Detailed 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.

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 in llvm::AArch64FunctionInfo, llvm::SIMachineFunctionInfo, llvm::ARCFunctionInfo, llvm::ARMFunctionInfo, llvm::AVRMachineFunctionInfo, llvm::CSKYMachineFunctionInfo, llvm::HexagonMachineFunctionInfo, llvm::LanaiMachineFunctionInfo, llvm::LoongArchMachineFunctionInfo, llvm::M68kMachineFunctionInfo, llvm::MipsFunctionInfo, llvm::MSP430MachineFunctionInfo, llvm::NVPTXMachineFunctionInfo, llvm::PPCFunctionInfo, llvm::RISCVMachineFunctionInfo, llvm::SparcMachineFunctionInfo, llvm::SystemZMachineFunctionInfo, llvm::VEMachineFunctionInfo, llvm::WebAssemblyFunctionInfo, llvm::X86MachineFunctionInfo, and llvm::XCoreFunctionInfo.
