[PATCH] D156436: [llvm/OptTable] Print options without documentation

Sun Jul 30 20:08:19 PDT 2023

MaskRay added a comment.

I agree that displaying all options will be useful. And with `OptInFC1FFlag`, displaying just the negative option in `--help` will be nice.

lichray has a point that (a) this allows determining whether an option is accepted by a specific version of Clang and (b) without a string like "(Undocumented)", an option without a message can be confused with a preceding option.
