DIRDEPS_BUILD: Update GCC dependencies.

Sponsored by: EMC / Isilon Storage Division

META_MODE: Remove DEP_RELDIR from Makefile.depend files.

This has not been needed since r284171 in projects/bmake.

Sponsored by: EMC / Isilon Storage Division

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Differential Revision: D2796

Use src.opts.mk in preference to bsd.own.mk except where we need stuff
from the latter.

Add a WITH_CLANG_IS_CC option for src.conf(5), disabled by default, that
installs clang as /usr/bin/cc, /usr/bin/c++ and /usr/bin/cpp.

Note this does *not* disable building and installing gcc, which will
still be available as /usr/bin/gcc, /usr/bin/g++ and /usr/bin/gcpp. If
you want to disable gcc completely, you must use WITHOUT_GCC.

MFC after: 2 weeks

Update bmake glue to build GCC 4.2.

Also:
Switch FreeBSD to use libgcc_s.so.1.

Use dl_iterate_phdr to locate shared objects' exception frame
info instead of depending on older register_frame_info machinery.
This allows us to avoid depending on libgcc_s.so.1 in binaries
that do not use exception handling directly. As an additional
benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

Build newly added libgomp.so.1 library, the runtime support
bits for OpenMP.

Build LGPLed libssp library. Our libc provides our own
BSD-licensed SSP callbacks implementation, so this library
is only built to benefit applications that have hadcoded
knowledge of libssp.so and libssp_nonshared.a. When linked
in from command line, these libraries override libc
implementation.

Prepare to pick up manpages from their new location.

Remove redundant defines alerady set by Makefile.fe

Fixed style of DPADD and LDADD assignments as per style.Makefile(5).

Use
cat ${.ALLSRC} > ${.TARGET}
rather than
ln -sf ${.ALLSRC} ${.TARGET}
not to depends on absolute-path of symbolic links.

The best we can do about man pages for the moment.

We don't need this library any more.

Bmake bits for Gcc 3.1.

Partially made possible by: Wilko.Bulte@compaq.com

Move some cflag contents down to where they are acutally used.

Merge cc_drv into cc_int. Merge more shared files into cc_int.

Turn on a new /usr/bin/cpp that is a true binary rather than a shell script
wrapper. /usr/bin/cpp knows about all the GCC predefined symbols and has
the functionality of the previous EGCS 1.1.2 /usr/libexec/cpp.

Didn't get these PREFIX specifiers removed with Makefile.inc rev 1.48.

Minor cosmetic changes in an attempt to improve consistancy.

$Id$ -> $FreeBSD$

Use Yacc rather than Bison.

Minimum set of changes to switch from Gcc 2.7.2 (in contrib/gcc) to Egcs 1.1.2
(in contrib/egcs)

Simplified using new yacc rules. This is cosmetic - the old rules worked
with `make -jN' because they did the right things to generate cexp.h
without clobbering cexp.c, and there were no missing dependencies on
cexp.h because cexp.h isn't actually used.

Fixed style bugs.

Changes to support full make parallelism (-j<n>) in the world

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

cpp was named ccp.

Crude hack to work around cpp.1 doing a .so man1/cccp.1

Man the lifeboats! Tie down the hatches! Red alert! Activate gcc-2.7.2.1!

(the old cc has been tagged with "gcc_2_6_3_final" so we have a reference
point in case of unforseen disasters...)

This has the objc backend active, and I think I've managed to get the
f77 f2c support through in one piece, but I don't know fortran to test it.

A 'make world' change and libobjc commit will follow.

If you normally do 'make -DNOCLEAN world', do not do so this time, I know
it can fail with groff.

This version of gcc makes a **LOT** more warnings on our kernel.

Remove trailing whitespace.

Updated the sources to gcc 2.6.3 with FreeBSD changes already applied.
Note: This isn't the most correct way, but it works and it's fast.

"Various very violent dissections
disables dysfunctional disinformed namei's,
needlessly negating namei cache."

These hacks cuts the number futile attempts made by cc and ccp to find
cross-compilers and other weird stuff. A make of the BOOTFLP kernel
has 20% less namei calls now, that is from 30647 down to 24563 calls.

Integrated GCC-2.6.1 -> GCC-2.6.2 changes.

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.

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.

JOB-SECTION
-----------
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

No Novice Need Apply.

Put a real man page in for cpp(1)... it needs to be converted to the mandoc
macros, but it's good enough for now.
Obtained from: gcc 2.6.0 gnu distribution

Make GCC's back end be shared among all languages. cc, c++, and cpp now
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*

Add dependencies on libraries to DPADD. Someday this should be done
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.
