2009-07-23Remove a bunch of FIXME's related to ObjC type checking.Steve Naroff
- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext. - Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible(). - Tweak several test cases to accommodate the new/improved type checking. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76830 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-23Add constructor used to initialize base/member inFariborz Jahanian
CXXBaseOrMemberInitializer AST node. Needed by its clients to do the initialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76826 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add warning for falling off the end of a function that should return aMike Stump
value. This is on by default, and controlled by -Wreturn-type (-Wmost -Wall). I believe there should be very few false positives, though the most interesting case would be: int() { bar(); } when bar does: bar() { while (1) ; } Here, we assume functions return, unless they are marked with the noreturn attribute. I can envision a fixit note for functions that never return normally that don't have a noreturn attribute to add a noreturn attribute. If anyone spots other false positives, let me know! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76821 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Implement support for out-of-line definitions of the class members of classDouglas Gregor
templates, e.g., template<typename T> struct Outer { struct Inner; }; template<typename T> struct Outer<T>::Inner { // ... }; Implementing this feature required some extensions to ActOnTag, which now takes a set of template parameter lists, and is the precursor to removing the ActOnClassTemplate function from the parser Action interface. The reason for this approach is simple: the parser cannot tell the difference between a class template definition and the definition of a member of a class template; both have template parameter lists, and semantic analysis determines what that template parameter list means. There is still some cleanup to do with ActOnTag and ActOnClassTemplate. This commit provides the basic functionality we need, however. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76820 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Change Preprocessor to keep a copy of LangOptions instead of reference, like ↵Argyrios Kyrtzidis
ASTContext. Now when creating a Preprocessor we can pass it a temporary LangOptions object instead of having to remember to keep it around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76815 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Refactor 'PostStmt' and 'PreStmt' to subclass a common parent 'StmtPoint'.Ted Kremenek
Educate GRExprEngine::VisitGraph() about 'PreStmt'. Mark the constructor of 'PostStmt' to be explicit, preventing implicit conversions and the selection of the wrong 'generateNode' method in GRStmtNodeBuilder. Constify a bunch of arguments, which falls out of the changes to ProgramPoint. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76809 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Add support for registering 'Checker' objects with GRExprEngine.Ted Kremenek
Add a 'previsit' stage (that dispatches to registered Checkers) when evaluating the effects of CallExprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76794 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add new 'Checker' and 'CheckerVisitor' classes, which represent a more powerfulTed Kremenek
interface to plug in domain-specific checker logic than the current GRSimpleAPICheck interface. The new 'Checker' interface can actually generate new nodes, allowing it to modify the state and refine the analysis (which GRSimpleAPIChecks could not). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76793 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-22Add support for 'PreStmt' program points to GRCoreEngine and GRStmtNodeBuilder.Ted Kremenek

2009-07-22Add 'PreStmt' program point. This will be used to represent checking forTed Kremenek
preconditions (in GRExprEngine) before the statement itself is evaluated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76791 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22Restructure ProgramPoint to have the 'Kind' value be its own instanceTed Kremenek
variable. This gives us much more flexibility with defining more ProgramPoints, which is the direction we are heading. The removal of various bit-mangling of pointers also cleans up the logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76721 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-21Fix PR 4594 by refactoring almost all casting logic from GRExprEngine::VisitCastTed Kremenek
to SValuator::EvalCast. In the process, the StoreManagers now use this new cast machinery, and the hack in GRExprEngine::EvalBind to handle implicit casts involving OSAtomicCompareAndSwap and friends has been removed (and replaced with logic closer to the logic specific to those functions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76641 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76532 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-21Change the semantics for Entity.Argyrios Kyrtzidis
Entity can now refer to declarations that are not visible outside the translation unit. It is a wrapper of a pointer union, it's either a Decl* for declarations that don't "cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl. Included is a test case for handling fields across translation units. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76515 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-21Implement the virtual getNextRedeclaration() for ObjCMethodDecl.Argyrios Kyrtzidis
If it's in an ObjCContainerDecl, its "redeclaration" is the method definition in the corresponding ObjCImplDecl. If it's in an ObjCImplDecl, its "redeclaration" is the method in the interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76512 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-21- Introduce ASTContext::getObjCImplementation() and ↵Argyrios Kyrtzidis
ASTContext::setObjCImplementation() which use a DenseMap to associate an interface/category with its implementation (if one exists). - Introduce ObjCInterfaceDecl::get/setImplementation() and ObjCCategoryDecl::get/setImplementation() that use the above methods. - Add a compiler error for when a category is reimplemented. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76508 91177308-0d34-0410-b5e6-96231b3b80d8
