--- Comment #2 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
michael i am just reviewing the isatables for LOGICAL operations.  two things
struck me:

1. CR0 is apparently an input for OP_CNTZ but not an output, and we have no cr0
in LogicalInputData.

2. i am not seeing any of the LOGICAL operations listed as needing carry in nor
producing carry out.

looking here:

it does not appear that any or them set anything other than CR0 and that is an
output only.
