In most Unix-like systems, most of the machine code that makes up the dynamic linker is actually an external executable that the operating system kernel loads and executes first in a process address space newly constructed as a result of calling exec or posix_spawn functions. At link time, the path of the dynamic linker that should be used is ...
Examples of file formats use for both dynamic library and executable files include ELF, Mach-O, and PE. A dynamic library is called by different names in different contexts. In Windows and OS/2 the technology is called dynamic-link library. In Unix-like user space, it's called dynamic shared object (DSO), or usually just shared object (SO).
As the dynamic linker holds modules and resolves dependancies, it populates the IAT slots with actual addresses of the corresponding library functions. Although this adds an extra jump, incurring a performance penalty compared to intermodular calls, it minimizes the number of memory pages that that require copy-on-write changes, thus conserving ...
Dynamic loading is a mechanism by which a computer program can, at run time, load a library (or other binary) into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory.
A linker script may be passed to GNU ld to exercise fine grain control of the linking process. [6] Two versions of ld are provided in binutils: the traditional GNU ld based on bfd, and a streamlined ELF-only version called gold. The LLVM project's linker, lld, is designed to be drop-in compatible, [7] and may be used directly with the GNU ...

The motivation for writing gold was to make a linker that is faster than the GNU linker, [3] especially for large applications coded in C++. Unlike the GNU linker, gold does not use the BFD library to process object files. While this limits the object file formats it can process to ELF only, it is also claimed to result in a cleaner and faster ...
