Plugin access machine code

[Alex Wieser via Gcc-help <gcc-help@xxxxxxxxxxx>]

Hello,

I am trying to implement a Control Flow Integrity scheme for a custom 
RISCV processor and want to use a gcc plugin to get all of the control 
flow info that I need.
Right now I have a plugin as a pass after the eh_ranges pass, that is 
able to draw a control flow graph and emit new instructions.

1) Is it possible to access the final addresses for any instruction from 
within the gcc plugin?
2) Is there a way to get the actual machine code instructions in the 
plugin while still having access to the control flow information? (So 
still access to the basic blocks and their preds/succs)
