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

Emit a data-segment data block

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

Emit a read-only data block

emitDataCon :: CLabel -> CmmInfoTable -> CostCentreStack -> [CmmLit] -> FCode () Source #

emitRtsCall :: UnitId -> FastString -> [(CmmExpr, ForeignHint)] -> Bool -> FCode () Source #

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

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

emitBarf :: String -> FCode () Source #

assignTemp :: CmmExpr -> FCode LocalReg Source #

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

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

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

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

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

tagToClosure :: Platform -> TyCon -> CmmExpr -> CmmExpr Source #

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

callerSaves :: Platform -> GlobalReg -> Bool Source #

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

callerSaveVolatileRegs :: Platform -> (CmmAGraph, CmmAGraph) Source #

get_GlobalReg_addr :: Platform -> GlobalReg -> CmmExpr Source #

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.
