// the return value. This could be a perfect case for the 'Returned' attribute.
// However the 'this' type and the return type are transformed in different
// ways, making them bitcast incompatible.
// Example: extern(C): struct Value { this(string) {} string s; }
// return type: { i64, i64 }
// this type: %ldc_github_624.Value*

// (2) The attributes are cleared by some abi implementations
