Hi Emacs hackers.

I have tried to understand function (debug) on elisp level, and find some
details on C level(e.g. debugger-step-after-exit).
So, I attach emacs process to gdb.

Backtrace is like:
...
#14 0x0818f78b in Ffuncall (nargs=1, args=0xbfa63a00) at eval.c:3021
#15 0x081c8d21 in Fbyte_code (bytestr=154800713, vector=166927821,
maxdepth=16)
    at bytecode.c:680
#16 0x081911b2 in Feval (form=165809550) at eval.c:2352
...

Is there any help function to display form, etc? And is there any
instruction files on hacking C files?

Thanks,
Davy
