2012-06-16[analyzer] Return an UnknownVal when we try to get the binding for a VLA.Jordan Rose
This happens in C++ mode right at the declaration of a struct VLA; MallocChecker sees a bind and tries to get see if it's an escaping bind. It's likely that our handling of this is still incomplete, but it fixes a crash on valid without disturbing anything else for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158587 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-16[AST/libclang] Fix the selector locations that are reported for aArgyrios Kyrtzidis
method definition that has its '{' attached to the method name without a space. With a method like: -(id)meth{ ..... } the logic in ObjCMethodDecl that determined the selector locations got confused because it was initialized based on an end location for '{' but that end location changed to '}' after the method was finished. Fix this by having an immutable end location for the declarator and for getLocEnd() get the end location from the body itself.

2012-06-16[analyzer] Buffers passed to CGBitmapContextCreate can escape.Jordan Rose
Specifically, although the bitmap context does not take ownership of the buffer (unlike CGBitmapContextCreateWithData), the data buffer can be extracted out of the created CGContextRef. Thus the buffer is not leaked even if its original pointer goes out of scope, as long as - the context escapes, or - it is retrieved via CGBitmapContextGetData and freed. Actually implementing that logic is beyond the current scope of MallocChecker, so for now CGBitmapContextCreate goes on our system function exception list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158579 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-15Warn when a static variable is referenced in a non-static inline function.Jordan Rose
This is explicitly forbidden in C99 6.7.4p3. This is /not/ forbidden in C++, probably because by default file-scope const/constexpr variables have internal linkage, while functions have external linkage. There's also the issue of anonymous namespaces to consider. Nevertheless, there should probably be a similar warning, since the semantics of inlining a function that references a variable with internal linkage do not seem well-defined. <rdar://problem/11577619> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158531 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-15It turns out that implementing the rethrow-on-fallthroughJohn McCall
semantics of a ctor/dtor function-try-block catch handler by pushing a normal cleanup is not just overkill but actually actively wrong when the handler contains an explicit return (which is only legal in a dtor).

2012-06-15PR12717: Clang supports hexadecimal floating-point literals in all languageRichard Smith
modes. For languages other than C99/C11, this isn't quite a conforming extension, and for C++11, it breaks some reasonable code containing user-defined literals. In languages which don't officially have hexfloats, pare back this extension to only apply in cases where the token starts 0x and does not contain an underscore. The extension is still not quite conforming, but it's a lot closer now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158487 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-14This makes SemaCodeComplete.cpp more Doxygen-friendly by changing theJames Dennett
OBJC_AT_KEYWORD_NAME take a string literal argument where previously its second argument was an unquoted token; macro invocations such as OBJC_AT_KEYWORD_NAME(NeedAt,{) confuse Doxygen's parser. While I'm wary of changing code (rather than just comments) to work around Doxygen's limitations, in this case the change makes the code more readable for human beings as well, and the macro derived no benefit from using the preprocessor's stringification operator, as it never has need of the unquoted token. I've also included a couple of trivial drive-by fixes to doc comments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158440 91177308-0d34-0410-b5e6-96231b3b80d8
