2009-07-14Introduce redecl_iterator, used for iterating over the redeclarations of a ↵Argyrios Kyrtzidis
FunctionDecl or VarDecl. It iterates over all the redeclarations, regardless of the starting point. For example: 1) int f(); 2) int f(); 3) int f(); if you have the (2) FunctionDecl and call redecls_begin/redecls_end to iterate, you'll get this sequence: (2) (1) (3) The motivation to introduce this was that, previously, if (3) was a function definition, and you called getBody() at (2), it would not return it, since getBody() iterated over the previous declarations only, so it would only check (2) and (1). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75604 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Introduce FunctionDecl::getLatestDeclaration() and ↵Argyrios Kyrtzidis
VarDecl::getLatestDeclaration(). For multiple redeclarations they return the last one. Also, add some non const versions of methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75603 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14Fixes for a couple of things:Argyrios Kyrtzidis
- Declaration context of ParmVarDecls (that we got from the Declarator) was not their containing function. - C++ out-of-line method definitions didn't get an access specifier. Both were exposed by a crash when emitting a C++ method to a PCH file (assert at Decl::CheckAccessDeclContext()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75597 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-14Update debug info generation for ObjCObjectPointer changes.Daniel Dunbar
- Previously this would crash on recursive types, and it was also incorrectly stripping off a level of indirection. - I'm not 100% convinced this is all correct, but it should be a monotonic improvment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75582 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Instead of recovering from a wrong invalidation, this patch aims to Zhongxing Xu
invalidate the region correctly. It uses the cast-to type to invalidate the region when available. To avoid invalid cast-to type like 'void*' or 'id', region store now only records non-generic casts of regions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75580 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Add basic checking for passing NULL to CFRetain/CFRelease, since those functionsTed Kremenek
are not explicitly marked as not accepting NULL pointers. This check illustrates how we need more refactoring in the custom-check logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75570 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-13Enhance SimpleSValuator::EvalBinOpNN to recognize the trivial caseTed Kremenek
where we are comparing a symbolic value against itself, regardless of the nature of that symbolic value.

2009-07-10This patch includes a conceptually simple, but very intrusive/pervasive change. Steve Naroff
The idea is to segregate Objective-C "object" pointers from general C pointers (utilizing the recently added ObjCObjectPointerType). The fun starts in Sema::GetTypeForDeclarator(), where "SomeInterface *" is now represented by a single AST node (rather than a PointerType whose Pointee is an ObjCInterfaceType). Since a significant amount of code assumed ObjC object pointers where based on C pointers/structs, this patch is very tedious. It should also explain why it is hard to accomplish this in smaller, self-contained patches. This patch does most of the "heavy lifting" related to moving from PointerType->ObjCObjectPointerType. It doesn't include all potential "cleanups". The good news is additional cleanups can be done later (some are noted in the code). This patch is so large that I didn't want to include any changes that are purely aesthetic. By making the ObjC types truly built-in, they are much easier to work with (and require fewer "hacks"). For example, there is no need for ASTContext::isObjCIdStructType() or ASTContext::isObjCClassStructType()! We believe this change (and the follow-up cleanups) will pay dividends over time. Given the amount of code change, I do expect some fallout from this change (though it does pass all of the clang tests). If you notice any problems, please let us know asap! Thanks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75314 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-10Restructure RegionStoreManager::getSizeInElements() to use a switch statementTed Kremenek
over the types of MemRegions. This allows the compiler to warn us which regions are not handled, and also is a little faster. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75304 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-10Revert r75281 and simply remove the assertion in NewCastRegion thatTed Kremenek
CodeTextRegions can only be casted to FunctionPointer or BlockPointerTypes. This simply isn't true. We can handle bogus operations on CodeTextRegions (e.g, an array access) elsewhere. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75285 91177308-0d34-0410-b5e6-96231b3b80d8
