2013-04-17Fix off-by-one error in #pragma clang system_header.Jordan Rose
The system_header pragma (from GCC) is implemented using line notes in the source manager. However, a line note's line number specifies the number not for the current line, but for the next line. This was making all line numbers appear off by one after the pragma. Reported by Andy Gibbs, uncovered during r179677. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179709 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-17[analyzer] Don't warn for returning void expressions in void blocks.Jordan Rose
This was slightly tricky because BlockDecls don't currently store an inferred return type.

2013-04-17Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs
VerifyDiagnosticConsumer previously would not check that the diagnostic and its matching directive referenced the same source file. Common practice was to create directives that referenced other files but only by line number, and this led to problems such as when the file containing the directive didn't have enough lines to match the location of the diagnostic in the other file, leading to bizarre file formatting and other oddities. This patch causes VerifyDiagnosticConsumer to match source files as well as line numbers. Therefore, a new syntax is made available for directives, for example: // expected-error@file:line {{diagnostic message}} This extends the @line feature where "file" is the file where the diagnostic is generated. The @line syntax is still available and uses the current file for the diagnostic. "file" can be specified either as a relative or absolute path - although the latter has less usefulness, I think! The #include search paths will be used to locate the file and if it is not found an error will be generated. The new check is not optional: if the directive is in a different file to the diagnostic, the file must be specified. Therefore, a number of test-cases have been updated with regard to this. This closes out PR15613. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179677 91177308-0d34-0410-b5e6-96231b3b80d8

We currently emit an error message when you try to use thread local storage on targets that don't support it and testing C++11 thread locals will trip this. We don't want to xfail the test for all darwin hosts so add a quick hack to check for darwin10 and disable the test based on that. Only checking darwin10 because anything earlier is really old and I don't have a list of what other hosts don't support tls handy.

2013-04-17Use the extra info in global method pool to speed up looking for ObjC ↵Argyrios Kyrtzidis
overridden methods. When we are in a implementation, we check the global method pool whether there were category methods with the same selector. If there were none (common case) we don't need to do lookups for overridden methods again. Note that for an interface method (if we don't encounter its implementation), it is considered that it overrides methods that were declared before it, not for category methods introduced after it. This is tradeoff in favor of performance, since it is expensive to do lookups in case there was a category, and moving the global method pool to ASTContext (so we can check it) would increase complexity. rdar://13508196 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179654 91177308-0d34-0410-b5e6-96231b3b80d8
