body: <p>assembly programming in Emacs how to?
  I want Emacs to do following things
  1. assembling
  2. run the just before made program inside Emacs
  3. debugging with watching flags and registers as like ollydbg or softice
  4. decompile executable file for see what assembly codes are made by c 
  but I don't know how to do this
  could somebody let me know ?</p>
