4976 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4977 comments and single quotes. Fixes a problem found on hpux.
4979 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4981 * aclocal.m4: Remove Make-common.in from dependencies.
4982 * (distclean): Remove targ-vals.def.
4984 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4985 into here. Makes insertion into makefiles easier. Also, change
4986 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4987 targ-map.o, and run are built. They are now built in the
4988 individual simulator directories, taking sources from ../common as
4989 necessary. This replaces the merging of libcommon.a into
4990 linsim.a, which was problematic for the WinGDB build process.
4991 * run.c: Include config.h from . instead of ../common.
4992 * Make-common.in: Remove. It's no longer necessary.
4994 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
4996 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
4997 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.
4999 Wed Dec 11 11:30:58 1996 Jim Wilson <wilson@cygnus.com>

5003 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
5005 * callback.c: #include <stdlib.h>
5006 (os_error): New function.
5007 (default_callback): Add os_error.
5009 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5011 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5012 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5014 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5016 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5018 * run.c: #include ../common/config.h, tconfig.h.
5019 (myname): New static global.
5020 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5021 Only process -c ifdef SIM_HAVE_SIMCACHE.
5022 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5023 Parse program name from argv[0] and use in error messages.
5024 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5025 Add support for incomplete h8/300 termination indicators.
5026 (usage): Make more verbose.
5027 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5033 * run.c: Include stdarg.h if __STDC__.
5035 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5037 * run.c (main): Don't print out anything if the signal
5038 number is zero (ie no signal).
5040 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5042 * run.c (main): Print out if the program raised a signal.
5044 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5046 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5049 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
5051 * run.c (main): Explicitly cast malloc() parameter.

5063 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5065 * run.c (main): Removed SH specific comments, so source is
5066 generic. Also updated to only load relevant sections. Moved
5067 sim_open() to after callback attach (to match GDB).
5069 * run.1: Removed SH specific comments.
5071 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5073 * run.c (main): Always return sigrc at end.
5075 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>

5078 bfd_check_format() fails.
