- NO,$00,$00,$00,INVALID
- ; used as base register in reference when referring to the top
- ; of the evaluation stack (offset = offset on the evaluation
- ; stack)
- R0,$01,$00,$00,evalstacktopptr
- ; for addressing locals ("stack pointer")
- R1,$01,$00,$01,localsstackptr
- ; generic fake evaluation stack register for use by the register allocator
- R2,$01,$00,$02,evalstacktop
- ; fake register, representing the local frame pointer. Used for accessing
- ; address-taken local variables on the linear stack: (localframeptr+offset).
