Contributions are welcome. Due to the nature of Portage, merging changes could prove difficult, especially as users are expected to only take from this configuration what they find useful. USE flag changes, for example, are likely not to be accepted. New compiler flags however could be, particularly if they give the compiler more freedom to make decisions. Contributions must keep in the philosophy stated in the README. Contributions which override the compiler's better judgement will be rejected.
When creating a PR, the title of the commit should be:
<category>/<package>: <executive summary>
If the PR is to add something to ltoworkarounds.conf, make sure there is a comment next to the relevant lines that explains the encountered error.
If the PR contains a patch that allows an LTO program to build, prefer to keep the patch as a user-patch in the patches directory, incrementing the revision of sys-config/ltoize as necessary.
For all other PRs, it is recommended that you make an issue on the issue tracker first so we can discuss the problem being solved and the approach taken. This repo has been ultimately shaped by this principle, such that the best solution emerges. If you don't want to create an issue, you can also contact me directly through e-mail.
