From d46fdb45387f46beeadc04472b3a66ad1da3aca1 Mon Sep 17 00:00:00 2001 From: Gabor Greif Date: Thu, 15 Apr 2010 10:49:53 +0000 Subject: rotate CallInst operands, i.e. move callee to the back of the operand array the motivation for this patch are laid out in my mail to llvm-commits: more efficient access to operands and callee, faster callgraph-construction, smaller compiler binary git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101364 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/InstCombine/InstCombineCompares.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'lib/Transforms/InstCombine/InstCombineCompares.cpp') diff --git a/lib/Transforms/InstCombine/InstCombineCompares.cpp b/lib/Transforms/InstCombine/InstCombineCompares.cpp index 861cf92..1812e1d 100644 --- a/lib/Transforms/InstCombine/InstCombineCompares.cpp +++ b/lib/Transforms/InstCombine/InstCombineCompares.cpp @@ -1423,7 +1423,7 @@ Instruction *InstCombiner::visitICmpInstWithInstAndIntCst(ICmpInst &ICI, switch (II->getIntrinsicID()) { case Intrinsic::bswap: Worklist.Add(II); - ICI.setOperand(0, II->getOperand(1)); + ICI.setOperand(0, II->getOperand(0)); ICI.setOperand(1, ConstantInt::get(II->getContext(), RHSV.byteSwap())); return &ICI; case Intrinsic::ctlz: @@ -1431,7 +1431,7 @@ Instruction *InstCombiner::visitICmpInstWithInstAndIntCst(ICmpInst &ICI, // ctz(A) == bitwidth(a) -> A == 0 and likewise for != if (RHSV == RHS->getType()->getBitWidth()) { Worklist.Add(II); - ICI.setOperand(0, II->getOperand(1)); + ICI.setOperand(0, II->getOperand(0)); ICI.setOperand(1, ConstantInt::get(RHS->getType(), 0)); return &ICI; } @@ -1440,7 +1440,7 @@ Instruction *InstCombiner::visitICmpInstWithInstAndIntCst(ICmpInst &ICI, // popcount(A) == 0 -> A == 0 and likewise for != if (RHS->isZero()) { Worklist.Add(II); - ICI.setOperand(0, II->getOperand(1)); + ICI.setOperand(0, II->getOperand(0)); ICI.setOperand(1, RHS); return &ICI; } -- cgit v1.1
