Why code generation produces executable output in Compiler Design - Quick Recap

Recall & Review

beginner

What is the main purpose of code generation in a compiler?

The main purpose of code generation is to translate the intermediate representation of a program into executable machine code that a computer can run directly.

How does code generation ensure the output is executable?

Code generation produces output in a format that matches the target machine's instruction set, so the output can be loaded and run by the computer's processor.

intermediate

What role does the target machine architecture play in code generation?

The target machine architecture defines the instructions and formats that code generation must produce to create executable code compatible with that machine.

Why can't code generation produce output in a high-level language?

Because the goal is to create executable output, code generation must produce low-level machine code or assembly, which the computer hardware can directly execute, unlike high-level languages which need further translation.

What is the difference between code generation and interpretation regarding executable output?

Code generation creates a standalone executable file that runs directly on hardware, while interpretation executes code line-by-line without producing a separate executable file.

What does code generation produce in a compiler?

A Syntax trees

B High-level source code

C Comments and documentation

D Executable machine code

Code generation produces executable machine code that the computer can run directly.

Why must code generation match the target machine's instruction set?

A To ensure the output can be executed by the processor

B To make the code easier to read

C To improve compilation speed

D To generate comments

Matching the target machine's instruction set ensures the output is executable by that machine.

Which of these is NOT a reason code generation produces executable output?

A To allow the program to run on hardware

B To create a file the operating system can load

C To generate human-readable code

D To translate intermediate code into machine instructions

Code generation focuses on machine instructions, not human-readable code.

What is the difference between code generation and interpretation?

A Code generation creates executable files; interpretation runs code directly

B Code generation runs code directly; interpretation creates files

C Both produce executable files

D Neither produces executable output

Code generation produces executable files, while interpretation executes code without creating separate executables.

Which part of the compiler produces output that the computer can run?

A Lexical analysis

B Code generation

C Syntax analysis

D Semantic analysis

Code generation produces the final machine code that the computer executes.

Explain why code generation produces executable output and how it relates to the target machine.

Think about how the computer understands instructions.

Describe the difference between code generation and interpretation in terms of executable output.

Consider how programs run after compilation or interpretation.
