Hi! I've noticed the avx512f-vgetmantpd-2.c testcase eats lots of CPU time on KNL with -m32 and FAILs. The problem is excess precision, I've added -mfpmath=sse to it to fix that. Tested with make -j272 -k check-gcc RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} i386.exp' on KNL, ok for trunk? 2017-04-07 Jakub Jelinek <jakub@redhat.com> * gcc.target/i386/avx512f-vgetmantps-2.c: Add -mfpmath=sse to dg-options. * gcc.target/i386/avx512f-vgetmantpd-2.c: Likewise.
