Reference type and flags of symbol

Required Methods

raw desc value

Provided Methods

types of references

To simplify stripping of objects that use are used with the dynamic link editor, the static link editor marks the symbols defined an object that are referenced by a dynamicly bound object (dynamic shared libraries, bundles). With this marking strip knows not to strip these symbols.

The ordinal recorded references the libraries listed in the Mach-O file

symbol is not to be dead stripped

symbol is discarded

symbol is weak referenced

coalesed symbol is a weak definition

reference to a weak symbol

symbol is a Thumb function (ARM)

the function is actually a resolver function and should be called to get the address of the real function to use.

symbol is pinned to the previous content.
