["D.Venkatasubramanian, Noida" <dvenkat at noida dot hcltech dot com>]

Hi,

Corrected ChangeLog.

Thanks and Regards,

Venky

2003-03-17  D.Venkatasubramanian  <dvenkat at noida dot hcltech dot com>

	* compile.c: Added #define SET_CMDLINE_LOCATION to 
	set the location of 8-bit (256 locations) where the
	Command Line arguments would be stored.
	(decode): Added a TRAP to 0xcc for Commandline 
	processing using pseudo opcode O_SYS_CMDLINE.
	(sim_resume): Added handling of O_SYS_CMDLINE Trap.
	(sim_create_inferior): Setting a pointer to 
	Commandline Args array.
	* inst.h: Added a new variable ptr_command_line for
	storing pointer to Commandline array.
