I've ran to some bug in making the integer patch work with 64-bit
integers, as well as 32-bit.
Anyone interested in that work (perhaps someone targetting PS2
platform?) would you please take contact. Would be interesting to get
performance figures on 64-bit optimized (non-FPU) platforms, as well.
In short, the integer patch allows for transparent optimization of
all integer operations, with fallbacks to float/double only when
numbers need them. So, one could i.e. do int64/float or int64/double,
without affecting Lua compatibility in any way (byte codes still
remain float/double only, and this seems to be part of the background
for the bug at hand).
