2010-12-15Test that all of the relevant types properly compute the "containsDouglas Gregor
unexpanded parameter pack" bit and that the recursive AST visitor can then find those unexpanded parameter packs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121899 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-15Introduce a RecursiveASTVisitor subclass that finds all unexpandedDouglas Gregor
parameter packs within a statement, type, etc. Use this visitor to provide improved diagnostics for the presence of unexpanded parameter packs in a full expression, base type, declaration type, etc., by highlighting the unexpanded parameter packs and providing their names, e.g., test/CXX/temp/temp.decls/temp.variadic/p5.cpp:28:85: error: declaration type contains unexpanded parameter packs 'VeryInnerTypes', 'OuterTypes', ... ...VeryInnerTypes, OuterTypes>, pair<InnerTypes, OuterTypes> > types; ~~~~~~~~~~~~~~ ~~~~~~~~~~ ~~~~~~~~~~ ~~~~~~~~~~ ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121883 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-15Move the work-in-progress implementation of variadic templates to its own ↵Douglas Gregor
file in Sema. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121869 91177308-0d34-0410-b5e6-96231b3b80d8
