ut_fold_ull() is a waste on 64-bit systems

    XMLWordPrintable

Details

    Description

      On 64-bit CPU architectures, the default InnoDB data type ulint, which is an alias of size_t is 64 bits wide.

      The function ut_fold_ull() is converting a 64-bit integer to ulint. This may make sense on 32-bit systems, but we could avoid the extra instructions on 64-bit systems and just use the 64-bit index or table identifiers as is.
