* data/lalr1.cc (parse): Catch syntax_error around yylex and
forward them to errlab1.
* tests/c++.at (Syntax error as exception): Check support for
syntax exceptions raised by the scanner.
* NEWS, doc/bison.texinfo: Document it.
* tests/local.mk (TESTSUITE_AT): Include plackage.m4.
Adjust dependencies.
Make testsuite.at its first argument.
(package.m4): Be silent.
(testsuite): Be silent.
Use $<.
* data/c.m4 (b4_parse_param_use): Also accept optional arguments
to "use".
Simplify callers.
* data/glr.c (yyuserAction): Simplify use of b4_parse_param_use.
(yy_reduce_print): Don't use b4_parse_param_use, as all the arguments
_are_ used.
* data/lalr1.cc (YY_SYMBOL_PRINT): Even when disabled, "use" the
symbol argument.
This neutralizes a warning in yypush_ when there are no symbols
with a semantic values.
(yy_destroy_): Remove useless "use" of yymsg.
See <http://lists.gnu.org/archive/html/bug-bison/2012-01/msg00120.html>.
Use quotearg as often as possible instead of leaving the choice of
the quotes to the translators. Use shorter messages. Factor similar
messages to a single format, to make localization easier.
* src/files.c, src/getargs.c, src/muscle-tab.c, src/reader.c
* src/scan-code.l, src/scan-gram.l, src/symtab.c:
Use quote() or quotearg_colon() on printf arguments instead of
quotes in the format string.
* data/bison.m4: Keep sync with the changes in muscle-tab.c.
* tests/skeletons.at, tests/input.at, tests/regression.at: Adjust
expected messages.
Standard output was never explicitly closed, so we could not
detect failure. Thus, bison would ignore the errors of writing
to a full file system and getting an I/O error on write, but only
for standard output, e.g., for --print-localedir, --print-datadir,
--help and some verbose output.
Now, "bison --print-datadir > /dev/full" reports the write failure:
bison: write error: No space left on device
Before, it would exit 0 with no diagnostic, implying success.
This is not an issue for "--output=-" or the other FILE-accepting
command-line options, because unlike most other GNU programs,
an output file argument of "-" is treated as the literal "./-",
rather than standard output.
* bootstrap.conf (gnulib_modules): Add closeout.
* src/main.c: Include "closeout.h".
Use atexit to ensure we close stdout.
* .gitignore: Ignore new files pulled in via gnulib-tool.
* lib/yyerror.c (yyerror): Use fputs and fputc rather than fprintf
with a mere "%s\n" format. Always return 0 now, on the assumption
that the return value was never used anyway.
Don't include <config.h> after all. This avoids a problem
reported by Thiru Ramakrishnan in
http://lists.gnu.org/archive/html/help-bison/2011-11/msg00000.html
* cfg.mk: Exempt lib/yyerror.c from the sc_require_config_h_first test.
* THANKS: Update.
This script hard-coded "libbison" and lib/gnulib.mk.
Adjust the script to require a --lib-name=$gnulib_name option
and a FILE argument like lib/$gnulib_mk.
Also add support for --help and --version.
* etc/prefix-gnulib-mk: Generalize.
* bootstrap.conf (bootstrap_post_import_hook): Update its invocation.
Updating to gnulib pulled in new quote and quotarg modules,
by which quoting is now done like 'this' rather than `this'.
That change induces many "make check" test failures. This change
adapts code and tests so that "make check" passes once again.
* src/scan-code.l: Quote like 'this', not like `this'.
* src/scan-gram.l: Likewise.
* src/symtab.c: Likewise.
* tests/actions.at: Adjust tests to match.
* tests/input.at: Likewise.
* tests/named-refs.at: Likewise.
* tests/output.at: Likewise.
* tests/regression.at: Likewise.
* lib/.gitignore: Regenerate.
* m4/.gitignore: Likewise.
Updating to the latest bootstrap from gnulib involves more of a
change than usual, and updating to the latest gnulib would involve
its own set of challenges with the upcoming quoting changes, so
we update bootstrap manually and separately.
* bootstrap: Update from gnulib.
* Makefile.am: Initialize more variables to empty, so that gnulib.mk
can append to them with "+=".
* bootstrap.conf (gnulib_mk_hook): Remove. No longer honored.
(bootstrap_post_import_hook): Instead, run the same command,
etc/prefix-gnulib-mk lib/$gnulib_mk, via slightly different API.
Temporarily disable "bootstrap_sync=true".
* etc/prefix-gnulib-mk: Don't prepend "lib/" to tokens like -I$(...
or "\".
* cfg.mk (exclude_file_name_regexp--sc_space_tab): Exempt
tests/input.at and tests/c++.at, since they appear to use
SP-TAB sequences deliberately.
* OChangeLog: Remove space-before-TAB.
* bootstrap.conf (gnulib_modules): Add gpl-3.0.
* doc/gpl-3.0.texi: Remove from version control, now that
we get it via gnulib.
* doc/.gitignore: Ignore it.
* lib/lbitset.c (lbitset_elt_find): Remove unnecessary test of "elt",
at a point where we know it is non-NULL, due to prior dereference.
Copyright (C) 1987-1988, 1991-2012 Free Software Foundation,
* lib/bitset_stats.c (bitset_stats_list): Remove declaration
and set of unused local, "type".
* lib/ebitset.c (ebitset_init): Likewise, for "size".
* lib/lbitset.c (lbitset_not): Likewise, for "elt".
This should help to avoid some portability problems. For example,
it would have revealed the empty unions fixed by the last patch
* configure.ac (WARN_CFLAGS_TESTS, WARN_CXXFLAGS_TEST): Implement.
* tests/synclines.at (AT_TEST_SYNCLINE): Avoid -pedantic warning
about an empty translation unit.
