This is an undergraduate project of the School of Software of Sichuan University, Class of 2021, entitled Visual Compiler System in the Perspective of First-Year Teaching. This project is the sub and kernel of the undergraduate project, which is a compiler that show the process of compiling step by step.
This project aims to implement a C Minus compiler in C/C++ to show the step-by-step compilation process from source to assembly. By showing the compilation process, it helps the cs beginners to have a basic understanding of the compiler. If all else fails, it can always reduce the confusion of freshmen due to the lack of underlying knowledge. This project can be used as a lab's tool for freshmen to learn about compiler on Introdution to Computer System.
- Lexical Analysis: Using the GNU Flex and the doc given by instructor.
- Syntax Analysis: Using the GNU Bison and the Ast coded by ourselves.
- Semantic analysis: self.
- CodeGenerate: Translate the source into MIPS assembly.
