From 46f6fe7a45964a4aa1c6a0f52b9991af8c30cb0b Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Tue, 4 Dec 2012 00:35:59 +0000 Subject: Remove VirtRegMap::getRegAllocPref(). Now that there can be multiple hint registers from targets, it doesn't make sense to have a function that returns 'the' preferred register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169190 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/VirtRegMap.cpp | 11 ----------- 1 file changed, 11 deletions(-) (limited to 'lib/CodeGen/VirtRegMap.cpp') diff --git a/lib/CodeGen/VirtRegMap.cpp b/lib/CodeGen/VirtRegMap.cpp index 820eed083b..cd012d2974 100644 --- a/lib/CodeGen/VirtRegMap.cpp +++ b/lib/CodeGen/VirtRegMap.cpp @@ -77,17 +77,6 @@ unsigned VirtRegMap::createSpillSlot(const TargetRegisterClass *RC) { return SS; } -unsigned VirtRegMap::getRegAllocPref(unsigned virtReg) { - std::pair Hint = MRI->getRegAllocationHint(virtReg); - unsigned physReg = Hint.second; - if (TargetRegisterInfo::isVirtualRegister(physReg) && hasPhys(physReg)) - physReg = getPhys(physReg); - if (Hint.first == 0) - return (TargetRegisterInfo::isPhysicalRegister(physReg)) - ? physReg : 0; - return TRI->ResolveRegAllocHint(Hint.first, physReg, *MF); -} - bool VirtRegMap::hasPreferredPhys(unsigned VirtReg) { unsigned Hint = MRI->getSimpleHint(VirtReg); if (!Hint) -- cgit v1.2.3
