- From: Pedro Alves <palves at redhat dot com>
- To: gdb-patches at sourceware dot org
- Date: Wed, 11 Apr 2012 00:48:48 +0100
- Subject: [PATCH 10/20] Multi-process + multiarch: GDBserver: GNU/Linux SH
- References: <20120410234741.526.59368.stgit@brno.lan>
This adjusts the GNU/Linux SH port to new interfaces.
Built with a cross sh-linux-gnu toolchain. Otherwise not tested.
2012-04-10 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.
