Boris,
Thanks for taking the time to try to repro, and the report. Just
curious, which clang are you using? Is it from your distro? If you
have `llc` installed, can you send me the output of `llc --version`?
The reason I ask is; unlike GCC, Clang ships with all non-experimental
backends on by default, and relies on `--target=<triple>` when cross
compiling. You can disable backends when configuring a build of LLVM,
but it's frowned upon for distributions to do so (I do it locally to
speed up development). The above error is indicating that LLVM was
configured to not have RISCV support.
The RISCV backend only recently became a non-experimental (as in on by
default) backend a couple of releases ago, so either you have an old
clang that was intentionally built without experimental backends
(solution: use newer clang, where it should be on by default), or your
distro has disabled the backend (solution: encourage the package
maintainer to fix that), (or you configured LLVM yourself and didn't
enable RISCV).
Either way, you can ignore this report. Known issue with further
discussion here: https://github.com/ClangBuiltLinux/linux/issues/1220.
Happy holidays+new year.

Boris,
Thanks for taking the time to try to repro, and the report. Just
curious, which clang are you using? Is it from your distro? If you
have `llc` installed, can you send me the output of `llc --version`?
The reason I ask is; unlike GCC, Clang ships with all non-experimental
backends on by default, and relies on `--target=<triple>` when cross
compiling. You can disable backends when configuring a build of LLVM,
but it's frowned upon for distributions to do so (I do it locally to
speed up development). The above error is indicating that LLVM was
configured to not have RISCV support.
The RISCV backend only recently became a non-experimental (as in on by
default) backend a couple of releases ago, so either you have an old
clang that was intentionally built without experimental backends
(solution: use newer clang, where it should be on by default), or your
distro has disabled the backend (solution: encourage the package
maintainer to fix that), (or you configured LLVM yourself and didn't
enable RISCV).
Either way, you can ignore this report. Known issue with further
discussion here: https://github.com/ClangBuiltLinux/linux/issues/1220.
Happy holidays+new year.

I just did the steps outlined above, in the mail. Look for "reproduce
(this is a W=1 build):" above. I guess that make.cross script needs to
be fixed to do the --target thing, I haven't looked.
clang is downloaded by the script, just do the steps and you'll see:
