Re: 1.25.0: aarch64-unknown-linux-gnu with neon support

Hi Chris,

Thank you very much for your reply.
According to:
https://developer.arm.com/Processors/Cortex-A53

The architecture of Cortex-A53 is ARMv8.
Is has "Neon advanced SIMD"

I wonder how to configure crosstool 1.25.0 to fit exactly this CPU for
linux, 64bits.

Best regards,
Zvika
