bucket.
Adjust all dependencies.
* src/reduce.c (nonterminals_reduce): Don't forget to renumber the
`number' of the buckets too.
* src/gram.h: Include `symtab.h'.
(associativity): Move to...
* src/symtab.h: here.
No longer include `gram.h'.
(ritem_longest_rhs): Use it.
* src/gram.h (rule_t): `number' is a new member.
* src/reader.c (packgram): Set it.
* src/reduce.c (reduce_grammar_tables): Move the useless rules at
the end of `rules', and count them out of `nrules'.
(reduce_output, dump_grammar): Adjust.
* src/print.c (print_grammar): It is no longer needed to check for
the usefulness of a rule, as useless rules are beyond `nrules + 1'.
* tests/reduce.at (Reduced Automaton): New test.
* src/nullable.c, src/output.c, src/print.c, src/print_graph.c,
* src/reader.c, src/reduce.c: Let rule_t.rhs point directly to the
RHS, instead of being an index in RITEMS.
* data/bison.simple, data/bison.c++: Handle the `#define' part, so
that we can move to enums for instance.
* src/output.c (token_definitions_output): Output a list of
`token-name, token-number' instead of the #define.
(output_skeleton): Name this list `b4_tokens', not `b4_tokendefs'.
* tests/output.at (AT_CHECK_OUTPUT): Likewise.
* tests/headers.at (AT_TEST_CPP_GUARD_H): Ditto.
* tests/semantic.at (Parsing Guards): Similarly.
* src/reader.at (readgram): Complain if the last rule is not ended
with a semi-colon.
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.
