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.
