* bootstrap.conf (gnulib_modules): Add assert module.
* src/system.h (aver): Define as assert, and summarize the
discussion on this issue.
(cherry picked from commit ca01f454f0)
Conflicts:
src/system.h
* tests/push.at: Remove "Push Parsing: " from test group titles
because these are already under the banner "Push Parsing Tests".
(cherry picked from commit 00d80a9ced)
And skip tests if perl is not available. This is better than
playing tricks with shell portability. Suggested by Akim
Demaille.
* tests/input.at (Bad escapes in literals): Use it here for special
characters.
(cherry picked from commit b70c7fb4e1)
Conflicts:
tests/input.at
* src/output.c (ARRAY_CARDINALITY): New macro, copied from
argmatch.h.
(output_skeleton): Use it.
Suggested by Akim Demaille.
Signed-off-by: Eric Blake <ebb9@byu.net>
* m4/m4.m4: Copy from autoconf 2.64.
* configure.ac (M4_GNU_OPTION): New define.
* src/output.c (output_skeleton): Use it to resolve FIXME.
* NEWS: Mention this.
Signed-off-by: Eric Blake <ebb9@byu.net>
Discussed starting at
<http://lists.gnu.org/archive/html/bison-patches/2009-08/msg00036.html>.
* src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER):
For a \0 and similar escape sequences meaning the null
character, report an invalid escape sequence instead of an
invalid null character because the latter does not actually
appear in the user's input.
In all escape sequence complaints, don't escape the initial
backslash, and don't quote when the sequence appears at the end
of the complaint line unless there's whitespace that quotearg
won't escape.
Consistently say "invalid" not "unrecognized".
* tests/input.at (Bad escapes in literals): New.
(cherry picked from commit c2724603c9)
Conflicts:
tests/input.at
Reported by Bill Allombert.
* doc/bison.texinfo: Set fill-column to 76.
(Location Type): Document the use of %initial-action to initialize
yylloc.
(cherry picked from commit d59e456dbf)
* gnulib: Update.
* .x-update-copyright (COPYING): Add as it's no longer implied
when .x-update-copyright is present.
* cfg.mk (update-copyright-local): Remove, now ignored.
(update-copyright): Declare update-b4-copyright as a dependency.
(cherry picked from commit c67e466f9d)
Bison was uselessly requiring the formatstring macros from
gettext, which resulted in mo files not being installed on systems
that perfectly supported Bison mo files. Lower the requirement.
http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html
* configure.ac: Require need-ngettext instead of
need-formatstring-macros.
Reported by Martin Jabocs.
Suggested by Bruno Haible.
* INSTALL: Restructure.
(Internationalization): New.
* build-aux/update-b4-copyright: In warnings, report line
numbers rather than character positions.
* cfg.mk (update-copyright-local): Set to update-b4-copyright so
that update-copyright runs it.
* gnulib: Update.
(cherry picked from commit a1a9422d4a)
* build-aux/update-b4-copyright: Do not accept 2-digit
UPDATE_COPYRIGHT_YEAR, which was not handled correctly.
Don't accept a `[' in a b4_copyright argument.
Format code more consistently.
Don't assume b4*copyright never occurs.
(cherry picked from commit 0b61a8ec18)
Reported by Alex Rozenman. This warning shows up with gcc-4.3.0
and later.
* src/scan-code.l: Add "%option noinput", which I cannot find in
the Flex manual, but which Flex has supported since at least as
far back as 2.5.4. However, if any of our developers still use
Flex 2.5.4, they'll need to stop configuring with
--enable-gcc-warnings because "%option noinput" didn't work
correctly until Flex 2.5.6.
* src/scan-gram.l: Likewise.
* src/scan-skel.l: Likewise.
* examples/calc++/Makefile.am (calc.stamp): New.
Depend on it to create the sources of calc++ so that concurrent
builds don't launch several "extexi" in parallel.
Not only this is inefficient, this also builds incorrect sources
with several extractions mixed together.
Cherry-picked from 5ece73eaa1.
* gnulib: Update to latest.
* lib/.cvsignore, lib/.gitignore, m4/.cvsignore,
* m4/.gitignore: Regen.
* src/symtab.c (symbol_from_uniqstr, semantic_type_from_uniqstr):
Call xalloc_die on hash_insert failures.
Requested by the new __warn_unused_result__ attribute of
hash_insert.
* data/c++.m4 (b4_namespace_close): Don't let it be printed
among the closing braces here. This fix might make the
generated code easier to debug, but otherwise it should be
insignificant because a trailing `:' is a C++ error already.
(cherry picked from commit 8c221795af)
* build-aux/cross-options.pl: As in --help output, write optional
arguments as [=ARG] not =[ARG].
* doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
* build-aux/cross-options.pl: The argument ends at the first
space, not the first non-symbol character.
Use @var for each word appearing the argument description.
(cherry picked from commit 74eae918c3)
If the first m4 in $PATH is wrong, it keeps looking. Moreover, its
requirements for a correct m4 are stricter.
* m4/m4.m4: Replace with Autoconf 2.63's m4/m4.m4.
* configure.ac: Update to use AC_PROG_GNU_M4.
Reported by Eric Blake.
Reported by Akim Demaille at
<http://lists.gnu.org/archive/html/bug-bison/2007-12/msg00001.html>
and discussed again starting at
<http://lists.gnu.org/archive/html/bison-patches/2008-11/msg00102.html>.
* data/bison.m4 (b4_percent_define_default): Leave syncline blank
because location information is bogus.
Use angle brackets to delimit fake file name because square brackets
look like over-quoted m4. Choose a better fake file name.
Use negative line numbers.
* src/muscle_tab.c (muscle_percent_define_default): Likewise.
* src/location.c (location_print): If line for a boundary is negative,
only print that boundary's file name.
* src/location.h: Document that.
* tests/skeletons.at (%define Boolean variables: invalid skeleton
defaults): Update output.
