Thu Sep 12 11:27:21 1996 Michael Meissner <meissner@tiktok.cygnus.com>
* run.c (sim_bfd): New global to hold the bfd pointer for the
executable.
(main): Initialize sim_bfd.
Fri Dec 15 16:27:49 1995 Ian Lance Taylor <ian@cygnus.com>
* run.c (main): Use new bfd_big_endian macro.
Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
* 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).
* run.1: Removed SH specific comments.
Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
* run.c (main): Always return sigrc at end.
