2577 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
2579 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
2580 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
2581 appropriate definitions of read, write, etc. Add prototype for
2584 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
2586 * Makefile.in (libcommon.a): Delete.

2592 * Make-common.in: Resurrect.
2593 * configure.in (AC_LINK_FILES): Delete, unnecessary now.

2603 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
2604 comments and single quotes. Fixes a problem found on hpux.

2609 * (distclean): Remove targ-vals.def.
2611 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
2612 into here. Makes insertion into makefiles easier. Also, change
2613 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2614 targ-map.o, and run are built. They are now built in the
2615 individual simulator directories, taking sources from ../common as
2616 necessary. This replaces the merging of libcommon.a into
2617 linsim.a, which was problematic for the WinGDB build process.
2618 * run.c: Include config.h from . instead of ../common.
2619 * Make-common.in: Remove. It's no longer necessary.

2664 * run.c (main): Don't print out anything if the signal
2665 number is zero (ie no signal).
2667 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
2669 * run.c (main): Print out if the program raised a signal.
2671 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
2673 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
2676 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

2690 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
2692 * run.c (main): Removed SH specific comments, so source is
2693 generic. Also updated to only load relevant sections. Moved
2694 sim_open() to after callback attach (to match GDB).
2696 * run.1: Removed SH specific comments.
2698 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
2700 * run.c (main): Always return sigrc at end.
2702 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
2704 * run.c (main): Print error diagnostic and exit if bfd_openr() or
