5550 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5552 * Makefile.in (libcommon.a): Delete.

5581 individual simulator directories, taking sources from ../common as
5582 necessary. This replaces the merging of libcommon.a into

5631 number is zero (ie no signal).
5633 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5635 * run.c (main): Print out if the program raised a signal.
5637 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>

5656 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5658 * run.c (main): Removed SH specific comments, so source is
5659 generic. Also updated to only load relevant sections. Moved
5660 sim_open() to after callback attach (to match GDB).
5662 * run.1: Removed SH specific comments.
5664 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
