[Coco] Profiling emulator?

[Mark McDougall]

Hi all,

Here's a long shot. I'm looking for a Coco3 emulator that does profiling 
on emulated code; does anyone know if such a beast exists? I've pretty 
much only ever used MAME/MESS for Coco emulation...

What I need specifically is a tool that allows me to see what percentage 
of run-time is spent in each of the routines. The idea would be to run 
the software for a few minutes, and then (eg on exit) have the emulator 
display a list of subroutine calls and metrics on the total number of 
times each was called, and how many cycles in total was spent in each.

FTR I've been told that the Altirra Atari emulator has rather 
comprehensive profiling built-in.

Alternatively, and more likely, what would be a good (open source) 
candidate for me to add profiling functionality to? Ordinarily I would 
have a crack at MAME/MESS but getting that functionality accepted into 
the official build would be... an arduous task. So, what about VCC? I 
wouldn't want to go to the effort of adding the functionality and not 
have it available for other - and myself - in the future?

And I'm also open to suggestions on other means to achieve the same results?

Regards,
