Subject: [Qemu-devel] [PATCH 2/7] target-ppc: rename and export maybe_bswap_register()
Date: Fri, 15 Jan 2016 16:00:18 +0100 [thread overview]
Message-ID: <20160115150018.17358.82792.stgit@bahia.huguette.org> (raw)
In-Reply-To: <20160115150005.17358.43294.stgit@bahia.huguette.org>
This helper will be used to support FP, Altivec and VSX registers when
the guest is little-endian.
