Subject: Plugin access machine code
Date: Thu, 12 Jan 2023 21:06:23 +0100	[thread overview]
Message-ID: <f084ca639fab3aa41745977e900dfe35@student.tuwien.ac.at> (raw)

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
