I built all projects that use TableGen (llvm clang, libc, lld, lldb, mlir) for all targets and apart from the Sparc warnings in LLVM that are outstanding (D109712 <https://reviews.llvm.org/D109712>) I only found 2 warnings in MLIR, which are addressed in D110805 <https://reviews.llvm.org/D110805>. Once these outstanding warnings are addressed I think this can be enabled for the whole ecosystem, so I've updated the patch to enable flag for LLVM and sub-projects, if `LLVM_ENABLE_WARNINGS=On`.
