From 3cb2cb800ff6bc19ed4e066af47b0b9994cf13c4 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Tue, 4 Dec 2012 22:25:16 +0000 Subject: Speed up the AllocationOrder class a bit. Allow the central functions to be inlined, and use the argumentless isHint() function when possible. llvm-svn: 169319 --- llvm/lib/CodeGen/AllocationOrder.cpp | 19 +------------------ 1 file changed, 1 insertion(+), 18 deletions(-) (limited to 'llvm/lib/CodeGen/AllocationOrder.cpp') diff --git a/llvm/lib/CodeGen/AllocationOrder.cpp b/llvm/lib/CodeGen/AllocationOrder.cpp index a76791025d9..94754a0d35a 100644 --- a/llvm/lib/CodeGen/AllocationOrder.cpp +++ b/llvm/lib/CodeGen/AllocationOrder.cpp @@ -35,6 +35,7 @@ AllocationOrder::AllocationOrder(unsigned VirtReg, const TargetRegisterInfo *TRI = &VRM.getTargetRegInfo(); Order = RegClassInfo.getOrder(MF.getRegInfo().getRegClass(VirtReg)); TRI->getRegAllocationHints(VirtReg, Order, Hints, MF, &VRM); + rewind(); DEBUG({ if (!Hints.empty()) { @@ -45,21 +46,3 @@ AllocationOrder::AllocationOrder(unsigned VirtReg, } }); } - -bool AllocationOrder::isHint(unsigned PhysReg) const { - return std::find(Hints.begin(), Hints.end(), PhysReg) != Hints.end(); -} - -unsigned AllocationOrder::next() { - if (Pos < Hints.size()) - return Hints[Pos++]; - ArrayRef::iterator I = Order.begin() + (Pos - Hints.size()); - ArrayRef::iterator E = Order.end(); - while (I != E) { - unsigned Reg = *I++; - ++Pos; - if (!isHint(Reg)) - return Reg; - } - return 0; -} -- cgit v1.2.3
