From 85e6815d83d2b0027b5197aa17b5f32074bc9a8e Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Wed, 9 Jul 2008 20:12:26 +0000 Subject: [PATCH] Reuse the MO variable instead of recomputing it in RegAllocLocal. Keep RegAllocSimple in sync. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53351 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAllocLocal.cpp | 2 +- lib/CodeGen/RegAllocSimple.cpp | 16 ++++++++-------- 2 files changed, 9 insertions(+), 9 deletions(-) diff --git a/lib/CodeGen/RegAllocLocal.cpp b/lib/CodeGen/RegAllocLocal.cpp index c59d3b8477a..28836bd10a6 100644 --- a/lib/CodeGen/RegAllocLocal.cpp +++ b/lib/CodeGen/RegAllocLocal.cpp @@ -839,7 +839,7 @@ void RALocal::AllocateBasicBlock(MachineBasicBlock &MBB) { getVirtRegLastUse(DestVirtReg) = std::make_pair((MachineInstr*)0, 0); DOUT << " Assigning " << TRI->getName(DestPhysReg) << " to %reg" << DestVirtReg << "\n"; - MI->getOperand(i).setReg(DestPhysReg); // Assign the output register + MO.setReg(DestPhysReg); // Assign the output register } } diff --git a/lib/CodeGen/RegAllocSimple.cpp b/lib/CodeGen/RegAllocSimple.cpp index ce4b42071a7..9ad38405ae7 100644 --- a/lib/CodeGen/RegAllocSimple.cpp +++ b/lib/CodeGen/RegAllocSimple.cpp @@ -188,12 +188,12 @@ void RegAllocSimple::AllocateBasicBlock(MachineBasicBlock &MBB) { // Loop over uses, move from memory into registers. for (int i = MI->getNumOperands() - 1; i >= 0; --i) { - MachineOperand &op = MI->getOperand(i); + MachineOperand &MO = MI->getOperand(i); - if (op.isRegister() && op.getReg() && - TargetRegisterInfo::isVirtualRegister(op.getReg())) { - unsigned virtualReg = (unsigned) op.getReg(); - DOUT << "op: " << op << "\n"; + if (MO.isRegister() && MO.getReg() && + TargetRegisterInfo::isVirtualRegister(MO.getReg())) { + unsigned virtualReg = (unsigned) MO.getReg(); + DOUT << "op: " << MO << "\n"; DOUT << "\t inst[" << i << "]: "; DEBUG(MI->print(*cerr.stream(), TM)); @@ -201,7 +201,7 @@ void RegAllocSimple::AllocateBasicBlock(MachineBasicBlock &MBB) { // register in any given instruction unsigned physReg = Virt2PhysRegMap[virtualReg]; if (physReg == 0) { - if (op.isDef()) { + if (MO.isDef()) { int TiedOp = Desc.findTiedToSrcOperand(i); if (TiedOp == -1) { physReg = getFreeReg(virtualReg); @@ -222,8 +222,8 @@ void RegAllocSimple::AllocateBasicBlock(MachineBasicBlock &MBB) { Virt2PhysRegMap[virtualReg] = physReg; } } - MI->getOperand(i).setReg(physReg); - DOUT << "virt: " << virtualReg << ", phys: " << op.getReg() << "\n"; + MO.setReg(physReg); + DOUT << "virt: " << virtualReg << ", phys: " << MO.getReg() << "\n"; } } RegClassIdx.clear();
