2012-10-11Provide a fixit when taking the address of an unqualified member function.David Blaikie
This only applies if the type has a name. (we could potentially do something crazy with decltype in C++11 to qualify members of unnamed types but that seems excessive) It might be nice to also suggest a fixit for "&this->i", "&foo->i", and "&foo.i" but those expressions produce 'bound' member functions that have a different AST representation & make error recovery a little trickier. Left as future work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165763 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-11-Warc-repeated-use-of-weak: Don't warn on a single read followed by writes.Jordan Rose
This is a "safe" pattern, or at least one that cannot be helped by using a strong local variable. However, if the single read is within a loop, it should /always/ be treated as potentially dangerous. <rdar://problem/12437490> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165719 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-11-Warc-repeated-use-of-weak: Check messages to property accessors as well.Jordan Rose
Previously, [foo weakProp] was not being treated the same as foo.weakProp. Now, for every explicit message send, we check if it's a property access, and if so, if the property is weak. Then for every assignment of a message, we have to do the same thing again. This is a potentially expensive increase because determining whether a method is a property accessor requires searching through the methods it overrides. However, without it -Warc-repeated-use-of-weak will miss cases from people who prefer not to use dot syntax. If this turns out to be too expensive, we can try caching the result somewhere, or even lose precision by not checking superclass methods. The warning is off-by-default, though. <rdar://problem/12407765> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165718 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-11[libclang] Improve AST serialization done by ASTUnit::Save().Argyrios Kyrtzidis
The ASTUnit needs to initialize an ASTWriter at the beginning of parsing to fully handle serialization of a translation unit that imports modules.

2012-10-11Deserialize macro history when we deserialize an identifier that hasDouglas Gregor
macro history. When deserializing macro history, we arrange history such that the macros that have definitions (that haven't been #undef'd) and are visible come at the beginning of the list, which is what the preprocessor and other clients of Preprocessor::getMacroInfo() expect. If additional macro definitions become visible later, they'll be moved toward the front of the list. Note that it's possible to have ambiguities, but we don't diagnose them yet. There is a partially-implemented design decision here that, if a particular identifier has been defined or #undef'd within the translation unit, that definition (or #undef) hides any macro definitions that come from imported modules. There's still a little work to do to ensure that the right #undef'ing happens. Additionally, we'll need to scope the update records for #undefs, so they only kick in when the submodule containing that update record becomes visible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165682 91177308-0d34-0410-b5e6-96231b3b80d8

offsets." Author: Jordan Rose <jordan_rose@apple.com> Date: Wed Oct 10 21:31:21 2012 +0000 [analyzer] Treat fields of unions as having symbolic offsets. This allows only one field to be active at a time in RegionStore. This isn't quite the correct behavior for unions, but it at least would handle the case of "value goes in, value comes out" from the same field. RegionStore currently has a number of places where any access to a union results in UnknownVal being returned. However, it is clearly missing some cases, or the original issue wouldn't have occurred. It is probably now safe to remove those changes, but that's a potentially destabilizing change that should wait for more thorough testing.
