commit: e802488062f680f9a5ffe2a2ccb3bbefc3a8adb5 Author: Sam James <sam <AT> gentoo <DOT> org> AuthorDate: Mon May 6 17:30:21 2024 +0000 Commit: Sam James <sam <AT> gentoo <DOT> org> CommitDate: Wed Aug 7 02:52:39 2024 +0000 URL: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e8024880
sys-devel/bpf-toolchain: new package, add 14.2.0 Heavily inspired by, and based on, dev-util/mingw64-toolchain. This provides the bpf-unknown-none toolchain for use with DTrace (to be packaged) and systemd. Users may wish to use crossdev if they want to customise their toolchain - this is "just" a convenience option for e.g. aforementioned ebuilds to depend on and have things Just Work.
