Code Optimization: It is used to improve the intermediate code so that the output of the program could run faster and takes less space. There are also other methods, such as whole stage code generation and columnar data layout, that are worth further investigation. Code optimization : Code generator : Lexical analyzer _____ An optimizer compiler . But the main purpose of doing some code-optimization on intermediate code generation is to enhance the portability of the compiler to target processors. So Option A) is more suitable here. In optimization, high-level general programming constructs are replaced by very efficient low-level programming codes. more flexibility is available to the programmer in that he may use all the features of the assembler in conjunction with macros. 1. functions are combined and it is not necessary to create intermediate files as output from the macro-processor and input to the assembler.
