59 global: remove unnecessary horizontal tabs.
60 This change was made by applying emacs' untabify function to
61 nearly all files in Bison's repository. Required tabs in make
62 files, ChangeLog, regexps, and test code were manually skipped.
63 Other notable exceptions and changes are listed below.
64 * bootstrap: Skip because we sync this with gnulib.
65 * data/m4sugar/foreach.m4
66 * data/m4sugar/m4sugar.m4: Skip because we sync these with
67 Autoconf.
68 * djgpp: Skip because I don't know how to test djgpp properly, and
69 this code appears to be unmaintained anyway.
70 * README-hacking (Hacking): Specify that tabs should be avoided
71 where not required.

155 Don't use IF_LINT in Bison sources.
156 It creates unnecessary differences between the sources that Bison
157 maintainers build and test (given that maintainers normally
158 configure with --enable-gcc-warnings) and the sources that Bison
159 users build. Instead, use PACIFY_CC, which doesn't. This change
160 fixes compiler warnings reported by Tys Lefering at
161 <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
162 * configure.ac: Don't AC_DEFINE lint regardless of the configure
163 options. This change affects imported gnulib sources, where
164 IF_LINT still appears and depends on lint.
165 * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
166 PACIFY_CC.

173 Since Bison 2.3b, which restored the ability of precedence
174 directives to assign user token numbers, doing so for user token
175 number 0 has produced an assertion failure.
176 * NEWS (2.5): Document fix.
177 * src/symtab.c (symbol_user_token_number_set): In the case of the
178 end token, don't decrement ntokens if it was never incremented.

194 strchr and strrchr. In the cases of command-line options, file
195 names, and thus locations, functionality may be improved. In the
196 case of symbol names, there should be no functional difference as
197 all characters are ASCII, so the intended benefit is just warning
198 suppression.

546 doc: clean up naming of various Bison files.
547 The Bison manual's names for various files associated with a Bison
548 parser has devolved into inconsistency. This patch makes the
549 naming consistent for the most important files. First, it chooses
550 "grammar file" over "input file". The former appears to be more
551 traditional in the Bison manual, and Bison has other input
552 files (skeletons). Second, it chooses "parser implementation
553 file" over names like "parser file", "parser source file", "parser
554 source code file", and "parser output file". The new name makes
555 it clearer where Bison generates the main parser implementation,
556 and it is easily distinguishable from "parser header file".

583 Do not allow identifiers that start with a dash.
584 This cleans up our previous fixes for a bug whereby Bison
585 discarded `.field' in `$-1.field'. The previous fixes were less
586 restrictive about where a dash could appear in an identifier, but
587 the restrictions were hard to explain. That bug was reported and
588 this final fix was originally suggested by Paul Hilfinger. This
589 also fixes a remaining bug reported by Paul Eggert whereby Bison
590 parses `%token ID -123' as `%token ID - 123' and handles `-' as an
591 identifier. Now, `-' cannot be an identifier. Discussed in
592 threads beginning at

630 Improve error messages for `$' or `@' followed by `.' or `-'.
631 Previously, for this special case of an invalid reference, the
632 usual "symbol not found in production:" was printed. However,
633 because the symbol name was parsed as the empty string, that
634 message was followed immediately by a newline instead of a symbol
635 name. In reality, this is a syntax error, so the reference is
636 invalid regardless of the symbols actually appearing in the
637 production. Discussed at

766 However, one point there must be corrected: because of %nonassoc,
767 LAC is *not* always redundant for lr.type=canonical-lr.
768 * data/yacc.c: Accept values of "none" (default) or "full" for

777 (yy_lac): New function that, given the current stack, determines
778 whether a token can eventually be shifted. Return status mimics
779 yyparse return status.
780 (yysyntax_error): Change yystate argument to yyssp so stack top
781 can be passed to yy_lac. If LAC is requested, build expected
782 token list by invoking yy_lac for every token instead of just
783 checking the current state for lookaheads. Return 2 if yy_lac
784 exhausts memory.

786 cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
787 Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
788 is requested.

815 drop the unexpected token unless there actually is no lookahead.
816 Moreover, handle that internally instead of returning 1 to tell

854 yysyntax_error: prepare for readability of next patches.
855 These are purely whitespace changes that result in ugly code
856 but that make the next couple of patches much easier to read.
857 * data/glr.c (yyreportSyntaxError): Reindent.

871 invocation, get rid of the while loop, which is misleading

900 Adjust to recent changes to gnulib bootstrap.

902 * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
903 * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
904 * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
905 * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
906 anymore and don't know of anybody else who does. If someone needs
907 these files, they can resurrect them.
908 * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
909 * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
910 Omit leading '/', since bootstrap omits it.
911 Adjust file names to match current contents better.
912 * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
913 installed just for us.
914 * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
915 glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
916 needed somehow. Don't have time to look into why.
917 (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
918 the GNU malloc behavior, where malloc (0) != NULL unless we're
919 out of storage? If not, we can omit malloc-gnu; but for now I left
920 it in to be safe.
921 (vc_ignore): Remove.
922 (gnulib_mk_hook): New function.
923 * README-hacking: Renamed from HACKING, since gnulib bootstrap now
924 uses that convention.

1433 portability: fix several issues with M4 subprocess.
1434
1435 M4's output pipe was not being drained upon fatal errors during
1436 scan_skel. As a result, broken-pipe messages from M4 were seen
1437 on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
1438 failure in the test suite. The problem was that, on platforms
1439 where the default disposition for SIGPIPE is ignore instead of
1440 terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
1441 then reported it. However, there's some sort of race condition,
1442 because the new test group occasionally succeeded.

1617 Fix handling of yychar manipulation in user semantic actions.
1618 The problem was that yacc.c didn't always update the yychar
1619 translation afterwards. However, other skeletons appear to be
1620 fine. glr.c appears to already translate yychar before every
1621 use. lalr1.cc does not define yychar and does not document its
1622 replacement, yyla, for users. It does provide yyclearin, but
1623 that does not manipulate yyla and thus requires no translation
1624 update. In lalr1.java, yychar is out of scope during semantic
1625 actions.

