X-Received-From: 2001:41c9:1:41f::167 Subject: [Qemu-devel] [PATCH v2 5/7] target/ppc: improve avr64_offset() and use it to simplify get_avr64()/set_avr64() X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" By using the VsrD macro in avr64_offset() the same offset calculation can be used regardless of the host endian. This allows get_avr64() and set_avr64()= to be simplified accordingly.
