      Description

      MCS now supports SSE4.2/NEON to vectorize execution. This project will look into function multiversioning feature of gcc and clang compilers. The feature description is available [herehttps://gcc.gnu.org/wiki/FunctionMultiVersioning].
      The goal is to asses how MCS runtime can leverage this feature to pick/use the best SIMD instruction set available for the platform.
