Also, it could be a good thing to expand Profile-Guided Optimization (PGO) usage across as many packages as possible. Examples of PGO benchmarks for different software can be found here: https://github.com/zamazan4ik/awesome-pgo#pgo-showcases . Providing more performance would be useful for more packages even before enabling LLVM BOLT optimization. Alexander, here at Fedora, the package maintainers are free to decide the best way to build their packages. There is nothing much the team maintaining LLVM BOLT can do here. If you'd like to see all these package using LLVM BOLT, I suggest that you report a new bugzilla for each of them so that each package maintainer review your suggestion. With that said, I'm reassigning this bug to Clang. > Alexander, here at Fedora, the package maintainers are free to decide the best way to build their packages. I thought about something like discussing this activity as something like an RFC/proposal to FESCo (https://docs.fedoraproject.org/en-US/fesco/) as a possible place to discuss potentially wide changes to the packages. But I know almost nothing about the Fedora internal processes - just heard about FESCo in local Fedora chats, and maybe this question to too "low-level" for FESCo or any other kind of other Fedora committee. > If you'd like to see all these package using LLVM BOLT, I suggest that you report a new bugzilla for each of them so that each package maintainer review your suggestion. Yep. I can do it for many packages (in theory, for *all* C/C++/Rust binaries packages). But probably we need some criteria for creating an issue for a package about PGO. Maybe some existing PGO benchmarks for software? Or any kind of PGO integration in upstream? Need to be discussed.

Before going to FESCo, I suggest to discuss this at https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/ I also recommend to copy the maintainers of each of these packages too. > ... maybe this question to too "low-level" for > FESCo or any other kind of other Fedora committee. No, FESCo does get involved in many low-level discussions. But again, I believe it's important to have an open discussion with the rest of the Fedora community first. This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle. Changing version to 40. This message is a reminder that Fedora Linux 40 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 40 on 2025-05-13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '40'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 40 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component. Fedora Linux 40 entered end-of-life (EOL) status on 2025-05-13. Fedora Linux 40 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed. |
