ACEv1 is a new ISA documented here:
https://x86ecosystem.org/resource/ai-compute-extensions-ace-specification/
In this patch, we will first add initial support
for ACEv1. The instruction support will come afterwards.
gcc/ChangeLog:
* common/config/i386/cpuinfo.h
(get_available_features): Add ACEV1.
* common/config/i386/i386-common.cc
(OPTION_MASK_ISA2_ACEV1_SET): New.
(OPTION_MASK_ISA2_AVX10V2AUX_UNSET): Disable ACEV1.
(OPTION_MASK_ISA2_ACEV1_UNSET): New.
(ix86_handle_option): Handle ACEV1.
* common/config/i386/i386-cpuinfo.h
(enum processor_features): Add FEATURE_ACEV1.
* common/config/i386/i386-isas.h: Handle acev1.
* config/i386/cpuid.h (bit_ACE): New.
* config/i386/i386-c.cc (ix86_target_macros_internal):
Handle acev1.
* config/i386/i386-isa.def (ACEV1): Add DEF_PTA.
* config/i386/i386-options.cc (isa2_opts): Handle acev1.
(ix86_valid_target_attribute_inner_p): Ditto.
* config/i386/i386.opt: Add macev1.
* config/i386/i386.opt.urls: Regenerated.
* doc/extend.texi: Add acev1 documentation.
* doc/invoke.texi: Ditto.
* doc/sourcebuild.texi: Ditto.
