for state n).
17244 * src/lalr.c (add_lookback_edge): Likewise.
17245 * src/print.c (print_core, print_actions, print_state)
17246 (print_results): Likewise.
17247 * src/print_graph.c (print_core, print_actions, print_state)
17248 (print_graph): Likewise.
17249 * src/conflicts.h: Adjust.
17250
17251 2001-12-27 Akim Demaille <akim@epita.fr>
17252
17253 * src/bison.hairy: Formatting/comment changes.
17254 ANSIfy.
17255 Remove `register' indications.
17256 Add plenty of `static'.
17257
17258 2001-12-27 Akim Demaille <akim@epita.fr>
17259
17260 * src/output.c (prepare): Drop the muscle `ntbase' which
17261 duplicates ntokens.
17262 * src/bison.simple: Formatting/comment changes.
17263 Use YYNTOKENS only, which is documented, but not YYNTBASE, which
17264 is an undocumented synonym.
17265
17266 2001-12-22 Akim Demaille <akim@epita.fr>
17267
17268 * src/output.c (output_table_data): Change the prototype to use
17269 `int' for array ranges: some invocations do pass an int, not a
17270 short.
17271 Reported by Wayne Green.
17272
17273 2001-12-22 Akim Demaille <akim@epita.fr>
17274
17275 Some actions of web2c.y are improperly triggered.
17276 Reported by Mike Castle.
17277
17278 * src/lalr.c (traverse): s/F (i)[k] = F (j)[k]/F (j)[k] = F (i)[k]/.
17279 * tests/regression.at (Web2c): Rename as...
17280 (Web2c Report): this.
17281 (Web2c Actions): New.
17282
17283 2001-12-22 Akim Demaille <akim@epita.fr>
17284
17285 Reductions in web2c.y are improperly reported.
17286 Reported by Mike Castle.
17287
17288 * src/conflicts.c (print_reductions): Fix.
17289 * tests/regression.at (Web2c): New.
17290
17291 2001-12-18 Akim Demaille <akim@epita.fr>
17292
17293 Some host fail on `assert (!"foo")', which expands to
17294 ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
17295 Reported by Nelson Beebee.
17296
17297 * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
17298 `#define it_succeeded 0' and `assert (it_succeeded)'.
17299
17300 2001-12-17 Marc Autret <autret_m@epita.fr>
17301
17302 * src/bison.simple: Don't hard code the skeleton line and filename.
17303 * src/output.c (output_parser): Rename 'line' as 'output_line'.
17304 New line counter 'skeleton_line' (skeleton-line muscle).
17305
17306 2001-12-17 Paul Eggert <eggert@twinsun.com>
17307
17308 * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document that
17309 YYDEBUG must be defined to a nonzero value.
17310
17311 * src/bison.simple (yytname): Do not assume that the user defines
17312 YYDEBUG to a properly parenthesized expression.
17313
17314 2001-12-17 Akim Demaille <akim@epita.fr>
17315
17316 * src/state.h (state_t): Rename lookaheads as lookaheadsp.
17317 nlookaheads is a new member.
17318 Adjust all users.
17319 * src/lalr.h (nlookaheads): Remove this orphan declaration.
17320 * src/lalr.c (initialize_lookaheads): Set nlookaheads for each
17321 state.
17322
17323 2001-12-17 Akim Demaille <akim@epita.fr>
17324
17325 * src/files.h, src/files.c (open_files, close_files): Remove.
17326 * src/main.c (main): Don't open/close files, nor invoke lex_free,
17327 let...
17328 * src/reader.c (reader): Do it.
17329
17330 2001-12-17 Akim Demaille <akim@epita.fr>
17331
17332 * src/conflicts.c (print_reductions): Formatting changes.
17333
17334 2001-12-17 Akim Demaille <akim@epita.fr>
17335
17336 * src/conflicts.c (flush_shift): Also adjust lookaheadset.
17337 (flush_reduce): New.
17338 (resolve_sr_conflict): Adjust.
17339
17340 2001-12-17 Akim Demaille <akim@epita.fr>
17341
17342 * src/output.c (output_obstack): Be static and rename as...
17343 (format_obstack): this, to avoid any confusion with files.c's
17344 output_obstack.
17345 * src/reader.h (muscle_obstack): Move to...
17346 * src/output.h: here, since it's defined in output.c.
17347
17348 2001-12-17 Akim Demaille <akim@epita.fr>
17349
17350 * src/output.c (action_row, save_column, default_goto)
17351 (sort_actions, matching_state, pack_vector): Better variable
17352 locality.
17353
17354 2001-12-17 Akim Demaille <akim@epita.fr>
17355
17356 * src/output.c: Various formatting changes.
17357
17358 2001-12-17 Akim Demaille <akim@epita.fr>
17359
17360 * src/files.c (output_files): Free the output_obstack.
17361 * src/main.c (main): Call print and print_graph conditionally.
17362 * src/print.c (print): Work unconditionally.
17363 * src/print_graph.c (print_graph): Work unconditionally.
17364 * src/conflicts.c (log_resolution): Output only if verbose_flag.
17365
17366 2001-12-16 Marc Autret <autret_m@epita.fr>
17367
17368 * src/output.c (actions_output): Fix. When we use %no-lines,
17369 there is one less line per action.
17370
17371 2001-12-16 Marc Autret <autret_m@epita.fr>
17372
17373 * src/bison.simple: Remove a useless #line directive.
17374 s/#line %%line %%skeleton/#line %%line "%%parser-file-name"/'.
17375 * src/output.c (get_lines_number): New.
17376 (output_parser): Adjust, now takes care about the lines of a
17377 output muscles.
17378 Fix line numbering.
17379 (actions_output): Computes the number of lines taken by actions.
17380 (output_master_parser): Insert new skeleton which is the name of
17381 the output parser file name.
17382
17383 2001-12-15 Marc Autret <autret_m@epita.fr>
