newtype GenCmm d h g

Constructors Cmm [GenCmmTop d h g] Instances (Outputable d, Outputable info, Outputable g) => Outputable (GenCmm d info g)

type Cmm = GenCmm CmmStatic CmmInfo (ListGraph CmmStmt)

Cmm with the info table as a data type

type RawCmm = GenCmm CmmStatic [CmmStatic] (ListGraph CmmStmt)

Cmm with the info tables converted to a list of CmmStatic

data GenCmmTop d h g

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 CmmFormalsWithoutKinds g CmmData Section [d] Instances (Outputable d, Outputable info, Outputable i) => Outputable (GenCmmTop d info i)

type CmmTop = GenCmmTop CmmStatic CmmInfo (ListGraph CmmStmt)

type RawCmmTop = GenCmmTop CmmStatic [CmmStatic] (ListGraph CmmStmt)

newtype ListGraph i

A control-flow graph represented as a list of extended basic blocks. Constructors ListGraph [GenBasicBlock i] Code, may be empty. The first block is the entry point. The order is otherwise initially unimportant, but at some point the code gen will fix the order. Instances Outputable instr => Outputable (ListGraph instr)
