From 7ca8b9c0dafd1cb36289aa4c92c7beae7adcd34f Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 24 May 2010 14:32:54 -0700 Subject: frv: extend gdbstub to support more features of gdb Extend gdbstub to support more features of gdb remote protocol to keep gdb-7 and emacs gud mode happy: (*) The D command. Detach debugger. (*) The H command. Handle setting the target thread by ignoring it. (*) The qAttached command. Indicate we 'attached' to an existing process. (*) The qC command. Indicate that the current thread ID is 0. (*) The qOffsets command. Indicate that no relocation has been done. (*) The qSymbol:: command. Indicate that we're not interested in looking up any symbol addresses. (*) The qSupported command. Indicate the maximum packet size and the fact that reverse step and continue aren't supported. (*) The vCont? command. Indicate that we don't support any of its variants. Also make it possible to trace the commands and replies without tracing the individual character I/O.
