Hello Liming, This series confuses me. The existing CLANGxx toolchains already use GenFw and ELF to PE/COFF conversion, so the name CLANG8ELF is misleading. Also, it seems that the primary difference is using LLD instead of GNU ld, but this has nothing to do with the Clang version. What is the benefit of using LLD over GNU ld? It seems we are working around various incompatibilities, and I think this is only justified if LLD has some benefit over GNU ld.
