cgLit :: Literal -> FCode CmmLit

mkSimpleLit :: DynFlags -> Literal -> CmmLit

emitDataLits :: CLabel -> [CmmLit] -> FCode ()

emitRtsCallWithResult :: LocalReg -> ForeignHint -> UnitId -> FastString -> [(CmmExpr, ForeignHint)] -> Bool -> FCode ()

emitRtsCallGen :: [(LocalReg, ForeignHint)] -> CLabel -> [(CmmExpr, ForeignHint)] -> Bool -> FCode ()

assignTemp :: CmmExpr -> FCode LocalReg

newTemp :: MonadUnique m => CmmType -> m LocalReg

newUnboxedTupleRegs :: Type -> FCode ([LocalReg], [ForeignHint])

emitMultiAssign :: [LocalReg] -> [CmmExpr] -> FCode ()

emitCmmLitSwitch :: CmmExpr -> [(Literal, CmmAGraphScoped)] -> CmmAGraphScoped -> FCode ()

emitSwitch :: CmmExpr -> [(ConTagZ, CmmAGraphScoped)] -> Maybe CmmAGraphScoped -> ConTagZ -> ConTagZ -> FCode ()

tagToClosure :: DynFlags -> TyCon -> CmmExpr -> CmmExpr

mkTaggedObjectLoad :: DynFlags -> LocalReg -> LocalReg -> ByteOff -> DynTag -> CmmAGraph

callerSaves :: Platform -> GlobalReg -> Bool

Returns True if this global register is stored in a caller-saves machine register.

callerSaveVolatileRegs :: DynFlags -> (CmmAGraph, CmmAGraph)

get_GlobalReg_addr :: DynFlags -> GlobalReg -> CmmExpr

We map STG registers onto appropriate CmmExprs. Either they map to real machine registers or stored as offsets from BaseReg. Given a GlobalReg, get_GlobalReg_addr always produces the register table address for it.
