From f3659eee05793aede68b1791465fb2b0767bc1f2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Thu, 27 Jun 2013 19:09:09 +0200 Subject: [PATCH] cpu: Introduce CPUClass::memory_rw_debug() for target_memory_rw_debug() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make inline target_memory_rw_debug() always available and change its argument to CPUState. Let it check if CPUClass::memory_rw_debug provides a specialized callback and fall back to cpu_memory_rw_debug() otherwise. The only overriding implementation is for 32-bit sparc. This prepares for changing GDBState::g_cpu to CPUState.
