      1 IBM Z mainframes starting from version z13 provide vector instructions, which 
      2 allows vectorization of crc32. This extension is build by default when targeting
      3 ibm s390x. However this extension can disabled if desired:
      4 
      5     # for configure build
      6     $ ./configure --disable-crcvx
      7 
      8     # for cmake build
      9     $ cmake .. -DZLIB_CRC32VX=off
