Generation of intermediate code based on an abstract machine model is useful in compilers because:

It makes implementation of lexical and syntax analysis easier

Syntax translations are easier for intermediate code generation

It is difficult to generate executable code from high level language program.

It enhances the portability of the compiler system program

Generation of intermediate code based on an abstract machine model is useful in compilers because:
A variable x is said to be live at a statement Si in a program if the following three conditions hold simultaneously:i. There exists a statement Sj that uses xii.
