speculable exu stream exu block compute phase operation in the unsigned integer value domain that produces condition codes
native on: all
Unsigned integer square root. Helper operation for software square root implementation.
This operation creates a seed value for Newton-Rapheson, or other, iterative methods.
operands: like Identity [xx:x]
