- warning.
-
-2011-08-21 Joel E. Denny <joeldenny@joeldenny.org>
-
- tests: add -pedantic for --enable-gcc-warnings.
- This should help to avoid some portability problems. For example,

- * tests/existing.at (GNU Cim Grammar)
- (GNU pic (Groff 1.18.1) Grammar.): Remove empty %union.
-
-2011-07-24 Joel E. Denny <joeldenny@joeldenny.org>
-
- global: remove unnecessary horizontal tabs.
- This change was made by applying emacs' untabify function to
- nearly all files in Bison's repository. Required tabs in make
- files, ChangeLog, regexps, and test code were manually skipped.
- Other notable exceptions and changes are listed below.
- * bootstrap: Skip because we sync this with gnulib.
- * data/m4sugar/foreach.m4
- * data/m4sugar/m4sugar.m4: Skip because we sync these with
- Autoconf.
- * djgpp: Skip because I don't know how to test djgpp properly, and
- this code appears to be unmaintained anyway.
- * README-hacking (Hacking): Specify that tabs should be avoided
- where not required.
-
-2011-07-10 Joel E. Denny <joeldenny@joeldenny.org>
-
- build: avoid YACC typo inherited from Autoconf.
- The typo shows up in the `configure --help' output. Reported by
- W.C.A. Wijngaards and Paul Eggert at
- <http://lists.gnu.org/archive/html/bug-bison/2011-07/msg00000.html>.
- * README-hacking (Release Procedure): Remind about updating
- maintainer tools before a release.
- * THANKS (W.C.A. Wijngaards): Add.
- * configure.ac (AC_PREREQ): Set to 2.68, which fixes the YACC
- typo.
-
-2011-07-10 Joel E. Denny <joeldenny@joeldenny.org>
-
- build: create xz instead of bzip2 tarballs.
- Suggested by Jim Meyering at
- <http://lists.gnu.org/archive/html/bug-bison/2011-06/msg00012.html>.
- * README-hacking (Release Procedure): Update example.
- * configure.ac (AM_INIT_AUTOMAKE): Replace dist-bzip2 with

-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: clean up references to `Locations Overview'.
- * doc/bison.texinfo (Locations Overview): Rename node to...
- (Locations): ... this, which is its section name. Update menus to
- match that and not to use the title `Tracking Locations', which is
- a different section.
-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: clean up references to `Tracking Locations'.
- * doc/bison.texinfo (Locations): Rename node to...
- (Tracking Locations): ... this, which is its section name, and
- update all cross references. The trouble is that there is another
- node about locations. Its section name is `Locations', which was
- easily confused with the node name of this node. Moreover, its
- node name is `Locations Overview', which was mistakenly used to
- label some cross references to this node.
-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: clean up `Named References' a little.
- * doc/bison.texinfo (Named References): Rename section to match
- the node name, and update all cross references. Don't use the
- acronyms RHS and LHS given that we don't expand them anywhere in
- the manual. Try to use @samp and @code properly. Mention that
- named references are experimental as we've already stated in NEWS.
- (Destructor Decl): Expand the only remaining use of RHS or LHS.
-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: motivate named references.
- Suggested by Hans Aberg at
- <http://lists.gnu.org/archive/html/bug-bison/2011-05/msg00008.html>.
- * doc/bison.texinfo (Named References): Explain briefly how
- they're better than the traditional positional references.
-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: discuss named references after locations.
- Reported by Hans Aberg at
- <http://lists.gnu.org/archive/html/bug-bison/2011-05/msg00008.html>.
- * NEWS (2.5.1): Document.
- * doc/bison.texinfo (Named References): Because it discusses
- locations in addition to semantic values, move this subsection out
- of the section `Defining Language Semantics', where locations have
- not yet been introduced, to be a new section after the following
- section, `Tracking Locations'.
-
-2011-05-29 Joel E. Denny <joeldenny@joeldenny.org>
-
- Prepare for the possibility of a 2.5.1 release.
- * NEWS (2.5.1): New heading.
-
-2011-05-14 Joel E. Denny <joeldenny@joeldenny.org>
-
- Version 2.5.
- * NEWS (2.5): Set date.
-
-2011-05-14 Joel E. Denny <joeldenny@joeldenny.org>
-
- Don't use IF_LINT in Bison sources.
- It creates unnecessary differences between the sources that Bison
- maintainers build and test (given that maintainers normally
- configure with --enable-gcc-warnings) and the sources that Bison
- users build. Instead, use PACIFY_CC, which doesn't. This change
- fixes compiler warnings reported by Tys Lefering at
- <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
- * configure.ac: Don't AC_DEFINE lint regardless of the configure
- options. This change affects imported gnulib sources, where
- IF_LINT still appears and depends on lint.
- * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
- PACIFY_CC.
- * src/system.h (IF_LINT): Remove cpp macro.
- (PACIFY_CC): New cpp macro.
-
-2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
-
- Fix precedence for end token.
- Since Bison 2.3b, which restored the ability of precedence
- directives to assign user token numbers, doing so for user token
- number 0 has produced an assertion failure.
- * NEWS (2.5): Document fix.
- * src/symtab.c (symbol_user_token_number_set): In the case of the
- end token, don't decrement ntokens if it was never incremented.
- * tests/regression.at (Token number in precedence declaration):
- Extend.
-
-2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
-
- Pacify -DGNULIB_POSIXCHECK.
- * bootstrap.conf (gnulib_modules): Add all modules suggested by
- -DGNULIB_POSIXCHECK.
- * src/files.c (file_name_split)
- * src/getargs.c (getargs)
- * src/location.c (boundary_set_from_string)
- * src/output.c (output_skeleton)
- * src/parse-gram.y (prologue_declaration)
- * src/scan-gram.l (handle_syncline)
- * src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of
- strchr and strrchr. In the cases of command-line options, file
- names, and thus locations, functionality may be improved. In the
- case of symbol names, there should be no functional difference as
- all characters are ASCII, so the intended benefit is just warning
- suppression.
-
-2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
-
- * NEWS (2.5): Fix minor typos.
-
-2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: clean up quotation style in NEWS.
- * NEWS (2.5): For multi-character tokens in example grammar rules,
- use "token" not 'token'. In English, use a consistent quotation
- style; we might as well follow the precedent seen in info pages:
- `quote' not "quote".
-
-2011-04-16 Joel E. Denny <joeldenny@joeldenny.org>
-
- tests: pacify gcc 4.6.0's -Wunused-but-set-variable.
- Reported by Jim Meyering at
- <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>.
- * tests/actions.at
- (Default %printer and %destructor for mid-rule values): Define
- YYLLOC_DEFAULT so that it uses its Rhs argument.
-
-2011-04-16 Joel E. Denny <joeldenny@joeldenny.org>
-
- glr.c: omit yyresolveLocations when locations are disabled.
- This prevents gcc 4.6.0's -Wunused-but-set-variable from warning
- about yyresolveLocations's local yyrhsloc. When locations are
- enabled, there's no such warning because YYLLOC_DEFAULT then uses
- yyrhsloc. Reported by Jim Meyering at
- <http://lists.gnu.org/archive/html/bug-bison/2011-04/msg00002.html>.
- * data/glr.c (yyresolveLocations): Omit definition when locations
- are disabled.
- (yyresolveValue): Omit yyresolveLocations invocation when
- locations are disabled.
-
-2011-04-16 Joel E. Denny <joeldenny@joeldenny.org>
-
- gnulib, autoconf: update.
- * README-hacking (Updating a submodule): Give advice on how to
- determine the versions of gnulib and autoconf to which we should
- update.
- (Release Procedure): Note that submodules should be updated.
- * bootstrap.conf (gnulib_modules): Rename pipe to spawn-pipe as
- suggested in updated gnulib NEWS.
- * gnulib: Choose a stable snapshot according to advice in Bison's
- README-hacking.
- * po/POTFILES.in (lib/pipe.c): Rename to...
- (lib/spawn-pipe.c): ... this.
- * src/output.c: Update to include spawn-pipe.h.
- * submodules/autoconf: Update to latest for improvement in m4.m4
- that excludes M4 with buggy strstr. The only other changes to
- files that we use are copyright updates.
-
-2011-04-09 Joel E. Denny <joeldenny@joeldenny.org>
-
- Fix missing updates to GPLv3.
- Reported by Tys Lefering at
- <http://lists.gnu.org/archive/html/bison-patches/2011-04/msg00000.html>.

-
-2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>

- Thus, conflict reports are now affected by -Werror and -Wnone
- (unless %expect or %expect-rr is specified). Reported by George
- Neuner at

- warnings_conflicts_sr and warnings_conflicts_rr as well.
- (warnings_args, warnings_types): Add entries for
- warnings_conflicts_sr and warnings_conflicts_rr.
- (usage): Update.
- * src/getargs.h (enum warnings): Add entries for
- warnings_conflicts_sr and warnings_conflicts_rr.
- * tests/conflicts.at (-W versus %expect and %expect-rr): New test
- group.
- * tests/local.at (AT_BISON_CHECK_NO_XML): Update now that the
- conflict report can produce a "warnings being treated as errors"
- message. Also, check that stderr is now fully scrubbed by -Wnone
- when the exit status is 0.
-
-2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>
-
- Pacify maintainer-check-posix.
- Adding command-line options after the grammar file name is not
- permitted, so disable checks that do that when
- maintainer-check-posix is running.
- * tests/local.at (AT_BISON_CHECK_NO_XML): Don't run the
- problematic checks when POSIXLY_CORRECT=1. Also, for readability,
- remove an unnecessary m4_if.
-
-2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>
-
- Add -Wother so -Wnone suppresses all warnings.
- Reported by George Neuner at
- <http://lists.gnu.org/archive/html/bug-bison/2010-08/msg00002.html>.

- that it's controlled by its own warning category.
- * src/getargs.c (warnings_flag): Initialize to warnings_other.
- (warnings_args, warnings_types): Add entry for warnings_other.
- (usage): Update.
- * src/getargs.h (enum warnings): Add entry for warnings_other.
- * src/gram.c (grammar_rules_useless_report): If -Wno-other, then
- don't print useless rules.
- * src/reader.c (symbol_should_be_used): Rather than adjusting the
- return value based on whether midrule value warnings are enabled,
- accept a new parameter for telling the caller whether true is
- being returned for a potential midrule warning.
- (grammar_rule_check): Use midrule_value_at for midrule value
- warnings, and continue to use warn_at for all other warnings. Let
- them check whether the warnings are enabled.
- * tests/local.at (AT_BISON_CHECK): Update documentation.
- (AT_BISON_CHECK_NO_XML): Check that -Wnone and --warnings=none
- disable all warnings exercised in the test suite.
-
-2011-03-27 Joel E. Denny <joeldenny@joeldenny.org>

-2011-03-20 Joel E. Denny <joeldenny@joeldenny.org>
-
- lr.default-reductions: rename "full" value to "most".

- * THANKS (Angelo Borsotti): Add.

-
-2011-03-06 Joel E. Denny <joeldenny@joeldenny.org>
-
- lr.default-reductions: rename "all" value to "full".

- And clean up all other documentation of the features described
- there.
- * NEWS (2.5): Tweak wording of lr.type and parse.lac entries a
- bit, update the cross-references to the manual, and point out that
- LAC has caveats. Don't be so adamant that IELR+LAC=canonical LR.
- That is, as the referenced section in the manual documents, LAC
- does not fix infinite parsing loops on syntax errors.
- * doc/bison.texinfo: Consistently drop the "(1)" suffix from LALR,
- IELR, and LR in @cindex.
- (%define Summary): Condense the entries for lr.default-reductions,
- lr.keep-unreachable-states, lr.type, and parse.lac into brief
- summaries, and cross-reference the appropriate subsections of
- Tuning LR. For parse.lac, mention that it's only implemented for

- and add cross-reference to the LAC section.
- (Error Reporting): When mentioning parse.error, mention LAC, and
- add cross-reference to the LAC section.

- documentation removed from %define Summary. Change all
- cross-references in the manual to point here instead of there.
- (Calc++ Parser): When mentioning parse.error, mention LAC, and add
- cross-reference to the LAC section.
- (Table of Symbols): In %error-verbose entry, add cross-reference
- to Error Reporting.

- for "defaulted state" and "unreachable state". Expand IELR
- acronym in IELR's entry.
-
-2011-02-20 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: add bibliography to manual.

- a separate section. For example, add an intro, and move most of
- the text outside of the @deffn so it is not indented so far.
- (%code Summary): Likewise.
- (Table of Symbols): Reword %code entry to match the %code entry in
- Decl Summary.

- * doc/bison.texinfo (Decl Summary): Extract most of the %define
- entry into...
- (%define Summary): ... this new subsection, and update all
- cross-references. For readability of the patches, rewriting of
- the text so it makes sense as a separate subsection will come in a
- later patch. Moreover, the majority of the text describing the
- various new LR features should likely move to another new section
- somewhere.

-
- doc: clean up naming of various Bison files.
- The Bison manual's names for various files associated with a Bison
- parser has devolved into inconsistency. This patch makes the
- naming consistent for the most important files. First, it chooses
- "grammar file" over "input file". The former appears to be more
- traditional in the Bison manual, and Bison has other input
- files (skeletons). Second, it chooses "parser implementation
- file" over names like "parser file", "parser source file", "parser
- source code file", and "parser output file". The new name makes
- it clearer where Bison generates the main parser implementation,
- and it is easily distinguishable from "parser header file".
- * doc/bison.texinfo: Implement throughout.
-
-2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: give credit to more of Bison's developers.
- * doc/bison.texinfo (Introduction): Don't imply that only Robert
- Corbett, Richard Stallman, and Wilfred Hansen have contributed to
- Bison. However, I don't have time to write a full history, so
- just point readers to THANKS and ChangeLog.
-
-2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: document experimental features better.
- * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
- LR(1) are experimental. Mention Java. Normally experimental
- features probably shouldn't be mentioned in the introduction.
- However, if Bison's limitations to LALR(1), C, and C++ are so
- important that they should be mentioned here, then it's important
- to point out that Bison is beginning to escape those limitations.
- Moreover, these particular experimental features have very little
- chance of being removed.
- * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
- experimental.

-
- Do not allow identifiers that start with a dash.
- This cleans up our previous fixes for a bug whereby Bison
- discarded `.field' in `$-1.field'. The previous fixes were less
- restrictive about where a dash could appear in an identifier, but
- the restrictions were hard to explain. That bug was reported and
- this final fix was originally suggested by Paul Hilfinger. This
- also fixes a remaining bug reported by Paul Eggert whereby Bison
- parses `%token ID -123' as `%token ID - 123' and handles `-' as an
- identifier. Now, `-' cannot be an identifier. Discussed in
- threads beginning at
- <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
- <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
- * NEWS (2.5): Update entry describing the dash extension to
- grammar symbol names. Also, move that entry before the named
- references entry because the latter mentions the former.
- * doc/bison.texinfo (Symbol): Update documentation for symbol
- names. As suggested by Paul Eggert, mention the effect of periods
- and dashes on named references.
- (Decl Summary): Update documentation for unquoted %define values,
- which, as a side effect, can no longer start with dashes either.
- * src/scan-code.l (id): Implement.
- * src/scan-gram.l (id): Implement.
- * tests/actions.at (Exotic Dollars): Extend test group to exercise
- bug reported by Paul Hilfinger.
- * tests/input.at (Symbols): Update test group, and extend to
- exercise bug reported by Paul Eggert.
- * tests/named-refs.at (Stray symbols in brackets): Update test
- group.
- ($ or @ followed by . or -): Likewise.
- * tests/regression.at (Invalid inputs): Likewise.
-
-2011-01-24 Joel E. Denny <joeldenny@joeldenny.org>
-
- * data/yacc.c: Fix last apostrophe warning from xgettext.
-
-2011-01-09 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix minor problems encountered by a fresh bootstrap.
- * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
- as they confuse xgettext, which tries to parse them as C character
- constants in a preprocessor directive.
- * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as
- that expression might not promote to int on some platforms.
- * src/parse-gram.c, src/parse-gram.h: Regenerate.
-
-2011-01-09 Joel E. Denny <joeldenny@joeldenny.org>
-
- Improve error messages for `$' or `@' followed by `.' or `-'.
- Previously, for this special case of an invalid reference, the
- usual "symbol not found in production:" was printed. However,
- because the symbol name was parsed as the empty string, that
- message was followed immediately by a newline instead of a symbol
- name. In reality, this is a syntax error, so the reference is
- invalid regardless of the symbols actually appearing in the
- production. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
- * src/scan-code.l (parse_ref): Report the above case as a syntax
- error. Other than that, continue to handle this case like any
- other invalid reference that Bison manages to parse because
- "possibly meant" messages can still be helpful to the user.
- * tests/named-refs.at ($ or @ followed by . or -): New test group.
-
-2011-01-08 Joel E. Denny <joeldenny@joeldenny.org>
-
- doc: don't use @acronym.
- Lately, many GNU packages are dropping it. See
- <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00003.html>.
- * doc/bison.texinfo: Remove all uses.
-
-2011-01-05 Alex Rozenman <rozenman@gmail.com>
-
- Do not allow identifiers that start with a negative number.
- Reported by Paul Hilfinger as a side effect of named references
- support at
- <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>.
- Suggested by Paul Eggert.
- * src/scan-code.l ({letter}, {id}): Adjust lexical definitions.
- * src/scan-gram.l ({letter}, {id}): Likewise.

- * NEWS (2.5): Add entry for LAC, and mention LAC in entry for
- other corrections to verbose syntax error messages.
- * doc/bison.texinfo (Decl Summary): Rewrite entries for

- %nonassoc's effect on canonical LR, and to mention LAC. Add entry
- for parse.lac.
- (Glossary): Add entry for LAC.
-
-2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
-
- parse.lac: implement exploratory stack reallocations.
- * data/yacc.c: Rename %define variable parse.lac.es-capacity to
- parse.lac.es-capacity-initial. Accept parse.lac.memory-trace
- with values of "failures" (default) or "full".
- (b4_declare_parser_state_variables): Add yyesa, yyes, and
- yyes_capacity variables.
- (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
- (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
- LAC requested.
- (YYCOPY_NEEDED): New cpp macro.
- (YYCOPY): Define if LAC requested.
- (yy_lac_stack_realloc): New function implementing stack
- reallocations. Use YYMAXDEPTH for maximum stack size given that
- the stack should never need to grow larger than the main state
- stack needs to grow without LAC.
- (YY_LAC_ESTABLISH): Update yy_lac invocation.
- (yy_lac): Add arguments for exploratory stack memory data
- recorded in the main parser. Invoke yy_lac_stack_realloc when
- reallocation is necessary.
- (yysyntax_error): Add the same new arguments and pass them to
- yy_lac.
- (yypstate_delete): Free yyes if necessary.
- (yyesa, yyes, yyes_capacity): #define these to yypstate members
- in the case of push parsing.
- (yyparse, yypush_parse): Initialize yyes and yyes_capacity.
- Update yysyntax_error invocations. At yyreturn, free yyes if
- necessary.
- * src/parse-gram.y: %define parse.lac full.
- * tests/input.at (LAC: errors for %define): Extend for
- parse.lac-memory-trace.
- * tests/regression.at (LAC: Exploratory stack): Extend to check
- that stack reallocs happen when expected.
- (LAC: Memory exhaustion): Update to use YYMAXDEPTH and
- parse.lac.es-capacity-initial.
-
-2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
-
- parse.lac: implement as %define variable.
- LAC = lookahead correction. See discussion at
- <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
- However, one point there must be corrected: because of %nonassoc,
- LAC is *not* always redundant for lr.type=canonical-lr.
- * data/yacc.c: Accept values of "none" (default) or "full" for
- parse.lac. Accept %define parse.lac.es-capacity to specify
- capacity of LAC's temporary exploratory stack. It defaults to 20
- and, for now, will not grow dynamically.
- (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
- parse.lac!=none.
- (YYBACKUP): Invoke YY_LAC_DISCARD.
- (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
- yy_lac and track when it needs to be invoked
- (yy_lac): New function that, given the current stack, determines
- whether a token can eventually be shifted. Return status mimics
- yyparse return status.
- (yysyntax_error): Change yystate argument to yyssp so stack top
- can be passed to yy_lac. If LAC is requested, build expected
- token list by invoking yy_lac for every token instead of just
- checking the current state for lookaheads. Return 2 if yy_lac
- exhausts memory.
- (yyparse, yypush_parse): Use local variable yy_lac_established and
- cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
- Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
- is requested.
- * tests/conflicts.at (%nonassoc and eof): Extend to check the
- effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
- (parse.error=verbose and consistent errors): Likewise.
- (LAC: %nonassoc requires splitting canonical LR states): New test
- group demonstrating how LAC can fix canonical LR.
- * tests/input.at (LAC: Errors for %define): New test group.
- * tests/regression.at (LAC: Exploratory stack): New test group.
- (LAC: Memory exhaustion): New test group.

-
- build: use gnulib's new bootstrap_sync option.
- Now, whenever we update bison's copy of gnulib, bootstrap will
- update itself the next time it's run.
- * bootstrap: Copy from latest gnulib for bootstrap_sync support.
- * bootstrap.conf (bootstrap_sync): Set to true.
- * gnulib: Update to latest so bootstrap is in sync now.
-
-2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
-
- yysyntax_error: fix for consistent error with lookahead.
- * NEWS (2.5): Document.
- * data/yacc.c (yysyntax_error): In a verbose syntax error
- message while in a consistent state with a default action (which
- must be an error action given that yysyntax_error is being
- invoked), continue to drop the expected token list, but don't
- drop the unexpected token unless there actually is no lookahead.
- Moreover, handle that internally instead of returning 1 to tell
- the caller to do it. With that meaning of 1 gone, renumber
- return codes more usefully.
- (yyparse, yypush_parse): Update yysyntax_error usage. Most
- importantly, set yytoken to YYEMPTY when there's no lookahead.
- * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
- unexpected token unless there actually is no lookahead.
- * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
- pass yyempty_ not yyla.type to yysyntax_error_.
- (yy::parser::yysyntax_error_): Again, don't drop the unexpected
- token unless there actually is no lookahead.
- * data/lalr1.java (YYParser::parse): If there's no lookahead,
- set yytoken to yyempty_ before invoking yysyntax_error.
- (YYParser::yysyntax_error): Again, don't drop the unexpected
- token unless there actually is no lookahead.
- * tests/conflicts.at (parse.error=verbose and consistent
- errors): Extend test group to further reveal how the previous
- use of the simple "syntax error" message was too general. Test
- yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
- failure.
- * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
- to...
- * tests/local.at: ... here.
- (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
- (AT_BISON_OPTION_POPDEFS): Pop it.
- (AT_FULL_COMPILE): Extend to handle Java.
-
-2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>

- * tests/conflicts.at (parse.error=verbose and consistent errors):
- Reorganize.
-
-2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
-
- yysyntax_error: prepare for readability of next patches.
- These are purely whitespace changes that result in ugly code
- but that make the next couple of patches much easier to read.
- * data/glr.c (yyreportSyntaxError): Reindent.
- * data/lalr1.cc (yy::parser::yysyntax_error_): Reindent.
- * data/lalr1.java (YYParser::yysyntax_error): Reindent.
- * data/yacc.c (yysyntax_error): Reindent.

-
-2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
-
- yysyntax_error: improve invocation readability.
- * data/yacc.c (yyparse, yypush_parse): For yysyntax_error
- invocation, get rid of the while loop, which is misleading
- because there are really at most two iterations.
-

-
- Jim Meyering reported this in

- * data/yacc.c: Use EXIT_SUCCESS as a witness for stdlib.h,
- not _STDLIB_H. EXIT_SUCCESS has been defined by the standard
- for quite some time.
- * src/parse-gram.c, src/parse-gram.h: Regenerate.
- * tests/regression.at: Tamper with the renamed witness.
-
- Adjust to recent changes to gnulib bootstrap.
-
- * .cvsignore, build-aux/.cvsignore, doc/.cvsignore, etc/.cvsignore:
- * examples/calc++/.cvsignore, lib/.cvsignore, m4/.cvsignore:
- * po/.cvsignore, runtime-po/.cvsignore, src/.cvsignore:
- * tests/.cvsignore: Remove; I don't use CVS to maintain Bison
- anymore and don't know of anybody else who does. If someone needs
- these files, they can resurrect them.
- * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore:
- * m4/.gitignore, po/.gitignore, runtime-po/.gitignore:
- Omit leading '/', since bootstrap omits it.
- Adjust file names to match current contents better.
- * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook
- installed just for us.
- * bootstrap.conf (excluded_files): Don't exclude codeset.m4,
- glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now
- needed somehow. Don't have time to look into why.
- (gnulib_modules): Change malloc to malloc-gnu. Do we really assume
- the GNU malloc behavior, where malloc (0) != NULL unless we're
- out of storage? If not, we can omit malloc-gnu; but for now I left
- it in to be safe.
- (vc_ignore): Remove.
- (gnulib_mk_hook): New function.
- * README-hacking: Renamed from HACKING, since gnulib bootstrap now
- uses that convention.

- (yyglrReduce): Conditionalize message "Parse ... rejected by rule..."
- on whether we are in split mode, for consistency with behavior of
- non-GLR parsing.
-
-2010-09-01 Akim Demaille <demaille@gostai.com>
-
- Address GCC warnings about shadowed local variables (yyflag).

-
- portability: fix several issues with M4 subprocess.
-
- M4's output pipe was not being drained upon fatal errors during
- scan_skel. As a result, broken-pipe messages from M4 were seen
- on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
- failure in the test suite. The problem was that, on platforms
- where the default disposition for SIGPIPE is ignore instead of
- terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
- then reported it. However, there's some sort of race condition,
- because the new test group occasionally succeeded.
- Reported by Albert Chin at
- <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.
-
- There were also problems with the test suite livelocking on
- Tru64 5.1b. Reported by Didier Godefroy at
- <http://lists.gnu.org/archive/html/bug-bison/2009-05/msg00005.html>.
- Switching to create_pipe_bidi suggested by Akim Demaille.
-
- To attempt to solve both of these problems, switch to gnulib's
- create_pipe_bidi and register M4 process as a slave. Along the
- way, clean up file name conflict handling, which was affected by
- the broken-pipe problem before the switch.

- portability: `<' and `>' are not always defined on addresses.
- Specifically, don't sort objects by their memory addresses when
- they're not allocated in the same array or other object. Though
- I haven't found a test case where that fails on my platform, C

-
- Fix handling of yychar manipulation in user semantic actions.
- The problem was that yacc.c didn't always update the yychar
- translation afterwards. However, other skeletons appear to be
- fine. glr.c appears to already translate yychar before every
- use. lalr1.cc does not define yychar and does not document its
- replacement, yyla, for users. It does provide yyclearin, but
- that does not manipulate yyla and thus requires no translation
- update. In lalr1.java, yychar is out of scope during semantic
- actions.
- * NEWS (2.5): Document.
- * data/yacc.c (YYBACKUP): Don't bother translating yychar into
- yytoken here.
- (yyparse, yypush_parse): Instead, translate before every use of
- yytoken, and add comments explaining this approach.
- * tests/actions.at (Destroying lookahead assigned by semantic
- action): New test group checking that translation happens before
- lookahead destructor calls at parser return. Previously,
- incorrect destructors were called.
- * tests/conflicts.at (parse.error=verbose and consistent
- errors): New test group checking that translation happens at
- syntax error detection before the associated verbose error
- message and the associated lookahead destructor calls. While
- the destructor call is fixed by this patch, the verbose error
- message is currently incorrect due to another bug (see
- comments in test group), so this is an expected failure for now.

- yysyntax_error: avoid duplicate lookahead collection.
- Except when memory reallocation is required, this change
- eliminates the need to invoke yysyntax_error twice and thus to
- repeat the collection of lookaheads. It also prepares for
- future extensions that will make those repetitions more
- expensive and that will require additional memory management in
- yysyntax_error. Finally, it fixes an obscure bug already
- exercised in the test suite.
- * data/yacc.c (yysyntax_error): Add arguments for message
- buffer variables stored in the parser. Instead of size, return
- status similar to yyparse status but indicating success of

-
- More fixes related to last two patches.
- * data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
- comments: zero indicates syntax error not default action.
- * data/c.m4 (b4_table_value_equals): Comment that YYID must be
- defined.
- * data/glr.c (yyis_pact_ninf): Rename to...
- (yypact_value_is_default): ... this.
- (yyisDefaultedState): Update for rename.
- (yyis_table_ninf): Rename to...
- (yytable_value_is_error): ... this, and check for value zero
- besides just YYTABLE_NINF.
- (yygetLRActions): Check for default value from yypact. It
- appears that this check is always performed before this function
- is invoked, and so adding the check here is probably redundant.
- However, the code may evolve after this subtlety is forgotten.
- Also, update for rename to yytable_value_is_error. Because that
- macro now checks for zero, a different but equivalent branch of
- the if-then-else here is evaluated.
- (yyreportSyntaxError): Update for rename to
- yytable_value_is_error. The zero condition was mishandled
- before.
- (yyrecoverSyntaxError): Update for renames. No behavioral
- changes.
- * data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
- New function.

- (parse): Use new functions where possible. No behavioral
- changes.
- (yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.

- The zero condition was mishandled before.
- (yyparse): Update for renames. No behavioral changes.
- * src/tables.h: Improve comments about yypact, yytable, etc.

- Fix complaints about escape sequences.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
- * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
- For a \0 and similar escape sequences meaning the null
- character, report an invalid escape sequence instead of an
- invalid null character because the latter does not actually
- appear in the user's input.
- In all escape sequence complaints, don't escape the initial
- backslash, and don't quote when the sequence appears at the end
- of the complaint line unless there's whitespace that quotearg
- won't escape.
- Consistently say "invalid" not "unrecognized".
- Consistently prefer "empty character literal" over "extra
- characters in character literal" warning for invalid escape
- sequences; that is, consistently discard those sequences.
- * tests/input.at (Bad escapes in literals): New.

- build: fix the generation of the documentation.
- Some of our targets use "bison --help", but they can't depend on
- "bison" itself (to avoid additional requirements on the user), so
- they used to call "make src/bison" in the commands. Then
- concurrent builds may fail: one make might be aiming one of its
- jobs at compiling src/bison, and another job at generating the man
- page. If the latter is faster than the former, then we have two
- makes that concurrently try to compile src/bison.
-
- This might also be a more convincing explanation for the failure
- described in the patch "build: fix paths".

-
- Use the symbol properties to output the printer/destructor for lalr1.cc.
- Instead of defining complex list of tuples to define various
- properties of the symbols, we now prefer to define symbols as
- "structs" in m4: using the symbol key (its number), and the
- property name, b4_symbol gives it value. Use this to handle
- destructors and printers.

-
- Convert lib/Makefile.am into lib/local.mk.
- The real problem is rather gnulib.mk, which itself is extracted
- from a Makefile.am that gnulib expects to the "recursive". The
- tool prefix-gnulib-mk converts such a gnulib.mk to be
- non-recursive. Also, some AC_SUBST variables need to be adjusted.

-
- Get rid of yyrhs and yyprhs in yacc.c.
- They were used to get the symbol types, given a rule number, when
- displaying the top of the stack before a reduction. But the
- symbol type is available from the state stack. This has two be
- benefits: two tables less in the parser (making it smaller), and a
- more consistent use of the three stacks which will help to fuse
- them.

-
- There are two issues to handle: first scanning nested angle
- bracket pairs to support types such as std::pair< std::string,
- std::list<std::string> > >.
-
- Another issue is to address idiosyncracies of C++: do not glue two

- The constructors are called by the make_symbol functions, which a

- putting them together.
-
- The stack_symbol_type does not need to be moved, it is used only
- by the parser.

-
- Finer input type for yytranslate.
- This patch is debatable: the tradition expects yylex to return an int
- which happens to correspond to token_number (which is an enum). This
- allows for instance to return characters (such as '*' etc.). But this
- goes against the stronger typing I am trying to have with the new
- lex interface which return a symbol_type. So in this case, feed
- yytranslate_ with a token_type.
-
- * data/lalr1.cc (yytranslate_): When in %define lex-symbol,

- Define the "identifier" of a symbol.
- Symbols may have several string representations, for instance if

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

- Change the handling of the symbols in the skeletons.
- Before we were using tables which lines were the symbols and which
- columns were things like number, tag, type-name etc. It is was
- difficult to extend: each time a column was added, all the numbers had
- to be updated (you asked for colon $2, not for "tag"). Also, it was
- hard to filter these tables when only a subset of the symbols (say the
- tokens, or the nterms, or the tokens that have and external number
- *and* a type-name) was of interest.
-
- Now instead of monolithic tables, we define one macro per cell. For
- instance "b4_symbol(0, tag)" is a macro name which contents is
- self-decriptive. The macro "b4_symbol" provides easier access to
- these cells.

-
- Add "%define assert" to variants.
- This is used to help the user catch cases where some value gets
- ovewritten by a new one. This should not happen, as this will
- probably leak.
-
- Unfortunately this uncovered a bug in the C++ parser itself: the
- lookahead value was not destroyed between two calls to yylex. For
- instance if the previous lookahead was a std::string, and then an int,
- then the value of the std::string was correctly taken (i.e., the
- lookahead was now an empty string), but std::string structure itself
- was not reclaimed.
-
- This is now done in variant::build(other&) (which is used to take the
- value of the lookahead): other is not only stolen from its value, it
- is also destroyed. This incurs a new performance penalty of a few
- percent, and union becomes faster again.
-
- * data/lalr1-fusion.cc (variant::build(other&)): Destroy other.

-
- Fuse the three stacks into a single one.
-
- In order to make it easy to perform benchmarks to ensure that
- there are no performance loss, lalr1.cc is forked into
- lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
- lalr1.cc.
-
- Meanwhile, to make sure that lalr1-fusion.cc is correctly
- exercized by the test suite, the user must install a symbolic link
- from lalr1.cc to it.
-
- Instead of having three stacks (state, value, location), use a
- stack of triples. This considerably simplifies the code (and it
- will be easier not to require locations as currently does the C++
- parser), and also gives a 10% speedup according to
- etc/bench (probably mainly since memory allocation is done once
- instead of three times).
-
- Another motivation is to make it easier to destruct properly
- semantic values: now that they are bound to their state (hence
- symbol type) it will be easier to call the appropriate destructor.
-
- These changes should probably benefit the C parser too.
-
- * data/lalr1.cc: Copy as...
- * data/lalr1-fusion.cc: this new file.
- (b4_rhs_value, b4_rhs_location): New definitions overriding those
- from c++.m4.
- (state_stack_type, semantic_stack_type, location_stack_type)
- (yystate_stack_, yysemantic_stack_, yylocation_stack_): Remove.
- (data_type, stack_type, yystack_): New.
- (YYLLOC_DEFAULT, yypush_): Adjust.
- (yyerror_range): Now based on data_type, not location_type.
-
-2008-11-03 Akim Demaille <demaille@gostai.com>
-
- Push the state, value, and location at the same time.
- This is needed to prepare a forthcoming patch that fuses the three
- stacks into one.
-
- * data/lalr1.cc (parser::yypush_): New.
- (parser::yynewstate): Change the semantics: instead of arriving to
- this label when value and location have been pushed, but yystate
- is to be pushed on the state stack, now the three of them must
- have been pushed before. yystate still must be the new state.
- This allows to use yypush_ everywhere instead of individual
- handling of the stacks.

-
- Use variants to support objects as semantic values.
- This patch was inspired by work by Michiel De Wilde. But he used
- Boost variants which (i) requires Boost on the user side, (ii) is
- slow, and (iii) has useless overhead (the parser knows the type of
- the semantic value there is no reason to duplicate this
- information as Boost.Variants do).
-
- This implementation reserves a buffer large enough to store the
- largest objects. yy::variant implements this buffer. It was
- implemented with Quentin Hocquet.
-
- * src/output.c (type_names_output): New.
- (output_skeleton): Invoke it.

- (b4_char_sizeof, yy::variant): New.
- (parser::parse): If variants are requested, define
- parser::union_type, parser::variant, change the definition of
- semantic_type, construct $$ before running the user action instead
- of performing a default $$ = $1.
- * examples/variant.yy: New.
- Based on an example by Michiel De Wilde.

- gnulib's quotearg behavior, string_as_id in parse-gram.y no longer
- escapes trigraphs in symbol names. Thus, yytname no longer has
- trigraphs unnecessarily doubly escaped. Update test case output.
- Extend test case to be sure Bison's own error messages will no longer
- have trigraphs in symbol names unnecessarily escaped once.

- problems that are induced by this problem.
- * src/scan-skel.l: Recognize @` digraph outside of directive arguments
- instead of just in them. Recognize @\n in both places. Both expand to
- the empty string. Needed by b4_cat.

- defined. Reported by Christian Burger at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00031.html>.
- * THANKS: Add Christian Burger.
-
- * ChangeLog: For changes in doc/bison.texinfo, consistently reference
- node names: say "Decl Summary" not "Bison Declaration Summary".
-
-2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
- determine whether this function has already complained about an invalid
- value for a %define boolean variable, don't check whether Bison has
- ever examined the value. As written, the check was a tautology.
- Instead, record and check for this complaint using a separate muscle.

- (Push Parsing: Memory Leak for Early Deletion): New test case.
-
-2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Improve handling of multiple S/R conflicts in the same state and of S/R
- conflicts involving multiple reductions.
- * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
- set for a state here or Bison will abort if it is reassigned on a
- later conflicted reduction in the same state.
- Similarly, don't finalize and assign the solved conflicts report here
- or it will be lost if it is reassigned on a later conflicted reduction
- in the same state.
- (set_conflicts): Instead, assign them both here after all S/R conflicts
- in the state have been fully examined.
- * src/print.c (shift_set): Rename to...
- (no_reduce_set): ... this.
- (print_reductions): Update for rename, and add %nonassoc error action
- tokens to no_reduce_set so that, when printing the first remaining
- reduction on an error action token, the reduction is enclosed in
- brackets.
- (print_results): Update for rename.
- * tests/conflicts.at (Solved conflicts report for multiple reductions
- in a state): New test case.
- (%nonassoc error actions for multiple reductions in a state): New test

- * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
- uniwidth.
-
-2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * bootstrap (slurp): Create target directories that don't exist.
- Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
-
-2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * LR0.c (new_itemsets): Fix wording in comments: say item index rather
- than item number.
- * closure.c (closure): Likewise.
- * state.h (reductions): Comment sorting of rules.
- (state): Comment sorting of items.
-
-2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix C++ test cases after recent Gnulib changes. Discussed starting at
- <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
- * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
- definition in order to avoid Gnulib headers since we don't use config.h
- here.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
- rather than AT_DATA so that config.h is included.
-
-2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
- instead of fprintf. Guard these functions with #if YYDEBUG instead of
- #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
- and so that YYFPRINTF is guaranteed to be defined here.
-
-2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
- with...

- * src/muscle_tab.h: Likewise.
-
- Improve some comments in parser table construction.
- * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.

- * src/closure.c (closure): Explain sorting of core and itemset, which
- is required for this function to behave correctly.
- * src/closure.h (closure): Mention sorting.
-
-2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/lalr.c (state_lookahead_tokens_count): For code readability,
- move the check for disabled transitions to an aver since conflict
- resolution hasn't happened yet.
-
- * src/lalr.c (state_lookahead_tokens_count): Remove the check that
- labels a state as inconsistent just because it has error transitions.
- The original form of this check appeared in revision 1.1 of lalr.c,
- which was committed on 1991-12-21. Now (at least), changing the
- consistency label on such a state appears to have no useful effect in
- any of the places it is examined, which I enumerate below. The key
- point to understanding each item in this enumeration is that a state
- with an error transition is labelled consistent in the first place only
- if it has no rules, so the check cannot matter for states that have
- rules. (1) Labelling a state as inconsistent will cause set_conflicts
- to try to identify its conflicts, and a state must have *rules* to have
- conflicts. (2) Labelling a state as inconsistent will affect how
- action_row sets the default *rule* for the state. (3) Labelling a
- state as inconsistent will cause build_relations to add lookback edges
- to *rules* in that state.
- * src/state.h (struct state): Word the comment for member consistent
- more carefully.
-

- Undo my 2007-02-07 change, switching back to the c-strcase module
- introduced in the 2007-02-03 change. Bruno Haible reported that

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

-
- Adjust to recent gnulib changes.
- * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.

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

- * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
- (Bison Options): Document in --skeleton entry.
- * src/output.c (output_skeleton): Use strncpy rather than strcpy since
- full_skeleton can't necessarily hold all of pkgdatadir.
- If the specified skeleton file name contains a `/', don't prepend
- pkgdatadir.
- * src/parse-gram.y (prologue_declaration): If the specified skeleton
- file name contains a `/', prepend the grammar file directory.

