[PATCH 09/22] [GDBserver] Multi-process + multi-arch: GNU/Linux SH

[Pedro Alves <palves@redhat.com>]

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

Built with a cross sh-linux-gnu toolchain.  Otherwise not tested.

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

	* linux-sh-low.c (tdesc_sharch): Declare.
	(target_regsets): Rename to ...
	(sh_regsets): ... this, and make static.
	(sh_regsets_info, sh_usrregs_info, regs_info): New globals.
	(sh_regs_info, sh_arch_setup): New functions.
	(the_low_target): Adjust.
	(initialize_low_arch): New function.
