Smith * 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 * run.c (main): Always return sigrc at end. Tue Oct 10 12:03:13 1995 J.T. Conklin * run.c (main): Print error diagnostic and exit if bfd_openr() or bfd_check_format() fails.
