+ 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".

+ 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

+
+ 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

+ 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.

+ * data/glr.c, data/yacc.c: Do not use apostrophes in '#' comments,
+ as they confuse xgettext, which tries to parse them as C character

+ * data/yacc.c (yy_lac): Don't use printf %d format on *yyesp, as

+
+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.
+

+ (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.
+ (%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.
+
+2010-11-21 Joel E. Denny <joeldenny@joeldenny.org>
+
+ 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: adjust prior fixes for branch-2.5's lalr1.cc.
+ On master, there is no yychar in lalr1.cc, but there is on
+ branch-2.5, and the prior cherry-pick of "Fix handling of yychar
+ manipulation in user semantic actions" wasn't adjusted for that
+ difference.
+ * data/lalr1.cc (yy::parser::parse): Translate yychar before
+ every use of yytoken, and add comments explaining this approach.
+ * tests/conflicts.at (%error-verbose and consistent errors):
+ Extend to test yychar manipulation with lalr1.cc.
+
+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,
+ set yytoken to yyempty_ before invoking 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 (%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 (%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.
+
+2010-10-31 Joel E. Denny <joeldenny@joeldenny.org>
+
+ * ChangeLog: Correct some errors in previous entries.
+
+2010-10-17 Joel E. Denny <joeldenny@joeldenny.org>
+
+ maint: re-anchor all .gitignore entries.
+ * bootstrap: Copy from gnulib's latest for the fix to
+ automatically anchor entries it constructs.
+ * gnulib: Update to latest just so it has the same bootstrap.
+ * .gitignore, build-aux/.gitignore, doc/.gitignore:
+ * lib/.gitignore, m4/.gitignore, po/.gitignore:
+ * runtime-po/.gitignore: Re-anchor all entries.
+
+2010-10-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix portability problem on OpenBSD 4.7.
+
+ Jim Meyering reported this in
+ <http://lists.gnu.org/archive/html/bug-bison/2010-10/msg00007.html>.
+ * 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.
+ * README-hacking: Renamed from HACKING, since gnulib bootstrap now
+ uses that convention.
+

+
+ -Werror: fix for rules useless in parser after conflicts.
+ * NEWS (2.4.3): Document fix.

+ * src/gram.c (grammar_rules_useless_report): Use warn_at so that
+ -Werror is always obeyed.
+ * src/reduce.c (reduce_print): Use warn so that the "warnings

+ * tests/local.at (AT_BISON_WERROR_MSG): New macro.
+ (AT_BISON_CHECK_NO_XML): Extend to check -Werror and
+ --warnings=error when warnings appear in bison's stderr.