1639 the destructor call is fixed by this patch, the verbose error
1640 message is currently incorrect due to another bug (see

1834 yysyntax_error: avoid duplicate lookahead collection.
1835 Except when memory reallocation is required, this change
1836 eliminates the need to invoke yysyntax_error twice and thus to
1837 repeat the collection of lookaheads. It also prepares for
1838 future extensions that will make those repetitions more
1839 expensive and that will require additional memory management in
1840 yysyntax_error. Finally, it fixes an obscure bug already
1841 exercised in the test suite.

2224 (yygetLRActions): Check for default value from yypact. It
2225 appears that this check is always performed before this function
2226 is invoked, and so adding the check here is probably redundant.
2227 However, the code may evolve after this subtlety is forgotten.
2228 Also, update for rename to yytable_value_is_error. Because that

2460 build: fix the generation of the documentation.
2461 Some of our targets use "bison --help", but they can't depend on
2462 "bison" itself (to avoid additional requirements on the user), so
2463 they used to call "make src/bison" in the commands. Then
2464 concurrent builds may fail: one make might be aiming one of its
2465 jobs at compiling src/bison, and another job at generating the man
2466 page. If the latter is faster than the former, then we have two
2467 makes that concurrently try to compile src/bison.

2501 build: fix paths.
2502 When using $(top_builddir) inconsistently, Make (including GNU
2503 Make) is sometimes confused. As a result it may want to build
2504 lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
2505 file, different names) concurrently, which, amusingly enough,
2506 might end with:
2507

4257
4258 There are two issues to handle: first scanning nested angle
4259 bracket pairs to support types such as std::pair< std::string,
4260 std::list<std::string> > >.
4261
4262 Another issue is to address idiosyncracies of C++: do not glue two
4263 closing angle brackets together (otherwise it's operator>>), and
4264 avoid sticking blindly a TYPE to the opening <, as it can result
4265 in '<:' which is a digraph for '['.

4577 Finer input type for yytranslate.
4578 This patch is debatable: the tradition expects yylex to return an int
4579 which happens to correspond to token_number (which is an enum). This
4580 allows for instance to return characters (such as '*' etc.). But this
4581 goes against the stronger typing I am trying to have with the new
4582 lex interface which return a symbol_type. So in this case, feed
4583 yytranslate_ with a token_type.

4760 Introduce make_symbol.
b06df3c2
AD
4761 make_symbol provides a means to construct a full symbol (kind,
4762 value, location) in a single shot. It is meant to be a Symbol
4763 constructor, parameterized by the symbol kind so that overloading
4764 would prevent incorrect kind/value pairs. Unfortunately
4765 parameterized constructors do not work well in C++ (unless the
4766 parameter also appears as an argument, which is not acceptable),
4767 hence the use of a function instead of a constructor.

4982 Change the handling of the symbols in the skeletons.
4983 Before we were using tables which lines were the symbols and which
4984 columns were things like number, tag, type-name etc. It is was
4985 difficult to extend: each time a column was added, all the numbers had
4986 to be updated (you asked for colon $2, not for "tag"). Also, it was
4987 hard to filter these tables when only a subset of the symbols (say the
4988 tokens, or the nterms, or the tokens that have and external number
4989 *and* a type-name) was of interest.

4991 Now instead of monolithic tables, we define one macro per cell. For
4992 instance "b4_symbol(0, tag)" is a macro name which contents is
4993 self-decriptive. The macro "b4_symbol" provides easier access to
4994 these cells.

5317 Unfortunately this uncovered a bug in the C++ parser itself: the
5318 lookahead value was not destroyed between two calls to yylex. For
5319 instance if the previous lookahead was a std::string, and then an int,
5320 then the value of the std::string was correctly taken (i.e., the
5321 lookahead was now an empty string), but std::string structure itself
5322 was not reclaimed.
de62edee 5323
2d32fc9f
AD
5324 This is now done in variant::build(other&) (which is used to take the
5325 value of the lookahead): other is not only stolen from its value, it
5326 is also destroyed. This incurs a new performance penalty of a few
5327 percent, and union becomes faster again.

5608 Fuse the three stacks into a single one.
de62edee 5609
b06df3c2
AD
5610 In order to make it easy to perform benchmarks to ensure that
5611 there are no performance loss, lalr1.cc is forked into
5612 lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
5613 lalr1.cc.
5614
5615 Meanwhile, to make sure that lalr1-fusion.cc is correctly
5616 exercized by the test suite, the user must install a symbolic link
5617 from lalr1.cc to it.

5619 Instead of having three stacks (state, value, location), use a
5620 stack of triples. This considerably simplifies the code (and it
5621 will be easier not to require locations as currently does the C++
5622 parser), and also gives a 10% speedup according to
5623 etc/bench (probably mainly since memory allocation is done once
5624 instead of three times).
de62edee 5625
0e0ed236

5626 Another motivation is to make it easier to destruct properly
5627 semantic values: now that they are bound to their state (hence
5628 symbol type) it will be easier to call the appropriate destructor.

5675 Use variants to support objects as semantic values.
b06df3c2
AD
5676 This patch was inspired by work by Michiel De Wilde. But he used
5677 Boost variants which (i) requires Boost on the user side, (ii) is
5678 slow, and (iii) has useless overhead (the parser knows the type of
5679 the semantic value there is no reason to duplicate this
5680 information as Boost.Variants do).
5681
5682 This implementation reserves a buffer large enough to store the
5683 largest objects. yy::variant implements this buffer. It was
5684 implemented with Quentin Hocquet.

6239 Update to the current gnulib CVS repository, and fix trigraph handling
6240 in Bison.
6241 * bootstrap: Update gnulib CVS repository URL.
6242 (symlink_to_dir): Encapsulate the code that guarantees the destination
6243 directory exists into...
6244 (check_dst_dir): ... this new function, and...
6245 (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't
6246 fail when copying files into lib/uniwidth/.
6247 * src/output.c (prepare_symbols): When writing yytname muscles, where
6248 symbol names will be encoded in C-string literals, tell quotearg to
6249 escape trigraphs. This used to be the default in gnulib.
6250 * tests/regression.at (Token definitions): Because of the change in
6251 gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
6252 escapes trigraphs in symbol names. Thus, yytname no longer has
6253 trigraphs unnecessarily doubly escaped. Update test case output.
6254 Extend test case to be sure Bison's own error messages will no longer
6255 have trigraphs in symbol names unnecessarily escaped once.

