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

Emit a data-segment data block

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

Emit a read-only data block

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

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

assignTemp :: CmmExpr -> FCode LocalReg

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

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

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

tagToClosure :: Platform -> TyCon -> CmmExpr -> CmmExpr

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

callerSaves :: Platform -> GlobalReg -> Bool

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

callerSaveVolatileRegs :: Platform -> (CmmAGraph, CmmAGraph)

get_GlobalReg_addr :: Platform -> 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.
