John Paul Adrian Glaubitz added the comment: > So IMO it's fine to remove the support. You are not removing "support". You're just disallowing users to use the Python interpreter - which works perfectly fine on all architectures we have in current and previous releases - on Debian. A few pr

Charalampos Stratakis added the comment: And to dig a bit further with a semi-official answer. RHEL4 had standalone support for s390, while since RHEL5+ we've had only multilib support (64 bits kernel and possibility of s390 userspace packages). RHEL7 that is the oldest currently supported R

Charalampos Stratakis added the comment: For RHEL7 which is the older OS that buildbots are still running, only the System Z architecture is supported. From the release notes [0]: Note that Red Hat Enterprise Linux 7 supports IBM zEnterprise 196 hardware or later; IBM System z10 mainframe sy

[issue43179] Remove 32-bit s390 Linux support (s390-linux-gnu triplet)

STINNER Victor added the comment: > s390 is a 31-bit platform, not a 32-bit platform. ARM64 only uses 48 bits for the address, but it uses 64-bit CPU words. Usually, we refer to an architecture by its CPU word, 32 or 64 bits. s390 uses 32-bit CPU words, no? The Wikipedia article says: "ESA

David Edelsohn added the comment: This has nothing to do with AIX. This conversation should include Charalampos Stratakis, but I don't see him as an option for Nosy. It probably is easy to add a s390 31-bit build to one of the buildbots. -- nosy: -aixto...@gmail.com __

Łukasz Langa added the comment: +1 from me. Whatever few users s390 still has, they can keep using Python 3.9 which is 5 years newer than the latest kernel they can use. Moving forward, s390 will be unambiguously unsupported as we cannot test against this platform. Unless we get a buildbot p

John Paul Adrian Glaubitz added the comment: > I want to make it obvious that the platform has been dropped half a decade > ago. That's a political statement, not a technical one. The change has zero functional impact on the other targets. It just makes the use of Python in a potential s390

[issue43179] Remove 32-bit s390 Linux support (s390-linux-gnu triplet)

John Paul Adrian Glaubitz added the comment: s390 is a 31-bit platform, not a 32-bit platform. I also don't see what this change achieves other than making the use of Python 3.10 on s390 harder. It's not like the removal of support for non-threaded builds which actually saved quite some cod

STINNER Victor added the comment: I created PR 24534 "Drop 32-bit Linux s390 platform support". > We might also want to remove __alpha__, __hppa__, and __m68k__ at a later > point. DEC hasn't been around for a long time. I would prefer to have one ticket per platform support removal. --
