From de7f1c251705cad8dc86f498402045235ff8aaaa Mon Sep 17 00:00:00 2001 From: Manman Ren Date: Mon, 13 Aug 2012 17:26:46 +0000 Subject: [PATCH] X86: when auto-detecting the subtarget features, make sure use IsIntel to detect Nehalem, Westmere and Sandy Bridge. AMD also has processor family 6. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161763 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86Subtarget.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/Target/X86/X86Subtarget.cpp b/lib/Target/X86/X86Subtarget.cpp index d7e3efc4f98..908785296d7 100644 --- a/lib/Target/X86/X86Subtarget.cpp +++ b/lib/Target/X86/X86Subtarget.cpp @@ -248,9 +248,9 @@ void X86Subtarget::AutoDetectSubtargetFeatures() { // If it's Nehalem, unaligned memory access is fast. // Include Westmere and Sandy Bridge as well. // FIXME: add later processors. - if ((Family == 6 && Model == 26) || + if (IsIntel && ((Family == 6 && Model == 26) || (Family == 6 && Model == 44) || - (Family == 6 && Model == 42)) { + (Family == 6 && Model == 42))) { IsUAMemFast = true; ToggleFeature(X86::FeatureFastUAMem); } -- 2.34.1
