My patch optionally saves the profiling output each process in a separate file. gprof(1) can already accumulate the output from multiple files so this patch gives you the ability to profile multiple executions of a single executable. You will still need to glue together the profiling results from each executable. --=20 Peter Jeremy --XuV1QlJbYrcVoo+x Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGdtn5/opHv/APuIcRAmkyAKCboAL6jB2sRTjQluQcvc+tPlpSOACfbzet gJzXr6ckSL6Mk/PdT9nopf4= =AIBr -----END PGP SIGNATURE----- --XuV1QlJbYrcVoo+x--
