Message
SYCL uses exceptions to report errors and does not use the error codes. The call was replaced with 0. You need to rewrite this code.
Detailed Help
SYCL* uses exceptions to report errors and does not use error codes. The original code tries to get an error code, while SYCL does not require such functionality. The call was replaced with 0.
Suggestions to Fix
You may need to rewrite this code.
For example, this original CUDA* code:
__global__ void kernel() {
...
}
void foo() {
kernel<<<1, 1>>>();
cudaDeviceSynchronize();
cudaError_t err = cudaGetLastError();
printf("%d\n", err);
}results in the following migrated SYCL code:
void kernel() {
...
}
void foo() {
dpct::get_default_queue().parallel_for(
sycl::nd_range<3>(sycl::range<3>(1, 1, 1), sycl::range<3>(1, 1, 1)),
[=](sycl::nd_item<3> item_ct1) {
kernel();
});
dpct::get_current_device().queues_wait_and_throw();
/*
DPCT1010:0: SYCL uses exceptions to report errors and does not use the error

*/
int err = 0;
printf("%d\n", err);
}which is rewritten to:
void kernel() {
...
}
void foo() {
try {
dpct::get_default_queue().parallel_for(
sycl::nd_range<3>(sycl::range<3>(1, 1, 1), sycl::range<3>(1, 1, 1)),
[=](sycl::nd_item<3> item_ct1) {
kernel();
});
dpct::get_current_device().queues_wait_and_throw();
} catch (sycl::exception const &e) {
std::cerr << e.what() << std::endl;
}
}
