3973 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
3975 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
3976 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
3977 appropriate definitions of read, write, etc. Add prototype for
3980 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
3982 * Makefile.in (libcommon.a): Delete.
3983 (callback.o,targ-map.o): Delete, moved to Make-common.in.
3984 (gentmap,targ-vals.h,targ-map.c): Likewise.
3985 (run-autoconf): Delete.
3986 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
3987 (common makefile fragment): Moved back into ...
3988 * Make-common.in: Resurrect.
3989 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
3990 * configure: Regenerated.
3992 Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
3994 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
3995 (SIM_AC_OUTPUT): To here.
3997 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
3999 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4000 comments and single quotes. Fixes a problem found on hpux.
4002 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4004 * aclocal.m4: Remove Make-common.in from dependencies.
4005 * (distclean): Remove targ-vals.def.
4007 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4008 into here. Makes insertion into makefiles easier. Also, change
4009 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4010 targ-map.o, and run are built. They are now built in the
4011 individual simulator directories, taking sources from ../common as
4012 necessary. This replaces the merging of libcommon.a into
4013 linsim.a, which was problematic for the WinGDB build process.
4014 * run.c: Include config.h from . instead of ../common.
4015 * Make-common.in: Remove. It's no longer necessary.
4017 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
4019 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
4020 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.

4026 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
4028 * callback.c: #include <stdlib.h>
4029 (os_error): New function.
4030 (default_callback): Add os_error.
4032 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
4034 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
4035 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4037 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
4039 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
4041 * run.c: #include ../common/config.h, tconfig.h.
4042 (myname): New static global.
4043 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
4044 Only process -c ifdef SIM_HAVE_SIMCACHE.
4045 Only process -p/-s ifdef SIM_HAVE_PROFILE.
4046 Parse program name from argv[0] and use in error messages.
4047 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
4048 Add support for incomplete h8/300 termination indicators.
4049 (usage): Make more verbose.
4050 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

4056 * run.c: Include stdarg.h if __STDC__.
4058 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4060 * run.c (main): Don't print out anything if the signal
4061 number is zero (ie no signal).
4063 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4065 * run.c (main): Print out if the program raised a signal.
4067 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4069 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
4072 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

4086 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
4088 * run.c (main): Removed SH specific comments, so source is
4089 generic. Also updated to only load relevant sections. Moved
4090 sim_open() to after callback attach (to match GDB).
4092 * run.1: Removed SH specific comments.
4094 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
4096 * run.c (main): Always return sigrc at end.
4098 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
4100 * run.c (main): Print error diagnostic and exit if bfd_openr() or
4101 bfd_check_format() fails.
