c++ - How can I make Doxygen aware of CUDA kernel calls? -

i'm trying document project written in cuda c using doxygen. documentation works fine. caller graphs not include kernel calls in gpu_foo<<<1,1>>>().

for example, in simple example:

#include<stdio.h>  /*!  * @brief global hello foo  */ __global__ void global_hello(void){  printf("hello\n");  }   /*!  * @brief cpu hello foo  */ void hello(void){  printf("hello\n"); }  /*!  * @brief main  */ int main(){   hello();   global_hello<<<1,1>>>();  return 0; } 

with corresponding doxyfile:

project_name = test project_numer = 2.1  output_language = english extract_all = yes file_patterns = *.cpp *.h *.c *.cu recursive = no  pdf_hyperlinks = yes use_pdflatex   = yes have_dot = yes call_graph = yes caller_graph = yes 

when looking @ generated documentation call graph looks this:

main -----> hello 

instead of desired:

      ------> global_hello     / main     \       ------> hello 

how can make doxygen aware of cuda kernel calls?

the problem doxygen not know line containing "<<< >>>" function call. not need call graph make distinction between function calls , kernel calls. enough if parser considers kernel normal function calls.

summarizing. there way tell doxygen interpret lines <<<>>> function calls? suggested change internal parser method of doxygen, how should done?

if doxygen doesn't recognize cuda functions, there's not can do:

citing doxygen manual:

note completeness (and correctness) of call graph depends on doxygen code parser not perfect.

and code parser of doxygen not extensible.
