6028 a pointer into the middle of a host word.
6029 * sim-endian.h (MS2W_4, LS2W_4): Use this function.
6031 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
6033 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6034 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
6035 appropriate definitions of read, write, etc. Add prototype for
6038 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
6040 * Makefile.in (libcommon.a): Delete.
6041 (callback.o,targ-map.o): Delete, moved to Make-common.in.

6045 (common makefile fragment): Moved back into ...
6046 * Make-common.in: Resurrect.
6047 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
6048 * configure: Regenerated.

6057 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
6058 comments and single quotes. Fixes a problem found on hpux.
6060 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
6062 * aclocal.m4: Remove Make-common.in from dependencies.
6063 * (distclean): Remove targ-vals.def.
6065 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
6066 into here. Makes insertion into makefiles easier. Also, change
6067 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6068 targ-map.o, and run are built. They are now built in the
6069 individual simulator directories, taking sources from ../common as
6070 necessary. This replaces the merging of libcommon.a into
6071 linsim.a, which was problematic for the WinGDB build process.
6072 * run.c: Include config.h from . instead of ../common.
6073 * Make-common.in: Remove. It's no longer necessary.

6087 (os_error): New function.
6088 (default_callback): Add os_error.
6090 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
6092 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
6093 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
6095 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
6097 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
6099 * run.c: #include ../common/config.h, tconfig.h.
6100 (myname): New static global.
6101 (main): Recognize new options -a, -c. Also recognize -h if h8/300.

6103 Only process -p/-s ifdef SIM_HAVE_PROFILE.
6104 Parse program name from argv[0] and use in error messages.
6105 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
6106 Add support for incomplete h8/300 termination indicators.
6107 (usage): Make more verbose.

6118 * run.c (main): Don't print out anything if the signal
6119 number is zero (ie no signal).
6121 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6123 * run.c (main): Print out if the program raised a signal.
6125 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6127 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
6130 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

6144 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
6146 * run.c (main): Removed SH specific comments, so source is
6147 generic. Also updated to only load relevant sections. Moved
6148 sim_open() to after callback attach (to match GDB).
6150 * run.1: Removed SH specific comments.
6152 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6154 * run.c (main): Always return sigrc at end.
6156 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
6158 * run.c (main): Print error diagnostic and exit if bfd_openr() or
6159 bfd_check_format() fails.
