[flang-commits] [clang] [flang] [flang][Driver] Accept (and ignore) some gfortran-specific options (PR #165579)

As nobody objected to the RFC, I think it is okay to follow clang doing this. Tentatively LGTM.

Personally I would only really accept this as a warning for advisory flags where the expectation isn't for the the compiler to definately do as it is advised. Something like "unroll-all-loops" sounds like something that shouldn't be optional for the compiler and so I would prefer to generate an error.

But in this particular case we are following clang's long established example so I guess it is okay.

Please don't merge immediately in case having an approval on this nudges more people to look at the RFC. Perhaps waiting approximately a week would be sensible.
