Thanks David,
gdb uses gregset structure, could you please
provide a link in gdb source, because we 
need something like gdb core analysis.

Thanks and Regards
Deepak

Deepak,

The format is "documented" in the Linux source code (see
http://linux.bkbits.net:8080/linux-2.5/anno/arch/ia64/kernel/process.c@1.50
for example).  The comment in that file says:

	/*
	 * coredump format:
	 *	r0-r31
	 *	NaT bits (for r0-r31; bit N == 1 iff rN is a NaT)
	 *	predicate registers (p0-p63)
	 *	b0-b7
	 *	ip cfm user-mask
	 *	ar.rsc ar.bsp ar.bspstore ar.rnat
	 *	ar.ccv ar.unat ar.fpsr ar.pfs ar.lc ar.ec
	 */

Hope this helps,

	--david
