  target

Used for plugins to register custom Sail targets/backends.

register_target ~name:"foo" action will create an option -foo, that will run the provided action on the Sail abstract syntax tree after performing common frontend processing.

The various optional arguments can be used to further control the behavior of the target:

parameter ?flag
A custom flag. By default it will use the name parameter

parameter ?description
A custom description for the command line flag

parameter ?options
Additional options for the Sail executable

parameter ?pre_parse_hook
A function to call right at the start, before parsing

parameter ?pre_rewrites_hook
A function to call before doing any rewrites

parameter ?rewrites
A sequence of Sail to Sail rewrite passes for the target

parameter ?asserts_termination
Whether termination measures are enforced by assertions in the target

val get_the_target : unit -> target option

val get : name:string -> target option

val extract_options : unit -> (Arg.key * Arg.spec * Arg.doc) list

Used internally to dynamically update the option list when loading plugins
