[PATCH 02/22] [GDBserver] Multi-process + multi-arch: GNU/Linux IA64

[Pedro Alves <palves@redhat.com>]

This adjusts the GNU/Linux IA64 port to new interfaces.

Previously tested on ia64-unknown-linux-gnu, local gdbserver.

2013-05-29  Pedro Alves  <palves@redhat.com>

	* linux-ia64-low.c (tdesc_ia64): Declare.
	(ia64_fetch_register): Adjust.
	(ia64_usrregs_info, regs_info): New globals.
	(ia64_regs_info): New function.
	(the_low_target): Adjust.
	(initialize_low_arch): New function.
