* MS ABI: Mangle lambdasDavid Majnemer2014-03-052-1/+50
| | | | | | | | | | | | | | | | | Use a scheme inspired by the Itanium ABI to properly implement the mangling of lambdas. N.B. The incredibly astute observer will notice that we do not generate external names that are identical, or even compatible with, MSVC. This is fine because they don't generate names that they can use across translation units. Technically, we can generate any name we'd like so long as that name wouldn't conflict with any other and would be stable across translation units. This fixes PR15512. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202962 91177308-0d34-0410-b5e6-96231b3b80d8

* [-cxx-abi microsoft] Implement local manglings accuratelyDavid Majnemer2014-03-0518-202/+385
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The MSVC ABI appears to mangle the lexical scope into the names of statics. Specifically, a counter is incremented whenever a scope is entered where things can be declared in such a way that an ambiguity can arise. For example, a class scope inside of a class scope doesn't do anything interesting because the nested class cannot collide with another nested class. There are problems with this scheme: - It is unreliable. The counter is only incremented when a previously never encountered scope is entered. There are cases where this will cause ambiguity amongst declarations that have the same name where one was introduced in a deep scope while the other was introduced right after in the previous lexical scope. - It is wasteful. Statements like: {{{{{{{ static int foo = a; }}}}}}} will make the mangling of "foo" larger than it need be because the scope counter has been incremented many times. Because of these problems, and practical implementation concerns. We choose not to implement this scheme if the local static or local type isn't visible. The mangling of these declarations will look very similar but the numbering will make far more sense, this scheme is lifted from the Itanium ABI implementation.

* Adjust logic for 'objc_protocol_requires_explicit_implementation' for ↵Ted Kremenek2014-03-052-10/+92
| | | | | | | | | | | | | | | | | | | | | | | | inherited protocols and protocols already conformed in the class hierarchy. Per more discussion, 'objc_protocol_requires_explicit_implementation' is refinement that it mainly adds that requirement that a protocol must be explicitly satisfied at the moment the first class in the class hierarchy conforms to it. Any subclasses that also conform to that protocol, either directly or via conforming to a protocol that inherits that protocol, do not need to re-implement that protocol. Doing this requires first doing a pass on the super class hierarchy, gathering the set of protocols conformed to by the super classes, and then culling those out when determining conformance. This two-pass algorithm could be generalized for all protocol checking, and could possibly be a performance win in some cases. For now we restrict this change to protocols with this attribute to isolate the change in logic (especially as the design continues to evolve). This change needs to be adjusted for properties as well; this only impacts methods right now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@202948 91177308-0d34-0410-b5e6-96231b3b80d8