-
- Clean up %define and %code implementation in M4 some. Most
- importantly, rename all related macros to be in the b4_percent_define
- and b4_percent_code namespaces. Also, complete support for `.' in
- %define variable names and %code qualifiers.
- * data/bison.m4 (b4_check_user_names): Check for special
- "SKELETON-NAMESPACE(name)" macros instead of using two nested
- m4_foreach loops.
- (b4_get_percent_define, b4_get_percent_code): Rename to...
- (b4_percent_define_get, b4_percent_code_get): ... these.
- Extend documentation with examples.
- For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
- b4_percent_define_skeleton_variables and
- b4_percent_code_skeleton_qualifiers.
- Expect any value for the %define variable `foo' to be stored in the
- macro named `b4_percent_define(foo)'; expect any %code blocks for the
- qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
- expect any unqualified %code blocks to be stored in a macro named
- `b4_percent_code_unqualified'.
- Use m4_indir so that %define variable names and %code qualifiers can
- contain `.', which is allowed by the grammar parser.
- (b4_percent_define_default): New macro to set a default value for a
- %define variable.
- (m4_wrap): Update wrapped code, and fix some underquoting.
- (b4_check_user_names_wrap): Update and define outside the m4_wrap.
- Expect grammar uses of %define variables and %code qualifiers to be
- defined in b4_percent_define_user_variables and
- b4_percent_code_user_qualifiers.
- * data/c++.m4: Use b4_percent_define_default rather than
- m4_define_default. Fix some underquoting. Skeleton usage of %define
- variable define_location_comparison now implies skeleton usage of
- %define variable filename_type.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Update macro names.
- * src/parse-gram.y (prologue_declaration, grammar_declaration): Update
- muscle names.
-
-2007-01-14 Juan Manuel Guerrero <juan.guerrero@gmx.de>
-
- DJGPP specific issues.

- default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
- run parsers in all tests so that Valgrind is invoked during
- maintainer-check-valgrind.
- (Duplicate representation of merged trees): Free all semantic values.
- (Duplicated user destructor for lookahead): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a
- command-line prefix.
- * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is
- ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't
- miss Valgrind messages.
- (Exploding the Stack Size with Malloc): Likewise.
-
-2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be
- locals. Reported by Juan Manuel Guerrero at

-
- Simplify union and prologue handling, and escape union and lex/parse
- params with digraphs.
- * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
- values to the empty string since these are no longer guaranteed
- initialized by the front-end.
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
- braces around b4_user_stype since this is no longer done by the
- front-end.
- * src/files.c, src/files.h (pre_prologue_obstack,
- post_prologue_obstack): Remove.
- * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
- comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped
- with digraphs. This fixes lex params and parse params.
- * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
- * src/output.c (prepare): Remove muscle insertion of the prologues.
- (output): Remove freeing of pre_prologue_obstack and
- post_prologue_obstack.
- * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
- than prologue_augment for prologue parsing so you don't need prologue
- obstacks.
- (grammar_declaration): For %union RHS, use `braceless' instead of
- "{...}" so that braces are already stripped and code is escaped with
- digraphs.
- * src/reader.c (prologue_augment): Remove.
- (reader): Remove initialization of pre_prologue_obstack and
- post_prologue_obstack.
- * src/reader.h (prologue_augment): Remove.
-
- * data/c.m4: Remove stray parenthesis.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove quotes from variables names in %define directives and from
- qualifiers in %code directives, and restrict the characters that are
- allowed in them to M4-friendly ones. For %define, continue to support
- the quoted form as a deprecated feature. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>.
- * NEWS (2.3a+): Add entry for the change to %define. Update entry for
- %code.
- * doc/bison.texinfo (Prologue Alternatives): Update.
- (Decl Summary): In %defines entry, update mention of `%code requires'
- and `%code provides'.
- (C++ Location Values): Update %define uses.
- (Calc++ Parser Interface): Likewise.
- (Calc++ Parser): Likewise, and update `%code requires' uses.
- (Table of Symbols): Update %code documentation.
- * src/parse-gram.y (prologue_declaration): For %define variables, use
- `variable' instead of `STRING'.
- (grammar_declaration): For %code qualifiers, use `ID' instead of

-
- * src/parse-gram.y (prologue_declaration): Use MUSCLE_INSERT_STRING

- characters are replaced with digraphs.
- * tests/input.at (%define errors): Extend to check weird values.
-
-2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Instead of having skeletons declare all valid %define variables and
- %code qualifiers, provide macros that retrieve the associated values
- and build these lists automatically. Thus Bison will now warn when a
- variable or qualifier is not used by the skeleton in the current
- invocation regardless of whether it might sometimes be used by that
- skeleton in other invocations. Also, move all %define value macros to
- the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
- form, which is replaced by %code.
- * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
- (b4_check_user_names): ... this, and change the series of valid name
- arguments to a single list argument for names used in the skeleton
- similar to the existing list argument for names used in the grammar.
- Warn instead of complaining.
- (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
- values and %code code, to format %code code properly, and to build
- lists of all %define variables and %code qualifiers used in the
- skeleton: b4_skeleton_percent_define_variables and
- b4_skeleton_percent_code_qualifiers.
- (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
- Remove, and...
- (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
- the skeleton names lists can finish building first. In place of
- b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
- expect the lists b4_user_percent_define_variables and
- b4_user_percent_code_qualifiers.
- * data/c++.m4: Where setting default values for b4_parser_class_name,
- b4_location_type, b4_filename_type, b4_namespace, and
- b4_define_location_comparison, update their names to the
- b4_percent_define_ namespace.
- * data/glr.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
- (b4_parser_class_name, b4_namespace): Define these using
- b4_get_percent_define for parser_class_name and namespace.
- * data/location.cc: Use b4_get_percent_define.
- * data/push.c: Don't use b4_check_percent_define_variables and
- b4_check_percent_code_qualifiers. Use b4_get_percent_code.
- * data/yacc.c: Likewise, and don't call m4_exit in
- b4_use_push_for_pull_if or m4_wrap code will never execute.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
- Rename to...
- (muscle_grow_user_name_list): ... this for consistency with the
- terminology used in bison.m4.
- * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
- %define variable names, and rename muscle used_percent_define_variables
- to user_percent_define_variables.
- (grammar_declaration): Rename muscle used_percent_code_qualifiers to
- user_percent_code_qualifiers.
- (content): Remove.
- (content.opt): Replace content RHS with STRING RHS so %define "NAME"
- {CODE} form is no longer accepted.
- * tests/input.at (Reject bad %code qualifiers): Rename to...
- (Reject unused %code qualifiers): ... this, and update test output.
- (%define error): Update test output.
-
-2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Check for unrecognized %define variables similar to checking for
- unrecognized %code qualifiers. Check for redefined %define variables.
- * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
- generalizes...
- (b4_check_percent_code_qualifiers): ... this, which now wraps it.
- (b4_check_percent_define_variables): New, also wraps it.
- * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
- variables using b4_check_percent_define_variables.
- * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
- all those exercised in the test suite and all those listed in the
- `Default values' section of c++.m4. Are there others?
- * data/push.c, data/yacc.c: Declare no valid %define variables.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
- similar to muscle_find, but it works even when the muscle stores a
- const value.
- (muscle_grow_used_name_list): New function for constructing the used
- name list muscles that b4_check_for_unrecognized_names requires.
- * src/parse-gram.y (prologue_declaration): Warn if a variable is
- %define'd more than once. Define the b4_used_percent_define_variables
- muscle with muscle_grow_used_name_list.
- (grammar_declaration): Abbreviate %code code with
- muscle_grow_used_name_list.
- * tests/input.at (%define errors): New.
-
-2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Provide warn_at, complain_at, and fatal_at function callbacks to the
- skeletons, and use this for %code qualifier complaints.
- * data/bison.m4 (b4_error_at): New, invoked by...
- (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
- the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
- @fatal_at(...@) directives.
- (b4_check_percent_code_qualifiers): Rewrite to expect locations for
- qualifiers in b4_used_percent_code_qualifiers and to use
- b4_complain_at.
- * src/location.c, src/location.h (boundary_set_from_string): New global
- function.
- * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
- function.
- * src/parse-gram.y (grammar_declaration): Add locations for qualifiers
- to b4_used_percent_code_qualifiers.
- * src/scan-skel.l (fail_for_at_directive_too_few_args): New static
- function.
- (AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
- (lineno): Rename to...
- (out_lineno): ... this so I don't misunderstand it again.
- (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
- here; these newlines are in the input but not the output file.
- (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
- (at_directive_perform): ... this new static function, and add handling
- of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
- directives.
- * tests/input.at (Reject bad %code qualifiers): Update test output with
- locations and extend.
-
- * tests/output.at (Output file name: [, Output file name: ]): Remove
- bogus comment about these tests failing.
-
-2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up b4_check_percent_code_qualifiers a little.
- * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
- in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
- documentation and add examples.
- * src/parse-gram.y (grammar_declaration): Double-M4-quote those
- qualifiers here.
-
-2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
- unreliable -- especially when they're hidden inside another macro.
- * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
- data/c.m4: Remove m4_divert(-1).
- * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
- data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
- m4_divert_push(0) and m4_divert_pop(0).
- * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
- an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
- pushed and popped by m4sugar, should be first on the stack.
-
- Provide warn, complain, and fatal function callbacks to the skeletons.
- This provides more flexibility than m4_fatal, improves the error
- message format, and captures messages for translation. Discussed
- starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
- * data/bison.m4 (b4_error): New, invoked by...
- (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
- skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
- directives. Because these M4 macros might be called when the current
- diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
- the previous removal of uses of m4_divert, which caused trouble.
- (b4_check_percent_code_qualifiers): Use b4_complain instead of
- m4_fatal to report unrecognized %code qualifiers.
- * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
- push parser requests.
- * data/glr.c: Use b4_complain instead of m4_fatal to report
- non-deterministic push parser requests.
- Update @output usage to @output(...@) form.
- * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to
- report missing %defines. Update @output usage to @output(...@) form.
- * data/location.cc, data/push.c, data/yacc.c: Update @output usage to
- @output(...@) form.
- * src/main.c (main): Invoke skel_scanner_free.
- * src/scan-skel.h (skel_scanner_free): Prototype new function.
- * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the
- obstack_for_string from flex-scanner.h.
- (YY_DECL): Use to declare skel_lex static.
- (decode_at_digraphs): Remove; now handled in the new
- SC_AT_DIRECTIVE_ARG start condition.
- (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
- functions.
- (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
- at_directive_argv): New static globals.
- (INITIAL): Use fail_for_invalid_at.
- Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
- recognize the start of a generalized `@directive(...@)' form and
- start...
- (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
- directive args (using the new obstack_for_string), to decode the
- contained @ diagraphs, and to perform the directive. It recognizes
- @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
- @output(...@).
- (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
- SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
- `@,'.
- (scan_skel): Initialize obstack_for_string on the first call.
- (skel_scanner_free): New function to free obstack_for_string.
- * tests/input.at (Reject bad %code qualifiers): Update test output.
-

- %code-top. Rewrite %code entry, and add a %code "QUALIFIER" entry.
- * data/bison.m4 (b4_user_provides, b4_user_requires): Remove as these
- are replaced by b4_percent_code_provides and b4_percent_code_requires,
- which are skeleton-specific.
- (b4_check_percent_code_qualifiers): New. A skeleton can use this to
- declare what %code qualifiers it supports and to complain if any other
- qualifiers were used in the grammar.
- * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])
- and b4_user_code([b4_percent_code_provides]) in place of
- b4_user_requires and b4_user_provides.
- * data/glr.c, data/lalr1.cc, data/push.c, data/yacc.c: Likewise.
- Add b4_user_code([b4_percent_code_top]) and
- b4_user_code([b4_percent_code]).
- Invoke b4_check_percent_code_qualifiers.
- * src/parse-gram.y (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- (grammar_declaration): Remove RHS's for %code-top, %provides, and
- %requires. Rewrite the %code RHS as the unqualified form defining the
- muscle b4_percent_code. Add another RHS for the qualified %code form,
- which defines muscles of the form b4_percent_code_QUALIFIER and the
- b4_used_percent_code_qualifiers muscle.
- * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
- PERCENT_REQUIRES): Remove.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use
- %code "requires" and %code "provides".

- semantic_type_printer_set, default_tagged_destructor_set,
- default_tagless_destructor_set, default_tagged_printer_set,
- default_tagless_printer_set): Use code_props in arguments and return
- types in place of char const * and location.
- (symbol_destructor_location_get, symbol_printer_location_get): Remove
- since the locations are now contained in the return of

-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Use the new code_props interface in parse-gram.y.
- * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
- Update all uses of translate_* functions to use the new code_props
- interface and to use gram_scanner_last_string_free and
- code_scanner_last_string_free where possible.
- (grammar_declaration): symbol_list_destructor_set and
- symbol_list_printer_set now perform the translation, so don't do it
- here. Use gram_scanner_last_string_free where possible.
- * src/scan-code.h, src/scan-code.l (translate_symbol_action,
- translate_code): Remove, no longer used.
- * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
- symbol_list_printer_set): Perform code translation here rather than
- depending on the caller to do so.
-
- * src/symlist.h (struct symbol_list): Correct some documentation typos.
- * src/scan-gram.h (gram_last_string): Remove declaration.
- * src/scan-gram.l (last_string): Declare it static.
-
-2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate code properties and related functionality for the various
- destructors, printers, and actions into a code_props structure and
- interface. This patch merely implements code_props in scan-code.h and
- scan-code.l. Future patches will rewrite other modules to use it.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
- * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
- consistently initialize const structs that have an empty location
- field.
- * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
- to ensure consistency.
- * src/scan-code.h (code_props): New structure.
- (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
- function, macro, and const global variable for initializing a
- code_props with no code.
- (code_props_plain_init, code_props_symbol_action_init,
- code_props_rule_action_init, code_props_translate_code): The rest of
- the new code_props functional interface. Among other things, the init
- functions set the code_props kind field so that
- code_props_translate_code will know whether to behave like
- translate_symbol_action, translate_rule_action, or translate_code.
- These old translate functions must remain until all other modules are
- updated to use the new code_props interface.
- (code_scanner_last_string_free): New function similar to
- gram_scanner_last_string_free.
- (code_scanner_free): Add documentation.
- * src/scan-code.l: Implement the new interface.
- (code_lex): Make it static, add a code_props* argument, and remove the
- rule argument.
- (last_string): New static global similar to the one in scan-gram.l.
- (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
- instead of rule.
- (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
- code_props since Bison may one day use this information for destructors
- and printers.
- (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
- (handle_action_dollar): Use symbol_list_n_get and set used flag
- directly since symbol_list_n_used_set is removed.
- (translate_action): Add a code_props* argument and remove the rule,
- action, and location arguments. Pass the code_props* on to code_lex.
- (translate_rule_action, translate_symbol_action, translate_code):
- Rewrite as wrappers around the new code_props interface.
- * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
- it would eventually need to break the encapsulation of code_props.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * etc/.cvsignore: New.
-
-2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Add maintainer-push-check to run maintainer-check using push parsing in
- place of pull parsing where available.
- * Makefile.am (maintainer-push-check): New.
- * data/bison.m4 (b4_use_push_for_pull_if): New.
- * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
- appropriately based on their existing values.
- (yypush_parse): Don't print push-parser-specific diagnostics if push
- parsing is being used in place of pull parsing.
- * data/yacc.c: If push parsing should replace pull parsing, redirect to
- push.c.
- * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
- variable, and insert b4_use_push_for_pull_flag into muscles.
- * tests/Makefile.am (maintainer-push-check): New.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
- (whether successful or failed) so that yypush_parse can be invoked
- again to start a new parse using the same yypstate.
- * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
- check multiple yypull_parse invocations on the same yypstate. For pull
- mode, extend to check multiple yyparse invocations.
- (Exploding the Stack Size with Alloca): Extend to try with
- %push-pull-parser.
- (Exploding the Stack Size with Malloc): Likewise.
-
- * tests/calc.at (Simple LALR Calculator): Don't specify
- %skeleton "push.c" since %push-pull-parser implies that now.
- * tests/headers.at (export YYLTYPE): Don't check for the push
- declarations. Otherwise, this test case can't be used to see if push
- mode can truly emulate pull mode.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
- (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
- AT_YACC_IF, which now includes the case of push mode since %skeleton
- need not be used for push mode. This will be more intuitive once
- push.c is renamed to yacc.c.
-
-2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, convert yyparse from a macro to a function, invoke yylex
- instead of passing a yylexp argument to yypull_parse, and don't
- generate yypull_parse or yyparse unless %push-pull-parser is declared.
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
- * data/bison.m4 (b4_pull_if): New.
- * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
- * data/push.c: Improve M4 quoting a little.
- (b4_generate_macro_args, b4_parenthesize): Remove.
- (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
- any time a pull parser is requested.
- Don't #define this as a wrapper around yypull_parse. Instead, when
- both push and pull are requested, make it a function that does that
- same thing.
- (yypull_parse): If there's a b4_prefix, #define this to
- b4_prefix[pull_parse] when both push and pull are requested.
- Don't define this as a function unless both push and pull are
- requested.
- Remove the yylexp argument and hard-code yylex invocation instead.
- * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
- %push-parser.
- * src/getargs.c (pull_parser): New global initialized to true.
- * getargs.h (pull_parser): extern it.
- * src/output.c (prepare): Insert pull_flag muscle.
- * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
- (prologue_declaration): Set both push_parser and pull_parser = true for
- %push-pull-parser. Set push_parser = true and pull_parser = false for
- %push-parser.
- * src/scan-gram.l: Don't accept %push_parser as an alternative to
- %push-parser since there's no backward-compatibility concern here.
- Scan %push-pull-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
- instead of %push-parser.
- * tests/headers.at (export YYLTYPE): Make yylex static, and don't
- prototype it in the module that calls yyparse.
- * tests/input.at (Torturing the Scanner): Likewise.
- * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
-
-2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Update etc/bench.pl. Optimize push mode a little (the yyn change
- deserves most of the credit).
- * Makefile.am (SUBDIRS): Add etc subdirectory.
- * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
- * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
- yytoken, yyval, and yyloc declarations to...
- (yyparse or yypush_parse): ... here to improve performance. For
- yypush_parse invocations after the first, be sure to assign yyn its old
- value again.
- (yypstate_new): Don't bother initializing the yyresult field since the
- initial value isn't used.
- (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
- remove the #define that, in push mode, set it to yyps->NAME.
- * etc/Makefile.am: New.
- * etc/bench.pl: Remove and build it instead from...
- * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
- "tests/bison" from the build directory by default rather than just
- invoking "bison" from $PATH.
- (calc_grammar): Update push parser code: don't declare yylval globally,
- don't define yyparse_wrapper, and don't #define yyparse.
- (bench_grammar): Update to check all working combinations of yacc.c,
- push.c, impure, pure, pull, and push.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For push mode, add pull wrappers around yypush_parse.
- * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
- (yypull_parse): New function wrapping yypush_parse.
- (yyparse): New #define wrapping yypull_parse.
- * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
- is declared.
- * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
- prototype yylex in the module that calls yyparse, and don't prototype
- yyparse there. Otherwise, the yyparse expansion won't compile.
- * tests/input.at (Torturing the Scanner): Likewise.
-
-2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable push parsers to operate in impure mode. Thus, %push-parser no
- longer implies %pure-parser. The point of this change is to move
- towards being able to test the push parser code by running the entire
- test suite as if %push-parser had been declared.
- * data/push.c (yypush_parse): For impure mode, remove the
- yypushed_char, yypushed_val, and yypushed_loc arguments.
- Instead, declare these as local variables initialized to the global
- yychar, yylval, and yylloc.
- For the first yypush_parse invocation only, restore the initial values
- of these global variables when it's time to read a token since they
- have been overwritten.
- * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
- %push-parser.
- * tests/calc.at (Simple LALR(1) Calculator): Always declare
- %pure-parser along with %push-parser since this test case was designed
- for pure push parsers.
- * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
- (AT_YACC_OR_PUSH_IF): New.
- (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
- add a note that it's still wrong for some cases (as it has been for a
- while).
- (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
- %push-parser no longer implies %pure-parser.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Remove some unnecessary differences between the pull parser code and
- the push parser code. This patch enables yynerrs in push mode.
- * data/push.c: Reformat M4 a little.
- (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
- (b4_declare_scanner_communication_variables): Don't omit yynerrs just
- because push mode is on. Instead, if pure mode is on, move yynerrs
- to...
- (b4_declare_parser_state_variables): ... here.
- (yynerrs, yyerror_range): For push mode, #define each NAME in this list
- to yyps->NAME so it can be used in yypush_parse.
- (yypush_parse): Don't omit uses of yynerrs in push mode.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug such that the first pushed token's value and location are
- sometimes overwritten (sometimes by %initial-action) before being used.
- * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
- yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
- For the first yypush_parse invocation, initialize yychar to YYEMPTY to
- more closely mimic the pull parser logic.
- Don't copy the pushed token to yychar, yylval, and yylloc until it's
- time to read a token, which is after any initialization of yylval and
- yylloc.
- (gottoken): Rename label to...
- (yyread_pushed_token): ... for clarity and to avoid infringing on the
- user namespace.
-
-2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Rearrange initialization of the parser state variables so that the
- skeleton doesn't have to have a copy for pull mode and another for push
- mode. This patch also fixes at least a bug such that yylloc was not
- initialized (with b4_location_initial_line and
- b4_location_initial_column) upon calling yypush_parse. However, that
- initialization now overwrites the first token's location;
- %initial-action assigning @$ already did the same thing, and both bugs
- will be fixed in a later patch.
- * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
- (b4_declare_parser_state_variables): Remove initialization of yytoken,
- yyss, yyvs, yyls, and yystacksize.
- (yypstate_new): Remove initialization of some yypstate fields: yystate,
- yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
- yylsp.
- (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
- yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yypush_parse, don't print the
- "Starting parse" diagnostic for invocations after the first.
- Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
- yypush_parse, only do it for the first invocation.
- Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
- initialization to occur in yypush_parse but only on the first
- invocation.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c: Add CPP guards around push parser declarations in both
- the header and the code file.
- In the code file, move the push parser declarations to the same place
- they appear in the header file.
- Clean up the M4 some, especially the inconsistent underquoting in
- some b4_c_function_def and b4_c_function_decl uses.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Encapsulate the push parser state variables into an M4 macro so the
- push skeleton doesn't have to list them again for pull mode's yyparse.
- For push mode, remove yypush_parse's local equivalents of these
- variables to eliminate unnecessary copying between the two sets at
- run-time. This patch also fixes at least a bug related to multiple
- %initial-action invocations in push mode.
- * data/push.c (b4_declare_parser_variables): Rename to...
- (b4_declare_scanner_communication_variables): ... this for clarity and
- update both uses.
- (b4_declare_yyparse_variables): Remove and move its contents to the one
- spot where it was invoked.
- (b4_declare_parser_state_variables): New macro containing the parser
- state variables required by push mode.
- (struct yypstate): Replace all fields but yynew with
- b4_declare_parser_state_variables.
- (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
- yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
- each NAME in this list to yyps->NAME so it can be used in yypush_parse.
- (yyparse or yypush_parse): For yyparse in pull mode, replace local
- parser state variable declarations with
- b4_declare_parser_state_variables.
- Don't initialize parser state variables when calling yypush_parse since
- yypstate_new already does that.
- Invoke the user's initial action only upon the first yypush_parse
- invocation.
- Remove all code that copies between the local parser state variables
- and the yypstate.
-
-2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
- prevent a name collision in a future patch where these names will
- sometimes be #define'd.
- (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
- since it no longer has the same name as the existing argument.
- (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
-
-2006-12-19 Paolo Bonzini <bonzini@gnu.org>
- and Joel E. Denny <jdenny@ces.clemson.edu>
-
- * doc/bison.texinfo (Decl Summary): In the %language entry, mention
- that the argument is case-insensitive, and there's no `=' here.
- For the %skeleton entry, mention that %language is better.
- (Bison Options): Likewise for --language and --skeleton. Move the
- --skeleton entry so that the `Tuning the parser' section is sorted
- alphabetically on long options.
- (C++ Bison Interface): Don't use the word skeleton. Don't explain the
- %language directive in detail here; cross-reference the %language
- documentation instead.
- (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
- `%require "2.3b"' so that the example is always up-to-date.
- (Table of Symbols): Add entries for %language and %skeleton.
- * examples/extexi (normalize): Instead of replacing every %require
- argument with the current Bison version, just substitute for
- `@value{VERSION}'. This guarantees that we're testing what actually
- appears in the documentation.
- * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
- rather than `@VERSION@'.

-
-2006-12-13 Paul Eggert <eggert@cs.ucla.edu>
-
- * TODO: Add pointer to Sylvain Schmitz's work on static detection
- of potential ambiguities in GLR grammers.
-
-2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
- `bison ', use m4_index instead of m4_substr since chopping up a string
- containing M4-special characters causes problems here.
-
- Fix a couple of bugs related to special characters in user-specified
- file names, and make it easier for skeletons to compute output file
- names with the same file name prefix as Bison-computed output file
- names.
- * data/glr.cc, data/push.c, data/yacc.c: In @output, use
- b4_parser_file_name and b4_spec_defines_file instead of
- @output_parser_name@ and @output_header_name@, which are now redundant.
- * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
- b4_parser_file_name, b4_spec_defines_file, and the new
- @basename(FILENAME@) instead of @output_parser_name@ and
- @output_header_name@, which inappropriately escaped the file names as
- C string literals.
- * src/files.c (all_but_ext): Remove static qualifier.
- (compute_output_file_names): Move `free (all_but_ext)' to...
- (output_file_names_free): ... here since all_but_ext is needed later.
- * src/files.h (all_but_ext): Extern.
- * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
- exactly what MUSCLE_INSERT_STRING used to do.
- (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
- characters are escaped properly.
- * src/output.c (prepare): Define muscle file_name_all_but_ext as
- all_but_ext.
- For pkgdatadir muscle, maintain previous functionality by using
- MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
- is that b4_pkgdatadir is used inside m4_include in the skeletons, so
- digraphs would never be expanded. Hopefully no one has M4-special
- characters in his Bison installation path.
- * src/scan-skel.l: Don't parse @output_header_name@ and
- @output_parser_name@ anymore since they're now redundant.
- In @output, use decode_at_digraphs.
- Parse a new @basename command that invokes last_component.
- (decode_at_digraphs): New.
- (BASE_QPUTS): Remove unused.
- * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
- (Output file name): New tests.
-
-2006-12-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Warn about output files that are generated by the skeletons and that
- conflict with other output files.
- * data/glr.c: Don't generate the header file here when glr.cc does.
- * src/files.c (file_names, file_names_count): New static globals.
- (compute_output_file_names): Invoke output_file_name_check for files
- not generated by the skeletons and remove existing checks.
- (output_file_name_check): New function that warns about conflicting

- * src/files.h (output_file_name_check): Declare.
- * src/scan-skel.l: Invoke output_file_name_check for files generated by

- (yypstate_init, yypstate, struct yypstate, yypush_parse): ... these and
- update all uses.
- (b4_yyssa, b4_yyerror_range, yypstate_init): Rename pv to yyps.
- (yypush_parse): Rename yypvars argument to yyps and remove redundant
- local pv.

-
- * data/push.c (yypvarsinit): Change return type from void* to struct
- yypvars*. No longer cast to void* on return.
- (struct yypvars): Remove yylen since it need not be remembered between
- yypushparse invocations.
- (yypushparse): Don't copy between yylen and pv->yylen.
-
-2006-12-05 Bob Rossi <bob@brasko.net>
-
- * data/push.c (yychar_set, yylval_set, yylloc_set): Delete.
- (yypushparse): Add yynchar, yynlval, yynlloc parameters.
- (b4_declare_parser_variables): Do not declare yynerrs for push mode.
- (struct yypvars): Remove b4_declare_parser_variables.
- (yypvarsinit): Remove init code for removed variables.
- (global scope): Do not declare b4_declare_parser_variables if
- push or pure mode.
- (yypushparse): Add b4_declare_parser_variables.
- Init new local variables, and remove init code for removed
- yypvars variables.
- (yyparse): Delete.
- * tests/calc.at (_AT_DATA_CALC_Y): Call yypushparse for push mode
- and yyparse for other modes.
- (AT_CHECK_CALC_LALR): Added '%skeleton "push.c"' for push tests.
- * tests/local.at (AT_PUSH_IF, AT_PURE_OR_PUSH_IF): Added.
- (AT_YYERROR_SEES_LOC_IF): push-parser makes this false.
- (AT_PURE_LEX_IF): True if pure or push parser.

- Fix memory leaks in scanners generated by at least Flex 2.5.9 and
- later. Reported by Paul Eggert in
- <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00014.html>.
- * src/flex-scanner.h (yylex_destroy): Define for Flex before 2.5.9.
- * src/scan-code.l (translate_action): Don't bother invoking
- yy_delete_buffer (YY_CURRENT_BUFFER) before creating the first buffer.
- (code_scanner_free): Instead of invoking
- yy_delete_buffer (YY_CURRENT_BUFFER) directly, invoke yylex_destroy,
- which frees more.
- * src/scan-gram.l (gram_scanner_free): Likewise.
- * src/scan-skel.l (scan_skel): Likewise.
-
-2006-11-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/files.c (tr): Change return type to void.
- * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow
- has been called previously for the same key.
- (muscle_find): Return storage instead of value so that
- --enable-gcc-warnings doesn't produce warnings that the return discards
- const. aver that the value and storage are the same since storage
- could potentially be NULL when value is not.
- * tests/testsuite.at (AT_CHECK): Treat an unspecified exit value the
- same as 0.
-
-2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing
- the earlier change today), m4/intl.m4, m4/intldir.m4. This gives
- us a slightly cleaner distribution, and also works.
- * m4/.cvsignore: Add inline.m4, wint_t.m4 to accommodate recent

- (all_but_ext, all_but_tab_ext, src_extension, header_extension):
- Likewise.
- (tr): Now operates in-place. All uses changed.

- will be freed.
- * src/main.c (main): Invoke output_file_names_free, code_scanner_free
- (which previously existed but was unused), and quotearg_free.
- * src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
- * src/muscle_tab.c: Likewise.
- (muscle_entry): Make the value char const *,
- and add a new storage member that is char * and can be freed.
- (muscle_entry_free): New private function.
- (muscle_init): Use it instead of free.
- (muscle_insert, muscle_grow): Update and use new storage member.
- (muscle_code_grow): Free the string passed to muscle_grow

- * src/scan-code.h (translate_rule_action):
- (translate_symbol_action, translate_code, translate_action): Return
- `char const *' rather than `char *' since external code should not free
- these strings.
- * src/scan-code.l: Likewise.
- * src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
- which is "{...}" in the parser.
- * tests/Makefile.am (maintainer-check-valgrind): Set
- VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
- Valgrind.
- * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
- complain.
- * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
- expecting a non-zero exit status sets --leak-check=summary and
- --show-reachable=no for Valgrind. Bison unabashedly leaks memory in
- this case, and we don't want to hear about it.
-
-2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap (runtime-po/Makevars): Derive from po/Makevars

-
- Warn about unset midrule $$ if the corresponding $n is used.
- * src/reader.c (symbol_should_be_used): Check midrule parent rule for
- $n usage.
- (packgram): Before invoking grammar_rule_check on any rule, make sure
- all actions have already been scanned in order to set `used' flags.
- Otherwise, checking that a midrule's $$ is set will not always work
- properly because the midrule check must forward-reference the midrule's

-
-2006-10-12 Paul Eggert <eggert@cs.ucla.edu>

- and try to make such failures easier to catch in the future.
- * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
- that's now the caller's responsibility.

-
- * bootstrap (symlink_to_gnulib): New function.
- (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
- to copies-of-gnulib.
- (cp_mark_as_generated, slurp, gnulib_files):
- Avoid making a copy if it's the same as the old version.
- (gnulib_files): Add support for this variable (used by Bison).
-
-2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/getargs.c (usage): Rework to use conventions similar to
- coreutils, to make translation a bit easier and the code a bit
- smaller. Problem reported by Tim Van Holder.
-
-2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
-
- Use some of gnulib's new modules, taken from coreutils.

- (gl_EARLY): Add.
- (AM_STDBOOL_H): Remove; gl_INIT now dows this.
- (gl_INIT): Add
- (GNULIB_AUTOCONF_SNIPPET): Remove.
- (AM_GNU_GETTEXT): Add; require formatstring macros since that's
- the pickiest.
- * lib/.cvsignore: Add inttypes_.h.

- (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
- no-longer-necessary initializations.
- (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
- * lib/subpipe.c: Include <unistd.h> unconditionally, now that we

- gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
- * src/Makefile.am (DEFS): Remove, since configmake does this for us.
- (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
- * src/system.h: Include inttypes.h unconditionally, now that we
- use the inttypes module. Don't bother to include stdint.h, since
- inttypes.h now does that for us.
- (LOCALEDIR): Remove, now that we use the configmake module.
- * src/getargs.c: Include configmake.h.
- * src/main.c: Likewise.
- * src/output.c: Likewise.
- * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,
- not from $abs_top_builddir, since config.h moved.
-
-
- Port to GCC 2.95. First two problems reported by Michael Deutschmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
-
- * src/parse-gram.y (symbol_declaration): Don't put statements
- before declarations; it's not portable to C89.
- * src/scan-code.l (handle_action_at): Likewise.
-
- * src/scan-code.l: Always initialize braces_level; the old code
- left it uninitialized and therefore had undefined behavior.
-
- Don't attempt to redefine 'assert', since it runs afoul of
- systems where standard headers (mistakenly) include <assert.h>.
- Instead, define and use our own alternative, called 'aver'.
- * src/reader.c: Don't include assert.h, since we no longer
- use assert.
- * src/scan-code.l: Likewise.
- * src/system.h (assert): Remove, replacing with....
- (aver): New function, taking a bool arg. All uses changed.
- * src/tables.c (pack_vector): Ensure that aver arg is bool,
- not merely an integer.
-
-2006-09-15 Bob Rossi <bob@brasko.net>

