4459 * aclocal.m4 (SIM_AC_COMMON): Move COMMON_MAKEFILE_FRAG from here.
4460 (SIM_AC_OUTPUT): To here.
4462 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
4464 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4465 comments and single quotes. Fixes a problem found on hpux.
4467 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4469 * aclocal.m4: Remove Make-common.in from dependencies.
4470 * (distclean): Remove targ-vals.def.
4472 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4473 into here. Makes insertion into makefiles easier. Also, change
4474 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4475 targ-map.o, and run are built. They are now built in the
4476 individual simulator directories, taking sources from ../common as
4477 necessary. This replaces the merging of libcommon.a into
4478 linsim.a, which was problematic for the WinGDB build process.
4479 * run.c: Include config.h from . instead of ../common.
4480 * Make-common.in: Remove. It's no longer necessary.
4482 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
4484 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
4485 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.
4487 Wed Dec 11 11:30:58 1996 Jim Wilson <wilson@cygnus.com>
4489 * run.c (main): Set target_byte_order before call to sim_open.
4491 Sun Dec 8 18:22:06 1996 Doug Evans <dje@canuck.cygnus.com>
4493 * callback.c: #include <stdlib.h>
4494 (os_error): New function.
4495 (default_callback): Add os_error.
4497 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
4499 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
4500 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
4502 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
4504 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
4506 * run.c: #include ../common/config.h, tconfig.h.
4507 (myname): New static global.
4508 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
4509 Only process -c ifdef SIM_HAVE_SIMCACHE.
4510 Only process -p/-s ifdef SIM_HAVE_PROFILE.
4511 Parse program name from argv[0] and use in error messages.
4512 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
4513 Add support for incomplete h8/300 termination indicators.
4514 (usage): Make more verbose.
4515 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

4521 * run.c: Include stdarg.h if __STDC__.
4523 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4525 * run.c (main): Don't print out anything if the signal
4526 number is zero (ie no signal).
4528 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4530 * run.c (main): Print out if the program raised a signal.
4532 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4534 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
4537 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
4539 * run.c (main): Explicitly cast malloc() parameter.
4541 Thu Sep 12 11:27:21 1996 Michael Meissner <meissner@tiktok.cygnus.com>
4543 * run.c (sim_bfd): New global to hold the bfd pointer for the
4545 (main): Initialize sim_bfd.
4547 Fri Dec 15 16:27:49 1995 Ian Lance Taylor <ian@cygnus.com>
4549 * run.c (main): Use new bfd_big_endian macro.
4551 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
4553 * run.c (main): Removed SH specific comments, so source is
4554 generic. Also updated to only load relevant sections. Moved
4555 sim_open() to after callback attach (to match GDB).
4557 * run.1: Removed SH specific comments.
4559 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
4561 * run.c (main): Always return sigrc at end.
4563 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
4565 * run.c (main): Print error diagnostic and exit if bfd_openr() or
4566 bfd_check_format() fails.
