模块间的数据访问目的地址要等到装载时才能确定,ELF文件的做法是在数据段里面建一个指向这些模块间全局变量的指针数组,也被称为全局偏移表(Global Offset Table, GOT),当代码需要引用模块间全局变量时,可以通过GOT中的表项间接的引用。由于GOT是存放在数据段中,所以动态库在装载时可以被修改,每个进程都有独立的副本...

Position-Independent Code The code within a dynamic executable is typically position-dependent, and is tied to a fixed address in memory. Shared objects, on the other hand, can be loaded at different addresses in different processes. Position-independentcode is not tied to a specific address. ...

Position-independent code (PIC) is code that can execute regardless of its absolute address (i.e. by using relative addressing). PIC is used forshared libraries, allowing library code to be located anywhere in memory. To access this content, you must purchase a Membership -check out the diff...
Hello, We have an STM32F37xx MCU (and the ST eval board) and we would like to create Position Independent code (the -fpic switch). Keil has a nice checkbox with "Read-Only Position Independent" etc. Problem is that the standard STM32F3xx setup sets "--apcs=interwork", which will ...
