can I debug a primitive?

Yes, I am newbie with low stuff like this. I have downloaded VMMaker and browse the class Interpreter to see the smalltalk (slang) code of the primitives I want to investigate that are primitiveStoreImageSegment and primitiveLoadImageSegment.....now, the question is, should I be able to put a self halt there and debug it? I tried but I did nothing. Is this possible ? I thought it was :(

Thanks for the help.

Mariano

Re: can I debug a primitive?

That would be nice indeed. And you can do it if you simulate the VM,
i.e., run the interpreter inside an image as Smalltalk code. To get
the interpreter working may be challenging, though. I once had a
working version and submitted some patches to Mantis. I don't think
these were integrated, though. Also note that in the debugger you just
see pointers and not objects, so even with the Smalltalk debugger it
can get complicated to debug the VM.

I do not know for now, for few years ago you could. Simply adding a
'self halt' in the VM code or pressing Cmd-. while executing would
popup a debugger.

Ok...thanks for the replies. I think right now I will "debug it" with pen and paper :)

Cheers,

Re: can I debug a primitive?

XCode, http://svn.isqueak.org/vm, and some breakpoints works as well, if you can't get it running in smalltalk :)

You only need to remove the MainWindow.xib from SqueakPureObjC targets' resources if you don't have the iPhone libs installed, then it's build and go!)

Cheers,

hahahaha. I was sure someone would say me "gdb is your friend". But not, I don't like gdb, I want smalltalk debugger :)

Anyway, thanks for the tip. It would be useful for another time or if actually I want to debug the c code.

Thank you!
