Unaligned access on aligned pointer?

Question

I have this function code:

bool interpolate(const Mat &im, float ofsx, float ofsy, float a11, float a12, float a21, float a22, Mat &res)
{         
   bo         


        

Answer 1

The compiler sees out++. It can't stay aligned.

(That is to say, it remains aligned for float* access, but the message refers to SIMD vectorization which requires a stricter alignment)
