6058 appropriate definitions of read, write, etc. Add prototype for
6061 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
6063 * Makefile.in (libcommon.a): Delete.

6090 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6091 targ-map.o, and run are built. They are now built in the
6092 individual simulator directories, taking sources from ../common as
6093 necessary. This replaces the merging of libcommon.a into
6094 linsim.a, which was problematic for the WinGDB build process.
6095 * run.c: Include config.h from . instead of ../common.
6096 * Make-common.in: Remove. It's no longer necessary.

6141 * run.c (main): Don't print out anything if the signal
6142 number is zero (ie no signal).
6144 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6146 * run.c (main): Print out if the program raised a signal.
6148 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>

6167 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
6169 * run.c (main): Removed SH specific comments, so source is
6170 generic. Also updated to only load relevant sections. Moved
6171 sim_open() to after callback attach (to match GDB).
6173 * run.1: Removed SH specific comments.
6175 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6177 * run.c (main): Always return sigrc at end.
