[llvm-dev] 'cl::opt' and range checking

[ORiordan, Martin via llvm-dev]

Hi LLVM-Devs,

The LLVM 'cl::opt' templates are really useful, and provide a lot of flexibility.  But I don't see any support for ranged options.  What I would like is to have an option which is an integer type, and to restrict the set of values provided to a simple upper and lower bound, for example between 10 and 2000.

Is there a way of expressing this with the 'cl::opt' templates, or do I have to explicitly range check the values in my own code and issue a diagnostic or clamp as appropriate?

Thanks,

            MartinO
