lib file link mechanism [Copy link]

May I ask, what is the link mechanism of lib files like? Is there any information I can check? I did the following test: (1) In a linked file, add uncalled functions and variables. After generating a .a file, the map file will allocate addresses. (2) In a file that is not called by any module, add uncalled functions and variables. After generating a .a file, the map file will not allocate addresses. (3) In a linked file, call the file in (2). After generating a .a file, the map file will allocate addresses.

It will remove useless code and won't give you things you don't need.

Is there any relevant information I can look at for knowledge in this area? Thank you
