I'm provisionally convinced having the user's machine run the profiling is a bad idea for most applications. I've fought mplayer and got some valid profile data from it, but it wasn't easy. This means any implementation must centre around common CFLAGS and maintaining a cache of profile data for applications on a server somewhere. Thanks, C.Davies -- gentoo-dev@gentoo.org mailing list