- list of removed lines from the traces observed.
- (AT_CHECK_CALC_LALR): Added push parser tests.
-
-2006-09-13 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Version 2.3a.
- * configure.ac (AC_INIT): Likewise.
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
- "#define YYSTYPE int" that caused "make maintainer-check" to fail
- due to header ordering dependencies. I don't know why the #define
- was there.
-
- Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
- runtime cost when YYDEBUG is not defined, and so that some tests
- that used to fail now work. Problem and initial suggestion by
- Paolo Bonzini.
- * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
- * data/glr.cc (b4_parser_class_name):
- Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
- (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
- (yydebug_) [YYDEBUG]: New member.
- (yycdebug_): Now defined only if YYDEBUG.
- * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
- (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
- (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
- if YYYDEBUG.
- (debug_stream, set_debug_stream, debug_level, set_debug_level):
- Define only if YYDEBUG.
- * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to
- set_debug_level.
- * tests/regression.at (_AT_DATA_DANCER_Y) [!YYDEBUG]: Likewise.
- * tests/calc.at (AT_CHECK_CALC_GLR_CC): Uncomment calls to
- AT_CHECK_CALC_GLR_CC that are working now.
-
-2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
- We don't need them in glr.cc, and glr.c defines them.
- Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
- assumes that defining it to anything is the same as defining
- it to 1. Problem reported by Paolo Bonzini.
-
-2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
-
- * data/c.m4 (b4_null, b4_case): Define.
- * src/output.c (prepare_symbols): Use b4_null.
- (user_actions_output): Use b4_case.
-
-2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (b4_shared_declarations): Put start-header first,
- before any #includes that we generate, so that feature-test
- macros work. Problem reported by Michael Deutschmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00004.html>.
- * data/lalr1.cc: Likewise.
- * doc/bison.texinfo (Prologue): Document that feature-test macros
- should be defined before any Bison declarations.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
- that depend on location.hh after, not before, Bison decls, since
- we now include location.hh after the first user prologue.
-
- * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
- Sander Brandenburg in
- <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00002.html>.
- Also, fix minor white space and comment issues.
- (Prologue): Mention that it's better to define feature-test macros
- before Bison declarations. Problem reported by Michael Deutschmann.
-
- * README-cvs: Fix typo: "&" should be "&&". Problem reported
- by Jim Meyering.
- * m4/.cvsignore: Add argmatch.m4. Remove obstack.m4, strerror_r.m4.
- This adjusts to recent gnulib changes.
-
-2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Finish implementation of per-type %destructor/%printer. Discussed
- starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.
- * NEWS (2.3+): Add a description of this feature to the default
- %destructor/%printer description.
- * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
- * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
- Invoke semantic_type_destructor_set or semantic_type_printer_set when a
- list node contains a semantic type.
- * src/symtab.c, src/symtab.h: Extend with a table that associates
- semantic types with their %destructor's and %printer's.
- (semantic_type_from_uniqstr, semantic_type_get,
- semantic_type_destructor_set, semantic_type_printer_set): New functions
- composing the public interface of that table.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): If there's no
- per-symbol %destructor/%printer, look up the per-type before trying
- the default.
- * tests/actions.at (Per-type %printer and %destructor): New test case.
- * tests/input.at (Default %printer and %destructor redeclared):
- Extend to check that multiple occurrences of %symbol-default in a
- single %destructor/%printer declaration is an error.
- (Per-type %printer and %destructor redeclared, Unused values with
- per-type %destructor): New test cases.
-
-2006-09-04 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Require default %destructor/%printer to be declared using
- %symbol-default instead of an empty symbol list, and start working on
- new per-type %destructor/%printer. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-09/msg00007.html>.
- * NEWS (2.3+): Add %symbol-default to example.
- * bison.texinfo (Freeing Discarded Symbols): Likewise.
- (Table of Symbols): Add entry for %symbol-default.
- * src/parse-gram.y (PERCENT_SYMBOL_DEFAULT): New token.
- (generic_symlist, generic_symlist_item): New nonterminals for creating
- a list in which each item is a symbol, semantic type, or
- %symbol-default.
- (grammar_declaration): Use generic_symlist in %destructor and %printer
- declarations instead of symbols.1 or an empty list.
- (symbol_declaration, precedence_declaration, symbols.1): Update actions
- for changes to symbol_list.
- * src/reader.c: Update for changes to symbol_list.
- * src/scan-code.l: Likewise.
- * src/scan-gram.l: Scan new PERCENT_SYMBOL_DEFAULT token.
- * src/symlist.c, src/symlist.h: Extend such that a list node may
- represent a semantic type or a %symbol-default in addition to just an
- ordinary symbol. Add switched functions for setting %destructor's and
- %printer's.
- * tests/actions.at, tests/input.at: Add %symbol-default to all default
- %destructor/%printer declarations.
-
-2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Whether the default %destructor/%printer applies to a particular symbol
- isn't a question of whether the user *declares* that symbol (in %token,
- for example). It's a question of whether the user by any means
- *defines* the symbol at all (by simply using a char token, for
- example). $end is defined by Bison whereas any other token with token
- number 0 is defined by the user. The error token is always defined by
- Bison regardless of whether the user declares it with %token, but we
- may one day let the user define error as a nonterminal instead.
- * NEWS (2.3+): Say "user-defined" instead of "user-declared".
- * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
- the meaning of "user-defined".
- * tests/actions.at (Default %printer and %destructor for user-declared
- end token): Rename to...
- (Default %printer and %destructor for user-defined end token): ...
- this.
-
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
- computation of whether to apply the default, don't maintain a list of
- every Bison-defined symbol. Instead, just check for a first character
- of '$', which a user symbol cannot have, and check for the error token.
-
-2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't apply the default %destructor or %printer to the error token,
- $undefined, or $accept. This change fits the general rule that the
- default %destructor and %printer are only for user-declared symbols,
- and it solves several difficulties that are described in the new test
- cases listed below.
- * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
- * tests/actions.at (Default %printer and %destructor are not for error
- or $undefined, Default %printer and %destructor are not for $accept):
- New test cases.
-
-2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Allow %start after the first rule.
- * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
- when parsing the first rule.
- (check_and_convert_grammar): Search for it here after all grammar
- declarations have been parsed. Skip midrules, which have dummy LHS
- nonterminals.
- * src/symtab.c (symbol_is_dummy): New function.
- * src/symtab.h (symbol_is_dummy): Declare it.
- * tests/input.at (%start after first rule): New test.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Redo some of the previous commit: add back the ability to use
- non-aliased/undeclared string literals since it might be useful to
- those declaring %token-table.
- * src/reader.c (check_and_convert_grammar): Undo changes in previous
- commit: don't worry about complaints from symbols_pack.
- * src/symtab.c (symbol_new, symbol_class_set,
- symbol_check_alias_consistency): Undo changes in previous commit: count
- each string literal as a new symbol and token, assign it a symbol
- number, and don't complain about non-aliased string literals.
- (symbols_pack): Since symbol_make_alias still does not decrement symbol
- and token counts but does still set aliased tokens to the same number,
- symbol_pack_processor now leaves empty slots in the symbols array.
- Remove those slots.
- * tests/regression.at (Undeclared string literal): Remove test case
- added in previous commit since non-aliased string literals are allowed
- again.
- (Characters Escapes, Web2c Actions): Undo changes in previous commit:
- remove unnecessary string literal declarations.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't allow an undeclared string literal, but allow a string literal to
- be used before its declaration.
- * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
- symbols_pack complained.
- * src/symtab.c (symbol_new): Don't count a string literal as a new
- symbol.
- (symbol_class_set): Don't count a string literal as a new token, and
- don't assign it a symbol number since symbol_make_alias does that.
- (symbol_make_alias): It's not necessary to decrement the symbol and
- token counts anymore. Don't assume that an alias declaration occurs
- before any uses of the identifier or string, and thus don't assert that
- one of them has the highest symbol number so far.
- (symbol_check_alias_consistency): Complain if there's a string literal
- that wasn't declared as an alias.
- (symbols_pack): Bail if symbol_check_alias_consistency failed since
- symbol_pack asserts that every token has been assigned a symbol number
- although undeclared string literals have not.
- * tests/regression.at (String alias declared after use, Undeclared
- string literal): New test cases.
- (Characters Escapes, Web2c Actions): Declare string literals as
- aliases.
- * tests/sets.at (Firsts): Likewise.
-
-2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In the grammar scanner, STRING_FINISH unclosed constructs and return
- them to the parser in order to improve error messages.
- * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
- SC_BRACED_CODE, SC_PROLOGUE): Implement.
- * tests/input.at (Unclosed constructs): New test case.
- * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
- seen.
-
- * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
- unused global.
-
-2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Handle string aliases for character tokens correctly.
- * src/symtab.c (symbol_user_token_number_set): If the token has an
- alias, check and set its alias's user token number instead of its own,
- which is set to indicate the alias. Previously, every occurrence of
- the character token in the grammar overwrote that alias indicator with
- the character code.
- * tests/input.at (String aliases for character tokens): New test.
-
-2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
-
-2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
- to prevent failures when building on older platforms.
- Check for autopoint failure.
- Set XGETTEXT_OPTIONS to values that check for C format strings,
- so that translators are warned about them (this also helps
- prevent core dumps).
-
- * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
- function, since it simplifies our code a bit.
-
- * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
- rather than -W, so we don't get bogus warnings about sign comparisons.
- Add -Wpointer-arith, since that warning is useful (it reports code
- that does not conform to C89 and that some compilers reject).
- * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
- since it's no longer needed.
-
-2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up scanners a bit.
- * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
- definitions so gcc won't warn when obstack_for_string is unused.
- * src/scan-code.l: config.h and system.h are already #include'd by
- scan-code-c.c, so get rid of them here.
- * src/scan-gram.l: Likewise.
- * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
- definitions rather than duplicating the rest of it.
- * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
-
-2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Suppress signed/unsigned comparison warnings for yycheck.
- * data/c.m4 (b4_safest_int_type): New macro.
- * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
- a signed int type, cast it to b4_safest_int_type first.
- * data/yacc.c: Likewise.
- (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
- also overwritten.
-
-2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
-
- * doc/bison.texinfo: Fix some typos.
-
-2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
-
- * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
- po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
-
- * bootstrap (gnulib_tool): Stop using --assume-autoconf;
- the latest gnulib does this a different way.
- (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
- translation was patched, so stop omitting it.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Enable declaration of default %printer/%destructor. Make the parser
- use these for all user-declared grammar symbols for which the user does
- not declare a specific %printer/%destructor. Thus, the parser uses it
- for token 0 if the user declares it but not if Bison generates it as
- $end. Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
- * NEWS (2.3+): Mention.
- * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
- declare a %destructor for a mid-rule's semantic value. It's just
- impossible to declare one specific to it.
- (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
- code. Describe default %destructor form.
- * src/parse-gram.y (grammar_declaration): Parse default
- %printer/%destructor declarations.
- * src/output.c (symbol_destructors_output): Use symbol_destructor_get
- and symbol_destructor_location_get rather than accessing the destructor
- and destructor_location members of struct symbol.
- (symbol_printers_output): Likewise but for %printer's.
- * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
- again.
- * src/symtab.c (default_destructor, default_destructor_location,
- default_printer, default_printer_location): New static global
- variables to record the default %destructor and %printer.
- (symbol_destructor_get, symbol_destructor_location_get,
- symbol_printer_get, symbol_printer_location_get): New functions to
- compute the appropriate %destructor and %printer for a symbol.
- (default_destructor_set, default_printer_set): New functions to set the
- default %destructor and %printer.
- * src/symtab.h: Prototype all those new functions.
- * tests/actions.at (Default %printer and %destructor): New test to
- check that the right %printer and %destructor are called, that they're
- not called for $end, and that $$ and @$ work correctly.
- (Default %printer and %destructor for user-declared end token): New
- test to check that the default %printer and %destructor are called for
- a user-declared end token.
- * tests/input.at (Default %printer and %destructor redeclared, Unused
- values with default %destructor): New tests to check related grammar
- warnings and errors.
-
-2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up handling of %destructor for the end token (token 0).
- Discussed starting at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>
- and
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
-
- Make the skeletons consistent in how they pop the end token and invoke
- its %destructor.
- * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
- state, which has token number 0, since this would invoke the
- %destructor for the end token.
- * data/lalr1.cc (yy::parser::parse): Don't check for the final state
- until after shifting the end token, or else it won't be popped.
- * data/yacc.c (yyparse): Likewise.
-
- * data/glr.c (yyparse): Clear the lookahead after shifting it even when
- it's the end token. Upon termination, destroy an unshifted lookahead
- even when it's the end token.
- * data/lalr1.cc (yy::parser::parse): Likewise.
- * data/yacc.c (yyparse): Likewise.
-
- * src/reader.c (packgram): Don't check rule 0. This suppresses unused
- value warnings for the end token when the user gives the end token a
- %destructor.
-
- * tests/actions.at (Printers and Destructors): Test all the above.
-
-2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Update to latest gnulib and gettext versions.
- * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
- Add fopen-safer.
- (gnulib_files): Add m4/warning.m4. Don't worry about files
- overwritten by autopoint.
- Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
- Suppress "id", "ms", "tr" translations for now, since gettext 0.15
- rejects them.
- Don't use autoreconf; instead, invoke autopoint etc. by hand,
- so that we can remove the intl files at a better time.
- (intl_files_to_remove): Remove aclocal.m4, since it gets
- rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
- m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
- m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
- Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
- Remove datarootdir hack; no longer needed.
- * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
- (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
- * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
- strdup.h.
- * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
- * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
-
-2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * bootstrap: Adjust to today's change to gnulib-tool by invoking
- it with --assume-autoconf='latest-stable'.
-
-2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
- least 1.4.7 and 1.4.4) by putting a #line between `typedef union
- YYSTYPE' and `{'.
- * src/muscle_tab.h (muscle_grow): Replace the header comments with
- those from muscle_tab.c since the old ones are misleading.
-
-2006-07-13 Akim Demaille <akim@epita.fr>
-
- Support %define "KEY" {VALUE}.
- * src/scan-code.h, src/scan-code.l (translate_action)
- (translate_rule_action, translate_symbol_action, translate_code):
- Return char *, not const char *.
- * src/parse-gram.y (declaration): Rename as...
- (prologue_declaration): this.
- (string_content): Remove this nonterminal, use STRING.
- (braceless, content, content.opt): New nonterminal.
- Use them.
- (%define): Now accept content.opt, i.e., accept also BRACED_CODE
- as value.
- * src/scan-gram.l (getargs.h): Don't include it.
-
-2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
- rather than a for-loop that declares a local bool variable. This
- should work around a compatibility problem with a Cray x1e C++
- compiler reported by Hung Nguyen in
- <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
- The for-loop was introduced in the 2004-11-17 change but I don't
- know why it was needed.
-
-2006-07-12 Akim Demaille <akim@epita.fr>
-
- * data/c.m4: Comment changes.
-
-2006-07-10 Akim Demaille <akim@lrde.epita.fr>
-
- * src/complain.c (error_message, ERROR_MESSAGE): New.
- To factor...
- (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
- * src/complain.h, src/complain.c (warning_issued): Remove, unused.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * NEWS: Instead of %union, you can define and use your own union type
- YYSTYPE if your grammar contains at least one <type> tag.
- Your YYSTYPE need not be a macro; it can be a typedef.
- * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
- (Union Decl, Decl Summary): Document this.
- * data/glr.c (YYSTYPE): Implement this.
- * data/glr.cc (YYSTYPE): Likewise.
- * data/lalr1.cc (YYSTYPE): Likewise.
- * data/yacc.c (YYSTYPE): Likewise.
- * src/output.c (prepare): Output tag_seen_flag.
- * src/parse-gram.y (declaration, grammar_declaration):
- Use 'union_seen' rather than 'typed' to determine whether
- %union has been seen, since grammars can now be typed without
- %union.
- (symbol_declaration, type.opt, symbol_def):
- Keep track of whether a tag has been seen.
- * src/reader.c (union_seen, tag_seen): New vars.
- (typed): remove.
- * src/reader.h (union_seen, tag_seen, typed): Likewise.
- * src/scan-code.l (untyped_var_seen): New variable.
- (handle_action_dollar): Adjust to above changes.
- (handle_action_dollar, handle_action_at):
- Improve overflow checking for outlandish numbers.
- * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
- avoid new diagnostics generated by above changes.
- * tests/regression.at (YYSTYPE typedef): Add test to check
- for type tags without %union.
-
- * src/symlist.c (symbol_list_length): Return int, not unsigned
- int, since callers expect int. This may need to get revisited
- once we have proper integer overflow checking.
-
- * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
- object is now static.
-
- * src/getargs.c (flags_argmatch): Return void, not int,
- to pacify ./configure --enable-gcc-warnings.
-
- * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
- since last_string is already defined to FLEX_PREFIX (last_string).
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- Implement --warnings/-W.
- * src/getargs.c (report_argmatch, trace_argmatch): Remove,
- replaced by...
- (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
- Adjust callers.
- * src/getargs.h, src/getargs.c (warnings, warnings_flags)
- (warnings_args, warnings_types): New.
- (getargs, short_options, long_options): Accept -W/--warnings.
- Sort the options by alphabetical order, upper case letter right
- before its lower case.
-
-2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Change %merge result type clash warnings to errors. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
- * src/reader.c (record_merge_function_type): Use complain_at.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): Update test case results.
-
-2006-07-09 Akim Demaille <akim@lrde.epita.fr>
-
- * src/getargs.h, src/getargs.c: Swap --report and --trace handling
- to be in alphabetical order.
- (trace_args): Spelling fixes.
-
-2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
- so they don't collide with user-defined macros.
- (yy_stack_print): Don't assume that yytype_int16 promotes to int;
- this was never guaranteed, and now that we're using gnulib stdint,
- which defines int_fast16_t to long int, the problem is exposed.
-
-2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_basename): Simplify a bit, since we don't
- need the full POSIX semantics (and weren't implementing them
- anyway).
-
- Adjust to Autoconf 2.60 and today's gnulib.
- * bootstrap (gnulib_modules): Add stdint.
- Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
- no longer copies it.
- (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
- since stdint needs the former and wcwidth (which is now required
- by mbswidth) needs the latter.
- Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
- work around a compatibility glitch between gettext 0.14.6 and
- Autoconf 2.60.
- * configure.ac (AC_PREREQ): Require Autoconf 2.60.
- Do not check for uintptr_t, since new stdint module does the right
- thing.
- * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
- Add stdint.h, stdint_.h, wcwidth.h.
- * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
- Add absolute-header.m4, double-slash-root.m4, longlong.m4,
- stdint.m4, wchar_t.m4, wcwidth.m4.
- * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
- usual order for ../lib/*.h files.
- (file_name_split): Use last_component, not base_name, to adjust
- to gnulib changes.
- * src/parse-gram.h: Include <strverscmp.h> in the usual order
- for ../lib/*.h files.
- (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
- Define unconditionally, since we now assume the stdint module.
- * src/scan-skel.l: Include <dirname.h>.
- (BASE_QPUTS): Use last_component, not base_name.
- * src/system.h: Include <unlocked-io.h> in the usual order
- for ../lib/*.h files. Include <stdint.h> unconditionally,
- since we now use the stdint module.
- (uintptr_t): Declare if UINTPTR_MAX is not defined, not
- HAVE_UINTPTR_T, since we now use the stdint module.
- (base_name): Remove decl, since files now include <dirname.h>
- to get the decl.
-
-2006-07-08 Akim Demaille <akim@lrde.epita.fr>
-
- * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
- New, default to 1.
- * data/yacc.c, data/glr.c, data/location.cc: Use them.
- * NEWS, doc/bison.texinfo: The initial column and line are 1 by
- default.
- * tests/calc.at: Adjust.
-
-2006-07-08 Akim Demaille <akim@lrde.epita.fr>
-
- * data/c.m4 (b4_basename): New.
- (b4_syncline): Also output the location of its invocation (from
- the skeleton).
- (b4_user_action, b4_define_user_action, b4_user_actions)
- (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
- (b4_user_stype): New.
- * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
-
-2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In the grammar file, the first column is 1 not 0 on the first line as
- on every other line.
- * src/parse-gram.y (%initial-action): Initialize @$ correctly.
- * tests/input.at (Torturing the Scanner): Update output.
-
- * src/scan-gram.l (scanner_cursor): Declare it static.
-
-2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
-
- In warnings, say "previous declaration" rather than "first
- declaration".
- * src/symtab.c (redeclaration): Do that here.
- * src/reader.c (record_merge_function_type): In the case of a result
- type clash, report the previous declaration rather than the very first
- one in the grammar file.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): Add a third declaration to check this behavior.
- * tests/input.at (Incompatible Aliases): Update output.
-
-2006-06-27 Akim Demaille <akim@epita.fr>
-
- * doc/Doxyfile.in: New.
- * doc/Makefile.am: Use it.
- * src/lalr.h, src/symtab.h: Initial doxygenation.
-
-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't miss %merge result type warnings just because the LHS types are
- declared after the %merge. This continues the effort of the previous
- patch.
- * src/reader.c (get_merge_function): Don't set the merger type yet.
- (record_merge_function_type): New function for setting the merger type
- and checking for clashes.
- (grammar_current_rule_merge_set): Set the location of the %merge for
- the current rule.
- (packgram): Invoke record_merge_function_type for each rule now that
- all symbol type declarations have been parsed.
- * src/reader.h (merger_list.type_declaration_location): New member
- storing the location of the first %merge from which the type for this
- merging function was derived.
- * src/symlist.h (symbol_list.merger_declaration_location): New member
- storing the location of a rule's %merge, if any.
- * tests/glr-regression.at (Missed %merge type warnings when LHS type is
- declared later): New test to catch the error fixed by the above patch.
-
-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Get action warnings (grammar_rule_check) right even when symbol
- declarations appear after the rules. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
- and
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
- Don't mistake the type of $$ in a midrule to be that of its parent
- rule's $$.
- * src/reader.c (grammar_current_rule_end): Don't invoke
- grammar_rule_check yet since not all symbol declarations may have been
- parsed yet.
- (grammar_midrule_action): Likewise.
- Don't record whether the midrule's $$ has been used yet since actions
- haven't been translated yet.
- Record the midrule's parent rule and its RHS index within the parent
- rule.
- (grammar_current_rule_action_append): Don't translate the action yet
- since not all symbol declarations may have been parsed yet and, thus,
- warnings about types for $$, $n, @$, and @n can't be reported yet.
- (packgram): Translate the action and invoke grammar_rule_check now that
- all symbol declarations have been parsed.
- * src/scan-code.l (handle_action_dollar): Now that this is invoked
- after parsing the entire grammar file, the symbol list here in the case
- of a midrule is actually the midrule's empty RHS, so reference its
- parent rule's RHS where necessary.
- On the other hand, now that you can already know it's a midrule, you
- aren't forced to think $$ has the same type as its parent rule's $$.
- (handle_action_at): In the case of a midrule, reference the parent rule
- where necessary.
- * src/symlist.c (symbol_list_new): Initialize new midrule-related
- members.
- (symbol_list_length): Now that this is invoked after all rules have
- been parsed, a NULL symbol (rather than a NULL symbol list node)
- terminates a rule. symbol_list_print already does this correctly.
- * src/symlist.h (symbol_list.midrule_parent_rule,
- symbol_list.midrule_parent_rhs_index): New members so that midrules can
- remember their relationships with their parents.
- * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
- fixed by the above patch.
- (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
- implementing...
- (Unused values): ... this old test case and...
- (Unused values before symbol declarations): ... this new test case.
- This one is the same as `Unused values' except that all symbol
- declarations appear after the rules in order to catch the rest of the
- errors fixed by the above patch.
-
-2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
-
- More cleanup.
- * src/reader.c (current_rule): Declare it static since it's no longer
- used outside this file.
- (grammar_current_rule_action_append): Remove redundant arguments from
- translate_rule_action invocation.
- * src/reader.h (current_rule): Remove this unused extern.
- * src/scan-code.h (translate_rule_action): Remove redundant arguments.
- * src/scan-code.l (translate_rule_action): Likewise.
-
-2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Clean up yesterday's patch.
- * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
- to...
- * src/reader.c (grammar_current_rule_action_append): ... here for
- consistency with grammar_current_rule_symbol_append.
- * tests/regression.at (Braced code in declaration in rules section):
- Make yyerror and yylex static as usual.
-
-2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Fix bug that mistakes braced code in a declaration in the rules section
- to be a rule action. Mentioned at
- <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
- * src/scan-gram.l: Move midrule action detection from the start of the
- scanning of any braced code to...
- * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
- action. For readability, use $2 and @2 rather than the equivalent
- global variables.
- * tests/regression.at (Braced code in declaration in rules section):
- New test to catch the error fixed by the above patch.
-
- Work on code readability some.
- * src/scan-code.l (current_rule): Get rid of this misleading and
- redundant declaration: it's actually extern'ed in reader.h.
- (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
- translate_action): Add a rule argument and use it instead of the global
- current_rule.
- (translate_rule_action): This already receives current_rule through an
- argument, so pass it on to translate_action instead of assigning
- current_rule to current_rule.
- (translate_symbol_action, translate_code): Pass rule = NULL to
- translate_action.
-
-2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Rename %before-definitions to %start-header and %after-definitions to
- %end-header. Don't use these declarations to separate pre-prologue
- blocks from post-prologue blocks. Add new order-independent

- Don't put the pre-prologue in the header file. For the yacc.c code
- file and the glr.c header and code files, move the pre-prologue before
- the token definitions. Add new %before-definitions and
- %after-definitions to declare code that will go in both the header file
- and code file. Discussed at
- <http://lists.gnu.org/archive/html/bison-patches/2005-12/msg00000.html>,
- <http://lists.gnu.org/archive/html/bison-patches/2006-01/msg00016.html>,

- (b4_after_definitions): New near the end of the header file.
- * data/yacc.c: Clean up some m4 quoting especially in the header file.
- (b4_token_enums_defines): In the code file, move to right before
- YYSTYPE for consistency with the header file.
- (b4_before_definitions): New right before b4_token_enums_defines in
- both the header and code file.
- (b4_after_definitions): New right after YYLTYPE and yylloc in both the
- header and code file.

- of prologues for %union dependencies.
- (Decl Summary): In %defines description, mention the effect of
- %before-definitions and %after-definitions on the header file.

-
- The Translation Project changed its way of publishing translations
- to maintainers. I haven't received any responses to my request
- for supporting the old way, or for documenting the new way. I
- have modified 'bootstrap' to use screen scraping
- (in this case, HTML scraping). This is unreliable and inelegant,
- but I don't see any better way. Yuck.
- * bootstrap (TP_URL, WGET_COMMAND): New vars.
- (get_translations): New function, which uses HTML scraping to
- deduce locations of latest translations.
- Use this function to grab both bison and bison-runtime .po files.
- Don't bother priming the pump for the runtime-po domain any more,
- as it's now translated better than bison is.
-
-2006-06-19 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l: No longer "parse" things after `%union' until

- to symbols to the parser.
- (SC_PRE_CODE, token_type): Remove.
- * src/parse-gram.y (%union): New field `character'.
- Sort tokens.
- (CHAR): New token.
- (ID, ID_COLON): Now that the scanner no longer makes them
- identifiers, adjust all uses to invoke symbol_get.
- (id_colon): New, wraps the conversion from string to symbol.
- (%union): Accept a possible union_name.
- (symbol): Now can be a char.
- * data/c.m4 (b4_union_name): Leave a default value.
- * data/glr.c, data/yacc.c: Use it.
-
-2006-06-11 Joel E. Denny <jdenny@ces.clemson.edu>
-
- For associating token numbers with token names for "yacc.c", don't use
- #define statements unless `--yacc' is specified; always use enum
- yytokentype. Most important discussions start at:

- * src/output.c (prepare): Define b4_yacc_flag.
- * tests/regression.at (Early token definitions): Test that tokens names
- are defined before the pre-prologue not just before the post-prologue.
- Remove this test case and copy to...
- (Early token definitions with --yacc): ... this to test #define's.
- (Early token definitions without --yacc): ... and this to test enums.

- Adjust all dependencies.
- Whereever actions with $ and @ are used, use translate_code.

- * src/reader.c: Include assert.h, scan-gram.h and scan-code.h.

- Between Bison releases, manually append `+' to the previous Bison
- release number, and use that as a signal to automatically print the

- * ChangeLog: Add Id header.
- * configure.ac (AC_INIT): Append `+' to `2.3'.
- * src/.cvsignore: Add revision.c.
- * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
- (BUILT_SOURCES): Add revision.c.
- (revision.c): New target rule. This file defines a new global variable
- named revision. It initializes it with either the Id from ChangeLog
- or, if VERSION doesn't contain `+', with the empty string.
- * src/getargs.c (version): Print the value of revision.

-2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/glr.c (YYRECOVERING): Define to be a function-like macro
- with no arguments, not as an object-like macro. This is for
- compatibility with data/yacc.c. Problem reported by John P. Hartmann in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.
- * doc/bison.texinfo (Action Features, Error Recovery, Table of Symbols):

-
-2006-05-30 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * src/getargs.c (usage): Back out yesterday's modification of the

- releasing 2.3.
-
-2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
-
- * doc/bison.texinfo (Introduction): Don't say "GLR grammar".

-
-2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
- shell, not within 'make', so that 'make' by an ordinary builder
- (using GNU make) does not worry about configuring gzip. This also
- works around a bug reported independently by Keith Thompson and by
- Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
- stderr rather than stdout, messing up the build logs.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
- to make sure that YYID will never be unused. This fixes a 'make
- maintainer-check' failure caused by the recent changes to the 'Trivial
- grammars' test case, which caused g++ 4.1.0 to complain that YYID was
- not used.
- * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
-
-2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
- state before an empty RHS is always resolved here. Only the location
- of that state is guaranteed to be resolved, and that's enough. This
- fixes the remaining bug reported by Derek M. Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * tests/glr-regression.at (Uninitialized location when reporting
- ambiguity): Test the above case.
- Also, the embedded comments in this test case claim it checks the case
- of an empty RHS that has inherited the initial location. However, the
- corresponding LHS was already resolved, so yyresolveLocations didn't
- actually have reason to modify it. Fix this by forcing
- nondeterministic operation at the beginning of the parse.
-
-2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
-
- * data/c.m4 (b4_yy_symbol_print_generate):
- (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
- 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
- of the bugs reported today by Derek M Jones in
- <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
- * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
- defined to be a type name without parens or brackets.
- (Location Type): Similarly for YYLTYPE.
- * tests/regression.at (Trivial grammars): Put in a test for this
- bug that will be caught by 'make maintainer-check' (though not,
- alas, by 'make check' unless your compiler is picky).

-2006-03-08 Joel E. Denny <jdenny@ces.clemson.edu>
-
- * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web

- now unnecessary yystackp parameter.
- (yyresolveValue): Return yyreportAmbiguity's result. Now the necessary
- destructors can be called.

- * tests/glr-regression.at: Don't invoke bison with `-t' unnecessarily
- in existing testcases.
-
-2006-03-02 Joel E. Denny <jdenny@ces.clemson.edu>
-
- Don't leak semantic values for parent RHS when a user action cuts the
- parser, and clean up related code a bit.
- * tests/glr-regression.at (Leaked merged semantic value if user action
- cuts parse): Rename to...
- (Leaked semantic values if user action cuts parse): ... this. Add check
- for leaked parent RHS values.
- * data/glr.c (yydestroyGLRState): In debugging output, distinguish
- between an unresolved state (non-empty chain of semantic options) and
- an incomplete one (signaled by an empty chain).
- (yyresolveStates): Document the interface. Move all manipulation of a
- successfully or unsuccessfully resolved yyGLRState to...
- (yyresolveValue): ... here so that yyresolveValue always leaves a
- yyGLRState with consistent data and thus is easier to understand.
- Remove the yyvalp and yylocp parameters since they are always just
- taken from the yys parameter. When reporting a discarded merged value
- in debugging output, note that it is incompletely merged. Document the
- interface.
- (yyresolveAction): If resolving any of the RHS states fails, destroy
- them all rather than leaking them. Thus, as long as user actions are
- written to clean up the RHS correctly, yyresolveAction always cleans up
- the RHS of a semantic option. Document the interface.

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

-
- * examples/calc++/Makefile.am (check_PROGRAMS): Renamed from

- * data/lalr1.cc (yytranslate_): No longer inline, to work around a
- porting problem to g++ 3.4.3 on Darwin 7.9.0, where g++ complained
- "warning: sorry: semantics of inline function static data `const
- unsigned char translate_table[262]' are wrong (you'll wind up with
- multiple copies)".
-
- * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
- or, xor to not_, and_, or_, and xor_, respectively. This works
- around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
- random system header somewhere that includes the equivalent of

-2006-01-30 Joel E. Denny <jdenny@ces.clemson.edu>
-
- During deterministic GLR operation, user actions should be able to
- influence the parse by changing yychar. To make this easier to fix and
- to make glr.c easier to evolve in general, don't maintain yytoken in
- parallel with yychar; just compute yytoken when needed.
- * tests/glr-regression.at (Incorrect lookahead during deterministic
- GLR): Check that setting yychar in a user action has the intended
- effect.
- * data/glr.c (yyGLRStack): Remove yytokenp member.
- (yyclearin): Don't set *yytokenp.
- (yyprocessOneStack, yyreportSyntaxError, yyrecoverSyntaxError): Examine

- normal case.
-
- Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
- got from <http://bro-ids.org/download.html>. The bug is that
- when two actions appeared in succession, the second one was
- scanned before the first one was added to the grammar rule
- as a midrule action. Bison then output the incorrect warning
- "parse.y:905.17-906.36: warning: unused value: $3".
- * src/parse-gram.y (BRACED_CODE, action): These are no longer
- associated with a value.
- (rhs): Don't invoke grammar_current_rule_action_append.
- (action): Invoke it here instead.
- * src/reader.c (grammar_midrule_action): Now extern.

- (<INITIAL>"{"): Invoke grammar_midrule_action if the current
- rule already has an action.
- (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
- * tests/input.at (AT_CHECK_UNUSED_VALUES):
- Add some tests to check that the above changes fixed the bug.
-
-2006-01-27 Paul Eggert <eggert@cs.ucla.edu>

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

- * doc/bison.texinfo (Bison Parser): Document that users can't
- arbitrarily use malloc and free for other purposes. Document

- (yysyntax_error): New function.
- (yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
- multiple syntax errors are reported, and alloca is being used.
- Instead, reallocate buffers twice as big each time, so that

- All callers changed.
- * tests/glr-regression-at (make_value): Args are const pointers now,
- to avoid GCC warning.

- patch.
-
-2005-09-11 Paul Eggert <eggert@cs.ucla.edu>
-
- * Makefile.am (EXTRA_DIST): Do not distribute REFERENCES; it

- separate file anyway.
- * data/glr.c [defined YYSETJMP]: Don't include <setjmp.h>.
- (YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.

- All callers changed to avoid the newline.
- (yyprocessOneStack): Output two lines rather than one, to accommodate

- reported by Joel E. Denny in
- <http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00004.html>

-
- * NEWS: Version 2.0b.
-
- * Makefile.am (SUBDIRS): Put examples before tests, so that
- "make check" doesn't finish with "All 1 tests passed".
-
- * tests/regression.at (Token definitions): Don't rely on
- AT_PARSER_CHECK for data that contains backslashes. It currently
- uses 'echo', and 'echo' isn't portable if its argument contains
- backslashes. Problem found on OpenBSD 3.4. Also, do not assume
- that the byte '\0xff' is not printable in the C locale; it is,
- under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
- not printable, so use '\0x81' to test.
-
- * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
- version of GCC, since the macro is used with non-GCC compilers.
-
- Fix core dump reported by Pablo De Napoli in
- <http://lists.gnu.org/archive/html/bug-bison/2005-07/msg00053.html>.
- * tests/regression.at (Invalid inputs with {}): New test.
- * src/parse-gram.y (token_name): Translate type before using
- it as an index.
-
- * data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on

- ((__unused__)).
- (yyFail, yyMemoryExhausted, yyreportAmbiguity):
- Add __attribute__ ((__noreturn__)).
-
- * etc/clcommit: Remove. We weren't using it, and it failed
- "make maintainer-distcheck".
- * Makefile.maint: Merge from coreutils.
- (CVS_LIST, CVS_LIST_EXCEPT): New macros.
- (syntax-check-rules): Change list of rules as described below.

- Restore old updating code, even though we don't use it, so
- that we're the same as coreutils.
- (alpha, beta, major): Depend on news-date-check.
- Make the upload commands.

- * src/output.c: Include scan-skel.h.
- (scan_skel): Remove decl, since scan-skel.h does this.
- (output_skeleton):
- Indent calls to "error" to pacify "make maintainer-distcheck".
- * src/print_graph.c: Don't include <obstack.h>, as system.h does this.

-
-2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac: Update version number.
-
- * Makefile.am (SUBDIRS): Add examples; somehow this got removed
- accidentally.

- autogenerated by the maintainer.

-
- * po/POTFILES.in: Add lib/xalloc-die.c; remove lib/xmalloc.c.
-
- * src/relation.c (relation_transpose): Rewrite to avoid bogus complaint
- from maintainer-distcheck about casting the argument of 'free'.
-
- * NEWS: Mention recent yytname changes.
- * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
-
- * bootstrap: For translations that have not yet been upgraded to
- the new runtime-po domain, prime the pump by extracting the

-
- * src/scan-gram.l (<SC_PRE_CODE>.): Don't double-quote token names,

- (yyerrlab): Use it to decode most string literals.
- * doc/bison.texinfo (Decl Summary, Calling Convention):

- Undo most 2005-04-17 change here, too.
-
-2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix more problems reported by twlevo@xs4all.nl.
- * tests/cxx-type.at: Don't pipe output of ./types through sed to
- remove trailing spaces. This loses the exit status of ./types,
- and isn't needed since ./types shouldn't be emitting trailing
- spaces.
- * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
- as the stack isn't valid in that case.
-
- * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
- (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):

-
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Work even with
- overly-picky compilers that reject 'char *foo = "bar";'.
-
- * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
- to FILE * parameter, not to stderr. This fixes a typo introduced
- in the 2005-07-12 change.
-
- * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
- warnings from GCC 4.
-
- * data/glr.c (yyexpandGLRStack, yyaddDeferredAction, yyexpandGLRStack):

-
- Destructor cleanups and regularization among the three skeletons.
- * NEWS: Document the behavior changes.
- * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
- stack before failing, as the cleanup code will do it for us now.
- * data/lalr1.cc (yyerrlab): Likewise.
- * data/glr.c (yyparse): Pop everything off the stack before
- freeing it, so that destructors get called properly.
- * data/lalr1.cc (yyreturn): Likewise.
- * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
- This is more consistent.
- * doc/bison.texinfo (Destructor Decl): Mention more reasons
- why destructors might be called. 1.875 -> 2.1.
- (Destructor Decl, Decl Summary, Table of Symbols):
- Some English-language cleanups for %destructor.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Add output line for destructor of start symbol.
- * tests/calc.at (AT_CHECK_CALC): Add one to line counts,
- because of that same extra output line.
-
- * NEWS: Document minor wording changes in diagnostics of
- Bison-generated parsers.
- * data/glr.c (yyMemoryExhausted): Renamed from yyStackOverflow.
- Remove unused formals. All uses changed.
- (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
- (yyparse): Rename yyoverflowlab to yyexhaustedlab.
- * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
- Rename yyoverflowab to yyexhaustedlab.
- When memory exhaustion occurs during syntax-error reporting,
- report it separately rather than in a single diagnostic; this
- eases translation.
- * doc/bison.texinfo (Memory Management): Renamed from Stack Overflow.
- (Memory Exhausted): Renamed from Parser Stack Overflow.
- Revamp wording slightly to prefer "memory exhaustion".
- * tests/actions.at: "parser stack overflow" -> "memory exhausted".
-
- * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
-
- Add i18n support to the GLR skeleton. Partially fix the C++
- skeleton; a C++ expert needs to finish this. Remove debugging
- msgids; there's little point to having them translated, since they
- can be understood only by someone who can read the
- (English-language) source code.
-
- Generate runtime-po/bison-runtime.pot automatically, so that we
- don't have to worry about garbage getting in that file. We'll
- make sure after the next official release that old msgids don't
- get lost. See
- <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
-
- * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
- Now auto-generated.
- * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
- Fix typos in explanations of the runtime file.
- * bootstrap: Change gettext keyword from YYI18N to YY_.
- Use standard Makefile.in.in in runtime-po, since we'll arrange
- for backward-compatible bison-runtime.po files in a different way.
- * data/glr.c (YY_): New macro, from yacc.c.
- (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
- Translate messages intended for users.
- (yyreportSyntaxError): Change "virtual memory" to "memory" to match
- the wording in the other skeletons. We don't know that the memory
- is virtual.

- Use same method that yacc.c uses.
- Don't translate debugging messages.
- (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
- it doesn't work (yet), and requires C++ expertise to fix.
- * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
- Move defn to a more logical place, to be consistent with other
- skeletons.
- Don't translate debugging messages.
- Don't assume line numbers fit in unsigned int; use unsigned long fmts.
- * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
- to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
- * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
-
- Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
- void, not int.
- * tests/glr-regression.at (Badly Collapsed GLR States):
- Likewise.
- (Improper handling of embedded actions and dollar(-N) in GLR parsers):
- yylex should return 0 at EOF rather than aborting.
-
- Improve tests for stack overflow in GLR parser.
- Problem reported by twlevo@xs4all.nl.
- * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
- All uses removed.
- (yyStackOverflow): Just longjmp, but with value 2 so that caller
- can handle the problem.
- (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
- (yyparse): New local variable yyresult to record the result.
- Use result of setjmp to set it, rather than storing itinto
- struct.
- (yyDone): Remove label.
- (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
- to mimic yacc.c. Do not discard lookahead if it's EOF (possible
- if YYABORT is used).
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
- yyparse status; put status > 1 into diagnostic.
- Check that status==2 works.
- * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
- Use exit status 3 for failure to open (which shouldn't happen).
-
-2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
-
- * tests/conflicts.at (%nonassoc and eof): Don't exit with status
- 1 on syntax error; just let yyparse do its thing.
- * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
- * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
- (Exploding the Stack Size with Alloca):
- (Exploding the Stack Size with Malloc):
- Expect exit status 2, not 1, since the parser is supposed to blow
- its stack. Problem reported by twlevo@xs4all.nl.
-
- * data/glr.c (yyparse): Don't assume that the initial calls
- to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
- Print a stack-overflow message and fail instead.
- Initialize the line-number information before creating the stack,
- so that the stack-overflow message can report line zero safely.
-
-2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
-
- Fix problems reported by twlevo@xs4all.nl.
- * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.

- sets): Declare yylex before using it.
- * tests/Makefile.am (maintainer-check-g++): Fix a stray
- $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
- test for valgrind; valgrind is independent of g++.
- (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
- for compatibility with POSIX 1003.1-2001 (if running coreutils).
- * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
- Use a destructor, so that we can expand the stack. Change
- YYSTYPE to char * so that we can free it. Cast result of malloc.

- Put comment before action, since older 'make' can't handle comment
- in action.
- $(BUILT_SOURCES): List all built sources, not just some of them.
- $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
- $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.

-2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
-

- never had any % directives, we can simply pass it to yyerror.
- (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
- be modified later, as that is the usual style in glr.c.
- Problems reported by Paul Hilfinger.
-
- Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
- and size overflow errors.
- * data/glr.c: Include <stdio.h> etc. after user prolog, not before,

- than vsprintf. Allocate a bigger buffer if possible.
- Report an error if buffer allocation fails.
- (yyStackOverflow): New function.

- the initialization was successful. It might fail if storage was
- exhausted.

- Don't assume stack number fits in int.
- (yysplitStack): Check for storage allocation failure.

-
- * NEWS: Bison-generated parsers no longer default to using the

- to widespread problems in unchecked stack-overflow detection.
- * data/glr.c (YYMAXDEPTH): Remove undef when zero. It's the user's

- specify a value that is not a preprocessor constant.

- Returning a bool introduces a problem: 0 corresponds to false, and

-
- Remove uses of 'short int' and 'unsigned short int'. This raises
- some arbitrary limits. It uses more memory but nowadays that's
- not much of an issue.
-
- This change does not affect the generated parsers; that's a different
- task, as some users will want to conserve memory there.
-
- Ideally we should use size_t to represent all object counts, and
- something like ptrdiff_t to represent signed differences of object
- counts; but that will require more code-cleanup than I have the
- time to do right now.

-
-2004-10-05 Akim Demaille <akim@epita.fr>
-
- In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
- whether the reducion was empty or not. This leaves room to
- improve the use of YYLLOC_DEFAULT in such a case.
- lalr1.cc is still experimental, so changing this is acceptable.
- And finally, there are probably not many users who changed the
- handling of locations in GLR, so changing is admissible too.
-
- * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
- empty reduction, set @$ to an empty location ending the previously
- stacked symbol.
- Adjust uses to make sure the code is triggered on empty
- reductions.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
- expected output: empty reductions have empty locations.
-

-
- * data/lalr1.cc: Reinstall the former ctor, for sake of

- type* var).
-
-2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
-
- * src/parse-gram.y (add_param): Rewrite to avoid strchr,

-2004-09-20 Akim Demaille <akim@epita.fr>
-
- Let the initial-action act on the look-ahead, and use it for the
- "initial push" (corresponding to an hypothetical beginning-of-file).
- And let lalr1.cc honor %initial-action.
-
- * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
- example.
- * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.

- Also, honor initial-actions.
-
-2004-09-20 Akim Demaille <akim@epita.fr>
-

- Define when we know YYLTYPE's structure, i.e., when the default
- YYLLOC_DEFAULT is used.
- * data/c.m4 (b4_yysymprint_generate): Use it.
- * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
- value of the result.
- (error_start_): Replace with...
- (error_range_): this location array.
- This allows to replace code relying on the implementation of
- locations by portable code.
- * data/yacc.c (yylerrsp): Replace with...
- (yyerror_range): this.
- Every time a token is popped, update yyerror_range[0], to have an
- accurate location for the error token.
- * data/glr.c (YY_LOCATION_PRINT): New.
- (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:

-
- * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
- (iterator, const_iterator): these, to be more in the C++ spirit.
- Also, return reverse iterators so that when displaying the stack
- we display its bottom first.
- (Parser::stack_print_, Parser::reduce_print_): Match the messages
- from yacc.c.
- We should probably use vector here though.
-
-2004-09-16 Akim Demaille <akim@epita.fr>
-
- Have more complete shift traces.
-
- * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT

- * data/lalr1.cc (symprint_): Output the location.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
- output the location within the %printer.
- Activate GLR tests, at least to make sure they compile properly.
- They still don't pass though.
- * tests/calc.at: Adjust expect verbose output, since now "Entering
- state..." is on a different line than the "Shifting" message.
-
-2004-09-08 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
- Bison directive from the Bison file to the invocation of this
- macro, so that these directives are passed to
- AT_BISON_OPTION_PUSHDEFS to get correct help macros.
- Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
- Move the AT_SETUP/AT_CLEANUP outside, to report as test title
- the extra Bison directives instead of the whole series.
- Change the grammar so that there are recoverable errors, and
- unrecoverable errors. Now we can have the parser give up before
- consuming the whole input. As a result we now can observe that
- the lookahead is freed when needed.
- Change the parser source to parse argv[1] instead of a hard coded
- string.
- Simplify yylex, and give a value and location to EOF.
- Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
- passed directives already coded in the file.
- Add some tests to check the location of "error".
- For some tests, the C++ parser is correct, and not yacc.c.
- For other tests, they provide different, but unsatisfying, values,
- so keep the C++ value so that at least one parser is "correct"
- according to the test suite.
- (Actions after errors): Remove, this is subsumed by the
- AT_CHECK_PRINTER_AND_DESTRUCTOR series.
-
-2004-09-06 Akim Demaille <akim@epita.fr>

- argument, an informative message.
- Call YY_SYMBOL_PRINT.
- Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
- * data/lalr1.cc (destruct_): Likewise.
- In addition, no longer depend on b4_yysymprint_generate and
- b4_yydestruct_generate to generate these functions, do it "by

- Use it consistently instead of token/nterm debugging output by

- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
- %printer calls to use cdebug_ when using lalr1.cc.
-

- Spent a few hours checking out which prerequisite versions the
- current sources actually require. I went all the way back to
- Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
- a seemingly endless set of combinations of versions more recent
- than that. The bottom line is that the current sources require
- fairly recent versions of the build tools, and it'll be some work
- to change this.
- * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
- (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
- (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
- Add comments explaining why those particular versions are
- currently needed.
-
- * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
- in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
- <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
-
- * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
- (it fails with a Autoconf-without-aclocal-m4 diagnostic).
-
-2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
-
- * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
- 0.11.5. Suggested by Bruno Haible.

