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;

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.

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.
