Thus we'd need an Extended emulator for platforms that don't have a 80-bit float type. The calculations might be done using SSE2 instruction set on x86_64 cpus

SSE2 does not support more than 64 bit precision for floating point.

We do need an 80 bit floating point emulator: http://bugs.freepascal.org/view.php?id=9262
