From 30ba0ee52d1519b717089782ef1caf0480a01dc3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Tue, 2 Jul 2013 17:43:21 +0200 Subject: cpu: Move cpu_copy() into linux-user MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is only used there and is deemed very fragile if not incorrect in its current memcpy() form. Moving it into linux-user will allow to move parts into target_cpu.h headers and only copy what the ABI mandates.