17384
17385 * src/bison.simple [YYERROR_VERBOSE]: Restore backward compatibility.
17386
17387 2001-12-15 Marc Autret <autret_m@epita.fr>
17388
17389 * src/output.c (output_gram): Keep track of the hairy one.
17390
17391 2001-12-15 Akim Demaille <akim@epita.fr>
17392
17393 Make `make distcheck' work.
17394
17395 * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
17396 system.h which uses libgettext.h.
17397
17398 2001-12-15 Akim Demaille <akim@epita.fr>
17399
17400 * src/nullable.c (set_nullable): Useless rules must be skipped,
17401 otherwise, since we range over their symbols, we might look at a
17402 nonterminal which no longer ``exists'', i.e., it is not counted in
17403 `nvars', hence we overflow our arrays.
17404
17405 2001-12-15 Akim Demaille <akim@epita.fr>
17406
17407 The header can also be produced directly, without any obstack!
17408 Yahoo!
17409
17410 * src/files.c, src/files.h (defines_obstack): Remove.
17411 (compute_header_macro): Global.
17412 (defines_obstack_save): Remove.
17413 * src/reader.c (parse_union_decl): No longer output to
17414 defines_obstack: its content can be found in the `stype' muscle
17415 anyway.
17416 (output_token_translations): Merge into...
17417 (symbols_output): this.
17418 Rename as...
17419 (symbols_save): this.
17420 (reader): Adjust.
17421 * src/output.c (header_output): New.
17422 (output): Call it.
17423
17424 2001-12-15 Akim Demaille <akim@epita.fr>
17425
17426 * src/reader.c (parse_union_decl): Instead of handling two obstack
17427 simultaneously, use one to define the `stype' muscle, and use the
17428 value of the latter to fill defines_obstack.
17429 (copy_comment): Remove.
17430 (copy_comment2): Work for a single obstack.
17431 Rename as...
17432 (copy_comment): this.
17433
17434 2001-12-15 Akim Demaille <akim@epita.fr>
17435
17436 * src/lex.c, src/lex.h (xgetc): No longer static.
17437 * src/reader.c (parse_union_decl): Revamp.
17438
17439 2001-12-15 Akim Demaille <akim@epita.fr>
17440
17441 Still making progress in separating Bison into (i) input, (ii)
17442 process, (iii) output: now we can directly output the parser file
17443 without using table_obstack at all.
17444
17445 * src/files.c, src/files.h (table_obstack): Bye bye.
17446 (parser_file_name): New.
17447 * src/files.c (compute_output_file_names): Compute it.
17448 * src/output.c (actions_output, output_parser)
17449 (output_master_parser): To a file instead of an obstack.
17450
17451 2001-12-15 Akim Demaille <akim@epita.fr>
17452
17453 Attach actions to rules, instead of pre-outputting them to
17454 actions_obstack.
17455
17456 * src/gram.h (rule_t): action and action_line are new members.
17457 * src/reader.c (symbol_list): Likewise.
17458 (copy_action): Save the actions within the rule.
17459 (packgram): Save them in rule_table.
17460 * src/output.c (actions_output): New.
17461 (output_parser): Use it on `%%actions'.
17462 (output_rule_data): Don't free rule_table.
17463 (output): Do it.
17464 (prepare): Don't save the `action' muscle.
17465 * src/bison.simple: s/%%action/%%actions/.
17466
17467 2001-12-15 Akim Demaille <akim@epita.fr>
17468
17469 * src/reader.c (copy_action): When --yacc, don't append a `;'
17470 to the user action: let it fail if lacking.
17471 Suggested by Arnold Robbins and Tom Tromey.
17472
17473 2001-12-14 Akim Demaille <akim@epita.fr>
17474
17475 * src/lex.c (literalchar): Simply return the char you decoded, non
17476 longer mess around with obstacks and int pointers.
17477 Adjust all callers.
17478
17479 2001-12-14 Akim Demaille <akim@epita.fr>
17480
17481 * src/lex.c (literalchar): Don't escape the special characters,
17482 just decode them, and keep them as char (before, eol was output as
17483 the 2 char string `\n' etc.).
17484 * src/output.c (output_rule_data): Use quotearg to output the
17485 token strings.
17486
17487 2001-12-13 Paul Eggert <eggert@twinsun.com>
17488
17489 * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
17490 Do not infringe on the global user namespace when using C++.
17491 (YYFPRINTF, YYSTDERR): New macros, needed for the above.
17492 All uses of `fprintf' and `stderr' changed.
17493
17494 * doc/bison.texinfo: Document YYFPRINTF, YYSTDERR.
17495
17496 2001-12-13 Akim Demaille <akim@epita.fr>
17497
17498 The computation of nullable is broken: it doesn't handle empty
17499 RHS's properly.
17500
17501 * tests/torture.at (GNU AWK Grammar): New.
17502 * tests/sets.at (Nullable): New.
17503 * src/nullable.c (set_nullable): Instead of blindly looping over
17504 `ritems', loop over the rules, and then over their rhs's.
17505
17506 Work around Autotest bugs.
17507
17508 * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
17509 frame, because Autotest understand lines starting with a `+' as
17510 traces from the shell. Then, they are not processed properly.
17511 Admittedly an Autotest bug, but we don't have time to wait for
17512 Autotest to catch up.
17513 * tests/regression.at (Broken Closure): Adjust to the new table
17514 frames.
17515 Move to...
17516 * tests/sets.at: here.
17517
17518 2001-12-13 Akim Demaille <akim@epita.fr>
17519
17520 * src/closure.c (closure): Use nrules instead of playing tricks
