struct MachineFunctionInfo
Declaration
struct MachineFunctionInfo { /* full declaration omitted */ };
Description
MachineFunctionInfo - This class can be derived from and used by targets to hold private target-specific information for each MachineFunction. Objects of type are accessed/created with MF::getInfo and destroyed when the MachineFunction is destroyed.
Declared at: llvm/include/llvm/CodeGen/MachineFunction.h:95
Method Overview
- public virtual llvm::MachineFunctionInfo * clone(llvm::BumpPtrAllocator & Allocator, llvm::MachineFunction & DestMF, const DenseMap<llvm::MachineBasicBlock *, llvm::MachineBasicBlock *> & Src2DstMBB) const
- public template <typename Ty>static Ty * create(llvm::BumpPtrAllocator & Allocator, llvm::MachineFunction & MF)
- public template <typename Ty>static Ty * create(llvm::BumpPtrAllocator & Allocator, const Ty & MFI)
- public virtual ~MachineFunctionInfo()
Methods
¶virtual llvm::MachineFunctionInfo* clone(
llvm::BumpPtrAllocator& Allocator,
llvm::MachineFunction& DestMF,
const DenseMap<llvm::MachineBasicBlock*,
llvm::MachineBasicBlock*>&
Src2DstMBB) const
virtual llvm::MachineFunctionInfo* clone(
llvm::BumpPtrAllocator& Allocator,
llvm::MachineFunction& DestMF,
const DenseMap<llvm::MachineBasicBlock*,
llvm::MachineBasicBlock*>&
Src2DstMBB) const
Description
Make a functionally equivalent copy of this MachineFunctionInfo in \p 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.

Parameters
- llvm::BumpPtrAllocator& Allocator
- llvm::MachineFunction& DestMF
- const DenseMap<llvm::MachineBasicBlock*, llvm::MachineBasicBlock*>& Src2DstMBB

template <typename Ty>
static Ty* create(
llvm::BumpPtrAllocator& Allocator,
llvm::MachineFunction& MF)
Description
Factory function: default behavior is to call new using the supplied allocator. This function can be overridden in a derive class.
