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)
BR
Alex
