Backend_intf.Sval really_import_approx : Simple_value_approx.t -> Simple_value_approx.tIf the given approximation is that of a symbol (Value_symbol) or an external (Value_extern), attempt to find a more informative approximation from a previously-written compilation artifact. In the native code backend, for example, this might consult a .cmx file.
val import_symbol : Symbol.t -> Simple_value_approx.tval closure_symbol : Closure_id.t -> Symbol.tThe natural size of an integer on the target architecture (cf. Arch.size_int in the native code backend).
