2581 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
2583 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
2584 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
2585 appropriate definitions of read, write, etc. Add prototype for
2588 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
2590 * Makefile.in (libcommon.a): Delete.

2617 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2618 targ-map.o, and run are built. They are now built in the
2619 individual simulator directories, taking sources from ../common as
2620 necessary. This replaces the merging of libcommon.a into
2621 linsim.a, which was problematic for the WinGDB build process.
2622 * run.c: Include config.h from . instead of ../common.
2623 * Make-common.in: Remove. It's no longer necessary.

2668 * run.c (main): Don't print out anything if the signal
2669 number is zero (ie no signal).
2671 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
2673 * run.c (main): Print out if the program raised a signal.
2675 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
2677 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.

2694 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
2696 * run.c (main): Removed SH specific comments, so source is
2697 generic. Also updated to only load relevant sections. Moved
2698 sim_open() to after callback attach (to match GDB).
2700 * run.1: Removed SH specific comments.
2702 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
2704 * run.c (main): Always return sigrc at end.
