2012-05-01Remove ref/value inconsistency in redecl_iterator.David Blaikie
Similar to r155808 - this mistake has been made in a few iterators. Based on Chandler Carruth's feedback to r155808 I added an implicit conversion to Decl* to ease adoption/usage. Useful for the pointer comparison, but not the dyn_cast (due to template argument deduction causing the conversion not to be used) - there for future convenience, though. This idiom (op T* for iterators) seems to be fairly idiomatic within the LLVM codebase & I'll likely add it as I fix up the other iterators here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155869 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30Remove -Wc++98-compat warning for an outrageously-rare circumstance of 'this'Richard Smith
being used in an exception specification in a way which isn't otherwise ill-formed in C++98: this warning also incorrectly triggered on uses of 'this' inside thread-safety attributes, and the mechanism required to tell these cases apart is more complex than can be justified by the (minimal) value of this part of -Wc++98-compat. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@155857 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30Fix PR12378: provide conversion warnings on default args of function templatesDavid Blaikie
Apparently we weren't checking default arguments when they were instantiated. This adds the check, fixes the lack of instantiation caching (which seems like it was mostly implemented but just missed the last step), and avoids implementing non-dependent default args (for non-dependent parameter types) as uninstantiated default arguments (so that we don't warn once for every instantiation when it's not instantiation dependent).
