5511 a pointer into the middle of a host word.
5512 * sim-endian.h (MS2W_4, LS2W_4): Use this function.
5514 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
5516 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
5517 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5518 appropriate definitions of read, write, etc. Add prototype for
5521 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5523 * Makefile.in (libcommon.a): Delete.
5524 (callback.o,targ-map.o): Delete, moved to Make-common.in.

5528 (common makefile fragment): Moved back into ...
5529 * Make-common.in: Resurrect.
5530 * configure.in (AC_LINK_FILES): Delete, unnecessary now.

5540 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5541 comments and single quotes. Fixes a problem found on hpux.
5543 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)

5546 * (distclean): Remove targ-vals.def.
5548 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5549 into here. Makes insertion into makefiles easier. Also, change
5550 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5551 targ-map.o, and run are built. They are now built in the
5552 individual simulator directories, taking sources from ../common as
5553 necessary. This replaces the merging of libcommon.a into
5554 linsim.a, which was problematic for the WinGDB build process.
5555 * run.c: Include config.h from . instead of ../common.
5556 * Make-common.in: Remove. It's no longer necessary.

5587 Parse program name from argv[0] and use in error messages.
5588 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5589 Add support for incomplete h8/300 termination indicators.

5601 * run.c (main): Don't print out anything if the signal
5602 number is zero (ie no signal).
5604 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5606 * run.c (main): Print out if the program raised a signal.
5608 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5610 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5613 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

5627 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5629 * run.c (main): Removed SH specific comments, so source is
5630 generic. Also updated to only load relevant sections. Moved
5631 sim_open() to after callback attach (to match GDB).
5633 * run.1: Removed SH specific comments.
5635 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5637 * run.c (main): Always return sigrc at end.
5639 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
5641 * run.c (main): Print error diagnostic and exit if bfd_openr() or
