Detailed Description

ChainedFixupTarget holds all the information about an external symbol necessary to bind this binary to that symbol.

These values are referenced indirectly by chained fixup binds. This structure captures values from all import and symbol formats.

Be aware there are two notions of weak here: WeakImport == true The associated bind may be set to 0 if this symbol is missing from its parent library. This is called a "weak import." LibOrdinal == BIND_SPECIAL_DYLIB_WEAK_LOOKUP This symbol may be coalesced with other libraries vending the same symbol. E.g., C++'s "operator new". This is called a "weak bind."
