<br>
I haven’t been able to come up with a test case that uses the low part of MUL_LOHI, even with Ben’s suggestion.<br>
<br>
The questions now are:<br>
1. Do we leave the code as is and wait for it to fail?<br>
or<br>
2. Do we fix the mask as I think Ben, You, and I agree that this is wrong?<br>
<br>
I would prefer #2, though #1 would give us a test case when it eventually fails!</div></blockquote></div><br>No, we should do #2... I'm just really frustrated that we have tons of logic here and no way to test it. =[ That is kind of terrible in general.</div>
