Support added for the new Z16 Machine Instructions

IBM's new Z16 machine brings with it 22 new machine instructions as well as 16 new extended mnemonics. We have just published DBC-2206D to add support into z/XDC for formatting and displaying these new instructions.

The new instructions include:

  • NNPA for accessing the AI coprocessor,
  • LBEAR, STBEAR and LPSWEY for managing the Breaking Event Register,
  • SORTL for directing complex sorts,
  • as well as several vector related instructions.

In addition, a few formatting errors for existing instructions were discovered and fixed as a part of this update. In particular, I would like to thank Eric Johnson of Broadcom for bringing one of those errors (CGDR) to our attention.
