Justin Bogner f66fc53bc7 Support: Fix option handling when using cl::Required with aliasopt ... Until now, attempting to create an alias of a required option would complain if the user supplied the alias, because the required option didn't have a value. Similarly, if you said the alias was required, then using the base option would complain that the alias wasn't supplied. Lastly, if you put required on both, *neither* option would work. By changning alias to overload addOccurrence and setting cl::Required on the original option, we can get this to behave in a more useful way. I've also added a test and updated a user that was getting this wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212986 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-14 20:53:57 +00:00
