Synopsis

Cmm top-level datatypes

type CmmProgram = [CmmGroup] Source #

type CmmGroup = GenCmmGroup CmmStatics CmmTopInfo CmmGraph Source #

Cmm group before SRT generation

type CmmGroupSRTs = GenCmmGroup RawCmmStatics CmmTopInfo CmmGraph Source #

Cmm group with SRTs

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 #

type CmmDecl = GenCmmDecl CmmStatics CmmTopInfo CmmGraph Source #

type CmmDeclSRTs = GenCmmDecl RawCmmStatics CmmTopInfo CmmGraph 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).
