From c9df025e33ac435adb3b3318d237c36ca7cec659 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Mon, 10 Jan 2011 02:58:51 +0000 Subject: Simplify a bunch of isVirtualRegister() and isPhysicalRegister() logic. These functions not longer assert when passed 0, but simply return false instead. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123155 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/TwoAddressInstructionPass.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/CodeGen/TwoAddressInstructionPass.cpp') diff --git a/lib/CodeGen/TwoAddressInstructionPass.cpp b/lib/CodeGen/TwoAddressInstructionPass.cpp index 63e6ec358d..a30279d57d 100644 --- a/lib/CodeGen/TwoAddressInstructionPass.cpp +++ b/lib/CodeGen/TwoAddressInstructionPass.cpp @@ -954,7 +954,7 @@ TryInstructionTransform(MachineBasicBlock::iterator &mi, if (LV) { for (unsigned i = 0, e = mi->getNumOperands(); i != e; ++i) { MachineOperand &MO = mi->getOperand(i); - if (MO.isReg() && MO.getReg() != 0 && + if (MO.isReg() && TargetRegisterInfo::isVirtualRegister(MO.getReg())) { if (MO.isUse()) { if (MO.isKill()) { -- cgit v1.2.3-18-g5258
