Hello, This patch introduces `-mavx512vl' option to GCC Bootstrapped. gcc/ * common/config/i386/i386-common.c (OPTION_MASK_ISA_AVX512VL_SET): Define. (OPTION_MASK_ISA_AVX512F_UNSET): Update. (ix86_handle_option): Handle OPT_mavx512vl. * config/i386/cpuid.h (bit_AVX512VL): Define. * config/i386/driver-i386.c (host_detect_local_cpu): Detect avx512vl, set -mavx512vl accordingly. * config/i386/i386-c.c (ix86_target_macros_internal): Handle OPTION_MASK_ISA_AVX512VL. * config/i386/i386.c (ix86_target_string): Handle -mavx512vl. (ix86_option_override_internal): Define PTA_AVX512VL, handle PTA_AVX512VL and OPTION_MASK_ISA_AVX512VL. (ix86_valid_target_attribute_inner_p): Handle OPT_mavx512vl. * config/i386/i386.h (TARGET_AVX512VL): Define. (TARGET_AVX512VL_P(x)): Ditto. * config/i386/i386.opt: Add mavx512vl. Is it ok for main trunk? -- Thanks, K
