I enabled USE=default-lld and installed sys-devel/clang (17.0.6, current stable one). This automatically installed sys-devel/lld-17.0.6:17 (current stable one). After that I installed =sys-devel/clang-18* (testing version). Expectation: clang works Reality: if LTO or LLVM bitcode is used, clang fails with: ld.lld: error: utils/prepare-builtins/CMakeFiles/prepare-builtins.dir/prepare-builtins.cpp.o: Unknown attribute kind (91) (Producer: 'LLVM18.1.2' Reader: 'LLVM 17.0.6') (LLVM bitcode is backwards compatible. It is however not forward compatible) Proposal: in sys-devel/clang-common setup dependency on >=sys-devel/lld-{PV}
Thanks for the report!
