MFC r257530

2013-11-04T23:36:49+00:00

Reimplement r257525 such that it work with the historic FreeBSD make
implementation.  This fixes the toolchain and kernel-toolchain targets
when building from older FreeBSD versions where make is fmake.

Enable the --sysroot=/foo option in ld by always building with a sysroot
defined. When not building as a cross linker, the sysroot is set to "/".

Good bye RCS. You will be missed.

Remove long-unused GNU ar and ranlib

2013-10-01T17:40:56+00:00

The libarchive-based replacements have been used since 2009; the GNU
ones were kept to support source upgrades from FreeBSD 6.

After r255321, clang uses libc++ by default. This leads to a lot of

2013-09-12T21:24:59+00:00

errors when you enable WITH_GNUCXX to build libstdc++, since it will
include C++ headers from the libc++ installation under ${WORLDTMP}, and
those are not compatible with libstdc++ at all.

To fix this, add -stdlib=libstdc++ to CXXFLAGS when building libstdc++
(and its companion libsupc++) with clang.

On platforms where clang is the default compiler, don't build gcc or libstdc++.

2013-09-06T20:08:03+00:00

To enable them, set WITH_GCC and WITH_GNUCXX in src.conf.
Make clang default to using libc++ on FreeBSD 10.
Bumped __FreeBSD_version for the change.

GCC is still enabled on PC98, because the PC98 bootloader requires GCC to build
(or, at least, hard-codes the use of gcc into its build).

Thanks to everyone who helped make the ports tree ready for this (and bapt
for coordinating them all).  Also to imp for reviewing this and working on the
forward-porting of the changes in our gcc so that we're getting to a much
better place with regard to external toolchains.

Sorry to all of the people who helped who I forgot to mention by name.

Remove our hacked GNU patch.

2013-09-03T20:03:10+00:00

The old (2.1) GNU patch has outlived its days.  The major
local changes have been moved into the less restrictedly
licensed patch(1) we adopted in usr.bin/ .

A much newer version of GNU patch is available in the
ports tree (devel/patch).

Disconnect from the build and remove.

add support to gcc for AES and PCLMUL intrinsics... This addes the

2013-09-03T17:33:29+00:00

-maes option, but not the -mpclmul option as I ran out of bits in
the 32 bit flags field...  You can -D__PCLMUL__ to get this, but it
won't be compatible w/ clang and modern gcc...
