bool hasFP(const MachineFunction &) const override
hasFP - Return true if the specified function should have a dedicated frame pointer register.
void emitEpilogue(MachineFunction &, MachineBasicBlock &) const override
void emitPrologue(MachineFunction &, MachineBasicBlock &) const override
emitProlog/emitEpilog - These methods insert prolog and epilog code into the function.
