* **sat mode** or saturation: clamps each element result to a min/max rather than overflows / wraps. allows signed and unsigned clamping for both INT
and FP.
-* **reduce mode**. if used correftly, a mapreduce (or a prefix sum)

* **pred-result** will test the result (CR testing selects a bit of CR and inverts it, just like branch conditional testing) and if the test fails it
is as if the
