Immediate binding:
The runtime linker performs both data reference and function reference relocations during process initialization, before transferring control to the application. This behavior is equivalent to the LD_BIND_NOW behavior in the Solaris operating environment (lazy binding is not supported).
No version checking:
The runtime linker performs no version dependency checking. When looking for a library, the runtime linker looks for a file name matching the library name exactly. This behavior is equivalent to the LD_NOVERSION behavior in the Solaris operating environment.
Weak symbols and aliases:
During symbol resolution, weak symbols will be silently overridden by any global definition with the same name. Weak symbols can be defined alone or as aliases to global symbols. Weak symbols are defined with pragma definitions.
