HLASM APAR PH39324 mentions new op-codes ...
The following mnemonics are new extended mnemonics for existing
instructions and are listed in the new very helpful Appendix J
of z/Architecture Principles of Operation.
1. Alternative mnemonics for existing instructions which fit
into more than one naming pattern:
LFI for IILF, LLGFI for LLILF
2. Shifts involving high word, mapped to RISBHGZ and RISBLGZ:
SLLHH, SLLHL, SLLLH, SRLHH, SRLHL, SRLLH
As they are all extended mnemonics, they are not normally used
by debugging tools. They are not used by the HLASM disassembler.
