<pre>No, the constant folding is happening (post-PTX). You can see an add of
constant 0x4000 (16384). The issue here is that the address arithmetic is now
being done with 64-bit types. This is why you see many more integer arithmetic
ops (64-bit arithmetic using 32-bit instructions), and why ISCADD is not
sufficient here. Unfortunately this is a consequence of using a 64-bit address
space.
I'm closing this out as I don't see any actionable items here. Please feel
free to re-open if you see anything.</pre>
