2013-02-18Ensure that the identifier chains have the most recent declaration after ↵Douglas Gregor
module deserialization. This commit introduces a set of related changes to ensure that the declaration that shows up in the identifier chain after deserializing declarations with a given identifier is, in fact, the most recent declaration. The primary change involves waiting until after we deserialize and wire up redeclaration chains before updating the identifier chains. There is a minor optimization in here to avoid recursively deserializing names as part of looking to see whether top-level declarations for a given name exist. A related change that became suddenly more urgent is to property record a merged declaration when an entity first declared in the current translation unit is later deserialized from a module (that had not been loaded at the time of the original declaration). Since we key off the canonical declaration (which is parsed, not from an AST file) for emitted redeclarations, we simply record this as a merged declaration during AST writing and let the readers merge them. Re-fixes <rdar://problem/13189985>, presumably for good this time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175447 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-18Improve indentation of builder type calls.Daniel Jasper
In builder-type calls, it can be very confusing to just indent parameters from the start of the line. Instead, indent 4 from the correct function call. Before: aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break aaaaaaaaaaaaaa); aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()->aaaaaaaaaaaaaaaa( aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) ->aaaaaaaaaaaaaaaaa(); After: aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break aaaaaaaaaaaaaa); aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa() ->aaaaaaaaaaaaaaaa( aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa) ->aaaaaaaaaaaaaaaaa(); git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175444 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-18Reformat lines if they were "moved around".Daniel Jasper
An unwrapped line can get moved around if there is no newline before it and the previous line was formatted. Example: template<typename T> // Cursor is on this line when hitting "format" T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); } "return .." is the second unwrapped line in this scenario. I does not touch any reformatted region. Thus, the result of formatting is: template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); } After second format (and arguably desired end-result): template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); } This fixes: llvm.org/PR15060. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175440 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-17[CodeGen] tighten objc ivar invariant.load attributionSaleem Abdulrasool
An ivar ofset cannot be marked as invariant load in all cases. The ivar offset is a lazily initialised constant, which is dependent on an objc_msgSend invocation to perform a fixup of the offset. If the load is being performed on a method implemented by the class then this load can safely be marked as an inviarant because a message must have been passed to the class at some point, forcing the ivar offset to be resolved. An additional heuristic that can be used to identify an invariant load would be if the ivar offset base is a parameter to an objc method. However, without the parameters available at hand, this is currently not possible.

2013-02-16Rework the visibility computation algorithm in preparationJohn McCall
for distinguishing type vs. value visibility. The changes to the visibility of explicit specializations are intentional. The change to the "ugly" test case is a consequence of a sensible implementation, and I am happy to argue that this is better behavior. Other changes may or may not be intended; it is quite difficult to divine intent from some of the code I altered. I've left behind a comment which I hope explains the philosophy behind visibility computation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175326 91177308-0d34-0410-b5e6-96231b3b80d8
