What advantages over OpenMP does Agner Fog's VCL have?
Agner Fog has this [C++ Vector Class Library](https://www.agner.org/optimize/vcl_manual.pdf), which is > ... useful for improving code performance where speed is critical and where the compiler is unable to vectorize the code automatically in an optimal way. However, it looks like OpenMP `simd` construct offers exactly this, and much more. OpenMP has it since version 4.0 (2013), i.e. for a long time. Does the VCL have any advantages when used with a compiler which supports OpenMP 4.0?
