To keep a long story short: no, it does not. I guess you're referring
to the gp register that points to the GOT (Global Offset Table) in ELF.
The primary difference between Mach-O and ELF is that Mach-O code references
data using a direct offset, while ELF indirects all data access through
the global offset table.
