--- Comment #48 from Uroš Bizjak <ubizjak at gmail dot com> --- The runtime testcase fails on non-AVX512F x86 targets due to: /* { dg-do run } */ /* { dg-options "-O3" } */ /* { dg-additional-options "-march=skylake-avx512" { target { x86_64-*-* i?86-*-* } } } */ but check_vect() only checks runtime support up to AVX2.
