struct llvm::ilist_detail::is_valid_option< Option >

Check whether an option is valid.

The steps for adding and enabling a new ilist option include:

• define the option, ilist_foo, above;
• add new parameters for Bar to ilist_detail::node_options;
• add an extraction meta-function, ilist_detail::extract_foo;
• call extract_foo from ilist_detail::compute_node_options and pass it into ilist_detail::node_options; and
• specialize [is_valid_option<ilist_foo<Bar>>](structllvm%5F1%5F1ilist%5F%5Fdetail%5F1%5F1is%5F%5Fvalid%5F%5Foption.html "Check whether an option is valid.") to inherit from std::true_type to get static assertions passing in simple_ilist and ilist_node.