7387 The original form of this check appeared in revision 1.1 of lalr.c,

7389 consistency label on such a state appears to have no useful effect in
7390 any of the places it is examined, which I enumerate below. The key
7391 point to understanding each item in this enumeration is that a state
7392 with an error transition is labelled consistent in the first place only
7393 if it has no rules, so the check cannot matter for states that have
7394 rules. (1) Labelling a state as inconsistent will cause set_conflicts
7395 to try to identify its conflicts, and a state must have *rules* to have
7396 conflicts. (2) Labelling a state as inconsistent will affect how
7397 action_row sets the default *rule* for the state. (3) Labelling a
7398 state as inconsistent will cause build_relations to add lookback edges
7399 to *rules* in that state.
7400 * src/state.h (struct state): Word the comment for member consistent
7401 more carefully.

7900 Clean up %define and %code implementation in M4 some. Most
7901 importantly, rename all related macros to be in the b4_percent_define
7902 and b4_percent_code namespaces. Also, complete support for `.' in
7903 %define variable names and %code qualifiers.
7904 * data/bison.m4 (b4_check_user_names): Check for special
7905 "SKELETON-NAMESPACE(name)" macros instead of using two nested
7906 m4_foreach loops.
7907 (b4_get_percent_define, b4_get_percent_code): Rename to...
7908 (b4_percent_define_get, b4_percent_code_get): ... these.
7909 Extend documentation with examples.
7910 For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
7911 b4_percent_define_skeleton_variables and
7912 b4_percent_code_skeleton_qualifiers.
7913 Expect any value for the %define variable `foo' to be stored in the
7914 macro named `b4_percent_define(foo)'; expect any %code blocks for the
7915 qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
7916 expect any unqualified %code blocks to be stored in a macro named
7917 `b4_percent_code_unqualified'.
7918 Use m4_indir so that %define variable names and %code qualifiers can
7919 contain `.', which is allowed by the grammar parser.
7920 (b4_percent_define_default): New macro to set a default value for a
7921 %define variable.
7922 (m4_wrap): Update wrapped code, and fix some underquoting.
7923 (b4_check_user_names_wrap): Update and define outside the m4_wrap.
7924 Expect grammar uses of %define variables and %code qualifiers to be
7925 defined in b4_percent_define_user_variables and
7926 b4_percent_code_user_qualifiers.
7927 * data/c++.m4: Use b4_percent_define_default rather than
7928 m4_define_default. Fix some underquoting. Skeleton usage of %define
7929 variable define_location_comparison now implies skeleton usage of

8039 Instead of having skeletons declare all valid %define variables and

8042 variable or qualifier is not used by the skeleton in the current
8043 invocation regardless of whether it might sometimes be used by that
8044 skeleton in other invocations. Also, move all %define value macros to
8045 the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
8046 form, which is replaced by %code.
8047 * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...

8051 Warn instead of complaining.
8052 (b4_get_percent_define, b4_get_percent_code): New to retrieve %define

8183 skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
8184 directives. Because these M4 macros might be called when the current
8185 diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
8186 the previous removal of uses of m4_divert, which caused trouble.
8187 (b4_check_percent_code_qualifiers): Use b4_complain instead of

8353 code_props with no code.
8354 (code_props_plain_init, code_props_symbol_action_init,
8355 code_props_rule_action_init, code_props_translate_code): The rest of
8356 the new code_props functional interface. Among other things, the init
8357 functions set the code_props kind field so that
8358 code_props_translate_code will know whether to behave like
8359 translate_symbol_action, translate_rule_action, or translate_code.

8371 (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
8372 code_props since Bison may one day use this information for destructors
8373 and printers.
8374 (<*><<EOF>>): Use STRING_FINISH so that last_string is set.

8563 Rearrange initialization of the parser state variables so that the
8564 skeleton doesn't have to have a copy for pull mode and another for push
8565 mode. This patch also fixes at least a bug such that yylloc was not
8566 initialized (with b4_location_initial_line and
8567 b4_location_initial_column) upon calling yypush_parse. However, that
8568 initialization now overwrites the first token's location;
8569 %initial-action assigning @$ already did the same thing, and both bugs

8580 "Starting parse" diagnostic for invocations after the first.
8581 Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
8582 yypush_parse, only do it for the first invocation.

9674 Whether the default %destructor/%printer applies to a particular symbol
9675 isn't a question of whether the user *declares* that symbol (in %token,
9676 for example). It's a question of whether the user by any means
9677 *defines* the symbol at all (by simply using a char token, for
9678 example). $end is defined by Bison whereas any other token with token
9679 number 0 is defined by the user. The error token is always defined by
9680 Bison regardless of whether the user declares it with %token, but we
9681 may one day let the user define error as a nonterminal instead.
9682 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
9683 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document

10069 (yy_stack_print): Don't assume that yytype_int16 promotes to int;
10070 this was never guaranteed, and now that we're using gnulib stdint,
10071 which defines int_fast16_t to long int, the problem is exposed.

10079 Adjust to Autoconf 2.60 and today's gnulib.
10080 * bootstrap (gnulib_modules): Add stdint.
10081 Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
10082 no longer copies it.
10083 (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
10084 since stdint needs the former and wcwidth (which is now required
10085 by mbswidth) needs the latter.
10086 Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
10087 work around a compatibility glitch between gettext 0.14.6 and
10088 Autoconf 2.60.
10089 * configure.ac (AC_PREREQ): Require Autoconf 2.60.
10090 Do not check for uintptr_t, since new stdint module does the right
10091 thing.

10103 (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
10104 Define unconditionally, since we now assume the stdint module.
10105 * src/scan-skel.l: Include <dirname.h>.
10106 (BASE_QPUTS): Use last_component, not base_name.
10107 * src/system.h: Include <unlocked-io.h> in the usual order
10108 for ../lib/*.h files. Include <stdint.h> unconditionally,
10109 since we now use the stdint module.
10110 (uintptr_t): Declare if UINTPTR_MAX is not defined, not
10111 HAVE_UINTPTR_T, since we now use the stdint module.
10112 (base_name): Remove decl, since files now include <dirname.h>
10113 to get the decl.

