Maybe actual implementations are not fast enough as C++ compilers. In any case, if you are doing ray tracing, none C compiler will do as well as a good assembly coder. It is the nature of the problem: only mathmatics, for which the raw CPU is built in the first place, no compiler can be smart enough to realize how to do operations in the faster order (unless you need to do loophole optimization, for which a good loophole optimizer will be the best and the compiler would be useless). -- I use CAPS to emphasize, not to yell.
