[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
Some code optimizations are carried out on the intermediate code because
|
|
they enhance the portability of the compiler to other target processors
|
|
|
program analysis is more accurate on intermediate code than on machine code
|
|
|
the information from dataflow analysis cannot otherwise be used for optimization
|
|
|
the information from the front end cannot otherwise be used for optimization
|
Explanation:
Detailed explanation-1: -Machine-independent optimization phase tries to improve the intermediate code to obtain a better output.
Detailed explanation-2: -Code optimization is a program modification strategy that endeavours to enhance the intermediate code, so a program utilises the least potential memory, minimises its CPU time and offers high speed.
