3092 individual simulator directories, taking sources from ../common as
3093 necessary. This replaces the merging of libcommon.a into
3094 linsim.a, which was problematic for the WinGDB build process.
3095 * run.c: Include config.h from . instead of ../common.
3096 * Make-common.in: Remove. It's no longer necessary.

3109 * callback.c: #include <stdlib.h>
3110 (os_error): New function.
3111 (default_callback): Add os_error.
3113 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
3115 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
3116 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
3118 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
3120 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
3122 * run.c: #include ../common/config.h, tconfig.h.
3123 (myname): New static global.
3124 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
3125 Only process -c ifdef SIM_HAVE_SIMCACHE.
3126 Only process -p/-s ifdef SIM_HAVE_PROFILE.
3127 Parse program name from argv[0] and use in error messages.
3128 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
3129 Add support for incomplete h8/300 termination indicators.
3130 (usage): Make more verbose.
3131 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

3142 number is zero (ie no signal).
3144 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
3146 * run.c (main): Print out if the program raised a signal.
3148 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>

3167 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
3169 * run.c (main): Removed SH specific comments, so source is
3170 generic. Also updated to only load relevant sections. Moved
3171 sim_open() to after callback attach (to match GDB).
