// The following ABI tests are made with nvcc 11.6 does.
//
// The PTX ABI stability is tied to major versions of the PTX ISA
// These tests assume major version 7
//
//
// The following correspondence between types are assumed:
// u<N> - uint<N>_t
// i<N> - int<N>_t
// [T, N] - std::array<T, N>
// &T - T const*
// &mut T - T*

// CHECK: .version 7
