| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 121960

| | | | | | | | | | | | | | | | 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. llvm-svn: 120900
* Although we currently have explicit lvalue-to-rvalue conversions, they'reJohn McCall2010-12-041-2/+19
| | | | | | | | | | | | | | | | | | | 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. llvm-svn: 120890

* Revert r118991.Zhongxing Xu2010-11-141-8/+1
| | | | | | | | | Elidable CXXConstructExpr should inhibit calling destructor for temporary that is copied, not the one created.
