[PATCH][BINUTILS] aarch64: Enable Cortex-X4 CPU

[Saurabh Jha]

[-- Attachment #1.1: Type: text/plain, Size: 642 bytes --]

Hey,


This patch adds support for the Cortex-X4 CPU to binutils.


Regression testing for aarch64-none-elf target and found no regressions.


Okay for binutils-master? I don't have commit access so if it looks 
okay, could someone please help me commit this?


Thanks, Saurabh


bfd/ChangeLog * cpu-aarch64.c (processors): Add cortex-x4 core in
