Re: profiling XEmacs, esp. on the C level

So far, it seems that everyone's profiling on the Lisp level.
But C
level profiling could give much better results. Has anyone
successfully used Gprof or the VC++ tools for doing C-level
profiling? When i tried in the past, i got stuck; things crashed
and i couldn't get them to work. Any success stories and
instructions telling what exactly to do?
If you can compile xemacs with icc, or icpc, you can try vtune, or the
other profiling tools intel supplies (free for open source
development).
Also, since opensolaris, sun studio 10, with debugger, and, I think,
profiling tools, is also free to download (not sure about the excact
license, but opensource is ok).
There are also nice tools, I think, from hp, but I don't recall their
name. They have limited functionality on normal x86 though, and more
meant for itatium or something. They are, however, opensource, afaik.
There is no reason to limit oneself to gprof on linux, except perhaps
for ideological reasons.
Just thought I'd put this info here,
