'cl::opt' and range checking
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'
