Target code generation is the final phase of compiler. Through post code generation, optimization process can be applied on the code, but that can be seen as a part of code generation phase itself. Intermediate code generation in compiler design. Sophisticated compilers typically perform multiple passes over various intermediate forms. •if current value of y and/or z have no next.

R1 = c * d; Among many computational orders, some will require only fewer registers to hold the intermediate results. Therefore, code generator assumes to have unlimited number of memory storage (register) to generate code. Code generation can be considered as the final phase of compilation. Sophisticated compilers typically perform multiple passes over various intermediate forms.
