Fedora Decides After All To Allow Default Compiler Flag To Help Debugging/Profiling
The past several months saw much discussion over a proposal to add "-fno-omit-frame-pointer" as a default compiler flag to Fedora Linux that would improve profiling/debugging but with possible performance implications that can vary based on the application/workload. While just over one month ago FESCo rejected that change, they re-voted today and decided after all to allow this change to happen but to ensure that packages can easily opt-out if they find performance regressions. By Fedora 40 they will also re-visit the matter to determine if the benefits and performance costs are justified...
