RE: [cdt-dev] A question about IASTLiteralExpression

I assume that when you say pre-defined constant, you mean a macro. The parser resolves macros before adding the information to the AST. I’ve never tried this, but my guess is that you should be able to find the macro by getting the node location of the literal. It should somehow point to the macro definition for which you can get the name of the macro as you expected.

Subject: [cdt-dev] A question about IASTLiteralExpression




I am using CDT to implement a static analysis tool. I have a question about the class IASTLiteralExpression. For example, if I have a MPI function call MPI_Barrier(MPI_COMM_WORLD), the parameter MPI_COMM_WORLD is a pre-defined constant, and finally it is a IASTLiteralExpression. However, the "value" of this parameter is an address 0x(something), not the string MPI_COMM_WORLD as I expected. Does anybody know how to get the original string?


Thank you very much.
