with an ivar that wasn't a bug but was confusing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58311 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-28Don't run the verifier as part of IRgen, this is now down (per module)Daniel Dunbar

2008-10-28Improve our handling of (C++) references within Clang. Specifically:Douglas Gregor
- Do not allow expressions to ever have reference type - Extend Expr::isLvalue to handle more cases where having written a reference into the source implies that the expression is an lvalue (e.g., function calls, C++ casts). - Make GRExprEngine::VisitCall treat the call arguments as lvalues when they are being bound to a reference parameter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58306 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Added compound literal test case.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58279 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Added preliminary support for CompoundLiterals in the static analyzer:Ted Kremenek
- GRExprEngine::VisitCompoundLiteral... (1) visits the initializer list (generating ExplodedNodes) (2) creates a CompoundMemRegion for the literal (3) creates a new state with the bound literal values using GRStateManager::BindCompoundLiteral - GRStateManager::BindCompoundLiteral simply calls StoreManager::BindCompoundLiteral to get a new store and returns a persistent GRState with that store. - BasicStore::BindCompoundLiteral simply returns the same store, as it doesn't handle field sensitivity - RegionStore::BindCompoundLiteral currently fires an assert (pending discussion of how to best implement mappings for CompoundLiteralRegion). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58277 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Improve dependency file support.Daniel Dunbar
- Add support for -MP (phony targets). - Use raw_ostream for output instead of std::string concatenation. - Break long lines in a GCC (4.2) compatible manner. - Output dependents in #included order (to match GCC). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58265 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Refactor the expression class hierarchy for casts. Most importantly:Douglas Gregor
- CastExpr is the root of all casts - ImplicitCastExpr is (still) used for all explicit casts - ExplicitCastExpr is now the root of all *explicit* casts - ExplicitCCastExpr (new name needed!?) is a C-style cast in C or C++ - CXXFunctionalCastExpr inherits from ExplicitCastExpr - CXXNamedCastExpr inherits from ExplicitCastExpr and is the root of all of the C++ named cast expression types (static_cast, dynamic_cast, etc.) - Added classes CXXStaticCastExpr, CXXDynamicCastExpr, CXXReinterpretCastExpr, and CXXConstCastExpr to Also, fixed returned-stack-addr.cpp, which broke once when we fixed reinterpret_cast to diagnose double->int* conversions and again when we eliminated implicit conversions to reference types. The fix is in both testcase and SemaChecking.cpp. Most of this patch is simply support for the renaming. There's very little actual change in semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58264 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27- Move ExprIterator to Stmt.h so that it can be used by classes defined in ↵Ted Kremenek
Stmt.h - Implement child_begin() and child_end() for AsmStmt. Previously these had stub implementations that did not iterate over the input/output operands of an inline assembly statement. - Use ExprIterator for performing iteration over input/output operands. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58261 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Replace common diagnostic with a convenience function.Steve Naroff
This simplifies debug of this particular diagnostic (and removes some code clutter). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58242 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Fix <rdar://problem/6315646> clang on xcode: error: invalid operands to ↵Steve Naroff
binary expression ('id<NSTableViewDelegate>' and 'XCExtendedArrayController *'). There is still a bug here (as the FIXME in the test case indicates). Prior to this patch, the bug would generate an error. Now, we simply do nothing (which is less harmful until we can get it right). The complete bug fix will require changing ASTContext::mergeTypes(), which I'd like to defer for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58241 91177308-0d34-0410-b5e6-96231b3b80d8
