basic-block profiling:
1. use a .stabs(25) symbol to link all the data structures together with.
The regular method isn't safe for the kernel.
2. add a BB before the prologue and add a BB after the epilogue, this
alows us to find the length of any counted BB. This is a cheap and somewhat
reasonable measure of actual cost.

This is a ported/modified version of the yppush program from the
yps-0.21 package from the NYS project. This program is used to propagate
updated NIS maps from an NIS master to an NIS slave. It's normally invoked
by /var/yp/Makefile.
This version of yppush has been modified in the following ways:
- Cleared up several Linux/BSD incompatibilities, largely involving
header files.
- converted from GDBM to DB with extreme predjudice. (well, not really...)
- removed lots of ugly debugging code that really didn't do anyone any good.
- Fixed a couple of inaccurate/badly formatted error messages.
- Renamed some functions to avoid collisions with certain YP routines
hidden inside libc.
- Small signal handling kludge: Linux has different struct sigaction
that us.
- Incorporated some functions from the yps-0.21 library that yppush was
dependent on.
Like ypxfr, this works, but could use come cleaning up.

only include the highest-numbered shlib anyway, so this is in no way a
limitation of generality.
Caution: after installing the new programs, your /var/run/ld.so.hints

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

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.

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++

Recompiling libg++ also solves the undefined synbols problem.

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.

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

and /usr/share/perl (library). The latter was chosen as analogous to other
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*
