General Information

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:

arch 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
