[llvm-dev] llvm::cl::opt and enums

[Martin J. O'Riordan via llvm-dev]

I have to follow up to this, and say thanks very much to you Renato.

 

Your recommended solution not only works perfectly, it is also very elegant and I can use meaningful words for the options instead of having to remember the enumerate values.  It is also far safer, because it rejects invalid values.

 

Thanks again,

Try something similar to this:
