It can be handy to have all information about options gathered in a single place to provide an overview of all supported options. This patch allows the following: def Options : OptionList<[ (switch_option "E", (help "Help string")), (alias_option "quiet", "q") ... ]>; Tool-specific option properties (like 'append_cmd') have (obviously) no meaning in this context, so the only properties that are allowed are 'help' and 'required'. See usage example in examples/Clang.td. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51754 91177308-0d34-0410-b5e6-96231b3b80d8