17521 with BITS_PER_WORD.
17522
17523 2001-12-13 Akim Demaille <akim@epita.fr>
17524
17525 * src/print.c (print_actions): Output the handling of `$' as the
17526 traces do: shifting the token EOF. Before EOF was treated as a
17527 nonterminal.
17528 * tests/regression.at: Adjust some tests.
17529 * src/print_graph.c (print_core): Complete the set of items via
17530 closure. The next-to-final and final states are still unsatisfying,
17531 but that's to be addressed elsewhere.
17532 No longer output the rule numbers, but do output the state number.
17533 A single loop for the shifts + gotos is enough, but picked a
17534 distinct color for each.
17535 (print_graph): Initialize and finalize closure.
17536
17537 2001-12-13 Akim Demaille <akim@epita.fr>
17538
17539 * src/reader.c (readgram): Remove dead code, an strip useless
17540 braces.
17541 (get_type): Remove, unused.
17542
17543 2001-12-12 Akim Demaille <akim@epita.fr>
17544
17545 * src/complain.h, src/complain.c: Remove error_one_per_line, rely
17546 on that of lib/error.c.
17547
17548 2001-12-12 Akim Demaille <akim@epita.fr>
17549
17550 Some hosts don't like `/' in includes.
17551
17552 * src/system.h: Include libgettext.h without qualifying the path.
17553 * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
17554 $(top_srcdir).
17555
17556 2001-12-11 Marc Autret <autret_m@epita.fr>
17557
17558 * src/output.c (output_parser): Remove useless muscle.
17559
17560 2001-12-11 Marc Autret <autret_m@epita.fr>
17561
17562 * src/bison.simple: Remove #line just before %%epilogue. It
17563 is now handled in ...
17564 * src/reader.c (read_additionnal_code): Add the output of a
17565 #line for the epilogue.
17566
17567 2001-12-10 Marc Autret <autret_m@epita.fr>
17568
17569 * src/reader.c (copy_definition): Re-use CPP-outed code which
17570 replace precedent remove.
17571 * src/bison.simple: Remove #line before %%prologue because
17572 %%input-line is wrong at this time.
17573
17574 2001-12-10 Marc Autret <autret_m@epita.fr>
17575
17576 * src/reader.c (symbols_output): Clean up.
17577 * src/output.c (output_gram, output): Clean up.
17578
17579 2001-12-10 Akim Demaille <akim@epita.fr>
17580
17581 * src/lalr.c (initialize_lookaheads): New. Extracted from...
17582 * src/LR0.c (set_state_table): here.
17583 * src/lalr.c (lalr): Call it.
17584
17585 2001-12-10 Akim Demaille <akim@epita.fr>
17586
17587 * src/state.h (shifts): Remove the `number' member: shifts are
17588 attached to state, hence no longer need to be labelled with a
17589 state number.
17590
17591 2001-12-10 Akim Demaille <akim@epita.fr>
17592
17593 Now that states have a complete set of members, the linked list of
17594 shifts is useless: just fill directly the state's shifts member.
17595
17596 * src/state.h (shifts): Remove the `next' member.
17597 * src/LR0.c (first_state, last_state): Remove.
17598 Adjust the callers.
17599 (augment_automaton): Don't look for the shifts that must be added
17600 a shift on EOF: it is those of the state we looked for! But now,
17601 since shifts are attached, it is no longer needed to looking
17602 merely by its id: its number.
17603
17604 2001-12-10 Akim Demaille <akim@epita.fr>
17605
17606 * src/LR0.c (augment_automaton): Better variable locality.
17607 Remove an impossible branch: if there is a state corresponding to
17608 the start symbol being shifted, then there is shift for the start
17609 symbol from the initial state.
17610
17611 2001-12-10 Akim Demaille <akim@epita.fr>
17612
17613 * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
17614 only when appropriate: when insert_start_shifting_state' is not
17615 invoked.
17616 * tests/regression.at (Rule Line Numbers): Adjust.
17617
17618 2001-12-10 Akim Demaille <akim@epita.fr>
17619
17620 * src/LR0.c (augment_automaton): Now that all states have shifts,
17621 merge the two cases addition shifts to the initial state.
17622
17623 2001-12-10 Akim Demaille <akim@epita.fr>
17624
17625 * src/lalr.c (set_state_table): Move to...
17626 * src/LR0.c: here.
17627 * src/lalr.c (lalr): Don't call it...
17628 * src/LR0.c (generate_states): do it.
17629 * src/LR0.h (first_state): Remove, only the table is used.
17630
17631 2001-12-10 Akim Demaille <akim@epita.fr>
17632
17633 * src/LR0.h (first_shift, first_reduction): Remove.
17634 * src/lalr.c: Don't use first_shift: find shifts through the
17635 states.
17636
17637 2001-12-10 Akim Demaille <akim@epita.fr>
17638
17639 * src/LR0.c: Attach shifts to states as soon as they are
17640 computed.
17641 * src/lalr.c (set_state_table): Instead of assigning shifts to
17642 state, just assert that the mapping was properly done.
17643
17644 2001-12-10 Akim Demaille <akim@epita.fr>
17645
17646 * src/LR0.c (insert_start_shift): Rename as...
17647 (insert_start_shifting_state): this.
17648 (insert_eof_shifting_state, insert_accepting_state): New.
17649 (augment_automaton): Adjust.
17650 Better locality of the variables.
17651 When looking if the start_symbol is shifted from the initial
17652 state, using `while (... symbol != start_symbol ...)' sounds
17653 better than `while (... symbol < start_symbol ...)': If fail
17654 to see how the order between symbols could be relevant!
