5501 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5502 appropriate definitions of read, write, etc. Add prototype for
5505 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5507 * Makefile.in (libcommon.a): Delete.
5508 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5509 (gentmap,targ-vals.h,targ-map.c): Likewise.
5510 (run-autoconf): Delete.
5511 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
5512 (common makefile fragment): Moved back into ...
5513 * Make-common.in: Resurrect.
5514 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
5515 * configure: Regenerated.
5517 Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
5519 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
5520 (SIM_AC_OUTPUT): To here.
5522 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
5524 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5525 comments and single quotes. Fixes a problem found on hpux.
5527 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5529 * aclocal.m4: Remove Make-common.in from dependencies.
5530 * (distclean): Remove targ-vals.def.
5532 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5533 into here. Makes insertion into makefiles easier. Also, change
5534 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5535 targ-map.o, and run are built. They are now built in the
5536 individual simulator directories, taking sources from ../common as
5537 necessary. This replaces the merging of libcommon.a into
5538 linsim.a, which was problematic for the WinGDB build process.
5539 * run.c: Include config.h from . instead of ../common.
5540 * Make-common.in: Remove. It's no longer necessary.
5542 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
5544 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
5545 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.

5551 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
5553 * callback.c: #include <stdlib.h>
5554 (os_error): New function.
5555 (default_callback): Add os_error.
5557 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5559 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5560 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5562 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5564 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5566 * run.c: #include ../common/config.h, tconfig.h.
5567 (myname): New static global.
5568 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5569 Only process -c ifdef SIM_HAVE_SIMCACHE.
5570 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5571 Parse program name from argv[0] and use in error messages.
5572 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5573 Add support for incomplete h8/300 termination indicators.
5574 (usage): Make more verbose.
5575 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5583 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5585 * run.c (main): Don't print out anything if the signal
5586 number is zero (ie no signal).
5588 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5590 * run.c (main): Print out if the program raised a signal.
5592 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5594 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5597 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

5611 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5613 * run.c (main): Removed SH specific comments, so source is
5614 generic. Also updated to only load relevant sections. Moved
5615 sim_open() to after callback attach (to match GDB).
5617 * run.1: Removed SH specific comments.
5619 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5621 * run.c (main): Always return sigrc at end.
5623 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
5625 * run.c (main): Print error diagnostic and exit if bfd_openr() or
5626 bfd_check_format() fails.
