re PR target/64393 (ICE: in extract_insn, at recog.c:2327 (unrecognizable insn) with -mavx512vbmi)
PR target/64393
gcc/
* common/config/i386/i386-common.c (OPTION_MASK_ISA_AVX512VBMI_SET):
Enable AVX512BW.
(OPTION_MASK_ISA_AVX512BW_UNSET): Disable AVX512VBMI.
* config/i386/i386.c (ix86_hard_regno_mode_ok): Don't check
AVX512VBMI, as it implies AVX512BW.
testsuite/
* gcc.target/i386/pr64393.c: New test.
