I don't have access to your bugzilla, so I'm assuming you pointed to your own patch and its crc32.c section where you pass hwcap by argument and call it earlier in the stack? If so, I've implemented this approach in this new debdiff, and the PPA has been updated as well :-).
Michael, if you're wondering why the s390_crc32_vx has migrated to crc32.c, it's because the GLibc documentation mentions something about ifunc only working properly if the deported functions are in the same translation unit. In the end, my version of the patch doesn't look that different to Ilya's ;-) ** Patch added: "zlib.debdiff" https://bugs.launchpad.net/ubuntu/+source/zlib/+bug/1932010/+attachment/5517342/+files/zlib.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to zlib in Ubuntu. https://bugs.launchpad.net/bugs/1932010 Title: [21.10 FEAT] zlib CRC32 optimization for s390x Status in Ubuntu on IBM z Systems: In Progress Status in zlib package in Ubuntu: In Progress Bug description: Use SIMD instructions to accelerate the zlib CRC32 implementation.
