5501 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5502 comments and single quotes. Fixes a problem found on hpux.
5504 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5506 * aclocal.m4: Remove Make-common.in from dependencies.
5507 * (distclean): Remove targ-vals.def.
5509 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5510 into here. Makes insertion into makefiles easier. Also, change
5511 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5512 targ-map.o, and run are built. They are now built in the
5513 individual simulator directories, taking sources from ../common as
5514 necessary. This replaces the merging of libcommon.a into
5515 linsim.a, which was problematic for the WinGDB build process.
5516 * run.c: Include config.h from . instead of ../common.
5517 * Make-common.in: Remove. It's no longer necessary.
5519 Mon Dec 16 15:02:33 1996 Ian Lance Taylor <ian@cygnus.com>
5521 * Make-common.in (ALL_CLAGS): Put CFLAGS at the end.
5522 (.c.o): Put $(ALL_CFLAGS) before the file being compiled.

5532 (default_callback): Add os_error.
5534 Mon Nov 25 19:44:35 1996 Doug Evans <dje@canuck.cygnus.com>
5536 * Make-common.in (Makefile): Set CONFIG_HEADERS="".
5537 * aclocal.m4: Mark the fact that --enable-sim-bswap isn't host
5539 (SIM_AC_OUTPUT): Don't build Makefile if CONFIG_FILES="".
5541 Wed Nov 20 01:11:04 1996 Doug Evans <dje@canuck.cygnus.com>
5543 * run.c: #include ../common/config.h, tconfig.h.
5544 (myname): New static global.
5545 (main): Recognize new options -a, -c. Also recognize -h if h8/300.
5546 Only process -c ifdef SIM_HAVE_SIMCACHE.
5547 Only process -p/-s ifdef SIM_HAVE_PROFILE.
5548 Parse program name from argv[0] and use in error messages.
5549 Pass sim_args to sim_open. Pass prog_args to sim_create_inferior.
5550 Add support for incomplete h8/300 termination indicators.
5551 (usage): Make more verbose.
5552 * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5560 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
5562 * run.c (main): Don't print out anything if the signal
5563 number is zero (ie no signal).
5565 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5567 * run.c (main): Print out if the program raised a signal.
5569 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5571 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5574 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>
5576 * run.c (main): Explicitly cast malloc() parameter.

5588 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5590 * run.c (main): Removed SH specific comments, so source is
5591 generic. Also updated to only load relevant sections. Moved
5592 sim_open() to after callback attach (to match GDB).
5594 * run.1: Removed SH specific comments.
5596 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5598 * run.c (main): Always return sigrc at end.
5600 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
