    the Analysis library. *)

(** [verify_module m] returns [None] if the module [m] is valid, and
    [Some reason] if it is invalid. [reason] is a string containing a
    human-readable validation report. See [llvm::verifyModule]. *)

(** [verify_function f] returns [None] if the function [f] is valid, and
    [Some reason] if it is invalid. [reason] is a string containing a
    human-readable validation report. See [llvm::verifyFunction]. *)

(** [verify_module m] returns if the module [m] is valid, but prints a
    validation report to [stderr] and aborts the program if it is invalid. See
    [llvm::verifyModule]. *)

    the current function with the code for each basic block inside.
