5503 * (distclean): Remove targ-vals.def.
5505 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5506 into here. Makes insertion into makefiles easier. Also, change
5507 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5508 targ-map.o, and run are built. They are now built in the
5509 individual simulator directories, taking sources from ../common as
5510 necessary. This replaces the merging of libcommon.a into
5511 linsim.a, which was problematic for the WinGDB build process.
5512 * run.c: Include config.h from . instead of ../common.
5513 * Make-common.in: Remove. It's no longer necessary.
5515 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
5517 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
5518 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.
5520 Wed Dec 11 11:30:58 1996 Jim Wilson <wilson@cygnus.com>
5522 * run.c (main): Set target_byte_order before call to sim_open.
5524 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
5526 * callback.c: #include <stdlib.h>
5527 (os_error): New function.
5528 (default_callback): Add os_error.
5530 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5532 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5533 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5535 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5537 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5539 * run.c: #include ../common/config.h, tconfig.h.
5540 (myname): New static global.
5541 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5542 Only process -c ifdef SIM_HAVE_SIMCACHE.
5543 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5544 Parse program name from argv[0] and use in error messages.
5545 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5546 Add support for incomplete h8/300 termination indicators.
5547 (usage): Make more verbose.
5548 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
5549 * Makefile.in,Make-common.in,callback.c: New files.

5554 * run.c: Include stdarg.h if __STDC__.
5556 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5558 * run.c (main): Don't print out anything if the signal
5559 number is zero (ie no signal).
5561 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5563 * run.c (main): Print out if the program raised a signal.
5565 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5567 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5570 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
5572 * run.c (main): Explicitly cast malloc() parameter.
5574 Thu Sep 12 11:27:21 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5576 * run.c (sim_bfd): New global to hold the bfd pointer for the
5578 (main): Initialize sim_bfd.
5580 Fri Dec 15 16:27:49 1995 Ian Lance Taylor <ian@cygnus.com>
5582 * run.c (main): Use new bfd_big_endian macro.
5584 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5586 * run.c (main): Removed SH specific comments, so source is
5587 generic. Also updated to only load relevant sections. Moved
5588 sim_open() to after callback attach (to match GDB).
5590 * run.1: Removed SH specific comments.
5592 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5594 * run.c (main): Always return sigrc at end.
5596 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
5598 * run.c (main): Print error diagnostic and exit if bfd_openr() or
5599 bfd_check_format() fails.
5601 Thu Sep 28 15:40:36 1995 steve chamberlain <sac@slash.cygnus.com>
5603 * run.c, run.1: From sh directory.
