--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:b49aedf6aed4911c8473738a88e839703f51386d commit r13-6784-gb49aedf6aed4911c8473738a88e839703f51386d Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 21 13:28:50 2023 +0100 testsuite: Fix up vect-simd-clone1[678]*.c tests [PR108898] As mentioned in the PR, vect-simd-clone-1[678]{,f}.c tests FAIL on x86_64-linux with -m64/-march=cascadelake or -m32/-march=cascadelake, there are 3 matches for the calls rather than expected two. As suggested by Richi, this patch changes those tests to use --param vect-epilogues-nomask=0 such that it is more predictable on how many calls will show up. In the non-[a-f] suffixed tests, the scan-tree-dump-times patterns were expecting 2 for non-aarch64 and 3 for aarch64, which is a puzzle for me, because vect_simd_clones effective target is apparently never true on aarch64 (just on x86 in some cases and on amdgcn; perhaps something to change for GCC14, but I guess too late for stage4). That said, I have looked at aarch64 dumps and see only 2 calls with --param vect-epilogues-nomask=0 and 3 with --param vect-epilogues-nomask=1 or without it, so I have tweaked those to always expect the same thing. Another thing is some tests uselessly had -fdump-tree-optimized in dg-options even when they don't scan anything there. Tested on x86_64-linux with make -j32 -k check-gcc RUNTESTFLAGS="vect.exp=gcc.dg/vect/vect-simd-clone-*.c \ --target_board='unix{-m64/-march=x86-64,-m64/-march=cascadelake,-m32/-march=i686,-m32/-march=cascadelake}'" and aarch64-linux (where all tests are UNSUPPORTED before/after). 2023-03-21 Jakub Jelinek <ja...@redhat.com> PR testsuite/108898 * gcc.dg/vect/vect-simd-clone-16.c: Add --param vect-epilogues-nomask=0 to dg-additional-options.
