4980 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
4981 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
4982 appropriate definitions of read, write, etc. Add prototype for
4985 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4987 * Makefile.in (libcommon.a): Delete.
4988 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4989 (gentmap,targ-vals.h,targ-map.c): Likewise.
4990 (run-autoconf): Delete.
4991 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
4992 (common makefile fragment): Moved back into ...
4993 * Make-common.in: Resurrect.
4994 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
4995 * configure: Regenerated.

4999 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
5000 (SIM_AC_OUTPUT): To here.

5004 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5005 comments and single quotes. Fixes a problem found on hpux.
5007 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5009 * aclocal.m4: Remove Make-common.in from dependencies.
5010 * (distclean): Remove targ-vals.def.
5012 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5013 into here. Makes insertion into makefiles easier. Also, change
5014 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5015 targ-map.o, and run are built. They are now built in the
5016 individual simulator directories, taking sources from ../common as
5017 necessary. This replaces the merging of libcommon.a into
5018 linsim.a, which was problematic for the WinGDB build process.
5019 * run.c: Include config.h from . instead of ../common.
5020 * Make-common.in: Remove. It's no longer necessary.
5022 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
5024 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.

5033 * callback.c: #include <stdlib.h>
5034 (os_error): New function.
5035 (default_callback): Add os_error.
5037 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5039 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5040 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5042 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5044 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5046 * run.c: #include ../common/config.h, tconfig.h.
5047 (myname): New static global.
5048 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5049 Only process -c ifdef SIM_HAVE_SIMCACHE.
5050 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5051 Parse program name from argv[0] and use in error messages.
5052 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5053 Add support for incomplete h8/300 termination indicators.
5054 (usage): Make more verbose.

5063 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5065 * run.c (main): Don't print out anything if the signal
5066 number is zero (ie no signal).
5068 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5070 * run.c (main): Print out if the program raised a signal.
5072 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5074 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5077 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

5091 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5093 * run.c (main): Removed SH specific comments, so source is
5094 generic. Also updated to only load relevant sections. Moved
5095 sim_open() to after callback attach (to match GDB).
5097 * run.1: Removed SH specific comments.
5099 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5101 * run.c (main): Always return sigrc at end.
5103 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
5105 * run.c (main): Print error diagnostic and exit if bfd_openr() or
5106 bfd_check_format() fails.
