Diagnostic message"function was not vectorized: operator unsuited for vectorization”is RETIRED.
NOTE: The diagnostic message "function was not vectorized: operator unsuited for vectorization” is retired in the officially supported versions of the Intel(R) C++ Compiler 15.X and the current 16.X respectively. Previously, older versions of the compiler emitted the diagnostic when certain operators, such as the "%" (modulus) operator, can't be vectorized.
