[PATCH 12/22] [GDBserver] Multi-process + multi-arch: GNU/Linux CRISv32


This adjusts the GNU/Linux CRISv32 port to new interfaces.

Completely untested.

2013-05-30  Pedro Alves  <palves@redhat.com>

	* linux-cris-low.c (tdesc_crisv32): Declare.
	(cris_arch_setup): New function.
	(cris_regsets_info, cris_usrregs_info, regs_info): New globals.
	(cris_regs_info): New function.
	(the_low_target): Adjust.
	(initialize_low_arch): New function.
