From 69244300b8a0112efb44b6273ecea4ca6264b8cf Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 7 Jan 2008 01:56:04 +0000 Subject: Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects that it is cheap and efficient to get. Move a variety of predicates from TargetInstrInfo into TargetInstrDescriptor, which makes it much easier to query a predicate when you don't have TII around. Now you can use MI->getDesc()->isBranch() instead of going through TII, and this is much more efficient anyway. Not all of the predicates have been moved over yet. Update old code that used MI->getInstrDescriptor()->Flags to use the new predicates in many places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45674 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/VirtRegMap.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'lib/CodeGen/VirtRegMap.cpp') diff --git a/lib/CodeGen/VirtRegMap.cpp b/lib/CodeGen/VirtRegMap.cpp index 4ab293870a..967e2926a1 100644 --- a/lib/CodeGen/VirtRegMap.cpp +++ b/lib/CodeGen/VirtRegMap.cpp @@ -537,7 +537,7 @@ static bool InvalidateRegDef(MachineBasicBlock::iterator I, /// over. static void UpdateKills(MachineInstr &MI, BitVector &RegKills, std::vector &KillOps) { - const TargetInstrDescriptor *TID = MI.getInstrDescriptor(); + const TargetInstrDescriptor *TID = MI.getDesc(); for (unsigned i = 0, e = MI.getNumOperands(); i != e; ++i) { MachineOperand &MO = MI.getOperand(i); if (!MO.isRegister() || !MO.isUse()) @@ -966,7 +966,7 @@ void LocalSpiller::RewriteMBB(MachineBasicBlock &MBB, VirtRegMap &VRM) { NextMII = next(MII); MachineInstr &MI = *MII; - const TargetInstrDescriptor *TID = MI.getInstrDescriptor(); + const TargetInstrDescriptor *TID = MI.getDesc(); // Insert restores here if asked to. if (VRM.isRestorePt(&MI)) { @@ -1436,7 +1436,7 @@ void LocalSpiller::RewriteMBB(MachineBasicBlock &MBB, VirtRegMap &VRM) { // If this def is part of a two-address operand, make sure to execute // the store from the correct physical register. unsigned PhysReg; - int TiedOp = MI.getInstrDescriptor()->findTiedToSrcOperand(i); + int TiedOp = MI.getDesc()->findTiedToSrcOperand(i); if (TiedOp != -1) { PhysReg = MI.getOperand(TiedOp).getReg(); if (SubIdx) { -- cgit v1.2.3
