It should, but I've heard a pretty convincing argument that
wherever you could use register (i.e., local scalars), a modern
compiler can figure out that it isn't aliased all by itself, so
it doesn't gain you anything.
However, you _can_ tell the compiler to operate as though some
aliasing wasn't present by explicitly using local temporaries,
rather than operating on array elements.
