Subject: [Qemu-devel] [PATCH 6/7] target-ppc: gdbstub: fix spe registers for little-endian guests
Date: Fri, 15 Jan 2016 16:00:44 +0100 [thread overview]
Message-ID: <20160115150044.17358.24887.stgit@bahia.huguette.org> (raw)
In-Reply-To: <20160115150005.17358.43294.stgit@bahia.huguette.org>
Let's reuse the ppc_maybe_bswap_register() helper, like we already do
with the general registers.
