Description

Unfolding creation

Synopsis

Documentation

noUnfolding :: Unfolding Source #

There is no known Unfolding

mkInlineUnfolding :: SimpleOpts -> CoreExpr -> Unfolding Source #

Make an unfolding that may be used unsaturated (ug_unsat_ok = unSaturatedOk) and that is reported as having its manifest arity (the number of outer lambdas applications will resolve before doing any work).

mkInlineUnfoldingWithArity :: Arity -> SimpleOpts -> CoreExpr -> Unfolding Source #

Make an unfolding that will be used once the RHS has been saturated to the given arity.

mkCompulsoryUnfolding :: SimpleOpts -> CoreExpr -> Unfolding Source #

Used for things that absolutely must be unfolded

mkCompulsoryUnfolding' :: CoreExpr -> Unfolding Source #

Same as mkCompulsoryUnfolding but no simple optimiser pass is performed on the unfolding.

certainlyWillInline :: UnfoldingOpts -> IdInfo -> CoreExpr -> Maybe Unfolding Source #

Sees if the unfolding is pretty certain to inline. If so, return a *stable* unfolding for it, that will always inline. The CoreExpr is the WW'd and simplified RHS. In contrast, the unfolding template might not have been WW'd yet.
