PATCH : H8300 Simulator File I/O Implementation

[D.Venkatasubramanian, Noida]

Hi All,

Based on my earlier mail:

http://sources.redhat.com/ml/gdb-patches/2002-12/msg00760.html

and subsequent ideas and suggestions from Kazu Hirata, I am 
submitting the modified patches.

Changes:
1) Comments included in each .S file.
2) An include directive which had unintentionally crept in last 
time has been removed.
3) A commented C statement in my earlier patch removed in 
simulator patch.

Regards,

Venky

	* compile.c (decode): Added code for some more magic traps.
	* compile.c (sim_resume): Added support for File I/O system
	calls through callback to host_system.
	System calls provided support for :
	open, read, write, lseek, close, stat, fstat
	Only basic support for stat and fstat.
