While the levels x86-64 x86-64-v2 x86-64-v3 x86-64-v4 are supported values by -march option, they are actually only aliases for k8 CPU. That said, they are more closer to __builtin_cpu_supports function and we decided to implement it there. PR target/101696 gcc/ChangeLog: * common/config/i386/cpuinfo.h (cpu_indicator_init): Add support for x86-64 micro levels for __builtin_cpu_supports. * common/config/i386/i386-cpuinfo.h (enum feature_priority): Add priorities for the micro-arch levels. (enum processor_features): Add new features. * common/config/i386/i386-isas.h: Add micro-arch features. * config/i386/i386-builtins.c (get_builtin_code_for_version): Support the micro-arch levels by callsing __builtin_cpu_supports. * doc/extend.texi: Document that the levels are support by __builtin_cpu_supports. gcc/testsuite/ChangeLog: * g++.target/i386/mv30.C: New test. * gcc.target/i386/mvc16.c: New test. * gcc.target/i386/builtin_target.c (CHECK___builtin_cpu_supports): New.
