DPCT1009

Message

SYCL reports errors using exceptions and does not use error codes. Please replace the "get_error_string_dummy(…)" with a real error-handling function.

Detailed Help

SYCL* uses exceptions to report errors and does not use error codes. The original code tries to get a string message through the error code, while SYCL does not require such functionality.

To indicate that the code needs to be updated, a warning string is inserted.

Suggestions to Fix

You may need to rewrite this code.

For example, this original CUDA* code:

void foo() {
  float *f;
  cudaError_t err = cudaMalloc(&f, 4);
  printf("%s\n", cudaGetErrorString(err));
}

results in the following migrated SYCL code:

void foo() try {
  float *f;
  dpct::err0 err = DPCT_CHECK_ERROR(
      f = (float *)sycl::malloc_device(4, dpct::get_in_order_queue()));
  /*
  DPCT1009:1: SYCL uses exceptions to report errors and does not use the error
  codes. The original code was commented out and a warning string was inserted.
  You need to rewrite this code.
  */
  printf("%s\n", dpct::get_error_string_dummy(err));
}
catch (sycl::exception const &exc) {
  std::cerr <<exc.what() << "Exception caught at file." << __FILE__
            << ", line:" << __LINE__ << std:endl;
  std::exit(1);
}

which needs to be rewritten to:

void foo() {
  float *f;
  try {
    f = (float *)sycl::malloc_device(4, dpct::get_in_order_queue())
  } catch (sycl::exception const &e) {
    std::cerr << e.what() << std::endl;
  }
}
