[vector] Internal representation byte[] reorder doesn't support SVE

    Details

    • Subcomponent:
    • CPU:
      aarch64
    • OS:
      generic

      Description

      In class AbstractShuffle, reorder is defined as follows:
        // Internal representation allows for a maximum index of 256
          // Values are clipped to [-VLENGTH..VLENGTH-1].
          final byte[] reorder;

      But for AArch64 SVE, maximum length is 256(2048/8 bytes). So that byte data type is not enough for SVE. We should consider expanding byte to another data type, such as short.
