<br>
Just curious, *NOT* review. <br>
o. What's the advantage of this transformation if the costs
(say, in term of latency) between <br>
fadd/fsub and fmpy is negligible?<br>
<br>
o. As far as I can understand, this change only catch log2(0.5 x
x) => log2x - 1. <br>
Is it able to figure out a FP value is negative-power-of-2 (to
make this transformation more general)?<br>
<br>
Thanks<br>