- gettext better.
-
- * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
- put into the -d output file, and mention what to do if YYSTYPE is
- defined as a macro.
-
-2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
-
- Undo change made earlier today: it caused autopoint to not bring
- in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
- autopoint's.
-
- * bootstrap: Check that gettext version matches what's in
- configure.ac. Warn users to ignore robots.txt ERROR 404.
- * bootstrap: Undo today's earlier change (logged below).
- * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
-
- The gettext version checking is causing more trouble than it's
- curing; remove it. Problem reported by Paul Hilfinger.

- * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
-

- * bootstrap: Bootstrap from gnulib and po repositories.
- Much of this code was stolen from GNU diff and GNU tar's bootstrap.
- * README-cvs: Document these changes. Remove version numbers from

-
- * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
- (gl_USE_SYSTEM_EXTENSIONS): Add.

- for us.
-
- * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".

-
- * lib/subpipe.h [HAVE_SYS_TYPES_H]: Include <sys/types.h>,
- so that this include file can stand alone.

-2004-02-02 Paul Eggert <eggert@twinsun.com>
-

-
- * tests/local.at: Require Autoconf 2.59's Autotest.
- * tests/testsuite.at: Don't include local.at, since we now assume

- non-modifiable lvalue, instead of a modifiable one.
- * doc/bison.texinfo (Actions): Document that $$ can

- When reducing initial empty rules, Bison parser read an initial
- location that is not defined. This results in garbage, and that
- affects Bison's own parser. Therefore we need (i) to extend Bison
- to support a means to initialize this location, and (ii) to use
- this CVS Bison to fix CVS Bison's parser.

- (YYERROR): Goto to yyerrorlab, not yyerrlab1.

- yyerrlab), when hitting EOF, pop the whole stack here instead of
- merely falling thru the default error handling mechanism.
- (yyerrorlab): New label, with the old contents of YYERROR,

-
-2003-06-02 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Position::lines, yy::Position::columns,

-
-2003-06-01 Paul Eggert <eggert@twinsun.com>

-
- Fix a GLR parser bug I reported in February; see
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
- The problem was that GLR parsers did not conform to the C standard,
- because actions like { $1 = $2 + $3; } expanded to expressions
- that invoked YYFILL in separate subexpressions, and YYFILL assigned
- to a local variable. The C standard says that expressions
- like (var = f ()) + (var = f ()) have undefined behavior.
- Another problem was that GCC sometimes issues warnings that
- yyfill and its parameters are unused.
-
- * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
- as possibly unused.
- (yyfill): New function.
- (YYFILL): Use it.
- (yyuserAction): Change type of yynormal to bool, so that it matches
- the new yyfill signature. Mark it as possibly unused.
-
-
- Follow up on a bug I reported in February, where a Bison-generated
- parser can loop. Provide a test case and a fix for yacc.c. I
- don't have a fix for lalr1.cc or for glr.c, unfortunately.
- The original bug report is in:
- <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
-
- * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
- macro's size was becoming unwieldy.
- (yyerrlab): Do not discard an empty lookahead symbol, as this
- might destroy garbage.
- (yyerrorlab): New label, with the old contents of YYERROR,
- plus the following change: pop the stack of rhs corresponding
- to the production that invoked YYERROR. That is how Yacc
- behaves, and POSIX requires this behavior.
- (yyerrlab1): Use YYPOPSTACK instead of its definiens.
- * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
- Define 'alarm' to do nothing if unistd.h is not available.
- Add a new rule "exp: '-' error;" to test the above change to
- data/yacc.c. Use 'alarm' to abort any test taking longer than
- 10 seconds, as it's probably looping.
- (AT_CHECK_CALC): Test recovery from error in new grammar rule.
- Also, the new yacc.c generates two fewer diagnostics for an
- existing test.

- -ansi -Wall -gall).

- * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
- * src/getargs.c, src/getargs.h: here, as bool, not int.
- (nondeterministic_parser): New.
- * src/parse-gram.y, src/scan-gram.l: Support
- %nondeterministic-parser.
- * src/output.c (prepare): Use nondeterministic_parser instead
- of glr_parser where appropriate.
- * src/tables.c (conflict_row, action_row, save_row)
- (token_actions, token_actions, pack_vector): Ditto.
-
-2003-04-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
-
-2003-04-29 Akim Demaille <akim@epita.fr>
-
- * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
- with %pure-parser and %locations to exercise the patch from Yakov
- Markovitch below.
-
-2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
-
- * data/yacc.c: (b4_lex_param): Corrected for the case where
- %lex-param is provided and %pure-parser isn't.
-
-2003-04-27 Paul Eggert <eggert@twinsun.com>
-
- Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
- * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
- if it is not defined.
- (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
-
-2003-04-26 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
- Declare to be of type suitable for the ninf value itself, not of
- type suitable for the corresponding table, since the latter might
- be unsigned but the ninf value might be negative. This fixes a
- bug reported by Alexandre Duret-Lutz in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
-
- * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
- invokes it. We shouldn't invoke it twice because it will attempt
- to put error.o in the archive twice. This fixes a glitch reported
- by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
-
-2003-04-21 Paul Eggert <eggert@twinsun.com>
-
- * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch

-
- * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
- Fix obvious typo that results in uncompilable GLR parsers
- when both %pure-parser and %locations are used. (trivial change)
-
-2003-04-17 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l: Add %option nounput, since we no longer use unput.
- (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
- Do not insert the expected token via unput, as this runs afoul
- of a POSIX-compatibility bug in flex 2.5.31.
- All uses changed to BEGIN the parent state,
- since we no longer insert the expected token via unput.
- * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
- that is no longer emitted after the above change.
-
- * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
- the first one. This change is from Paul Hilfinger, and it fixes
- regression reported by Werner Lemberg in
- <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
-
- (resolve_sr_conflict): Don't invoke state_errs_set
- unless one or more tokens have been explicitly made errors.
- Otherwise, the above change causes Bison to abort.
-
- * tests/existing.at (GNU pic Grammar): New test case, taken from
- Lemberg's email.
-
-2003-03-31 Akim Demaille <akim@epita.fr>

-
- * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
- From Paul Hilfinger.
-
-2003-03-29 Akim Demaille <akim@epita.fr>
-
- * m4/error.m4: Do not put under dynamic conditions some code which
- expansion is under static control.
-
-2003-03-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
-
-2003-03-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo (Strings are Destroyed): New.
-
-2003-03-13 Paul Eggert <eggert@twinsun.com>
-

- * tests/.cvsignore: Add testsuite.log.
- * doc/fdl.texi: Sync with latest FSF version.

-2003-03-12 Paul Eggert <eggert@twinsun.com>
-
- * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
- (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
- cursor, instead of leaving it undefined. This fixes a bug
- reported by Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
- * tests/input.at (Torturing the Scanner): Test the scanner on
- an empty input file, which was Tim Van Holder's test case.
-
- * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
- <sys/resource.h> can be included, include sys/time.h and
- sys/times.h first, if available. This works around the SunOS
- 4.1.4 porting bug reported by Bruce Becker in
- <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
-
- * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
- AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
- AC_HEADER_SYS_WAIT.
-
- Merge changes from gnulib. This was prompted because the CVS
- snapshot didn't build on Solaris 7 due to strnlen problems.
-
- These changes need to be merged back into gnulib:
- * lib/hash.c: Include <stdbool.h> unconditionally.
- * m4/onceonly.m4 (m4_quote): New macro.
- (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

-
-2003-03-02 Akim Demaille <akim@epita.fr>
-
- * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
- generate verbose error messages.

- cannot be a non terminal.
-
-2003-03-02 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
- message.
-
-2003-03-02 Akim Demaille <akim@epita.fr>

-
-2003-03-01 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
- not loc->end, since loc->end might contain garbage and this leads
- to undefined behavior on some platforms.
- (id_loc, token_start): Use (IF_LINTed) initial values that do not
- depend on *loc, so that the reader doesn't give the the false
- impression that *loc is initialized.
- (<INITIAL>"%%"): Do not bother setting code_start, since its value
- does not survive the return.
-
-2003-03-01 Akim Demaille <akim@epita.fr>
-
- * src/scan-gram.l (code_start): Always initialize it when entering
- into yylex, as SC_EPILOGUE is activated *before* the corresponding
- yylex invocation. An alternative would be making it static, but
- then it starts with the second %%'s beginning, instead of its end.
-
-2003-02-28 Paul Eggert <eggert@twinsun.com>
-
- * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
- around a UnixWare 7.1.1 porting bug reported by John Hughes in
- <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.

- Suggested by Paul Eggert.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): Make sure "columns" never pushes
- before initial_columns.
- (location.hh): Use consistent variable names when defining the
- operator<<.
- Use "last" so that we subtract from Positions, not from unsigned.
-
-2003-02-20 Akim Demaille <akim@epita.fr>
-
- * data/lalr1.cc (position.hh): New subfile, including the extended
- and Doxygen'ed documentation of class Position.

- AT_YACC_IF.
- Redefine AT_YYERROR_SEES_LOC_IF using it.
- (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
- not defined.
- Don't use the location in yy::Parser::error_ and
- yy::Parser::print_ when not %locations.
- Activate more lalr1.cc tests.
-
-2003-02-19 Akim Demaille <akim@epita.fr>

- error recovery, mixing with/without pops and discarding of the
- lookahead.
- Exercise YYERROR.
- Disable the lalr1.cc tests as currently it doesn't support YYERROR.
-
-2003-02-17 Paul Eggert <eggert@twinsun.com>
-
- * tests/atlocal.in (LDFLAGS, LIBS): New vars.
- * tests/testsuite.at (AT_COMPILE): Use them.
- This fixes the testsuite problem reported by Robert Lentz in
- <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
-
-2003-02-12 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:

- * tests/testsuite.at (AT_COMPILE_CXX): New.
- * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
- locations in a more synthetic way.
- (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if

-
-2003-02-02 Akim Demaille <akim@epita.fr>
-

-
- * po/LINGUAS: Add ms.
-
-2003-01-30 Akim Demaille <akim@epita.fr>
-
- * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
-
-2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
-
- * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
- of $1.
-
- Changes in response to error report by S. Eken: GLR mode does not
- handle negative $ indices or $ indices in embedded rules correctly.
- See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
-
- * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
- (b4_rhs_location): Ditto.
- (yyfill): New function to copy from stack tree into array
- incrementally.
- (yyuserAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- Define YYFILL to use in user-defined actions to fill semantic array
- as needed.
- Remove dummy use of yystack, as there is now a guaranteed use.
- (yydoAction): Modify to allow incremental move of semantic values
- to rhs array when in GLR mode.
- (yyresolveAction): Ditto.
- (yyglrShiftDefer): Update comment.
- (yyresolveStates): Use X == NULL for pointers, not !X.
- (yyglrReduce): Ditto.

-2003-01-28 Paul Eggert <eggert@twinsun.com>
-
- * data/lalr1.cc: Do not use @output_header_name@ unless
- b4_defines_flag is set. This fixes two bugs reported by
- Tim Van Holder in
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
- and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
-
-2003-01-21 Paul Eggert <eggert@twinsun.com>
-
- * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
- we don't need to worry about yyerrlab1 being reported as an
- "unused label" by non-GCC C compilers. The downside is that if
- locations are used then a couple of statements are duplicated each
- time YYERROR is invoked, but the upside is that the warnings
- should vanish.
- (yyerrlab1): Move code to YERROR.
- (yyerrlab2): Remove. Change uses back to yyerrlab1.
- This reverts some of the 2002-12-27 change.
-
-2003-01-17 Paul Eggert <eggert@twinsun.com>
-
- * src/output.c (symbol_printers_output): Fix typo that led
- to core dump. Problem reported by Antonio Rus in
- <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
-
-2003-01-13 Akim Demaille <akim@epita.fr>,
- Quoc Peyrot <chojin@lrde.epita.fr>,
- Robert Anisko <anisko_r@lrde.epita.fr>
-
- * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
- when the stacks contain one element, as the loop would otherwise
- free the last state, and then use the top state (the one we just
- popped). This means that the initial elements will not be freed
- explicitly, as is the case in yacc.c; it is not a problem, as

-
-2003-01-03 Paul Eggert <eggert@twinsun.com>
-
- * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
- (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5

- (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
-

-
-2002-12-30 Paul Eggert <eggert@twinsun.com>
-
- * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
- Moved here from...
- (<INITIAL>","): Here. This causes stray "," to be treated
- more uniformly.
-
- * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
- last brace in braced code when not in Yacc mode, for compatibility
- with Bison 1.35. This resurrects the 2001-12-15 patch to
- src/reader.c.
-
- * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
- yystype. This follows up the 2002-12-24 YYSTYPE bug fix.

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

-2002-12-27 Paul Eggert <eggert@twinsun.com>
-
- Fix a bug where error locations were not being recorded correctly.
- This problem was originally reported by Paul Hilfinger in
- <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
-
- * data/yacc.c (yyparse): New local var yylerrsp, to record the
- top of the location stack's error locations.
- (yyerrlab): Set it. When discarding a token, push its location
- onto yylerrsp so that we don't lose track of the error's end.
- (yyerrlab1): Now is only the target of YYERROR, so that we can
- properly record the location of the action that failed. For GCC
- 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
- GCC warning about yyerrlab1 being unused if YYERROR is unused.
- (yyerrlab2): New label, which yyerrlab now falls through to.
- Compute the error's location by applying YYLLOC_DEFAULT to
- the locations of all the symbols that went into the error.
- * doc/bison.texinfo (Location Default Action): Mention that
- YYLLOC_DEFAULT is also invoked for syntax errors.
- * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
- Error locations include the locations of all the tokens that were
- discarded, not just the last token.
-
-2002-12-26 Paul Eggert <eggert@twinsun.com>
-
- * src/files.c: Include quote.h.
- (compute_output_file_names): Warn if we detect conflicting
- outputs to the same file. This should catch the misunderstanding
- exemplified by Debian Bug 165349, reported by Bruce Stephens..
-
- * src/conflicts.c (conflicts_print): If the user specifies
- "%expect N", report an error if there are any reduce/reduce
- conflicts. This is what the manual says should happen.
- This fixes Debian bug 130890, reported by Anthony DeRobertis.
- * tests/conflicts.at (%expect with reduce conflicts): New test.
-
- Don't use m4_include on relative file names, as it doesn't work as
- desired if there happens to be a file with that name under ".".
-
- * m4sugar/version.m4: Remove; it was included but it wasn't used.
- * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
- * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
- * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
- * src/output.c (output_skeleton): Use full path names when
- specifying a file to include; don't rely on include path, as
- it's unreliable when the working file contains a file with
- that name.
-
-2002-12-25 Paul Eggert <eggert@twinsun.com>
-
- Remove obsolete references to bison.simple and bison.hairy.
- Problem mentioned by Aubin Mahe in
- <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
- * data/glr.c: Comment fix.
- * doc/bison.1: Remove references. Also, mention "yacc".
-
- * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
- with -g option.
-
- * src/parse-gram.y (declaration): Use enum "report_states" rather
- than its numeric value 1.
-
- * src/scan-skel.l ("@output ".*\n): Close any old yyout before
- opening a new one. This fixes Debian bug 165349, reported by
- Bruce Stephens.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- Version 1.75e.
-
- * Makefile.maint (cvs-update): Don't assume that the shell
- supports $(...), as Solaris sh doesn't.
-
- * src/parse-gram.y (lloc_default): Remove test for empty
- nonterminals at the end, since it didn't change the result.
-
-2002-12-24 Paul Eggert <eggert@twinsun.com>
-
- If the user does not define YYSTYPE as a macro, Bison now declares it
- using typedef instead of defining it as a macro. POSIX requires this.
- For consistency, YYLTYPE is also declared instead of defined.
-
- %union directives can now have a tag before the `{', e.g., the
- directive `%union foo {...}' now generates the C code
- `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
- The default union tag is `YYSTYPE', for compatibility with Solaris 9
- Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
- instead of `yyltype'.
-
- `yystype' and `yyltype' are now obsolescent macros instead of being
- typedefs or tags; they are no longer documented and will be
- withdrawn in a future release.
-
- * data/glr.c (b4_location_type): Remove.
- (YYSTYPE): Renamed from yystype.
- (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
- (struct YYLTYPE): Renamed from struct yyltype.
- (YYLTYPE): Renamed from yyltype.
- (yyltype, yystype): New (and obsolescent) macros,
- for backward compatibility.
- * data/yacc.c: Likewise.
-
- * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
- does not specify a union tag. This is for compatibility with
- Solaris 9 yacc.
-
- * src/parse-gram.y (add_param): 2nd arg is now char * not char
- const *, since it is now modified by stripping surrounding { }.
- (current_braced_code): Remove.
- (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
- PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
- trailing " {...}". Now of type <chars>.
- (grammar_declaration): Adjust to bundled tokens.
- (code_content): Remove; stripping is now done by add_param.
- (print_token_value): Print contents of bundled tokens.
- (token_name): New function.
-
- * src/reader.h (braced_code, current_braced_code): Remove.
- (token_name): New decl.
-
- * src/scan-gram.l (handle_dollar, handle_at): Now takes int
- token_type, not braced_code code_kind. All uses changed.
- (SC_PRE_CODE): New state, for scanning after a keyword that
- has (or usually has) an immediately-following braced code.
- (token_type): New local var, to keep track of which token type
- to return when scanning braced code.
- (<INITIAL>"%destructor", <INITIAL>"%lex-param",
- <INITIAL>"%parse-param", <INITIAL>"%printer",
- <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
- instead of returning a token type immediately.
- (<INITIAL>"{"): Set token type.
- (<SC_BRACED_CODE>"}"): Use it.
- (handle_action_dollar, handle_action_at): Now returns bool
- indicating success. Fail if ! current_rule; this prevents a core dump.
- (handle_symbol_code_dollar, handle_symbol_code_at):
- Remove; merge body into caller.
- (handle_dollar, handle_at): Complain in invalid contexts.
-
- * NEWS, doc/bison.texinfo: Document the above.
- * NEWS: Fix years and program names in copyright notice.
-
-2002-12-17 Paul Eggert <eggert@twinsun.com>
-
- * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
- Reporting, Table of Symbols): Omit mentions of %lex-param and
- %parse-param from the documentation for now.
-
-2002-12-15 Paul Eggert <eggert@twinsun.com>
-
- Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
- GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
- lookahead symbol, and which sets yychar in parser actions) and it
- disagreed with the Bison documentation. Bug
- reported by Andrew Walrond.
-
- * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
- as the caller now does that.
- (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
- (YYEMPTY): Parenthesize right hand side, since others use it.
- (yyparse): Don't assume that our generated code is the only code
- that sets yychar.

-2002-12-08 Paul Eggert <eggert@twinsun.com>
-
- * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
- since this causes problems when __file__ contains character
- sequences like "@" that are treated specially by src/scan-skel.l.

- reported by Martin Mokrejs in
- <http://lists.gnu.org/archive/html/bug-bison/2002-12/msg00007.html>.

- be declared before being used. E.g., one should typically
- declare them in the prologue. Use GNU coding style in examples.
- Put "const" consistently after the type it modifies. Mention
- that C99 supports "inline". Mention that yyerror traditionally
- returns "int".

- unnecessarily alarming people when the test fails.
-
- * data/yacc.c (yyerrlab1): Move this label down, so that the
- parser does not discard the lookahead token if the user code
- invokes YYERROR. This change is required for POSIX conformance.

-
- * tests/input.at (Torturing the Scanner): Surround the
- backslash-newline tests with "#if 0", to make it less likely that

- problems. Among other things, this fixes the Bison bug reported
- by Jan Hubicka when processing the Bash grammar; see:
- <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
-
- Use new @ escapes consistently. Represent brackets with @{ and @}
- rather than @<:@ and @:>@, since this works a bit better with dumb
- editors like vi. Represent @ with @@, since @ is now consistently
- an escape. Use @oline@ and @ofile@ rather than __oline__ and
- __ofile__, to avoid unexpected expansions. Similarly, use @output
- rather than #output.
-
- * data/c.m4 (b4_copyright): Omit file name from comment, since
- the file name could contain "*/".

-
- * src/files.c (output_infix): Remove; all uses removed.

- * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
-
- * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.

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

-
- * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
- them with auto vars.

- Abort if a stray escape character is found. Avoid unbounded input
- buffer when parsing non-escaped text.
-
- * tests/input.at (Torturing the Scanner): Add tests that @oline@,
- __oline__, #output, $@, and @{ do not have unintended meanings.
-
-2002-11-09 Paul Eggert <eggert@twinsun.com>
-
- Fix the test failure due to GCC warnings described in

- table.
- (yygetLRActions, yyrecoverParseError): Use them.
-
- * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
- counted in the token inserted at end of file. Now takes

- AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
- AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
- abort ();'. This reduces the runtime of the "Many lookaheads"
- test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
- GCC 3.2.
-
-2002-11-07 Paul Eggert <eggert@twinsun.com>
-
- * src/parse-gram.y (CHARACTER): Remove unused token.
- All uses removed.
-
- * src/scan-gram.l: Remove stack option. We no longer use the
- stack, since the stack was never deeper than 1; instead, use the
- new auto var c_context to record the stacked value.
-
- Remove nounput option. At an unexpected end of file, we now unput
- the minimal input necessary to end cleanly; this simplifies the
- code.
-
- Avoid unbounded token sizes where this is easy.
-
- (unexpected_end_of_file): New function.
- Use it to systematize the error message on unexpected EOF.
- (last-string): Now auto, not static.
- (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.

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

- * lib/lbitset.c: Likewise.
-
- * lib/abitset.c (abitset_bytes): Return a size that is aligned

- * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
-

-
- Fix `%nonassoc and eof'.
-
- * src/state.c (errs_dup): Aaaah! The failure was due to bytes

-2002-01-25 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (%nonassoc and eof): New.
- Suggested by Robert Anisko.

-
- * lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
- canonical definition.

-
-2002-01-06 Akim Demaille <akim@epita.fr>
-

-
-2002-01-03 Akim Demaille <akim@epita.fr>

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

-2002-01-02 Akim Demaille <akim@epita.fr>
-
- Equip the skeleton chain with location tracking, runtime trace,
- pure parser and scanner.
-
- * src/parse-skel.y: Request a pure parser, locations, and prefix
- renaming.
- (%union): Having several members with the same type does not help
- type mismatches, simplify.
- (YYPRINT, yyprint): New.
- (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
- (skel_error): this.
- Handle locations.
- * src/scan-skel.l: Adjust to these changes.
- * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
- (LOCATION_PRINT, skel_control_t): New.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/parse-skel.y: Get rid of the shift/reduce conflict:
- replace `gb' with BLANKS.
- * src/scan-skel.l: Adjust.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/system.h: We don't need nor want bcopy.
- Throw away MS-DOS crap: we don't need getpid.
- * configure.in: We don't need strndup. It was even causing
- problems: because Flex includes the headers *before* us,
- _GNU_SOURCE is not defined by config.h, and therefore strndup was
- not visible.
- * lib/xstrndup.c: New.
- * src/scan-skel.l: Use it.
- Be sure to initialize yylval.muscle member when scanning a MUSCLE.
- * src/parse-skel.y: Use %directives instead of #defines.
-
-2001-12-30 Akim Demaille <akim@epita.fr>
-
- * src/skeleton.h: New.
- * src/output.c (output_parser, output_master_parser): Remove, dead
- code.
- * src/output.h (get_lines_number, actions_output, guards_output)
- (token_definitions_output): Prototype them.
- * src/parse-skel.y: Add the license notice.
- Include output.h and skeleton.h.
- (process_skeleton): Returns void, and takes a single parameter.
- * src/scan-skel.l: Add the license notice.
- Include skeleton.h.
- Don't use %option yylineno: it seems that then Flex imagines
- REJECT has been used, and therefore it won't reallocate its
- buffers (which makes no other sense to me than a bug). It results
- in warnings for `unused: yy_flex_realloc'.
-
-2001-12-30 Robert Anisko <robert.anisko@epita.fr>
-
- * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): ...to there.
- * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
- (MUSCLE_INSERT_PREFIX): Move from here...
-
- * src/bison.hairy: Add a section directive. Put braces around muscle
- names. This parser skeleton is still broken, but Bison should not
- choke on a bad muscle 'syntax'.
- * src/bison.simple: Add a section directive. Put braces around muscle
- names.
-
- * src/files.h (strsuffix, stringappend): Add declarations.
- (tab_extension): Add declaration.
- (short_base_name): Add declaration.
-
- * src/files.c (strsuffix, stringappend): No longer static. These
- functions are used in the skeleton parser.
- (tab_extension): New.
- (compute_base_names): Use the computations done in this function
- to guess if the generated parsers should have '.tab' in their
- names.
- (short_base_name): No longer static.
-
- * src/output.c (output_skeleton): New.
- (output): Disable call to output_master_parser, and give a try to
- a new skeleton handling system.
- (guards_output, actions_output): No longer static.
- (token_definitions_output, get_lines_number): No longer static.
-
- * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
-
- * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
- parse-skel.y.
-
- * src/parse-skel.y: New file.
- * src/scan-skel.l: New file.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- %name-prefix is broken.
-
- * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
- Adjust all dependencies.
- * tests/headers.at (export YYLTYPE): Strengthen this test: use
- %name-prefix.
-
- Renaming yylval but not yylloc is not consistent. Now we do.
-
- * src/bison.simple: Prefix yylloc if used.
- * doc/bison.texinfo (Decl Summary): Document that.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Promote `%long-directive' over
- `%long_directive'.
- Remove all references to fixed-output-files, yacc is enough.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
- user prologue. These are defaults.
- * tests/actions.at (Mid-rule actions): Make sure the user can
- define YYDEBUG and YYERROR_VERBOSE.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/output.c (header_output): Don't forget to export YYLTYPE and
- yylloc.
- * tests/headers.at (export YYLTYPE): New, make sure it does.
- * tests/regression.at (%union and --defines, Invalid CPP headers):
- Move to...
- * tests/headers.at: here.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/actions.at (Mid-rule actions): Output on a single line
- instead of several.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * doc/bison.texinfo: Formatting changes.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Don't store the token defs in a muscle, just be ready to output it
- on command. Now possible via `symbols'. Fixes a memory leak.
-
- * src/output.c (token_definitions_output): New.
- (output_parser, header_output): Use it.
- * src/reader.c (symbols_save): Remove.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/bison.simple: Do not provide a default for YYSTYPE and
- YYLTYPE before the user's prologue. Otherwise it's hardly... a
- default.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Mid-rule actions are simply... ignored!
-
- * src/reader.c (readgram): Be sure to attach mid-rule actions to
- the empty-rule associated to the dummy symbol, not to the host
- rule.
- * tests/actions.at (Mid-rule actions): New.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Memory leak.
-
- * src/reader.c (reader): Free grammar.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Memory leak.
-
- * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
- since it allocates it for each state, although only one is needed.
- (allocate_storage): Do it here.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/options.h, src/options.c (create_long_option_table): Rename
- as...
- (long_option_table_new): this, with a clearer prototype.
- (percent_table): Remove, unused,
- * src/getargs.c (getargs): Adjust.

- ago.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c, src/reader.h (user_toknums): Remove.
- Adjust all users to use symbols[i]->user_token_number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.c, src/gram.h (sprec, sassoc): Remove.
- Adjust all users to use symbols[i]->prec or ->assoc.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-

- and rule_table.
- * src/reader.c (packsymbols): Fill this table.
- Drop sprec.
- * src/conflicts.c (resolve_sr_conflict): Adjust.
- * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
- single table.
- Use symbols[i]->tag instead of tags[i].
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
- In addition, put a comment in there, to replace...
- * tests/regression.at (%union and C comments): Remove.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Web2c Actions): Blindly move the actual
- output as expected output. The contents *seem* right to me, but I
- can't pretend reading perfectly parser tables... Nonetheless, all
- the other tests pass correctly, the table look OK, even though the
- presence of `$axiom' is to be noted: AFAICS it is useless (but
- harmless).
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Don't add the rule 0 if there were no
- rules read. In other words, add it _after_ having performed
- grammar sanity checks.
- Fixes the `tests/regression.at (Invalid input: 1)' Failure.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
- visible, and some states have now a different number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Bind the initial rule's lineno to that
- of the first rule.
- * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
- (Solved SR Conflicts): Adjust rule 0's line number.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- Fix the `GAWK Grammar' failure.
-
- * src/LR0.c (final_state): Initialize to -1 so that we do compute
- the reductions of the first state which was mistakenly confused
- with the final state because precisely final_state was initialized
- to 0.
- * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
- now noticed by Bison.
- * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
- have a reduction on $default.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/gram.c (ritem_print): Be sure to subtract 1 when displaying

-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/lalr.c (lookaheads_print): New.
- (lalr): Call it when --trace-flag.

- are dumped.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',

- (useful_production, useless_nonterminals): Likewise.
- (reduce_grammar_tables): Likewise, plus update nritems.
- * src/nullable.c (set_nullable): Likewise.
- * src/lalr.c (build_relations): Likewise.
- * tests/sets.at (Nullable): Adjust.
- Fortunately, now, the $axiom is no longer nullable.
-
-2001-12-29 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (generate_states): Use nritems, not nitems, nor using

-
- * src/output.c: Comment changes.
-
-2001-12-27 Paul Eggert <eggert@twinsun.com>
-
- * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
- cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
- Sparc, as they were causing more porting problems than the
- (minor) performance improvement was worth.
-
- Also, catch up with 1.31's YYSTD.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output_gram): Rely on nritems, not the
- 0-sentinel. See below.
- Use -1 as separator, not 0.
- * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
- Rely on -1 as separator in yyrhs, instead of 0.
- * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
- twice `Now at end of input', therefore there are two lines less to
- expect.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * tests/regression.at (Unresolved SR Conflicts):
- (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
- below.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (new_state): Recognize the final state by the fact it
- is reached by eoftoken.
- (insert_start_shifting_state, insert_eof_shifting_state)
- (insert_accepting_state, augment_automaton): Remove, since now
- these states are automatically computed from the initial state.
- (generate_states): Adjust.
- * src/print.c: When reporting a rule number to the user, substract
- 1, so that the axiom rule is rule 0, and the first user rule is 1.
- * src/reduce.c: Likewise.
- * src/print_graph.c (print_core): For the time being, just as for
- the report, depend upon --trace-flags to dump the full set of
- items.
- * src/reader.c (readgram): Once the grammar read, insert the rule
- 0: `$axiom: START-SYMBOL $'.
- * tests/set.at: Adjust: rule 0 is now displayed, and since the
- number of the states has changed (the final state is no longer
- necessarily the last), catch up.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- Try to make the use of the eoftoken valid. Given that its value
- is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
- is used instead of > 0 where appropriate, (ii), depend upon nritems
- instead of the 0-sentinel.
-
- * src/gram.h, src/gram.c (nritems): New.
- Expected to be duplication of nitems, but for the time being...
- * src/reader.c (packgram): Assert nritems and nitems are equal.
- * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
- * src/closure.c (print_closure, print_fderives): Likewise.

- reductions, then output the report anyway if requested, then die.
- * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
- * src/reader.c (eoftoken): New.
- (parse_token_decl): If the token being defined has value `0', it
- is the eoftoken.
- (packsymbols): No longer hack `tags' to insert `$' by hand.
- Be sure to preserve the value of the eoftoken.
- (reader): Make sure eoftoken is defined.
- Initialize nsyms to 0: now eoftoken is created just like the others.
- * src/print.c (print_grammar): Don't special case the eof token.
- * src/regression.at: Adjust: `$' has value 0, not -1, which was a
- lie anyway, albeit pleasant.
- * tests/calc.at: Exercise error messages with eoftoken.
- Change the grammar so that empty input is invalid.
- Adjust expectations.
- When yyungeting, be sure to use a valid yylloc: use last_yylloc.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * configure.in: Check the protos of strchr ans strspn.
- Replace strchr if needed.

- Use it to quote the TAGS outputs.
- * src/print_graph.c (print_state): Now errors are in red, and

- * src/reader.c (parse_braces): New, factoring...
- (copy_action, copy_guard): these two which are renamed as...

- As a voluntary consequence, using braces around guards is now
- mandatory.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/gram.h (rule_t): `guard' and `guard_line' are new members.
- * src/reader.c (symbol_list): `guard' and `guard_line' are new
- members.
- (symbol_list_new): Adjust.
- (copy_action): action_line is the first line, not the last.
- (copy_guard): Just as for actions, store the `action' only, not
- the switch/case/break flesh.
- Don't parse the user action that might follow the guard, let...
- (readgram): do it, i.e., now, there can be an action after a
- guard.
- In other words the guard is just explicitly optional.
- (packgram): Adjust.
- * src/output.c (guards_output): New.
- (output_parser): Call it when needed.
- (output): Also free the guard and attrs obstacks.
- * src/files.c, src/files.h (obstack_save): Remove.
- (output_files): Remove.
- As a result, if one needs the former `.act' file, using an
- appropriate skeleton which requires actions and guards is now
- required.
- * src/main.c (main): Adjust.
- * tests/semantic.at: New.
- * tests/regression.at: Use `input.y' as input file name.
- Avoid 8+3 problems by requiring input.c when the test needs the
- parser.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (symbol_list_new): Be sure to initialize all the
- fields.
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- All the hacks using a final pseudo state are now useless.
-

- (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it
- instead of lookaheadsp from the pseudo state (nstate + 1).
-
-2001-12-27 Akim Demaille <akim@epita.fr>
-
- * src/output.c (action_row, token_actions): Use a state_t instead
- of a integer, and nlookaheads instead of the following state's
- lookaheadsp.

-
- * src/conflicts.c (log_resolution, flush_shift)
- (resolve_sr_conflict, set_conflicts, solve_conflicts)
- (count_sr_conflicts, count_rr_conflicts, conflicts_output)
- (conflicts_print, print_reductions): Use a state_t instead of an
- integer when referring to a state.
- As much as possible, depend upon nlookaheads, instead of the
- `lookaheadsp' member of the following state (since lookaheads of
- successive states are successive, the difference between state n + 1
- and n served as the number of lookaheads for state n).
- * src/lalr.c (add_lookback_edge): Likewise.
- * src/print.c (print_core, print_actions, print_state)
- (print_results): Likewise.

-
- * src/output.c (prepare): Drop the muscle `ntbase' which
- duplicates ntokens.
- * src/bison.simple: Formatting/comment changes.
- Use YYNTOKENS only, which is documented, but not YYNTBASE, which
- is an undocumented synonym.
-
-2001-12-22 Akim Demaille <akim@epita.fr>
-
- * src/output.c (output_table_data): Change the prototype to use
- `int' for array ranges: some invocations do pass an int, not a
- short.
- Reported by Wayne Green.

-
-2001-12-15 Akim Demaille <akim@epita.fr>
-
- * src/nullable.c (set_nullable): Useless rules must be skipped,
- otherwise, since we range over their symbols, we might look at a
- nonterminal which no longer ``exists'', i.e., it is not counted in

- RHS's properly.
-
- * tests/torture.at (GNU AWK Grammar): New.
- * tests/sets.at (Nullable): New.
- * src/nullable.c (set_nullable): Instead of blindly looping over
- `ritems', loop over the rules, and then over their rhs's.
-
- Work around Autotest bugs.
-
- * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
- frame, because Autotest understand lines starting with a `+' as
- traces from the shell. Then, they are not processed properly.
- Admittedly an Autotest bug, but we don't have time to wait for
- Autotest to catch up.
- * tests/regression.at (Broken Closure): Adjust to the new table
- frames.
- Move to...
- * tests/sets.at: here.
-
-2001-12-13 Akim Demaille <akim@epita.fr>

-
-2001-12-13 Akim Demaille <akim@epita.fr>

- traces do: shifting the token EOF. Before EOF was treated as a
- nonterminal.
- * tests/regression.at: Adjust some tests.
- * src/print_graph.c (print_core): Complete the set of items via
- closure. The next-to-final and final states are still unsatisfying,
- but that's to be addressed elsewhere.
- No longer output the rule numbers, but do output the state number.
- A single loop for the shifts + gotos is enough, but picked a
- distinct color for each.
- (print_graph): Initialize and finalize closure.

-2001-12-13 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (readgram): Remove dead code, an strip useless

-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/state.h (shifts): Remove the `number' member: shifts are
- attached to state, hence no longer need to be labelled with a
- state number.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Now that states have a complete set of members, the linked list of
- shifts is useless: just fill directly the state's shifts member.
-
- * src/state.h (shifts): Remove the `next' member.
- * src/LR0.c (first_state, last_state): Remove.
- Adjust the callers.
- (augment_automaton): Don't look for the shifts that must be added
- a shift on EOF: it is those of the state we looked for! But now,
- since shifts are attached, it is no longer needed to looking
- merely by its id: its number.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Better variable locality.
- Remove an impossible branch: if there is a state corresponding to
- the start symbol being shifted, then there is shift for the start
- symbol from the initial state.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
- only when appropriate: when insert_start_shifting_state' is not
- invoked.
- * tests/regression.at (Rule Line Numbers): Adjust.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (augment_automaton): Now that all states have shifts,

-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.h (first_shift, first_reduction): Remove.
- * src/lalr.c: Don't use first_shift: find shifts through the
- states.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c: Attach shifts to states as soon as they are
- computed.

- state, just assert that the mapping was properly done.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/LR0.c (insert_start_shift): Rename as...
- (insert_start_shifting_state): this.
- (insert_eof_shifting_state, insert_accepting_state): New.
- (augment_automaton): Adjust.
- Better locality of the variables.
- When looking if the start_symbol is shifted from the initial
- state, using `while (... symbol != start_symbol ...)' sounds
- better than `while (... symbol < start_symbol ...)': If fail
- to see how the order between symbols could be relevant!
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/getargs.h: Don't declare `spec_name_prefix' and
- `spec_file_prefix', declared by src/files.h.
- * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
- * src/muscle_tab.c (muscle_init): Default prefix to NULL.
- * src/output.c (prepare): Adjust.
- * src/reader.c (symbols_output): Likewise.
- * src/vmsgetargs.c: Vaguely adjust, but who cares?
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/muscle_tab.c (muscle_init): NULL is a better default than
- `"0"'.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/reader.c (reader): Calling symbols_output once is enough.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- Now that states have a complete set of members, the linked list of
- reductions is useless: just fill directly the state's reductions
- member.
-
- * src/state.h (struct reductions): Remove member `number' and
- `next'.
- * src/LR0.c (first_reduction, last_reduction): Remove.
- (save_reductions): Don't link the new reductions, store them in
- this_state.
- * src/lalr.c (set_state_table): No need to attach reductions to
- states, it's already done.
- * src/output.c (output_actions): No longer free the shifts, then
- the reductions, then the states: free all the states and their
- members.
-
-2001-12-10 Akim Demaille <akim@epita.fr>
-
- * src/options.c (OPTN, DRTV, BOTH): New.
- (option_table): Use them.
-
- * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
- the job of system.h.
- * src/options.c: Don't include stdio.h and xalloc.h for the same
- reasons.
-
-2001-12-10 Akim Demaille <akim@epita.fr>

- * tests/Makefile.am: Adjust.
-
-2001-12-10 Akim Demaille <akim@epita.fr>

- (state_table): Be state_t **, not state_t *.
- * src/state.h (core, CORE_ALLOC): Rename as...
- (state_t, STATE_ALLOC): this.

-
- * src/print.c (print_core): If `trace_flag', then invoke closure
- before outputting the items of the state (print_core is no longer

-
- The location tracking mechanism is precious for parse error
- messages. Nevertheless, it is enabled only when `@n' is used in
- the grammar, which is a different issue (you can use it in error
- message, but not in the grammar per se). Therefore, there should
- be another means to enable it.
-
- * src/getargs.c (getargs): Support `--locations'.
- (usage): Report it.
- * src/getargs.h (locationsflag): Export it.
- * src/lex.c (percent_table): Support `%locations'.
- * src/reader.c (yylsp_needed): Remove this variable, now replaced
- with `locationsflag'.
- * doc/bison.texinfo: Document `--locations' and `%locations'.
- Sort the options.
- * tests/calc.m4: Test it.
-
- For regularity of the names, replace each
- (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
- (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
- In addition replace each `flag' with `_flag'.
-
-2000-10-02 Akim Demaille <akim@epita.fr>
-
- Also test parse error messages, including with YYERROR_VERBOSE.
-
- * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
- associative).
- Use it to check the computations.

- (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
- `--yyerror-verbose'.
- (_AT_CHECK_CALC): Adjust to this option.
- (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
-
-2000-10-02 Akim Demaille <akim@epita.fr>
-
- Test also `--verbose', `--defines' and `--name-prefix'. Testing
- the latter demonstrates a flaw in the handling of non debugging
- parsers introduced by myself on 2000-03-16: `#define yydebug 0'
- was used in order to simplify:
-
- #if YYDEBUG
- if (yydebug)
- {
- ...
- }
- #endif
-
- into
-
- if (yydebug)
- {
- ...
- }
-
- unfortunately this leads to a CPP conflict when
- `--name-prefix=foo' is used since it produces `#define yydebug
- foodebug'.
-
- * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
- (YYDPRINTF): New macro.
- Spread its use.
- * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
- the bison options.
- Also test `--verbose', `--defines' and `--name-prefix'.

