For final output files create them with mode 0664 to match other
compilers and expected defaults.
This should fix clang creating files with mode 0600.

Revert r115805. An array type is required to have a range type,
however, the range can be unknown for the upper bound.
Testcase to follow.

This should fix ctfconvert producing error messages during kernel
builds, similar to:
ERROR: scsi_all.c: die 24561: failed to retrieve array bounds
These were caused by incorrect debug information for flexible array
members of structs.

Make our handling of MMX x SSE closer to what gcc does:
* Enabling sse enables mmx.
* Disabling (-mno-mmx) mmx, doesn't disable sse (we got this right already).
* The order in not important. -msse -mno-mmx is the same as -mno-mmx -msse.
Some configure scripts depend on this.

Make sure the non-SSE lowering for fences correctly clobbers EFLAGS.

In particular, this fixes segfaults during the build of devel/icu on
i386. The __sync_synchronize() builtin used for implementing icu's

Fix the signature of the getcontext builtin, eliminating incorrect

This also adds a -W(no-)builtin-requires-header option, which can be

Mark the overloaded atomic builtins as having custom type checking,
which they do. This avoids all of the default argument promotions that
we (1) don't want, and (2) undo during that custom type checking, and
makes sure that we don't run into trouble during template
instantiation. Fixes llvm/clang PR11320.

LLVM_HOSTTRIPLE that is defined during the cross-tools stage.
Using clang, you can now build amd64 world and kernel on i386, and vice
versa. Other arches still need work.
There are several bugfixes in this update, but the most important one is
to ensure __start_ and __stop_ symbols for linker sets and kernel module
metadata are always emitted in object files:
http://llvm.org/bugs/show_bug.cgi?id=9292
Before this fix, if you compiled kernel modules with clang, they would
not be properly processed by kldxref, and if they had any dependencies,
the kernel would fail to load those. Another problem occurred when
attempting to mount a tmpfs filesystem, which would result in 'operation
not supported by device'.
arguments passed to ld, when linking. This was to appease configure
scripts in several ports, that grep for such a -L option in "${CC} -v"
output, to determine the startup objects passed to ld. Note ld itself
does not need to be told about /usr/lib, since it has this path builtin
anyway.
However, if clang is built as a bootstrap tool during buildworld, it
should not use *anything* outside ${WORLDTMP} to include or link with.
The upstream fix to add -L/usr/lib breaks this assumption, and can thus
cause libraries from /usr/lib to be linked in during buildworld.
This can result in buildworld dying during linking of zinject, where it
picks up the wrong copy of libzpool.so, eventually leading to:
/usr/obj/usr/src/tmp/lib/libthr.so.3: undefined reference to `_rtld_get_stack_prot'
Fix this issue by not adding any hardcoded paths, but by looping through
the run-time library path list, which is already correctly set for the
bootstrap phase.

make it like xArg because they are different ('x' doesn't accept sign,

This fixes some warnings when building DDB with clang.

Make "clang -print-multi-os-directory" return "." on amd64, matching

This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
has been renamed to /usr/include/clang/2.8.

I've looked at other places in the source tree where CLANG_VENDOR is
used and I suspect it might not be safe to use newlines here.
CLANG_VENDOR should just be defined to "FreeBSD ", just like the latest
Clang preview in OS X uses "Apple ". Properly use SVN_REVISION to define
it to the imported revision of Clang. I do want to have a date in there,
so slightly modify the code to support CLANG_VENDOR_SUFFIX.
Even though Roman removed these directories in his working copy, they
