6.32 [10] <§6.6> {Ex. 6.31} The solution to Exercise 6.31 should involve the execution

of fewer instructions than would be required using conditional branches.

Sometimes, however, rewriting code to use movn and movz rather than conditional

branches doesn’t reduce the number of instructions executed. Nonetheless, even

if the use of movn and movz doesn’t reduce the number of instructions executed,

it can still make the program faster if it is being executed on a pipelined datapath.

Explain why.
