H.J. Lu 6c35d16a39 x86: Share _isa_names_table and use cpuinfo.h
Both driver-i386.c and libgcc use CPUID to detect the processor name
as well as available ISAs.  To detect the same processor or ISAs, the
same detection logic is duplicated in 2 places.  Sometimes only one place
was up to date or got it right.  Sometimes both places got it wrong.

1. Add common/config/i386/i386-isas.h to define _isa_names_table.
2. Use isa_names_table to auto-generate ISA command-line options.
3. Use isa_names_table to auto-generate __builtin_cpu_supports tests.
4. Use common/config/i386/cpuinfo.h to check available ISAs and detect
newer Intel processors in driver-i386.c and builtin_target.c.
5. Detection of AMD processors and older processors in driver-i386.c is
unchanged.

gcc/

	PR target/95843
	* common/config/i386/i386-isas.h: New file.  Extracted from
	gcc/config/i386/i386-builtins.c.
	(_isa_names_table): Add option.
	(ISA_NAMES_TABLE_START): New.
	(ISA_NAMES_TABLE_END): Likewise.
	(ISA_NAMES_TABLE_ENTRY): Likewise.
	(isa_names_table): Defined with ISA_NAMES_TABLE_START,

	from enum processor_features.
	* config/i386/driver-i386.c: Include
	"common/config/i386/cpuinfo.h" and
	"common/config/i386/i386-isas.h".
	(has_feature): New macro.
	(host_detect_local_cpu): Call cpu_indicator_init to get CPU
	features.  Use has_feature to detect processor features.  Call
	Call get_intel_cpu to get the newer Intel CPU name.  Use
	isa_names_table to generate command-line options.
	* config/i386/i386-builtins.c: Include
	"common/config/i386/i386-isas.h".
	(_arch_names_table): Removed.
	(isa_names_table): Likewise.

gcc/testsuite/

	PR target/95843
	* gcc.target/i386/builtin_target.c: Include <stdlib.h>,
	../../../common/config/i386/i386-cpuinfo.h and
	../../../common/config/i386/cpuinfo.h.
	(check_amd_cpu_model): Removed.
	(check_intel_cpu_model): Likewise,
	(CHECK___builtin_cpu_is): New.
	(gcc_assert): New.  Defined as assert.
	(gcc_unreachable): New.  Defined as abort.
	(inline): New.  Defined as empty.
	(ISA_NAMES_TABLE_START): Likewise.
	(ISA_NAMES_TABLE_END): Likewise.
	(ISA_NAMES_TABLE_ENTRY): New.
	(check_features): Include
	"../../../common/config/i386/i386-isas.h".
	(check_detailed): Call cpu_indicator_init.  Always call
	check_features.  Call get_amd_cpu instead of check_amd_cpu_model.
	Call get_intel_cpu instead of check_intel_cpu_model.

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.
