gdbserver, attach to stopped processes
Last modified: 2012-02-27 16:31:19 UTC
linux gdbserver doesn't know how to attach to stopped processes (while native
GDB does). It should.
On Fedora 16, running 3.2.3-2.fc16.x86_64, it seems waitpid no longer hangs after attach, if the process was stopped. So no special handling is necessary there. Tested with the attach-stopped.exp test against the native-extended-remote board. Special handling like gdb/linux-nat.c does may be still necessary for older kernels, if someone cares for those.
