Add compiler support for the ARM EABI.

ARM EABI support is disabled by default and can be enabled by setting
WITH_ARM_EABI when building, however only the kernel-toolchain target will
work with this flag until the rest of the support is added.

Add src.conf option WITH_SHARED_TOOLCHAIN to enable building the
toolchain binaries as dynamically linked. Option is disabled by
default.

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.

NOSHARED -> NO_SHARED

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).

Update bmake bits to build GCC 3.3.1-prerelease.

Gperf is usable again.

Don't depend on gperf.

Restore some of the implementation from the Bmake gcc 2.95 bits.
In the end, I can do things more like the previous Bmake bits than was
apparent in the middle of the gcc31 WIP.

I was finally able to repeat the -j breakage on one of my machines. Fix it.
I borrowed some ideas from Ruslan, and made the style match cc_tools/Makefile

Tidy up the cleanfiles.

Bmake bits for Gcc 3.1.

Change YACCing.

Submited by: ru

Fine! I cannot freaking take the bikeshed any more.
These binaries will be static, peroid.

Set NOSHARED conditionally.

Clean up the YACCing. I don't know why we cannot leave the .y's as .y's.
So lets see if doing so causes anyone trouble.
Also use make(1)'s assistance in using the right file. It knows the
dependency, so lets just ask it.

Drop the use of Bison for Byacc now that we don't need to depend on the
--broken-undeftoken-init Bison 1.25 bug.

Minor cosmetic changes in an attempt to improve consistancy.

$Id$ -> $FreeBSD$

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 Bison with "--broken-undeftoken-init".

Only use Bison to generate cc1plus's parse code.

Use Yacc rather than Bison.

The Unix way is arguments come before an input file name, not after.

NOSHARED takes a yes/YES no/NO value, not "true, false, hey mon!".
NOPIC is used to not generate a shared library, not NOSHARED.
Make NOSHARED advisory where appropriate.
Remove bogus NOSHARED (kbdio).

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.

Remove the partial support for a shared -lcc_int, since it's been unusable
for a fair while. cc1, cc1plus etc have been linked static for some time.

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.

Make cc1plus smaller and faster as was done for cc1 by linking static.

Stop using gnumalloc.

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.

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*

Use gnumalloc to help reduce memory consumption.

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,

Here comes the right import of gcc-2.6.0.
