[x265] [PATCH 0/6] AArch64: Run-time CPU Feature Detection

[Hari Limaye]

Hi,

This patch series adds run-time CPU feature detection for AArch64 ISA extensions on Linux, Apple Silicon and Windows platforms.

We've benchmarked with vs. without RTFD and observed no performance penalty with RTFD.

The series is based on the Release_4.1 branch.

Many thanks,
Hari
