Subject: [Qemu-devel] [PATCH 3/7] target-ppc: gdbstub: fix float registers for little-endian guests
Date: Fri, 15 Jan 2016 16:00:25 +0100
Message-ID: <20160115150025.17358.62077.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.
