virtual iterator llvm::TargetRegisterClass::allocation_order_begin | ( | MachineFunction & | MF | ) | const [inline, virtual] |
allocation_order_begin/end - These methods define a range of registers which specify the registers in this class that are valid to register allocate, and the preferred order to allocate them in. For example, callee saved registers should be at the end of the list, because it is cheaper to allocate caller saved registers.
These methods take a MachineFunction argument, which can be used to tune the allocatable registers based on the characteristics of the function. One simple example is that the frame pointer register can be used if frame-pointer-elimination is performed.
By default, these methods return all registers in the class.
