From e739a48e58c41fc0d3caa24103abef9988c77cdf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Wed, 11 Apr 2012 23:12:05 +0200 Subject: [PATCH] target-cris: QOM'ify CPU MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Embed CPUCRISState as first member of QOM CRISCPU. Let CPUClass::reset() call cpu_state_reset() for now.
