Found this while trying to build llvm-gcc for arm to work on another bug :-(

$ llc test.ll  -march=arm
LLVM ERROR: Cannot yet select: 0x1eeb170: ch = ARMISD::MEMBARRIER 0x1eeacf0,
0x1eeb458
$ cat test.ll
define arm_aapcscc void @f() {
entry:
  tail call void @llvm.memory.barrier(i1 true, i1 true, i1 true, i1 true, i1
false)
  unreachable
}

declare void @llvm.memory.barrier(i1, i1, i1, i1, i1) nounwind
