Hi: This patch is about to add Sapphire Rapids and Alder Lake to GCC. Sapphire Rapids is based on Cooper Lake and plus ISA MOVDIRI/MOVDIR64B/AVX512VP2INTERSECT/ENQCMD/CLDEMOTE/PTWRITE/WAITPKG/SERIALIZE/TSXLDTRK. Alder Lake is based on Skylake and plus ISA CLDEMOTE/PTWRITE/WAITPK/SERIALIZE.
For detailed information, please refer to https://software.intel.com/content/dam/develop/public/us/en/documents/architecture-instruction-set-extensions-programming-reference.pdf Bootstrap is ok, and no regressions for i386/x86-64 testsuite. OK for master? gcc/ChangeLog * common/config/i386/cpuinfo.h (get_intel_cpu): Handle sapphirerapids. * common/config/i386/i386-common.c (processor_names): Add sapphirerapids and alderlake.