10194 Don't record whether the midrule's $$ has been used yet since actions
10195 haven't been translated yet.
10196 Record the midrule's parent rule and its RHS index within the parent
10197 rule.
10198 (grammar_current_rule_action_append): Don't translate the action yet
10199 since not all symbol declarations may have been parsed yet and, thus,
10200 warnings about types for $$, $n, @$, and @n can't be reported yet.
10201 (packgram): Translate the action and invoke grammar_rule_check now that
10202 all symbol declarations have been parsed.
10203 * src/scan-code.l (handle_action_dollar): Now that this is invoked
10204 after parsing the entire grammar file, the symbol list here in the case
10205 of a midrule is actually the midrule's empty RHS, so reference its
10206 parent rule's RHS where necessary.
10207 On the other hand, now that you can already know it's a midrule, you
10208 aren't forced to think $$ has the same type as its parent rule's $$.
10209 (handle_action_at): In the case of a midrule, reference the parent rule
10210 where necessary.
10211 * src/symlist.c (symbol_list_new): Initialize new midrule-related
10212 members.
10213 (symbol_list_length): Now that this is invoked after all rules have
10214 been parsed, a NULL symbol (rather than a NULL symbol list node)
10215 terminates a rule. symbol_list_print already does this correctly.
10216 * src/symlist.h (symbol_list.midrule_parent_rule,
10217 symbol_list.midrule_parent_rhs_index): New members so that midrules can
10218 remember their relationships with their parents.
10219 * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
10220 fixed by the above patch.

10225 This one is the same as `Unused values' except that all symbol

10416 to maintainers. I haven't received any responses to my request
10417 for supporting the old way, or for documenting the new way. I
10418 have modified 'bootstrap' to use screen scraping
10419 (in this case, HTML scraping). This is unreliable and inelegant,
10420 but I don't see any better way. Yuck.
10421 * bootstrap (TP_URL, WGET_COMMAND): New vars.
10422 (get_translations): New function, which uses HTML scraping to
10423 deduce locations of latest translations.
10424 Use this function to grab both bison and bison-runtime .po files.
10425 Don't bother priming the pump for the runtime-po domain any more,
10426 as it's now translated better than bison is.

ae952af2 11035 (yyresolveStates): Document the interface. Move all manipulation of a
520181ab
JD
11036 successfully or unsuccessfully resolved yyGLRState to...
11037 (yyresolveValue): ... here so that yyresolveValue always leaves a
11038 yyGLRState with consistent data and thus is easier to understand.
11039 Remove the yyvalp and yylocp parameters since they are always just
11040 taken from the yys parameter. When reporting a discarded merged value
11041 in debugging output, note that it is incompletely merged. Document the
11042 interface.
11043 (yyresolveAction): If resolving any of the RHS states fails, destroy
11044 them all rather than leaking them. Thus, as long as user actions are
11045 written to clean up the RHS correctly, yyresolveAction always cleans up
11046 the RHS of a semantic option. Document the interface.

11165 During deterministic GLR operation, user actions should be able to
11166 influence the parse by changing yychar. To make this easier to fix and
11167 to make glr.c easier to evolve in general, don't maintain yytoken in
11168 parallel with yychar; just compute yytoken when needed.
11169 * tests/glr-regression.at (Incorrect lookahead during deterministic
11170 GLR): Check that setting yychar in a user action has the intended
11171 effect.
11172 * data/glr.c (yyGLRStack): Remove yytokenp member.
11173 (yyclearin): Don't set *yytokenp.
11174 (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine
11175 yychar rather than *yytokenp to determine the current lookahead.
11176 Compute yytoken locally when needed.
11177 (yyparse): Likewise. Remove the local yytoken that yytokenp used to
11178 point to.
11179
11180 * doc/bison.texinfo (Bison Options): Remove stray sentence fragment
11181 after `--report' documentation.

11195 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
11196 got from <http://bro-ids.org/download.html>. The bug is that
11197 when two actions appeared in succession, the second one was
11198 scanned before the first one was added to the grammar rule
11199 as a midrule action. Bison then output the incorrect warning
11200 "parse.y:905.17-906.36: warning: unused value: $3".

11529 * data/glr.c (yyresolveValue): When merging semantic options, if at
11530 least one user action succeeds but a later one cuts the parse, then
11531 destroy the semantic value before returning rather than leaking it.
11532 (yyresolveStates): If a user action cuts the parse and thus
11533 yyresolveValue fails, ignore the (unset) semantic value rather than
11534 corrupting the yyGLRState, and empty the semantic options list since
11535 the user actions should have called all necessary destructors.
11536 Simplify code with YYCHK.
11537 * tests/glr-regression.at (Corrupted semantic options if user action
11538 cuts parse): New test case.
11539 (Undesirable destructors if user action cuts parse): New test case.
11540 Before applying any of this patch, this test case never actually failed
11541 for me... but only because the corrupted semantic options usually
11542 masked this bug.
11543 (Leaked merged semantic value if user action cuts parse): New test
11544 case.

12427 Instead, reallocate buffers twice as big each time, so that
12428 we waste at most half the allocated memory. Start with a small

12645 All callers changed to avoid the newline.
12646 (yyprocessOneStack): Output two lines rather than one, to accommodate
12647 the above change. This changes the debug output format slightly.

12668 AT_PARSER_CHECK for data that contains backslashes. It currently
12669 uses 'echo', and 'echo' isn't portable if its argument contains
12670 backslashes. Problem found on OpenBSD 3.4. Also, do not assume
12671 that the byte '\0xff' is not printable in the C locale; it is,
12672 under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
12673 not printable, so use '\0x81' to test.

12730 it's error-prone and "make maintainer-distcheck" rejects it.

12802 removed once the bison-runtime domain has been translated by each
12803 team.
12804
12805 * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,
12806 now that token names are already quoted.

12832 the 2005-04-17 change, which is now accomplished (mostly) via
12833 changes in the parsers as described above.

12839 Fix more problems reported by twlevo@xs4all.nl.
12840 * tests/cxx-type.at: Don't pipe output of ./types through sed to
12841 remove trailing spaces. This loses the exit status of ./types,
12842 and isn't needed since ./types shouldn't be emitting trailing
12843 spaces.

12861 to FILE * parameter, not to stderr. This fixes a typo introduced
12862 in the 2005-07-12 change.

12928 Fix typos in explanations of the runtime file.

12931 for backward-compatible bison-runtime.po files in a different way.
12932 * data/glr.c (YY_): New macro, from yacc.c.
12933 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
12934 Translate messages intended for users.

12936 the wording in the other skeletons. We don't know that the memory
12937 is virtual.

12947 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
12948 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
12949 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.