17655
17656 2001-12-10 Akim Demaille <akim@epita.fr>
17657
17658 * src/getargs.h: Don't declare `spec_name_prefix' and
17659 `spec_file_prefix', declared by src/files.h.
17660 * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
17661 * src/muscle_tab.c (muscle_init): Default prefix to NULL.
17662 * src/output.c (prepare): Adjust.
17663 * src/reader.c (symbols_output): Likewise.
17664 * src/vmsgetargs.c: Vaguely adjust, but who cares?
17665
17666 2001-12-10 Akim Demaille <akim@epita.fr>
17667
17668 * src/muscle_tab.c (muscle_init): NULL is a better default than
17669 `"0"'.
17670
17671 2001-12-10 Akim Demaille <akim@epita.fr>
17672
17673 * src/reader.c (reader): Calling symbols_output once is enough.
17674
17675 2001-12-10 Akim Demaille <akim@epita.fr>
17676
17677 Now that states have a complete set of members, the linked list of
17678 reductions is useless: just fill directly the state's reductions
17679 member.
17680
17681 * src/state.h (struct reductions): Remove member `number' and
17682 `next'.
17683 * src/LR0.c (first_reduction, last_reduction): Remove.
17684 (save_reductions): Don't link the new reductions, store them in
17685 this_state.
17686 * src/lalr.c (set_state_table): No need to attach reductions to
17687 states, it's already done.
17688 * src/output.c (output_actions): No longer free the shifts, then
17689 the reductions, then the states: free all the states and their
17690 members.
17691
17692 2001-12-10 Akim Demaille <akim@epita.fr>
17693
17694 * src/options.c (OPTN, DRTV, BOTH): New.
17695 (option_table): Use them.
17696
17697 * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
17698 the job of system.h.
17699 * src/options.c: Don't include stdio.h and xalloc.h for the same
17700 reasons.
17701
17702 2001-12-10 Akim Demaille <akim@epita.fr>
17703
17704 * src/output.c (output, prepare): Make sure the values of the
17705 muscles `action' and `prologue' are 0-terminated.
17706
17707 2001-12-10 Akim Demaille <akim@epita.fr>
17708
17709 Clean up GCC warnings.
17710
17711 * src/reader.c (copy_action): `buf' is not used.
17712 (parse_skel_decl): Be static.
17713 * src/muscle_tab.c (mhash1, mhash2, muscle_insert): Preserve `const'.
17714 * src/options.h (create_long_option_table): Have a real prototype.
17715 * lib/hash.c, lib/hash.h (hash_insert, hash_insert_at, hash_delete)
17716 (hash_delete_at): Return const void *.
17717 Adjust casts to preserve the const.
17718
17719 2001-12-10 Akim Demaille <akim@epita.fr>
17720
17721 * configure.in: Require 2.52g.
17722 M4 is not needed, but AUTOM4TE is.
17723 * m4/m4.m4: Remove.
17724 * tests/Makefile.am: Adjust.
17725
17726 2001-12-10 Akim Demaille <akim@epita.fr>
17727
17728 One structure for states is enough, even though theoretically
17729 there are LR(0) states and LALR(1) states.
17730
17731 * src/lalr.h (state_t): Remove.
17732 (state_table): Be state_t **, not state_t *.
17733 * src/state.h (core, CORE_ALLOC): Rename as...
17734 (state_t, STATE_ALLOC): this.
17735 Add the LALR(1) members: shifts, reductions, errs.
17736 * src/LR0.c (state_table): Rename as...
17737 (state_hash): this, to avoid name clashes with the global
17738 `state_table'.
17739 * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
17740 * src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.
17741
17742 2001-12-10 Akim Demaille <akim@epita.fr>
17743
17744 Bison dumps core on bash.y.
17745 Reported by Pascal Bart.
17746
17747 * src/warshall.c (bitmatrix_print): New.
17748 (TC): Use it.
17749 When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
17750 j must be the outer loop.
17751 * tests/regression.at (Broken Closure): New.
17752
17753 2001-12-05 Akim Demaille <akim@epita.fr>
17754
17755 * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
17756 its argument.
17757 Reported by Peter Hamorsky.
17758
17759 2001-12-05 Akim Demaille <akim@epita.fr>
17760
17761 * src/conflicts.c (err_table): Remove.
17762 (resolve_sr_conflict): Adjust.
17763 * src/lalr.h (state_t.reduction_table, state_t.shift_table):
17764 Rename as...
17765 (state_t.reductions, state_t.shifts): this.
17766
17767 2001-12-05 Akim Demaille <akim@epita.fr>
17768
17769 * src/reduce.c (reduce_grammar_tables): No longer disable the
17770 removal of useless rules via CPP but via `if (0)', so that the
17771 compiler still check the code is valid.
17772 For instance, it should have noticed `rline' no longer exists: use
17773 the `line' member of rule_t.
17774 * src/gram.c (dummy, rline): Remove, unused.
17775
17776 2001-12-05 Akim Demaille <akim@epita.fr>
17777
17778 * src/output.c (pack_vector): Use assert, not berror.
17779 * src/main.c (berror): Remove, unused.
17780
17781 2001-12-05 Akim Demaille <akim@epita.fr>
17782
17783 New experimental feature: if --verbose --trace output all the
17784 items of a state, not only its kernel.
17785
17786 * src/print.c (print_core): If `trace_flag', then invoke closure
17787 before outputting the items of the state (print_core is no longer
17788 a correct name them).
17789 (print_results): Invoke new_closure/free_closure if needed.
17790
17791 2001-12-05 Akim Demaille <akim@epita.fr>
17792
17793 * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