- * src/output.c (output_parser): When the `$' is met, skip the end
- of its line.
- New variable, `number_of_dollar_signs', to check there's exactly
- one `$' in the parser skeleton.

-
- Use the more standard files `xalloc.h' and `xmalloc.c' instead of
- Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
- difficult and introduced a lot of core dump. It turns out that
- Bison used an implementation of `xmalloc' based on `calloc', and
- at various places it does depend upon the initialization to 0. I
- have not tried to isolate the pertinent places, and all the former
- calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
- someone should address this issue.
-
- * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

-
-2000-10-02 Akim Demaille <akim@epita.fr>
-
- `user_toknums' is output as a `short[]' in `output.c', while it is

+
+ Don't use IF_LINT in Bison sources.
+ It creates unnecessary differences between the sources that Bison
+ maintainers build and test (given that maintainers normally
+ configure with --enable-gcc-warnings) and the sources that Bison
+ users build. Instead, use PACIFY_CC, which doesn't. This change
+ fixes compiler warnings reported by Tys Lefering at
+ <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
+ * configure.ac: Don't AC_DEFINE lint regardless of the configure
+ options. This change affects imported gnulib sources, where
+ IF_LINT still appears and depends on lint.
+ * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
+ PACIFY_CC.
+ * src/system.h (IF_LINT): Remove cpp macro.
+ (PACIFY_CC): New cpp macro.
+
+2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Fix precedence for end token.
+ Since Bison 2.3b, which restored the ability of precedence
+ directives to assign user token numbers, doing so for user token
+ number 0 has produced an assertion failure.
+ * NEWS (2.5): Document fix.
+ * src/symtab.c (symbol_user_token_number_set): In the case of the
+ end token, don't decrement ntokens if it was never incremented.
+ * tests/regression.at (Token number in precedence declaration):
+ Extend.
+
+2011-05-01 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Pacify -DGNULIB_POSIXCHECK.

+ * src/location.c (boundary_set_from_string)
+ * src/output.c (output_skeleton)
+ * src/parse-gram.y (prologue_declaration)
+ * src/scan-gram.l (handle_syncline)
+ * src/symtab.c (symbol_new): Use mbschr and mbsrchr instead of
+ strchr and strrchr. In the cases of command-line options, file
+ names, and thus locations, functionality may be improved. In the
+ case of symbol names, there should be no functional difference as
+ all characters are ASCII, so the intended benefit is just warning
+ suppression.

+ This prevents gcc 4.6.0's -Wunused-but-set-variable from warning

+
+ doc: clean up naming of various Bison files.
+ The Bison manual's names for various files associated with a Bison
+ parser has devolved into inconsistency. This patch makes the
+ naming consistent for the most important files. First, it chooses
+ "grammar file" over "input file". The former appears to be more
+ traditional in the Bison manual, and Bison has other input
+ files (skeletons). Second, it chooses "parser implementation
+ file" over names like "parser file", "parser source file", "parser
+ source code file", and "parser output file". The new name makes
+ it clearer where Bison generates the main parser implementation,
+ and it is easily distinguishable from "parser header file".
+ * doc/bison.texinfo: Implement throughout.
+
+2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
+
+ doc: give credit to more of Bison's developers.
+ * doc/bison.texinfo (Introduction): Don't imply that only Robert
+ Corbett, Richard Stallman, and Wilfred Hansen have contributed to
+ Bison. However, I don't have time to write a full history, so
+ just point readers to THANKS and ChangeLog.
+
+2011-02-06 Joel E. Denny <joeldenny@joeldenny.org>
+
+ doc: document experimental features better.
+ * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
+ LR(1) are experimental. Mention Java. Normally experimental
+ features probably shouldn't be mentioned in the introduction.
+ However, if Bison's limitations to LALR(1), C, and C++ are so
+ important that they should be mentioned here, then it's important
+ to point out that Bison is beginning to escape those limitations.
+ Moreover, these particular experimental features have very little
+ chance of being removed.
+ * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
+ experimental.

+
+ Do not allow identifiers that start with a dash.
+ This cleans up our previous fixes for a bug whereby Bison
+ discarded `.field' in `$-1.field'. The previous fixes were less
+ restrictive about where a dash could appear in an identifier, but
+ the restrictions were hard to explain. That bug was reported and
+ this final fix was originally suggested by Paul Hilfinger. This
+ also fixes a remaining bug reported by Paul Eggert whereby Bison
+ parses `%token ID -123' as `%token ID - 123' and handles `-' as an
+ identifier. Now, `-' cannot be an identifier. Discussed in
+ threads beginning at
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00000.html>,
+ <http://lists.gnu.org/archive/html/bug-bison/2011-01/msg00004.html>.
+ * NEWS (2.5): Update entry describing the dash extension to
+ grammar symbol names. Also, move that entry before the named
+ references entry because the latter mentions the former.
+ * doc/bison.texinfo (Symbol): Update documentation for symbol
+ names. As suggested by Paul Eggert, mention the effect of periods
+ and dashes on named references.
+ (Decl Summary): Update documentation for unquoted %define values,
+ which, as a side effect, can no longer start with dashes either.
+ * src/scan-code.l (id): Implement.
+ * src/scan-gram.l (id): Implement.
+ * tests/actions.at (Exotic Dollars): Extend test group to exercise
+ bug reported by Paul Hilfinger.
+ * tests/input.at (Symbols): Update test group, and extend to

+
+2011-01-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix minor problems encountered by a fresh bootstrap.
+ * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
+ as they confuse xgettext, which tries to parse them as C character
+ constants in a preprocessor directive.
+ * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as
+ that expression might not promote to int on some platforms.
+ * src/parse-gram.c, src/parse-gram.h: Regenerate.
+
+2011-01-09 Joel E. Denny <joeldenny@joeldenny.org>
+
+ Improve error messages for `$' or `@' followed by `.' or `-'.
+ Previously, for this special case of an invalid reference, the
+ usual "symbol not found in production:" was printed. However,
+ because the symbol name was parsed as the empty string, that
+ message was followed immediately by a newline instead of a symbol
+ name. In reality, this is a syntax error, so the reference is
+ invalid regardless of the symbols actually appearing in the
+ production. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2011-01/msg00012.html>.
+ * src/scan-code.l (parse_ref): Report the above case as a syntax
+ error. Other than that, continue to handle this case like any
+ other invalid reference that Bison manages to parse because
+ "possibly meant" messages can still be helpful to the user.
+ * tests/named-refs.at ($ or @ followed by . or -): New test group.
+
+2011-01-08 Joel E. Denny <joeldenny@joeldenny.org>

+
+ parse.lac: implement exploratory stack reallocations.
+ * data/yacc.c: Rename %define variable parse.lac.es-capacity to
+ parse.lac.es-capacity-initial. Accept parse.lac.memory-trace
+ with values of "failures" (default) or "full".
+ (b4_declare_parser_state_variables): Add yyesa, yyes, and
+ yyes_capacity variables.
+ (YYSTACK_USE_ALLOCA): Ignore it if LAC requested.
+ (YYSTACK_ALLOC, YYSTACK_FREE, YYSTACK_ALLOC_MAXIMUM): Define if
+ LAC requested.
+ (YYCOPY_NEEDED): New cpp macro.
+ (YYCOPY): Define if LAC requested.
+ (yy_lac_stack_realloc): New function implementing stack
+ reallocations. Use YYMAXDEPTH for maximum stack size given that
+ the stack should never need to grow larger than the main state
+ stack needs to grow without LAC.
+ (YY_LAC_ESTABLISH): Update yy_lac invocation.
+ (yy_lac): Add arguments for exploratory stack memory data
+ recorded in the main parser. Invoke yy_lac_stack_realloc when
+ reallocation is necessary.
+ (yysyntax_error): Add the same new arguments and pass them to
+ yy_lac.
+ (yypstate_delete): Free yyes if necessary.
+ (yyesa, yyes, yyes_capacity): #define these to yypstate members
+ in the case of push parsing.
+ (yyparse, yypush_parse): Initialize yyes and yyes_capacity.
+ Update yysyntax_error invocations. At yyreturn, free yyes if
+ necessary.
+ * src/parse-gram.y: %define parse.lac full.
+ * tests/input.at (LAC: errors for %define): Extend for
+ parse.lac-memory-trace.
+ * tests/regression.at (LAC: Exploratory stack): Extend to check
+ that stack reallocs happen when expected.
+ (LAC: Memory exhaustion): Update to use YYMAXDEPTH and
+ parse.lac.es-capacity-initial.
+
+2010-12-11 Joel E. Denny <joeldenny@joeldenny.org>
+
+ parse.lac: implement as %define variable.
+ LAC = lookahead correction. See discussion at
+ <http://lists.gnu.org/archive/html/bison-patches/2009-09/msg00034.html>.
+ However, one point there must be corrected: because of %nonassoc,
+ LAC is *not* always redundant for lr.type=canonical-lr.
+ * data/yacc.c: Accept values of "none" (default) or "full" for
+ parse.lac. Accept %define parse.lac.es-capacity to specify
+ capacity of LAC's temporary exploratory stack. It defaults to 20
+ and, for now, will not grow dynamically.
+ (b4_lac_flag, b4_lac_if): New m4 macros. Evaluate as true for
+ parse.lac!=none.
+ (YYBACKUP): Invoke YY_LAC_DISCARD.
+ (YY_LAC_ESTABLISH, YY_LAC_DISCARD): New cpp macros that invoke
+ yy_lac and track when it needs to be invoked
+ (yy_lac): New function that, given the current stack, determines
+ whether a token can eventually be shifted. Return status mimics
+ yyparse return status.
+ (yysyntax_error): Change yystate argument to yyssp so stack top
+ can be passed to yy_lac. If LAC is requested, build expected
+ token list by invoking yy_lac for every token instead of just
+ checking the current state for lookaheads. Return 2 if yy_lac
+ exhausts memory.
+ (yyparse, yypush_parse): Use local variable yy_lac_established and
+ cpp macros YY_LAC_ESTABLISH and YY_LAC_DISCARD to implement LAC.
+ Update yysyntax_error invocation. Add yyexhaustedlab code if LAC
+ is requested.
+ * tests/conflicts.at (%nonassoc and eof): Extend to check the
+ effect of each of -Dlr.type=canonical-lr and -Dparse.lac=full.
+ (parse.error=verbose and consistent errors): Likewise.
+ (LAC: %nonassoc requires splitting canonical LR states): New test
+ group demonstrating how LAC can fix canonical LR.
+ * tests/input.at (LAC: Errors for %define): New test group.
+ * tests/regression.at (LAC: Exploratory stack): New test group.
+ (LAC: Memory exhaustion): New test group.

+ build: use gnulib's new bootstrap_sync option.
+ Now, whenever we update bison's copy of gnulib, bootstrap will

+ * gnulib: Update to latest so bootstrap is in sync now.
+
+2010-11-07 Joel E. Denny <joeldenny@joeldenny.org>
+
+ yysyntax_error: fix for consistent error with lookahead.
+ * NEWS (2.5): Document.
+ * data/yacc.c (yysyntax_error): In a verbose syntax error
+ message while in a consistent state with a default action (which
+ must be an error action given that yysyntax_error is being
+ invoked), continue to drop the expected token list, but don't
+ drop the unexpected token unless there actually is no lookahead.
+ Moreover, handle that internally instead of returning 1 to tell
+ the caller to do it. With that meaning of 1 gone, renumber
+ return codes more usefully.
+ (yyparse, yypush_parse): Update yysyntax_error usage. Most
+ importantly, set yytoken to YYEMPTY when there's no lookahead.
+ * data/glr.c (yyreportSyntaxError): As in yacc.c, don't drop the
+ unexpected token unless there actually is no lookahead.
+ * data/lalr1.cc (yy::parser::parse): If there's no lookahead,
+ pass yyempty_ not yyla.type to yysyntax_error_.
+ (yy::parser::yysyntax_error_): Again, don't drop the unexpected
+ token unless there actually is no lookahead.
+ * data/lalr1.java (YYParser::parse): If there's no lookahead,
+ set yytoken to yyempty_ before invoking yysyntax_error.
+ (YYParser::yysyntax_error): Again, don't drop the unexpected
+ token unless there actually is no lookahead.
+ * tests/conflicts.at (parse.error=verbose and consistent
+ errors): Extend test group to further reveal how the previous
+ use of the simple "syntax error" message was too general. Test
+ yacc.c, glr.c, lalr1.cc, and lalr1.java. No longer an expected
+ failure.
+ * tests/java.at (AT_JAVA_COMPILE, AT_JAVA_PARSER_CHECK): Move
+ to...
+ * tests/local.at: ... here.
+ (_AT_BISON_OPTION_PUSHDEFS): Push AT_SKEL_JAVA_IF definition.
+ (AT_BISON_OPTION_POPDEFS): Pop it.
+ (AT_FULL_COMPILE): Extend to handle Java.

+ portability: fix several issues with M4 subprocess.
+
+ M4's output pipe was not being drained upon fatal errors during
+ scan_skel. As a result, broken-pipe messages from M4 were seen
+ on at least AIX, HP-UX, Solaris, and RHEL4, and this caused a
+ failure in the test suite. The problem was that, on platforms
+ where the default disposition for SIGPIPE is ignore instead of
+ terminate, M4 sometimes saw fwrite fail with errno=EPIPE and
+ then reported it. However, there's some sort of race condition,
+ because the new test group occasionally succeeded.
+ Reported by Albert Chin at
+ <http://lists.gnu.org/archive/html/bug-bison/2010-02/msg00004.html>.

+ To attempt to solve both of these problems, switch to gnulib's

+ way, clean up file name conflict handling, which was affected by
+ the broken-pipe problem before the switch.

+2010-01-15 Joel E. Denny <jdenny@clemson.edu>
+
+ Thank the developer of the initial push parser implementation.
+ This unfortunate oversight is several years old.
+ * THANKS (Odd Arild Olsen): Add.

+
+ Fix some comments concerning LR(0) versus LALR(1).
+
+ Stop equating LR(0) with nondeterminism and LALR(1) with
+ determinism. That is, if all states are consistent, then LR(0)
+ tables are deterministic. On the other hand, LALR(1) tables
+ might be nondeterministic before conflict resolution, and GLR
+ permits LALR(1) tables to remain nondeterministic.
+ * src/LR0.c, src/LR0.h: Here.
+ * src/lalr.c, src/lalr.h: Here.
+ * src/main.c (main): Here.
+ * src/state.c, src/state.h: Here.
+
+ * src/ielr.h (ielr): In preconditions, expect LR(0) not LALR(1)
+ parser tables.

+ portability: `<' and `>' are not always defined on addresses.
+ Specifically, don't sort objects by their memory addresses when
+ they're not allocated in the same array or other object. Though

+2009-12-20 Joel E. Denny <jdenny@clemson.edu>
+
+ Fix handling of yychar manipulation in user semantic actions.
+ The problem was that yacc.c didn't always update the yychar
+ translation afterwards. However, other skeletons appear to be
+ fine. glr.c appears to already translate yychar before every
+ use. lalr1.cc does not define yychar and does not document its
+ replacement, yyla, for users. It does provide yyclearin, but
+ that does not manipulate yyla and thus requires no translation
+ update. In lalr1.java, yychar is out of scope during semantic
+ actions.
+ * NEWS (2.5): Document.
+ * data/yacc.c (YYBACKUP): Don't bother translating yychar into
+ yytoken here.
+ (yyparse, yypush_parse): Instead, translate before every use of
+ yytoken, and add comments explaining this approach.
+ * tests/actions.at (Destroying lookahead assigned by semantic
+ action): New test group checking that translation happens before
+ lookahead destructor calls at parser return. Previously,
+ incorrect destructors were called.
+ * tests/conflicts.at (parse.error=verbose and consistent
+ errors): New test group checking that translation happens at
+ syntax error detection before the associated verbose error
+ message and the associated lookahead destructor calls. While
+ the destructor call is fixed by this patch, the verbose error
+ message is currently incorrect due to another bug (see
+ comments in test group), so this is an expected failure for now.

+
+ yysyntax_error: avoid duplicate lookahead collection.
+ Except when memory reallocation is required, this change
+ eliminates the need to invoke yysyntax_error twice and thus to
+ repeat the collection of lookaheads. It also prepares for
+ future extensions that will make those repetitions more
+ expensive and that will require additional memory management in
+ yysyntax_error. Finally, it fixes an obscure bug already
+ exercised in the test suite.
+ * data/yacc.c (yysyntax_error): Add arguments for message
+ buffer variables stored in the parser. Instead of size, return
+ status similar to yyparse status but indicating success of
+ message creation. Other than the actual reallocation of the
+ message buffer, import and clean up memory management code
+ from...
+ (yyparse, yypush_parse): ... here.
+ * tests/regression.at (parse.error=verbose overflow): No longer

+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):

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

+ Finer input type for yytranslate.
+ This patch is debatable: the tradition expects yylex to return an int
+ which happens to correspond to token_number (which is an enum). This
+ allows for instance to return characters (such as '*' etc.). But this

+ parameterized constructors do not work well in C++ (unless the
+ parameter also appears as an argument, which is not acceptable),
+ hence the use of a function instead of a constructor.

+ Change the handling of the symbols in the skeletons.
+ Before we were using tables which lines were the symbols and which
+ columns were things like number, tag, type-name etc. It is was
+ difficult to extend: each time a column was added, all the numbers had
+ to be updated (you asked for colon $2, not for "tag"). Also, it was
+ hard to filter these tables when only a subset of the symbols (say the
+ tokens, or the nterms, or the tokens that have and external number
+ *and* a type-name) was of interest.
+
+ Now instead of monolithic tables, we define one macro per cell. For
+ instance "b4_symbol(0, tag)" is a macro name which contents is
+ self-decriptive. The macro "b4_symbol" provides easier access to
+ these cells.

+ Unfortunately this uncovered a bug in the C++ parser itself: the

+ then the value of the std::string was correctly taken (i.e., the
+ lookahead was now an empty string), but std::string structure itself
+ was not reclaimed.
+
+ This is now done in variant::build(other&) (which is used to take the
+ value of the lookahead): other is not only stolen from its value, it
+ is also destroyed. This incurs a new performance penalty of a few

+
+ Fuse the three stacks into a single one.
+
+ In order to make it easy to perform benchmarks to ensure that
+ there are no performance loss, lalr1.cc is forked into
+ lalr1-fusion.cc. Eventually, lalr1-fusion.cc will replace
+ lalr1.cc.
+
+ Meanwhile, to make sure that lalr1-fusion.cc is correctly
+ exercized by the test suite, the user must install a symbolic link
+ from lalr1.cc to it.
+
+ Instead of having three stacks (state, value, location), use a
+ stack of triples. This considerably simplifies the code (and it
+ will be easier not to require locations as currently does the C++
+ parser), and also gives a 10% speedup according to
+ etc/bench (probably mainly since memory allocation is done once
+ instead of three times).
+
+ Another motivation is to make it easier to destruct properly
+ semantic values: now that they are bound to their state (hence
+ symbol type) it will be easier to call the appropriate destructor.
+
+ These changes should probably benefit the C parser too.
+
+ * data/lalr1.cc: Copy as...
+ * data/lalr1-fusion.cc: this new file.
+ (b4_rhs_value, b4_rhs_location): New definitions overriding those

+ (parser::yynewstate): Change the semantics: instead of arriving to

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

+ the above macros.
+ * data/lalr1.cc (b4_namespace): Likewise.

+ * doc/bison.texinfo (Decl Summary): Move `%define push_pull' entry

+ explains it more completely in the case of C++.
+ (C++ Bison Interface): Mention `%define namespace' instead of
+ %name-prefix.
+ (Table of Symbols): Remove the `%define push_pull' entry. The %define
+ entry suffices.

+2007-10-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix some error-reporting macro bugs.
+ * data/bison.m4 (b4_cat): New.
+ (b4_error, b4_error_at): Use b4_cat to send error directives directly

+ comments and add examples.
+ (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and
+ add examples.
+ (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately
+ after printing the error directive so that M4 doesn't report subsequent
+ problems that are induced by this problem.
+ * src/scan-skel.l: Recognize @` digraph outside of directive arguments
+ instead of just in them. Recognize @\n in both places. Both expand to
+ the empty string. Needed by b4_cat.
+ * tests/skeletons.at (Complaining during macro argument expansion):
+ New test case.
+ (Fatal errors make M4 exit immediately): New test case.
+
+2007-10-04 Joel E. Denny <jdenny@ces.clemson.edu>

+
+ Replace `%push-parser' and `%push-pull-parser' with

+ parsing requests here...
+ * data/yacc.c: ... hack this to switch to push.c any time
+ b4_use_push_pull_flag or the %define variable push_pull is set. This
+ will go away when we mv push.c yacc.c.
+ * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
+ push parsing is not supported since unused %define variables are

+
+2007-08-03 Joel E. Denny <jdenny@ces.clemson.edu>

+
+2007-07-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/muscle_tab.c (muscle_percent_define_flag_if): In order to
+ determine whether this function has already complained about an invalid
+ value for a %define boolean variable, don't check whether Bison has
+ ever examined the value. As written, the check was a tautology.
+ Instead, record and check for this complaint using a separate muscle.

+ * tests/testsuite.at: Include push.at.
+ * test/push.at: New.
+ (Push Parsing: Memory Leak for Early Deletion): New test case.
+
+2007-07-17 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Improve handling of multiple S/R conflicts in the same state and of S/R
+ conflicts involving multiple reductions.
+ * src/conflicts.c (resolve_sr_conflict): Don't assign the error action
+ set for a state here or Bison will abort if it is reassigned on a
+ later conflicted reduction in the same state.
+ Similarly, don't finalize and assign the solved conflicts report here
+ or it will be lost if it is reassigned on a later conflicted reduction
+ in the same state.
+ (set_conflicts): Instead, assign them both here after all S/R conflicts
+ in the state have been fully examined.
+ * src/print.c (shift_set): Rename to...
+ (no_reduce_set): ... this.
+ (print_reductions): Update for rename, and add %nonassoc error action
+ tokens to no_reduce_set so that, when printing the first remaining
+ reduction on an error action token, the reduction is enclosed in
+ brackets.
+ (print_results): Update for rename.
+ * tests/conflicts.at (Solved conflicts report for multiple reductions
+ in a state): New test case.
+ (%nonassoc error actions for multiple reductions in a state): New test
+ case.
+
+ * src/main.c (main): Don't depend on C99 features.
+
+2007-07-16 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * build-aux/.cvsignore: Add compile.
+ * lib/.cvsignore: Add charset.alias, ref-add.sed, ref-del.sed, and
+ uniwidth.
+
+2007-07-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * bootstrap (slurp): Create target directories that don't exist.
+ Specifically, we need lib/uniwidth/ because of recent Gnulib changes.
+
+2007-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * LR0.c (new_itemsets): Fix wording in comments: say item index rather
+ than item number.
+ * closure.c (closure): Likewise.
+ * state.h (reductions): Comment sorting of rules.
+ (state): Comment sorting of items.
+
+2007-07-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix C++ test cases after recent Gnulib changes. Discussed starting at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-07/msg00000.html>.
+ * examples/calc++/Makefile.am (DEFAULT_INCLUDES): Override Automake's
+ definition in order to avoid Gnulib headers since we don't use config.h
+ here.
+ * tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use AT_DATA_GRAMMAR
+ rather than AT_DATA so that config.h is included.
+
+2007-07-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yy_yypstack, yypstates, yypdumpstack): Use YYFPRINTF
+ instead of fprintf. Guard these functions with #if YYDEBUG instead of
+ #ifdef YYDEBUG for consistency with all other uses of YYDEBUG in Bison
+ and so that YYFPRINTF is guaranteed to be defined here.
+
+2007-05-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/muscle_tab.c (muscle_percent_define_invalid_value): Replace
+ with...
+ (muscle_percent_define_check_values): ... this more helpful function.
+ Again, it's not used yet, but it will be.
+ * src/muscle_tab.h: Likewise.
+
+ Improve some comments in parser table construction.
+ * src/LR0.c (new_itemsets): Explain sorting of itemset and kernel_base.
+ (generate_states): Don't mention ruleset, which is internal to closure.
+ * src/closure.c (closure): Explain sorting of core and itemset, which
+ is required for this function to behave correctly.
+ * src/closure.h (closure): Mention sorting.
+
+2007-05-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/lalr.c (state_lookahead_tokens_count): For code readability,
+ move the check for disabled transitions to an aver since conflict
+ resolution hasn't happened yet.
+
+ * src/lalr.c (state_lookahead_tokens_count): Remove the check that
+ labels a state as inconsistent just because it has error transitions.
+ The original form of this check appeared in revision 1.1 of lalr.c,
+ which was committed on 1991-12-21. Now (at least), changing the
+ consistency label on such a state appears to have no useful effect in
+ any of the places it is examined, which I enumerate below. The key
+ point to understanding each item in this enumeration is that a state
+ with an error transition is labelled consistent in the first place only
+ if it has no rules, so the check cannot matter for states that have
+ rules. (1) Labelling a state as inconsistent will cause set_conflicts
+ to try to identify its conflicts, and a state must have *rules* to have
+ conflicts. (2) Labelling a state as inconsistent will affect how
+ action_row sets the default *rule* for the state. (3) Labelling a
+ state as inconsistent will cause build_relations to add lookback edges
+ to *rules* in that state.
+ * src/state.h (struct state): Word the comment for member consistent
+ more carefully.
+

+2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up.
+ * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
+ at_directive_argv arguments so these no longer have to be global
+ variables. Also, update the implementation for the following changes.
+ (fail_for_at_directive_too_many_args,
+ fail_for_at_directive_too_few_args): Add at_directive_name argument.
+ (at_directive_name): Remove as at_directive_argv[0] will be used for
+ this now.
+ (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
+ for the directive name.
+ (at_directive_argc, at_directive_argv): Make these local within
+ skel_lex instead of global.
+ (INITIAL): Update directive start action for above changes.
+ (SC_AT_DIRECTIVE_ARG): Rename to...
+ (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
+ (SC_AT_DIRECTIVE_SKIP_WS): Update.
+ (scan_skel): Move yylex_destroy to...

+ * tests/skeletons.at (installed skeleton file name): Rename to...
+ (installed skeleton file names): ... this.
+
+2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * ChangeLog: For changes in doc/bison.texinfo, consistently reference
+ node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
+ Summary" not "Directives".
+ * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
+ %code entry in "Decl Summary" rather than the one in "Table of Symbols"
+ since the former is now the more complete one.
+ (Prologue Alternatives): Likewise and do the same for %defines.
+ (Table of Symbols): Add summary of %code, add summary of %define, and
+ move full %code documentation to...
+ (Decl Summary): ... here for consistency with other entries in these
+ sections.
+ Move %define entry in order to keep this list alphabetized.
+ Reword %define entry a little to put less emphasis on the skeleton
+ concept, which most users shouldn't have to think about.
+
+2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to recent gnulib changes.
+ * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
+ Add string.h, string_.h, unistd_.h, wchar_.h.
+ * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
+ * src/system.h: Don't include <stpcpy.h>; this is now done by
+ <string.h>.
+
+2007-01-23 Paolo Bonzini <bonzini@gnu.org>

+ * doc/bison.texinfo (Decl Summary): Document in %skeleton entry.
+ (Bison Options): Document in --skeleton entry.
+ * src/output.c (output_skeleton): Use strncpy rather than strcpy since
+ full_skeleton can't necessarily hold all of pkgdatadir.
+ If the specified skeleton file name contains a `/', don't prepend

+
+ Clean up %define and %code implementation in M4 some. Most
+ importantly, rename all related macros to be in the b4_percent_define
+ and b4_percent_code namespaces. Also, complete support for `.' in
+ %define variable names and %code qualifiers.
+ * data/bison.m4 (b4_check_user_names): Check for special
+ "SKELETON-NAMESPACE(name)" macros instead of using two nested
+ m4_foreach loops.
+ (b4_get_percent_define, b4_get_percent_code): Rename to...
+ (b4_percent_define_get, b4_percent_code_get): ... these.
+ Extend documentation with examples.
+ For SKELETON-NAMESPACE (as documented for b4_check_user_names), use
+ b4_percent_define_skeleton_variables and
+ b4_percent_code_skeleton_qualifiers.
+ Expect any value for the %define variable `foo' to be stored in the
+ macro named `b4_percent_define(foo)'; expect any %code blocks for the
+ qualifier `foo' to be stored in a macro named `b4_percent_code(foo)';
+ expect any unqualified %code blocks to be stored in a macro named
+ `b4_percent_code_unqualified'.
+ Use m4_indir so that %define variable names and %code qualifiers can
+ contain `.', which is allowed by the grammar parser.
+ (b4_percent_define_default): New macro to set a default value for a
+ %define variable.
+ (m4_wrap): Update wrapped code, and fix some underquoting.
+ (b4_check_user_names_wrap): Update and define outside the m4_wrap.
+ Expect grammar uses of %define variables and %code qualifiers to be
+ defined in b4_percent_define_user_variables and
+ b4_percent_code_user_qualifiers.
+ * data/c++.m4: Use b4_percent_define_default rather than
+ m4_define_default. Fix some underquoting. Skeleton usage of %define
+ variable define_location_comparison now implies skeleton usage of
+ %define variable filename_type.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
+ data/push.c, data/yacc.c: Update macro names.

+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to
+ run parsers in all tests so that Valgrind is invoked during
+ maintainer-check-valgrind.
+ (Duplicate representation of merged trees): Free all semantic values.
+ (Duplicated user destructor for lookahead): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a

+ (Exploding the Stack Size with Malloc): Likewise.
+
+2007-01-09 Joel E. Denny <jdenny@ces.clemson.edu>

+
+ Simplify union and prologue handling, and escape union and lex/parse

+ * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
+ values to the empty string since these are no longer guaranteed
+ initialized by the front-end.
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add

+ * src/files.c, src/files.h (pre_prologue_obstack,
+ post_prologue_obstack): Remove.
+ * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header

+ with digraphs. This fixes lex params and parse params.
+ * src/muscle_tab.h (muscle_pair_list_grow): Update comments.
+ * src/output.c (prepare): Remove muscle insertion of the prologues.
+ (output): Remove freeing of pre_prologue_obstack and
+ post_prologue_obstack.
+ * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
+ than prologue_augment for prologue parsing so you don't need prologue
+ obstacks.
+ (grammar_declaration): For %union RHS, use `braceless' instead of
+ "{...}" so that braces are already stripped and code is escaped with

+ * src/reader.c (prologue_augment): Remove.
+ (reader): Remove initialization of pre_prologue_obstack and

+ * NEWS (2.3a+): Add entry for the change to %define. Update entry for

+ (C++ Location Values): Update %define uses.
+ (Calc++ Parser Interface): Likewise.
+ (Calc++ Parser): Likewise, and update `%code requires' uses.
+ (Table of Symbols): Update %code documentation.
+ * src/parse-gram.y (prologue_declaration): For %define variables, use

+
+2007-01-08 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Instead of having skeletons declare all valid %define variables and
+ %code qualifiers, provide macros that retrieve the associated values
+ and build these lists automatically. Thus Bison will now warn when a
+ variable or qualifier is not used by the skeleton in the current
+ invocation regardless of whether it might sometimes be used by that
+ skeleton in other invocations. Also, move all %define value macros to
+ the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
+ form, which is replaced by %code.
+ * data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
+ (b4_check_user_names): ... this, and change the series of valid name
+ arguments to a single list argument for names used in the skeleton
+ similar to the existing list argument for names used in the grammar.
+ Warn instead of complaining.
+ (b4_get_percent_define, b4_get_percent_code): New to retrieve %define
+ values and %code code, to format %code code properly, and to build
+ lists of all %define variables and %code qualifiers used in the
+ skeleton: b4_skeleton_percent_define_variables and
+ b4_skeleton_percent_code_qualifiers.
+ (b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
+ Remove, and...
+ (m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
+ the skeleton names lists can finish building first. In place of
+ b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
+ expect the lists b4_user_percent_define_variables and
+ b4_user_percent_code_qualifiers.
+ * data/c++.m4: Where setting default values for b4_parser_class_name,
+ b4_location_type, b4_filename_type, b4_namespace, and
+ b4_define_location_comparison, update their names to the
+ b4_percent_define_ namespace.
+ * data/glr.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
+ (b4_parser_class_name, b4_namespace): Define these using
+ b4_get_percent_define for parser_class_name and namespace.
+ * data/location.cc: Use b4_get_percent_define.
+ * data/push.c: Don't use b4_check_percent_define_variables and
+ b4_check_percent_code_qualifiers. Use b4_get_percent_code.
+ * data/yacc.c: Likewise, and don't call m4_exit in
+ b4_use_push_for_pull_if or m4_wrap code will never execute.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
+ Rename to...
+ (muscle_grow_user_name_list): ... this for consistency with the
+ terminology used in bison.m4.
+ * src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
+ %define variable names, and rename muscle used_percent_define_variables
+ to user_percent_define_variables.
+ (grammar_declaration): Rename muscle used_percent_code_qualifiers to
+ user_percent_code_qualifiers.
+ (content): Remove.
+ (content.opt): Replace content RHS with STRING RHS so %define "NAME"
+ {CODE} form is no longer accepted.
+ * tests/input.at (Reject bad %code qualifiers): Rename to...
+ (Reject unused %code qualifiers): ... this, and update test output.
+ (%define error): Update test output.
+
+2007-01-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Check for unrecognized %define variables similar to checking for

+ * data/bison.m4 (b4_check_for_unrecognized_names): New macro that
+ generalizes...
+ (b4_check_percent_code_qualifiers): ... this, which now wraps it.
+ (b4_check_percent_define_variables): New, also wraps it.
+ * data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
+ variables using b4_check_percent_define_variables.
+ * data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
+ all those exercised in the test suite and all those listed in the
+ `Default values' section of c++.m4. Are there others?
+ * data/push.c, data/yacc.c: Declare no valid %define variables.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
+ similar to muscle_find, but it works even when the muscle stores a

+ (muscle_grow_used_name_list): New function for constructing the used
+ name list muscles that b4_check_for_unrecognized_names requires.
+ * src/parse-gram.y (prologue_declaration): Warn if a variable is

+ muscle with muscle_grow_used_name_list.
+ (grammar_declaration): Abbreviate %code code with
+ muscle_grow_used_name_list.
+ * tests/input.at (%define errors): New.
+
+2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Provide warn_at, complain_at, and fatal_at function callbacks to the
+ skeletons, and use this for %code qualifier complaints.
+ * data/bison.m4 (b4_error_at): New, invoked by...
+ (b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
+ the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
+ @fatal_at(...@) directives.
+ (b4_check_percent_code_qualifiers): Rewrite to expect locations for
+ qualifiers in b4_used_percent_code_qualifiers and to use
+ b4_complain_at.
+ * src/location.c, src/location.h (boundary_set_from_string): New global
+ function.
+ * src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global

+ (SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
+ here; these newlines are in the input but not the output file.
+ (SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
+ (at_directive_perform): ... this new static function, and add handling
+ of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
+ directives.
+ * tests/input.at (Reject bad %code qualifiers): Update test output with
+ locations and extend.
+
+ * tests/output.at (Output file name: [, Output file name: ]): Remove
+ bogus comment about these tests failing.
+
+2007-01-06 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up b4_check_percent_code_qualifiers a little.
+ * data/bison.m4 (b4_check_percent_code_qualifiers): Expect qualifiers
+ in b4_used_percent_code_qualifiers to be double-M4-quoted. Rewrite
+ documentation and add examples.
+ * src/parse-gram.y (grammar_declaration): Double-M4-quote those
+ qualifiers here.
+
+2007-01-05 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't use m4_divert since it makes m4_divert_push and m4_divert_pop
+ unreliable -- especially when they're hidden inside another macro.
+ * data/bison.m4, data/c++-skel.m4, data/c++.m4, data/c-skel.m4,
+ data/c.m4: Remove m4_divert(-1).
+ * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc,
+ data/push.c, data/yacc.c: Likewise, and replace m4_divert(0) with
+ m4_divert_push(0) and m4_divert_pop(0).
+ * src/output.c (output_skeleton): Don't add an m4_divert_push(0) and
+ an m4_wrap([m4_divert_pop(0)]) to the M4. Diversion -1, which is
+ pushed and popped by m4sugar, should be first on the stack.
+
+ Provide warn, complain, and fatal function callbacks to the skeletons.
+ This provides more flexibility than m4_fatal, improves the error
+ message format, and captures messages for translation. Discussed
+ starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00063.html>.
+ * data/bison.m4 (b4_error): New, invoked by...
+ (b4_warn, b4_complain, b4_fatal): ... these new macros to wrap the
+ skeleton scanner's new @warn(...@), @complain(...@), and @fatal(...@)
+ directives. Because these M4 macros might be called when the current
+ diversion is -1 or 0, m4_divert_push and m4_divert_pop is used; thus
+ the previous removal of uses of m4_divert, which caused trouble.
+ (b4_check_percent_code_qualifiers): Use b4_complain instead of
+ m4_fatal to report unrecognized %code qualifiers.
+ * data/c++-skel.m4: Use b4_complain instead of m4_fatal to report C++
+ push parser requests.
+ * data/glr.c: Use b4_complain instead of m4_fatal to report
+ non-deterministic push parser requests.
+ Update @output usage to @output(...@) form.
+ * data/glr.cc, data/lalr1.cc: Use b4_fatal instead of m4_fatal to

+ * src/main.c (main): Invoke skel_scanner_free.
+ * src/scan-skel.h (skel_scanner_free): Prototype new function.
+ * src/scan-skel.l (FLEX_NO_OBSTACK): Don't define; we now need the

+ (YY_DECL): Use to declare skel_lex static.
+ (decode_at_digraphs): Remove; now handled in the new
+ SC_AT_DIRECTIVE_ARG start condition.
+ (fail_for_at_directive_too_many_args, fail_for_invalid_at): New static
+ functions.
+ (at_directive_name, AT_DIRECTIVE_ARGC_MAX, at_directive_argc,
+ at_directive_argv): New static globals.
+ (INITIAL): Use fail_for_invalid_at.
+ Don't parse `@output file_name\n' or `@basename(...@)'. Instead,
+ recognize the start of a generalized `@directive(...@)' form and
+ start...
+ (SC_AT_DIRECTIVE_ARG): ... this new start condition to parse the
+ directive args (using the new obstack_for_string), to decode the
+ contained @ diagraphs, and to perform the directive. It recognizes
+ @basename(...@), @warn(...@), @complain(...@), @fatal(...@), and
+ @output(...@).
+ (SC_AT_DIRECTIVE_SKIP_WS): New start condition started by
+ SC_AT_DIRECTIVE_ARG to skip whitespace after the argument delimiter,
+ `@,'.
+ (scan_skel): Initialize obstack_for_string on the first call.
+ (skel_scanner_free): New function to free obstack_for_string.
+ * tests/input.at (Reject bad %code qualifiers): Update test output.
+
+2007-01-04 Joel E. Denny <jdenny@ces.clemson.edu>

+ * data/glr.cc: Update to use b4_user_code([b4_percent_code_requires])

+ which defines muscles of the form b4_percent_code_QUALIFIER and the

+ * src/scan-gram.l (PERCENT_CODE_TOP, PERCENT_PROVIDES,
+ PERCENT_REQUIRES): Remove.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update to use

+
+2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface for destructors and printers.
+ * src/symtab.h (symbol, semantic_type): Remove destructor_location and
+ printer_location members, and change the type of the destructor and
+ printer members to code_props.
+ (symbol_destructor_set, symbol_destructor_get, symbol_printer_set,

+ semantic_type_printer_set, default_tagged_destructor_set,
+ default_tagless_destructor_set, default_tagged_printer_set,
+ default_tagless_printer_set): Use code_props in arguments and return
+ types in place of char const * and location.
+ (symbol_destructor_location_get, symbol_printer_location_get): Remove
+ since the locations are now contained in the return of
+ symbol_destructor_get and symbol_printer_get.
+ * src/output.c (symbol_destructors_output, symbol_printers_output):
+ Replace with...
+ (symbol_code_props_output): ... this to eliminate duplicate code.

