From 8a7beb80f0168876967c2aaebb4829ee1560250c Mon Sep 17 00:00:00 2001 From: Nadav Rotem Date: Wed, 11 May 2011 14:40:50 +0000 Subject: Fixes a bug in the DAGCombiner. LoadSDNodes have two values (data, chain). If there is a store after the load node, then there is a chain, which means that there is another user. Thus, asking hasOneUser would fail. Instead we ask hasNUsesOfValue on the 'data' value. llvm-svn: 131183 --- llvm/test/CodeGen/ARM/vstlane.ll | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) (limited to 'llvm/test/CodeGen/ARM') diff --git a/llvm/test/CodeGen/ARM/vstlane.ll b/llvm/test/CodeGen/ARM/vstlane.ll index d1bc15ad576..08b72325ed9 100644 --- a/llvm/test/CodeGen/ARM/vstlane.ll +++ b/llvm/test/CodeGen/ARM/vstlane.ll @@ -54,7 +54,8 @@ define void @vst1lanef(float* %A, <2 x float>* %B) nounwind { define void @vst1laneQi8(i8* %A, <16 x i8>* %B) nounwind { ;CHECK: vst1laneQi8: -;CHECK: vst1.8 {d17[1]}, [r0] +; // Can use scalar load.
