Hi Joseph, I am trying to encode the relationship between Wstrict-aliasing and Wstrict-aliasing= in the .opt files, and the same for Wstrict-overflow and Wstrict-overflow=. However, the parameters of Alias() are taken as strings, so we get "3" and "WARN_STRICT_OVERFLOW_CONDITIONAL". Do you have a suggestion how to handle this?
My next step would be to handle aliases also when internally generating options, so I can add EnabledBy(Wall) to Wstrict-aliasing. Does this sound ok to you? Cheers, Manuel.
