A good deal of example code can be found in the gdb source tree.
There is a PowerPC simulator there which can be used to run some code for
a couple of ppc CPUs (601, 603, 604, 403 and some others)
You might want to take the powerpc simulator code and see how this
interfaces with gdb.
Just build the gdb with "--target=powerpc-eabi" and in powerpc-eabi-gdb, you
can do "target sim".
You can use the normal gdb to debug the powerpc-eabi-gdb and see what
happens when you enter the simulator startup.
It would be a good basis to work from.
Best regards,
Jan
