// FIXME: This is a horrible way of checking the output, we need an llvm-mc
// based 'otool'.

// This is a case where llvm-mc computes a better layout than Darwin 'as'. This
// issue is that after the first jmp slides, the .align size must be
// recomputed -- otherwise the second jump will appear to be out-of-range for a
// 1-byte jump.
