4460 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4462 * Makefile.in (libcommon.a): Delete.
4463 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4464 (gentmap,targ-vals.h,targ-map.c): Likewise.
4465 (run-autoconf): Delete.
4466 * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
4467 (common makefile fragment): Moved back into ...
4468 * Make-common.in: Resurrect.
4469 * configure.in (AC_LINK_FILES): Delete, unnecessary now.
4470 * configure: Regenerated.
4472 Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
4474 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
4475 (SIM_AC_OUTPUT): To here.
4477 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
4479 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4480 comments and single quotes. Fixes a problem found on hpux.
4482 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4484 * aclocal.m4: Remove Make-common.in from dependencies.
4485 * (distclean): Remove targ-vals.def.
4487 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4488 into here. Makes insertion into makefiles easier. Also, change
4489 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4490 targ-map.o, and run are built. They are now built in the
4491 individual simulator directories, taking sources from ../common as
4492 necessary. This replaces the merging of libcommon.a into
4493 linsim.a, which was problematic for the WinGDB build process.
4494 * run.c: Include config.h from . instead of ../common.
4495 * Make-common.in: Remove. It's no longer necessary.
4497 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
4499 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
4500 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.
4502 Wed Dec 11 11:30:58 1996 Jim Wilson <wilson@cygnus.com>
4504 * run.c (main): Set target_byte_order before call to sim_open.
4506 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
4508 * callback.c: #include <stdlib.h>
4509 (os_error): New function.
4510 (default_callback): Add os_error.
4512 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
4514 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
4515 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4517 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
4519 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
4521 * run.c: #include ../common/config.h, tconfig.h.
4522 (myname): New static global.
4523 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
4524 Only process -c ifdef SIM_HAVE_SIMCACHE.
4525 Only process -p/-s ifdef SIM_HAVE_PROFILE.
4526 Parse program name from argv[0] and use in error messages.
4527 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
4528 Add support for incomplete h8/300 termination indicators.
4529 (usage): Make more verbose.
4530 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

4536 * run.c: Include stdarg.h if __STDC__.
4538 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4540 * run.c (main): Don't print out anything if the signal
4541 number is zero (ie no signal).
4543 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4545 * run.c (main): Print out if the program raised a signal.
4547 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4549 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
4552 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
4554 * run.c (main): Explicitly cast malloc() parameter.

4564 * run.c (main): Use new bfd_big_endian macro.
4566 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
4568 * run.c (main): Removed SH specific comments, so source is
4569 generic. Also updated to only load relevant sections. Moved
4570 sim_open() to after callback attach (to match GDB).
4572 * run.1: Removed SH specific comments.
4574 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
4576 * run.c (main): Always return sigrc at end.
4578 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
4580 * run.c (main): Print error diagnostic and exit if bfd_openr() or
4581 bfd_check_format() fails.
