Right, so the simulator interface would go into include/gdb/sim-sh.h .

Fri May 10 14:58:33 2002  J"orn Rennecke <joern.rennecke@superh.com>

        * sim-sh.h: New file, from include/sim-sh64.h.  Added
        SH1-SH4 / SH-DSP register numbers, moved SH5 register numbers,
        added full set of control registers.
