[LLVMdev] LowerArguments vs LowerFORMAL_ARGUMENTS

[Villmow, Micah]

What is the difference between these two functions? The header file for
TargetLowering class says that LowerArguments must be implemented, but
only the Sparc and IA64 backends implement them. X86, PowerPC and
CellSPU implement LowerFORMAL_ARGUMENTS, but I can find a
setOperationAction that states that they should be lowered. Can someone
please explain this for me?

 

Thanks,
