1. -b bounds-checking 内存安全 - 编译 bcheck.o/bt-exe.o/bt-log.o 运行时 - 数组越界/野指针检测，精确定位文件和行号 - 测试: strcpy 溢出和数组越界均被捕获 2. pcc-asm 汇编查看工具 (bin/pcc-asm.exe) - 反汇编 pcc 生成的二进制 (调用 llvm-objdump) - 查看 x86-64 机器码与汇编指令 3. pcc-impdef DLL导入工具 (bin/pcc-impdef.exe) - 解析 PE 导出表生成 .def 文件 - 测试: kernel32.dll 1693 个导出全部正确解析 4. pcc-get 包管理器 (bin/pcc-get.exe) - install/remove/list/root 命令 - 支持本地包目录和 URL 下载安装 - 安装头文件到 include/、库到 lib/ - 测试: mymath 包安装→编译→链接→运行 全流程 5. 交叉编译演示 - 构建 ARM64 交叉编译器 (pcc-arm64.exe) - 构建 RISC-V 交叉编译器 (pcc-riscv64.exe) - 生成 elf64-littleaarch64 / elf64-littleriscv 对象 - 反汇编验证: 真正的 ARM64/RISC-V 机器码
