            Bug ID: 214902
           Summary: head -r309179 buildworld on powerpc64 via clang 3.9.0:
                    llvm::sys::CompareAndSwap and llvm::sys::MemoryFence
                    undefined so build stops
           Product: Base System
           Version: CURRENT
          Hardware: powerpc
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: markmi at dsl-only.net

[The powerpc64 self-hosted buildworld failure is for undefined
references to llvm::sys::CompareAndSwap and
llvm::sys::MemoryFence. See later below.]


I cross built TARGET_ARCH=powerpc64 head -r309179 via . . .
(has workaround matching -r309201 and my PowerMac G5 booting hack)

buildworld via clang 3.9.0 and it using powerpc64-binutils
buildkernel via powerpc-xtoolchain-gcc (and so powerpc64-binutils)

and installed and booted the combination:

# clang --version

3.9.0)

I then attempted a self-hosted buildworld but it failed with:
