Description David Carlos Manuelda 2022-03-04 12:52:43 UTC

Since some time I am modifying the rust ebuild to allow the posibility to link with llvm-libunwind instead of gcc_s when compiling rust with clang/libcxx/compiler-rt combination.

I've spotted no problems over at least 3 version so I'm sharing it here seeking it to be included mainstream.

Will attach the ebuild diff since it needs only little changes.

Reproducible: Always
