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

+ * 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>
+

+ 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.
+ $($(calc_sources_generated)): Remove unnecessary test for existence

+
+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.

+
+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.

+
+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/vbitset.c (min, max): Likewise.
+ * lib/subpipe.c (create_subpipe): Save local variables in case

+
+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):

+ 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>

+ 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
+ fix a small glitch in debugging output.
+ (yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
+ after YY_SYMBOL_PRINT where needed.

+ From Marcus Holland-Moritz.
+ * data/yacc.c (yyerrlab): Move the code that destroys the stack
+ from here....
+ (yyreturn): to here. That way, destructors are called properly
+ even if the stack overflows, or the user calls YYACCEPT or
+ YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
+ (yyoverflowlab): Destroy the lookahead.
+
+2005-04-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): Add more-descriptive comment.
+
+2005-04-17 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Bison-generated C parsers no longer quote literal strings
+ associated with tokens.
+ * src/output.c (prepare_symbols): Don't escape strings,
+ since users don't want to see C escapes.
+ * tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
+ in diagnostics.
+ * tests/input.at (Torturing the Scanner): Likewise.

+
+ * tests/torture.at (AT_INCREASE_DATA_SIZE): Skip the test if

+ This works around an HP-UX 11.00 glitch reported by Andrew Benham.
+
+2005-04-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y: Include quotearg.h.
+ (string_as_id): Quote $1 before using it as a key, since the
+ lexer no longer quotes it for us.
+ (string_content): Don't strip quotes, since lexer no longer
+ quotes it for us.
+ * src/scan-gram.l: Include quotearg.h.
+ ("\""): Omit quote.
+ ("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
+ a key, since the rest of the lexer doesn't quote it.
+ * src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
+ * tests/regression.at (Token definitions): Check for backslashes
+ in token strings.
+
+ * data/yacc.c (YYSTACK_ALLOC_MAXIMUM): New macro.
+ (YYSIZE_T): Define to unsigned long int when using an older compiler.
+ (yyparse): Revamp code to generate long syntax error message, to
+ make it easier to translate, and to avoid problems with arithmetic
+ overflow. Change "virtual memory" to "memory" in diagnostic, since
+ we don't know whether the memory is virtual.
+
+2005-04-13 Paul Eggert <eggert@cs.ucla.edu>

+
+2005-04-12 Paul Eggert <eggert@cs.ucla.edu>
+

+ (symbol_check_alias_consistency): Don't call symbol_type_set
+ if the type name is already correct.
+ * tests/input.at (Typed symbol aliases): New test, from Tim Van Holder.
+
+2005-03-25 Paul Eggert <eggert@cs.ucla.edu>

+
+2005-03-21 Paul Eggert <eggert@cs.ucla.edu>

+ (_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

+
+ 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

+ Adjust uses to make sure the code is triggered on empty
+ reductions.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the

+2004-09-27 Paul Eggert <eggert@cs.ucla.edu>

+
+2004-09-20 Akim Demaille <akim@epita.fr>

+ * 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

+ 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.
+
+2004-09-06 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Adjust the indentation of the labels.

+ 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

+ hand".
+
+2004-09-03 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was
+ invoked, yydestruct the lookahead.
+ * tests/calc.at (Calculator $1): Update the expected lengths of

+ * doc/bison.texinfo (Destructor Decl): Some rewording.
+ Define "discarded" symbols.
+
+2004-09-02 Akim Demaille <akim@epita.fr>

+ two.
+ Use it instead of direct symprint_ calls.
+ (yybackup): Tweak the "Now at end of input" case to match yacc.c's
+ one.
+
+2004-09-02 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (b4_yysymprint_generate): New.
+ (symprint_): New member function, defined when YYDEBUG.
+ Use it consistently instead of token/nterm debugging output by
+ hand.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
+ %printer calls to use cdebug_ when using lalr1.cc.
+
+2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
+
+ * data/glr.c: Guard the declarations of yypstack and yypdumpstack
+ with #ifdef YYDEBUG.
+
+2004-08-26 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Implementing Loops): Rename as...
+ (Implementing Gotos/Loops): this.
+
+2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to latest gnulib.
+ * bootstrap (gnulib_modules): Add xalloc-die.
+ Set LC_ALL=C so that file names sort consistently.
+ Prefer the gnulib copies of gettext.m4, glibc21.m4,

+
+2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>

+
+2004-06-21 Paul Eggert <eggert@cs.ucla.edu>

+ 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.

+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim

+
+2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention GNU m4 1.4 bugs and Akim's patched version.

+ 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

+
+ * 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

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
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.
