| * Convert underscores to dashes in some %define variable names.Joel E. Denny2009-04-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, just api.push-pull and lr.keep-unreachable-states. Maintain old names for backward compatibility. * NEWS (2.5): Document. * data/c.m4 (b4_identification): Update comment. * data/yacc.c: Update access. * doc/bison.texinfo: Update. * etc/bench.pl.in (bench_grammar): Update use. * src/files.c (tr): Move to... * src/getargs.c, src/getargs.h (tr): ... here because I can't think of a better place to expose it. My logic is that, for all uses of tr so far, command-line arguments can be involved, and getargs.h is already included. * src/main.c (main): Update access. * src/muscle_tab.c (muscle_percent_define_insert): Convert old variable names to new variable names before assigning value. * src/reader.c (reader): Update setting default. * tests/calc.at: Update uses. * tests/conflicts.at (Unreachable States After Conflict Resolution): Update use. * tests/input.at (%define enum variables): Update use. (%define backward compatibility): New test group. * tests/push.at: Update uses. * tests/reduce.at: Update uses. * tests/torture.at: Update uses.
* | tests: fix regressions.Akim Demaille2012-02-211-1/+1
| | | | | | | | | | | | | | | | | | | | Exit status 63 is documented for version-mismatch. * bootstrap.conf (gnulib_modules): Remove sysexits. * src/system.h (EX_MISMATCH): Define. * src/parse-gram.y (version_check): Use it instead of EX_CONFIG. Missing includes. * tests/calc.at, tests/named-refs.at: Include assert.h.
* | maint: avoid "magic number exit".Akim Demaille2012-02-181-2/+1
| | | | | | | | | | | | | | | | | | * cfg.mk (local-checks-to-skip): No longer skip it. * bootstrap.conf (gnulib_modules): Add sysexits. * doc/bison.texinfo, etc/bench.pl.in, src/parse-gram.y, * src/system.h, tests/calc.at, tests/named-refs.at: Use assert where appropriate instead of "if (...) exit". Use symbolic exit status elsewhere.
* | maint: remove obsolete file.Akim Demaille2012-02-141-16/+0
| | | | | | | | | | * etc/make-ChangeLogs: Remove (used for rcs to cvs migration!). Reported by Tys Lefering.
* | build: generalize etc/prefix-gnulib-mkJim Meyering2012-01-231-4/+72
| | | | | | | | | | | | | | | | | | 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.
* | build: manually update bootstrap from gnulib, and adaptJim Meyering2012-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 "\".

* | global: remove unnecessary horizontal tabs.Joel E. Denny2011-07-242-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change was made by applying emacs' untabify function to nearly all files in Bison's repository. Required tabs in make files, ChangeLog, regexps, and test code were manually skipped. Other notable exceptions and changes are listed below. * bootstrap: Skip because we sync this with gnulib. * data/m4sugar/foreach.m4 * data/m4sugar/m4sugar.m4: Skip because we sync these with Autoconf. * djgpp: Skip because I don't know how to test djgpp properly, and this code appears to be unmaintained anyway. * README-hacking (Hacking): Specify that tabs should be avoided where not required.

If someone needs these files, they can resurrect them. * .gitignore, build-aux/.gitignore, doc/.gitignore, lib/.gitignore: * m4/.gitignore, po/.gitignore, runtime-po/.gitignore: Omit leading '/', since bootstrap omits it. Adjust file names to match current contents better. * bootstrap: Sync from gnulib: this contains the new gnulib_mk_hook installed just for us. * bootstrap.conf (excluded_files): Don't exclude codeset.m4, glibc21.m4, inttypes_h.m4, size_max.m4, xsize.m4, as they are now needed somehow. Don't have time to look into why. (gnulib_modules): Change malloc to malloc-gnu. Do we really assume the GNU malloc behavior, where malloc (0) != NULL unless we're out of storage? If not, we can omit malloc-gnu; but for now I left it in to be safe. (vc_ignore): Remove. (gnulib_mk_hook): New function. * README-hacking: Renamed from HACKING, since gnulib bootstrap now uses that convention.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is used to help the user catch cases where some value gets ovewritten by a new one. This should not happen, as this will probably leak. Unfortunately this uncovered a bug in the C++ parser itself: the lookahead value was not destroyed between two calls to yylex. For instance if the previous lookahead was a std::string, and then an int, then the value of the std::string was correctly taken (i.e., the lookahead was now an empty string), but std::string structure itself was not reclaimed. This is now done in variant::build(other&) (which is used to take the value of the lookahead): other is not only stolen from its value, it is also destroyed. This incurs a new performance penalty of a few percent, and union becomes faster again. * data/lalr1-fusion.cc (variant::build(other&)): Destroy other. (b4_variant_if): New. (variant::built): New. Use it whereever the status of the variant changes. * etc/bench.pl.in: Check the penalty of %define assert.
* | Use "%define variant" in bench.pl.Akim Demaille2008-11-071-15/+6

| | | | | | | | | | | | | | | | * etc/bench.pl.in (&run, &generate_grammar): New. Rename the grammar generating functions for consistency. Change the interface so that the list of benches to run is passed as (optionless) arguments. (&compile): Use &run.
