For each symbol that the nm command lists, the symbol's value in hexadecimal (by default) and the symbol type with a coded character precede the symbol.

It depends on predefined symbol and type definitions and is not easily modified or extended.
它依赖于预定义的符号和类型定义,并且不容易进行修改或扩展。
If you're writing a one line function, whose sole purpose in life is addition, and, clearly, this is about addition, well, then it's, in fact, A reasonable to use a shorter symbol like A, but I do have to specify it's type.
