Hey @elhewaty !

I left a few comments some time ago, but forgot to hit finalize on the review, sorry!

After some more looking into this, I believe there is additional problems we need to tackle. The biggest is, we have no information about PLT entries. I can see you listed some, but I don't have a solution that covers any possible libraries that can be linked dynamically to the binary BOLT is ran on.
