I also wonder, if Pd gurus out there ever considered profiling
PureData.
Since there is a debug option to ./configure under linux, maybe
there could also be a profiling option. The necessary changes
to configure.in and makefile.in are very simple, such as in two
attached diffs. If they are applied, one will be able to pass
--enable-gprof to ./configure to enable gprof-ready compilation
(-pg option to gcc), and also to add another profiling option
to gcc with, for example, --enable-gprof=-ax.
I was forced to introduce one nasty (temporary?) hack of
-D_exit=exit (see my previous post), however it is used
exclusively for -enable-gprof.
