2010-12-22Always blast through no-op casts when getting expr SVals.Zhongxing Xu
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122390 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-22After inlining the CXXConstructExpr, bind the temporary object region to it.Zhongxing Xu
This change is necessary when the variable is a const reference and we need the l-value of the construct expr. After that, when binding the variable, recover the lazy compound value when the variable is not a reference. In Environment, use the value of a no-op cast expression when it has one. Otherwise, blast-through it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122388 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-16Start migration of static analyzer to using theTed Kremenek
implicit lvalue-to-rvalue casts that John McCall recently introduced. This causes a whole bunch of logic in the analyzer for handling lvalues to vanish. It does, however, raise a few issues in the analyzer w.r.t to modeling various constructs (e.g., field accesses to compound literals). The .c/.m analysis test cases that fail are due to a missing lvalue-to-rvalue cast that will get introduced into the AST. The .cpp failures were more than I could investigate in one go, and the patch was already getting huge. I have XFAILED some of these tests, and they should obviously be further investigated. Some highlights of this patch include: - CFG no longer requires an lvalue bit for CFGElements - StackFrameContext doesn't need an 'asLValue' flag - The "VisitLValue" path from GRExprEngine has been eliminated. Besides the test case failures (XFAILed), there are surely other bugs that are fallout from this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121960 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10It's kindof silly that ExtQuals has an ASTContext&, and we can use thatJohn McCall
space better. Remove this reference. To make that work, change some APIs (most importantly, getDesugaredType()) to take an ASTContext& if they need to return a QualType. Simultaneously, diminish the need to return a QualType by introducing some useful APIs on SplitQualType, which is just a std::pair<const Type *, Qualifiers>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121478 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-04More anonymous struct/union redesign. This one deals with anonymous field ↵Francois Pichet
used in a constructor initializer list: struct X { X() : au_i1(123) {} union { int au_i1; float au_f1; }; }; clang will now deal with au_i1 explicitly as an IndirectFieldDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120900 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-04Although we currently have explicit lvalue-to-rvalue conversions, they'reJohn McCall
not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120890 91177308-0d34-0410-b5e6-96231b3b80d8
