From 4969310052f45b1e2e5d21735e38641a20be0e21 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Mon, 4 Feb 2013 15:19:18 +0000 Subject: SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors. This required disabling a PowerPC optimization that did the following: input: x = BUILD_VECTOR lowered to: tmp = BUILD_VECTOR x = ADD tmp, tmp The add now gets folded immediately and we're back at the BUILD_VECTOR we started from. I don't see a way to fix this currently so I left it disabled for now. Fix some trivially foldable X86 tests too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174325 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/blend-msb.ll | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'test/CodeGen/X86/blend-msb.ll') diff --git a/test/CodeGen/X86/blend-msb.ll b/test/CodeGen/X86/blend-msb.ll index 34445428ea..2b6b9ef8f3 100644 --- a/test/CodeGen/X86/blend-msb.ll +++ b/test/CodeGen/X86/blend-msb.ll @@ -5,7 +5,8 @@ ; shifting the needed bit to the MSB, and not using shl+sra. ;CHECK: vsel_float -;CHECK: pslld +;CHECK: movl $-2147483648 +;CHECK-NEXT: movd ;CHECK-NEXT: blendvps ;CHECK: ret define <4 x float> @vsel_float(<4 x float> %v1, <4 x float> %v2) { @@ -14,7 +15,8 @@ define <4 x float> @vsel_float(<4 x float> %v1, <4 x float> %v2) { } ;CHECK: vsel_4xi8 -;CHECK: pslld +;CHECK: movl $-2147483648 +;CHECK-NEXT: movd ;CHECK-NEXT: blendvps ;CHECK: ret define <4 x i8> @vsel_4xi8(<4 x i8> %v1, <4 x i8> %v2) { -- cgit v1.2.3
