Re: Detection of function calls in C and C++ codes

The current C++ built-in parser considers a declaration as a reference.

There is no way except for rewriting the parser.

To whom it may concern,

I need to detect function calls in C and C++. I need to detect calls exclusively (with line numbers), without functions' declarations etc.

 

I've tried to use it like this:

gtags -f fileList.txt

global -r -x exchangeSizes

 

But when I'm trying to parse some C++ codes, I'm encountering problems like this:

 

/projects/p_readex/amt/ProxyApps/FOO/lassen_FOO> /projects/p_readex/amt/libraries/global-6.5.4/global/global -r -x exchangeSizes

exchangeSizes      22 SimulationMPI.cxx void exchangeSizes( MPI_Comm comm,
exchangeSizes      32 SimulationMPI.cxx void exchangeSizes( MPI_Comm comm,
exchangeSizes     319 SimulationMPI.cxx    exchangeSizes( comm, overlapDomains, isFacetNeighbor, recvIsFacetNeighbor);
exchangeSizes     519 SimulationMPI.cxx    exchangeSizes( comm, neighbors, sendSize, recvBufferSize );
exchangeSizes     533 SimulationMPI.cxx    exchangeSizes( comm, neighbors, sendBuffer, recvSizes );

SimulationMPI.cxx:

 31 template<class T>
 32 void exchangeSizes( MPI_Comm comm,
 33                     const std::vector<int> &neighbors,
 34                     const std::vector< std::vector<T> > &sendBuffer,
 35                     std::vector<int> &recvBufferSize);
 36
 37

We can see, that the occurence found in SimulationMPI.cxx file on the line 32 is not a call, but a declaration.

So, is there any way, how to detect only function calls?


Thank you very much.

Best regards,
Martin

P.s.: The parsed project is attached.
