Introduce a new subclass of ConstantData which represents a blob of data that gets emitted to the .o file, stored in a reasonable native format. I think it would be fine to limit this to only representing arrays of primitive types (e.g. array of float, array of bytes, etc) since this keeps the API to the type simple (the type models an array, so it should have array element members only), and things that want to get the elements of the array out can have them returned as ConstantInt’s (or whatever). I’d name this something like “ConstantArrayBlob”.</div></div></div></blockquote><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><div class="">What's the relationship between ConstantDataArray and ConstantArray?</div></div></div></div></div></div></blockquote><div><br class=""></div><div>Ah, it looks like ConstantDataArray is exactly what I was advocating for.
