Yes, this works with the simulator. I'm preparing to submit Blackfin GDB
port to the upstream.

to recognize its "syscall" sequence. If the simulator is sitting on
RAISE 0,
then it won't work anymore.

This patch replaces "RAISE 0;" with "EXCPT 0;" for syscall in Blackfin
libgloss. The syscall mechanism in libgloss is used for simulator and
hardware board. "RAISE 0" is OK for simulator, but cannot be used for
hardware board. Using a valid instruction will ensure predictable
behavior of application on hardware board although currently there
is no
non-trivial implementation of syscall for hardware board. Please review
and commit. Thanks.
