A number of tests that depend on weak undefined symbols fail to require that support, and arrange to skip some targets and add special options to others on a test-by-test basis. Fix this by stating the requirement explicitly, and adding a proc to return any required options. Others rely on weak undefined symbols only to test for the availability of posix_memalign. Drop that in favor of dg effective target support for posix_memalign. for gcc/ChangeLog * doc/sourcebuild.texi (weak_undefined, posix_memalign): Document options and effective targets. for gcc/testsuite/ChangeLog * lib/target-supports.exp (add_options_for_weak_undefined): New. (check_effective_target_weak_undefined): Use it. (check_effective_target_posix_memalign): New. * gcc.dg/torture/pr53922.c: Drop skips and custom options in favor of effective target requirement and added options for weak_undefined symbols. * gcc.dg/torture/pr90020.c: Likewise. * gcc.dg/addr_equal-1.c: Likewise. * gcc.target/aarch64/aapcs64/aapcs64.exp: Likewise, for abitest.S-using tests. * gcc.dg/torture/pr60092.c: Likewise, but in favor of posix_memalign tests. * gcc.dg/vect/vect-tail-nomask-1.c: Likewise.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
