Hi Gerald,
Do you think it is ok to copypaste it from GCC-6?
GCC now supports the Intel CPU, named Cannonlake through -march=cannonlake. The switch enables the following ISA extensions: AVX512VBMI, AVX512IFMA, SHA.
GCC now supports the Intel CPU, named and Icelake through -march=icelake. The switch enables the following ISA extensions: AVX512VNNI, GFNI, VAES, AVX512VBMI2, VPCLMULQDQ, AVX512BITALG, RDPID, AVX512VPOPCNTDQ.
Thanks,
Julia
