Common Mistakes

Confusing front-end with back-end

Thinking optimizer is the first step

The front-end of a compiler reads and checks the source code for errors and creates an intermediate representation.

Common Mistakes

Mixing up front-end and back-end roles

Confusing lexer or parser with code generation

The back-end takes the intermediate code and converts it into machine code suitable for the target hardware.

Assuming front-end does optimization

Confusing analysis phases with optimization

Optimization is usually done in the back-end to improve the performance of the machine code.

Common Mistakes

Swapping front-end and back-end

Confusing lexer or linker with these roles

The front-end checks the code structure and meaning, and the back-end produces efficient machine code.

Common Mistakes

Confusing optimizer with front-end

Mixing back-end and linker roles

The front-end creates the intermediate code, the optimizer refines it, and the back-end generates machine code.
