Are the following TARGET_ARCH=powerpc and TARGET_ARCH=powerpc64
items from llvm going to be taken care of before the merge of
clang 3.9.0 into head? If not, is there a plan to sometime after
the merge?

            Bug ID: 214433
           Summary: projects/clang390-import: powerpc and powerpc64
                    support needs to pick up two fixes from llvm (ABI fix
                    for ppc; softfloat enabled for ppc64)
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

There is a powerpc llvm tack-handling ABI violation bugfix and a powerpc64
softfloat support addition (needed for libstand) that have yet to be merged
into projects/clang390-import (if they reasonably fit).

Both of these fixes are ones required for FreeBSD to support using clang for
powerpc and powerpc64 targets. (llvm's bugzilla still has some of the C++
exception handling defects waiting for fixes. But the two fixes below should
allow more testing and possibly finding of additional things that need to be
worked on for FreeBSD to use clang for powerpc and/or powerpc64.)

The llvm reports of fixes are:
