AST: For auto-synthesized ivars give them the location of the related property (previously they had no source location). This allows them to be indexed by libclang. libclang: Make sure synthesized ivars are indexed before the methods that may reference them.

2012-06-08[analyzer] Add experimental "issue hash" to the plist diagnostic.Anna Zaks
CmpRuns.py can be used to compare issues from different analyzer runs. Since it uses the issue line number to unique 2 issues, adding a new line to the beginning of a file makes all issues in the file reported as new. The hash will be an opaque value which could be used (along with the function name) by CmpRuns to identify the same issues. This way, we only fail to identify the same issue from two runs if the function it appears in changes (not perfect, but much better than nothing). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158180 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-07Plug a long standing memory leak in TemplateArgument.Benjamin Kramer
The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158150 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-07[analyzer] Anti-aliasing: different heap allocations do not aliasAnna Zaks
Add a concept of symbolic memory region belonging to heap memory space. When comparing symbolic regions allocated on the heap, assume that they do not alias. Use symbolic heap region to suppress a common false positive pattern in the malloc checker, in code that relies on malloc not returning the memory aliased to other malloc allocations, stack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158136 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-06Add pedantic warning -Wempty-translation-unit (C11 6.9p1).Jordan Rose
In standard C since C89, a 'translation-unit' is syntactically defined to have at least one "external-declaration", which is either a decl or a function definition. In Clang the latter gives us a declaration as well. The tricky bit about this warning is that our predefines can contain external declarations (__builtin_va_list and the 128-bit integer types). Therefore our AST parser now makes sure we have at least one declaration that doesn't come from the predefines buffer. Also, remove bogus warning about empty source files. This doesn't catch source files that only contain comments, and never fired anyway because of our predefines.

2012-06-04Teach format string checking about compile-time CFString constants.Jordan Rose
Within the guts of CheckFormatHandler, the IsObjCLiteral flag was being used in two ways: to see if null bytes were allowed, and to see if the '%@' specifier is allowed.* The former usage has been changed to an explicit test and the latter pushed down to CheckPrintfHandler and renamed ObjCContext, since it applies to CFStrings as well. * This also changes how wide chars are interpreted; in OS X Foundation, the wide character type is 'unichar', a typedef for short, rather than wchar_t. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157968 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-04Add a warning for when an array-to-pointer decay is performed on an arrayRichard Smith
temporary or an array subobject of a class temporary, and the resulting value is used to initialize a pointer which outlives the temporary. Such a pointer is always left dangling after the initialization completes and the array's lifetime ends. In order to detect this situation, this change also adds an LValueClassification of LV_ArrayTemporary for temporaries of array type which aren't subobjects of class temporaries. These occur in C++11 T{...} and GNU C++ (T){...} expressions, when T is an array type. Previously we treated the former as a generic prvalue and the latter as a class temporary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157955 91177308-0d34-0410-b5e6-96231b3b80d8
