2009-07-20Reuse VarDecl::Init to store the default argument of a ParmVarDecl,Douglas Gregor
reducing the size of ParmVarDecl by one pointer. Also means that we'll properly (de-)serialize default arguments in C++ PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76487 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Update DataflowSolver to handle the case where a successor/predecessor blockTed Kremenek
could be NULL. This allows the solver to handle optimized CFGs where branches can be determined during CFG-construction to be infeasible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76452 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-20Enhance GRBranchNodeBuilderImpl (part of GRCoreEngine) to understand the caseTed Kremenek

2009-07-18Introduce a redecl_iterator in Decl class, so that we can do a "iterate over ↵Argyrios Kyrtzidis

2009-07-17Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methodsTed Kremenek
until Doug Gregor's Type smart pointer code lands (or more discussion occurs). These methods just call the new Type::getAs<XXX> methods, so we still have reduced implementation redundancy. Having explicit getAsXXXType() methods makes it easier to set breakpoints in the debugger. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76193 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Relax the assertion in ASTLocation's ctor: if the decl is not the immediateZhongxing Xu
parent of the stmt, find the immediate parent for the stmt. This is because sometimes we cannot get the immediate decl of the stmt when creating the ASTLocation. We can only get a parent of the stmt. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76159 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-17Replaced Type::getAsLValueReferenceType(), Type::getAsRValueReferenceType(), ↵Ted Kremenek

2009-07-16Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.Ted Kremenek
This method is intended to eventually replace the individual Type::getAsXXXType<> methods. The motivation behind this change is twofold: 1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of them are basically copy-and-paste. 2) By centralizing the implementation of the getAs<Type> logic we can more smoothly move over to Doug Gregor's proposed canonical type smart pointer scheme. Along with this patch: a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>. b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76098 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-16Move RegionStoreManager over to using newTed Kremenek
ValueManager::makeArrayIndex()/convertArrayIndex() methods. This handles yet another crash case when reasoning about array indices of different bitwidth and signedness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75884 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-16Two changes:Ted Kremenek
(1) Moved the SValuator object from GRExprEngine to ValueManager. This allows ValueManager to use the SValuator when creating SVals. (2) Added ValueManager::makeArrayIndex() and ValueManager::convertToArrayIndex(), two SVal creation methods that will help RegionStoreManager always have a consistent set of SVals with the same integer size and type when reasoning about array indices. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75882 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-15Implement the ObjC pseudo built-in types as clang "BuiltinType's". I say ↵Steve Naroff
pseudo built-in types, since Sema still injects a typedef for recognition (i.e. they aren't truly built-ins from a parser perspective). This removes the static data/methods on ObjCObjectPointerType while preserving the nice API (no need to fiddle with ASTContext:-). This patch also adds Type::isObjCBuiltinType(). This should be the last fairly large patch related to recrafting the ObjC type system. The follow-on patches should be fairly small. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75808 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-15More test cases revealed that the logic in StoreManager::InvalidateRegion() ↵Ted Kremenek
needs more finesse when handling the invalidation of pointers. Pointers that were invalidated as integers could later cause problems for clients using them as pointers. It is easier for us to model a symbolic value as a pointer rather than modeling a non-symbolic value as a pointer. This patch causes: - StoreManager::InvalidateRegion() to not used the casted type of a region if it would cause a pointer type to be invalidated as a non-pointer type. - Pushes RegionStore::RetrieveElement() further by handling retrievals from symbolic arrays that have been invalidated. This uses the new SymbolDerived construct that was recently introduced. The result is that the failing test in misc-ps-region-store-x86_64.m now passes. Both misc-ps-region-store-x86_64.m and misc-ps-region-store-i386.m contain a test case that motivated this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75730 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-15Introduced the notion of a "derived symbol" using the class SymbolDerived.Ted Kremenek
SymbolDerived allows us to model symbolic values that are related to other symbols via a region hierarchy. For example, SymbolDerived can be used to model individual values of a symbolic array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75728 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-14Remove -ftraditional option, which gcc doesn't actually support. Make Eli Friedman
using -traditional and -traditional-cpp with clang an error because it's unsupported in clang and causes a significant change in the semantics of the language. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@75690 91177308-0d34-0410-b5e6-96231b3b80d8
