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.
