Where is the fast inverse square root function in Rust ?
http://en.wikipedia.org/wiki/Fast_inverse_square_root

Anyone know if this semi-accurate function is at a hardware level and built
in to Intel chipsets since MMX ?

How does this affect LLVM and Rust compilation on 64 bit ?

Thanks in advance,
