// This test is intended to check that creating vec<DataT, N> with unsupported

// RUN: %clangxx %fsycl-host-only -fsyntax-only -Xclang -verify -Xclang -verify-ignore-unexpected=note,error %s

// Note: there is one more error being emitted: "requested alignemnt is not a
// power of 2" It happens because in all cases above we weren't able to select
// underlying data type for vec and therefore it screwed up other code realying
// on it. This error message is not they key thing we want to test here and
// that's why it is ok to ignore it.
