+2002-11-24  Paul Eggert  <eggert@twinsun.com>
+
+       Version 1.75c.
+
+       * tests/actions.at (Actions after errors): Use an output format
+       more similar to that of the Printers and Destructors test.
+       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>
+
+       * lib/quotearg.c, lib/quotearg.h: Sync with gnulib.

+
+2002-11-20  Paul Eggert  <eggert@twinsun.com>
+       
+       Avoid use of <assert.h>, as the GNU Coding Standards hint that one
+       should use `if (! x) abort ();' rather than `assert (x);', and
+       anyway it's one less thing to worry about configuring.
+
+       * data/glr.c, lib/hash.c, src/system.h: Do not include <assert.h>.
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Likewise,
+       and replace all instances of assert with abort.

+       yyresolveAction, yyprocessOneStack): Use abort rather than assert.

+       state_reduction_find): Likewise.
+       * src/symtab.c (symbol_user_token_number_set, symbol_make_alias,
+       symbol_pack): Likewise.
+       * src/tables.c (conflict_row, pack_vector): Likewise.
+       * src/vcg.c (get_color_str, get_textmode_str, get_shape_str,
+       get_layoutalgorithm_str, get_decision_str, get_orientation_str,
+       get_node_alignement_str, get_arrow_mode_str, get_crossing_type_str,
+       get_view_str, get_linestyle_str, get_arrowstyle_str): Likewise.
+
+       * lib/argmatch.h (ARRAY_CARDINALITY): Do not bother to #undef.

+       rather than assert.
+       * src/tables.c (tables_generate): Likewise.
+
+       * src/struniq.c (struniq_assert): Now returns void, and aborts
+       if the assertion is false.
+       (struniq_assert_p): Remove.
+       * src/struniq.h: Likewise.
+
+2002-11-18  Paul Eggert  <eggert@twinsun.com>
+
+       * data/glr.c (yygetLRActions): Replace `yyindex' with
+       `yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.
+       This fixes the regression with Sun ONE Studio 7 cc that I reported in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.

+
+       * data/glr.c (YYDPRINTF, YYDSYMPRINT, YYDSYMPRINTF) [!YYDEBUG]: Do
+       not define to {}, since this breaks the common use of `YYDPRINTF
+       ((...));' if a single statement is desired (e.g. before `else').
+       Work around GCC warnings by surrounding corresponding calls with
+       {} if needed.
+       (yyhasResolvedValue): Remove unused function.
+       (yymergeOptionSets, yyresolvStack): Use `continue;' for empty

+       All uses changed.

+
+       Augment the similarity between GLR and LALR traces.
+
+       * data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
+       (YY_REDUCE_PRINT): New.
+       (yyparse): Use them.
+       * data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
+       YYDPRINT here.
+       (yyglrReduce, yyrecoverParseError, yyparse): Don't report the
+       state reached after the reduction/recovery, since...
+       (yyparse, yyprocessOneStack): Report the state we are entering in.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+       * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
+       Add support for --trace=skeleton.
+       * src/scan-skel.l: %option debug.
+       Scan strings of non-@ or \n instead of character by character.
+       (scan_skel): Handle trace_skeleton.
+       (QPUTS): New.
+       (@output_parser_name@, @output_header_name@): ``Restore'' their
+       support (used to be M4 macros).
+       * data/yacc.c: Quote larger chunks, a la glr.c.
+       * data/lalr1.cc: Likewise.
+       The header guards are no longer available, so use some other
+       string than `YYLSP_NEEDED'.
+
+2002-11-16  Akim Demaille  <akim@epita.fr>
+
+       Make the ``Printers and Destructors'' test more verbose, taking
+       `yacc.c''s behavior as (possibly wrong) reference.
+
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
+       instead of fprint on stdout.
+       Set and report the last_line of the symbols.
+       Consistently display values and locations.
+
+2002-11-16  Paul Eggert  <eggert@twinsun.com>

+       src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
+       tests/action.at, tests/calc.at, tests/conflicts.at,
+       tests/cxx-type.at, tests/regression.at:
+       "parse error" -> "syntax error" for POSIX compatibility.
+       "parsing stack overflow..." -> "parser stack overflow" so
+       that code matches Bison documentation.
+
+2002-11-15  Akim Demaille  <akim@epita.fr>
+
+       * src/parse-gram.y (declaration): Have %parse-param and %lex-param
+       take two BRACED_CODE, not two string_content.
+       Free the scanner's obstack when we are done.
+       (code_content): New.
+       * tests/calc.at: Adjust.
+       * doc/bison.texinfo: Adjust.

+
+       * m4/prereq.m4: Removed the commented jm_PREREQ_HASH

+
+       * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
+       "$CC -E foo.h" is allowed, as this doesn't work with the Portland
+       Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
+       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
+       we'll run into compiler bugs.  Bring back solitary \ inside
+       comment, but add a closing comment to work around HP C bug.  Don't
+       test backslash-newline in C character constant.  This should fix
+       the input.at bug reported by Nelson H. F. Beebe in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.

+
+       * tests/synclines.at (AT_SYNCLINES_COMPILE): Ignore the exit
+       status of the compiler.
+       Calling `exit 1' is no longer needed.
+       Reported by Nelson H. F. Beebe.

+

+       grammars that are to be compiled.

