* Matthias Clasen:
not to mention hardware continuously getting faster too...
The proposal is about enabling this feature for older hardware. Recent
x86-64 CPUs can maintain an array of return addresses in hardware (so
basically the backtrace is available directly). Kernel patches to
enable this feature exist, but have not been merged yet. Fedora
userspace has been prepared for this since around Fedora 28 or so, and
we should be able to turn this on with just a glibc update once the
kernel feature lands upstream.
Thanks,
Florian
