From eece9dc81cedf0cda5c356c180f60d91c99920fc Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Fri, 20 Apr 2012 00:38:45 +0000 Subject: Revert r155136 "Defer some shl transforms to DAGCombine." While the patch was perfect and defect free, it exposed a really nasty bug in X86 SelectionDAG that caused an llc crash when compiling lencod. I'll put the patch back in after fixing the SelectionDAG problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155181 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/InstCombine/2010-11-01-lshr-mask.ll | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'test/Transforms/InstCombine/2010-11-01-lshr-mask.ll') diff --git a/test/Transforms/InstCombine/2010-11-01-lshr-mask.ll b/test/Transforms/InstCombine/2010-11-01-lshr-mask.ll index eb28994756..441d5f9b0b 100644 --- a/test/Transforms/InstCombine/2010-11-01-lshr-mask.ll +++ b/test/Transforms/InstCombine/2010-11-01-lshr-mask.ll @@ -5,8 +5,8 @@ define i32 @main(i32 %argc) nounwind ssp { entry: %tmp3151 = trunc i32 %argc to i8 -; CHECK: %tmp3163 = shl i8 %tmp3162, 6 -; CHECK: and i8 %tmp3163, 64 +; CHECK: %tmp3162 = shl i8 %tmp3151, 5 +; CHECK: and i8 %tmp3162, 64 ; CHECK-NOT: shl ; CHECK-NOT: shr %tmp3161 = or i8 %tmp3151, -17 @@ -38,8 +38,8 @@ bb: %tmp10 = lshr i8 %tmp8, 7 %tmp11 = shl i8 %tmp10, 5 -; CHECK: %tmp10 = lshr i8 %tmp8, 7 -; CHECK: %tmp11 = shl nuw nsw i8 %tmp10, 5 +; CHECK: %0 = lshr i8 %tmp8, 2 +; CHECK: %tmp11 = and i8 %0, 32 %tmp12 = xor i8 %tmp11, %tmp9 ret i8 %tmp12 -- cgit v1.2.3
