◆ addLiveInAttr()

void llvm::PPCFunctionInfo::addLiveInAttr ( Register  VReg,

◆ clone()

MachineFunctionInfo * PPCFunctionInfo::clone ( BumpPtrAllocator Allocator,
MachineFunction DestMF,
const DenseMap< MachineBasicBlock *, MachineBasicBlock * > &  Src2DstMBB 
) const
overridevirtual

Make a functionally equivalent copy of this MachineFunctionInfo in MF.

This requires remapping MachineBasicBlock references from the original parent to values in the new function. Targets may assume that virtual register and frame index values are preserved in the new function.

Reimplemented from llvm::MachineFunctionInfo.

inline

MustSaveLR - This is set when the prolog/epilog inserter does its initial scan of the function.

It is true if the LR/LR8 register is ever explicitly defined/clobbered in the machine function (e.g. by calls and movpctolr, which is used in PIC generation), or if the LR stack slot is explicitly referenced by builtin_return_address.
