type t =| Ok of Reg_with_debug_info.Set.t| Unreachable
val canonicalise : t -> tReturn a subset of the given availability set which contains no registers that are not associated with debug info (and holding values of non-persistent identifiers); and where no two registers share the same location.
val equal : t -> t -> boolval print : print_reg:(Stdlib.Format.formatter -> Reg.t -> unit) -> Stdlib.Format.formatter -> t -> unitFor debugging purposes only.