+ (symbol_print): Use SYMBOL_CODE_PRINT.
+
+2007-01-03 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface for rule actions.
+ * src/symlist.h (symbol_list): Replace action, action_location, and

+ * src/reader.c (symbol_should_be_used, grammar_rule_check,

+
+2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Use the new code_props interface in parse-gram.y.
+ * src/parse-gram.y (prologue_declaration, braceless, epilogue.opt):
+ Update all uses of translate_* functions to use the new code_props
+ interface and to use gram_scanner_last_string_free and
+ code_scanner_last_string_free where possible.
+ (grammar_declaration): symbol_list_destructor_set and
+ symbol_list_printer_set now perform the translation, so don't do it
+ here. Use gram_scanner_last_string_free where possible.
+ * src/scan-code.h, src/scan-code.l (translate_symbol_action,
+ translate_code): Remove, no longer used.
+ * src/symlist.h, src/symlist.c (symbol_list_destructor_set,
+ symbol_list_printer_set): Perform code translation here rather than
+ depending on the caller to do so.
+
+ * src/symlist.h (struct symbol_list): Correct some documentation typos.
+ * src/scan-gram.h (gram_last_string): Remove declaration.
+ * src/scan-gram.l (last_string): Declare it static.
+
+2007-01-02 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Encapsulate code properties and related functionality for the various
+ destructors, printers, and actions into a code_props structure and
+ interface. This patch merely implements code_props in scan-code.h and
+ scan-code.l. Future patches will rewrite other modules to use it.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-11/msg00020.html>.
+ * src/location.h (EMPTY_LOCATION_INIT): Define so that it's easier to
+ consistently initialize const structs that have an empty location
+ field.
+ * src/location.c (empty_location): Initialize with EMPTY_LOCATION_INIT
+ to ensure consistency.
+ * src/scan-code.h (code_props): New structure.
+ (code_props_none_init, CODE_PROPS_NONE_INIT, code_props_none): New
+ function, macro, and const global variable for initializing a
+ code_props with no code.
+ (code_props_plain_init, code_props_symbol_action_init,
+ code_props_rule_action_init, code_props_translate_code): The rest of
+ the new code_props functional interface. Among other things, the init
+ functions set the code_props kind field so that
+ code_props_translate_code will know whether to behave like
+ translate_symbol_action, translate_rule_action, or translate_code.
+ These old translate functions must remain until all other modules are
+ updated to use the new code_props interface.
+ (code_scanner_last_string_free): New function similar to
+ gram_scanner_last_string_free.
+ (code_scanner_free): Add documentation.
+ * src/scan-code.l: Implement the new interface.
+ (code_lex): Make it static, add a code_props* argument, and remove the
+ rule argument.
+ (last_string): New static global similar to the one in scan-gram.l.
+ (SC_RULE_ACTION): Update to use the code_props* argument to code_lex
+ instead of rule.
+ (SC_SYMBOL_ACTION): For $$, set the is_value_used member of the
+ code_props since Bison may one day use this information for destructors
+ and printers.
+ (<*><<EOF>>): Use STRING_FINISH so that last_string is set.
+ (handle_action_dollar): Use symbol_list_n_get and set used flag
+ directly since symbol_list_n_used_set is removed.
+ (translate_action): Add a code_props* argument and remove the rule,
+ action, and location arguments. Pass the code_props* on to code_lex.
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Rewrite as wrappers around the new code_props interface.
+ * src/symlist.h, src/symlist.c (symbol_list_n_used_set): Remove since
+ it would eventually need to break the encapsulation of code_props.
+
+2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * etc/.cvsignore: New.
+
+2007-01-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Add maintainer-push-check to run maintainer-check using push parsing in
+ place of pull parsing where available.
+ * Makefile.am (maintainer-push-check): New.
+ * data/bison.m4 (b4_use_push_for_pull_if): New.
+ * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
+ appropriately based on their existing values.
+ (yypush_parse): Don't print push-parser-specific diagnostics if push
+ parsing is being used in place of pull parsing.
+ * data/yacc.c: If push parsing should replace pull parsing, redirect to
+ push.c.
+ * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
+ variable, and insert b4_use_push_for_pull_flag into muscles.
+ * tests/Makefile.am (maintainer-push-check): New.
+
+2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
+ (whether successful or failed) so that yypush_parse can be invoked
+ again to start a new parse using the same yypstate.
+ * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
+ check multiple yypull_parse invocations on the same yypstate. For pull
+ mode, extend to check multiple yyparse invocations.
+ (Exploding the Stack Size with Alloca): Extend to try with
+ %push-pull-parser.
+ (Exploding the Stack Size with Malloc): Likewise.
+
+ * tests/calc.at (Simple LALR Calculator): Don't specify
+ %skeleton "push.c" since %push-pull-parser implies that now.
+ * tests/headers.at (export YYLTYPE): Don't check for the push
+ declarations. Otherwise, this test case can't be used to see if push
+ mode can truly emulate pull mode.
+ * tests/input.at (Torturing the Scanner): Likewise.
+ * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
+ (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
+ AT_YACC_IF, which now includes the case of push mode since %skeleton
+ need not be used for push mode. This will be more intuitive once
+ push.c is renamed to yacc.c.
+
+2006-12-31 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For push mode, convert yyparse from a macro to a function, invoke yylex
+ instead of passing a yylexp argument to yypull_parse, and don't
+ generate yypull_parse or yyparse unless %push-pull-parser is declared.
+ Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00163.html>.
+ * data/bison.m4 (b4_pull_if): New.
+ * data/c.m4 (b4_identification): Define YYPULL similar to YYPUSH.
+ * data/push.c: Improve M4 quoting a little.
+ (b4_generate_macro_args, b4_parenthesize): Remove.
+ (yyparse): If there's a b4_prefix, #define this to b4_prefix[parse]
+ any time a pull parser is requested.
+ Don't #define this as a wrapper around yypull_parse. Instead, when
+ both push and pull are requested, make it a function that does that
+ same thing.
+ (yypull_parse): If there's a b4_prefix, #define this to
+ b4_prefix[pull_parse] when both push and pull are requested.
+ Don't define this as a function unless both push and pull are
+ requested.
+ Remove the yylexp argument and hard-code yylex invocation instead.
+ * etc/bench.pl.in (bench_grammar): Use %push-pull-parser instead of
+ %push-parser.
+ * src/getargs.c (pull_parser): New global initialized to true.
+ * getargs.h (pull_parser): extern it.
+ * src/output.c (prepare): Insert pull_flag muscle.
+ * src/parse-gram.y (PERCENT_PUSH_PULL_PARSER): New token.
+ (prologue_declaration): Set both push_parser and pull_parser = true for
+ %push-pull-parser. Set push_parser = true and pull_parser = false for
+ %push-parser.
+ * src/scan-gram.l: Don't accept %push_parser as an alternative to
+ %push-parser since there's no backward-compatibility concern here.
+ Scan %push-pull-parser.
+ * tests/calc.at (Simple LALR(1) Calculator): Use %push-pull-parser
+ instead of %push-parser.
+ * tests/headers.at (export YYLTYPE): Make yylex static, and don't
+ prototype it in the module that calls yyparse.
+ * tests/input.at (Torturing the Scanner): Likewise.
+ * tests/local.at (AT_PUSH_IF): Check for %push-pull-parser as well.
+
+2006-12-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Update etc/bench.pl. Optimize push mode a little (the yyn change
+ deserves most of the credit).
+ * Makefile.am (SUBDIRS): Add etc subdirectory.
+ * configure.ac (AC_CONFIG_FILES): Add etc/bench.pl and etc/Makefile.
+ * data/push.c (b4_declare_parser_state_variables): Move yyn, yyresult,
+ yytoken, yyval, and yyloc declarations to...
+ (yyparse or yypush_parse): ... here to improve performance. For
+ yypush_parse invocations after the first, be sure to assign yyn its old
+ value again.
+ (yypstate_new): Don't bother initializing the yyresult field since the
+ initial value isn't used.
+ (yyn, yyresult, yytoken, yyval, yyloc): For each NAME in this list,
+ remove the #define that, in push mode, set it to yyps->NAME.
+ * etc/Makefile.am: New.
+ * etc/bench.pl: Remove and build it instead from...
+ * etc/bench.pl.in: ... this new file. Use @abs_top_builddir@ to invoke
+ "tests/bison" from the build directory by default rather than just
+ invoking "bison" from $PATH.
+ (calc_grammar): Update push parser code: don't declare yylval globally,
+ don't define yyparse_wrapper, and don't #define yyparse.
+ (bench_grammar): Update to check all working combinations of yacc.c,
+ push.c, impure, pure, pull, and push.
+
+2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ For push mode, add pull wrappers around yypush_parse.
+ * data/push.c: (b4_generate_macro_args, b4_parenthesize): New macros.
+ (yypull_parse): New function wrapping yypush_parse.
+ (yyparse): New #define wrapping yypull_parse.
+ * tests/calc.at (_AT_DATA_CALC_Y): Call yyparse even when %push-parser
+ is declared.
+ * tests/headers.at (export YYLTYPE): Make yylex global. For push mode,
+ prototype yylex in the module that calls yyparse, and don't prototype
+ yyparse there. Otherwise, the yyparse expansion won't compile.
+ * tests/input.at (Torturing the Scanner): Likewise.
+
+2006-12-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Enable push parsers to operate in impure mode. Thus, %push-parser no
+ longer implies %pure-parser. The point of this change is to move
+ towards being able to test the push parser code by running the entire
+ test suite as if %push-parser had been declared.
+ * data/push.c (yypush_parse): For impure mode, remove the
+ yypushed_char, yypushed_val, and yypushed_loc arguments.
+ Instead, declare these as local variables initialized to the global
+ yychar, yylval, and yylloc.
+ For the first yypush_parse invocation only, restore the initial values
+ of these global variables when it's time to read a token since they
+ have been overwritten.
+ * src/parse-gram.y (prologue_declaration): Don't set pure_parser for
+ %push-parser.
+ * tests/calc.at (Simple LALR(1) Calculator): Always declare
+ %pure-parser along with %push-parser since this test case was designed
+ for pure push parsers.
+ * tests/local.at (AT_PURE_OR_PUSH_IF): Remove unused.
+ (AT_YACC_OR_PUSH_IF): New.
+ (AT_YYERROR_SEES_LOC_IF): Fix enough that the test suite passes, but
+ add a note that it's still wrong for some cases (as it has been for a
+ while).
+ (AT_PURE_LEX_IF): Use AT_PURE_IF instead of AT_PURE_OR_PUSH_IF since
+ %push-parser no longer implies %pure-parser.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Remove some unnecessary differences between the pull parser code and
+ the push parser code. This patch enables yynerrs in push mode.
+ * data/push.c: Reformat M4 a little.
+ (b4_yyerror_range): Remove and convert all uses to just yyerror_range.
+ (b4_declare_scanner_communication_variables): Don't omit yynerrs just
+ because push mode is on. Instead, if pure mode is on, move yynerrs
+ to...
+ (b4_declare_parser_state_variables): ... here.
+ (yynerrs, yyerror_range): For push mode, #define each NAME in this list
+ to yyps->NAME so it can be used in yypush_parse.
+ (yypush_parse): Don't omit uses of yynerrs in push mode.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug such that the first pushed token's value and location are
+ sometimes overwritten (sometimes by %initial-action) before being used.
+ * data/push.c (yypush_parse): Rename arguments yynchar, yynlval, and
+ yynlloc to yypushed_char, yypushed_val, and yypushed_loc for clarity.
+ For the first yypush_parse invocation, initialize yychar to YYEMPTY to
+ more closely mimic the pull parser logic.
+ Don't copy the pushed token to yychar, yylval, and yylloc until it's
+ time to read a token, which is after any initialization of yylval and
+ yylloc.
+ (gottoken): Rename label to...
+ (yyread_pushed_token): ... for clarity and to avoid infringing on the
+ user namespace.
+
+2006-12-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Rearrange initialization of the parser state variables so that the
+ skeleton doesn't have to have a copy for pull mode and another for push
+ mode. This patch also fixes at least a bug such that yylloc was not
+ initialized (with b4_location_initial_line and
+ b4_location_initial_column) upon calling yypush_parse. However, that
+ initialization now overwrites the first token's location;
+ %initial-action assigning @$ already did the same thing, and both bugs
+ will be fixed in a later patch.
+ * data/push.c (b4_yyssa): Remove and convert all uses to just yyssa.
+ (b4_declare_parser_state_variables): Remove initialization of yytoken,
+ yyss, yyvs, yyls, and yystacksize.
+ (yypstate_new): Remove initialization of some yypstate fields: yystate,
+ yyerrstatus, yytoken, yyss, yyvs, yyls, yystacksize, yyssp, yyvsp, and
+ yylsp.
+ (yyssa, yyvsa, yylsa): For push mode, #define each NAME in this list to
+ yyps->NAME so it can be used in yypush_parse.
+ (yyparse or yypush_parse): For yypush_parse, don't print the
+ "Starting parse" diagnostic for invocations after the first.
+ Add initialization of yytoken, yyss, yyvs, yyls, and yystacksize; for
+ yypush_parse, only do it for the first invocation.
+ Allow yystate, yyerrstatus, yyssp, yyvsp, yylsp, and yylloc
+ initialization to occur in yypush_parse but only on the first
+ invocation.
+
+2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c: Add CPP guards around push parser declarations in both
+ the header and the code file.
+ In the code file, move the push parser declarations to the same place
+ they appear in the header file.
+ Clean up the M4 some, especially the inconsistent underquoting in
+ some b4_c_function_def and b4_c_function_decl uses.
+
+2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Encapsulate the push parser state variables into an M4 macro so the
+ push skeleton doesn't have to list them again for pull mode's yyparse.
+ For push mode, remove yypush_parse's local equivalents of these
+ variables to eliminate unnecessary copying between the two sets at
+ run-time. This patch also fixes at least a bug related to multiple
+ %initial-action invocations in push mode.
+ * data/push.c (b4_declare_parser_variables): Rename to...
+ (b4_declare_scanner_communication_variables): ... this for clarity and
+ update both uses.
+ (b4_declare_yyparse_variables): Remove and move its contents to the one
+ spot where it was invoked.
+ (b4_declare_parser_state_variables): New macro containing the parser
+ state variables required by push mode.
+ (struct yypstate): Replace all fields but yynew with
+ b4_declare_parser_state_variables.
+ (yystate, yyn, yyresult, yyerrstatus, yytoken, yyss, yyssp, yyvs,
+ yyvsp, yyls, yylsp, yystacksize, yyval, yyloc): For push mode, #define
+ each NAME in this list to yyps->NAME so it can be used in yypush_parse.
+ (yyparse or yypush_parse): For yyparse in pull mode, replace local
+ parser state variable declarations with
+ b4_declare_parser_state_variables.
+ Don't initialize parser state variables when calling yypush_parse since
+ yypstate_new already does that.
+ Invoke the user's initial action only upon the first yypush_parse
+ invocation.
+ Remove all code that copies between the local parser state variables
+ and the yypstate.
+
+2006-12-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/push.c (union yyalloc): Rename yyss, yyvs, and yyls fields to
+ prevent a name collision in a future patch where these names will
+ sometimes be #define'd.
+ (YYSTACK_RELOCATE): Add an argument to select a union yyalloc field
+ since it no longer has the same name as the existing argument.
+ (yyparse or yypush_parse): Update all uses of YYSTACK_RELOCATE.
+
+2006-12-19 Paolo Bonzini <bonzini@gnu.org>
+ and Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo (Decl Summary): In the %language entry, mention
+ that the argument is case-insensitive, and there's no `=' here.
+ For the %skeleton entry, mention that %language is better.
+ (Bison Options): Likewise for --language and --skeleton. Move the
+ --skeleton entry so that the `Tuning the parser' section is sorted
+ alphabetically on long options.
+ (C++ Bison Interface): Don't use the word skeleton. Don't explain the
+ %language directive in detail here; cross-reference the %language
+ documentation instead.
+ (Calc++ Parser): Use `%require "@value{VERSION}"' rather than
+ `%require "2.3b"' so that the example is always up-to-date.
+ (Table of Symbols): Add entries for %language and %skeleton.
+ * examples/extexi (normalize): Instead of replacing every %require
+ argument with the current Bison version, just substitute for
+ `@value{VERSION}'. This guarantees that we're testing what actually
+ appears in the documentation.
+ * examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
+ rather than `@VERSION@'.

+
+ * TODO: Add pointer to Sylvain Schmitz's work on static detection
+ of potential ambiguities in GLR grammers.
+
+2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
+ `bison ', use m4_index instead of m4_substr since chopping up a string
+ containing M4-special characters causes problems here.
+
+ Fix a couple of bugs related to special characters in user-specified
+ file names, and make it easier for skeletons to compute output file
+ names with the same file name prefix as Bison-computed output file
+ names.
+ * data/glr.cc, data/push.c, data/yacc.c: In @output, use
+ b4_parser_file_name and b4_spec_defines_file instead of
+ @output_parser_name@ and @output_header_name@, which are now redundant.
+ * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
+ b4_parser_file_name, b4_spec_defines_file, and the new
+ @basename(FILENAME@) instead of @output_parser_name@ and
+ @output_header_name@, which inappropriately escaped the file names as
+ C string literals.
+ * src/files.c (all_but_ext): Remove static qualifier.
+ (compute_output_file_names): Move `free (all_but_ext)' to...
+ (output_file_names_free): ... here since all_but_ext is needed later.
+ * src/files.h (all_but_ext): Extern.
+ * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
+ exactly what MUSCLE_INSERT_STRING used to do.
+ (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
+ characters are escaped properly.
+ * src/output.c (prepare): Define muscle file_name_all_but_ext as
+ all_but_ext.
+ For pkgdatadir muscle, maintain previous functionality by using
+ MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
+ is that b4_pkgdatadir is used inside m4_include in the skeletons, so
+ digraphs would never be expanded. Hopefully no one has M4-special
+ characters in his Bison installation path.
+ * src/scan-skel.l: Don't parse @output_header_name@ and
+ @output_parser_name@ anymore since they're now redundant.
+ In @output, use decode_at_digraphs.
+ Parse a new @basename command that invokes last_component.
+ (decode_at_digraphs): New.

+
+2006-09-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/getargs.c (usage): Rework to use conventions similar to

+
+2006-09-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ Use some of gnulib's new modules, taken from coreutils.

+ gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
+ * src/Makefile.am (DEFS): Remove, since configmake does this for us.
+ (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
+ * src/system.h: Include inttypes.h unconditionally, now that we
+ use the inttypes module. Don't bother to include stdint.h, since
+ inttypes.h now does that for us.
+ (LOCALEDIR): Remove, now that we use the configmake module.
+ * src/getargs.c: Include configmake.h.
+ * src/main.c: Likewise.
+ * src/output.c: Likewise.
+ * tests/atlocal.in (CPPFLAGS): Include from $abs_top_builddir/lib,

+
+
+ Port to GCC 2.95. First two problems reported by Michael Deutschmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+ * src/parse-gram.y (symbol_declaration): Don't put statements
+ before declarations; it's not portable to C89.
+ * src/scan-code.l (handle_action_at): Likewise.
+
+ * src/scan-code.l: Always initialize braces_level; the old code
+ left it uninitialized and therefore had undefined behavior.
+
+ Don't attempt to redefine 'assert', since it runs afoul of
+ systems where standard headers (mistakenly) include <assert.h>.
+ Instead, define and use our own alternative, called 'aver'.
+ * src/reader.c: Don't include assert.h, since we no longer
+ use assert.
+ * src/scan-code.l: Likewise.
+ * src/system.h (assert): Remove, replacing with....
+ (aver): New function, taking a bool arg. All uses changed.

+2006-09-15 Bob Rossi <bob@brasko.net>

+
+ Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero

+
+2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
+ We don't need them in glr.cc, and glr.c defines them.
+ Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
+ assumes that defining it to anything is the same as defining

+
+2006-09-12 Paolo Bonzini <bonzini@gnu.org> (tiny change)
+

+
+2006-09-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (b4_shared_declarations): Put start-header first,

+
+ * doc/bison.texinfo (Calc++ Parser): Fix memory leak reported by
+ Sander Brandenburg in

+ Also, fix minor white space and comment issues.
+ (Prologue): Mention that it's better to define feature-test macros

+
+ * README-cvs: Fix typo: "&" should be "&&". Problem reported

+
+ Require default %destructor/%printer to be declared using

+ * tests/actions.at, tests/input.at: Add %symbol-default to all default
+ %destructor/%printer declarations.
+
+2006-08-23 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Whether the default %destructor/%printer applies to a particular symbol
+ isn't a question of whether the user *declares* that symbol (in %token,
+ for example). It's a question of whether the user by any means
+ *defines* the symbol at all (by simply using a char token, for
+ example). $end is defined by Bison whereas any other token with token
+ number 0 is defined by the user. The error token is always defined by
+ Bison regardless of whether the user declares it with %token, but we
+ may one day let the user define error as a nonterminal instead.
+ * NEWS (2.3+): Say "user-defined" instead of "user-declared".
+ * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
+ the meaning of "user-defined".
+ * tests/actions.at (Default %printer and %destructor for user-declared
+ end token): Rename to...
+ (Default %printer and %destructor for user-defined end token): ...
+ this.
+
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
+ computation of whether to apply the default, don't maintain a list of
+ every Bison-defined symbol. Instead, just check for a first character
+ of '$', which a user symbol cannot have, and check for the error token.
+
+2006-08-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't apply the default %destructor or %printer to the error token,
+ $undefined, or $accept. This change fits the general rule that the
+ default %destructor and %printer are only for user-declared symbols,
+ and it solves several difficulties that are described in the new test
+ cases listed below.
+ * src/symtab.c (symbol_destructor_get, symbol_printer_get): Implement.
+ * tests/actions.at (Default %printer and %destructor are not for error
+ or $undefined, Default %printer and %destructor are not for $accept):
+ New test cases.
+
+2006-08-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Allow %start after the first rule.
+ * src/reader.c (grammar_current_rule_begin): Don't set the start symbol
+ when parsing the first rule.
+ (check_and_convert_grammar): Search for it here after all grammar
+ declarations have been parsed. Skip midrules, which have dummy LHS
+ nonterminals.
+ * src/symtab.c (symbol_is_dummy): New function.
+ * src/symtab.h (symbol_is_dummy): Declare it.
+ * tests/input.at (%start after first rule): New test.
+
+2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Redo some of the previous commit: add back the ability to use

+ commit: don't worry about complaints from symbols_pack.
+ * src/symtab.c (symbol_new, symbol_class_set,
+ symbol_check_alias_consistency): Undo changes in previous commit: count
+ each string literal as a new symbol and token, assign it a symbol
+ number, and don't complain about non-aliased string literals.
+ (symbols_pack): Since symbol_make_alias still does not decrement symbol
+ and token counts but does still set aliased tokens to the same number,
+ symbol_pack_processor now leaves empty slots in the symbols array.
+ Remove those slots.
+ * tests/regression.at (Undeclared string literal): Remove test case
+ added in previous commit since non-aliased string literals are allowed
+ again.
+ (Characters Escapes, Web2c Actions): Undo changes in previous commit:
+ remove unnecessary string literal declarations.
+ * tests/sets.at (Firsts): Likewise.
+
+2006-08-18 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't allow an undeclared string literal, but allow a string literal to
+ be used before its declaration.
+ * src/reader.c (check_and_convert_grammar): Don't invoke packgram if
+ symbols_pack complained.
+ * src/symtab.c (symbol_new): Don't count a string literal as a new

+ (symbol_class_set): Don't count a string literal as a new token, and
+ don't assign it a symbol number since symbol_make_alias does that.
+ (symbol_make_alias): It's not necessary to decrement the symbol and
+ token counts anymore. Don't assume that an alias declaration occurs
+ before any uses of the identifier or string, and thus don't assert that
+ one of them has the highest symbol number so far.
+ (symbol_check_alias_consistency): Complain if there's a string literal
+ that wasn't declared as an alias.
+ (symbols_pack): Bail if symbol_check_alias_consistency failed since
+ symbol_pack asserts that every token has been assigned a symbol number
+ although undeclared string literals have not.
+ * tests/regression.at (String alias declared after use, Undeclared
+ string literal): New test cases.
+ (Characters Escapes, Web2c Actions): Declare string literals as
+ aliases.
+ * tests/sets.at (Firsts): Likewise.
+
+2006-08-14 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In the grammar scanner, STRING_FINISH unclosed constructs and return
+ them to the parser in order to improve error messages.
+ * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
+ SC_BRACED_CODE, SC_PROLOGUE): Implement.
+ * tests/input.at (Unclosed constructs): New test case.
+ * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
+ seen.
+
+ * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
+ unused global.
+
+2006-08-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Handle string aliases for character tokens correctly.
+ * src/symtab.c (symbol_user_token_number_set): If the token has an
+ alias, check and set its alias's user token number instead of its own,
+ which is set to indicate the alias. Previously, every occurrence of
+ the character token in the grammar overwrote that alias indicator with
+ the character code.
+ * tests/input.at (String aliases for character tokens): New test.
+
+2006-08-12 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
+
+2006-08-11 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
+ to prevent failures when building on older platforms.
+ Check for autopoint failure.
+ Set XGETTEXT_OPTIONS to values that check for C format strings,
+ so that translators are warned about them (this also helps
+ prevent core dumps).
+
+ * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
+ function, since it simplifies our code a bit.
+
+ * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
+ rather than -W, so we don't get bogus warnings about sign comparisons.
+ Add -Wpointer-arith, since that warning is useful (it reports code
+ that does not conform to C89 and that some compilers reject).
+ * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
+ since it's no longer needed.
+
+2006-08-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up scanners a bit.
+ * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
+ definitions so gcc won't warn when obstack_for_string is unused.
+ * src/scan-code.l: config.h and system.h are already #include'd by
+ scan-code-c.c, so get rid of them here.
+ * src/scan-gram.l: Likewise.
+ * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
+ definitions rather than duplicating the rest of it.
+ * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
+
+2006-08-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Suppress signed/unsigned comparison warnings for yycheck.
+ * data/c.m4 (b4_safest_int_type): New macro.
+ * data/glr.c, data/lalr1.cc: Wherever you compare yycheck[i] against
+ a signed int type, cast it to b4_safest_int_type first.
+ * data/yacc.c: Likewise.
+ (b4_safest_int_type): Overwrite the one from c.m4 since b4_int_type is
+ also overwritten.
+
+2006-08-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de> (tiny change)
+
+ * doc/bison.texinfo: Fix some typos.
+
+2006-08-02 Paul Eggert <eggert@cs.ucla.edu>
+
+ * m4/.cvsignore: Add inttypes_h.m4,lib-ld.m4, lib-prefix.m4,
+ po.m4, stdint_h.m4, uintmax_t.m4, ulonglong.m4, warning.m4.
+
+ * bootstrap (gnulib_tool): Stop using --assume-autoconf;
+ the latest gnulib does this a different way.
+ (get_translations): Sharuzzaman Ahmat Raslan reported that the ms
+ translation was patched, so stop omitting it.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Enable declaration of default %printer/%destructor. Make the parser
+ use these for all user-declared grammar symbols for which the user does
+ not declare a specific %printer/%destructor. Thus, the parser uses it
+ for token 0 if the user declares it but not if Bison generates it as
+ $end. Discussed starting at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-02/msg00064.html>,
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>,
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00019.html>.
+ * NEWS (2.3+): Mention.
+ * doc/bison.texinfo (Actions in Mid-Rule): It's no longer impossible to
+ declare a %destructor for a mid-rule's semantic value. It's just
+ impossible to declare one specific to it.
+ (Freeing Discarded Symbols): Mention that @$ can be used in %destructor
+ code. Describe default %destructor form.
+ * src/parse-gram.y (grammar_declaration): Parse default
+ %printer/%destructor declarations.
+ * src/output.c (symbol_destructors_output): Use symbol_destructor_get
+ and symbol_destructor_location_get rather than accessing the destructor
+ and destructor_location members of struct symbol.
+ (symbol_printers_output): Likewise but for %printer's.
+ * src/reader.c (symbol_should_be_used): Likewise but for %destructor's
+ again.
+ * src/symtab.c (default_destructor, default_destructor_location,
+ default_printer, default_printer_location): New static global
+ variables to record the default %destructor and %printer.
+ (symbol_destructor_get, symbol_destructor_location_get,
+ symbol_printer_get, symbol_printer_location_get): New functions to
+ compute the appropriate %destructor and %printer for a symbol.
+ (default_destructor_set, default_printer_set): New functions to set the
+ default %destructor and %printer.
+ * src/symtab.h: Prototype all those new functions.
+ * tests/actions.at (Default %printer and %destructor): New test to
+ check that the right %printer and %destructor are called, that they're
+ not called for $end, and that $$ and @$ work correctly.
+ (Default %printer and %destructor for user-declared end token): New
+ test to check that the default %printer and %destructor are called for
+ a user-declared end token.
+ * tests/input.at (Default %printer and %destructor redeclared, Unused
+ values with default %destructor): New tests to check related grammar
+ warnings and errors.
+
+2006-07-29 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up handling of %destructor for the end token (token 0).
+ Discussed starting at

+ and
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00013.html>.
+
+ Make the skeletons consistent in how they pop the end token and invoke
+ its %destructor.
+ * data/glr.c (yyrecoverSyntaxError, yyparse): Don't pop the start
+ state, which has token number 0, since this would invoke the
+ %destructor for the end token.
+ * data/lalr1.cc (yy::parser::parse): Don't check for the final state
+ until after shifting the end token, or else it won't be popped.
+ * data/yacc.c (yyparse): Likewise.
+
+ * data/glr.c (yyparse): Clear the lookahead after shifting it even when
+ it's the end token. Upon termination, destroy an unshifted lookahead
+ even when it's the end token.
+ * data/lalr1.cc (yy::parser::parse): Likewise.
+ * data/yacc.c (yyparse): Likewise.
+
+ * src/reader.c (packgram): Don't check rule 0. This suppresses unused
+ value warnings for the end token when the user gives the end token a
+ %destructor.
+
+ * tests/actions.at (Printers and Destructors): Test all the above.
+
+2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Update to latest gnulib and gettext versions.
+ * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
+ Add fopen-safer.
+ (gnulib_files): Add m4/warning.m4. Don't worry about files
+ overwritten by autopoint.
+ Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
+ Suppress "id", "ms", "tr" translations for now, since gettext 0.15
+ rejects them.
+ Don't use autoreconf; instead, invoke autopoint etc. by hand,
+ so that we can remove the intl files at a better time.
+ (intl_files_to_remove): Remove aclocal.m4, since it gets
+ rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
+ m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
+ m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
+ Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
+ Remove datarootdir hack; no longer needed.
+ * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
+ (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
+ * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
+ strdup.h.
+ * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
+ * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
+
+2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Adjust to today's change to gnulib-tool by invoking
+ it with --assume-autoconf='latest-stable'.
+
+2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
+ least 1.4.7 and 1.4.4) by putting a #line between `typedef union
+ YYSTYPE' and `{'.
+ * src/muscle_tab.h (muscle_grow): Replace the header comments with
+ those from muscle_tab.c since the old ones are misleading.
+
+2006-07-13 Akim Demaille <akim@epita.fr>
+
+ Support %define "KEY" {VALUE}.
+ * src/scan-code.h, src/scan-code.l (translate_action)
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Return char *, not const char *.
+ * src/parse-gram.y (declaration): Rename as...
+ (prologue_declaration): this.
+ (string_content): Remove this nonterminal, use STRING.
+ (braceless, content, content.opt): New nonterminal.
+ Use them.
+ (%define): Now accept content.opt, i.e., accept also BRACED_CODE
+ as value.
+ * src/scan-gram.l (getargs.h): Don't include it.
+
+2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
+ rather than a for-loop that declares a local bool variable. This
+ should work around a compatibility problem with a Cray x1e C++
+ compiler reported by Hung Nguyen in
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
+ The for-loop was introduced in the 2004-11-17 change but I don't
+ know why it was needed.
+
+2006-07-12 Akim Demaille <akim@epita.fr>
+
+ * data/c.m4: Comment changes.
+
+2006-07-10 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/complain.c (error_message, ERROR_MESSAGE): New.
+ To factor...
+ (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
+ * src/complain.h, src/complain.c (warning_issued): Remove, unused.
+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Instead of %union, you can define and use your own union type
+ YYSTYPE if your grammar contains at least one <type> tag.
+ Your YYSTYPE need not be a macro; it can be a typedef.
+ * doc/bison.texinfo (Value Type, Multiple Types, Location Type):

+ * data/yacc.c (YYSTYPE): Likewise.
+ * src/output.c (prepare): Output tag_seen_flag.
+ * src/parse-gram.y (declaration, grammar_declaration):
+ Use 'union_seen' rather than 'typed' to determine whether
+ %union has been seen, since grammars can now be typed without
+ %union.
+ (symbol_declaration, type.opt, symbol_def):
+ Keep track of whether a tag has been seen.
+ * src/reader.c (union_seen, tag_seen): New vars.
+ (typed): remove.
+ * src/reader.h (union_seen, tag_seen, typed): Likewise.
+ * src/scan-code.l (untyped_var_seen): New variable.
+ (handle_action_dollar): Adjust to above changes.
+ (handle_action_dollar, handle_action_at):
+ Improve overflow checking for outlandish numbers.
+ * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
+ avoid new diagnostics generated by above changes.
+ * tests/regression.at (YYSTYPE typedef): Add test to check
+ for type tags without %union.
+
+ * src/symlist.c (symbol_list_length): Return int, not unsigned
+ int, since callers expect int. This may need to get revisited
+ once we have proper integer overflow checking.
+
+ * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
+ object is now static.
+
+ * src/getargs.c (flags_argmatch): Return void, not int,
+ to pacify ./configure --enable-gcc-warnings.
+
+ * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
+ since last_string is already defined to FLEX_PREFIX (last_string).
+
+2006-07-09 Akim Demaille <akim@lrde.epita.fr>
+
+ Implement --warnings/-W.
+ * src/getargs.c (report_argmatch, trace_argmatch): Remove,

+ (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
+ Adjust callers.
+ * src/getargs.h, src/getargs.c (warnings, warnings_flags)
+ (warnings_args, warnings_types): New.
+ (getargs, short_options, long_options): Accept -W/--warnings.
+ Sort the options by alphabetical order, upper case letter right
+ before its lower case.
+
+2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Change %merge result type clash warnings to errors. Discussed at

+
+2006-07-09 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/getargs.h, src/getargs.c: Swap --report and --trace handling

+ (trace_args): Spelling fixes.
+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
+ so they don't collide with user-defined macros.
+ (yy_stack_print): Don't assume that yytype_int16 promotes to int;
+ this was never guaranteed, and now that we're using gnulib stdint,
+ which defines int_fast16_t to long int, the problem is exposed.
+
+2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_basename): Simplify a bit, since we don't
+ need the full POSIX semantics (and weren't implementing them
+ anyway).
+
+ Adjust to Autoconf 2.60 and today's gnulib.
+ * bootstrap (gnulib_modules): Add stdint.
+ Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
+ no longer copies it.
+ (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
+ since stdint needs the former and wcwidth (which is now required
+ by mbswidth) needs the latter.
+ Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
+ work around a compatibility glitch between gettext 0.14.6 and
+ Autoconf 2.60.
+ * configure.ac (AC_PREREQ): Require Autoconf 2.60.
+ Do not check for uintptr_t, since new stdint module does the right
+ thing.
+ * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
+ Add stdint.h, stdint_.h, wcwidth.h.
+ * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
+ Add absolute-header.m4, double-slash-root.m4, longlong.m4,
+ stdint.m4, wchar_t.m4, wcwidth.m4.
+ * src/files.c: Include <dirname.h> and <stdio-safer.h> in the

+ (file_name_split): Use last_component, not base_name, to adjust
+ to gnulib changes.
+ * src/parse-gram.h: Include <strverscmp.h> in the usual order
+ for ../lib/*.h files.
+ (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
+ Define unconditionally, since we now assume the stdint module.
+ * src/scan-skel.l: Include <dirname.h>.
+ (BASE_QPUTS): Use last_component, not base_name.
+ * src/system.h: Include <unlocked-io.h> in the usual order

+ since we now use the stdint module.
+ (uintptr_t): Declare if UINTPTR_MAX is not defined, not
+ HAVE_UINTPTR_T, since we now use the stdint module.
+ (base_name): Remove decl, since files now include <dirname.h>
+ to get the decl.
+
+2006-07-08 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/c.m4 (b4_location_initial_column, b4_location_initial_line):

+2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In the grammar file, the first column is 1 not 0 on the first line as

+
+2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In warnings, say "previous declaration" rather than "first

+ * src/symtab.c (redeclaration): Do that here.
+ * src/reader.c (record_merge_function_type): In the case of a result

+ one in the grammar file.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is

+
+ * doc/Doxyfile.in: New.

+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't miss %merge result type warnings just because the LHS types are
+ declared after the %merge. This continues the effort of the previous

+ * src/reader.c (get_merge_function): Don't set the merger type yet.
+ (record_merge_function_type): New function for setting the merger type
+ and checking for clashes.
+ (grammar_current_rule_merge_set): Set the location of the %merge for
+ the current rule.
+ (packgram): Invoke record_merge_function_type for each rule now that
+ all symbol type declarations have been parsed.
+ * src/reader.h (merger_list.type_declaration_location): New member
+ storing the location of the first %merge from which the type for this

+ * src/symlist.h (symbol_list.merger_declaration_location): New member
+ storing the location of a rule's %merge, if any.

+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Get action warnings (grammar_rule_check) right even when symbol

+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
+ Don't mistake the type of $$ in a midrule to be that of its parent
+ rule's $$.
+ * src/reader.c (grammar_current_rule_end): Don't invoke
+ grammar_rule_check yet since not all symbol declarations may have been
+ parsed yet.
+ (grammar_midrule_action): Likewise.
+ Don't record whether the midrule's $$ has been used yet since actions
+ haven't been translated yet.
+ Record the midrule's parent rule and its RHS index within the parent
+ rule.
+ (grammar_current_rule_action_append): Don't translate the action yet
+ since not all symbol declarations may have been parsed yet and, thus,
+ warnings about types for $$, $n, @$, and @n can't be reported yet.
+ (packgram): Translate the action and invoke grammar_rule_check now that
+ all symbol declarations have been parsed.
+ * src/scan-code.l (handle_action_dollar): Now that this is invoked
+ after parsing the entire grammar file, the symbol list here in the case
+ of a midrule is actually the midrule's empty RHS, so reference its
+ parent rule's RHS where necessary.
+ On the other hand, now that you can already know it's a midrule, you
+ aren't forced to think $$ has the same type as its parent rule's $$.
+ (handle_action_at): In the case of a midrule, reference the parent rule
+ where necessary.
+ * src/symlist.c (symbol_list_new): Initialize new midrule-related
+ members.
+ (symbol_list_length): Now that this is invoked after all rules have
+ been parsed, a NULL symbol (rather than a NULL symbol list node)
+ terminates a rule. symbol_list_print already does this correctly.
+ * src/symlist.h (symbol_list.midrule_parent_rule,
+ symbol_list.midrule_parent_rhs_index): New members so that midrules can
+ remember their relationships with their parents.
+ * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
+ fixed by the above patch.
+ (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
+ implementing...
+ (Unused values): ... this old test case and...
+ (Unused values before symbol declarations): ... this new test case.
+ This one is the same as `Unused values' except that all symbol
+ declarations appear after the rules in order to catch the rest of the
+ errors fixed by the above patch.
+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ More cleanup.
+ * src/reader.c (current_rule): Declare it static since it's no longer

+ (grammar_current_rule_action_append): Remove redundant arguments from

+ * src/reader.h (current_rule): Remove this unused extern.

+ * src/scan-code.l (translate_rule_action): Likewise.
+
+2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up yesterday's patch.
+ * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
+ to...
+ * src/reader.c (grammar_current_rule_action_append): ... here for

+ * tests/regression.at (Braced code in declaration in rules section):
+ Make yyerror and yylex static as usual.
+
+2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug that mistakes braced code in a declaration in the rules section
+ to be a rule action. Mentioned at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
+ * src/scan-gram.l: Move midrule action detection from the start of the
+ scanning of any braced code to...
+ * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
+ action. For readability, use $2 and @2 rather than the equivalent

+
+ The Translation Project changed its way of publishing translations
+ to maintainers. I haven't received any responses to my request

+ (SC_PRE_CODE, token_type): Remove.
+ * src/parse-gram.y (%union): New field `character'.
+ Sort tokens.
+ (CHAR): New token.
+ (ID, ID_COLON): Now that the scanner no longer makes them

+ (id_colon): New, wraps the conversion from string to symbol.
+ (%union): Accept a possible union_name.
+ (symbol): Now can be a char.

+ * src/.cvsignore: Add revision.c.
+ * src/Makefile.am (bison_SOURCES): Add revision.c and revision.h.
+ (BUILT_SOURCES): Add revision.c.

+ or, if VERSION doesn't contain `+', with the empty string.
+ * src/getargs.c (version): Print the value of revision.

+
+ * data/glr.c (YYRECOVERING): Define to be a function-like macro
+ with no arguments, not as an object-like macro. This is for
+ compatibility with data/yacc.c. Problem reported by John P. Hartmann in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00059.html>.

