As mentioned in the PR, we do miss supports target micro-architectures in target and target_clone attribute. 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.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
