We'll get there. There are some other SPARC-related clang bugs that need to be squashed first. We have made quite some improvements and it's actually maintained by the community. Of course, we don't have a commercial backer but that shouldn't be necessary for open source to work.
I meant there is no point for Naresh to do it as part of his build testing with tuxmake. If someone else gets it working, they can tell Naresh to try again, but until then, I'd limit clang regression testing to x86, arm, powerpc, s390, mips, riscv and arc.
It's definitely a useful report as I haven't done any tests in this regard yet and we're certainly interested in getting this to work. We previously had Nick give a session on building the kernel with clang in our monthly m68k meeting [1] and he said, they are interested in supporting as many architectures as possible in their efforts.
