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.

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.

NOSHARED -> NO_SHARED

Bmake glue for GCC 3.4.2-prerelease.

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

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.

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)

First round of changes to support generation of assembler for the old
a.out gas and the binutils gas (elf or a.out) with a single compiler.

This uses other infrastructure not yet committed, in order to support
both a.out and elf it needs to be able to get to both a.out and elf
gas, ld, libs, crt* etc. So for now, the support is pretty much dormant.

The new freebsd.h file is based on the old freebsd-elf.h file (which has a
long lineage, right back through linux and svr4 files). The change is
pretty dramatic from a gcc internals standpoint as it overrides a lot of
definitions in order to generate different output based on target mode.
There is potential for screw-ups, so please be on the lookout - gcc's
configuration mechanism wasn't really meant for this kind of thing.
It's believed to compile world etc just fine under both a.out and elf, can
handle global constructors and destructors, handles the differences in
a.out and elf stabs, and what sections things like exceptions go in.

The initial idea came from i386/osfrose.h which is a dual rose/elf format
target. These two are not as diverse as a.out and elf it would seem.

The cc front-end uses external configuration to determine default object
format (still being thrashed out, so read the source if you want to see
it so far), and has a '-aout' and '-elf' override command line switch.
There are some other internal switches that can be accessed, namely -maout,
-mno-aout, -munderscores and -mnounderscores. The underscore and local
symbol prefixing rules are controllable seperately to the output format.
(ie: it's possible to generate a.out without the _ prefixes on symbols and
also to generate elf with the _ prefixes. This isn't quite optimal, but
does seem to work pretty well, except the linkers don't always recognise
the local symbols without their normal names)

The default format is a.out (still), nobody should see any major changes.

With both elf and a.out tools and libraries installed:

[1:26pm]/tmp-223> cc -elf -o hello hello.c
peter@beast[1:27pm]/tmp-224> file hello
hello: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD), dynamically linked, not stripped
[1:27pm]/tmp-225> ./hello
hello world!

[1:27pm]/tmp-226> cc -aout -o hello hello.c
[1:27pm]/tmp-227> file hello
hello: FreeBSD/i386 compact demand paged dynamically linked executable not stripped
1:27pm]/tmp-228> ./hello
hello world!

Since my co-conspirators put a lot of effort into this too, I'll add them
so they can share the blame^H^H^H^H^Hglory. :-)

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.

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.

Add some missing MLINKS, correct some cross references, correct some
file locations and some minor formatting/style problems.

Install also a gcc.1 manual page as a link from cc.1, as long as
we have the link cc to gcc.

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.

Add LINKS to get gcc back.

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.

Fixed up everything so that the version of gcc that we install from the
FreeBSD system sources installs itself as the standard cc and c++. I've
fixed c++ to call cc instead of gcc and removed all the symlinks
that get created to g** version of the binaries. This means that
you can install a second version of gcc that does use the g prefix
alongside the "system" version of gcc. The only conflict is libgcc
but since we install it as libcc.so.26 and nothing else is likely
to that should be ok.
