Questions and Answers
What is the difference between a cross-compiler and a bootstrap compiler?
A cross-compiler produces code for a different CPU or operating system than the one on which it runs, while a bootstrap compiler is a temporary compiler used for compiling a more permanent or better optimized compiler for a language.
What is the primary purpose of a compiler?
The primary purpose of a compiler is to translate computer code from one programming language into another language.
What is the function of a decompiler?
A decompiler translates from a low-level language to a higher level one.

Study Notes
Compiler Overview
- The primary purpose of a compiler is to transform high-level programming code into machine code that a computer can execute.
- Compilers are classified based on various factors like the source and target language, and the compilation approach (e.g., just-in-time, ahead-of-time).
Cross-Compiler vs. Bootstrap Compiler
- A cross-compiler generates machine code for a different platform than the one it is running on, enabling the development of software for multiple architectures.
- A bootstrap compiler is a self-hosting compiler used to implement or update a compiler for a new programming language or a new version of the same language.
Functions of Compilers and Related Tools
- The function of a decompiler is to convert machine code back into high-level code, aiding in reverse engineering and understanding of compiled programs.
- A source-to-source compiler, or transpiler, translates code from one high-level language to another, facilitating language interoperability.
- Compilers produce various output forms, including object code, which is an intermediate representation of compiled source code.
Compilation Process
- According to the Analysis – Synthesis Model of compilation, the two main parts are:
- Analysis: This phase checks the source code for syntactic and semantic correctness and generates intermediate representations.
- Synthesis: This phase takes the intermediate representation and produces the final machine code or output.
Functions of Analysis and Synthesis
- The analysis part of compilation focuses on breaking down the source code into manageable parts to identify errors and generate an intermediate representation.
- The synthesis part of compilation focuses on assembling the code into final output, optimizing and translating it into machine-readable format.
Key Roles in Computing
- The primary function of a compiler in computing is to ensure that programs written in high-level languages can be executed by hardware efficiently and accurately.
- Compilers play a crucial role in programming environments, improving code execution and facilitating development across platforms and languages.
