* src/files.c, src/files.h (pre_prologue_obstack,
post_prologue_obstack): Remove.
* src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header

(output): Remove freeing of pre_prologue_obstack and

* src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
than prologue_augment for prologue parsing so you don't need prologue
obstacks.
(grammar_declaration): Use `braceless' instead of "{...}" so that

post_prologue_obstack.
* src/reader.h (prologue_augment): Remove.

%code qualifiers, provide macros that retrieve the associated values
and build these lists automatically. Thus Bison will now warn when a
variable or qualifier is not used by the skeleton in the current
invocation regardless of whether it might sometimes be used by that
skeleton in other invocations. Also, move all %define value macros to
the b4_percent_define_ namespace, and remove the %define "NAME" {CODE}
form, which is replaced by %code.
* data/bison.m4 (b4_check_for_unrecognized_names): Rename to...
(b4_check_user_names): ... this, and change the series of valid name
arguments to a single list argument for names used in the skeleton
similar to the existing list argument for names used in the grammar.
Warn instead of complaining.
(b4_get_percent_define, b4_get_percent_code): New to retrieve %define
values and %code code, to format %code code properly, and to build
lists of all %define variables and %code qualifiers used in the
skeleton: b4_skeleton_percent_define_variables and
b4_skeleton_percent_code_qualifiers.
(b4_check_percent_define_variables, b4_check_percent_code_qualifiers):
Remove, and...
(m4_wrap): ... m4_wrap b4_check_user_names invocations instead so that
the skeleton names lists can finish building first. In place of
b4_used_percent_define_variables and b4_used_percent_code_qualifiers,
expect the lists b4_user_percent_define_variables and
b4_user_percent_code_qualifiers.
* data/c++.m4: Where setting default values for b4_parser_class_name,
b4_location_type, b4_filename_type, b4_namespace, and
b4_define_location_comparison, update their names to the
b4_percent_define_ namespace.
* data/glr.c: Don't use b4_check_percent_define_variables and
b4_check_percent_code_qualifiers. Use b4_get_percent_code.
* data/glr.cc, data/lalr1.cc: Likewise, and use b4_get_percent_define.
(b4_parser_class_name, b4_namespace): Define these using
b4_get_percent_define for parser_class_name and namespace. Normally
this would be a bad idea since there might be cases when the variables
aren't used, but these variables are too pervasive in these skeletons
for that to be a problem.
* data/location.cc: Use b4_get_percent_define.
* data/push.c: Don't use b4_check_percent_define_variables and
b4_check_percent_code_qualifiers. Use b4_get_percent_code.
* data/yacc.c: Likewise, and don't call m4_exit in
b4_use_push_for_pull_if or m4_wrap code will never execute.
* src/muscle_tab.c, src/muscle_tab.h (muscle_grow_used_name_list):
Rename to...
(muscle_grow_user_name_list): ... this for consistency with the
terminology used in bison.m4.
* src/parse-gram.y (prologue_declaration): Prepend "percent_define_" to
%define variable names, and rename muscle used_percent_define_variables
to user_percent_define_variables.
(grammar_declaration): Rename muscle used_percent_code_qualifiers to
user_percent_code_qualifiers.
(content): Remove.
(content.opt): Replace content RHS with STRING RHS so %define "NAME"
{CODE} form is no longer accepted.
* tests/input.at (Reject bad %code qualifiers): Rename to...
(Reject unused %code qualifiers): ... this, and update test output.
(%define error): Update test output.
unrecognized %code qualifiers. Check for redefined %define variables.
* data/bison.m4 (b4_check_for_unrecognized_names): New macro that
generalizes...
(b4_check_percent_code_qualifiers): ... this, which now wraps it.
(b4_check_percent_define_variables): New, also wraps it.
