There's actually several papers covering the evolution of our relocation 
system, and those are probably the best documentation of the approach we 
use.
http://www.paradyn.org/html/publications-by-year.html

I'd highlight Bernat and Miller, 2011, "Anywhere, Any Time Binary 
Instrumentation" as the best overview of our current approach; there's 
been incremental evolution since then but that covers our last radical 
redesign of the relocation system.
If you've got more specific questions after reading that, this list is a 
perfectly fine venue for those, but there's not a ton of documentation 
per se, just institutional knowledge and (sometimes) comments in the code.