+
+2002-11-14  Akim Demaille  <akim@epita.fr>
+
+       * doc/bison.texinfo: Various formatting changes (alignments in
+       samples, additional @group/@end group, GCS in samples.
+       Use @deffn instead of simple @table to define the directives,
+       macros, variables etc.
+
+2002-11-13  Paul Eggert  <eggert@twinsun.com>
+
+       Fix some bugs reported by Albert Chin-A-Young in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001881.html>.
+
+       * tests/input.at (Torturing the Scanner): Don't invoke "cc a.c b.c
+       -o c"; the HP C compiler chatters during compilation.
+       Instead, invoke "cc -c a.c -o a.o; cc -c b.c -o b.o; cc a.o b.o -o c".
+       * tests/headers.at (export YYLTYPE): Likewise.
+
+       * tests/input.at (Torturing the Scanner): Remove lines containing
+       solitary backslashes, as they tickle a bug in the HP C compiler.
+
+       * tests/glr-regr1.at (Badly Collapsed GLR States): Avoid //
+       comments, since they're not portable.  Use GNU coding style.

+
+       Version 1.75b.
+
+       * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
+       (yyglrReduce): Return yyok, not 0.
+       This should avoid the enumerated-type warnings reported
+       by Nelson H.F. Beebe in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.

+       to avoid shadowing warnings by GCC.
+
+       * data/glr.c (inline): Remove #define.  It's the user's
+       responsibility to #define it away, just like 'const'.
+       This fixes one of the bugs reported by Nelson H.F. Beebe in

+
+       * Makefile.maint (po-check): Scan .l and .y files instead of the
+       .c and the .h files that they generate.  This fixes the bug
+       reported by Tim Van Holder in:
+       <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
+       Look for N_ as well as for _.  Try to avoid matching #define for
+       N_ and _.
+       * po/POTFILES.in: Remove src/parse-gram.c, src/scan-gram.c,
+       src/system.h.  Add src/parse-gram.y, src/scan-gram.l.
+       * src/scan-gram.l: Revamp regular expressions so that " and '
+       do not confuse xgettext.
+
+       * src/struniq.h (struniq_new): Do not declare the return type
+       to be 'const'; this violates the C standard.

+2002-11-12  Albert Chin-A-Young <china@thewrittenword.com>
+
+       * src/Makefile.am (LDADD): Link $(LIBINTL) last to avoid the

+       not yyvalue.
+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * tests/actions.at (AT_CHECK_PRINTER_AND_DESTRUCTOR): New.

+
+2002-11-12  Akim Demaille  <akim@epita.fr>
+
+       * tests/regression.at (input.y): s/YYEOF/MYEOF/, as the skeleton

+       * data/yacc.c: Rename yychar1 as yytoken, as in glr.c.
+       Don't work on yychar (i.e., do set it to YYEMPTY, don't match

+2002-11-11  Paul Eggert  <eggert@twinsun.com>
+
+       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://mail.gnu.org/pipermail/bison-patches/2002-November/001329.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,
+       b4_output_header_suffix, b4_output_header_name, b4_header_guard):
+       Remove, since they couldn't handle arbitrary characters in file
+       names.
+       * data/lalr1.cc: Likewise.
+       * data/yacc.c: Likewise.
+
+       * src/files.c (output_infix): Remove; all uses removed.
+       * src/files.h: Likewise.
+
+       * data/glr.c: Remove use of "#ifdef b4_header_guard", since it
+       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
+       strings now.
+       (muscle_init): Quote filename as a C string.
+       * src/muscle_tab.h (MUSCLE_GROW_STRING_PAIR): Remove; unused.
+       (MUSCLE_OBSTACK_SGROW, MUSCLE_INSERT_C_STRING): New macros.
+       * src/output.c (escaped_file_name_output): New function.
+       (prepare_symbols): Quote tokens for M4.
+       (prepare): Don't insert output_infix, output_prefix,
+       output_parser_name, output_header_name; this is now down by scan-skel.
+       Insert skeleton as a C string.
+
+       * src/output.c (user_actions_output, symbol_destructors_output,
+       symbol_printers_output): Quote filenames for C and M4.
+       * src/reader.c (prologue_augment, epilogue_set): Likewise.
+
+       * src/scan-gram.l (<SC_CHARACTER>): Don't worry about any backslash
+       escapes other than \\ and \'; this simplifies the code.
+       (<SC_STRING>): Likewise, for \\ and \".
+       (<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://mail.gnu.org/pipermail/bug-bison/2002-November/001815.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.
+       (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
+       not the (never otherwised-used) CHARACTER.
+
+2002-11-07  Akim Demaille  <akim@epita.fr>
+
+       Let yyerror always receive the msg as last argument, so that
+       yyerror can be variadic.
+
+       * data/yacc.c (b4_yyerror_args): New.
+       Use it when calling yyerror.
+       * data/glr.c (b4_yyerror_args, b4_lyyerror_args): New.
+       Use it when calling yyerror.
+       * doc/bison.texinfo (Error Reporting): Adjust.
+       * tests/calc.at (_AT_DATA_CALC_Y): Adjust.
+       * tests/cxx-type.at (_AT_TEST_GLR_CALC): Adjust.
+
+2002-11-06  Akim Demaille  <akim@epita.fr>
+
+       #line should have quoted strings.
+       Ideally, this should be done by m4_quotearg.
+
+       * src/scan-skel.l: Include quotearg.h.
+       Quote __ofile__.
+       * src/output.c (symbol_printers_output)
+       (symbol_destructors_output): Quote the file name.
+
 2002-11-06  Akim Demaille  <akim@epita.fr>
 
        * tests/regression.at (Invalid inputs): Adjust to the recent
