GATE | GATE-CS-2014-(Set-3) | Question 65

One of the purposes of using intermediate code in compilers is to
(A) make parsing and semantic analysis simpler.
(B) improve error recovery and error reporting.
(C) increase the chances of reusing the machine-independent code optimizer in other compilers.
(D) improve the register allocation.

Answer: (C)
Explanation: After semantic Analysis, the code is converted into intermediate code which is platform(OS + hardware) independent, the advantage of converting into intermediate code is to improve the performance of code generation and to increase the chances of reusing the machine-independent code optimizer in other compilers.
So, option (C) is correct.
