Question

Peer-hole optimization is a form of :

• A. loop optimization

• B. local optimization

• C. constant folding

• D. data flow analysis

Answer 1

Peephole optimization is an optimization technique performed on a small set of compiler-generated instructions; the small set is known as the peephole or window. Peephole optimization involves changing the small set of instructions to an equivalent set that has better performance

It is a form of optimization that is done on a segment of generated code.
