From a273442891ae20fd8192526132e3819ea9e5eda9 Mon Sep 17 00:00:00 2001 From: Jim Grosbach Date: Tue, 24 Aug 2010 19:05:43 +0000 Subject: Move enabling the local stack allocation pass into the target where it belongs. For now it's still a command line option, but the interface to the generic code doesn't need to know that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111942 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LocalStackSlotAllocation.cpp | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'lib/CodeGen/LocalStackSlotAllocation.cpp') diff --git a/lib/CodeGen/LocalStackSlotAllocation.cpp b/lib/CodeGen/LocalStackSlotAllocation.cpp index 811cb07628..3f79593b4e 100644 --- a/lib/CodeGen/LocalStackSlotAllocation.cpp +++ b/lib/CodeGen/LocalStackSlotAllocation.cpp @@ -74,10 +74,12 @@ FunctionPass *llvm::createLocalStackSlotAllocationPass() { bool LocalStackSlotPass::runOnMachineFunction(MachineFunction &MF) { MachineFrameInfo *MFI = MF.getFrameInfo(); + const TargetRegisterInfo *TRI = MF.getTarget().getRegisterInfo(); unsigned LocalObjectCount = MFI->getObjectIndexEnd(); - // Early exit if there are no locals to consider - if (!LocalObjectCount) + // If the target doesn't want/need this pass, or if there are no locals + // to consider, early exit. + if (!TRI->requiresVirtualBaseRegisters(MF) || LocalObjectCount == 0) return true; // Make sure we have enough space to store the local offsets. -- cgit v1.2.3-18-g5258
