Hi. Started from r272668 I see:
/tmp/ccqxwVjt.s: Assembler messages: /tmp/ccqxwVjt.s:22: Error: no such instruction: `vp2intersectq .LC1(%rip),%zmm0,%k0' /tmp/ccqxwVjt.s:33: Error: no such instruction: `vp2intersectd .LC3(%rip),%zmm0,%k0' compiler exited with status 1 FAIL: gcc.target/i386/avx512vp2intersect-2intersect-1b.c (test for excess errors) Excess errors: /tmp/ccqxwVjt.s:22: Error: no such instruction: `vp2intersectq .LC1(%rip),%zmm0,%k0' /tmp/ccqxwVjt.s:33: Error: no such instruction: `vp2intersectd .LC3(%rip),%zmm0,%k0' You'll need a dg-require detection I guess. Thanks, Martin
