3. For the following code, rearrange the code to use the branch delay slot so the
outcome of the program is not changed and no stall (noop) occurs. Draw an
arrow from the instruction that will be moved to the branch delay slot.
add $7, $8, $9
TARGET: add $4, $2, $3
add $3, $1, $2
BEQ $1, $2, TARGET
(branch delay slot)
And do the same thing again with the following code:
BEQ $1, $2, TARGET
(branch delay slot)
TARGET: add $4, $2, $3
add $3, $1, $2
add $7, $8, $9
