Bug Description
SRU Justification:
==================
[Impact]
* As of today the architectural (level) name 'arch14' is used
as CPU name for the new IBM z16 system.
* The real name 'z16' couldn't be used until officially announced.
* That happened meanwhile, hence we can now add and use the real name.
[Test Plan]
* Check if the same (proper) opcodes are detected on an IBM z16
system with and without the patch.
Since only the identification and name of a z16 system was modified.
* Or the simplest test is probably to check
(after having 'binutils' installed on an Ubuntu 22.04 s390x system)
if not only:
'as -m64 -march=arch14 --target-help'
but also:
'as -m64 -march=z16 --target-help'
succeeds and leads to the same output.
(As it does for '-march=arch13' and '-march=arch15'.)
[Where problems could occur]
* Issues could happen if the conditional statement that look
for architectural / CPU name are paired wrongly, since:
* 'z16' belongs to 'arch14', 'z15' to 'arch13', etc.
* If these pairs are not handled correctly,
or the identification is erroneous
a wrong system might be identified and wrong instructions used etc.
[Other]
* This is a hardware enablement SRU to enhance the IBM z16 support.
__________
After the announcement support for the official machine name z16 has been added to binutils. Please consider picking up the following patch from 2.37 branch:
commit e24d2a2d11008aa
IBM zSystems: Add support for z16 as CPU name.
So far z16 was identified as arch14. After the machine has been
announced we can now add the real name.
