Can'tfigureoutpasseslackofdocumentation

I am using ReDex for my research project in which I am trying to observe the behavior of different combinations of transformations/optimizations on Android Applications.

Due to lack of documentation I am facing a lot of difficulty in understanding few passes/transformations.

For instance I couldn't understand the behavior of:-

1. ReBindRefsPass:- Can't figure out the behaviour


2. RemoveUnreachablePass:- How is this different from LocalDCEPass?


3. Synthetic Optimization:- Can't figure out behavior

It would be really helpful if someone can provide brief summary of the following transformations.
