<p>This means that code must first load the half-precision floating point
value as an i16, then convert it to float with <a
href="#int_convert_from_fp16"><tt>llvm.convert.from.fp16</tt></a>.
Computation can then be performed on the float value (including extending to
double etc). When the value is ready to be stored back to memory, this is
done by converting to float if needed, then converting to i16 with
double etc). To store the value back to memory, it is first converted to
float if needed, then converted to i16 with
