There is lots of room in the E3xx range close to CGH and/or LGH.
E310 to E312 and/or E337 thru E33D
We will see next month.

I've been converting some code to use full 64-bit registers lately, and
was greatly surprised that there appears to be no AGH (Add Halfword (to
64-bit register)). There's LGH, and even CGH, as well as AGHI (much
less
XI** are more important in my opinion.

Well, that's disappointing. I always thought the system architects were
damn close to being infallible and omnipotent :-).
Steve, all
It does look like AGH is missing. If not using register is more important
than being RENT, here is test macro program which uses MVC and AGHI:
* TEST AGH MACRO WHICH AVOIDS USING EXTRA REGISTER
* BUT IS NOT RENT
* DON HIGGINS 06/24/13

MVC
I'll put in my comment. I don't think that the current z architects are
driven by how will assembler programmers use the architecture any more.
Neither are they theoretical computer architects who are wedded to an
orthogonal instruction set. To me, many of the new instruction have been
introduced

With a suitable work area, a RENT version could be designed.

Thanks. But that makes them even more expensive to implement. Which could
be a further reason as to why they weren't.
