+       * run.c (sim_bfd): New global to hold the bfd pointer for the
+       executable.
+       (main): Initialize sim_bfd.

+       * run.c (main): Removed SH specific comments, so source is
+       generic. Also updated to only load relevant sections. Moved
+       sim_open() to after callback attach (to match GDB).
