Number Mode

LuaJIT already has a dual-number mode (mixed integer/double), which predominantly uses integer computations. On ARM you get soft-float support, too.

Here are the supported configurations:

     |  number modes |   FPU    |      ABI      |
-----+---------------+----------+---------------+
x86  | single|(dual) | x87|SSE2 |    hardfp     |
x64  | single|(dual) |   SSE2   |    hardfp     |
ARM  |      dual     | soft|VFP | softfp|hardfp |
PPC  |  dual|single  | FPU-dbl  |    hardfp     |
e500 |     single    |   SPE    |    softfp     |
MIPS |     single    | FPU-dbl  |    hardfp     |