17794 * src/closure.c, src/closure.h (itemsetsize): Rename as...
17795 (nitemset): for consistency with the rest of the project.
17796
17797 2001-12-05 Akim Demaille <akim@epita.fr>
17798
17799 * src/closure.c (print_closure): Improve.
17800 (closure): Use it for printing input and output.
17801
17802 2001-12-05 Akim Demaille <akim@epita.fr>
17803
17804 * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
17805 indexed by nonterminals.
17806
17807 2001-12-05 Akim Demaille <akim@epita.fr>
17808
17809 * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
17810 what it was!).
17811 * src/warshall.h: Remove accidental duplication of the content.
17812
17813 2001-12-05 Akim Demaille <akim@epita.fr>
17814
17815 * src/closure.c (set_fderives): De-obfuscate.
17816
17817 2001-12-05 Akim Demaille <akim@epita.fr>
17818
17819 * src/closure.c (print_firsts, print_fderives): De-obfuscate.
17820
17821 2001-12-05 Akim Demaille <akim@epita.fr>
17822
17823 * src/closure.c (set_firsts): De-obfuscate.
17824
17825 2001-12-05 Akim Demaille <akim@epita.fr>
17826
17827 * src/output.c (action_row): De-obfuscate
17828 using the good o' techniques: arrays not pointers, variable
17829 locality, BITISSET, RESETBIT etc.
17830
17831 2001-12-05 Akim Demaille <akim@epita.fr>
17832
17833 Pessimize the code to simplify it: from now on, all the states
17834 have a valid SHIFTS, which NSHIFTS is possibly 0.
17835
17836 * src/LR0.c (shifts_new): Be global and move to..
17837 * src/state.c, src/state.h: here.
17838 * src/conflicts, src/lalr.c, src/output.c, src/print.c,
17839 * src/print_graph: Adjust.
17840
17841 2001-12-05 Akim Demaille <akim@epita.fr>
17842
17843 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
17844 * src/conflicts.c: Use it.
17845 Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
17846 incorrectly ``simplified''.
17847
17848 2001-12-05 Akim Demaille <akim@epita.fr>
17849
17850 * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
17851 using the good o' techniques: arrays not pointers, variable
17852 locality, BITISSET, RESETBIT etc.
17853
17854 2001-12-05 Akim Demaille <akim@epita.fr>
17855
17856 * src/state.h (SHIFT_SYMBOL): New.
17857 * src/conflicts.c: Use it to deobfuscate.
17858
17859 2001-12-05 Akim Demaille <akim@epita.fr>
17860
17861 * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
17862 (print_reductions): De-obfuscate using the good o' techniques:
17863 arrays not pointers, variable locality, BITISSET.
17864
17865 2001-12-05 Akim Demaille <akim@epita.fr>
17866
17867 * src/conflicts.c (print_reductions): Arrays, not pointers.
17868 Use BITISSET.
17869
17870 2001-12-05 Akim Demaille <akim@epita.fr>
17871
17872 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17873
17874 2001-12-05 Akim Demaille <akim@epita.fr>
17875
17876 * src/conflicts.c (print_reductions): Improve variable locality.
17877
17878 2001-12-05 Akim Demaille <akim@epita.fr>
17879
17880 * src/conflicts.c (print_reductions): Pessimize, but clarify.
17881
17882 2001-12-05 Akim Demaille <akim@epita.fr>
17883
17884 * src/conflicts.c (print_reductions): Improve variable locality.
17885
17886 2001-12-05 Akim Demaille <akim@epita.fr>
17887
17888 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
17889 * src/lalr.c: Use them.
17890
17891 2001-12-05 Akim Demaille <akim@epita.fr>
17892
17893 * src/LR0.c (augment_automaton): Formatting changes.
17894 Better variable locality.
17895
17896 2001-12-05 Akim Demaille <akim@epita.fr>
17897
17898 * src/lalr.c (matrix_print): New.
17899 (transpose): Use it.
17900 Use arrays instead of pointers.
17901
17902 2001-12-05 Akim Demaille <akim@epita.fr>
17903
17904 * src/lalr.c (maxrhs): Move to...
17905 * src/gram.c, src/gram.h (ritem_longest_rhs): here.
17906 * src/lalr.c (build_relations): Adjust.
17907
17908 2001-12-05 Akim Demaille <akim@epita.fr>
17909
17910 * src/lalr.c (transpose): Free the memory allocated to the
17911 argument, as it is replaced by the results by the unique caller.
17912 (build_relations): Merely invoke transpose: it handles the memory
17913 deallocation.
17914 Improve variable locality.
17915 Avoid variables used as mere abbreviations.
17916 (compute_lookaheads): Use arrays instead of pointers.
17917
17918 2001-12-05 Akim Demaille <akim@epita.fr>
17919
17920 * src/lalr.c (initialize_F): Improve variable locality.
17921 Avoid variables used as mere abbreviations.
17922
17923 2001-12-05 Akim Demaille <akim@epita.fr>
17924
17925 * src/derives.c (print_derives): Display the ruleno.
17926 * src/lalr.c (initialize_F, transpose): Better variable locality
17927 to improve readability.
17928 Avoid variables used as mere abbreviations.
17929
17930 2001-12-05 Akim Demaille <akim@epita.fr>
17931
17932 * src/lalr.c (traverse): Use arrays instead of pointers.
17933
17934 2001-12-05 Akim Demaille <akim@epita.fr>
17935
17936 * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
17937 the handling of squeue.
17938 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17939
17940 2001-12-05 Akim Demaille <akim@epita.fr>
17941
17942 Because useless nonterminals are now kept alive (instead of being
17943 `destroyed'), we now sometimes examine them, and store information
