From 399561eafa747e71202d00985206b65868142afb Mon Sep 17 00:00:00 2001 From: Hsiangkai Wang Date: Wed, 6 Mar 2013 09:39:52 +0800 Subject: gdb_server: add target_debug_reason for program exit detection Currently, there is no way to notify gdb that program has exited. Add new target_debug_reason called DBG_REASON_EXIT to notify gdb the condition has occured. If the debug reason is DBG_REASON_EXIT, gdb_server will send 'W' packet to tell gdb the process has exited.
