Documentation
emitCall :: (Convention, Convention) -> CmmExpr -> [CmmExpr] -> FCode ReturnKind Source #
emitCall conv fun args makes a call to the entry-code of fun,
using the call/return convention conv, passing args, and
returning the results to the current sequel.
emitReturn :: [CmmExpr] -> FCode ReturnKind Source #
Return multiple values to the sequel
If the sequel is Return
return (x,y)
If the sequel is AssignTo [p,q]
p=x; q=y;
adjustHpBackwards :: FCode () Source #
emitClosureProcAndInfoTable :: Bool -> Id -> LambdaFormInfo -> CmmInfoTable -> [NonVoid Id] -> ((Int, LocalReg, [LocalReg]) -> FCode ()) -> FCode () Source #
emitClosureAndInfoTable :: CmmInfoTable -> Convention -> [LocalReg] -> FCode () -> FCode () Source #
directCall :: Convention -> CLabel -> RepArity -> [StgArg] -> FCode ReturnKind Source #
data ClosureHeader Source #
Used to tell the various mkVirtHeapOffsets functions what kind
of header the object has. This will be accounted for in the
offsets of the fields returned.

mkVirtHeapOffsets :: DynFlags -> ClosureHeader -> [NonVoid (PrimRep, a)] -> (WordOff, WordOff, [(NonVoid a, ByteOff)]) Source #
mkVirtHeapOffsetsWithPadding :: DynFlags -> ClosureHeader -> [NonVoid (PrimRep, a)] -> (WordOff, WordOff, [FieldOffOrPadding a]) Source #
mkVirtConstrOffsets :: DynFlags -> [NonVoid (PrimRep, a)] -> (WordOff, WordOff, [(NonVoid a, ByteOff)]) Source #
Just like mkVirtHeapOffsets, but for constructors
mkVirtConstrSizes :: DynFlags -> [NonVoid PrimRep] -> (WordOff, WordOff) Source #
Just like mkVirtConstrOffsets, but used when we don't have the actual arguments. Useful when e.g. generating info tables; we just need to know sizes of pointer and non-pointer fields.
