Like I asked before -- should we run this emulation on 32-bit machines at all? The instruction only exists in the 64-bit architecture after all.
It could be argued either way, but on the whole I would prefer to minimize the number of things which could cause a 32-bit program that runs quite happily on a 64-bit CPU to fail on a 32-bit CPU... Paul.
