I have to ask: Why they big concern over a few instructions?
Optimisation of a few is not worth

LOL. If Binyamin's question wasn't worth asking, then IBM would never
have recently introduced the STOC instruction that John McKown so
kindly reminded us about. (Wish we could use instructions like that in
other than our JIT-compiled Java code...)
z/SQL from Rocket Software ships several different run-times all
compiled with different ARCH() options which are loaded at runtime
depending on the hardware. WAS does something similar but it's a manual
selection. That's easy to do if your using a compiler, but a very big
job if you cut your code in assembler.
