Debugging tool to complete gcc and gdb on OS X

We are porting a compiler to OS X (poplog compiler) and have to deal
with a lot of assembly to trace and debug.

We can trace the execution with gdb of the assembly code generated by
gcc with the -g option, but can't see the content of registries as we
do so. Is there any way that we can do that (God I miss MacsBug)? Any
other tool?

Thank you

Of course you can do that. Have a look at the GDB docs - it's listed
under "Examining Data/Registers".

Have a look at this TechNote from Apple - "GDB for MacsBug Veterans".
