isDllConApp :: DynFlags -> Module -> DataCon -> [StgArg] -> Bool Source #

Does this constructor application refer to anything in a different *Windows* DLL? If so, we can't allocate it statically

stgArgType :: StgArg -> Type Source #

Type of an StgArg

Very half baked because we have lost the type arguments.

stripStgTicksTop :: (Tickish Id -> Bool) -> StgExpr -> ([Tickish Id], StgExpr) Source #

Strip ticks of a given type from an STG expression

stgCaseBndrInScope Source #

Arguments

:: AltType 
-> Bool

unarised?

-> Bool 

Given an alt type and whether the program is unarised, return whether the case binder is in scope.

Case binders of unboxed tuple or unboxed sum type always dead after the unariser has run. See Note [Post-unarisation invariants].
