Hmm, but why would such a board be using gdbserver-support.exp? Can you expand a little? > > Is the intention to remove noinferiorio from gdbserver-base.exp and keep > the tests with the if {[target_info exists gdb,noinferiorio]} check ? The idea was make all tests that rely on inferior io make use of $inferior_spawn_id, like interrupt.exp. My thought was that once that is done, we can either remove noinferiorio from gdbserver-base.exp or leave it, it wouldn't matter, as for gdbserver testing, would be always $inferior_spawn_id != $gdb_spawn_id. But it sounds like you have some environment that may make that troublesome. I'll need to know more about it though. Thanks, Pedro Alves
