Actually, I found a case where the zig compiler does optimize more in ReleaseFast mode than ReleaseSmall mode: if you do operations on a vector's elements one by one, ReleaseFast will use SIMD instructions, but ReleaseSmall will not. Of course, if you just use a vector operation, even ReleaseSmall will use SIMD instructions. https://godbolt.org/z/jrWTbqEGG
