[x265] [PATCH 0/3] AArch64 sse_pp Optimisations

[Hari Limaye]

Hi,

This series is based on the previously submitted patch-sets (AArch64 saoCuStats Optimisations, AArch64 SAD/SADxN Optimisations), and depends on CMake refactoring performed in those patch-sets.

Geometric mean of performance speedup on a Neoverse V1 machine (higher is better):

Existing Neon  -> Optimised Neon:       1.60x
Optimised Neon -> Armv8.4 Neon DotProd: 1.73x

Many thanks,

Hari
