WebDynamic executables, however, are generally not created from position-independent code. Any references to external data they make can seemingly only be achieved at runtime by modifying the code that makes the reference. Modifying a read-only text segment is to be avoided. The copy relocation technique can solve this reference. WebIn the most common case, there are three sections: the text section, which holds instructions and read-only data; the data section, which holds initialized writable data; and the bss section, which holds uninitialized data.
