From 5b24c64188b8253e2f004191c7e8d4a799f90eaa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Sun, 7 Jul 2013 15:08:22 +0200 Subject: cpu: Introduce CPUClass::gdb_core_xml_file for GDB_CORE_XML MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the GDB_CORE_XML define in gdbstub.c with a CPUClass field. Use first_cpu for qSupported and qXfer:features:read: for now. Add a stub for xml_builtin.
