5046 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5047 targ-map.o, and run are built. They are now built in the
5048 individual simulator directories, taking sources from ../common as
5049 necessary. This replaces the merging of libcommon.a into
5050 linsim.a, which was problematic for the WinGDB build process.

5098 number is zero (ie no signal).
5100 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5102 * run.c (main): Print out if the program raised a signal.
5104 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>

5123 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5125 * run.c (main): Removed SH specific comments, so source is
5126 generic. Also updated to only load relevant sections. Moved
5127 sim_open() to after callback attach (to match GDB).
5129 * run.1: Removed SH specific comments.
5131 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5133 * run.c (main): Always return sigrc at end.
