Seems clang-18.1.8-r6 is failing for me. I have a bootstrapped clang. The failure seems to be at clang-tblgen.

gonna need emerge --info and a full build.log
Created attachment 911725 [details] emerge --info
Created attachment 911726 [details] clang-18.1.8-r6 build.log
Same issue. I believe this version mismatch is the fatal issue, as in OP sample logs. ** ld.lld: error: utils/TableGen/CMakeFiles/clang-tblgen.dir/ClangAttrEmitter.cpp.o: Invalid attribute group entry (Producer: 'LLVM19.1.4' Reader: 'LLVM 18.1.8') clang++: error: linker command failed with exit code 1 (use -v to see invocation

As suggested by Matt, use LLVM_CMAKE_DIR instead so that Clang finds the right version of LLVM to build against without any sort of nonsense messing with build tooling.
