Hi.
I have a fairly large project that is built using make. It takes a few
minutes to build, and I'm interested in where this time is going. Is
there a standard way to profile a make run? This seems like it's a
problem that should have been solved by now (as it seems that it should
be a fairly common request).
I have managed to cobble something hacky together by stracing'ing make
and then stitching the results back together, but it's not nice, slows
things down, and only gives me some information. Really, I'd like to
know wall time, cpu time and io-wait time for each sub-process / command
that make runs.
(For the avoidance of doubt, I'm not interested in profiling the actual
make executable, but rather the processes that it runs, 50% in gcc, 40%
in as, 10% in ld, etc...).
Thanks for any advice,
Mark M.
PS.
If such a feature isn't in make, would it be feasible to add it as an
option?
