4977 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4978 comments and single quotes. Fixes a problem found on hpux.
4980 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4982 * aclocal.m4: Remove Make-common.in from dependencies.
4983 * (distclean): Remove targ-vals.def.
4985 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4986 into here. Makes insertion into makefiles easier. Also, change
4987 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4988 targ-map.o, and run are built. They are now built in the
4989 individual simulator directories, taking sources from ../common as
4990 necessary. This replaces the merging of libcommon.a into
4991 linsim.a, which was problematic for the WinGDB build process.
4992 * run.c: Include config.h from . instead of ../common.
4993 * Make-common.in: Remove. It's no longer necessary.
4995 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
4997 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
4998 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.

5004 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
5006 * callback.c: #include <stdlib.h>
5007 (os_error): New function.
5008 (default_callback): Add os_error.
5010 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5012 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5013 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5015 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5017 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5019 * run.c: #include ../common/config.h, tconfig.h.
5020 (myname): New static global.
5021 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5022 Only process -c ifdef SIM_HAVE_SIMCACHE.
5023 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5024 Parse program name from argv[0] and use in error messages.
5025 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5026 Add support for incomplete h8/300 termination indicators.
5027 (usage): Make more verbose.
5028 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5036 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5038 * run.c (main): Don't print out anything if the signal
5039 number is zero (ie no signal).
5041 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5043 * run.c (main): Print out if the program raised a signal.
5045 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5047 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5050 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
5052 * run.c (main): Explicitly cast malloc() parameter.

5064 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5066 * run.c (main): Removed SH specific comments, so source is
5067 generic. Also updated to only load relevant sections. Moved
5068 sim_open() to after callback attach (to match GDB).
5070 * run.1: Removed SH specific comments.
5072 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5074 * run.c (main): Always return sigrc at end.
5076 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
