Following on from the recent announcement of the new IBM z13, HLASM has been updated to support the new instructions. HLASM APAR PM79901 introduces over 660 new mnemonics and extended mnemonics to support the new instructions. The new instructions are available in both the new ZS7 OPTABLE as well as the UNI OPTABLE. Full details on how to code the new instructions will be available in the zArchitecture Principles Of Operation guide.
There are however a number of new zArchitecture vector instructions using the same mnemonics as old ESA/390 vector instruction mnemonics. These old ESA/390 vector instruction mnemonics have therefore been removed from the UNI OPTABLE, but are still available in the ESA OPTABLE. It is important that if you have ESA/390 vector instruction mnemonics in your code that after applying APAR PM79901 you use the ESA OPTABLE when assembling code containing the ESA/390 vector instruction mnemonics. Whenever new instructions become available in hardware and extra mnemonics and extended mnemonics are added to HLASM, there is always a potential for a clash between the new mnemonics / extended mnemonics and existing user macros with the same name. To assist in identifying any such macros, we have released a technote which details how SuperC (ISRSUPC) can be used to assist in finding such clashes in your source and macro libraries. The technote also gives guidance on how such clashes may be resolved.
