## NAME

ocamlprof - The OCaml profiler

## SYNOPSIS

ocamlprof [ options ] filename ...

## DESCRIPTION

The ocamlprof command prints execution counts gathered during the execution of a OCaml program instrumented with ocamlcp (1).

It produces a source listing of the program modules given as arguments where execution counts have been inserted as comments. For instance,

ocamlprof foo.ml

prints the source code for the foo module, with comments indicating how many times the functions in this module have been called. Naturally, this information is accurate only if the source file has not been modified since the profiling execution took place.

## OPTIONS

-f \ dumpfile Specifies an alternate dump file of profiling information.

-F \ string Specifies an additional string to be output with profiling information. By default, ocamlprof (1)will annotate programs with comments of the form (* \ n \ *) where n is the counter value for a profiling point. With option -F \ s the annotation will be (* \ sn \ *)

-impl \ filename Compile the file filename as an implementation file, even if its extension is not .ml.

-intf \ filename Compile the file filename as an interface file, even if its extension is not .mli.

-version Print version string and exit.

-vnum Print short version number and exit.

-help \ or \ --helpDisplay a short usage summary and exit.
