No, not yet. I wasn't aware until recently, but upstream gdb has no
native (debug on the target) sh-linux support at all, and gdbserver
and gdb's remote interface are missing fdpic support which makes
symbolic debugging difficult. I'm in the process of fixing up the
abandoned & incomplete fdpic patch for gdb (thankfully the necessary
work seems to have been completed in the frv target support, but it
was done in a gratuitously frv-specific way so it needs some minor
cleanup) and hope to have something ready to use (at least
experimentally) in the next few days.
