First your figure is grossly incorrect in practice, since most programs are dynamically linked to several shared object libraries (including Then, you can understand the address space of a process of pid 1234 with You cannot really “relocate” (you actually mean “move”) the text section. Some addresses are built inside the code. However, read about the -fPIE option of Of course, you can access the symbols of a program (from inside) if you link it with the -rdynamic flag and if you use dlopen(3) (and See also wikipages about address space, virtual memory, ASLR, position independent code, relocation, ABI, JIT compilation, name mangling and the x86-64 ABI spec and the Advanced Linux Programming book.<\/p>\n","protected":false},"excerpt":{"rendered":" It is operating system specific; I am answering for Linux only.
