From 6829ca975d699e74b0bcdffd3c914a6831cf8a69 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Wed, 13 Feb 2019 18:21:36 +0000 Subject: [X86] Add 'fxsr' to the getHostCPUFeatures detection code. We implicitly mark this feature as enabled when the target is 64-bits, but our detection code for -march=native didn't support it so you can't detect it on 32-bit targets. llvm-svn: 353963 --- llvm/lib/Support/Host.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'llvm/lib/Support/Host.cpp') diff --git a/llvm/lib/Support/Host.cpp b/llvm/lib/Support/Host.cpp index 1b907bc6284..367fd188a1f 100644 --- a/llvm/lib/Support/Host.cpp +++ b/llvm/lib/Support/Host.cpp @@ -1259,6 +1259,7 @@ bool sys::getHostCPUFeatures(StringMap &Features) { Features["cmov"] = (EDX >> 15) & 1; Features["mmx"] = (EDX >> 23) & 1; + Features["fxsr"] = (EDX >> 24) & 1; Features["sse"] = (EDX >> 25) & 1; Features["sse2"] = (EDX >> 26) & 1; -- cgit v1.2.3
