Compiler guy here - yes, the optimizer claim is,in fact, just totally wrong. The claim is it can't be constant folded, scheduled, etc because it doesn't turn into simd instructions. At the bottom, as you say, it will turn into code. That code is almost certainly builtins or uses the vector extensions or whatever , not raw asm statements. compilers can and do turn these into ir level simd instructions. |
