From a0e372f0c49ac01faeaeb73a6e8f50e8ac615f34 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andreas=20F=C3=A4rber?= Date: Fri, 28 Jun 2013 23:18:47 +0200 Subject: cpu: Introduce CPUState::gdb_num_regs and CPUClass::gdb_num_core_regs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CPUState::gdb_num_regs replaces num_g_regs. CPUClass::gdb_num_core_regs replaces NUM_CORE_REGS. Allows building gdb_register_coprocessor() for xtensa, too. As a side effect this should fix coprocessor register numbering for SMP.
