Lu" Date: Mon, 27 Jun 2022 12:52:58 -0700 Subject: [PATCH] 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. --- sysdeps/x86/isa-ifunc-macros.h | 27 --------------------------- sysdeps/x86/isa-level.h | 24 ++++++++++++++++++++++++ 2 files changed, 24 insertions(+), 27 deletions(-) diff --git a/sysdeps/x86/isa-ifunc-macros.h b/sysdeps/x86/isa-ifunc-macros.h index d69905689b..f967a1bec6 100644 --- a/sysdeps/x86/isa-ifunc-macros.h +++ b/sysdeps/x86/isa-ifunc-macros.h @@ -56,31 +56,4 @@ # define X86_IFUNC_IMPL_ADD_V1(...) #endif -/* Both X86_ISA_CPU_FEATURE_USABLE_P and X86_ISA_CPU_FEATURES_ARCH_P - macros are wrappers for the the respective - CPU_FEATURE{S}_{USABLE|ARCH}_P runtime checks.
