Problems reported by Bruno Haible in:
http://lists.gnu.org/archive/html/bug-gnulib/2017-03/msg00078.html
* lib/stdalign.in.h (_Alignas):
* m4/stdalign.m4 (gl_STDALIGN_H):
Use octal, not decimal, for __HP_cc version. Perhaps HP formerly
used octal (as that is how they document it), but it is decimal in
practice now and the ancient implementations no longer matter.
* tests/test-stdalign.c (main) [__HP_cc && __ia64]: Skip test.
* build-aux/gendocs.sh (version):
* doc/gendocs_template:
* doc/gendocs_template_min:
* doc/gnulib.texi:
* lib/version-etc.c (COPYRIGHT_YEAR):
Update copyright dates by hand in templates and the like.
* all files: Run 'make update-copyright'.
* build-aux/gendocs.sh (version):
* doc/gendocs_template:
* doc/gendocs_template_min:
* doc/gnulib.texi:
* lib/version-etc.c (COPYRIGHT_YEAR):
Update copyright dates by hand in templates and the like.
* all files: Run 'make update-copyright'.
* tests/test-stdalign.c: Don't try to reduce alignment of long double
variables. That provokes errors like this from gcc-4.7.0 20111124:
error: '_Alignas' specifiers cannot reduce alignment of \
'static_longdouble_alignas'.
I think these problems were reported by Bruno Haible, in email
that I've unfortunately misplaced.
* doc/posix-headers/stdalign.texi (stdalign.h): Document more
shortcomings of MSVC and of Sun C 5.11.
* lib/stdalign.in.h (_Alignas): Omit bogus extra parenthesis
around __declspec arg.
* modules/stdalign-tests (Files): Add tests/macros.h.
* tests/test-stdalign.c: Do not include <stdlib.h>; no longer needed.
Include macros.h, for ASSERT.
(DECLARE_ALIGNED): Remove.
(TEST_ALIGNMENT): Define to 16 if alignment is supported (more likely
to catch bug), and to 1 if not (simplifies the rest of the code).
(CHECK_STATIC): Always declare the alignment test vars; that's simpler.
(CHECK_AUTO): Remove.
(CHECK_ALIGNED): Check only the alignment of the static vars,
since auto var alignment isn't supported by Sun C 5.11.
(CHECK_TYPES): Remove. All uses replaced by inline code, so that
ASSERT failures are easier to diagnose.
