Thanks for the advice!

I pushed updated llvm, clang, libcxx, libcxxabi, compiler-rt,
libunwind, and lld packages.

Done.

The related paths are:
usr/share/doc/llvm              : llvm package (--exclude=html, --exclude=ocaml-html)
usr/share/doc/llvm/html/        : llvm-doc package
usr/share/doc/LLVM/polly/html/  : polly-doc package
usr/share/doc/llvm/ocaml-html/  : ocaml-llvm-doc package
usr/share/doc/LLVM/llvm/html/   : PKG_IGNORE

so I added --exclude=polly to llvm_CONTENTS and
replaced usr/share/doc/llvm with usr/share/doc/llvm/README.txt.

Done except for providing myst_parser package.

Done.

I ran llvm test and found it hangs around 90% progress.
I'll look into the issue.
