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/RegAllocFast.cpp | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'lib/CodeGen/RegAllocFast.cpp') diff --git a/lib/CodeGen/RegAllocFast.cpp b/lib/CodeGen/RegAllocFast.cpp index 6666d9aaf4..57934775e4 100644 --- a/lib/CodeGen/RegAllocFast.cpp +++ b/lib/CodeGen/RegAllocFast.cpp @@ -656,7 +656,8 @@ void RAFast::handleThroughOperands(MachineInstr *MI, MachineOperand &MO = MI->getOperand(i); if (!MO.isReg()) continue; unsigned Reg = MO.getReg(); - if (!Reg || TargetRegisterInfo::isPhysicalRegister(Reg)) continue; + if (!TargetRegisterInfo::isVirtualRegister(Reg)) + continue; if (MO.isEarlyClobber() || MI->isRegTiedToDefOperand(i) || (MO.getSubReg() && MI->readsVirtualRegister(Reg))) { if (ThroughRegs.insert(Reg)) @@ -688,7 +689,7 @@ void RAFast::handleThroughOperands(MachineInstr *MI, MachineOperand &MO = MI->getOperand(i); if (!MO.isReg()) continue; unsigned Reg = MO.getReg(); - if (!Reg || TargetRegisterInfo::isPhysicalRegister(Reg)) continue; + if (!TargetRegisterInfo::isVirtualRegister(Reg)) continue; if (MO.isUse()) { unsigned DefIdx = 0; if (!MI->isRegTiedToDefOperand(i, &DefIdx)) continue; @@ -794,7 +795,7 @@ void RAFast::AllocateBasicBlock() { MachineOperand &MO = MI->getOperand(i); if (!MO.isReg()) continue; unsigned Reg = MO.getReg(); - if (!Reg || TargetRegisterInfo::isPhysicalRegister(Reg)) continue; + if (!TargetRegisterInfo::isVirtualRegister(Reg)) continue; LiveDbgValueMap[Reg] = MI; LiveRegMap::iterator LRI = LiveVirtRegs.find(Reg); if (LRI != LiveVirtRegs.end()) @@ -909,7 +910,7 @@ void RAFast::AllocateBasicBlock() { MachineOperand &MO = MI->getOperand(i); if (!MO.isReg()) continue; unsigned Reg = MO.getReg(); - if (!Reg || TargetRegisterInfo::isPhysicalRegister(Reg)) continue; + if (!TargetRegisterInfo::isVirtualRegister(Reg)) continue; if (MO.isUse()) { LiveRegMap::iterator LRI = reloadVirtReg(MI, i, Reg, CopyDst); unsigned PhysReg = LRI->second.PhysReg; -- cgit v1.2.3-70-g09d2
