当前编译状态：
LLVM框架语言：LLVM 12.0.0
工具库依赖：libBoost、LLVM、glib
界面依赖：gtkmm3
编译环境：cmake 3.13 + Deepin 20.1 Beta
编译时若出错请注意LLVM版本号
SysyPlus编译器偏向于生成网络方面的执行代码，让小白开发者也可以做一个简单、易用、高性能、安全的http服务器。后期根据开发进度开发其他功能。
众所周知：c的http晦涩难学，导包过于繁琐。但性能最好，python的http简单，但是是解释型语言，源码直接暴露，java的http也有学习成本， 且针对简单的http服务使用java这种复杂通用性语言有剩余空间，杀鸡焉用牛刀。
SysyPlus编译器致力于打造一个简单语法的http服务器，上手即用语法简单，不用导任何包，不用管依赖问题， 生成的产物为编译好的可执行文件，文件小，安全，且能利用python不能使用的多核cpu线程优势。
以用程序自带访问一次HTTP为例
- IDE GUI可直接进行代码静态分析（变量不存在，函数重复定义等）
- IDE GUI拥有丰富的代码提示功能
- 编译或执行SysyPlus代码
- 当然你也可以当一个文本编辑器
- CGUI
- 开启图形界面编译，生成带GUI的编译器
- DEBUG_FLAG
- 开启词法、语法的调试模式
- 函数定义
- 参数
- 二元表达式
- &&、||
- +、-、*、/、%、!=
- 函数调用
- 传参
- 基础类型、数组、多维数组、函数指针(fun_c<ret,...>)传参
- 传参
- 条件分支关键字
- if
- 循环关键字(c++ -> sysyplus)
- for -> lp
- While -> whl
- break -> out
- continue -> cont
- 函数返回 return -> ret
- 保持单入单出特性
- 全局、局部变量
- 数组
- 全局、局部数组/多维数组
- 数组定义时初始化
- 字符串
- 局部、全局声明、传值
- 语言特色
- sleep(s) 休眠
- echo(str) 输出
- now(null) 获取当前秒数
- web功能
- 创建socket
- 连接url
- 发送GET请求
- 发送POST请求（正在开发中）
- 支持TLSv1.3加密HTTPS（需要openssl支持，现默认使用TLSv1.2，兼容性好）
- 代码插桩/优化功能
- 函数执行时间分析
- 递归函数转非递归（正在开发中）
- 生成AST语法树
- 生成对应系统架构的目标代码
- ...(比较懒，不想写)
- 无需导包
