During a build of glibc 2.20 with either GCC 4.9.2 and GCC 4.8.4 on Centos 6.4 I get the following error and compilation fails ../sysdeps/x86_64/multiarch/memset-avx2.S:132: Error: no such instruction: `vinserti128 $1,%xmm0,%ymm0,%ymm0' Cheers, Toby

This was fixed for glibc 2.21 by requiring binutils 2.22 or later to build glibc. commit bd80507166253107ce84245c8c93d95368abc982 Author: Andrew Senkevich <andrew.n.senkevich@gmail.com> Date: Mon Nov 10 11:16:46 2014 -0800 Update minimal required bunutils version to 2.22
