So this proposal is for _all_ architectures, including the register-starved 32-bit i?86
where the overhead is, IIRC, around 10%. I am by now quite convinced that x86_64 should
be using PIE by default. As for 32-bit, I’m torn between “this is too much overhead” and
“32-bit isn’t worth the worry, let’s instead make the defaults consistent.”
probably not worth the worry, new machines are x86_64 mostly, keep in
mind RHEL7 dropped i686 at all
even if they are still used - 10% sounds much *but* such old machines
mostly have a special task and are far away from noticeable load and it
really depends on the workload if you even notice 20% performance drop
at least i doubt there is a noticeable userbase with i686 running Fedora
at all *and* would notice the drop noticeable