+
+2006-05-29 Paul Eggert <eggert@cs.ucla.edu>

+
+2006-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+ shell, not within 'make', so that 'make' by an ordinary builder
+ (using GNU make) does not worry about configuring gzip. This also
+ works around a bug reported independently by Keith Thompson and by
+ Georg Schwarz, whereby gzip 1.2.4 --help would output usage on

+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+ to make sure that YYID will never be unused. This fixes a 'make
+ maintainer-check' failure caused by the recent changes to the 'Trivial
+ grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+ not used.
+ * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.
+
+2006-05-21 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+ state before an empty RHS is always resolved here. Only the location
+ of that state is guaranteed to be resolved, and that's enough. This
+ fixes the remaining bug reported by Derek M. Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * tests/glr-regression.at (Uninitialized location when reporting
+ ambiguity): Test the above case.
+ Also, the embedded comments in this test case claim it checks the case
+ of an empty RHS that has inherited the initial location. However, the
+ corresponding LHS was already resolved, so yyresolveLocations didn't
+ actually have reason to modify it. Fix this by forcing
+ nondeterministic operation at the beginning of the parse.
+
+2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_yy_symbol_print_generate):
+ (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+ 'const YYSTYPE', and similarly for YYLTYPE. This fixes one
+ of the bugs reported today by Derek M Jones in
+ <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+ * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+ defined to be a type name without parens or brackets.
+ (Location Type): Similarly for YYLTYPE.
+ * tests/regression.at (Trivial grammars): Put in a test for this
+ bug that will be caught by 'make maintainer-check' (though not,

+ taken from the yys parameter. When reporting a discarded merged value
+ in debugging output, note that it is incompletely merged. Document the

+ (yyresolveAction): If resolving any of the RHS states fails, destroy
+ them all rather than leaking them. Thus, as long as user actions are

+ "make check" doesn't finish with "All 1 tests passed".
+
+ * tests/regression.at (Token definitions): Don't rely on
+ AT_PARSER_CHECK for data that contains backslashes. It currently
+ uses 'echo', and 'echo' isn't portable if its argument contains
+ backslashes. Problem found on OpenBSD 3.4. Also, do not assume
+ that the byte '\0xff' is not printable in the C locale; it is,
+ under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
+ not printable, so use '\0x81' to test.
+
+ * data/glr.c (YYOPTIONAL_LOC): Define even if it's not a recent
+ version of GCC, since the macro is used with non-GCC compilers.
+
+ Fix core dump reported by Pablo De Napoli in

+ * tests/regression.at (Invalid inputs with {}): New test.
+ * src/parse-gram.y (token_name): Translate type before using

+ ((__unused__)).
+ (yyFail, yyMemoryExhausted, yyreportAmbiguity):
+ Add __attribute__ ((__noreturn__)).

+ (alpha, beta, major): Depend on news-date-check.
+ Make the upload commands.

+
+2005-07-22 Paul Eggert <eggert@cs.ucla.edu>
+

+ * THANKS: Add Anthony Heading, twlevo@xs4all.nl.
+
+ * bootstrap: For translations that have not yet been upgraded to

+
+2005-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix more problems reported by twlevo@xs4all.nl.
+ * tests/cxx-type.at: Don't pipe output of ./types through sed to
+ remove trailing spaces. This loses the exit status of ./types,

+ spaces.
+ * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
+ as the stack isn't valid in that case.
+
+ * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
+ (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):

+
+ * NEWS: Document minor wording changes in diagnostics of

+ * data/c.m4 (b4_yysymprint_generate): Use YYFPRINTF, not fprintf.
+
+ Add i18n support to the GLR skeleton. Partially fix the C++
+ skeleton; a C++ expert needs to finish this. Remove debugging
+ msgids; there's little point to having them translated, since they
+ can be understood only by someone who can read the
+ (English-language) source code.
+
+ Generate runtime-po/bison-runtime.pot automatically, so that we
+ don't have to worry about garbage getting in that file. We'll
+ make sure after the next official release that old msgids don't
+ get lost. See
+ <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
+
+ * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
+ Now auto-generated.
+ * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
+ Fix typos in explanations of the runtime file.
+ * bootstrap: Change gettext keyword from YYI18N to YY_.
+ Use standard Makefile.in.in in runtime-po, since we'll arrange
+ for backward-compatible bison-runtime.po files in a different way.
+ * data/glr.c (YY_): New macro, from yacc.c.
+ (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
+ Translate messages intended for users.
+ (yyreportSyntaxError): Change "virtual memory" to "memory" to match
+ the wording in the other skeletons. We don't know that the memory
+ is virtual.
+ * data/lalr1.cc (YY_): Renamed from _. All uses changed.
+ Use same method that yacc.c uses.
+ Don't translate debugging messages.
+ (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
+ it doesn't work (yet), and requires C++ expertise to fix.
+ * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
+ Move defn to a more logical place, to be consistent with other
+ skeletons.
+ Don't translate debugging messages.
+ Don't assume line numbers fit in unsigned int; use unsigned long fmts.
+ * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
+ to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
+ * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.
+
+ Fix yyerror / yylex test glitches noted by twlevo@xs4all.nl.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Have yyerror return
+ void, not int.
+ * tests/glr-regression.at (Badly Collapsed GLR States):
+ Likewise.
+ (Improper handling of embedded actions and dollar(-N) in GLR parsers):
+ yylex should return 0 at EOF rather than aborting.
+
+ Improve tests for stack overflow in GLR parser.
+ Problem reported by twlevo@xs4all.nl.
+ * data/glr.c (struct yyGLRStack): Remove yyerrflag member.
+ All uses removed.
+ (yyStackOverflow): Just longjmp, but with value 2 so that caller
+ can handle the problem.
+ (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
+ (yyparse): New local variable yyresult to record the result.
+ Use result of setjmp to set it, rather than storing itinto
+ struct.
+ (yyDone): Remove label.
+ (yyacceptlab, yyabortlab, yyoverflowlab, yyreturn): New labels,
+ to mimic yacc.c. Do not discard lookahead if it's EOF (possible
+ if YYABORT is used).
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Exit with
+ yyparse status; put status > 1 into diagnostic.
+ Check that status==2 works.
+ * tests/calc.at, tests/cxx-type.at, tests/glr-regression.at:
+ Use exit status 3 for failure to open (which shouldn't happen).
+
+2005-07-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/conflicts.at (%nonassoc and eof): Don't exit with status
+ 1 on syntax error; just let yyparse do its thing.
+ * tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
+ * tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
+ (Exploding the Stack Size with Alloca):
+ (Exploding the Stack Size with Malloc):
+ Expect exit status 2, not 1, since the parser is supposed to blow
+ its stack. Problem reported by twlevo@xs4all.nl.
+
+ * data/glr.c (yyparse): Don't assume that the initial calls
+ to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
+ Print a stack-overflow message and fail instead.
+ Initialize the line-number information before creating the stack,
+ so that the stack-overflow message can report line zero safely.
+
+2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix problems reported by twlevo@xs4all.nl.
+ * data/glr.c (YYSTACKEXPANDABLE): Don't define if already defined.
+ (yyuserMerge): Provide a default case if b4_mergers is empty.
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Define YYSTACKEXPANDABLE.
+ * tests/glr-regression.at
+ (Improper handling of embedded actions and dollar(-N) in GLR parsers):
+ Add casts to pacify C++ compilers.
+ * tests/glr-regression.at (Improper merging of GLR delayed action
+ sets): Declare yylex before using it.
+ * tests/Makefile.am (maintainer-check-g++): Fix a stray
+ $(GXX) that escaped the renaming of GXX to CXX. Remove bogus
+ test for valgrind; valgrind is independent of g++.
+ (maintainer-check-posix): Add _POSIX2_VERSION=200112, to check
+ for compatibility with POSIX 1003.1-2001 (if running coreutils).
+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Port to stricter C++.
+ Use a destructor, so that we can expand the stack. Change
+ YYSTYPE to char * so that we can free it. Cast result of malloc.
+
+2005-07-13 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
+
+ * data/glr.c (yyuserAction): Fix uninitialized variable that caused
+ a valgrind failure. Problem reported by twlevo@xs4all.nl.

+ * src/getarg.c (PRINT_LOCALEDIR_OPTION): Let the C compiler determine
+ its value.
+ * src/main.c (main): Bind the bison-runtime domain, too.
+
+2005-07-12 Bruno Haible <bruno@clisp.org>
+
+ * data/yacc.c: Include <libintl.h> when NLS is enabled.

+ sets yylloc and yylval, respectively.
+
+ * data/yacc.c (yyparse): In the initial action, set
+ yylsp[0] and yyvsp[0] rather than yylloc and yylval.

+
+2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ * examples/calc++/calc++-driver.cc, examples/calc++/calc++-driver.hh:
+ * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
+ Remove from CVS. These files are automatically generated.
+ * examples/extexi: Clarify that this file is now part of Bison,
+ not GNU M4, and that it works with any POSIX-compatible Awk.
+ * examples/calc++/Makefile.am (run_extexi): Remove; not used.
+ ($(calc_extracted)): Renamed from $(calc_sources_extracted),
+ so that we also get calc++-parser.yy. Geneate it.
+ Use $(AWK), not gawk, since any conforming Awk will do.
+ Put comment before action, since older 'make' can't handle comment
+ in action.
+ $(BUILT_SOURCES): List all built sources, not just some of them.
+ $(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
+ $($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.

+
+2005-07-05 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (yyFail): Drastically simplify; since the format argument
+ never had any % directives, we can simply pass it to yyerror.
+ (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
+ be modified later, as that is the usual style in glr.c.
+ Problems reported by Paul Hilfinger.
+
+ Rewrite GLR parser to catch more buffer overrun, storage exhaustion,
+ and size overflow errors.
+ * data/glr.c: Include <stdio.h> etc. after user prolog, not before,
+ in case the user prolog sets feature-test macros like _GNU_SOURCE.
+ (YYSIZEMAX): New macro.
+ (yystpcpy): New function, taken from yacc.c.
+ (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
+ (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
+ so that we don't have to maintain their signatures.
+ (yyFail): Check for buffer overflow, by using vsnprintf rather
+ than vsprintf. Allocate a bigger buffer if possible.
+ Report an error if buffer allocation fails.
+ (yyStackOverflow): New function.
+ (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
+ the initialization was successful. It might fail if storage was
+ exhausted.
+ (yyexpandGLRStack): Add more checks for storage allocation failure.
+ Use yyStackOverflow to report failures.
+ (yymarkStackDeleted, yyglrShift, yyglrShiftDefer, yydoAction):
+ (yysplitStack, yyprocessOneStack, yyparse, yypstack):
+ Don't assume stack number fits in int.
+ (yysplitStack): Check for storage allocation failure.
+ (yysplitStack, yyprocessOneStack): Add pure_formals, so that we
+ can print diagnostics on storage allocation failure. All callers
+ changed.
+ (yyresolveValue): Use yybool for boolean.
+ (yyreportSyntaxError): Check for size-calculation overflow.
+ This code is taken from yacc.c.
+ (yyparse): Check for storage allocation errors when allocating
+ the initial stack.

+ * data/yacc.c (YYSIZE_T): Define first, so that later decls can use it.
+ Prefer GCC's __SIZE_TYPE__ if available, so that we don't infringe on
+ the user's name space.
+ (alloca): Include <stdlib.h> to get it, if it's not built in.
+ (YYMALLOC, YYFREE): Define only if needed.
+ (malloc, free): Declare, but only if needed, as this infringes on

+
+ Various maintainer cleanups.
+ * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,

+
+ * data/lalr1.cc (yydestruct_): Pacify unused variable warning

+
+ Remove uses of 'short int' and 'unsigned short int'. This raises

+
+ This change does not affect the generated parsers; that's a different

+
+ Ideally we should use size_t to represent all object counts, and

+ (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):

+
+2004-10-22 Akim Demaille <akim@epita.fr>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove some arbitrary limits on goto numbers and relations.
+ * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit

+
+2004-10-05 Akim Demaille <akim@epita.fr>
+
+ In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
+ whether the reducion was empty or not. This leaves room to
+ improve the use of YYLLOC_DEFAULT in such a case.
+ lalr1.cc is still experimental, so changing this is acceptable.
+ And finally, there are probably not many users who changed the
+ handling of locations in GLR, so changing is admissible too.
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
+ empty reduction, set @$ to an empty location ending the previously
+ stacked symbol.
+ Adjust uses to make sure the code is triggered on empty
+ reductions.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
+ expected output: empty reductions have empty locations.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Move towards a more standard C++ coding style
+ for templates: Class < T > -> Class<T>.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Reinstall the former ctor, for sake of

+ Move towards a more standard C++ coding style (i.e., type *var ->

+
+2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (add_param): Rewrite to avoid strchr,

+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ Let the initial-action act on the look-ahead, and use it for the

+ And let lalr1.cc honor %initial-action.
+
+ * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
+ example.
+ * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
+ (Parser::Parser): Remove the ctor that used to initialize it.
+ (Parser::parse): Like in the other skeletons, issue the "starting

+ Honor %initial-action.
+ Initialize the stacks with the lookahead.
+ * data/yacc.c: Let $$ and @$ in %initial-action designate the

+
+ * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
+ clearer criterion to define it.
+ (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
+ When reducing on an empty RHS, use the latest stacked location as
+ location.
+ yylloc is not always available.
+ * data/glr.c: Likewise.
+ Also, honor initial-actions.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+

+ * data/c.m4 (b4_yysymprint_generate): Use it.
+ * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
+ value of the result.
+ (error_start_): Replace with...
+ (error_range_): this location array.
+ This allows to replace code relying on the implementation of
+ locations by portable code.
+ * data/yacc.c (yylerrsp): Replace with...
+ (yyerror_range): this.
+ Every time a token is popped, update yyerror_range[0], to have an
+ accurate location for the error token.
+ * data/glr.c (YY_LOCATION_PRINT): New.
+ (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
+ deference a pointer.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer

+
+ * src/scan-skel.l: Instead of abort, report error messages to ease

+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
+ (iterator, const_iterator): these, to be more in the C++ spirit.
+ Also, return reverse iterators so that when displaying the stack
+ we display its bottom first.
+ (Parser::stack_print_, Parser::reduce_print_): Match the messages
+ from yacc.c.
+ We should probably use vector here though.
+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ Have more complete shift traces.
+
+ * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
+ to report Shifts instead of ad hoc YYDPRINTF invocations,
+ including for the error token.
+ * data/lalr1.cc (symprint_): Output the location.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
+ output the location within the %printer.
+ Activate GLR tests, at least to make sure they compile properly.
+ They still don't pass though.
+ * tests/calc.at: Adjust expect verbose output, since now "Entering
+ state..." is on a different line than the "Shifting" message.
+
+2004-09-08 Akim Demaille <akim@epita.fr>
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
+ Bison directive from the Bison file to the invocation of this
+ macro, so that these directives are passed to
+ AT_BISON_OPTION_PUSHDEFS to get correct help macros.
+ Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
+ Move the AT_SETUP/AT_CLEANUP outside, to report as test title
+ the extra Bison directives instead of the whole series.
+ Change the grammar so that there are recoverable errors, and
+ unrecoverable errors. Now we can have the parser give up before
+ consuming the whole input. As a result we now can observe that
+ the lookahead is freed when needed.
+ Change the parser source to parse argv[1] instead of a hard coded
+ string.
+ Simplify yylex, and give a value and location to EOF.
+ Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
+ passed directives already coded in the file.
+ Add some tests to check the location of "error".
+ For some tests, the C++ parser is correct, and not yacc.c.
+ For other tests, they provide different, but unsatisfying, values,
+ so keep the C++ value so that at least one parser is "correct"
+ according to the test suite.
+ (Actions after errors): Remove, this is subsumed by the
+ AT_CHECK_PRINTER_AND_DESTRUCTOR series.
+

+ In addition, no longer depend on b4_yysymprint_generate and

+
+2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>

+
+2004-05-28 Albert Chin-A-Young <china@thewrittenword.com>
+
+ * tests/calc.at, tests/actions.at: Workaround for SGI
+ C++ compiler. (trivial change)
+
+2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Spent a few hours checking out which prerequisite versions the
+ current sources actually require. I went all the way back to
+ Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+ a seemingly endless set of combinations of versions more recent
+ than that. The bottom line is that the current sources require
+ fairly recent versions of the build tools, and it'll be some work
+ to change this.
+ * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+ (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+ (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+ Add comments explaining why those particular versions are
+ currently needed.
+
+ * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+ in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
+ <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+ * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+ (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+ 0.11.5. Suggested by Bruno Haible.
+ * bootstrap: Remove gettext version checking.
+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim
+ Van Holder.
+
+2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention GNU m4 1.4 bugs and Akim's patched version.
+ * README-alpha: Don't tell people not to package this.
+
+ * bootstrap: Don't assume $(...) works; use `...` instead.
+ Problem reported by Paul Hilfinger. Also, diagnose non-GNU
+ gettext better.
+
+ * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
+ put into the -d output file, and mention what to do if YYSTYPE is
+ defined as a macro.
+
+2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo change made earlier today: it caused autopoint to not bring
+ in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
+ autopoint's.
+
+ * bootstrap: Check that gettext version matches what's in
+ configure.ac. Warn users to ignore robots.txt ERROR 404.
+ * bootstrap: Undo today's earlier change (logged below).
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
+
+ The gettext version checking is causing more trouble than it's
+ curing; remove it. Problem reported by Paul Hilfinger.
+
+ * bootstrap: Issue a warning that one can expect a message
+ 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
+
+2004-05-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ Ensure that the C++ compiler used for testing actually works on a
+ simple test program; if not, skip the C++-related tests. Problem
+ reported by Vin Shelton in:
+ http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00026.html
+
+ * m4/cxx.m4: New file.

+ Problem reported by Troy A. Johnson
+ <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195946>.
+
+ * configure.ac (AC_INIT): Update to 1.875e.
+
+2004-05-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 1.875d.

+
+ * configure.ac (--enable-gcc-warnings): Do not enable -Wshadow,
+ -Wmissing-prototypes, or -Wstrict-prototypes for C++. The current
+ lalr1.cc runs afoul of the first, and the last two are no longer
+ supported by GCC 3.4.0.
+ * README: Mention GNU m4 1.4 or later; mention m4 patches.
+ * HACKING: Use ./bootstrap, not "make update" to import foreign files.
+
+2004-05-06 Paul Eggert <eggert@cs.ucla.edu>
+

+ stdint_h.m4, uintmax_t.m4, ulonglong.m4.
+ * src/.cvsignore: Add *.output.
+
+ * src/parse-gram.y: Put copyright notice inside %{ %} so it
+ gets copied to the output file.
+
+2004-04-28 Paul Eggert <eggert@twinsun.com>
+
+ Get files from the gnulib and po repositories, instead of relying
+ on them being in our CVS. Upgrade to latest versions of gnulib
+ and Automake.
+
+ * Makefile.am (SUBDIRS): Remove m4; Automake now does m4.
+ * bootstrap: Bootstrap from gnulib and po repositories.
+ Much of this code was stolen from GNU diff and GNU tar's bootstrap.
+ * README-cvs: Document these changes. Remove version numbers from
+ mentions of build tools, since they change so often. Mention Flex.
+
+ * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
+ (gl_USE_SYSTEM_EXTENSIONS): Add.
+ (AC_GNU_SOURCE, AC_AIX, AC_MINIX):
+ Remove; no longer needed, as gl_USE_SYSTEM_EXTENSIONS
+ does this for us.
+ (AC_ISC_POSIX): Remove; we no longer support this
+ ancient OS, as it gets in the way of latest Autoconf & gnulib.
+ (AC_HEADER_STDC): Remove: we now assume C89 or better.

+ Do not check for C89 headers, except for locale.h which is used
+ by the Yacc library and must port to K&R hosts.
+ (AC_CHECK_FUNCS_ONCE): Use instead of AC_CHECK_FUNCS.

+ AM_GNU_GETTEXT): Remove; now done by:
+ (GNULIB_AUTOCONF_SNIPPET): Add. "bootstrap" builds this for us.
+ (AC_CONFIG_FILES): Remove m4/Makefile, as Automake now does this
+ for us.
+
+ * lib/Makefile.am: Include gnulib.mk, built for us by "bootstrap".
+ (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES):
+ Define to empty, as gnulib.mk will do the rest for us.
+ ($(libbison_a_OBJECTS), stdbool.h): Remove, as gnulib.mk does this
+ for us.
+ (libbison_a_SOURCES): Define to $(lib_SOURCES) now.
+ (lib_SOURCES): New symbol, containing only the non-gnulib libs.

+
+2004-04-27 Paul Eggert <eggert@twinsun.com>

+
+2004-02-02 Paul Eggert <eggert@twinsun.com>
+
+ * src/Makefile.am (AM_CPPFLAGS): New macro. It mentions

+
+ * tests/local.at: Require Autoconf 2.59's Autotest.

+ When reducing initial empty rules, Bison parser read an initial

+
+ Fix a GLR parser bug I reported in February; see
+ <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
+ The problem was that GLR parsers did not conform to the C standard,
+ because actions like { $1 = $2 + $3; } expanded to expressions
+ that invoked YYFILL in separate subexpressions, and YYFILL assigned
+ to a local variable. The C standard says that expressions
+ like (var = f ()) + (var = f ()) have undefined behavior.
+ Another problem was that GCC sometimes issues warnings that
+ yyfill and its parameters are unused.
+
+ * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
+ as possibly unused.
+ (yyfill): New function.
+ (YYFILL): Use it.
+ (yyuserAction): Change type of yynormal to bool, so that it matches
+ the new yyfill signature. Mark it as possibly unused.
+
+
+ Follow up on a bug I reported in February, where a Bison-generated
+ parser can loop. Provide a test case and a fix for yacc.c. I
+ don't have a fix for lalr1.cc or for glr.c, unfortunately.
+ The original bug report is in:
+ <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
+
+ * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
+ macro's size was becoming unwieldy.
+ (yyerrlab): Do not discard an empty lookahead symbol, as this
+ might destroy garbage.
+ (yyerrorlab): New label, with the old contents of YYERROR,
+ plus the following change: pop the stack of rhs corresponding
+ to the production that invoked YYERROR. That is how Yacc
+ behaves, and POSIX requires this behavior.
+ (yyerrlab1): Use YYPOPSTACK instead of its definiens.
+ * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
+ Define 'alarm' to do nothing if unistd.h is not available.
+ Add a new rule "exp: '-' error;" to test the above change to
+ data/yacc.c. Use 'alarm' to abort any test taking longer than
+ 10 seconds, as it's probably looping.
+ (AT_CHECK_CALC): Test recovery from error in new grammar rule.

+2003-05-05 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
+ C89. This avoids a diagnostic on compilers that define __STDC__
+ to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-05-03 Paul Eggert <eggert@twinsun.com>
+
+ * lib/bitset.h (BITSET_FOR_EACH, BITSET_FOR_EACH_REVERSE):
+ Do not overrun array bounds.
+ This should fix a bug reported today by Olatunji Oluwabukunmi in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-05/msg00004.html>.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h, src/gram.c (pure_parser, glr_parser): Move to...
+ * src/getargs.c, src/getargs.h: here, as bool, not int.
+ (nondeterministic_parser): New.
+ * src/parse-gram.y, src/scan-gram.l: Support
+ %nondeterministic-parser.
+ * src/output.c (prepare): Use nondeterministic_parser instead
+ of glr_parser where appropriate.
+ * src/tables.c (conflict_row, action_row, save_row)
+ (token_actions, token_actions, pack_vector): Ditto.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (C++ Parsers, Implementing Loops): New.
+
+2003-04-29 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at: Also test yacc.c and glr.c (but not lalr1.cc yet)
+ with %pure-parser and %locations to exercise the patch from Yakov
+ Markovitch below.
+
+2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * data/yacc.c: (b4_lex_param): Corrected for the case where
+ %lex-param is provided and %pure-parser isn't.
+
+2003-04-27 Paul Eggert <eggert@twinsun.com>
+
+ Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
+ * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
+ if it is not defined.
+ (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
+
+2003-04-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+ Declare to be of type suitable for the ninf value itself, not of
+ type suitable for the corresponding table, since the latter might
+ be unsigned but the ninf value might be negative. This fixes a
+ bug reported by Alexandre Duret-Lutz in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+ * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+ invokes it. We shouldn't invoke it twice because it will attempt
+ to put error.o in the archive twice. This fixes a glitch reported
+ by Martin Mokrejs in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21 Paul Eggert <eggert@twinsun.com>
+
+ * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
+ to gnulib.
+
+2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
+
+ * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+ Fix obvious typo that results in uncompilable GLR parsers
+ when both %pure-parser and %locations are used. (trivial change)
+
+2003-04-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+ (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+ Do not insert the expected token via unput, as this runs afoul
+ of a POSIX-compatibility bug in flex 2.5.31.
+ All uses changed to BEGIN the parent state,
+ since we no longer insert the expected token via unput.
+ * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+ that is no longer emitted after the above change.
+
+ * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+ the first one. This change is from Paul Hilfinger, and it fixes
+ regression reported by Werner Lemberg in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+ (resolve_sr_conflict): Don't invoke state_errs_set
+ unless one or more tokens have been explicitly made errors.
+ Otherwise, the above change causes Bison to abort.
+
+ * tests/existing.at (GNU pic Grammar): New test case, taken from
+ Lemberg's email.
+
+2003-03-31 Akim Demaille <akim@epita.fr>

+ * doc/Makefile.am (AM_MAKEINFOFLAGS): Don't split the info file.
+
+2003-03-31 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (prepare_symbols): Avoid trailing spaces in the
+ output.
+
+2003-03-31 Akim Demaille <akim@epita.fr>

+ * doc/bison.texinfo (Strings are Destroyed): s/losses/loses/.
+ From Paul Hilfinger.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * m4/error.m4: Do not put under dynamic conditions some code which
+ expansion is under static control.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (How Can I Reset @code{yyparse}): New.
+
+2003-03-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Strings are Destroyed): New.
+
+2003-03-13 Paul Eggert <eggert@twinsun.com>
+
+ * .cvsignore: Add configure.lineno.
+ * src/.cvsignore: Add yacc.
+ * tests/.cvsignore: Add testsuite.log.
+ * doc/fdl.texi: Sync with latest FSF version.
+
+2003-03-12 Paul Eggert <eggert@twinsun.com>
+
+ * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+ (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+ cursor, instead of leaving it undefined. This fixes a bug
+ reported by Tim Van Holder in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+ * tests/input.at (Torturing the Scanner): Test the scanner on
+ an empty input file, which was Tim Van Holder's test case.
+
+ * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+ <sys/resource.h> can be included, include sys/time.h and
+ sys/times.h first, if available. This works around the SunOS
+ 4.1.4 porting bug reported by Bruce Becker in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+ * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+ AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+ AC_HEADER_SYS_WAIT.
+
+ Merge changes from gnulib. This was prompted because the CVS
+ snapshot didn't build on Solaris 7 due to strnlen problems.
+
+ These changes need to be merged back into gnulib:
+ * lib/hash.c: Include <stdbool.h> unconditionally.
+ * m4/onceonly.m4 (m4_quote): New macro.
+ (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

+
+ * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
+ Add.
+ (gl_ERROR): New, replacing jm_PREREQ_ERROR.

+
+ * src/system.h: Include <stdbool.h> unconditionally.
+
+ * lib/bbitset.h: Include <limits.h> unconditionally. We have been
+ assuming at least C89 in the bitset code for some time now.
+
+2003-03-03 Akim Demaille <akim@epita.fr>
+

+
+2003-03-02 Akim Demaille <akim@epita.fr>
+

+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
+ generate verbose error messages.
+ Use the number of tokens as an upper bound in yytname, as it
+ cannot be a non terminal.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
+ message.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
+ Use them to exercise yycheck overrun.
+ Based on Andrew Suffield's grammar.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ Create tests/local.at for Bison generic testing macros.
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
+ * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
+ This new file.
+ * tests/calc.at (AT_CHECK_CALC): Adjust.
+ * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
+ (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...

+ Ignore the test if CXX is not functional.
+
+2003-03-01 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+ not loc->end, since loc->end might contain garbage and this leads
+ to undefined behavior on some platforms.
+ (id_loc, token_start): Use (IF_LINTed) initial values that do not
+ depend on *loc, so that the reader doesn't give the the false
+ impression that *loc is initialized.
+ (<INITIAL>"%%"): Do not bother setting code_start, since its value
+ does not survive the return.
+
+2003-03-01 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l (code_start): Always initialize it when entering
+ into yylex, as SC_EPILOGUE is activated *before* the corresponding
+ yylex invocation. An alternative would be making it static, but
+ then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28 Paul Eggert <eggert@twinsun.com>
+
+ * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
+ around a UnixWare 7.1.1 porting bug reported by John Hughes in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
+
+2003-02-26 Paul Eggert <eggert@twinsun.com>
+
+ * README: Mention compiler bug in Sun Forte Developer 6 update 2.
+ Remove Sequent/Pyramid discussion (nobody uses them any more).
+ Merge VMS and MS-DOS discussion; these ports may well be dead
+ but let's keep mentioning them for now. Put <> around email

+
+2003-02-24 Paul Eggert <eggert@twinsun.com>
+

+ Suggested by Paul Eggert.
+
+2003-02-21 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Use "location" consistently to refer to @n,
+ to avoid confusions with lalr1.cc's notion of Position.
+ Suggested by Paul Eggert.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): Make sure "columns" never pushes
+ before initial_columns.
+ (location.hh): Use consistent variable names when defining the
+ operator<<.
+ Use "last" so that we subtract from Positions, not from unsigned.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): New subfile, including the extended
+ and Doxygen'ed documentation of class Position.
+ (location.hh): Use it.
+ Document a` la Doxygen.
+ With the help of Benoit Perrot.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
+ AT_YACC_IF.
+ Redefine AT_YYERROR_SEES_LOC_IF using it.
+ (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
+ not defined.
+ Don't use the location in yy::Parser::error_ and
+ yy::Parser::print_ when not %locations.
+ Activate more lalr1.cc tests.
+
+2003-02-19 Akim Demaille <akim@epita.fr>
+

+
+2003-02-19 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
+ error recovery, mixing with/without pops and discarding of the
+ lookahead.
+ Exercise YYERROR.
+ Disable the lalr1.cc tests as currently it doesn't support YYERROR.
+
+2003-02-17 Paul Eggert <eggert@twinsun.com>
+
+ * tests/atlocal.in (LDFLAGS, LIBS): New vars.
+ * tests/testsuite.at (AT_COMPILE): Use them.
+ This fixes the testsuite problem reported by Robert Lentz in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
+
+2003-02-12 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:

+ * tests/testsuite.at (AT_COMPILE_CXX): New.
+ * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
+ locations in a more synthetic way.
+ (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if
+ lalr1.cc is used.
+ Adjust the C locations to match those from Emacs: first column is
+ column 0.
+ Change all the expected results.
+ Conform to the GCS: simplify the locations when applicable.
+ (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)
+ (LEX_ARGS, USE_LEX_ARGS, LEX_PRE_FORMALS, LEX_PRE_ARGS): Replace

+
+2003-02-02 Akim Demaille <akim@epita.fr>

+
+ * po/LINGUAS: Add ms.
+
+2003-01-30 Akim Demaille <akim@epita.fr>
+
+ * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
+
+2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
+
+ * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+ of $1.
+
+ Changes in response to error report by S. Eken: GLR mode does not
+ handle negative $ indices or $ indices in embedded rules correctly.
+ See <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+ * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+ (b4_rhs_location): Ditto.
+ (yyfill): New function to copy from stack tree into array
+ incrementally.
+ (yyuserAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ Define YYFILL to use in user-defined actions to fill semantic array
+ as needed.
+ Remove dummy use of yystack, as there is now a guaranteed use.
+ (yydoAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ (yyresolveAction): Ditto.
+ (yyglrShiftDefer): Update comment.
+ (yyresolveStates): Use X == NULL for pointers, not !X.
+ (yyglrReduce): Ditto.
+ (yydoAction): Ditto
+
+ * tests/glr-regr1.at: Rename to ...

+2003-01-28 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc: Do not use @output_header_name@ unless

+ and <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
+
+2003-01-21 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+ we don't need to worry about yyerrlab1 being reported as an
+ "unused label" by non-GCC C compilers. The downside is that if
+ locations are used then a couple of statements are duplicated each
+ time YYERROR is invoked, but the upside is that the warnings
+ should vanish.
+ (yyerrlab1): Move code to YERROR.
+ (yyerrlab2): Remove. Change uses back to yyerrlab1.
+ This reverts some of the 2002-12-27 change.
+
+2003-01-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/output.c (symbol_printers_output): Fix typo that led
+ to core dump. Problem reported by Antonio Rus in
+ <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
+
+2003-01-13 Akim Demaille <akim@epita.fr>,
+ Quoc Peyrot <chojin@lrde.epita.fr>,
+ Robert Anisko <anisko_r@lrde.epita.fr>
+
+ * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
+ when the stacks contain one element, as the loop would otherwise
+ free the last state, and then use the top state (the one we just
+ popped). This means that the initial elements will not be freed
+ explicitly, as is the case in yacc.c; it is not a problem, as
+ these elements have fake values.
+
+2003-01-11 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: %expect-violations are now just warnings, reverting
+ to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
+ bootstrapping problem reported by Matthias Klose; see
+ <http://lists.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
+ * src/conflicts.c (conflicts_print): Likewise.
+ * tests/conflicts.at (%expect not enough, %expect too much,
+ %expect with reduce conflicts): Likewise.
+ * doc/bison.texinfo (Expect Decl): Document this. Also mention
+ that the warning is enabled if the number of conflicts changes
+ (not necessarily increases).
+
+ * src/getargs.c (version): Update copyright year.
+
+2003-01-09 Akim Demaille <akim@epita.fr>
+
+ * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
+
+2003-01-08 Paul Eggert <eggert@twinsun.com>
+
+ * Makefile.maint (WGETFLAGS):
+ New macro, containing "-C off" to disable proxy caches.
+ All uses of $(WGET) changed to $(WGET) $(WGETFLAGS).
+ (rel-check): Use $(WGET) instead of wget.
+
+2003-01-06 Paul Eggert <eggert@twinsun.com>
+
+ * doc/bison.texinfo (Generalized LR Parsing): Add a reference to
+ the GLR paper of Scott, Johnstone and Hussain.
+
+2003-01-04 Paul Eggert <eggert@twinsun.com>
+
+ * configure.ac (AC_ARG_ENABLE): Add --disable-yacc.
+ (YACC_SCRIPT, YACC_LIBRARY): New vars to AC_SUBST.
+ * lib/Makefile.am (lib_LIBRARIES): liby.a -> @YACC_LIBRARY@.
+ (EXTRA_LIBRARIES): New var, for liby.a.
+ * src/Makefile.am (bin_SCRIPTS): yacc -> @YACC_SCRIPT@.
+ (EXTRA_SCRIPTS): New var, for yacc.
+
+ * data/yacc.c (yyerrlab1): Omit attribute if __cplusplus is defined,
+ since GNU C++ (as of 3.2.1) does not allow attributes on labels.
+ Problem reported by Nelson H. F. Beebe.
+
+2003-01-03 Paul Eggert <eggert@twinsun.com>
+
+ * lib/obstack.h (__INT_TO_PTR) [__STDC__]: Cast result to
+ (void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
+ when compiling Bison 1.875's `bitset bset = obstack_alloc
+ (bobstack, bytes);'. Problem reported by Nelson H. F. Beebe.
+
+ * src/scan-skel.l (QPUTS): Omit redundant `;' from macro definition.
+ ([^@\n]): Renamed from [^@\n]+ so that the token buffer does not
+ grow to a huge size with typical invocation.
+
+ * lib/hash.c (_Bool, bool, false, true, __bool_true_false_are_defined):
+ Use the pattern recommended by Autoconf 2.57, except also protect
+ against double-definition.
+ * src/system.h: Likewise.
+ Portability issues reported by Nelson H. F. Beebe.
+
+ * data/glr.c (yybool): Renamed from bool, to avoid collisions in C.
+ All uses changed. Provide a definition in both C and C++.
+ (yytrue, yyfalse): Define even if defined (__cplusplus).
+
+ * lib/bitset_stats.c (bitset_stats_list): Remove unused var.
+ Reported by Nelson H. F. Beebe.
+
+ * src/scan-skel.l ("@oline@"): Output lineno+1, not lineno.
+
+2003-01-02 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (yyerrlab1): Append `;' after attribute, to
+ pacify the buggy "smart preprocessor" in MacOS 10.2.3.
+ Bug reported by Nelson H. F. Beebe.
+
+2003-01-01 Paul Eggert <eggert@twinsun.com>
+
+ * Version 1.875.
+
+2002-12-30 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (<INITIAL,SC_AFTER_IDENTIFIER,SC_PRE_CODE>","):
+ Moved here from...
+ (<INITIAL>","): Here. This causes stray "," to be treated
+ more uniformly.
+
+ * src/scan-gram.l (<SC_BRACED_CODE>"}"): Output ";" before the
+ last brace in braced code when not in Yacc mode, for compatibility
+ with Bison 1.35. This resurrects the 2001-12-15 patch to
+ src/reader.c.
+
+ * src/reader.h (YYDECL): Use YYSTYPE, not its deprecated alias
+ yystype. This follows up the 2002-12-24 YYSTYPE bug fix.
+
+2002-12-28 Paul Eggert <eggert@twinsun.com>
+
+ * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
+ that of SYM's type. This fixes Debian bug 168069, reported by
+ Thomas Olsson.
+
+2002-12-28 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75f.
+
+ Switch back to the Yacc style of conflict reports, undoing some
+ of the 2002-07-30 change.
+ * doc/bison.texinfo (Understanding): Use Yacc style for
+ conflict reports. Also, use new way of locating rules.
+ * src/conflicts.c (conflict_report):
+ Renamed from conflict_report_yacc, removing the old
+ 'conflict_report'. Translate the entire conflict report at once,
+ so that we don't assume that "," has the same interpretation in
+ all languages.
+ (conflicts_output): Use Yacc-style conflict report for each state,
+ instead of our more-complicated style.
+ (conflicts_print): Use Yacc-style conflict report, except print
+ the input file name when not emulating Yacc.
+ * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
+ Conflicted Reduction, %expect not enough, %expect too much,
+ %expect with reduce conflicts): Switch to Yacc-style conflict reports.
+ * tests/existing.at (GNU Cim Grammar): Likewise.
+ * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
+
+ * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
+ fatal): Don't invoke fflush; it's not needed and it might even be
+ harmful for stdout, as stdout might not be open.
+ * src/reduce.c (reduce_print): Likewise.
+
+2002-12-27 Paul Eggert <eggert@twinsun.com>
+
+ Fix a bug where error locations were not being recorded correctly.
+ This problem was originally reported by Paul Hilfinger in
+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
+
+ * data/yacc.c (yyparse): New local var yylerrsp, to record the
+ top of the location stack's error locations.
+ (yyerrlab): Set it. When discarding a token, push its location
+ onto yylerrsp so that we don't lose track of the error's end.
+ (yyerrlab1): Now is only the target of YYERROR, so that we can
+ properly record the location of the action that failed. For GCC
+ 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+ GCC warning about yyerrlab1 being unused if YYERROR is unused.
+ (yyerrlab2): New label, which yyerrlab now falls through to.
+ Compute the error's location by applying YYLLOC_DEFAULT to
+ the locations of all the symbols that went into the error.
+ * doc/bison.texinfo (Location Default Action): Mention that
+ YYLLOC_DEFAULT is also invoked for syntax errors.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Error locations include the locations of all the tokens that were
+ discarded, not just the last token.
+
+2002-12-26 Paul Eggert <eggert@twinsun.com>
+
+ * src/files.c: Include quote.h.
+ (compute_output_file_names): Warn if we detect conflicting
+ outputs to the same file. This should catch the misunderstanding
+ exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+ * src/conflicts.c (conflicts_print): If the user specifies
+ "%expect N", report an error if there are any reduce/reduce
+ conflicts. This is what the manual says should happen.
+ This fixes Debian bug 130890, reported by Anthony DeRobertis.
+ * tests/conflicts.at (%expect with reduce conflicts): New test.
+
+ Don't use m4_include on relative file names, as it doesn't work as
+ desired if there happens to be a file with that name under ".".
+
+ * m4sugar/version.m4: Remove; it was included but it wasn't used.
+ * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
+ * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
+ * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
+ * src/output.c (output_skeleton): Use full path names when
+ specifying a file to include; don't rely on include path, as
+ it's unreliable when the working file contains a file with
+ that name.
+
+2002-12-25 Paul Eggert <eggert@twinsun.com>
+
+ Remove obsolete references to bison.simple and bison.hairy.
+ Problem mentioned by Aubin Mahe in
+ <http://lists.gnu.org/archive/html/help-bison/2002-12/msg00010.html>.
+ * data/glr.c: Comment fix.
+ * doc/bison.1: Remove references. Also, mention "yacc".
+
+ * src/getargs.c (getargs) [MSDOS]: Don't assume optarg != NULL
+ with -g option.
+
+ * src/parse-gram.y (declaration): Use enum "report_states" rather
+ than its numeric value 1.
+
+ * src/scan-skel.l ("@output ".*\n): Close any old yyout before
+ opening a new one. This fixes Debian bug 165349, reported by
+ Bruce Stephens.
+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75e.
+
+ * Makefile.maint (cvs-update): Don't assume that the shell
+ supports $(...), as Solaris sh doesn't.
+
+ * src/parse-gram.y (lloc_default): Remove test for empty
+ nonterminals at the end, since it didn't change the result.
+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ If the user does not define YYSTYPE as a macro, Bison now declares it
+ using typedef instead of defining it as a macro. POSIX requires this.
+ For consistency, YYLTYPE is also declared instead of defined.
+
+ %union directives can now have a tag before the `{', e.g., the
+ directive `%union foo {...}' now generates the C code
+ `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+ The default union tag is `YYSTYPE', for compatibility with Solaris 9
+ Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
+ instead of `yyltype'.
+
+ `yystype' and `yyltype' are now obsolescent macros instead of being
+ typedefs or tags; they are no longer documented and will be
+ withdrawn in a future release.
+
+ * data/glr.c (b4_location_type): Remove.
+ (YYSTYPE): Renamed from yystype.
+ (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
+ (struct YYLTYPE): Renamed from struct yyltype.
+ (YYLTYPE): Renamed from yyltype.
+ (yyltype, yystype): New (and obsolescent) macros,
+ for backward compatibility.
+ * data/yacc.c: Likewise.
+
+ * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
+ does not specify a union tag. This is for compatibility with
+ Solaris 9 yacc.
+
+ * src/parse-gram.y (add_param): 2nd arg is now char * not char
+ const *, since it is now modified by stripping surrounding { }.
+ (current_braced_code): Remove.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
+ PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
+ trailing " {...}". Now of type <chars>.
+ (grammar_declaration): Adjust to bundled tokens.
+ (code_content): Remove; stripping is now done by add_param.
+ (print_token_value): Print contents of bundled tokens.
+ (token_name): New function.
+
+ * src/reader.h (braced_code, current_braced_code): Remove.
+ (token_name): New decl.
+
+ * src/scan-gram.l (handle_dollar, handle_at): Now takes int
+ token_type, not braced_code code_kind. All uses changed.
+ (SC_PRE_CODE): New state, for scanning after a keyword that
+ has (or usually has) an immediately-following braced code.
+ (token_type): New local var, to keep track of which token type
+ to return when scanning braced code.
+ (<INITIAL>"%destructor", <INITIAL>"%lex-param",
+ <INITIAL>"%parse-param", <INITIAL>"%printer",
+ <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
+ instead of returning a token type immediately.
+ (<INITIAL>"{"): Set token type.
+ (<SC_BRACED_CODE>"}"): Use it.
+ (handle_action_dollar, handle_action_at): Now returns bool
+ indicating success. Fail if ! current_rule; this prevents a core dump.
+ (handle_symbol_code_dollar, handle_symbol_code_at):
+ Remove; merge body into caller.
+ (handle_dollar, handle_at): Complain in invalid contexts.
+
+ * NEWS, doc/bison.texinfo: Document the above.
+ * NEWS: Fix years and program names in copyright notice.
+
+2002-12-17 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS, doc/bison.texinfo (Parser Function, Pure Calling, Error
+ Reporting, Table of Symbols): Omit mentions of %lex-param and
+ %parse-param from the documentation for now.
+
+2002-12-15 Paul Eggert <eggert@twinsun.com>
+
+ Undo most of the 2002-11-12 yychar -> yytoken patch, as it broke
+ GCC 3.2.1 (which depends on yychar == YYEMPTY when there is no
+ lookahead symbol, and which sets yychar in parser actions) and it
+ disagreed with the Bison documentation. Bug
+ reported by Andrew Walrond.
+
+ * data/yacc.c (YYTRANSLATE): Don't check for negative argument,
+ as the caller now does that.
+ (yyclearin, YYBACKUP, yyparse): Use yychar, not yytoken.
+ (YYEMPTY): Parenthesize right hand side, since others use it.
+ (yyparse): Don't assume that our generated code is the only code
+ that sets yychar.
+
+2002-12-13 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75d.
+
+ POSIX requires a "yacc" command.
+ * src/Makefile.am (bin_SCRIPTS): New macro, for yacc.
+ (MOSTLYCLEANFILES): Add yacc.

