GADT for queries with specific result type.

type 'a result = 'a
type ask = {
  1. f : 'a. 'a t -> 'a result;
}

Container for explicitly polymorphic ctx.ask function out of ctx. To be used when passing entire ctx around seems inappropriate. Use Analyses.ask_of_ctx to convert ctx to ask.

val must_be_equal : ask -> GoblintCil.exp -> GoblintCil.exp -> bool

Backwards-compatibility for former MustBeEqual query.

val may_be_equal : ask -> GoblintCil.exp -> GoblintCil.exp -> bool

Backwards-compatibility for former MayBeEqual query.

val may_be_less : ask -> GoblintCil.exp -> GoblintCil.exp -> bool

Backwards-compatibility for former MayBeLess query.
