make parsing and semantic analysis simpler.
improve error recovery and error reporting.
increase the chances of reusing the machine - independent code optimizer in other compilers.
improve the register allocation.

Answer 1

The correct answer is make parsing and semantic analysis simpler.

Key Points

Intermediate code is used in compilers as a bridge between the source code and machine code.
It simplifies parsing and semantic analysis by providing an abstract representation of the source code.
This abstraction helps in isolating the machine-dependent and machine-independent parts of the compilation process.
By using intermediate code, the compiler can perform optimizations more effectively and can target multiple machine architectures.
Examples of intermediate code forms include Three-Address Code (TAC), Static Single Assignment (SSA), and others.

Additional Information

Intermediate code can be more easily manipulated by different phases of the compiler than the original source code.
It provides a uniform structure that can be used to implement various optimizations and transformations.
Using intermediate code helps in separating the concerns of front-end and back-end compiler development.
It can be reused across different compilers, which improves development efficiency and maintainability.
