From d4034b2825a2a030893593327d67ca12b4e8a249 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Mon, 31 Aug 2009 21:54:16 +0000 Subject: [PATCH] If the tied registers are already the same, there is no need to change them. Move the code to make that change inside the conditional. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80630 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/TwoAddressInstructionPass.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/lib/CodeGen/TwoAddressInstructionPass.cpp b/lib/CodeGen/TwoAddressInstructionPass.cpp index 738b3c97acf..d8871f98ac7 100644 --- a/lib/CodeGen/TwoAddressInstructionPass.cpp +++ b/lib/CodeGen/TwoAddressInstructionPass.cpp @@ -985,13 +985,13 @@ bool TwoAddressInstructionPass::runOnMachineFunction(MachineFunction &MF) { mi->getOperand(i).getReg() == regB) mi->getOperand(i).setReg(regA); } - } - assert(mi->getOperand(ti).isDef() && mi->getOperand(si).isUse()); - mi->getOperand(ti).setReg(mi->getOperand(si).getReg()); - MadeChange = true; + assert(mi->getOperand(ti).isDef() && mi->getOperand(si).isUse()); + mi->getOperand(ti).setReg(mi->getOperand(si).getReg()); + MadeChange = true; - DEBUG(errs() << "\t\trewrite to:\t" << *mi); + DEBUG(errs() << "\t\trewrite to:\t" << *mi); + } } mi = nmi; -- 2.34.1
