Hi, all:
What version(s) of Hercules-390 support the 390/ESA and newer z/arch. CMPSC opcode (Compression Call)?
(Apparently this was a microcode-assisted implementation of LZ1 on S/390 models, and millicode on z/arch. models)
?
On this page: https://sdl-hercules-390.github.io/html/
?
- I scrolled down to the "Hercules Frequently-Asked Questions" link.
- I selected question 5.01: "What architectural features are implemented?? I see:
?
The following features of ESA/390 have been implemented:
...
Compression
and
?
The following features of z/Architecture have been implemented:
...
CMPSC-Enhancement Facility
...
?
But, further down the page, it says:
The following features of z/Architecture have not yet been implemented:
...
DEFLATE-Conversion Facility
Regarding:
? ? The following features of ESA/390 have been implemented:
and
? ? The following features of z/Architecture have been implemented:
?
Approx. when was each of these features or facilities implemented and in what version/release of Hercules-390.
?
Or, asking another way: can someone tell me where to find such information?
Thanks in advance.
