NAME
Jocamlcp - The JoCaml profiling compiler
SYNOPSIS
jocamlcp [ jocamlcp options ] [ -p flags ] filename ...
DESCRIPTION
The jocamlcp command is a front-end to jocamlc(1) that instruments the
source code, adding code to record how many times functions are called,
branches of conditionals are taken, ... Execution of instrumented code
produces an execution profile in the file ocamlprof.dump, which can be
read using jocamlprof(1).
jocamlcp accepts the same arguments and options as jocamlc(1).
OPTIONS
In addition to the jocamlc(1) options, jocamlcp accepts the following
option controlling the amount of profiling information:
-p letters
The letters indicate which parts of the program should be
profiled:
a all options
f function calls : a count point is set at the beginning of each
function body
i if ... then ... else: count points are set in both then and else
branches
l 0loops: a count point is set at the beginning of the loop body
m match branches: a count point is set at the beginning of the
body of each branch of a pattern-matching
t try ... with branches: a count point is set at the beginning of
the body of each branch of an exception catcher
For instance, compiling with jocamlcp -pfilm profiles function calls,
if ... then ... else ..., loops, and pattern matching.
Calling jocamlcp(1) without the -p option defaults to -p fm meaning
that only function calls and pattern matching are profiled.
Note: due to the implementation of streams and stream patterns as
syntactic sugar, it is hard to predict what parts of stream expressions
and patterns will be profiled by a given flag. To profile a program
with streams, we recommend using jocamlcp -p a.
