See the companion bugzilla for cross-gcc:
https://bugzilla.redhat.com/show_bug.cgi?id=2281043

The gcc bpf port in gcc 14 and binutils 2.42 is in good shape and usable. 
The GNU toolchain can build the bpf self tests and pass a large number of these tests.

The project wiki page is here:
https://gcc.gnu.org/wiki/BPFBackEnd

The cross-binutils bpf target (and cross-gcc bpf target) has been added to debian and also gentoo.

Would it be possible to add it to Fedora? No additional patches should be needed, aside from the specfile changes if you update to binutils 2.42. Some patches would be needed if you stay at binutils 2.41. (We can provide the list of patches)


Reproducible: Always




Something like the following patch (totally untested!) should work:
