Theory of Computation and Compilers MCQ - Code Generation And Optimization
Redundant instructions may be discarded during the final stage of compilation by using a simple optimizing technique called peephole optimization. It is a kind of optimization performed over a very small set of instructions in a segment of generated code. The set is called a "peephole" or a "window". It works by recognizing sets of instructions that can be replaced by shorter or faster sets of instructions and it uses some common techniques: Constant folding. So option (C) is correct
