You compiled with auto-vectorization enabled; however, the compiler did not vectorize the code. Explore vectorization opportunities:
- Run a Dependencies analysis to identify real data dependencies that could make forced vectorization unsafe.
- Microsoft Visual C++* compiler: Use the Qvec-report compiler option (i.e. /Qvec-report:2) to set the
- Auto-Vectorizer Reporting Level to output missed optimization opportunities.
- GNU* gcc compiler, do one of the following:
- Use the fopt-info-vec-missed compiler option to output missed optimization opportunities.
- Use the OpenMP* omp simd directive to tell the compiler it is safe to vectorize.
- Use additional auto-vectorization directives.
