References from the data segment use absolute relocations.
References from PIC code use the GOT.
So an indirection through the GOT is added to every access to a
non-static global if you compile with -fPIC?
My understanding was references using the GOT have the same
number of indirections as in the PLT -- that is, a one-time cost
for the dynamic linker to dereference and replace an entry with
the absolute address -- and the major difference is PLT is done
lazily, while GOT is fixed up in its entirety at runtime.
Having said that, now I wonder if I'm misunderstanding the
question?
