Jocamlcp - The JoCaml profiling compiler
jocamlcp [ jocamlcp options ] [ -p flags ] filename ...
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).
In addition to the jocamlc(1) options, jocamlcp accepts the following
option controlling the amount of profiling information:
The letters indicate which parts of the program should be
a all options
f function calls : a count point is set at the beginning of each
i if ... then ... else: count points are set in both then and else
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.
