From f152fe8d487c46873bbdd4abab43200f783e978b Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Fri, 1 Jun 2012 20:36:54 +0000 Subject: Switch some getAliasSet clients to MCRegAliasIterator. MCRegAliasIterator can optionally visit the register itself, allowing for simpler code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157837 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineCSE.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'lib/CodeGen/MachineCSE.cpp') diff --git a/lib/CodeGen/MachineCSE.cpp b/lib/CodeGen/MachineCSE.cpp index a63688e9ec..f2539baabd 100644 --- a/lib/CodeGen/MachineCSE.cpp +++ b/lib/CodeGen/MachineCSE.cpp @@ -216,11 +216,10 @@ bool MachineCSE::hasLivePhysRegDefUses(const MachineInstr *MI, if (MO.isDef() && (MO.isDead() || isPhysDefTriviallyDead(Reg, I, MBB->end()))) continue; - PhysRefs.insert(Reg); + for (MCRegAliasIterator AI(Reg, TRI, true); AI.isValid(); ++AI) + PhysRefs.insert(*AI); if (MO.isDef()) PhysDefs.push_back(Reg); - for (const uint16_t *Alias = TRI->getAliasSet(Reg); *Alias; ++Alias) - PhysRefs.insert(*Alias); } return !PhysRefs.empty(); -- cgit v1.2.3-18-g5258
