Recent CHUD?

Has anyone tried running a recent set of CHUD profiling tools against  
a recent ccl? I get interesting looking output, but no symbol values,  
which seems to be a common problem. If there someone who might be able  
to fix in with just a bit of work, or someone who could lend some  
experience and point me to the resources I'd need to fix it, that  
would be super helpful.

This is with a ccl checkout from this morning + Shark.app 4.6.0 (which  
apparently comes with XCode 3.1).

Thanks,
Thom

Re: Recent CHUD?

CHUD 4.6.0 seems to have quietly dropped support for ".spatch" files,
which had been the mechanism used to tell Shark the names of what
would otherwise be anonymous memory regions.  (Like lisp functions.)
It added support for "dSYM" files (which, if I understand correctly,
contain DWARF2 debugging info.)

I haven't installed the final XCode 3.1 yet, but in the beta versions
it worked to revert to 4.5.0 after installing XCode 3.1bwhatever.
("Worked" in this case means "worked with the CCL interface"; if
there's some sort of XCode/CHUD integration that depends on new
stuff in 4.6, I wouldn't know.)

4.5.0 is available as a free download from the ADC members site
(connect.apple.com; you need to register but don't need to pay.)

In the long term, some combination of trying to get the CHUD
developers to reinstate "spatch" file support and some exploration of
the alternatives (dSYM, whatever) seems like the right thing.  In
the short term, reinstalling 4.5 seems to work (as noted above.)

Re: Recent CHUD?

Thanks, Gary. That seems to work. The call stacks seem to be inverted  
(or maybe I'm reading them wrong), but the symbol names are there and  
this will definitely be useful. When I get enough time to put in  
serious optimization work, maybe I can take a look into the dSYM  
approach.

Thanks,
Thom
