5519 Tue Feb 11 13:46:49 1997 Michael Meissner <meissner@tiktok.cygnus.com>
5521 * callback.c: If HAVE_CONFIG_H is defined, include config.h from
5522 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5523 appropriate definitions of read, write, etc. Add prototype for
5526 Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5528 * Makefile.in (libcommon.a): Delete.

5545 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
5546 comments and single quotes. Fixes a problem found on hpux.

5551 * (distclean): Remove targ-vals.def.
5553 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5554 into here. Makes insertion into makefiles easier. Also, change
5555 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5556 targ-map.o, and run are built. They are now built in the
5557 individual simulator directories, taking sources from ../common as
5558 necessary. This replaces the merging of libcommon.a into
5559 linsim.a, which was problematic for the WinGDB build process.
5560 * run.c: Include config.h from . instead of ../common.
5561 * Make-common.in: Remove. It's no longer necessary.

5606 * run.c (main): Don't print out anything if the signal
5607 number is zero (ie no signal).
5609 Tue Oct 15 11:20:44 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5611 * run.c (main): Print out if the program raised a signal.
5613 Wed Sep 18 09:52:14 1996 Michael Meissner <meissner@tiktok.cygnus.com>
5615 * run.c (exec_bfd): Rename from sim_bfd, to use the gdb name.
5618 Tue Sep 17 11:04:50 1996 James G. Smith <jsmith@cygnus.co.uk>

5632 Wed Nov 8 15:49:49 1995 James G. Smith <jsmith@pasanda.cygnus.co.uk>
5634 * run.c (main): Removed SH specific comments, so source is
5635 generic. Also updated to only load relevant sections. Moved
5636 sim_open() to after callback attach (to match GDB).
5638 * run.1: Removed SH specific comments.
5640 Sat Oct 21 12:31:01 1995 Jim Wilson <wilson@chestnut.cygnus.com>
5642 * run.c (main): Always return sigrc at end.
5644 Tue Oct 10 12:03:13 1995 J.T. Conklin <jtc@rtl.cygnus.com>
