Hi, Everybody, Various people disagree about whether I should multiply by a reciprocal when I could do a floating point division instead. Others tell me that it's best to let the compiler replace integer division by a power of two with a right shift. If I do either optimization by hand, will that prevent the compiler from noticing other optimizations it could do? I've read somewhere that I should let C compilers do the optimizations I've described. Is that true about gcc's C compiler? Is it bet for me to trust it to do optimizations I could do? Thanks.
