Hi all, I'm trying to implement llvm.memory.barrier on PowerPC. I've modelled my patch (attached) on the implementation in X86, but when I try and compile my test file (also attached) with llc I get the error "Cannot yet select: 0x10fa4ad0: ch = MemBarrier 0x10fa4828, 0x10fa4c68, 0x10fa4be0, 0x10fa4be0, 0x10fa4be0, 0x10fa4be0". This presumably means my "membarrier"
