[PATCH][Binutils] aarch64: Enable Cortex-X3 CPU

[Matthieu Longo]

[-- Attachment #1: Type: text/plain, Size: 264 bytes --]

Hi,

This patch adds support for the Cortex-X3 CPU to binutils.

Gas regression testing for aarch64-none-linux-gnu target and found no 
regressions.

Ok for binutils-master? I don't have commit access so I need someone to 
commit on my behalf.

Regards,

Matthieu.
