Help with porting GDB

[Howard Wilkinson]

I'm trying to port GDb 3.5 to the SONY News OS4.0 and am having major
problems reading the registers of the user program at the trap points.

I'm getting register contents which looks like the kernel has overwritten
the registers and cannot work out where to go and find the right info.

Can anyone point me at an expert or a source location that might help.

Its annoying, but I'm sure I've fixed this problem elsewhere before
and cannot remember how.

Howard.
