Douglas Gregor 0b6a6242ed Rework the way we track which declarations are "used" during ... compilation, and (hopefully) introduce RAII objects for changing the "potentially evaluated" state at all of the necessary places within Sema and Parser. Other changes: - Set the unevaluated/potentially-evaluated context appropriately during template instantiation. - We now recognize three different states while parsing or instantiating expressions: unevaluated, potentially evaluated, and potentially potentially evaluated (for C++'s typeid). - When we're in a potentially potentially-evaluated context, queue up MarkDeclarationReferenced calls in a stack. For C++ typeid expressions that are potentially evaluated, we will play back these MarkDeclarationReferenced calls when we exit the corresponding potentially potentially-evaluated context. - Non-type template arguments are now parsed as constant expressions, so they are not potentially-evaluated. llvm-svn: 73899		2009-06-22 20:57:11 +00:00
