6039 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
6041 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
6042 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
6043 appropriate definitions of read, write, etc. Add prototype for
6046 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
6048 * Makefile.in (libcommon.a): Delete.

6065 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
6066 comments and single quotes. Fixes a problem found on hpux.

6071 * (distclean): Remove targ-vals.def.
6073 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
6074 into here. Makes insertion into makefiles easier. Also, change
6075 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6076 targ-map.o, and run are built. They are now built in the
6077 individual simulator directories, taking sources from ../common as
6078 necessary. This replaces the merging of libcommon.a into
6079 linsim.a, which was problematic for the WinGDB build process.
6080 * run.c: Include config.h from . instead of ../common.
6081 * Make-common.in: Remove. It's no longer necessary.

6112 Parse program name from argv[0] and use in error messages.
6113 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
6114 Add support for incomplete h8/300 termination indicators.

6126 * run.c (main): Don't print out anything if the signal
6127 number is zero (ie no signal).
6129 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6131 * run.c (main): Print out if the program raised a signal.
6133 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
6135 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.

6152 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
6154 * run.c (main): Removed SH specific comments, so source is
6155 generic. Also updated to only load relevant sections. Moved
6156 sim_open() to after callback attach (to match GDB).
6158 * run.1: Removed SH specific comments.
6160 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
6162 * run.c (main): Always return sigrc at end.
6164 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
