for convenience, the diff for the noble upload. we'll do a binary copy for the upload to -proposed, because the package needs to reach the security pocket as well.
** Patch added: "dpkg.debdiff" https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/2064539/+attachment/5801859/+files/dpkg.debdiff ** Description changed: Power's Linux ABIs all require an explicit call chain be stored on the call stack frames which are all accessible via the stack pointer. Therefore, having a (soft/simulated) frame pointer does not improve backtraces at all on Power. However, forcing a frame pointer via the -fno-omit-frame-pointer option negatively affects performance for multiple reasons: extra prologue/epilogue overhead and fewer shrink-wrapping opportunities. Given -fno-omit-frame-pointer does not provide any improvements (backtraces or otherwise) and only reduces performance, -fno-omit-frame-pointers should not be used on Power. + + SRU: + + these changes were implemented during the opening of the oracular + series. The very same changes are backported to 24.04 LTS. These only + affect the ppc64el and s390x architectures, for other architectures it's + a no-change upload. + + We didn't see any fallout for these changes during the development on + the oracular series, and therefore don't expect any fallout or + regressions in 24.04 LTS either. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064539 Title: Revert back frame pointers for ppc64el (remove -fno-omit-frame- pointer) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/2064539/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
