--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
The run-time CPUID checks in

FAIL: gcc.target/i386/avx512vl-vpermb-2.c execution test
FAIL: gcc.target/i386/avx512vl-vpermi2b-2.c execution test
FAIL: gcc.target/i386/avx512vl-vpermt2b-2.c execution test
FAIL: gcc.target/i386/avx512vl-vpmaddhuq-2.c execution test
FAIL: gcc.target/i386/avx512vl-vpmaddluq-2.c execution test
FAIL: gcc.target/i386/avx512vl-vpmultishiftqb-2.c execution test

are incorrect. avx512vl-vpermb-2.c has

#define AVX512VL
#define AVX512F_LEN 256
#define AVX512F_LEN_HALF 128
#include "avx512vbmi-vpermb-2.c"

It runs on processors with AVX512VL.  But avx512vbmi-vpermb-2.c has

#define AVX512VBMI

#include "avx512f-helper.h"

which needs AVX512VBMI.