12973 if YYABORT is used).
12974 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with

13012 for compatibility with POSIX 1003.1-2001 (if running coreutils).
13013 * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
13014 Use a destructor, so that we can expand the stack. Change
13015 YYSTYPE to char * so that we can free it. Cast result of malloc.

13746 Remove uses of 'short int' and 'unsigned short int'. This raises
13747 some arbitrary limits. It uses more memory but nowadays that's
13748 not much of an issue.
13749
13750 This change does not affect the generated parsers; that's a different
13751 task, as some users will want to conserve memory there.
13752
13753 Ideally we should use size_t to represent all object counts, and
13754 something like ptrdiff_t to represent signed differences of object

14154 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
14155 whether the reducion was empty or not. This leaves room to
14156 improve the use of YYLLOC_DEFAULT in such a case.
14157 lalr1.cc is still experimental, so changing this is acceptable.
14158 And finally, there are probably not many users who changed the
14159 handling of locations in GLR, so changing is admissible too.

14307 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
14308 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
14309 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
14310 the extra Bison directives instead of the whole series.
14311 Change the grammar so that there are recoverable errors, and
14312 unrecoverable errors. Now we can have the parser give up before
14313 consuming the whole input. As a result we now can observe that
14314 the lookahead is freed when needed.
14315 Change the parser source to parse argv[1] instead of a hard coded
14316 string.
14317 Simplify yylex, and give a value and location to EOF.
14318 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
14319 passed directives already coded in the file.
14320 Add some tests to check the location of "error".
14321 For some tests, the C++ parser is correct, and not yacc.c.
14322 For other tests, they provide different, but unsatisfying, values,
14323 so keep the C++ value so that at least one parser is "correct"
14324 according to the test suite.
14325 (Actions after errors): Remove, this is subsumed by the
14326 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

14504 Spent a few hours checking out which prerequisite versions the
14505 current sources actually require. I went all the way back to
14506 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
14507 a seemingly endless set of combinations of versions more recent
14508 than that. The bottom line is that the current sources require
14509 fairly recent versions of the build tools, and it'll be some work
14510 to change this.
14511 * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
14512 (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
14513 (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
14514 Add comments explaining why those particular versions are
14515 currently needed.

15026 When reducing initial empty rules, Bison parser read an initial
15027 location that is not defined. This results in garbage, and that
15028 affects Bison's own parser. Therefore we need (i) to extend Bison

15325 The problem was that GLR parsers did not conform to the C standard,
15326 because actions like { $1 = $2 + $3; } expanded to expressions
15327 that invoked YYFILL in separate subexpressions, and YYFILL assigned
15328 to a local variable. The C standard says that expressions
15329 like (var = f ()) + (var = f ()) have undefined behavior.
15330 Another problem was that GCC sometimes issues warnings that
15331 yyfill and its parameters are unused.
15332
15333 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
15334 as possibly unused.
15335 (yyfill): New function.
15336 (YYFILL): Use it.
15337 (yyuserAction): Change type of yynormal to bool, so that it matches
15338 the new yyfill signature. Mark it as possibly unused.
15339

15341 Follow up on a bug I reported in February, where a Bison-generated
15342 parser can loop. Provide a test case and a fix for yacc.c. I
15343 don't have a fix for lalr1.cc or for glr.c, unfortunately.
15344 The original bug report is in:

15346
15347 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
15348 macro's size was becoming unwieldy.
15349 (yyerrlab): Do not discard an empty lookahead symbol, as this
15350 might destroy garbage.
15351 (yyerrorlab): New label, with the old contents of YYERROR,
15352 plus the following change: pop the stack of rhs corresponding
15353 to the production that invoked YYERROR. That is how Yacc
15354 behaves, and POSIX requires this behavior.
15355 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
15356 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
15357 Define 'alarm' to do nothing if unistd.h is not available.
15358 Add a new rule "exp: '-' error;" to test the above change to
15359 data/yacc.c. Use 'alarm' to abort any test taking longer than
15360 10 seconds, as it's probably looping.
15361 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
15362 Also, the new yacc.c generates two fewer diagnostics for an
15363 existing test.

15991 we don't need to worry about yyerrlab1 being reported as an
15992 "unused label" by non-GCC C compilers. The downside is that if
15993 locations are used then a couple of statements are duplicated each
15994 time YYERROR is invoked, but the upside is that the warnings
15995 should vanish.

16013 popped). This means that the initial elements will not be freed
16014 explicitly, as is the case in yacc.c; it is not a problem, as
16015 these elements have fake values.

16126 * src/conflicts.c (conflict_report):
16127 Renamed from conflict_report_yacc, removing the old
16128 'conflict_report'. Translate the entire conflict report at once,
16129 so that we don't assume that "," has the same interpretation in
16130 all languages.
16131 (conflicts_output): Use Yacc-style conflict report for each state,
16132 instead of our more-complicated style.
16133 (conflicts_print): Use Yacc-style conflict report, except print
16134 the input file name when not emulating Yacc.

16148 Fix a bug where error locations were not being recorded correctly.
16149 This problem was originally reported by Paul Hilfinger in

16152 * data/yacc.c (yyparse): New local var yylerrsp, to record the
16153 top of the location stack's error locations.
16154 (yyerrlab): Set it. When discarding a token, push its location
16155 onto yylerrsp so that we don't lose track of the error's end.
16156 (yyerrlab1): Now is only the target of YYERROR, so that we can
16157 properly record the location of the action that failed. For GCC
16158 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
16159 GCC warning about yyerrlab1 being unused if YYERROR is unused.
16160 (yyerrlab2): New label, which yyerrlab now falls through to.
16161 Compute the error's location by applying YYLLOC_DEFAULT to
16162 the locations of all the symbols that went into the error.
16163 * doc/bison.texinfo (Location Default Action): Mention that
16164 YYLLOC_DEFAULT is also invoked for syntax errors.
16165 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
16166 Error locations include the locations of all the tokens that were
16167 discarded, not just the last token.

16224 If the user does not define YYSTYPE as a macro, Bison now declares it
16225 using typedef instead of defining it as a macro. POSIX requires this.
16226 For consistency, YYLTYPE is also declared instead of defined.
16227
16228 %union directives can now have a tag before the `{', e.g., the
16229 directive `%union foo {...}' now generates the C code
16230 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
16231 The default union tag is `YYSTYPE', for compatibility with Solaris 9
16232 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
16233 instead of `yyltype'.
16234
16235 `yystype' and `yyltype' are now obsolescent macros instead of being
16236 typedefs or tags; they are no longer documented and will be
16237 withdrawn in a future release.

