PSIM, PowerPC, GDB

[Tony Barrett]

I'm new to both the GNU and PowerPC worlds.  I'd like to use the PowerPC
simulator (PSIM) with GDB so I can bring some software development work home
without bringing an eval board too.  I do, however, have an axiom
cme0555/pb0565 eval board at work that I'd like to use with gdb.

I've done the builds for PSIM and I've got powerpc-unknown_eabi-run.exe and
powerpc-unknown-eabi-gdb.exe.

My immediate objective is to write my own startup file in assembly then move
on to some c coding.

-Can PSIM be used with an assembly program?
-What formats does PSIM take for input files?
-How do I make those files?  With gld?
-What formats does gdb take for input files/how do I make them?

Thanks in advance for any tips.
