Martin Liska 8ea292591e i386: support micro-levels in target{,_clone} attrs [PR101696]
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.
