mkStkAmodes :: VirtualSpOffset -> [(CgRep, CmmExpr)] -> FCode (VirtualSpOffset, CmmStmts) Source

mkStkAmodes is a higher-level version of mkVirtStkOffsets. It starts from the tail-call locations. It returns a single list of addressing modes for the stack locations, and therefore is in the monad. It doesn't adjust the high water mark.

pushUpdateFrame :: CmmExpr -> Code -> Code Source

emitPushUpdateFrame :: CmmExpr -> CmmExpr -> Code Source
