MFC r245882,245898

Reorder so that NO_MAN is declared before bsd.own.mk is included and thus
has an effect (not installed a g++.1 manpage over the g++.1(.gz) link
created in ../cc).

bsd.own.mk needs to be included before Makefil.inc so MK_ARM_EABI is defined

MFC 232322:
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 232323:
Regenerate src.conf(5) after r232322.

MFC 232477:
In r232322, I forgot one case where a check for MK_CLANG_IS_CC was
needed, in sys/conf/kern.pre.mk. Add it now.

MFC 232522:
Fix a thinko in r232322, where gcc (and its tools) are not built during
the cross-tools stage, if CC=clang and WITH_CLANG_IS_CC is not set.

This causes no 'cc' to be installed in the temporary cross-tools tree,
making lint fall over later in the build, because it ignores ${CC} and
attempts to run 'cc' anyway.

To fix this, only skip building gcc during cross-tools, if WITHOUT_GCC
is set, or if WITH_CLANG_IS_CC is set.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

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.

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Bmake glue for GCC 3.4.2-prerelease.

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

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.

Add libcc_fbsd.a that contains libc and libiberty routines needed in
bootstraping on FreeBSD specifically.

3.2 upgrade path tested by: marcel

Cut over the system compiler from from EGCS 1.1.2 to GCC 2.95.2.

$Id$ -> $FreeBSD$

Purely cosmetic cleanups.
- Id tag layout wrong.
- "FOO =" -> "FOO=".
- 4 space indention on continuation lines rather than a <tab>

Basic idea checked by: bde

Use inherited BINDIR defintion.

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

I goofed on the `LINKS' syntax.
Submitted by: Dmitrij Tejblum <dima@tejblum.dnttm.rssi.ru>

add `CC' as a link to `c++' for compatablity with SGI.

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.

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.

Link g++ -> c++, like I did with gcc -> cc. This is evil, but it's
now at least orthogonal evil.

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.

This commit was generated by cvs2svn to compensate for changes in r1823,
which included commits to RCS files with non-trunk default branches.

Here comes the right import of gcc-2.6.0.
