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?<o:p></o:p></span></font></p>
