commit r15-5010-g4e91d0587200cf801b42abd74a837e0b3ce635d5 Author: Andrew Stubbs <a...@baylibre.com> Date: Thu Nov 7 11:23:41 2024 +0000 openmp: Fix max_vf testcases with -march=cascadelake Apparently we need to explicitly disable AVX, not just enabled SSE, to guarentee the 16-lane vectors we need for the pattern match. libgomp/ChangeLog: * testsuite/libgomp.c/max_vf-1.c: Add -mno-avx. gcc/testsuite/ChangeLog: * gcc.dg/gomp/max_vf-1.c: Add -mno-avx.