17944 related to them. Hence we need to know their number, and adjust
17945 memory allocations.
17946
17947 * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
17948 static.
17949 * src/LR0.c (allocate_itemsets): The memory allocated to
17950 `symbol_count' was used for two different purpose: once to count
17951 the number of occurrences of each symbol, and later reassigned to
17952 `shift_symbol', containing the symbol that can be shifted from a
17953 given state.
17954 Deobfuscate, i.e., allocate, use and free `symbol_count' here
17955 only, and...
17956 (new_itemsets): Allocate `shift_symbol' here.
17957 (allocate_itemsets): symbol_count includes useless nonterminals.
17958 Make room for them.
17959 (free_storage): Use `free', not `XFREE', for pointers that cannot
17960 be null.
17961
17962 2001-12-05 Akim Demaille <akim@epita.fr>
17963
17964 * src/nullable.c (set_nullable): Deobfuscate the handling of
17965 ritem.
17966 `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.
17967
17968 2001-12-05 Akim Demaille <akim@epita.fr>
17969
17970 * src/gram.c, src/gram.h (ritem_print): New.
17971 * src/gram.c (dummy): Remove, now there is actual code in gram.c.
17972 (This useless function was defined only to work around VMS linkers
17973 that can't handle compilation units with variables only).
17974 * src/reduce.c (dump_grammar): Use it to trace the construction of
17975 ritem.
17976
17977 2001-12-04 Paul Eggert <eggert@twinsun.com>
17978
17979 * src/bison.simple (union yyalloc): Change member names
17980 to be the same as the stack names.
17981 (yyparse): yyptr is now union yyalloc *, not char *.
17982 (YYSTACK_RELOCATE): Likewise. This avoids a GCC warning,
17983 and may generate better code on some machines.
17984 (yystpcpy): Use prototype if __STDC__ is defined, not just
17985 if __cplusplus is defined.
17986
17987 2001-11-30 Akim Demaille <akim@epita.fr>
17988
17989 * configure.in (WARNING_CFLAGS): Add -Werror when possible.
17990 (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
17991 Gettext doesn't compile cleanly, and dies with -Werror.
17992 * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
17993 Include WARNING_CFLAGS here.
17994 * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
17995 before being defined.
17996
17997 2001-11-27 Paul Eggert <eggert@twinsun.com>
17998
17999 * lib/quotearg.h (quotearg_n, quotearg_n_style):
18000 First arg is int, not unsigned.
18001 * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
18002 (SIZE_MAX, UINT_MAX): New macros.
18003 (quotearg_n_options): Abort if N is negative.
18004 Avoid overflow check on hosts where size_t is 64 bits and int
18005 is 32 bits, as overflow is impossible there.
18006 Fix off-by-one typo that caused unnecessary reallocation.
18007
18008 2001-11-29 Paul Eggert <eggert@twinsun.com>
18009
18010 Name space cleanup in generated parser.
18011
18012 * doc/bison.texinfo (Bison Parser): Discuss system headers
18013 and their effect on the user name space.
18014
18015 * src/bison.simple:
18016 (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
18017 YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
18018 i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).
18019
18020 (YYSIZE_T): New macro. Use it instead of size_t, to avoid infringing
18021 on user names when possible.
18022
18023 (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
18024 Simplify test for whather <alloca.h> exists.
18025
18026 (<stdlib.h>): Include if we will use malloc, and if standard C or C++.
18027
18028 (<stdio.h>): Include if YYDEBUG.
18029
18030 (yymemcpy): Renamed from __yy_memcpy. Do not define unless
18031 ! defined (yyoverflow) && ! defined (yymemcpy).
18032
18033 (yymemcpy, yyparse): Rename local variables as needed so that
18034 they all begin with 'yy'.
18035
18036 (yystrlen, yystpcpy): New functions.
18037
18038 (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
18039 All uses changed.
18040
18041 (yyparse): size_t -> YYSIZE_T. Use yystrlen and yystpcpy
18042 instead of relying on string.h functions. Use YYSTACK_ALLOC
18043 and YYSTACK_FREE instead of malloc and free.
18044
18045 2001-11-30 Akim Demaille <akim@epita.fr>
18046
18047 * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
18048 before their first uses.
18049 (YYBISON, YYPURE): Move to the top of the output.
18050
18051 2001-11-30 Akim Demaille <akim@epita.fr>
18052
18053 * tests/reduce.at (Useless Nonterminals): Fix.
18054
18055 2001-11-30 Akim Demaille <akim@epita.fr>
18056
18057 * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
18058 if body instead of `;' to pacify GCC's warnings.
18059
18060 2001-11-30 Akim Demaille <akim@epita.fr>
18061
18062 Instead of mapping the LHS of unused rules to -1, keep the LHS
18063 valid, but flag the rules as invalid.
18064
18065 * src/gram.h (rule_t): `useful' is a new member.
18066 * src/print.c (print_grammar): Adjust.
18067 * src/derives.c (set_derives): Likewise.
18068 * src/reader.c (packgram, reduce_output): Likewise.
18069 * src/reduce.c (reduce_grammar_tables): Likewise.
18070 * tests/reduce.at (Underivable Rules, Useless Rules): New.
18071
18072 2001-11-30 Akim Demaille <akim@epita.fr>

