From 324bec558e95584e8c1997575ae9d75978af59f1 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 1 Oct 2020 10:08:24 +0200 Subject: PR target/97250: i386: Add support for x86-64-v2, x86-64-v3, x86-64-v4 levels for x86-64 These micro-architecture levels are defined in the x86-64 psABI: https://gitlab.com/x86-psABIs/x86-64-ABI/-/commit/77566eb03bc6a326811cb7e9 PTA_NO_TUNE is introduced so that the new processor alias table entries do not affect the CPU tuning setting in ix86_tune. The tests depend on the macros added in commit 92e652d8c21bd7e66cbb0f900 ("i386: Define __LAHF_SAHF__ and __MOVBE__ macros, based on ISA flags"). gcc/: PR target/97250 * config/i386/i386.h (PTA_NO_TUNE, PTA_X86_64_BASELINE) (PTA_X86_64_V2, PTA_X86_64_V3, PTA_X86_64_V4): New. * common/config/i386/i386-common.c (processor_alias_table): Add "x86-64-v2", "x86-64-v3", "x86-64-v4". * config/i386/i386-options.c (ix86_option_override_internal): Handle new PTA_NO_TUNE processor table entries. * doc/invoke.texi (x86 Options): Document new -march values. gcc/testsuite/: PR target/97250 * gcc.target/i386/x86-64-v2.c: New test. * gcc.target/i386/x86-64-v3.c: New test. * gcc.target/i386/x86-64-v3-haswell.c: New test. * gcc.target/i386/x86-64-v3-skylake.c: New test. * gcc.target/i386/x86-64-v4.c: New test. --- gcc/common/config/i386/i386-common.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) (limited to 'gcc/common') diff --git a/gcc/common/config/i386/i386-common.c b/gcc/common/config/i386/i386-common.c index 1014214..62a620b 100644 --- a/gcc/common/config/i386/i386-common.c +++ b/gcc/common/config/i386/i386-common.c @@ -1795,9 +1795,13 @@ const pta processor_alias_table[] = PTA_MMX | PTA_3DNOW | PTA_3DNOW_A | PTA_SSE | PTA_FXSR, 0, P_NONE}, {"athlon-mp", PROCESSOR_ATHLON, CPU_ATHLON, PTA_MMX | PTA_3DNOW | PTA_3DNOW_A | PTA_SSE | PTA_FXSR, 0, P_NONE}, - {"x86-64", PROCESSOR_K8, CPU_K8, - PTA_64BIT | PTA_MMX | PTA_SSE | PTA_SSE2 | PTA_NO_SAHF | PTA_FXSR, - 0, P_NONE}, + {"x86-64", PROCESSOR_K8, CPU_K8, PTA_X86_64_BASELINE, 0, P_NONE}, + {"x86-64-v2", PROCESSOR_K8, CPU_GENERIC, PTA_X86_64_V2 | PTA_NO_TUNE, + 0, P_NONE}, + {"x86-64-v3", PROCESSOR_K8, CPU_GENERIC, PTA_X86_64_V3 | PTA_NO_TUNE, + 0, P_NONE}, + {"x86-64-v4", PROCESSOR_K8, CPU_GENERIC, PTA_X86_64_V4 | PTA_NO_TUNE, + 0, P_NONE}, {"eden-x2", PROCESSOR_K8, CPU_K8, PTA_64BIT | PTA_MMX | PTA_SSE | PTA_SSE2 | PTA_SSE3 | PTA_FXSR, 0, P_NONE}, -- cgit v1.1
