From 33d6a3451bc8e0c6b7c4137d7b29596102a24627 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 7 Jul 2009 22:07:47 +0000 Subject: [PATCH] verify that the fcmp version of this works just as well as the vfcmp version. We actually get better code for this silly testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74954 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/vfcmp.ll | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/test/CodeGen/X86/vfcmp.ll b/test/CodeGen/X86/vfcmp.ll index 85b82a0ac8e..cfec1745831 100644 --- a/test/CodeGen/X86/vfcmp.ll +++ b/test/CodeGen/X86/vfcmp.ll @@ -11,3 +11,15 @@ define void @t(i32 %m_task_id, i32 %start_x, i32 %end_x) nounwind { store <2 x i8> %6, <2 x i8>* null ret void } + +define void @t2(i32 %m_task_id, i32 %start_x, i32 %end_x) nounwind { + %A = fcmp olt <2 x double> zeroinitializer, zeroinitializer ; <<2 x i64>>:1 [#uses=1] + sext <2 x i1> %A to <2 x i64> + extractelement <2 x i64> %1, i32 1 ; :2 [#uses=1] + lshr i64 %2, 63 ; :3 [#uses=1] + trunc i64 %3 to i1 ; :4 [#uses=1] + zext i1 %4 to i8 ; :5 [#uses=1] + insertelement <2 x i8> zeroinitializer, i8 %5, i32 1 ; <<2 x i8>>:6 [#uses=1] + store <2 x i8> %6, <2 x i8>* null + ret void +}
