noExtFieldSilent :: NoExtFieldSilent Source #

Used when constructing a term with an unused extension point that should not appear in pretty-printed output at all.

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) -> GenStgExpr p -> ([Tickish Id], GenStgExpr p) Source #

Strip ticks of a given type from an STG expression.

stripStgTicksTopE :: (Tickish Id -> Bool) -> GenStgExpr p -> GenStgExpr p Source #

Strip ticks of a given type from an STG expression returning only the 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].

data StgPprOpts Source #

STG pretty-printing options

Constructors

StgPprOpts 

Fields

initStgPprOpts :: DynFlags -> StgPprOpts Source #

Initialize STG pretty-printing options from DynFlags

panicStgPprOpts :: StgPprOpts Source #

STG pretty-printing options used for panic messages
