The
ocamlcp script is a front-end to
ocamlc(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
ocamlprof(1) . ocamlcp accepts the same arguments and options as
ocamlc(1) .
OPTIONS
In addition to the
ocamlc(1) options,
ocamlcp accepts the following option controlling the amount of profiling
information:
-p letters
The letters following
-p indicate which parts of the program should be profiled:
a
all options
f
function calls : a count point is set at the beginning of function bodies
i
if... then... else: count points are set in
both "then" branch and "else" branch
l
while, for loops: 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
t
try...with branches: a count point is set at the
beginning of the body of each branch
For instance, compiling with
ocamlcp -pfilm profiles function calls, if... then... else..., loops, and pattern
matching.
Calling
ocamlcp(1) without the
-p option defaults to
-p fm meaning
that only function calls and pattern matching are profiled.
