Member Function Documentation

◆ deleteMachineFunctionFor()

void MachineModuleInfo::deleteMachineFunctionFor ( Function & F )

Delete the MachineFunction MF and reset the link in the IR Function to Machine Function map.

When a function is not grouped with any other function, its MF gets deleted right away. When a function is grouped with other functions, its MF gets deleted when all functions in the same group have been finalized.

◆ getMachineFunction()

MachineFunction * MachineModuleInfo::getMachineFunction ( const Function & F ) const

Returns the MachineFunction associated to IR function F if there is one, otherwise nullptr.

NOTE: New pass manager clients shall not use this method to get the MachineFunction, use MachineFunctionAnalysis instead.

◆ getOrCreateMachineFunction()

MachineFunction & MachineModuleInfo::getOrCreateMachineFunction ( Function & F )

Returns the MachineFunction constructed for the IR function F.

Creates a new MachineFunction if none exists yet. NOTE: New pass manager clients shall not use this method to get the MachineFunction, use MachineFunctionAnalysis instead.
