* Rework our handling of copy construction of temporaries, which was aDouglas Gregor2010-04-0210-109/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | poor (and wrong) approximation of the actual rules governing when to build a copy and when it can be elided. The correct implementation is actually simpler than the approximation. When we only enumerate constructors as part of initialization (e.g., for direct initialization or when we're copying from a class type or one of its derived classes), we don't create a copy. When we enumerate all conversion functions, we do create a copy. Before, we created some extra copies and missed some others. The new test copy-initialization.cpp shows a case where we missed creating a (required, non-elidable) copy as part of a user-defined conversion, which resulted in a miscompile. This commit also fixes PR6757, where the missing copy made us reject well-formed code in the ternary operator. This commit also cleans up our handling of copy elision in the case where we create an extra copy of a temporary object, which became necessary now that we produce the right copies. The code that seeks to find the temporary object being copied has moved into Expr::getTemporaryObject(); it used to have two different not-quite-the-same implementations, one in Sema and one in CodeGen. Note that we still do not attempt to perform the named return value optimization, so we miss copy elisions for return values and throw expressions. llvm-svn: 100196

Previously, we gave a bland error: 'Nested' does not name a tag member in the specified scope which didn't actually say where we were looking, which was rather horrible when the nested-name-specifier was instantiated. Now, we give something a bit better: error: no class named 'Nested' in 'NoDepBase<T>' llvm-svn: 100060

Improve template instantiation for DependentNameType nodes that represent nested-name-specifiers, by performing tag name lookup and checking the resulting tag appropriately. Fixes PR5681. There is still much testing and cleanup to do in this area. llvm-svn: 100054