18101 an arbitrary restriction on hosts where size_t is wider than int.
18102
18103 (yyparse): Don't dump core if alloca or malloc fails; instead, report
18104 a parser stack overflow. Allocate just one block of memory for all
18105 three stacks, instead of allocating three blocks; this typically is
18106 faster and reduces fragmentation.
18107
18108 Do not limit the number of items in the stack to a value that fits
18109 in 'int', as this is an arbitrary limit on hosts with 64-bit
18110 size_t and 32-bit int.

18536
18537 * tests/calc.at, tests/output.at, tests/regression.at,
18538 * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:
18539 now the tests are run in private dirs, therefore AC_CLEANUP and
18540 family can be simplified to 0-ary.
18541 * tests/atlocal.in: Now that we run `elsewhere' than in tests/,
18542 use abs. path to find config.h.
18543 * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

18549

18561
18562 * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
18563 Revert a previous patch: these are really const.

18565 braces to pacify GCC's warnings for `if () if () {} else {}'.
18566 * src/lex.c (parse_percent_token): Replace equal_offset with
18567 arg_offset.
18568 arg is const.
18569 Be sure to strdup `arg' when used, since there is no reason for
18570 token_buffer not to change.

19914

19922 New, from fileutils 4.0.37.
19923 * configure.in: Require Autoconf 2.49c. I took some time before
19924 making this decision. This is the only way out for portability
19925 issues in Bison, it would mean way too much duplicate effort to
19926 import in Bison features implemented in 2.49c since 2.13.
19927 AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.

19943
19944 2001-01-19 Akim Demaille <akim@epita.fr>
19945
19946 * src/lex.h: Rename all the tokens:
19947 s/\bENDFILE\b/tok_eof/g;
19948 s/\bIDENTIFIER\b/tok_identifier/g;
19949 etc.
19950 Let them be enums, not #define, to ease debugging.
19951 Adjust all the code.
19952
19953 2001-01-18 Akim Demaille <akim@epita.fr>

19961
19962 * src/lex.c (percent_table): Also accept `%yacc',
19963 `%fixed_output_files', `%defines', `%no_parser', `%verbose', and

19966 instead of returning a token.
19967 * src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
19968 * src/reader.c (read_declarations): Adjust.
19969 * src/files.c (open_files): Don't call `compute_base_names', don't
19970 compute `attrsfile' since they depend upon data which might be
19971 *in* the input file now.
19972 (output_files): Do it here.
19973 * src/output.c (output_headers): Document the fact that this patch
19974 introduces a guaranteed SEGV for semantic parsers.

19996
19997 * src/reader.c (copy_string, copy_comment, copy_comment2, copy_at)

19999 FILE * parameters.
20000
20001 2000-12-20 Akim Demaille <akim@epita.fr>
20002
20003 * src/files.c (open_files): Actually the `.output' file is based

20033 (stringappend): Be just like strcat but allocate.

20038 * tests/suite.at (Checking output file names): New test.
20039

20076 2000-12-19 Akim Demaille <akim@epita.fr>
20077
20078 * src/files.c (open_files): Yipee! We no longer need all the code
20079 looking for `/tmp' since we have no tmp file.
20080
20081 2000-12-19 Akim Demaille <akim@epita.fr>

20112 prevents type checking.

20163 Qualify it `const'.
20164 (obstack_copy, obstack_copy0): Rename the second argument as

20270
20271 * src/reader.c (copy_comment2): Expect the input stream to be on
20272 the `/' which is suspected to open a comment, instead of being
20273 called after `//' or `/*' was read.
20274 (copy_comment, copy_definition, parse_union_decl, copy_action)
20275 (copy_guard): Adjust.
20276
20277 2000-10-16 Akim Demaille <akim@epita.fr>

20302
20303 2000-10-04 Akim Demaille <akim@epita.fr>
20304
20305 When a literal string is used to define two different tokens,
20306 `bison -v' segfaults.
20307 Reported by Piotr Gackiewicz, and fixed by Neil Booth.
20308

