Message

SYCL does not support the member access for a volatile qualified vector type. The volatile qualifier was removed. You may need to rewrite the code.

Detailed Help

The SYCL* specification does not provide a volatile qualified version of member access for vector type.

Suggestions to Fix

Review the code and adjust it.

For example, this original CUDA* code:

struct Complex : cuFloatComplex {
  float real() const volatile {
    return x;
  }
};

results in the following migrated SYCL code:

struct Complex : sycl::float2 {
  float real() const volatile {
    /*
    DPCT1052:0: SYCL does not support the member access for a volatile qualified
    vector type. The volatile qualifier was removed. You may need to rewrite the
    code.
    */
    return const_cast<struct Complex *>(this)->x();
  }
};

which is rewritten to:

struct Complex : sycl::float2 {
  float real() const volatile {
    return const_cast<struct Complex *>(this)->x();
  }
};
