Yes, I tried. But getRawSignature gave me an empty string.

 

Thanks,

Did you try getRawSignature on the IASTLiteralExpression?

Subject: Re: [cdt-dev] A question about IASTLiteralExpression

 

Go back to my original problem: I tried to traverse the AST of an MPI program and recognized all barrier function calls and their communicators. The barrier function has the form:

int MPI_Barrier(MPI_Comm comm). The MPI_Comm type is defined in mpi.h . A typical use of this barrier function is like MPI_Barrier(MPI_COMM_WORLD), and the communicator MPI_COMM_WORLD is a pre-defined object with type MPI_Comm. I don't think MPI_COMM_WORLD is a macro.

 

When I looked into the AST, the MPI_COMM_WORLD is a IASTLiteralExpression, and its value() is a char array "0x44000000". It really confused me. I am wondering whether I can get the String "MPI_COMM_WORLD" in some way?

 

Thanks,

 

Yuan
