新版本 GCC / LLVM 安装
- 获取并下载 GCC / LLVM 项目源代码：
- 编译安装
- 混合 LLVM / GCC 安装，使其能配合混用；
配置环境
- 启用环境变量;
- 写入库加载路径；
参考脚本
# GCC 编译安装（考虑参考当前系统 GCC 编译选项 gcc -V）
wget https://ftp.gwdg.de/pub/misc/gcc/releases/gcc-13.2.0/gcc-13.2.0.tar.xz
tar xf gcc-13.2.0.tar.xz
cd gcc-13.2.0

# LLVM 编译安装（重合上面 GCC 安装，自动融合使用）
wget https://github.com/llvm/llvm-project/releases/download/llvmorg-17.0.4/llvm-project-17.0.4.src.tar.xz
tar xf llvm-project-17.0.4.src.tar.xz