20318 From Neil Booth.
20319
20320 2000-10-02 Paul Eggert <eggert@twinsun.com>
20321
20322 * bison.s1 (yyparse): Assign the default value
20323 unconditionally, to avoid a GCC warning and make the parser a
20324 tad smaller.
20325
20326 2000-10-02 Akim Demaille <akim@epita.fr>
20327
20328 * src/getargs.c (getargs): Don't dump `--help' on unrecognized
20329 options.
20330
20331 2000-10-02 Akim Demaille <akim@epita.fr>
20332
20333 * src/derives.c, src/print.c, src/reduce.c: To ease the
20334 translation, move some `\n' out of the translated strings.
20335
20336 2000-10-02 Akim Demaille <akim@epita.fr>
20337
20338 The location tracking mechanism is precious for parse error
20339 messages. Nevertheless, it is enabled only when `@n' is used in
20340 the grammar, which is a different issue (you can use it in error
20341 message, but not in the grammar per se). Therefore, there should
20342 be another means to enable it.
20343
20344 * src/getargs.c (getargs): Support `--locations'.
20345 (usage): Report it.
20346 * src/getargs.h (locationsflag): Export it.
20347 * src/lex.c (percent_table): Support `%locations'.
20348 * src/reader.c (yylsp_needed): Remove this variable, now replaced
20349 with `locationsflag'.
20350 * doc/bison.texinfo: Document `--locations' and `%locations'.
20351 Sort the options.
20352 * tests/calc.m4: Test it.
20353
20354 For regularity of the names, replace each
20355 (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
20356 (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
20357 In addition replace each `flag' with `_flag'.
20358
20359 2000-10-02 Akim Demaille <akim@epita.fr>
20360
20361 Also test parse error messages, including with YYERROR_VERBOSE.
20362
20363 * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
20364 associative).
20365 Use it to check the computations.
20366 Use it to check `nonassoc' is honored.
20367 (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
20368 `--yyerror-verbose'.
20369 (_AT_CHECK_CALC): Adjust to this option.
20370 (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
20371
20372 2000-10-02 Akim Demaille <akim@epita.fr>
20373
20374 Test also `--verbose', `--defines' and `--name-prefix'. Testing
20375 the latter demonstrates a flaw in the handling of non debugging
20376 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
20377 was used in order to simplify:
20378
20379 #if YYDEBUG
20380 if (yydebug)
20381 {
20382 ...
20383 }
20384 #endif
20385
20386 into
20387
20388 if (yydebug)
20389 {
20390 ...
20391 }
20392
20393 unfortunately this leads to a CPP conflict when
20394 `--name-prefix=foo' is used since it produces `#define yydebug
20395 foodebug'.
20396
20397 * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
20398 (YYDPRINTF): New macro.
20399 Spread its use.
20400 * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
20401 the bison options.
20402 Also test `--verbose', `--defines' and `--name-prefix'.
20403
20404 2000-10-02 Akim Demaille <akim@epita.fr>
20405
20406 Improve the readability of the produced parsers.
20407
20408 * src/bison.s1: Formatting changes.
20409 Improve the comment related to the `$' mark.
20410 (yydefault): Don't fall through to `yyresume': `goto' there.
20411 * src/output.c (output_parser): When the `$' is met, skip the end
20412 of its line.
20413 New variable, `number_of_dollar_signs', to check there's exactly
20414 one `$' in the parser skeleton.
20415
20416 2000-10-02 Akim Demaille <akim@epita.fr>
20417
20418 * lib/xstrdup.c: New file, from the fileutils.
20419 * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
20420 (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
20421 instead of strlen + xmalloc + strcpy.
20422 * src/symtab.c (copys): Remove, use xstrdup instead.
20423
20424 2000-10-02 Akim Demaille <akim@epita.fr>
20425
20426 * src/gram.h (associativity): New enum type which replaces the
20427 former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
20428 `right_assoc', `left_assoc' and `non_assoc'.
20429 Adjust all dependencies.
20430 * src/reader.c: Formatting changes.
20431 (LTYPESTR): Don't define it, use it as a literal in
20432 `reader_output_yylsp'.
20433 * src/symtab.h (symbol_class): New enum type which replaces the
20434 former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
20435 `sunknown', `stoken and `snterm'.
20436
20437 2000-10-02 Akim Demaille <akim@epita.fr>
20438
20439 * src/getargs.c (fixed_outfiles): Rename as...
20440 (yaccflag): for consistency and accuracy.
20441 Adjust dependencies.
20442
20443 2000-10-02 Akim Demaille <akim@epita.fr>
20444
20445 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
20446 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
20447 difficult and introduced a lot of core dump. It turns out that
20448 Bison used an implementation of `xmalloc' based on `calloc', and
20449 at various places it does depend upon the initialization to 0. I
20450 have not tried to isolate the pertinent places, and all the former
20451 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
20452 someone should address this issue.
20453
20454 * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
20455 * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New

20499 * src/conflicts.h: New file.
20500 Propagate its inclusion.
20501
20502 2000-10-02 Akim Demaille <akim@epita.fr>

20531 s/register//.
20532
20533 2000-10-02 Akim Demaille <akim@epita.fr>
20534

20550 YYDEFACT, that makes it possible for this function to use
20551 output_short_table.
20552
20553 2000-10-02 Akim Demaille <akim@epita.fr>
20554
20555 `user_toknums' is output as a `short[]' in `output.c', while it is
20556 defined as a `int[]' in `reader.c'. For consistency with the
20557 other output tables, `user_toknums' is now defined as a table of
20558 shorts.
20559
20560 * src/reader.c (user_toknums): Be a short table instead of an int
20561 table.
20562 Adjust dependencies.

20599 inclusion.
20600 Don't define PARAMS.
20601 * src/system.h: Define PARAMS.
20602 Remove some of the ad-hoc CPP magic for DOS, VMS etc.: this is the
20603 purpose of config.h. system.h must not try to fix wrong
20604 definitions in config.h.
20605
20606 2000-09-20 Akim Demaille <akim@epita.fr>

20633 * tests/calc.m4 (yyin): Be initialized in main, not on the global
20634 scope.

20822 Change the handling of @s so that they behave exactly like $s.
20823 There is now a pseudo variable @$ (readble and writable), location
20824 of the lhs of the rule (by default ranging from the location of
20825 the first symbol of the rhs, to the location of the last symbol,

20861 remove most `#if YYDEBUG != 0', since `if (yydebug)' is enough.

21589 way to specify the flags -n, -l, and -r. Also added hooks for