16242 (struct YYLTYPE): Renamed from struct yyltype.
16243 (YYLTYPE): Renamed from yyltype.
16244 (yyltype, yystype): New (and obsolescent) macros,
16245 for backward compatibility.
16246 * data/yacc.c: Likewise.
16247
16248 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
16249 does not specify a union tag. This is for compatibility with
16250 Solaris 9 yacc.
16251
16252 * src/parse-gram.y (add_param): 2nd arg is now char * not char

16340
16341 Remove unportable casts and storage allocation tricks.
16342 While we're at it, remove almost all casts, since they
16343 usually aren't needed and are a sign of trouble.
16344
16345 * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
16346
16347 * src/derives.c (derives_compute): Do not subtract NTOKENS from
16348 the pointer DSET returned by malloc; this isn't portable.
16349 Instead, always use DSET[i - NTOKENS] rather than DSET[i].
16350 Similarly for DERIVES.
16351 * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
16352 * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
16353 * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
16354
16355 * src/derives.c (derives_compute): Do not bother invoking
16356 int_of_rule_number, since rule numbers are integers.
16357
16358 * src/files.c (concat2, tr, compute_base_name): Use xmalloc (N)
16359 rather than XMALLOC (char, N).
16360
16361 * src/files.c (filename_split): Rewrite to avoid cast.
16362
16363 * src/gram.h (symbol_number_as_item_number,
16364 item_number_as_symbol_number, rule_number_as_item_number,
16365 item_number_as_rule_number):
16366 Now inline functions rather than macros, to avoid casts.
16367 * src/state.h (state_number_as_int): Likewise.
16368 * src/tables.c (state_number_to_vector_number,
16369 symbol_number_to_vector_number): Likewise.
16370
16371 * src/gram.h (int_of_rule_number): Remove; no longer used.
16372
16373 * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,
16374 since the resulting storage is always stored into.
16375
16376 * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place
16377 where it's needed.
16378
16379 * src/muscle_tab.c (muscle_m4_output):
16380 Now inline. Return bool, not int.
16381 * src/state.c (state_compare): Likewise.
16382 * src/symtab.c (symbol_check_defined,
16383 symbol_check_alias_consistency, symbol_pack, symbol_translation,
16384 hash_compare_symbol, hash_symbol):
16385 Likewise.
16386 * src/uniqstr.c (uniqstr_print): Likewise.
16387 * src/muscle_tab.c (muscle_m4_output_processor):
16388 New function, to avoid casts.
16389 * src/state.c (state_comparator, stage_hasher): Likewise.
16390 * src/symtab.c (symbol_check_defined_processor,
16391 symbol_check_alias_consistency_processor, symbol_pack_processor,
16392 symbol_translation_processor, hash_symbol_comparator,
16393 hash_symbol_hasher): Likewise.
16394 * src/uniqstr.c (uniqstr_print_processor): Likewise.
16395 * src/muscle_tab.c (muscles_m4_output):
16396 Use new functions instead of casting old functions unportably.
16397 * src/state.c (state_hash_new): Likewise.
16398 * src/symtab.c (symbols_new, symbols_do, symbols_check_defined,
16399 symbols_token_translations_init):
16400 Likewise.
16401 * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
16402
16403 * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local
16404 var instead of casting to long, to avoid casts.
16405 (prepare_states): Use MALLOC rather than alloca, so that we don't
16406 have to worry about alloca.
16407 * src/state.c (state_hash_lookup): Likewise.
16408
16409 * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
16410 local var instead of casting to unsigned char, to avoid casts.
16411
16412 * src/state.c (TRANSITIONS_ALLOC, ERRS_ALLOC, REDUCTIONS_ALLOC,
16413 STATE_ALLOC): Remove.
16414 (transitions_new, errs_new, reductions_new, state_new): Use malloc
16415 rather than calloc, and use offsetof to avoid allocating slightly
16416 too much storage.
16417 (state_new): Initialize all members.
16418
16419 * src/state.c (state_hash): Use unsigned accumulator, not signed.
16420
16421 * src/symtab.c (symbol_free): Remove; unused.
16422 (symbol_get): Remove cast in lhs of assignment.
16423 (symbols_do): Now static. Accept generic arguments, not

16425
16426 * src/symtab.h: (NUMBER_UNDEFINED): Remove unnecessary cast.
16427 (symbol_processor): Remove.
16428 (symbols_do): Remove decl; now static.

16432 (<inttypes.>, <stdint.h>): Include if available.
16433 (uintptr_t): New type, if system lacks it.
16434 (CALLOC, MALLOC, REALLOC): New macros.
16435 All uses of XCALLOC, XMALLOC, and XREALLOC changed to use these
16436 new macros.
16437
16438 * src/tables.c (table_size): Now int, to pacify GCC.
16439 (table_grow, table_ninf_remap): Use signed table size.
16440 (save_row): Don't bother initializing locals when not needed.
16441 (default_goto, goto_actions, pack_vector): Remove unnecessary casts.
16442 * src/uniqstr.c (hash_compare_uniqstr): Likewise.
16443
16444 * src/vcg.h: Correct misspellings.
16445
16446 * src/vcg_defaults.h (G_CMAX): Now INT_MAX.

16453 Change identifier spellings to avoid collisions with names
16454 that are reserved by POSIX.
16455
16456 Don't use names ending in _t, since POSIX reserves them.
16457 For consistency, remove _e and _s endings -- they're weren't
16458 needed to remove ambiguity. All uses changed.

16460 turn was just renamed from struniq_t.

daa33def 17025 * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
8fcc7db1 17026 -o c"; the HP C compiler chatters during compilation.
daa33def
PE
17027 Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".

17029
17030 * tests/input.at (Torturing the Scanner): Remove lines containing
8fcc7db1 17031 solitary backslashes, as they tickle a bug in the HP C compiler.

