Diagnostic message "function was not vectorized: unsupported loop structure" is RETIRED.
NOTE: The diagnostic message "function was not vectorized: unsupported loop structure” 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 loops failed to fulfill the requirements of countability, single entry and exit, etc. Latest officially supported versions of the compiler as mentioned earlier, should not emit this diagnostic due to several enhancements in the compiler.
