2010-12-19If the initializer is an rvalue and the variable is a const reference,Zhongxing Xu
create a temporary object for it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122161 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
