Suggestions to Fix

For example, this original CUDA* code:

void foo() {
  float *f;
  cudaError_t err = cudaMalloc(&f, 4);
  if (err == cudaErrorMemoryAllocation) {
    std::cerr << "cudaErrorMemoryAllocation" << std::endl;
  }
}

results in the following migrated SYCL* code:

void foo() {
  float *f;
  int err = (f = (float *)sycl::malloc_device(4, dpct::get_default_queue()), 0);
  /*
  DPCT1002:1: Special case error handling if-stmt was detected. You may need to
  rewrite this code.
  */
  if (err == 2) {
    std::cerr << "cudaErrorMemoryAllocation" << std::endl;
  }
}

which is rewritten to:

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