* data/glr.c: Unless glr.cc is wrapping glr.c, declare no valid %define
variables using b4_check_percent_define_variables.
* data/glr.cc, data/lalr1.cc: Declare the valid %define variables as
all those exercised in the test suite and all those listed in the
`Default values' section of c++.m4. Are there others?
* data/push.c, data/yacc.c: Declare no valid %define variables.
* src/muscle_tab.c, src/muscle_tab.h (muscle_find_const): New function,
similar to muscle_find, but it works even when the muscle stores a
const value.
(muscle_grow_used_name_list): New function for constructing the used
name list muscles that b4_check_for_unrecognized_names requires.
* src/parse-gram.y (prologue_declaration): Warn if a variable is
%define'd more than once. Define the b4_used_percent_define_variables
muscle with muscle_grow_used_name_list.
(grammar_declaration): Abbreviate %code code with
muscle_grow_used_name_list.
* tests/input.at (%define errors): New.
skeletons, and use this for %code qualifier complaints.
* data/bison.m4 (b4_error_at): New, invoked by...
(b4_warn_at, b4_complain_at, b4_fatal_at): ... these new macros to wrap
the skeleton scanner's new @warn_at(...@), @complain_at(...@), and
@fatal_at(...@) directives.
(b4_check_percent_code_qualifiers): Rewrite to expect locations for
qualifiers in b4_used_percent_code_qualifiers and to use
b4_complain_at.
* src/location.c, src/location.h (boundary_set_from_string): New global
function.
* src/muscle_tab.c, src/muscle_tab.h (muscle_boundary_grow): New global
function.
* src/parse-gram.y (grammar_declaration): Add locations for qualifiers
to b4_used_percent_code_qualifiers.
* src/scan-skel.l (fail_for_at_directive_too_few_args): New static
function.
(AT_DIRECTIVE_ARGC_MAX): Increase for boundary arguments.
(lineno): Rename to...
(out_lineno): ... this so I don't misunderstand it again.
(SC_AT_DIRECTIVE_SKIP_WS): Don't increment out_lineno for newlines
here; these newlines are in the input but not the output file.
(SC_AT_DIRECTIVE_ARG): Likewise. Extract directive execution to...
(at_directive_perform): ... this new static function, and add handling
of new @warn_at(...@), @complain_at(...@), and @fatal_at(...@)
directives.
* tests/input.at (Reject bad %code qualifiers): Update test output with
locations and extend.
* tests/output.at (Output file name: [, Output file name: ]): Remove
bogus comment about these tests failing.
`bison ', use m4_index instead of m4_substr since chopping up a string
containing M4-special characters causes problems here.
Fix a couple of bugs related to special characters in user-specified
file names, and make it easier for skeletons to compute output file
names with the same file name prefix as Bison-computed output file
names.
* data/glr.cc, data/push.c, data/yacc.c: In @output, use
b4_parser_file_name and b4_spec_defines_file instead of
@output_parser_name@ and @output_header_name@, which are now redundant.
* data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
b4_parser_file_name, b4_spec_defines_file, and the new
@basename(FILENAME@) instead of @output_parser_name@ and
@output_header_name@, which inappropriately escaped the file names as
C string literals.
* src/files.c (all_but_ext): Remove static qualifier.
(compute_output_file_names): Move `free (all_but_ext)' to...
(output_file_names_free): ... here since all_but_ext is needed later.
* src/files.h (all_but_ext): Extern.
* src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
exactly what MUSCLE_INSERT_STRING used to do.
(MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
characters are escaped properly.
* src/output.c (prepare): Define muscle file_name_all_but_ext as
all_but_ext.
For pkgdatadir muscle, maintain previous functionality by using
MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
is that b4_pkgdatadir is used inside m4_include in the skeletons, so
