z17 Mainframe Support Added to Z/XDC

I have added disassembly support for all new opcodes and extended mnemonics as documented in the recently published -14 edition of z/Architecture Principles of Operation.

The added instructions are new with IBM's z17 Mainframe.

Z/XDC's FORMAT command (and friends) use disassembly to display machine code when:

  • An ADATA map is unavailable for formatting the storage being displayed,
  • Or SET FORMAT OBJECT is in effect.
