Stop[e] = e

Fields

  • OutType

    Type of the hole

  • CallCtxt

    Tells if there is something interesting about the syntactic context, and hence the inliner should be a bit keener (see interestingCallContext) Specifically: This is an argument of a function that has RULES Inlining the call might allow the rule to fire Never ValAppCxt (use ApplyToVal instead) or CaseCtxt (use Select instead)

  • SubDemand

    The evaluation context of e. Tells how e is evaluated. This fuels eta-expansion or eta-reduction without looking at lambda bodies, for example.

    See Note [Eta reduction based on evaluation context] The evaluation context for other SimplConts can be reconstructed with contEvalContext
