MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Peephole optimization is a technique for locally improving the target code which is done by examining a sliding window of target instructions and replacing the instruction sequences within the peephole by shorter or faster sequences wherever possible. Constant folding is a peephole optimization.

Detailed explanation-2: -Peephole optimization is a type of code Optimization performed on a small part of the code. It is performed on a very small set of instructions in a segment of code. The small set of instructions or small part of code on which peephole optimization is performed is known as peephole or window.

Detailed explanation-3: -Constant folding is an optimization technique that eliminates expressions that calculate a value that can already be determined before code execution. These are typically calculations that only reference constant values or expressions that reference variables whose values are constant.

Detailed explanation-4: -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.

Detailed explanation-5: -The main objective of peephole optimization is: To improve performance. To reduce memory footprint.
