However, printing of all segment registers is currently broken.
Don't print "last exception: " before the FPU opcode and pc, etc. The

Gary Jennejohn, too studly for his own good, has finally come through with
the new, improved gdb 4.13. This gdb features:
o kgdb support - if this works (and I urge folks to test it), we can
finally purge the old and hateful version of kgdb from our source
tree.
o attach/detach support. See comments in README.FreeBSD for more
details.
o Well, it's newer. Our previous version was 4.11.
Comments and flames to gj, of course! :-)
Thanks, Gary. Much appreciated. The previous state of gdb/kgdb has been a
thorn in all of our sides for some time..

GCC-2.6.1 COMES TO FREEBSD-current
----------------------------------
Everybody needs to 'make world'.
Oakland, Nov 2nd 1994. In a surprise move this sunny afternoon, the release-
engineer for the slightly delayed FreeBSD-2.0, Poul-Henning Kamp (28),
decided to pull in the new version 2.6.1 of the GNU C-compiler.
The new version of the compiler was release today at noon, and hardly 9
hours later it was committed into the FreeBSD-current source-repository.
"It's is simply because we have had too much trouble with the version 2.6.0
of the compiler" Poul-Henning told the FreeBSD-Gazette, "we took a gamble
when we decided to use that as our compiler for the 2.0 release, but it
seems to pay of in the end now" he concludes.
The move has not been discussed on the "core" list at all, and will come as
a surprise for most Poul-Hennings peers. "I have only discussed it with
Jordan [J. K. Hubbard, the FreeBSD's resident humourist], and we agreed that
we needed to do it, so ... I did it!". After a breath he added with a grin:
"My email will probably get an all time 'disk-full' now!".
This will bring quite a flag-day to the FreeBSD developers, the patch-file
is almost 1.4 Megabyte, and they will have to run "make world" to get
entirely -current again. "Too bad, but we just had to do this." Was
the only comment from Poul-Henning to these problems.
When asked how this move would impact the 2.0 release-date, Poul-Hennings
face grew dark, he mumbled some very Danish words while he moved his fingers
in strange geometrical patterns. Immediately something ecclipsed the Sun, a
minor tremor shook the buildings, and the temperature fell significantly.
We decided not to pursure the question.

Are you a dedicated GCC-hacker ?
We BADLY need somebody to look at the 'freebsd' OS in gcc, sanitize it and
carry the patches back to the GNU people. In particular, we need to get
out of the "i386-only" spot we are in now. I have the stuff to take a
gnu-dist into bmake-form, and will do that part.

directories already present in /usr/share, like /usr/share/groff_font and
(particularly) /usr/share/mk.
no longer link against the whole library, since they don't require much
from it, but just compile the few small modules they actually need static.
This should save a measurable amount of space; compare:
-r-xr-xr-x 1 bin bin 155648 Sep 18 18:00 cc1*
-r-xr-xr-x 1 root bin 1048576 Sep 18 17:33 cc1.noshae*
Of course, the library takes up a bit of space, but when you add in the
savings from the C++ compiler, you more than make up the difference:
-r--r--r-- 1 bin bin 1157344 Sep 18 18:27 /usr/lib/libcc_int.so.26.0
-r-xr-xr-x 1 bin bin 491520 Sep 18 18:27 /usr/libexec/cc1plus*

referenced unlinked copy of the hints file created by running
ldconfig in /etc/rc caused the file system to be unclean after
every reboot.

target was not created either so "make depend" always found work to do.
Subject: man returns 1
In 1.1.5.1, man returns a status of 1 if the lookup succeeds and 0 if
it fails. Here is a patch for what I believe is a simple oversight:

FreeBSD system sources installs itself as the standard cc and c++. I've
fixed c++ to call cc instead of gcc and removed all the symlinks
that get created to g** version of the binaries. This means that
you can install a second version of gcc that does use the g prefix
alongside the "system" version of gcc. The only conflict is libgcc
but since we install it as libcc.so.26 and nothing else is likely
to that should be ok.

This is a greatly pared down version of the full gdb-4.12, all the
config stuff has been removed and the supporting libraries have
been stripped to a minimum. This is a 1.1.5 only port, I'll do a
more complete port for 2.0 which will have all the config stuff
and will install the gnu support libraries as system libraries like
we do for readline.
There wasn't much point for 1.1.5 since only gdb would use them so I
went for saving space instead. For 2.0 I'll config all the
other gnu tools to use them as well.
The following two patches should allow the documented "-I !" option to
skip the ignore lists and import/update all files in the directory.

now, DO_COMPRESS. This controls whether or not catpages are compressed or
not (on by default, since little else uses the catpages and those few things
that do can always configure in a `zmore' in place of more or something, and
saving space is more important, IMHO).
Uncompression support is now on by default since that's the only way to support
mixed-mode environments. If you don't like it, just don't compress your man
pages and it won't be used! :-). Supports gzip. You can also compress
the man pages themselves (or gzip them) now and it will work.
late stage due to the fact that link.h was copyright Sun Microsystems.
This version of ld sync's us up with NetBSD's ld and supports compatablily
with NetBSD's -[zZ] flags (which we had reversed). Compiling with this
new ld will give you RRS warnings for libraries which do not contain .type
infomation - these wsarnings are harmless and will go away as soon as you
recompile your libraries (cd /usr/src; make libraries).

These files aren't really necessary to us, but should be kept in sync anyway.

You write that
LDFLAGS+= -Xlinker -Bstatic
no more needed, but you have
CFLAGS += -static -I$(.CURDIR) -I$(.CURDIR)/$(MACHINE)
This -static doesn't make any sense in your version,
because it not passed to linker's state (LDFLAGS),
so we have SHARED /usr/bin/ld in this case.
(Older Makefile produce non-shared ld).
I suppose, that -static in CFLAGS was introduced to
make non-shared ld, so I restore previous LDFLAGS
to have non-shared ld. If we want to have shared ld
we need to remove -static from CFLAGS too, not only LDFLAGS,
but this need special issue and corresponding
commit log. Your current version hang into intermediate
state (beetween two sides), so I move it to one side.
Second, I restore NOPIC dependance again from older Makefile:
.if !defined(NOPIC)
SUBDIR+= rtld
.endif
We don't need ld.so, if NOPIC
P.S. I don't see any purpose to commit new makefile, old version
is better.

As Paul told me, it is only informational, nothing more.
I don't want several screens of this information

On any other system -z means "standard" ZMAGIC format and is the
default. Therefore I've made -z be standard ZMAGIC and -Z be ZMAGIC
stored in the new a_midmag format.
The "standard" ZMAGIC format is now the default as well.

to output the same QMAGIC format as BSDI does. This is triggered by
a new '-q' flag ('-Xlinker -q' in gcc). The default can be changed from
ZMAGIC to QMAGIC by defining DEFAULT_MAGIC=QMAGIC when building ld.

Fixed bug that was reported (with patch) on gnu.utils.bug.
Immediate operands of the pushw instruction were being output as 32
bits, rather than the 16 bits they were supposed to be.
ld won't generate output if there are two .o files with the same
name. It thinks they are multiply defined external references. This
patch explictly allows multiple /file names/ with the same value.
This can happen if you do a two stage link or if you link in file
names that are identical to files in libc.
Otherwise ld.c exits with a status=1 and non error message. Rich

things easier when it comes time to update to a newer version of
