# used in the actual operation of the instruction. It is expected
# that these are used only in the flag code.
# Rationale behind the checks: at times, we need to partially update
# the condition code bits in a register. So we read the register even
# in the case when the all the bits will be written, or none of the
# bits will be written. The read predicate checks if any of the bits
