From 33ae80bff75a1f973b772e542c42fff92a3a8b07 Mon Sep 17 00:00:00 2001 From: Gabor Greif Date: Thu, 15 Apr 2010 20:51:13 +0000 Subject: reapply r101364, which has been backed out in r101368 with a fix 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 llvm-svn: 101397 --- llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp') diff --git a/llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp b/llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp index 861cf92d281..1812e1d3a21 100644 --- a/llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp +++ b/llvm/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 v1.2.3
