Hello again! It seems that the system failed to extract text from my previous post. This is my first time using a mailing list, so please excuse me for my mistakes. Here are the original contents of that post:
Hello, > > I’ve been trying to do some code generation using clang (not libclang), > and want to find out if a class can be copy constructed. > > I’ve tried testing if the copy constructor is deleted, but this does not > work well with templates. For example, I have a class that contains a > std::vector<std::unique_ptr>, whose copy constructor will apparently fail > to instantiate, but doesn’t cause the copy constructors of std::vector or > my class to be marked as deleted. Also, isInvalidDecl() returns false, > which (I think) means that the compiler didn’t even attempt to instantiate > the constructor as it has never been used. > > I believe that my best bet is to try to manually check if the constructor > can instantiate. I’ve looked at clang::Sema, but was overwhelmed by the > large amount of functions. I also noticed that a lot of these functions > seem to have side effects, which is undesired since I do not want this > check to cause other parts of the code to not compile. > > Am I on the right path? If so, which functions in clang::Sema should I > use, and how? If not, is there a better way? > > Thank you very much. >
