arguments and output `void'.
(b4_c_function): Rename as...
(b4_c_function_def): this.
(b4_c_function_decl, b4_c_ansi_function_def)
(b4_c_ansi_function_decl): New.
Change the interpretation of the arguments: before `int, foo', now
`int foo, foo'.
* data/yacc.c (yyparse): Prototype and define thanks to these.
Adjust b4_c_function_def uses.
* data/glr.c (yyparse): Likewise, but ANSI only.
LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
Use them to have `calc.y' ready for %pure-parser.
* data/yacc.c (YYLEX): Pass a yylex return type to
b4_c_function_call.
* src/parse-gram.y: Add the definition of the %lex-param and
%parse-param tokens, plus their rules.
Drop the `_' version of %glr-parser.
Add the "," token.
* src/scan-gram.l (INITIAL): Scan them.
* src/muscle_tab.c: Comment changes.
(muscle_insert, muscle_find): Rename `pair' as `probe'.
* src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
(muscle_entry_s): The `value' member is no longer const.
Adjust all dependencies.
* src/muscle_tab.c (muscle_init): Adjust: use
MUSCLE_INSERT_STRING.
Initialize the obstack earlier.
* src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
(muscle_pair_list_grow): New.
* data/c.m4 (b4_c_function_call, b4_c_args): New.
* data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
* tests/calc.at: Use %locations, not --locations.
(AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
accordingly.
Report the traditional `Try ... --help' message when status != 0.
(usage, version): Don't take a FILE * as arg, it is pointless.
(getargs): When there is an incorrect number of arguments, make it
an error, and report it GNUlically thanks to `usage ()'.
it confused me, and I was the author! Instead, assume that people
who want to use K&R C compilers (when using these modules in GCC,
perhaps?) will run ansi2knr.
tests/cxx-type.at, tests/headers.at, tests/input.at,
tests/regression.at, tests/synclines.at, tests/torture.at:
Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
so that the tests still work even if POSIXLY_CORRECT is set.
* doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
for portability to K&R hosts. Fix typo: signed char is guaranteed
only to 127, not to 128.
* data/glr.c (yysigned_char): New type.
* data/yacc.c (yysigned_char): Likewise.
* tests/regression.at (Web2c Actions): signed char -> yysigned_char.
tables.
With the patch, GAWK compiled by GCC without -O2 passes its test
suite using a GLR parser driven by LALR tables. It fails with -O2
because `struct stat' gives two different answers on my machine:
88 (definition of an auto var) and later 96 (memset on this var).
Hence the stack is badly corrumpted. The headers inclusion is to
blame: if I move the awk.h inclusion before GLR's system header
inclusion, the two struct stat have the same size.
* src/tables.c (pack_table): Always create conflict_table.
(token_actions): Always create conflict_list.
* data/glr.c (YYFLAG): Remove, unused.
default reduction.
Reported by Charles-Henry de Boysson.
* tests/calc.at (_AT_CHECK_CALC, _AT_CHECK_CALC_ERROR): Don't
check the length of the traces when %glr.
(_AT_CHECK_CALC_ERROR): Also skip `^Stack' lines, coming from
GLR's traces.
(AT_CHECK_CALC_LALR, AT_CHECK_CALC_GLR): New.
Test GLR parsers.
* data/glr.c (YYLEFTMOST_STATE): Fix its value.
(yyltype): Remove the yy prefix from the member names.
(yytable): Complete its comment.
(yygetLRActions): Map error action number from YYTABLE from
YYTABLE_NINF to 0.
(yyisErrorAction): No longer compare YYACTION to YYPACT_NINF
(which was a bug: it should have been YYTABEL_NINF, and yet it was
not satisfying as we could compare an YYACTION computed from
YYDEFACT to YYTABLE_NINF although they are unrelated): 0 is the
only value for error actions.
(yyreportParseError): In verbose parse error messages, don't issue
`error' in the list of expected tokens.
* data/yacc.c (yyparse) <yybackup>: Rewrite the decoding of the
next action to perform to match glr.c's decoding.
(yytable): Complete its comment.
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
"nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
because the Bison parser reads the second action before reducing
the first one.
* src/scan-gram.l (rule_length): New static var.
Use it to keep track of the rule length in the scanner, since
we can't expect the parser to be in lock-step sync with the scanner.
(handle_action_dollar, handle_action_at): Use this var.
* tests/actions.at (Exotic Dollars): Test for the problem.
(yyparse): here. This undoes some of the 2002-07-25 change.
Compatibility problem reported by Ralf S. Engelschall with
OSSP cfg <http://www.ossp.org/pkg/lib/cfg/>.
the same width as int. This reapplies a hunk of the 2002-08-12 patch
<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
which was inadvertently undone by the 2002-09-30 patch.
* lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
the same width as int.
* configure.ac: Remove the old LIBOBJ tweaks.
(AC_REPLACE_FUNCS): Add strrchr and strtol.
* lib/strrchr.c: New.
* lib/strtol.c: New, from the Coreutils 4.5.1.
* m4/prereq.m4 (jm_PREREQ_ARGMATCH, jm_FUNC_ARGMATCH): New.
* lib/Makefile.am (libbison_a_SOURCES): No longer include
argmatch.c and argmatch.h, since they are AC_LIBSOURCE'd.
* lib/strcasecmp.c, lib/strncasecmp.c, lib/memcmp.c: New, from the
Coreutils 4.5.1.
