COMPUTE
COND specifies the condition to test. If no condition is specified in the
instruction, COND is the true condition, and the return is always
executed. J determines whether the return is delayed or non-delayed.
E specifies whether or not an ELSE clause is used.
The COMPUTE field defines the compute operation to be performed; this
is a NOP if no compute operation is specified in the instruction.
LR specifies whether or not the loop reentry modifier is specified.
