+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://mail.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://mail.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://mail.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://mail.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://mail.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://mail.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):
+ Quote AC_FOREACH variable-expansions properly.
+ The 2003-01-03 obstack.h change also needs merging.
+ {end of changes requiring merging}
+
+ * lib/stdbool.h.in, m4/alloca.m4, m4/dirname.m4, m4/dos.m4,
+ m4/getopt.m4, m4/hash.m4, m4/malloc.m4, m4/memchr.m4,
+ m4/memrchr.m4, m4/obstack.m4, m4/onceonly.m4, m4/quote.m4,
+ m4/quotearg.m4, m4/realloc.m4, m4/stpcpy.m4, m4/strnlen.m4,
+ m4/strtol.m4, m4/strtoul.m4, m4/unlocked-io.m4, m4/xalloc.m4:
+ New files, imported from gnulib.
+ * m4/Makefile.am (EXTRA_DIST): Add the new m4/*.m4 files mentioned
+ above.
+
+ * lib/mbswidth.c, m4/error.m4, m4/mbrtowc.m4, m4/mbswidth.m4,
+ m4/memcmp.m4, m4/prereq.m4, m4/stdbool.m4: Update to current
+ gnulib sources.
+
+ * configure.ac (gl_DIRNAME, gl_GETOPT, gl_HASH, gl_QUOTE, gl_XALLOC):
+ Add.
+ (gl_ERROR): New, replacing jm_PREREQ_ERROR.
+ (gl_FUNC_ALLOCA): New, replacing AC_FUNC_ALLOCA.
+ (gl_FUNC_STPCPY): New, replacing AC_REPLACE_FUNCS(stpcpy).
+ (gl_FUNC_STRNLEN): New, replacing AC_FUNC_STRNLEN.
+ (gl_MBSWIDTH): New, replacing jm_PREREQ_MBSWIDTH.
+ (gl_OBSTACK): New, replacing AC_FUNC_OBSTACK.
+ (gl_QUOTEARG): New, replacing jm_PREREQ_QUOTEARG.
+ (jm_FUNC_GLIBC_UNLOCKED_IO, gl_FUNC_STPCPY, gl_FUNC_STRTOL): New.
+ (jm_FUNC_MALLOC): New, replacing AC_FUNC_MALLOC.
+ (jm_FUNC_REALLOC): New, replacing AC_FUNC_REALLOC.
+ (jm_PREREQ_ARGMATCH): Remove.
+ (AC_REPLACE_FUNCS): Remove memchr, memrchr, stpcpy, strtol, strtoul.
+ * lib/Makefile.am (libbison_a_SOURCES): Add argmatch.c, argmatch.h.
+
+ * 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>
+
+ * ro.po: New.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Table of Symbols): Reactivate the
+ documentation for %lex-param, and %parse-param.
+
+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...
+ * tests/local.at: here.
+ (AT_COMPILE_CXX): Tags the tests using it as c++.
+ 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://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
