2012-06-08Warn in ObjC++ when an 'auto' variable deduces type 'id'.Jordan Rose
This could happen for cases like this: - (NSArray *)getAllNames:(NSArray *)images { NSMutableArray *results = [NSMutableArray array]; for (auto img in images) { [results addObject:img.name]; } return results; } Here the property access will fail because 'img' has type 'id', rather than, say, NSImage. This warning will not fire in templated code, since the 'id' could have come from a template parameter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158239 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-08Disallow using ObjC literals in direct comparisons (== and friends).Jordan Rose
Objective-C literals conceptually always create new objects, but may be optimized by the compiler or runtime (constant folding, singletons, etc). Comparing addresses of these objects is relying on this optimization behavior, which is really an implementation detail. In the case of == and !=, offer a fixit to a call to -isEqual:, if the method is available. This fixit is directly on the error so that it is automatically applied. Most of the time, this is really a newbie mistake, hence the fixit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158230 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.

unused private fields of classes that are fully defined in the current translation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158054 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

2012-05-30Disable -Wunique-enum for anonymous enums.David Blaikie
This is a large class of false positives where anonymous enums are used to declare constants (see Clang's Diagnostics.h for example). A small number of true positives could probably be found in this bucket by still warning if the anonymous enum is used in a declarator (enum { ... } x;) but so far we don't believe this to be a source of significant benefit so I haven't bothered to preserve those cases.

2012-05-26In response to some discussions on IRC, tweak the wording of the newRichard Smith
-Wsometimes-uninitialized diagnostics to make it clearer that the cause of the issue may be a condition which must always evaluate to true or false, rather than an uninitialized variable. To emphasize this, add a new note with a fixit which removes the impossible condition or replaces it with a constant. Also, downgrade the diagnostic from -Wsometimes-uninitialized to -Wconditional-uninitialized when it applies to a range-based for loop, since the condition is not written explicitly in the code in that case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157511 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-25Split a chunk of -Wconditional-uninitialized warnings out into a separate flag,Richard Smith
-Wsometimes-uninitialized. This detects cases where an explicitly-written branch inevitably leads to an uninitialized variable use (so either the branch is dead code or there is an uninitialized use bug). This chunk of warnings tentatively lives within -Wuninitialized, in order to give it more visibility to existing Clang users. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157458 91177308-0d34-0410-b5e6-96231b3b80d8