digraphs would never be expanded. Hopefully no one has M4-special
characters in his Bison installation path.
* src/scan-skel.l: Don't parse @output_header_name@ and
@output_parser_name@ anymore since they're now redundant.
In @output, use decode_at_digraphs.
Parse a new @basename command that invokes last_component.
(decode_at_digraphs): New.
(BASE_QPUTS): Remove unused.
* tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): New macro.
(Output file name): New tests.
* src/files.h (parser_file_name, spec_verbose_file, spec_graph_file):
(spec_defines_file, dir_prefix): Now char *, not const char *,
since they are freed.
* src/files.c: Likewise.
(all_but_ext, all_but_tab_ext, src_extension, header_extension):
Likewise.
(tr): Now operates in-place. All uses changed.
(compute_exts_from_gf, compute_exts_from_src): Don't leak temporary
values.
(compute_file_name_parts, compute_output_file_names): Don't store
read-only data in variables that will be freed.
(compute_output_file_names): Free all_but_ext, all_but_tab_ext,
src_extension, and header_extension.
(output_file_names_free): New public function to free
spec_verbose_file, spec_graph_file, spec_defines_file,
parser_file_name, and dir_prefix.
* src/getargs.c (getargs): Don't store read-only data in variables that
will be freed.
* src/main.c (main): Invoke output_file_names_free, code_scanner_free
(which previously existed but was unused), and quotearg_free.
* src/muscle_tab.h (muscle_insert): value arg is now a `char const *'.
* src/muscle_tab.c: Likewise.
(muscle_entry): Make the value char const *,
and add a new storage member that is char * and can be freed.
(muscle_entry_free): New private function.
(muscle_init): Use it instead of free.
(muscle_insert, muscle_grow): Update and use new storage member.
(muscle_code_grow): Free the string passed to muscle_grow
since it's not needed anymore.
* src/parse-gram.y (%union): Make `chars' member a `char const *', and
add a new `char *code' member.
("{...}"): Declare semantic type as code.
* src/scan-code.h (translate_rule_action):
(translate_symbol_action, translate_code, translate_action): Return
`char const *' rather than `char *' since external code should not free
these strings.
* src/scan-code.l: Likewise.
* src/scan-gram.l (<SC_BRACED_CODE>): Use val->code for BRACED_CODE,
which is "{...}" in the parser.
* tests/Makefile.am (maintainer-check-valgrind): Set
VALGRIND_OPTS='--leak-check=full --show-reacheable=yes' before invoking
Valgrind.
* tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
complain.
* tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
expecting a non-zero exit status sets --leak-check=summary and
--show-reachable=no for Valgrind. Bison unabashedly leaks memory in
this case, and we don't want to hear about it.
* data/c.m4 (b4_copyright, b4_epilogue, b4_location_initial_column,
b4_location_initial_line, p4_parse_param, b4_ints_in, b4_flag_if,
b4_define_flag_if and uses, b4_basename, b4_syncline, b4_user_code,
b4_define_user_cde and uses): Remove.
(b4_comment, b4_prefix, b4_sync_start): New.
* data/bison.m4: New file, with most of the content removed from c.m4.
* src/muscle_tab.h: Use "do {...} while(0)" throughout.
* src/output.c (output_skeleton): Pass bison.m4.
(prepare): Pass glr_flag and nondeterministic_flag. Pass prefix
only if specified.
least 1.4.7 and 1.4.4) by putting a #line between `typedef union
YYSTYPE' and `{'.
* src/muscle_tab.h (muscle_grow): Replace the header comments with
those from muscle_tab.c since the old ones are misleading.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space. All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).
* etc/clcommit: Remove. We weren't using it, and it failed
"make maintainer-distcheck".
* Makefile.maint: Merge from coreutils.
(CVS_LIST, CVS_LIST_EXCEPT): New macros.
(syntax-check-rules): Change list of rules as described below.

