<p>Note that the code generator does not yet fully support large
return values. The specific sizes that are currently supported are
dependent on the target. For integers, on 32-bit targets the limit
is often 64 bits, and on 64-bit targets the limit is often 128 bits.
For aggregate types, the current limits are dependent on the element
types; for example targets are often limited to 2 total integer
elements and 2 total floating-point elements.</p>
