This might be useful for debugging applications that use a special LDT.
However, printing of all segment registers is currently broken.
Don't print "last exception: " before the FPU opcode and pc, etc. The
opcode and pc, etc., are for the last FPU _instruction_.
Pass the saved exception status word to print_387_status() so that the
exception(s) that caused or will cause a trap can be seen. The kernel
has supported this since 1.1 or before. The kernel still clobbers the
tag word if a trap occurs.
Remove unused null function clear_regs().
cvs is not being used effectively for gdb. Our old changes get clobbered
and our new changes are mixed with "vendor" changes in the same updates
so they will be difficult to untangle for the next release of gdb. 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..

This fixes the problem with parse errors in header files when compiling C++
files.
Recompiling libg++ also solves the undefined synbols problem.
Notice that the libgcc DOESN'T change number, because there are no
changes.
Also now the gnu2bmake stuff is synchronized again.
I commit this so that others can test too.
You might want to postpone any "make worlds" until tomorrow, to
avoid any problems I didn't see in the first pass.
Thanks to Bruce for rounding up our changes to gcc.

When we get an EN8 response while we're already sending the file using
the i protocol, this can happen:
In send.c, flocal_send_await_reply() is called. This function calls
flocal_send_fail() to process the aborted transfer. After this, we run
into the branch that calls ffileseekend() to force the end of the
actual transfer.
Now flocal_send_fail() frees qtrans, but qtrans is still used later!
I propose to fix this by moving the usfree_send(qtrans) out of
flocal_send_fail(), as in the patch I append to this mail.
...
I have found a race condition in the uucp 1.05 code. The typical result
is that the connections mysteriously fails with "conversation failed",
even while all files were transmitted. This is the problem:
At least for the i protocol, the code to send a packet can receive and
process packets after sending.
In several places in the code, we send a command and then prepare to
receive an answer.
Now the answer might already arrive during the call that sends the
command while we aren't ready to process it.
The general solution is IMHO first to do all preparations and only as a
last step to send out the command.

I know that many of these entries are bogus and need to be revisited,
but let's get the tree working again for now and then do a pass through
looking at all the __FreeBSD__ entries, shall we?
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.
Please apply to phk@freebsd.org

Perl's scripts are still trying to execute perl out of /usr/gnu/bin/perl.
The hack Larry was using for h2ph.1 doesn't work with the new macros, so
make it a real man page.
Also, we weren't building the .ph files, add them as an afterinstall rule

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*
completely when ldconfig unlinks it. If init is shared, then the
referenced unlinked copy of the hints file created by running
ldconfig in /etc/rc caused the file system to be unclean after
every reboot.
You need to fix the libio/_G_config.h file around lines 42-44. After
that everything should be OK. You should have seen many warning error
messages about this file. There are missing "short" "char" keywords
the file.

to be recompiled. I suspect that the dependencies aren't complete
enough to do this automatically.
automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
Several files in uucp/libunix included <sys/dir.h> and defined dirent
as direct, but <sys/dir.h> defines direct as dirent. This macro
recursion is not allowed by cpp in traditional mode. The 2.0 mkdep
uses cpp in traditional mode (another bug) so cpp prints a error
message and exits with a nonzero status. The error status leaks out
of the pipe (another bug) so mkdep "succeeds". It may even succeed.
