Branch likely instructions are helpful, when the branch is actually
taken, as the name suggests. The use will however depend on the
number of times. you expect the condition to be satisfied.
That will result in more optimal code and faster code in execution
time as well. as the instruction would have been updated into the
It really depends on your code. if your aim is only code size
reduction, than whatever the case maybe.you may want to use them
liberally , as the code may easily fill in the delay slot.
Hope this helps.
