6050 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6051 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
6052 appropriate definitions of read, write, etc. Add prototype for
6055 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
6057 * Makefile.in (libcommon.a): Delete.

6080 * (distclean): Remove targ-vals.def.
6082 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in

6084 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6085 targ-map.o, and run are built. They are now built in the
6086 individual simulator directories, taking sources from ../common as
6087 necessary. This replaces the merging of libcommon.a into
6088 linsim.a, which was problematic for the WinGDB build process.
6089 * run.c: Include config.h from . instead of ../common.
6090 * Make-common.in: Remove. It's no longer necessary.

6135 * run.c (main): Don't print out anything if the signal
6136 number is zero (ie no signal).
6138 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6140 * run.c (main): Print out if the program raised a signal.
6142 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>

6161 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
6163 * run.c (main): Removed SH specific comments, so source is
6164 generic. Also updated to only load relevant sections. Moved
6165 sim_open() to after callback attach (to match GDB).
6167 * run.1: Removed SH specific comments.
6169 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6171 * run.c (main): Always return sigrc at end.