17057 to avoid shadowing warnings by GCC.
17058
17059 * data/glr.c (inline): Remove #define. It's the user's
17060 responsibility to #define it away, just like 'const'.
464c6927 17061 This fixes one of the bugs reported by Nelson H. F. Beebe in

17068 Look for N_ as well as for _. Try to avoid matching #define for
17069 N_ and _.
17070 * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
17071 src/system.h. Add src/parse-gram.y, src/scan-gram.l.
17072 * src/scan-gram.l: Revamp regular expressions so that " and '
17073 do not confuse xgettext.
17074
17075 * src/struniq.h (struniq_new): Do not declare the return type

17230 Use new @ escapes consistently. Represent brackets with @{ and @}
17231 rather than @<:@ and @:>@, since this works a bit better with dumb
17232 editors like vi. Represent @ with @@, since @ is now consistently
17233 an escape. Use @oline@ and @ofile@ rather than __oline__ and
17234 __ofile__, to avoid unexpected expansions. Similarly, use @output
17235 rather than #output.
17236
17237 * data/c.m4 (b4_copyright): Omit file name from comment, since
17238 the file name could contain "*/".
17239 (b4_synclines_flag): Don't quote the 2nd argument; it should already
17240 be quoted. All uses changed.
17241
17242 * data/glr.c: Use new @ escapes consistently.
17243 (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,

17251 * src/files.h: Likewise.
17252
17253 * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
17254 mishandled funny characters in file names, and anyway it isn't
17255 needed any more.
17256 * data/yacc.c: Likewise.
17257 * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
17258
17259 * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
17260 * data/yacc.c: Likewise.
17261
17262 * src/muscle_tab.c: Include quotearg.h, since we need to quote C
17263 strings now.
17264 (muscle_init): Quote filename as a C string.
17265 * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
17266 (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.

17268 (prepare_symbols): Quote tokens for M4.
17269 (prepare): Don't insert output_infix, output_prefix,
17270 output_parser_name, output_header_name; this is now down by scan-skel.
17271 Insert skeleton as a C string.
17272
17273 * src/output.c (user_actions_output, symbol_destructors_output,
17274 symbol_printers_output): Quote filenames for C and M4.
17275 * src/reader.c (prologue_augment, epilogue_set): Likewise.
17276
17277 * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
17278 escapes other than \\ and \'; this simplifies the code.
17279 (<SC_STRING>): Likewise, for \\ and \".
17280 (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
17281 SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
17282 Use new escapes @{ and @} for [ and ].
17283
17284 * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
17285 them with auto vars.
17286 Switch to new escape scheme, where @ is the escape character uniformly.
17287 Abort if a stray escape character is found. Avoid unbounded input
17288 buffer when parsing non-escaped text.

17300 (yygetLRActions, yyrecoverParseError): Use them.
17301
17302 * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
17303 counted in the token inserted at end of file. Now takes
17304 location_t *, not location_t, so that the location can be
17305 adjusted. All uses changed.
17306

17311 AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
17312 AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
17313 abort ();'. This reduces the runtime of the "Many lookaheads"
17314 test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running

17574 indicates one.
17575 * src/output.c (output_skeleton): Use xfclose rather than fclose

17642 The last OS that we could find where this wouldn't work is
17643 SunOS 3.5, and that's too old to worry about now.
17644
17645 * data/glr.c (struct yyltype): Define members even when not

18019 Let nondeterministic skeletons be usable with deterministic
18020 tables.
18021
18022 With the patch, GAWK compiled by GCC without -O2 passes its test
18023 suite using a GLR parser driven by LALR tables. It fails with -O2
18024 because `struct stat' gives two different answers on my machine:
18025 88 (definition of an auto var) and later 96 (memset on this var).
18026 Hence the stack is badly corrumpted. The headers inclusion is to

18028 inclusion, the two struct stat have the same size.

18139 Portability fixes for bitsets; this also avoids several GCC
18140 warnings.
18141
18142 * lib/abitset.c: Include <stddef.h>, for offsetof.
18143 * lib/lbitset.c: Likewise.
18144
18145 * lib/abitset.c (abitset_bytes): Return a size that is aligned
18146 properly for vectors of objects. Do not assume that adding a
18147 header size to a multiple of a word size yields a value that is
18148 properly aligned for the whole union.
18149 * lib/bitsetv.c (bitsetv_alloc): Likewise.
18150
18151 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
18152 unique names for structures.
18153 * lib/ebitset.c (ebitset_bytes): Likewise.
18154 * lib/lbitset.c (lbitset_bytes): Likewise.
18155
18156 * lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
18157 abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
18158 abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,

18161 abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
18162 abitset_or_and_cmp, abitset_copy): Supply prototype decls,
18163 to improve the type-checking that GCC can do.
18164 * lib/bitset.c (bitset_op4_cmp): Likewise.
18165 * lib/bitset_stats.c (bitset_stats_count,
18166 bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
18167 bitset_stats_copy, bitset_stats_disjoint_p,

18176 lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
18177 lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
18178 lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.

18181 * lib/ebitset.h: Likewise.
18182 * lib/lbitset.h: Likewise.
18183
18184 * lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
18185 All instances of parameters of type enum bitset_opts are now of
18186 type enum_bitset_opts, to conform to the C Standard, and similarly
18187 for enum_bitset_type.
18188 * lib/ebitset.c (enum_ebitset_find_mode): Likewise.
18189 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
18190
18191 Do not use "struct bitset_struct" to mean different things in
18192 different modules. Not only is this confusing, it violates
18193 the C Standard, which requires that structure types in different
18194 modules must be compatible if one is to be passed to the other.
18195 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
18196 All instances of "struct bitset_struct *" replaced with "bitset".
18197 * lib/bitset.h (struct bitset_struct): Remove, replacing with....
18198 (union bitset_union, struct abitset_struct, struct ebitset_struct,
18199 struct lbitset_struct, struct bitset_stats_struct): New types.
18200 All uses of struct bitset_struct changed to union bitset_union,
18201 etc.
ba0fe3c7 18202 * lib/abitset.c (struct abitset_struct, abitset,
f28a0f2d

18203 struct bitset_struct): Remove.
18204 * lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
18205 struct bitset_struct): Remove.

18207 bitset_struct): Remove.
18208 * lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
18209 Likewise.
18210
18211 Do not call a function of type T using a call that assumes the
18212 function is of a different type U. Standard C requires that a
18213 function must be called with a type that is compatible with its
18214 definition.
18215 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
18216 New decls.
18217 * lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
18218 New functions.
18219 * lib/ebitset.c (PFV): Remove.
18220 * lib/lbitset.c (PFV): Likewise.
18221 * lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
18222 ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
18223 decls.
18224 (ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
18225 (ebitset_vtable): Use them.
18226 * lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
18227 lbitset_xor): New functions.
18228 (lbitset_vtable): Use them.
18229
18230 * lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
18231 Declare.
18232
18233 * lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
18234 GCC warning.
18235 * lib/lbitset.c (LBITSET_CURRENT1): Likewise.
18236 Use offsetof, for simplicity.

