I've found the code generating the function call in gfc_conv_procedure_call
(trans-expr.cc:7680)

  /* Add the return arguments.  */
  vec_safe_splice (retargs, arglist);

  /* Add the hidden present status for optional+value to the arguments.  */
  vec_safe_splice (retargs, optionalargs);

  /* Add the hidden string length parameters to the arguments.  */
  vec_safe_splice (retargs, stringargs);

  /* We may want to append extra arguments here.  This is used e.g. for
     calls to libgfortran_matmul_??, which need extra information.  */
  vec_safe_splice (retargs, append_args);


We now need the corresponding part on the procedure side.
