# 调用对应的 ld 以及加载同文件夹下的 LLVMgold.dll 来完成链接过程

# 同时处理 --extra-arguments-from-file 和
|

# --output-version-info 参数
|

# --extra-arguments-from-file filepath
|
||
# 接受一个参数、是一个文件路径，里面每一行都是一个需要
|
||
# 传递给 ld 的参数，这样方便把一些 ld 的参数放到文件中
|

# --output-version-info output-file-path

# 接受一个参数，指定 version 信息的输出文件
|

# 当指定这个参数时候、会调用同文件夹下的 pi32-link-version 产生
|

# 版本信息（聚合了所有库的版本信息，即 version.o 的内容 )
