From acb7bf3cf985b38a505eb3a5be0569ecab7770ba Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Wed, 13 Feb 2019 18:21:36 +0000 Subject: [PATCH] [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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@353963 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/Host.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/lib/Support/Host.cpp b/lib/Support/Host.cpp index 1b907bc6284..367fd188a1f 100644 --- a/lib/Support/Host.cpp +++ b/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; -- 2.40.0
