H.J. Lu	f56c497d2b	x86: Move CPU_FEATURE{S}_{USABLE|ARCH}_P to isa-level.h ... Move X86_ISA_CPU_FEATURE_USABLE_P and X86_ISA_CPU_FEATURES_ARCH_P to where MINIMUM_X86_ISA_LEVEL and XXX_X86_ISA_LEVEL are defined.	2022-06-27 12:52:58 -07:00
Noah Goldstein	4fc321dc58	x86: Fix backwards Prefer_No_VZEROUPPER check in ifunc-evex.h ... Add third argument to X86_ISA_CPU_FEATURES_ARCH_P macro so the runtime CPU_FEATURES_ARCH_P check can be inverted if the MINIMUM_X86_ISA_LEVEL is not high enough to constantly evaluate the check. Use this new macro to correct the backwards check in ifunc-evex.h	2022-06-27 08:35:51 -07:00
Noah Goldstein	703f434108	x86: Add defines / utilities for making ISA specific x86 builds ... 1. Factor out some of the ISA level defines in isa-level.c to standalone header isa-level.h 2. Add new headers with ISA level dependent macros for handling ifuncs. Note, this file does not change any code. Tested with and without multiarch on x86_64 for ISA levels: {generic, x86-64-v2, x86-64-v3, x86-64-v4} And m32 with and without multiarch.	2022-06-22 19:41:35 -07:00