18254 fixes.
18255 (Symbols): Mention that any negative value returned from yylex
18256 signifies end-of-input. Warn about negative chars. Mention
18257 the portable Standard C character set.
18258
18259 The GNU coding standard says CFLAGS and YFLAGS are reserved
18260 for the installer to set.

18269 * src/reader.c (reader): Use it.
18270

18272 POSIX 1003.1-2001 has removed fgrep.

18503 same width as int.
18504 (yypstates): Do not assume that ptrdiff_t is the same width
18505 as int, and similarly for yyposn and YYINDEX.
18506
18507 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.

18548 check for void *.
18549
18550 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not

18584 lib/timevar.c.
18585 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
18586 manual recommends.
18587 Similarly, use src/scan-gram.l instead of src/scan-gram.c.

18590 (strerror): Use same pattern as ../lib/error.c.
18591
18592 * src/files.c, src/files.h (compute_header_macro): Remove; unused.

18595

18597 to void, to avoid a GCC warning when --disable-nls is in effect.
18598

18600 to minimize the number of warnings from xgettext.
18601 (handle_action_dollar, handle_action_at): Don't use isdigit,
18602 as it mishandles negative chars and it may not work as expected
18603 outside the C locale.
18604
18605 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
18606 this is a GCC extension and is not portable to other compilers.
18607
18608 * src/system.h (alloca): Use same pattern as ../lib/error.c.
18609 Do not include <ctype.h>; no longer needed.
18610 Do not include <malloc.h>; no longer needed (and generates
18611 warnings on OpenBSD 3.0).
18612
18613 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
18614 it's not portable.
18615
18616 * tests/regression.at: Do not use 'cc -c input.c -o input';
18617 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
18618
18619 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
18620 exit status as failure, not just exit status 1. Sun C exits
18621 with status 2 sometimes.
18622
18623 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
18624 Use it for the two large tests.

21202 Give a try to M4 as a back end.
21203
21204 * lib/readpipe.c: New, from wdiff.
21205 * src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
21206 BISON_HAIRY.
21207 * src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
21208 specific values. Now it is m4 that performs the lookup.
21209 * src/parse-skel.y: Remove.
21210 * src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
21211 * src/output.c (actions_output, guards_output)
21212 (token_definitions_output): No longer keeps track of the output
21213 line number, hence remove the second argument.
21214 (guards_output): Check against the guard member of a rule, not the
21215 action member.
21216 Adjust callers.
21217 (output_skeleton): Don't look for the skeleton location, let m4 do
21218 that.
21219 Create `/tmp/muscles.m4'. This is temporary, a proper temporary
21220 file will be used.
21221 Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
21222 (prepare): Given that for the time being changesyntax is not
21223 usable in M4, rename the muscles using `-' to `_'.
21224 Define `defines_flag', `output_parser_name' and `output_header_name'.
21225 * src/output.h (actions_output, guards_output)
21226 (token_definitions_output): Adjust prototypes.
21227 * src/scan-skel.l: Instead of scanning the skeletons, it now
21228 processes the output of m4: `__oline__' and `#output'.
21229 * data/bison.simple: Adjust to be used by M4(sugar).
21230 * tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
21231 to date.
21232 * tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
21233 instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
21234 * data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
21235 shamelessly stolen from CVS Autoconf.

21493 Don't use %option yylineno: it seems that then Flex imagines
21494 REJECT has been used, and therefore it won't reallocate its

21802 these states are automatically computed from the initial state.
21803 (generate_states): Adjust.
21804 * src/print.c: When reporting a rule number to the user, substract

21841 Be sure to preserve the value of the eoftoken.
21842 (reader): Make sure eoftoken is defined.
21843 Initialize nsyms to 0: now eoftoken is created just like the others.
21844 * src/print.c (print_grammar): Don't special case the eof token.
21845 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
21846 lie anyway, albeit pleasant.
21847 * tests/calc.at: Exercise error messages with eoftoken.
21848 Change the grammar so that empty input is invalid.

25085 The location tracking mechanism is precious for parse error
25086 messages. Nevertheless, it is enabled only when `@n' is used in

25121 Test also `--verbose', `--defines' and `--name-prefix'. Testing
25122 the latter demonstrates a flaw in the handling of non debugging
25123 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
25124 was used in order to simplify:
25125

25135 if (yydebug)

25192 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
25193 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
25194 difficult and introduced a lot of core dump. It turns out that
25195 Bison used an implementation of `xmalloc' based on `calloc', and
25196 at various places it does depend upon the initialization to 0. I
25197 have not tried to isolate the pertinent places, and all the former
25198 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
25199 someone should address this issue.

25570 There is now a pseudo variable @$ (readble and writable), location
25571 of the lhs of the rule (by default ranging from the location of
25572 the first symbol of the rhs, to the location of the last symbol,
25573 or, if the rhs is empty, YYLLOC).
25574
25575 * src/bison.s1 [YYLSP_NEEDED] (yyloc): New variable, twin of
25576 yyval.
25577 (yyparse): When providing a default semantic action, provide a
25578 default location action.
25579 (after the $): No longer change `*YYLSP', just stack YYLOC the
25580 same way you stack YYVAL.
25581 * src/reader.c (read_declarations): Use warns.
25582 (copy_guard, case '@'): Also recognize `@$', expanded as `YYLOC'.
25583 (copy_action, case '@'): Likewise.
25584 Use a standard error message, to save useless work from
25585 translators.

25610 defined only if `YYDEBUG != 0'.

26329 (lex): Use literalchar.
26330 (lex): Implemented "..." tokens.
26331 (literalchar, lex, parse_percent_token): Made tokenbuffer
26332 always contain the token. This includes growing the token
26333 buffer while reading an integer.
26334 (parse_percent_token): Replaced if-else statement with percent_table.
26335 (parse_percent_token): Added % declarations as another
26336 way to specify the flags -n, -l, and -r. Also added hooks for
26337 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
26338 major changes to files.c.
26339 (lex) Retain in the incoming stream a character following
26340 an incorrect '/'.