* data/m4sugar/m4sugar.m4: Sync from Autoconf, except that
we comment out the Autoconf version number.
* doc/bison.texinfo (Calc++ Scanner): Don't use atoi, as

* src/getargs.h: Redo comments to pacify "make maintainer-distcheck".
* src/main.c (main): Cast bindtextdomain and textdomain calls to
void, to avoid warning when NLS is disabled.

Indent calls to "error" to pacify "make maintainer-distcheck".

Indent calls to "error" to pacify "make maintainer-distcheck".

affects Bison's own parser. Therefore we need (i) to extend Bison

with...
* src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this.

* data/yacc.c (yyparse): Use b4_initial_action.

* 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.
(output_obstack): Remove it, and all its dependencies, as it is no
longer needed.
* src/reader.c (epilogue_set): Build the epilogue in the
muscle_obstack.
* src/output.h, src/output.c (muscle_obstack): Move to...
* src/muscle_tab.h, src/muscle_tab.h: here.
(muscle_init): Initialize muscle_obstack.
(muscle_free): New.
* src/main.c (main): Call it.
* src/output.c (output_table_data): Return the longest number.
(prepare_tokens): Output `token_number_max').
* data/bison.simple, data/bison.c++ (b4_sint_type, b4_uint_type):
New.
Use them to define yy_token_number_type/TokenNumberType.
Use this type for yytranslate.
* tests/torture.at (Big triangle): Push the limit from 124 to
253.
* tests/regression.at (Web2c Actions): Adjust.
* lib/readpipe.c: New, from wdiff.
* src/Makefile.am (DEFS): Define PKGDATADIR, not BISON_SIMPLE and
BISON_HAIRY.
* src/system.h (BISON_HAIRY, BISON_SIMPLE): Remove the DOS and VMS
specific values. Now it is m4 that performs the lookup.
* src/parse-skel.y: Remove.
* src/muscle_tab.c, src/muscle_tab.h (muscles_m4_output): New.
* src/output.c (actions_output, guards_output)
(token_definitions_output): No longer keeps track of the output
line number, hence remove the second argument.
(guards_output): Check against the guard member of a rule, not the
action member.
Adjust callers.
(output_skeleton): Don't look for the skeleton location, let m4 do
that.
Create `/tmp/muscles.m4'. This is temporary, a proper temporary
file will be used.
Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
(prepare): Given that for the time being changesyntax is not
usable in M4, rename the muscles using `-' to `_'.
Define `defines_flag', `output_parser_name' and `output_header_name'.
* src/output.h (actions_output, guards_output)
(token_definitions_output): Adjust prototypes.
* src/scan-skel.l: Instead of scanning the skeletons, it now
processes the output of m4: `__oline__' and `#output'.
* data/bison.simple: Adjust to be used by M4(sugar).
* tests/Makefile.am: Use check_SCRIPTS to make sure `bison' is up
to date.
* tests/bison.in: Use the secrete envvar `BISON_PKGDATADIR'
instead of the dead `BISON_SIMPLE' and `BISON_HAIRY'.
* data/m4sugar/m4sugar.m4, data/m4sugar/version.m4: New,
shamelessly stolen from CVS Autoconf.
(MUSCLE_INSERT_PREFIX): ...to there.
* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): Move from here...
* src/bison.hairy: Add a section directive. Put braces around muscle
names. This parser skeleton is still broken, but Bison should not
choke on a bad muscle 'syntax'.
* src/bison.simple: Add a section directive. Put braces around muscle
names.
* src/files.h (strsuffix, stringappend): Add declarations.
(tab_extension): Add declaration.
(short_base_name): Add declaration.
* src/files.c (strsuffix, stringappend): No longer static. These
functions are used in the skeleton parser.
(tab_extension): New.
(compute_base_names): Use the computations done in this function
to guess if the generated parsers should have '.tab' in their
names.
(short_base_name): No longer static.
* src/output.c (output_skeleton): New.
(output): Disable call to output_master_parser, and give a try to
a new skeleton handling system.
(guards_output, actions_output): No longer static.
(token_definitions_output, get_lines_number): No longer static.
* configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
parse-skel.y.
* src/parse-skel.y: New file.
* src/scan-skel.l: New file.
