Yeah, that's a good idea. Ubuntu has a list of packages that were
specifically called out to build with PIE (and as a result are well-tested
One task I haven't had time to do, related to interpreters, is to benchmark
the python testsuite with PIE. A number of years ago, a 15% performance hit
on i386 (due to so few general registers). I'd really like to see the
numbers across all architectures. A future release goal, I think, would be
to build all of amd64 (and any other archs that don't see a big hit) with
PIE by default. Can someone step up to do this?
