Compiler peephole

How do you implement peephole optimization?
Common techniques applied in peephole optimization:
1. Null sequences – Delete useless operations
2. Combine operations – Replace several operations with one equivalent
3. Algebraic laws – Use algebraic laws to simplify or reorder instructions
4. Special case instructions – Use instructions designed for special operand cases
What is benefit of peephole optimization?
Peephole optimization in compiler design can improve code efficiency by eliminating redundant or unnecessary code sequences.
This is done by identifying instances where the same computation is performed multiple times or where a computation has no effect on the final result and then removing the redundant instructions._{Mar 24, 2023}.
What is peephole optimization code in C++?
Peephole optimization eliminates unreachable code by removing and recognizing instruction sequences that can never be executed.
It streamlines the program and improves efficiency._{Aug 12, 2023}.
What is the application of peephole?
Peephole optimization in compiler design is used in compiler design to improve the performance of generated machine code.
It involves analyzing a small portion of generated code, typically a few consecutive instructions or a “peephole,” and then applying a series of transformations to optimize the code._{Mar 24, 2023}.
What is the objective of peephole?
The goal of peephole optimization in compiler design is to identify and eliminate redundant or unnecessary code sequences and replace expensive operations with cheaper ones._{Mar 24, 2023}.
Loop Optimization is a machine independent optimization.
Whereas Peephole optimization is a machine dependent optimization technique.
Decreasing the number of instructions in an inner loop improves the running time of a program even if the amount of code outside that loop is increased.

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.

Code optimization that is applied to a small section of the code is known as peephole optimization in compiler design. It is called local optimization because it works by evaluating a small section of the generated code, generally a few instructions, and optimizing them based on some predefined rules.

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.
