Module ClangFrontend.CContext

Contains current class and current method to be translated as well as local variables, and the cfg, and tenv corresponding to the current file.

    Some (m, _) means that creating pvar should also set m to 1 so that we know whether pvar needs to be destroyed after the current full-expression

    In order to know when to destruct C++ temporaries created in expressions containing conditionals (e.g. to hold the object created by X() in b?foo(X()):goo()), we associate "markers" to each one of them, set to true if and only if the temporary has been created. This is the map associating each such C++ temporary with its marker variable.
