2009-08-23Eli points out that we really must diagnose "void* > 0" as an extension. Chris Lattner
Explicitly add it as an EXTENSION instead of an EXTWARN so that it only comes out with -pedantic. Thanks Eli! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79791 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-22Removed -Wundeclared-selector and -Wreadonly-setter-attrs fromFariborz Jahanian
-Wmost group (too noisy). Placed warning on parameter type misatch between methods in sub and super class under -Wsuper-class-method-mismatch (also too noisy). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79745 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-21Remove 'AnalysisContext::setDecl()', as we the Decl associated with anTed Kremenek
AnalysisContext should never change. Along the way, propagate some constness around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79701 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79700 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-21Remove 'SelfRegion' field from both BasicStoreManager and RegionStoreManager.Ted Kremenek
SelfRegion represented the object bound to 'self' (when analyzing Objective-C methods) upon entry to a method. Having this region stored on the side ignores the current stack frame that we might be analyzing (among other things), and is a problem for interprocedural analysis. For RegionStoreManager, the value for SelfRegion is just lazily created. For BasicStoreManager, the value for SelfRegion is bound eagerly to 'self', but no explicit tracking of SelfRegion on the side is made. As part of this change, remove the restriction in BasicStoreManager that we only track ivars for 'self'. This shouldn't actually change anything in terms of precision, and simplifies the logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79694 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Make integer promotions work correctly on PIC16 and other platforms Eli Friedman
where sizeof(short) == sizeof(int). Move UsualArithmeticConversionsType out of Sema, since it was only there as a historical artifact. Patch by Enea Zaffanella. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79412 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Introduce LocInfoType which is a Sema-specific implementation detail.Argyrios Kyrtzidis
This is a Type subclass that can hold a DeclaratorInfo* when we have type source info coming out of a declarator that we want to preserve. This is used only at the "border" of Parser/Sema for passing/getting QualTypes, it does not participate in the type system semantics in any way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79394 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Introduce DeclaratorDecl and pass DeclaratorInfo through the Decl/Sema ↵Argyrios Kyrtzidis
interfaces. DeclaratorDecl contains a DeclaratorInfo* to keep type source info. Subclasses of DeclaratorDecl are FieldDecl, FunctionDecl, and VarDecl. EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo. Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79392 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Introduce DeclaratorInfo and TypeLoc, intended to be used for storing and ↵Argyrios Kyrtzidis
reading source information for types. DeclaratorInfo will contain a flat memory block for source information about a type that came out of a declarator. TypeLoc and its subclasses will be used by clients as wrappers to "traverse" the memory block and read the information. Both DeclaratorInfo and TypeLoc are not utilized in this commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79391 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Renamed ClassProp data member of ObjCImplctSetterGetterRefExprFariborz Jahanian
to InterfaceDecl, as it is unrelated to any property and holds the InterfaceDecl needed for accessing class getter/setter methods using the dot-syntax. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79371 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Renamed ObjCKVCRefExpr to ObjCImplctSetterGetterRefExpr.Fariborz Jahanian
Removed an unnecessary loop to get to setters incoming argument. Added DoxyGen comments. Still more work to do in this area (WIP). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79365 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Change ActOnReturnStmt to not take a FullExprArg. Instead, Sema will wrap ↵Anders Carlsson
the return expr inside a CXXExprWithTemporaries if needed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79342 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79328 91177308-0d34-0410-b5e6-96231b3b80d8

BugReporter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79327 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-18Enhance static analyzer diagnostics by introducing a new 'EnhancedBugReporter'Ted Kremenek
which allows custom checks to register callback creator functions for creating BugReporterVisitor objects. This allows various checks to include diagnostics such as 'assuming value is null' with little extra work. Eventually this API should be refactored to be cleaner and more simple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79302 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-17Initial patch to support definitions of id and Class from headers in ↵David Chisnall
Objective-C code. This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable. The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa. Approved by snaroff. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79248 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79196 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-16Improve the diagnostic emitted when an unused ObjC property getterChris Lattner
is found. Instead of complaining about a generic "unused expr", emit: t.m:7:3: warning: property access result unused - getters should not have side effects While objc property getters *could* have side effects, according to the language best practices, they *shouldn't*. Hopefully the diagnostic now gets this across. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79192 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-16AddInitializerToDecl can't take a FullExprArg. Make it take an ExprArg, and ↵Anders Carlsson
create the CXXExprWithTemporaries before setting the initializer on the VarDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79176 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-16Move builtin call checking out into a separate function, make ↵Anders Carlsson
CheckFunctionCall and CheckBlockCall return bool instead. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79157 91177308-0d34-0410-b5e6-96231b3b80d8
