val reset : unit -> unit

erase all recorded times

val get : compiler_pass -> float option

returns the runtime in seconds of a completed pass

val time_call : compiler_pass -> (unit -> 'a) -> 'a

time_call pass f calls f and records its runtime.

val time : compiler_pass -> ('a -> 'b) -> 'a -> 'b

time pass f arg records the runtime of f arg

val accumulate_time : compiler_pass -> ('a -> 'b) -> 'a -> 'b

Like time for passes that can run multiple times

val print : Format.formatter -> unit

Prints all recorded timings to the formatter.
