Compile2024-Simple-sysy-Compiler

Introduction / 简介

This is a project for the 2024 Compiler Theory course design in Jilin University. We developed a compiler capable of generating intermediate and target code, supporting basic syntax including arithmetic operations, nested branches, and loops.

这是我们小组在2024编译原理课程设计上的项目。我们实现了一个编译器，能够进行中间代码和目标代码的生成，支持基础的语法例如四则运算，嵌套的分支和循环等等。

Run / 运行指南

Intermediate code generation / 生成中间代码

Installe Flex and Bison (for Windows OS, utilized installation packages from the setup folder) and configure environment variables / 安装flex和bison（windows操作系统可以用setup文件夹中的安装包，并配置环境变量）
Create a new 'build' directory / 新建build文件夹

Execute the following commands: / 运行如下指令：

flex -l sysy.l
bison -d sysy.y
g++ main.cpp lex.yy.c sysy.tab.c -o sys2koopa.exe -std=c++11
sys2koopa input.sy output.koopa

Target code generation / 生成目标代码

Run the koopa2riscv tool provided in the setup to convert output.koopa to output.riscv by executing the following command: / 运行setup中提供的koopa2riscv，比如要将output.koopa转化为output.riscv，需执行：

./koopa2riscv output.koopa output.riscv

Perform this step in a Linux environment. / 这一步操作需要在Linux环境里进行。
