Fileutils 4.1.5.
* configure.in: Invoke UTILS_FUNC_MKSTEMP.
* src/output.c (output_skeleton): Use mkstemp to create a real
temporary file.
Move the filling of `skeleton' and its muscle to...
(prepare): here.
(output): Move the definition of the prologue muscle to...
(prepare): here.
* src/system.h (DEFAULT_TMPDIR): New.
* 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.
* src/state.c (errs_dup): Aaaah! The failure was due to bytes
which were not properly copied! Replace
memcpy (res->errs, src->errs, src->nerrs);
with
memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
!!!
* tests/regression.at (%nonassoc and eof): Adjust to newest
Autotest: `.' is not in the PATH.
(getargs): Use it to convert DOSish file names.
* src/files.c (base_name): Rename as full_base_name to avoid
clashes with `base_name ()'.
(filename_split): New.
(compute_base_names): N-th rewrite, using filename_split.
New, stolen from the Fileutils 4.1.
* lib/Makefile.am (libbison_a_SOURCES): Adjust.
* configure.in: Check for the presence of memrchr, and of its
prototype.
convention is to fetch on entry.
* tests/torture.at (GNU Cim Grammar): Reintroduce their weird
'switch' without a following semicolon.
* tests/regression.at (braces parsing): New.
The ISO C++ standard is extremely clear about it: stderr is
considered a macro, not a regular symbol (see table 94 `Header
<cstdio> synopsis', [lib.c.files] 27.8.2 C Library files).
Therefore std:: does not apply to it. It still does with fprintf.
Also, s/cstdio.h/cstdio/.
pure parser and scanner.
* src/parse-skel.y: Request a pure parser, locations, and prefix
renaming.
(%union): Having several members with the same type does not help
type mismatches, simplify.
(YYPRINT, yyprint): New.
(yyerror): ``Rename'' (there is a #define yyerror skel_error) as...
(skel_error): this.
Handle locations.
* src/scan-skel.l: Adjust to these changes.
* src/skeleton.h (LOCATION_RESET, LOCATION_LINES, LOCATION_STEP)
(LOCATION_PRINT, skel_control_t): New.
Throw away MS-DOS crap: we don't need getpid.
* configure.in: We don't need strndup. It was even causing
problems: because Flex includes the headers *before* us,
_GNU_SOURCE is not defined by config.h, and therefore strndup was
not visible.
* lib/xstrndup.c: New.
* src/scan-skel.l: Use it.
Be sure to initialize yylval.muscle member when scanning a MUSCLE.
* src/parse-skel.y: Use %directives instead of #defines.
* src/output.c (output_parser, output_master_parser): Remove, dead
code.
* src/output.h (get_lines_number, actions_output, guards_output)
(token_definitions_output): Prototype them.
* src/parse-skel.y: Add the license notice.
Include output.h and skeleton.h.
(process_skeleton): Returns void, and takes a single parameter.
* src/scan-skel.l: Add the license notice.
Include skeleton.h.
Don't use %option yylineno: it seems that then Flex imagines
REJECT has been used, and therefore it won't reallocate its
buffers (which makes no other sense to me than a bug). It results
in warnings for `unused: yy_flex_realloc'.
to guess if the generated parsers should have '.tab' in their
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
* src/files.c (spec_name_prefix): Initialize to NULL, not to "yy".
Adjust all dependencies.
* tests/headers.at (export YYLTYPE): Strengthen this test: use
%name-prefix.
Renaming yylval but not yylloc is not consistent. Now we do.
* src/bison.simple: Prefix yylloc if used.
* doc/bison.texinfo (Decl Summary): Document that.
on command. Now possible via `symbols'. Fixes a memory leak.
* src/output.c (token_definitions_output): New.
(output_parser, header_output): Use it.
* src/reader.c (symbols_save): Remove.
* src/reader.c (readgram): Be sure to attach mid-rule actions to
the empty-rule associated to the dummy symbol, not to the host
rule.
* tests/actions.at (Mid-rule actions): New.
* src/LR0.c (new_itemsets): Don't allocate `shift_symbol' here,
since it allocates it for each state, although only one is needed.
(allocate_storage): Do it here.
and rule_table.
* src/reader.c (packsymbols): Fill this table.
Drop sprec.
* src/conflicts.c (resolve_sr_conflict): Adjust.
* src/reduce.c (reduce_grammar): Adjust: just sort symbols, a
single table.
Use symbols[i]->tag instead of tags[i].
output as expected output. The contents *seem* right to me, but I
can't pretend reading perfectly parser tables... Nonetheless, all
the other tests pass correctly, the table look OK, even though the
presence of `$axiom' is to be noted: AFAICS it is useless (but
harmless).
* src/LR0.c (final_state): Initialize to -1 so that we do compute
the reductions of the first state which was mistakenly confused
with the final state because precisely final_state was initialized
to 0.
* tests/sets.at (Nullable): Adjust: state 0 does have lookaheads,
now noticed by Bison.
* tests/regression.at (Rule Line Numbers): Adjust: state 0 does
have a reduction on $default.
when walking through ritem, even via rule->rhs.
* src/reduce.c (dump_grammar, useful_production, reduce_output)
(useful_production, useless_nonterminals): Likewise.
(reduce_grammar_tables): Likewise, plus update nritems.
* src/nullable.c (set_nullable): Likewise.
* src/lalr.c (build_relations): Likewise.
* tests/sets.at (Nullable): Adjust.
Fortunately, now, the $axiom is no longer nullable.
cases for non-GNU systems like AIX, HP-UX, SGI, Sun, and
Sparc, as they were causing more porting problems than the
(minor) performance improvement was worth.
Also, catch up with 1.31's YYSTD.
0-sentinel. See below.
Use -1 as separator, not 0.
* src/bison.simple (yyparse): Subtract 1 to the rule numbers.
Rely on -1 as separator in yyrhs, instead of 0.
* tests/calc.at (AT_CHECK_CALC): Now, the parsers no longer issue
twice `Now at end of input', therefore there are two lines less to
expect.
