[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: > #
