 **Notes and Observations**:
 
+* TODO: imho taking a LUT from a CR isn't useful, therefore `bincrlut` should
+  be dropped and `crbinlog` should be changed to take its LUT argument from a GPR.

 * `ternlogi` is like the existing `xxeval` instruction, except operates on
   GPRs instead of VSRs and doesn't require VSX/VMX.
