My previous message was the implementation issues involved; this one's the motivational issue. Thread_db is not, and can't/shouldn't be, available in a cross environment. We have done a lot of work to make GDB read corefiles in a cross environment; and at MontaVista we've seen a large demand for this functionality from our customers. So using thread_db with corefiles doesn't meet our (GDB developers') goals, I think. -- Daniel Jacobowitz MontaVista Software Debian GNU/Linux Developer
