Extending CIL with external features

type t = {
  1. mutable fd_enabled : bool;
    (*

    The enable flag. Set to default value

    *)
  2. fd_name : string;
    (*

    This is used to construct an option "--doxxx" and "--dontxxx" that * enable and disable the feature

    *)
  3. fd_description : string;
    (*

    A longer name that can be used to document the new options

    *)
  4. fd_extraopt : (string * Arg.spec * string) list;
    (*

    Additional command line options. The description strings should usually start with a space for Arg.align to print the --help nicely.

    *)
  5. fd_doit : Cil.file -> unit;
    (*

    This performs the transformation

    *)
  6. fd_post_check : bool;
    (*

    Whether to perform a CIL consistency checking after this stage, if * checking is enabled (--check is passed to cilly). Set this to true if * your feature makes any changes for the program.

    *)
}
