+2005-07-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix problems reported by twlevo@xs4all.nl.
+ * 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.

+ and Texinfo syntax a bit, to try to make it clearer.

+
+2005-07-12 Bruno Haible <bruno@clisp.org>

+
+ * 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.
+ $($(calc_sources_generated)): Remove unnecessary test for existence
+ of target. (This had a shell syntax error anyway; a stray "x".)
+ (calc_extracted): List $(srcdir)/calc++-parser.yy, not
+ calc++-parser.yy.

+ implied by the other modules.

+
+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.
+

+
+ Extract calc++ from the documentation.
+ * doc/bison.texinfo (Calc++): Add the extraction marks.
+ * examples/extexi: New, from the aborted GNU Programming 2E.
+ Separate the different paragraph of a file with empty lines.
+ * examples/Makefile: Use it to extract the whole calc++ example.
+
+2005-06-24 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (C++ Parser Interface): Use defcv to define
+ class typedefs.
+
+2005-06-22 Akim Demaille <akim@epita.fr>
+

+ * examples/calc++/calc++-parser.yy,
+ * examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc,
+ * examples/calc++/compile, examples/calc++/test: New.
+
+2005-06-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (malloc, free) [defined __cplusplus]: Wrap inside
+ extern "C" {}. This fixes a problem reported by Paul Hilfinger,
+ which stems from the 2005-05-27 patch.
+
+2005-06-06 Paul Hilfinger <hilfingr@tully.CS.Berkeley.EDU>
+
+ * data/glr.c: Modify treatment of unused parameters to permit use
+ of g++ (which doesn't allow __attribute__ ((unused)) for parameters).
+
+2005-05-30 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix infringement on user name space reported by Janos Zoltan Szabo.
+ * data/yacc.c (yyparse): strlen -> yystrlen.
+
+2005-05-30 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (_): New.
+ Translate the various messages.
+
+2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix infringement on user name space reported by Bruno Haible.
+ * 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
+ the user name space.
+
+2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix BeOS, FreeBSD, MacOS porting problems reported by Bruno Haible.
+ * lib/bitset.c (bitset_print): Don't assume size_t can be printed
+ with %d format.
+ * lib/ebitset.c (min, max): Undef before defining.
+ * lib/vbitset.c (min, max): Likewise.
+ * lib/subpipe.c (create_subpipe): Save local variables in case

+ error message syntax used by gcc-4.0.
+
+2005-05-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention m4 1.4.3. Remove obsolete advice about
+ Sun Forte Developer 6 update 2, VMS, and MS-DOS.
+
+ * bootstrap: Remove workaround for problem I encountered with
+ gettext 0.14.1; it seems to be fixed now.
+
+2005-05-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Version 2.0a.
+
+ * src/files.c: Include "stdio-safer.h"; this fixes a typo in
+ the previous change.
+
+ Various maintainer cleanups.
+ * .cvsignore: Add a.exe, a.out, b.out,, conf[0-9]*, confdefs*,
+ conftest*, for benefit of CVS commands run at the same time as
+ "configure". Add build-aux, since "bootstrap" now creates it and
+ its subfiles.
+ * Makefile.cfg (move_if_change): Remove.
+ * Makefile.maint: Remove the update stuff; we now use "bootstrap".
+ (ftp-gnu, www-gnu, move_if_change, local_updates, update):
+ (po_repo, do-po-update, po-update, wget_files, get-targets):
+ (config.guess-url_prefix, config.sub-url_prefix):

+ this is now the recommended name.
+ * config/.cvsignore: Remove config.guess, config.rpath, config.sub,
+ depcomp, install-sh, mdate-sh, missing, mkinstalldirs, texinfo.tex,
+ ylwrap. These files now go into build-aux.
+ * config/move-if-change: Remove.
+ * config/prev-version.txt: Bump from 1.75 to 2.0.
+
+ * bootstrap: Add stdio-safer, unistd-safer modules.
+ Remove m4/glibc2.m4 (introduced by latest gnulib, but
+ we don't need it).
+ * lib/.cvsignore: Add dup-safer.c, fd-safer.c,
+ fopen-safer.c, stdio-safer.h, unistd-safer.h.
+ * lib/subpipe.c: Include "unistd-safer.h".
+ (create_subpipe): Make sure all the newly-created
+ file descriptors are > 2, so that diagnostics don't
+ get sent down them (which might cause Bison to hang, in theory).
+ * m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
+ * src/files.c (xfopen): Use fopen_safer, not fopen.
+
+ * data/lalr1.cc (yy::]b4_parser_class_name[::parse): Port
+ yesterday's yacc.c fix.
+
+2005-05-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c, data/lalr1.cc: Update copyright date.
+
+ Fix a destructor bug reported by Wolfgang Spraul in
+ <http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
+ * data/yacc.c (yyabortlab): Don't call destructor, and
+ don't set yychar to EMPTY.
+ (yyoverflowlab): Don't call destructor.
+ (yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
+ * tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
+ since we no longer output the message "discarding lookahead token
+ end of input ()".
+
2005-05-20 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
* data/glr.c (YY_SYMBOL_PRINT): Don't print newline at end to
