ocamlprof - Man Page

The OCaml profiler


ocamlprof [ options ] filename ...


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.


-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.


Print version string and exit.


Print short version number and exit.

-help or --help

Display a short usage summary and exit.