+ * doc/bison.texinfo (Invocation, Bison Options): Mention yacc
+ as an alias for bison y.
+

+ * lib/alloca.c, lib/error.c, lib/getopt.c, lib/getopt.h
+ lib/getopt1.c, lib/gettext.h, lib/memrchr.c, lib/obstack.c,

+
+ Fix a bad interaction with flex 2.5.23 reported by Bruce Lilly in
+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00114.html>.
+ * data/yacc.c (YYLTYPE, struct yyltype): Do not define unless
+ locations are requested.
+ (union yyalloc): Do not depend on YYLTYPE_IS_TRIVIAL unless
+ locations are requested.
+
+2002-12-12 Paul Eggert <eggert@twinsun.com>
+
+ Remove unportable casts and storage allocation tricks.
+ While we're at it, remove almost all casts, since they
+ usually aren't needed and are a sign of trouble.
+
+ * configure.ac (AC_CHECK_TYPES): Check for uintptr_t.
+
+ * src/derives.c (derives_compute): Do not subtract NTOKENS from
+ the pointer DSET returned by malloc; this isn't portable.
+ Instead, always use DSET[i - NTOKENS] rather than DSET[i].
+ Similarly for DERIVES.
+ * src/lalr.c (set_goto_map): Likewise, for GOTO_MAP and TEMP_MAP.
+ * src/nullable.c (nullable_compute): Likewise, for RSETS and NULLABLE.
+ * src/reduce.c (reduce_grammar_tables): Likewise, for nontermmap
+
+ * src/derives.c (derives_compute): Do not bother invoking

+ rather than XMALLOC (char, N).
+
+ * src/files.c (filename_split): Rewrite to avoid cast.
+
+ * src/gram.h (symbol_number_as_item_number,
+ item_number_as_symbol_number, rule_number_as_item_number,

+ Now inline functions rather than macros, to avoid casts.
+ * src/state.h (state_number_as_int): Likewise.
+ * src/tables.c (state_number_to_vector_number,
+ symbol_number_to_vector_number): Likewise.
+
+ * src/gram.h (int_of_rule_number): Remove; no longer used.
+
+ * src/lalr.c (add_lookback_edge): Use malloc rather than calloc,

+
+ * src/main.c (alloca) [C_ALLOCA]: Add decl here, the only place

+ Likewise.
+ * src/uniqstr.c (uniqstrs_new, hash_initialize, uniqstrs_do): Likewise.
+
+ * src/output.c (GENERATE_MUSCLE_INSERT_TABLE): Use long local

+ have to worry about alloca.
+ * src/state.c (state_hash_lookup): Likewise.
+
+ * src/scan-gram.l (<SC_ESCAPED_CHARACTER>"'"): Use unsigned char
+ local var instead of casting to unsigned char, to avoid casts.

+2002-12-09 Paul Eggert <eggert@twinsun.com>
+
+ Change identifier spellings to avoid collisions with names
+ that are reserved by POSIX.
+
+ Don't use names ending in _t, since POSIX reserves them.
+ For consistency, remove _e and _s endings -- they're weren't

+2002-12-08 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
+ since this causes problems when __file__ contains character

+2002-12-06 Paul Eggert <eggert@twinsun.com>
+
+ Add support for rules that do not have trailing semicolons, as
+ POSIX requires. Improve the quality of locations in Bison

+ GNU Coding Standards for locations that span file boundaries.
+ * src/location.h: Do not include <quotearg.h>; no longer needed.

+ of *loc.
+ (STEP): Remove. No longer needed, now that adjust_location does
+ the work. All uses removed.
+ (scanner_cursor): New var.

+ Don't bother testing for CR.
+ (handle_syncline): Remove location arg; now updates scanner cursor.

+ (<INITIAL>"%{", "{", "%%"): Save code_start.
+ (<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
+ (<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):

+
+2002-12-06 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
+ promotes to int; it might be unsigned int.
+ * data/yacc.c (yy_reduce_print): Likewise.
+
+ * doc/bison.texinfo (Table of Symbols): YYERROR_VERBOSE should
+ be #defined in the prologue, not in the Bison declarations.
+ This fixes Debian Bug 102878, reported by Shaul Karl.
+
+2002-12-02 Paul Eggert <eggert@twinsun.com>
+
+ * configure.ac (AC_REPLACE_FUNCS): Add strtoul.

+
+2002-11-30 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (no_cr_read, extend_location): Move to epilogue,
+ and put only a forward declaration in the prologue. This is for

+ Type clashes now generate warnings, not errors, since it
+ appears that POSIX may allow some grammars with type clashes.
+ * src/reader.c (grammar_current_rule_check): Warn about

+
+2002-11-29 Paul Eggert <eggert@twinsun.com>
+
+ * doc/bison.texinfo: Emphasize that yylex and yyerror must
+ be declared before being used. E.g., one should typically
+ declare them in the prologue. Use GNU coding style in examples.
+ Put "const" consistently after the type it modifies. Mention
+ that C99 supports "inline". Mention that yyerror traditionally
+ returns "int".
+
+ %parse-param and %lex-param now take just one argument, the
+ declaration; the argument name is deduced from the declaration.
+
+ * doc/bison.texinfo (Parser Function, Pure Calling, Error
+ Reporting, Table of Symbols): Document this.
+ * src/parse-gram.y (add_param): New function.
+ (COMMA): Remove.
+ (declaration): Implement new rule for %parse-param and %lex-param.
+ * src/scan-gram.l: "," now elicits a warning, rather than being
+ a token; this is more compatible with byacc.
+ * tests/calc.at (Simple LALR Calculator): Adopt new convention.
+
+2002-11-27 Paul Eggert <eggert@twinsun.com>
+
+ Rename identifiers to avoid real and potential collisions.
+
+ * data/c.m4 (b4_yysymprint_generate): yyout -> yyoutput,

+ (YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
+ The name "yycontrol" violates the name space rules, and this stuff
+ wasn't being used anyway.
+ (input): Remove action; this stuff wasn't being used.
+ (gram_error): Rename local variable yylloc -> loc.
+ * src/reader.h (struct gram_control_s, gram_control_t): Remove.
+ (YY_DECL): Don't use "yy" at start of local variables.

+ * src/scan-gram.l (STEP): Renamed from YY_STEP. All uses changed.
+ (STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
+ (STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.

+
+2002-11-24 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75c.
+

+ Test the position of the ';' token too.
+ (Printers and Destructors): Likewise.
+ (Printers and Destructors: %glr-parser): Remove for now, to avoid
+ unnecessarily alarming people when the test fails.
+
+ * data/yacc.c (yyerrlab1): Move this label down, so that the
+ parser does not discard the lookahead token if the user code
+ invokes YYERROR. This change is required for POSIX conformance.
+
+ * lib/error.c: Sync with gnulib.
+
+2002-11-22 Paul Eggert <eggert@twinsun.com>

+
+ Avoid use of <assert.h>, as the GNU Coding Standards hint that one

+
+ * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.

+
+2002-11-18 Paul Eggert <eggert@twinsun.com>
+
+ * data/glr.c (yygetLRActions): Replace `yyindex' with

+
+2002-11-18 Akim Demaille <akim@epita.fr>

+ From Tim Van Holder.
+
+2002-11-17 Paul Eggert <eggert@twinsun.com>

+
+ * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
+ not define to {}, since this breaks the common use of `YYDPRINTF

+ Work around GCC warnings by surrounding corresponding calls with
+ {} if needed.
+ (yyhasResolvedValue): Remove unused function.

+
+ * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):

+ file twice in the grammar, as an extra check.
+
+ * tests/input.at (Torturing the Scanner): Surround the
+ backslash-newline tests with "#if 0", to make it less likely that

+
+2002-11-13 Paul Eggert <eggert@twinsun.com>
+
+ Fix some bugs reported by Albert Chin-A-Young in

+
+ * tests/input.at (Torturing the Scanner): Remove lines containing

+
+2002-11-12 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75b.
+
+ * data/glr.c (yydoAction): Return YYRESULTTAG, not int.

+
+ * Makefile.maint (po-check): Scan .l and .y files instead of the

+ Look for N_ as well as for _. Try to avoid matching #define for

+
+ Revamp to fix many (but not all) of the C- and M4-related quoting
+ problems. Among other things, this fixes the Bison bug reported
+ by Jan Hubicka when processing the Bash grammar; see:
+ <http://lists.gnu.org/archive/html/bison-patches/2002-11/msg00039.html>
+
+ Use new @ escapes consistently. Represent brackets with @{ and @}
+ rather than @<:@ and @:>@, since this works a bit better with dumb
+ editors like vi. Represent @ with @@, since @ is now consistently
+ an escape. Use @oline@ and @ofile@ rather than __oline__ and
+ __ofile__, to avoid unexpected expansions. Similarly, use @output
+ rather than #output.
+
+ * data/c.m4 (b4_copyright): Omit file name from comment, since
+ the file name could contain "*/".
+ (b4_synclines_flag): Don't quote the 2nd argument; it should already
+ be quoted. All uses changed.
+
+ * data/glr.c: Use new @ escapes consistently.
+ (b4_input_suffix, b4_output_parser_suffix, b4_output_parser_name,

+ * data/yacc.c: Likewise.
+
+ * src/files.c (output_infix): Remove; all uses removed.
+ * src/files.h: Likewise.

+ mishandled funny characters in file names, and anyway it isn't
+ needed any more.
+ * data/yacc.c: Likewise.
+ * data/lalr1.cc: Use YYSLP_NEEDED instead of b4_header_guard.
+
+ * data/glr.c (YYSTYPE_IS_TRIVIAL): Define when the .h file would.
+ * data/yacc.c: Likewise.
+
+ * src/muscle_tab.c: Include quotearg.h, since we need to quote C

+ (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.

+ * src/reader.c (prologue_augment, epilogue_set): Likewise.
+
+ * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash

+ (<SC_COMMENT,SC_LINE_COMMENT,SC_STRING,SC_CHARACTER,SC_BRACED_CODE,
+ SC_PROLOGUE,SC_EPILOGUE>): Escape $ and @, too.
+ Use new escapes @{ and @} for [ and ].
+
+ * src/scan-skel.l (yylineno, yyoutname): Remove static vars, replacing
+ them with auto vars.
+ Switch to new escape scheme, where @ is the escape character uniformly.
+ Abort if a stray escape character is found. Avoid unbounded input
+ buffer when parsing non-escaped text.
+
+ * tests/input.at (Torturing the Scanner): Add tests that @oline@,
+ __oline__, #output, $@, and @{ do not have unintended meanings.
+
+2002-11-09 Paul Eggert <eggert@twinsun.com>
+
+ Fix the test failure due to GCC warnings described in
+ <http://lists.gnu.org/archive/html/bug-bison/2002-11/msg00000.html>.
+ * data/glr.c (yyis_pact_ninf, yyis_table_ninf): New macros, which
+ evaluate to 0 if it's impossible for NINF to be in the respective
+ table.
+ (yygetLRActions, yyrecoverParseError): Use them.
+
+ * src/scan-gram.l (unexpected_end_of_file): Fix bug: columns were
+ counted in the token inserted at end of file. Now takes
+ location_t *, not location_t, so that the location can be
+ adjusted. All uses changed.
+
+ * tests/regression.at (Invalid inputs): Adjust wording in
+ diagnostic to match the new behavior.
+
+ * tests/torture.at (AT_DATA_TRIANGULAR_GRAMMAR,
+ AT_DATA_HORIZONTAL_GRAMMAR, AT_DATA_LOOKAHEADS_GRAMMAR,
+ AT_DATA_STACK_TORTURE): Replace `assert (x);' with `if (! (x))
+ abort ();'. This reduces the runtime of the "Many lookaheads"
+ test from 27.6 to 2.7 minutes on a 440 MHz Ultrasparc III running
+ GCC 3.2.
+
+2002-11-07 Paul Eggert <eggert@twinsun.com>
+
+ * src/parse-gram.y (CHARACTER): Remove unused token.
+ All uses removed.
+
+ * src/scan-gram.l: Remove stack option. We no longer use the
+ stack, since the stack was never deeper than 1; instead, use the
+ new auto var c_context to record the stacked value.
+
+ Remove nounput option. At an unexpected end of file, we now unput
+ the minimal input necessary to end cleanly; this simplifies the
+ code.
+
+ Avoid unbounded token sizes where this is easy.
+
+ (unexpected_end_of_file): New function.
+ Use it to systematize the error message on unexpected EOF.
+ (last-string): Now auto, not static.
+ (YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
+ (scanner_last_string_free): Remove; not used.
+ (percent_percent_count): Move decl to just before use.

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

+
+ Do not use "struct bitset_struct" to mean different things in

+ * tests/bison.in, tests/atlocal.in: Adjust to CVS Autoconf.
+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * src/parse-skel.y (process_skeleton): Don't bind the parser's
+ tracing code to --trace, wait for a better --trace option, with
+ args.
+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple (YYSTDERR): Remove, replace `stderr'.
+ The ISO C++ standard is extremely clear about it: stderr is
+ considered a macro, not a regular symbol (see table 94 `Header
+ <cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
+ Therefore std:: does not apply to it. It still does with fprintf.
+ Also, s/cstdio.h/cstdio/.
+
+2002-01-03 Akim Demaille <akim@epita.fr>
+
+ * lib/quotearg.c: Use `#include "..."' instead of `#include <...>'
+ for non system headers.
+
+2002-01-02 Akim Demaille <akim@epita.fr>
+
+ Equip the skeleton chain with location tracking, runtime trace,
+ pure parser and scanner.
+
+ * src/parse-skel.y: Request a pure parser, locations, and prefix
+ renaming.
+ (%union): Having several members with the same type does not help
+ type mismatches, simplify.
+ (YYPRINT, yyprint): New.
+ (yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
+ (skel_error): this.
+ Handle locations.
+ * src/scan-skel.l: Adjust to these changes.
+ * src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
+ (LOCATION_PRINT, skel_control_t): New.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/parse-skel.y: Get rid of the shift/reduce conflict:
+ replace `gb' with BLANKS.
+ * src/scan-skel.l: Adjust.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/system.h: We don't need nor want bcopy.
+ Throw away MS-DOS crap: we don't need getpid.
+ * configure.in: We don't need strndup. It was even causing
+ problems: because Flex includes the headers *before* us,
+ _GNU_SOURCE is not defined by config.h, and therefore strndup was
+ not visible.
+ * lib/xstrndup.c: New.
+ * src/scan-skel.l: Use it.
+ Be sure to initialize yylval.muscle member when scanning a MUSCLE.
+ * src/parse-skel.y: Use %directives instead of #defines.
+
+2001-12-30 Akim Demaille <akim@epita.fr>
+
+ * src/skeleton.h: New.
+ * src/output.c (output_parser, output_master_parser): Remove, dead
+ code.
+ * src/output.h (get_lines_number, actions_output, guards_output)
+ (token_definitions_output): Prototype them.
+ * src/parse-skel.y: Add the license notice.
+ Include output.h and skeleton.h.
+ (process_skeleton): Returns void, and takes a single parameter.
+ * src/scan-skel.l: Add the license notice.
+ Include skeleton.h.
+ Don't use %option yylineno: it seems that then Flex imagines
+ REJECT has been used, and therefore it won't reallocate its
+ buffers (which makes no other sense to me than a bug). It results
+ in warnings for `unused: yy_flex_realloc'.

+2001-12-30 Robert Anisko <robert.anisko@epita.fr>
+
+ * src/muscle_tab.h (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+ (MUSCLE_INSERT_PREFIX): ...to there.
+ * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+ (MUSCLE_INSERT_PREFIX): Move from here...
+
+ * src/bison.hairy: Add a section directive. Put braces around muscle
+ names. This parser skeleton is still broken, but Bison should not
+ choke on a bad muscle 'syntax'.
+ * src/bison.simple: Add a section directive. Put braces around muscle
+ names.
+
+ * src/files.h (strsuffix, stringappend): Add declarations.
+ (tab_extension): Add declaration.
+ (short_base_name): Add declaration.
+
+ * src/files.c (strsuffix, stringappend): No longer static. These
+ functions are used in the skeleton parser.
+ (tab_extension): New.
+ (compute_base_names): Use the computations done in this function
+ to guess if the generated parsers should have '.tab' in their
+ names.
+ (short_base_name): No longer static.
+
+ * src/output.c (output_skeleton): New.
+ (output): Disable call to output_master_parser, and give a try to
+ a new skeleton handling system.
+ (guards_output, actions_output): No longer static.
+ (token_definitions_output, get_lines_number): No longer static.
+
+ * configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
+
+ * src/Makefile.am (bison_SOURCES): Add scan-skel.l and
+ parse-skel.y.
+
+ * src/parse-skel.y: New file.
+ * src/scan-skel.l: New file.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ %name-prefix is broken.
+
+ * src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
+ Adjust all dependencies.
+ * tests/headers.at (export YYLTYPE): Strengthen this test: use
+ %name-prefix.
+
+ Renaming yylval but not yylloc is not consistent. Now we do.
+
+ * src/bison.simple: Prefix yylloc if used.
+ * doc/bison.texinfo (Decl Summary): Document that.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Promote `%long-directive' over
+ `%long_directive'.
+ Remove all references to fixed-output-files, yacc is enough.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple: Define YYDEBUG and YYERROR_VERBOSE *after* the
+ user prologue. These are defaults.
+ * tests/actions.at (Mid-rule actions): Make sure the user can
+ define YYDEBUG and YYERROR_VERBOSE.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (header_output): Don't forget to export YYLTYPE and
+ yylloc.
+ * tests/headers.at (export YYLTYPE): New, make sure it does.
+ * tests/regression.at (%union and --defines, Invalid CPP headers):
+ Move to...
+ * tests/headers.at: here.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h (rule_s): Member `assoc' is of type `associativity'.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/actions.at (Mid-rule actions): Output on a single line
+ instead of several.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Formatting changes.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Don't store the token defs in a muscle, just be ready to output it
+ on command. Now possible via `symbols'. Fixes a memory leak.
+
+ * src/output.c (token_definitions_output): New.
+ (output_parser, header_output): Use it.
+ * src/reader.c (symbols_save): Remove.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/bison.simple: Do not provide a default for YYSTYPE and
+ YYLTYPE before the user's prologue. Otherwise it's hardly... a
+ default.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Mid-rule actions are simply... ignored!
+
+ * src/reader.c (readgram): Be sure to attach mid-rule actions to

+ rule.
+ * tests/actions.at (Mid-rule actions): New.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Memory leak.
+
+ * src/reader.c (reader): Free grammar.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Memory leak.
+
+ * src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
+ since it allocates it for each state, although only one is needed.
+ (allocate_storage): Do it here.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/options.h, src/options.c (create_long_option_table): Rename
+ as...
+ (long_option_table_new): this, with a clearer prototype.
+ (percent_table): Remove, unused,
+ * src/getargs.c (getargs): Adjust.
+
+2001-12-29 Akim Demaille <akim@epita.fr>

+ as states.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (build_relations): Rename `states' as `states1'.
+ Sorry, I don't understand exactly what it is, no better name...

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.c (rprec, rprecsym, rassoc): Remove, unused since long
+ ago.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c, src/reader.h (user_toknums): Remove.
+ Adjust all users to use symbols[i]->user_token_number.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.c, src/gram.h (sprec, sassoc): Remove.

+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c, src/reader.h (tags): Remove.
+ Adjust all users to use symbols[i]->tag.

+ * src/reader.c (packsymbols): Fill this table.
+ Drop sprec.
+ * src/conflicts.c (resolve_sr_conflict): Adjust.
+ * src/reduce.c (reduce_grammar): Adjust: just sort symbols, a

+ Use symbols[i]->tag instead of tags[i].
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (_AT_DATA_CALC_Y): Also use %union.
+ In addition, put a comment in there, to replace...
+ * tests/regression.at (%union and C comments): Remove.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Actions): Blindly move the actual
+ output as expected output. The contents *seem* right to me, but I
+ can't pretend reading perfectly parser tables... Nonetheless, all
+ the other tests pass correctly, the table look OK, even though the
+ presence of `$axiom' is to be noted: AFAICS it is useless (but
+ harmless).
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Don't add the rule 0 if there were no
+ rules read. In other words, add it _after_ having performed
+ grammar sanity checks.
+ Fixes the `tests/regression.at (Invalid input: 1)' Failure.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
+ visible, and some states have now a different number.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Bind the initial rule's lineno to that
+ of the first rule.
+ * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
+ (Solved SR Conflicts): Adjust rule 0's line number.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ Fix the `GAWK Grammar' failure.
+
+ * src/LR0.c (final_state): Initialize to -1 so that we do compute
+ the reductions of the first state which was mistakenly confused
+ with the final state because precisely final_state was initialized
+ to 0.
+ * tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
+ now noticed by Bison.
+ * tests/regression.at (Rule Line Numbers): Adjust: state 0 does
+ have a reduction on $default.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/gram.c (ritem_print): Be sure to subtract 1 when displaying

+ now.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (lookaheads_print): New.
+ (lalr): Call it when --trace-flag.
+ * tests/sets.at (Nullable): Adjust: when tracing, the lookaheads
+ are dumped.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',
+ when walking through ritem, even via rule->rhs.
+ * src/reduce.c (dump_grammar, useful_production, reduce_output)
+ (useful_production, useless_nonterminals): Likewise.
+ (reduce_grammar_tables): Likewise, plus update nritems.
+ * src/nullable.c (set_nullable): Likewise.
+ * src/lalr.c (build_relations): Likewise.
+ * tests/sets.at (Nullable): Adjust.
+ Fortunately, now, the $axiom is no longer nullable.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (generate_states): Use nritems, not nitems, nor using

+
+ * src/output.c: Comment changes.
+
+2001-12-27 Paul Eggert <eggert@twinsun.com>
+
+ * src/bison.simple (YYSTACK_ALLOC, YYSIZE_T): Remove special
+ cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
+ Sparc, as they were causing more porting problems than the
+ (minor) performance improvement was worth.
+
+ Also, catch up with 1.31's YYSTD.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output_gram): Rely on nritems, not the
+ 0-sentinel. See below.
+ Use -1 as separator, not 0.
+ * src/bison.simple (yyparse): Subtract 1 to the rule numbers.
+ Rely on -1 as separator in yyrhs, instead of 0.
+ * tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
+ twice `Now at end of input', therefore there are two lines less to
+ expect.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Unresolved SR Conflicts):
+ (Solved SR Conflicts, Rule Line Numbers): Adjust to the changes
+ below.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (new_state): Recognize the final state by the fact it
+ is reached by eoftoken.
+ (insert_start_shifting_state, insert_eof_shifting_state)
+ (insert_accepting_state, augment_automaton): Remove, since now
+ these states are automatically computed from the initial state.
+ (generate_states): Adjust.
+ * src/print.c: When reporting a rule number to the user, substract
+ 1, so that the axiom rule is rule 0, and the first user rule is 1.
+ * src/reduce.c: Likewise.
+ * src/print_graph.c (print_core): For the time being, just as for
+ the report, depend upon --trace-flags to dump the full set of
+ items.
+ * src/reader.c (readgram): Once the grammar read, insert the rule
+ 0: `$axiom: START-SYMBOL $'.
+ * tests/set.at: Adjust: rule 0 is now displayed, and since the
+ number of the states has changed (the final state is no longer
+ necessarily the last), catch up.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ Try to make the use of the eoftoken valid. Given that its value
+ is 0 which was also used as a sentinel in ritem, (i) make sure >= 0
+ is used instead of > 0 where appropriate, (ii), depend upon nritems
+ instead of the 0-sentinel.
+
+ * src/gram.h, src/gram.c (nritems): New.
+ Expected to be duplication of nitems, but for the time being...
+ * src/reader.c (packgram): Assert nritems and nitems are equal.
+ * src/LR0.c (allocate_itemsets, new_itemsets): Adjust.
+ * src/closure.c (print_closure, print_fderives): Likewise.

+ reductions, then output the report anyway if requested, then die.
+ * src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
+ * src/reader.c (eoftoken): New.
+ (parse_token_decl): If the token being defined has value `0', it
+ is the eoftoken.
+ (packsymbols): No longer hack `tags' to insert `$' by hand.
+ Be sure to preserve the value of the eoftoken.
+ (reader): Make sure eoftoken is defined.
+ Initialize nsyms to 0: now eoftoken is created just like the others.
+ * src/print.c (print_grammar): Don't special case the eof token.
+ * src/regression.at: Adjust: `$' has value 0, not -1, which was a
+ lie anyway, albeit pleasant.
+ * tests/calc.at: Exercise error messages with eoftoken.
+ Change the grammar so that empty input is invalid.
+ Adjust expectations.
+ When yyungeting, be sure to use a valid yylloc: use last_yylloc.
+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * configure.in: Check the protos of strchr ans strspn.
+ Replace strchr if needed.

+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/print.c, src/print_graph.c (escape): New.
+ Use it to quote the TAGS outputs.
+ * src/print_graph.c (print_state): Now errors are in red, and
+ reductions in green.
+ Prefer high to wide: output the state number on a line of its own.

+
+ * src/state.h, src/state.c (reductions_new): New.

+ * src/reader.c (parse_braces): New, factoring...

+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/gram.h (rule_t): `guard' and `guard_line' are new members.
+ * src/reader.c (symbol_list): `guard' and `guard_line' are new
+ members.
+ (symbol_list_new): Adjust.
+ (copy_action): action_line is the first line, not the last.
+ (copy_guard): Just as for actions, store the `action' only, not
+ the switch/case/break flesh.
+ Don't parse the user action that might follow the guard, let...
+ (readgram): do it, i.e., now, there can be an action after a
+ guard.
+ In other words the guard is just explicitly optional.
+ (packgram): Adjust.
+ * src/output.c (guards_output): New.
+ (output_parser): Call it when needed.
+ (output): Also free the guard and attrs obstacks.
+ * src/files.c, src/files.h (obstack_save): Remove.
+ (output_files): Remove.
+ As a result, if one needs the former `.act' file, using an
+ appropriate skeleton which requires actions and guards is now
+ required.
+ * src/main.c (main): Adjust.
+ * tests/semantic.at: New.
+ * tests/regression.at: Use `input.y' as input file name.
+ Avoid 8+3 problems by requiring input.c when the test needs the

+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ All the hacks using a final pseudo state are now useless.
+
+ * src/LR0.c (set_state_table): state_table holds exactly nstates.

+ (initialize_LA, compute_lookaheads, initialize_lookaheads): Use it

+
+2001-12-27 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (action_row, token_actions): Use a state_t instead

+ (count_sr_conflicts, count_rr_conflicts, conflicts_output)
+ (conflicts_print, print_reductions): Use a state_t instead of an
+ integer when referring to a state.
+ As much as possible, depend upon nlookaheads, instead of the
+ `lookaheadsp' member of the following state (since lookaheads of
+ successive states are successive, the difference between state n + 1
+ and n served as the number of lookaheads for state n).

+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ * src/nullable.c (set_nullable): Useless rules must be skipped,

+2001-12-15 Akim Demaille <akim@epita.fr>

+ Suggested by Arnold Robbins and Tom Tromey.
+
+2001-12-14 Akim Demaille <akim@epita.fr>

+
+2001-12-14 Akim Demaille <akim@epita.fr>
+

+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ The computation of nullable is broken: it doesn't handle empty

+
+ * tests/torture.at (GNU AWK Grammar): New.
+ * tests/sets.at (Nullable): New.
+ * src/nullable.c (set_nullable): Instead of blindly looping over
+ `ritems', loop over the rules, and then over their rhs's.
+
+ Work around Autotest bugs.
+
+ * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
+ frame, because Autotest understand lines starting with a `+' as
+ traces from the shell. Then, they are not processed properly.
+ Admittedly an Autotest bug, but we don't have time to wait for
+ Autotest to catch up.
+ * tests/regression.at (Broken Closure): Adjust to the new table

+ Move to...
+ * tests/sets.at: here.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+

+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * src/print.c (print_actions): Output the handling of `$' as the
+ traces do: shifting the token EOF. Before EOF was treated as a
+ nonterminal.
+ * tests/regression.at: Adjust some tests.
+ * src/print_graph.c (print_core): Complete the set of items via
+ closure. The next-to-final and final states are still unsatisfying,
+ but that's to be addressed elsewhere.
+ No longer output the rule numbers, but do output the state number.
+ A single loop for the shifts + gotos is enough, but picked a
+ distinct color for each.
+ (print_graph): Initialize and finalize closure.
+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Remove dead code, an strip useless

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/state.h (shifts): Remove the `number' member: shifts are
+ attached to state, hence no longer need to be labelled with a
+ state number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of
+ shifts is useless: just fill directly the state's shifts member.
+
+ * src/state.h (shifts): Remove the `next' member.
+ * src/LR0.c (first_state, last_state): Remove.
+ Adjust the callers.
+ (augment_automaton): Don't look for the shifts that must be added
+ a shift on EOF: it is those of the state we looked for! But now,
+ since shifts are attached, it is no longer needed to looking
+ merely by its id: its number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Better variable locality.
+ Remove an impossible branch: if there is a state corresponding to
+ the start symbol being shifted, then there is shift for the start
+ symbol from the initial state.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'

+ * tests/regression.at (Rule Line Numbers): Adjust.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Now that all states have shifts,

+
+ * src/LR0.h (first_shift, first_reduction): Remove.
+ * src/lalr.c: Don't use first_shift: find shifts through the

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c: Attach shifts to states as soon as they are
+ computed.

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (insert_start_shift): Rename as...
+ (insert_start_shifting_state): this.
+ (insert_eof_shifting_state, insert_accepting_state): New.
+ (augment_automaton): Adjust.
+ Better locality of the variables.
+ When looking if the start_symbol is shifted from the initial
+ state, using `while (... symbol != start_symbol ...)' sounds
+ better than `while (... symbol < start_symbol ...)': If fail
+ to see how the order between symbols could be relevant!
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.h: Don't declare `spec_name_prefix' and
+ `spec_file_prefix', declared by src/files.h.
+ * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
+ * src/muscle_tab.c (muscle_init): Default prefix to NULL.
+ * src/output.c (prepare): Adjust.
+ * src/reader.c (symbols_output): Likewise.
+ * src/vmsgetargs.c: Vaguely adjust, but who cares?
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/muscle_tab.c (muscle_init): NULL is a better default than
+ `"0"'.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (reader): Calling symbols_output once is enough.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of
+ reductions is useless: just fill directly the state's reductions

+
+ * src/state.h (struct reductions): Remove member `number' and

+ * src/LR0.c (first_reduction, last_reduction): Remove.
+ (save_reductions): Don't link the new reductions, store them in
+ this_state.
+ * src/lalr.c (set_state_table): No need to attach reductions to

+ * src/output.c (output_actions): No longer free the shifts, then
+ the reductions, then the states: free all the states and their
+ members.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/options.c (OPTN, DRTV, BOTH): New.
+ (option_table): Use them.
+
+ * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
+ the job of system.h.
+ * src/options.c: Don't include stdio.h and xalloc.h for the same
+ reasons.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Clean up GCC warnings.

+ * tests/Makefile.am: Adjust.
+
+2001-12-10 Akim Demaille <akim@epita.fr>

+
+ New experimental feature: if --verbose --trace output all the

+
+ * src/print.c (print_core): If `trace_flag', then invoke closure

+ (print_results): Invoke new_closure/free_closure if needed.
+
+2001-12-05 Akim Demaille <akim@epita.fr>
+

+
+2001-12-05 Akim Demaille <akim@epita.fr>
+

+
+ (yyparse): Don't dump core if alloca or malloc fails; instead, report
+ a parser stack overflow. Allocate just one block of memory for all
+ three stacks, instead of allocating three blocks; this typically is
+ faster and reduces fragmentation.
+
+ Do not limit the number of items in the stack to a value that fits

+
+2000-10-02 Paul Eggert <eggert@twinsun.com>
+
+ * bison.s1 (yyparse): Assign the default value

+
+ The location tracking mechanism is precious for parse error
+ messages. Nevertheless, it is enabled only when `@n' is used in
+ the grammar, which is a different issue (you can use it in error
+ message, but not in the grammar per se). Therefore, there should
+ be another means to enable it.
+
+ * src/getargs.c (getargs): Support `--locations'.
+ (usage): Report it.
+ * src/getargs.h (locationsflag): Export it.
+ * src/lex.c (percent_table): Support `%locations'.
+ * src/reader.c (yylsp_needed): Remove this variable, now replaced
+ with `locationsflag'.
+ * doc/bison.texinfo: Document `--locations' and `%locations'.
+ Sort the options.
+ * tests/calc.m4: Test it.
+
+ For regularity of the names, replace each
+ (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
+ (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
+ In addition replace each `flag' with `_flag'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Also test parse error messages, including with YYERROR_VERBOSE.
+
+ * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
+ associative).
+ Use it to check the computations.
+ Use it to check `nonassoc' is honored.
+ (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
+ `--yyerror-verbose'.
+ (_AT_CHECK_CALC): Adjust to this option.
+ (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Test also `--verbose', `--defines' and `--name-prefix'. Testing
+ the latter demonstrates a flaw in the handling of non debugging
+ parsers introduced by myself on 2000-03-16: `#define yydebug 0'
+ was used in order to simplify:
+
+ #if YYDEBUG
+ if (yydebug)
+ {
+ ...
+ }
+ #endif
+
+ into
+
+ if (yydebug)
+ {
+ ...
+ }
+
+ unfortunately this leads to a CPP conflict when
+ `--name-prefix=foo' is used since it produces `#define yydebug
+ foodebug'.
+
+ * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
+ (YYDPRINTF): New macro.
+ Spread its use.
+ * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
+ the bison options.
+ Also test `--verbose', `--defines' and `--name-prefix'.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+
+ Improve the readability of the produced parsers.
+
+ * src/bison.s1: Formatting changes.
+ Improve the comment related to the `$' mark.
+ (yydefault): Don't fall through to `yyresume': `goto' there.
+ * src/output.c (output_parser): When the `$' is met, skip the end
+ of its line.
+ New variable, `number_of_dollar_signs', to check there's exactly
+ one `$' in the parser skeleton.
+
+2000-10-02 Akim Demaille <akim@epita.fr>
+

+
+ Use the more standard files `xalloc.h' and `xmalloc.c' instead of
+ Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
+ difficult and introduced a lot of core dump. It turns out that
+ Bison used an implementation of `xmalloc' based on `calloc', and
+ at various places it does depend upon the initialization to 0. I
+ have not tried to isolate the pertinent places, and all the former
+ calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,
+ someone should address this issue.
+
+ * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.

+
+ `user_toknums' is output as a `short[]' in `output.c', while it is

+1995-10-15 Richard Stallman <rms@gnu.org>
+
+ * src/vmsgetargs.c, src/getargs.c:
+ Added -n, -k, and -raw switches.
+ (noparserflag, toknumflag, rawtoknumflag): New variables.
+
+ * src/symtab.h (SALIAS):
+ New #define for adding aliases to %token.
+ (struct bucket): Added `alias' field.

+ * src/reduce.c (reduce_grammar):
+ Revise error message.
+ (print_notices): Remove final `.' from error message.
+
+ * src/reader.c (reader_output_yylsp):
+ New function.
+ (readgram): Use `#if 0' around code that accepted %command
+ inside grammar rules: The documentation doesn't allow it,
+ and it will fail since the %command processors scan for the next %.
+ (parse_token_decl): Extended the %token
+ declaration to allow a multi-character symbol as an alias.
+ (parse_thong_decl): New function.
+ (read_declarations): Added %thong declarations.
+ (read_declarations): Handle NOOP to deal with allowing
+ % declarations as another means to specify the flags.
+ (readgram): Allow %prec prior to semantics embedded in a rule.
+ (skip_to_char, read_declarations, copy_definition)
+ (parse_token_decl, parse_start_decl, parse_type_decl)
+ (parse_assoc_decl, parse_union_decl, parse_expect_decl)
+ (get_type_name, copy_guard, copy_action, readgram)
+ (get_type, packsymbols): Revised most error messages.
+ Changed `fatal' to `warnxxx' to avoid aborting for error.
+ Revised and use multiple warnxxx functions to avoid using VARARGS1.
+ (read_declarations): Improve the error message for
+ an invalid character. Do not abort.
+ (read_declarations, copy_guard, copy_action): Use
+ printable_version to avoid unprintable characters in printed output.
+ (parse_expect_decl): Error if argument to %expect exceeds 10 digits.
+ (parse_token_decl, parse_assoc_decl, parse_type_decl, get_type):
+ Allow the type of a non-terminal can be given
+ more than once, as long as all specifications give the same type.
+
+ * src/output.c:
+ (output_headers, output_trailers, output, output_gram)
+ (output_rule_data): Implement noparserflag variable.
+ Implement toknumflag variable.
+ (output): Call reader_output_yylsp to output LTYPESTR.
+
+ * src/main.c (main):

+
+ * src/lex.h:
+ Added THONG and NOOP for alias processing.
+ Added SETOPT for the new code that allows setting options with %flags.
+
+ * src/lex.c:
+ Include getopt.h. Add some extern decls.
+ (safegetc): New function to deal with EOF gracefully.
+ (literalchar); new function to deal with reading \ escapes.
+ (lex): Use literalchar.
+ (lex): Implemented "..." tokens.
+ (literalchar, lex, parse_percent_token): Made tokenbuffer
+ always contain the token. This includes growing the token
+ buffer while reading an integer.
+ (parse_percent_token): Replaced if-else statement with percent_table.
+ (parse_percent_token): Added % declarations as another
+ way to specify the flags -n, -l, and -r. Also added hooks for
+ -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
+ major changes to files.c.
+ (lex) Retain in the incoming stream a character following
+ an incorrect '/'.
+ (skip_white_space, lex): Revised most error messages
+ and changed fatal to warn to avoid aborting.
+ (percent_table): Added %thong declarations.
+
+ * src/gram.h: Comment changes.
+
+ * src/files.c (openfiles, open_extra_files, done):
+ Add faction flag
+ and actfile file. Handle noparserflag. Both for -n switch.
+

-
-1988-05-26 Richard Stallman <rms@frosted-flakes.ai.mit.edu>
-
- * src/allocate.c (mallocate): New name for `allocate' (which loses
