newly created state.
Adjust to initialize first_state and last_state if needed.
Be sure to distinguish the initial from the final state.
(new_states): Create the itemset of the initial state, and use
new_state.
* src/closure.c (closure): Now that the initial state has its
items properly set, there is no need for a special case when
creating `ruleset'.
As a result, now the rule 0, reducing to $axiom, is visible in the
outputs. Adjust the test suite.
* tests/conflicts.at (Solved SR Conflicts)
(Unresolved SR Conflicts): Adjust.
* tests/regression.at (Web2c Report, Rule Line Numbers): Idem.
* tests/conflicts.at (S/R in initial): New.
reductions, then output the report anyway if requested, then die.
* src/symtab.c (bucket_new): Initialize `value' to -1, not 0.
* src/reader.c (eoftoken): New.
(parse_token_decl): If the token being defined has value `0', it
is the eoftoken.
(packsymbols): No longer hack `tags' to insert `$' by hand.
Be sure to preserve the value of the eoftoken.
(reader): Make sure eoftoken is defined.
Initialize nsyms to 0: now eoftoken is created just like the others.
* src/print.c (print_grammar): Don't special case the eof token.
* src/regression.at: Adjust: `$' has value 0, not -1, which was a
lie anyway, albeit pleasant.
* tests/calc.at: Exercise error messages with eoftoken.
Change the grammar so that empty input is invalid.
Adjust expectations.
When yyungeting, be sure to use a valid yylloc: use last_yylloc.
* src/lex.c (percent_table): Un-CPP out header_extension and
source_extension.
* src/files.c (compute_exts_from_gf): Compare pointers with NULL.
(compute_exts_from_src): Remove conditions. It restores priorities
between options.
the source or/and the header output file extension.
* src/files.c (compute_base_names): Remove initialisation of
src_extension and header_extension.
(compute_exts_from_gf): Update.
(compute_exts_from_src): Update.
(output_files): Update.
* src/reader.c (parse_header_extension_decl): New.
(parse_source_extension_decl): New.
(read_declarations): New case statements for the new tokens.
* src/lex.c (percent_table): Add entries for %source_extension
and %header_extension.
* src/lex.h (token_e): New tokens tok_hdrext and tok_srcext.
* doc/bison.1 (mandoc): Update.
* src/system.h (EXT_GUARD_C, EXT_STYPE_H): Remove .c and .h.
* src/files.c: Support output files extensions computing.
(src_extension): New static variable.
(header_extension): New static variable.
(tr): New function.
(get_extension_index): New function, gets the index of an extension
filename in a string.
(compute_exts_from_gf): New function, computes extensions from the
grammar file extension.
(compute_exts_from_src): New functions, computes extensions from the
C source file extension, file given by ``-o'' option.
(compute_base_names): Update.
(output_files): Update.
* src/getargs.c: Die on `-r'/`--raw'.
* src/lex.c (parse_percent_token): Die on `%raw'.
* src/reader.c (output_token_defines): Suppress call to `raw_flag'.
* tests/calc.at: Suppress test with option `--raw'.
* src/lex.c (percent_table): Also accept `%yacc',
`%fixed_output_files', `%defines', `%no_parser', `%verbose', and
`%debug'.
Handle the actions for `%semantic_parser' and `%pure_parser' here,
instead of returning a token.
* src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
* src/reader.c (read_declarations): Adjust.
* src/files.c (open_files): Don't call `compute_base_names', don't
compute `attrsfile' since they depend upon data which might be
*in* the input file now.
(output_files): Do it here.
* src/output.c (output_headers): Document the fact that this patch
introduces a guaranteed SEGV for semantic parsers.
* doc/bison.texinfo: Document them.
* tests/suite.at: Exercise these %options.
Update the `configure' tool chain.
* configure.in (XPFILE, XPFILE1, LOCALEDIR): Remove, handled by
src/makefile.am.
(VERSION_STRING): Use the third arg of AC_DEFINE_UNQUOTED.
(AC_OUTPUT): Add m4/Makefile.
Bump to bison 1.28a, 1.29 has never been released.
* acconfig.h (XPFILE, XPFILE1, LOCALEDIR): Remove, since they are
handled via src/Makefile.am.
(VERSION_STRING, PROTOTYPES, ENABLE_NLS, HAVE_CATGETS,
HAVE_GETTEXT, HAVE_LC_MESSAGES, HAVE_STPCPY): Remove, handled by
autoheader.
* Makefile.am (SUBDIRS): Add m4.
(ACLOCAL_AM_FLAGS): New variable.
(AUTOMAKE_OPTIONS): Add check-news.
* src/Makefile.am (bison.simple): Use awk to replace #line lines with
the proper line number and file name.
(DEFS): Propagate the location of bison library files and of the
locale files.
(INCLUDES): Added `-I ..' so that one can compile with srcdir !=
builddir.
* acinclude.m4: Remove, replaced by the directory m4.
* m4/Makefile.am (EXTRA_DIST): New variable.
* m4/gettext.m4: New file, from the fileutils.
* m4/lcmessage.m4: Likewise
* m4/progtest.m4: Likewise.
* m4/bison-decl.m4: New file, extracted from former acinclude.m4.
