I'd think we shouldn't do anything even for printing out a warning
unless
doing it is proved to be useful.

Just in case, a little update for this thread:


There was a talk about "Protecting the code: Control Flow Enforcement
Technology" during the recent

llvm-dev meeting (https://llvm.org/devmtg/2018-04/talks.html#Talk_17).


It was mentioned that some support is already implemented in LLVM. I did not
have chance to look close on

it though. Whole feature requires linker side support, current status: bfd
support this, gold - still does not.


I would love to see some comments from O. Simhon? in this thread probably.
