GHC.Cmm

Synopsis

Cmm top-level datatypes

type CmmGroup = GenCmmGroup CmmStatics CmmTopInfo CmmGraph Source #

Cmm group before SRT generation

type RawCmmGroup = GenCmmGroup RawCmmStatics (LabelMap RawCmmStatics) CmmGraph Source #

Raw cmm group (TODO (osa): not sure what that means)

type GenCmmGroup d h g = [GenCmmDecl d h g] Source #

data GenCmmDecl d h g Source #

A top-level chunk, abstracted over the type of the contents of the basic blocks (Cmm or instructions are the likely instantiations).

Constructors

CmmProc h CLabel [GlobalReg] g
