--- Comment #6 from Florian Weimer <fweimer at redhat dot com> ---
The kernel approach has changed:
commit 58122bf1d856a4ea9581d62a07c557d997d46a19
Author: Andy Lutomirski <luto@kernel.org>
Date: Sun Jan 24 14:38:10 2016 -0800
x86/fpu: Default eagerfpu=on on all CPUs
So I don't think glibc has to change, unless benchmarks show that using vector
instructions in string operations negatively impact performance or battery life
etc.
