Add SVE2 and SME implementations of I444ToRGB24Row Move the READYUV444_SVE_2X and I444TORGB_SVE_2X macros to row_sve.h so they are usable in both SVE2 and SME implementations, and use them to add new I444ToRGB24Row implementations for SVE2 and SME. We need to use the unrolled versions here to use the ST3B interleaving store instructions, since there is no partial vector version of this store instruction. Reduction in time taken observed for the new SVE2 implementation, compared to the existing Neon implementation: Cortex-A510: -57.6% Cortex-A520: -38.1% Cortex-A710: -15.5% Cortex-A715: -9.2% Cortex-A720: -9.2% Cortex-X2: -25.8% Cortex-X3: -26.2% Cortex-X4: -23.2% Cortex-X925: -17.8% Change-Id: I6acd0b798a35e5352d4fad664769f12d3d938ed7 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/6530646 Reviewed-by: Justin Green <greenjustin@google.com> Reviewed-by: Frank Barchard <fbarchard@chromium.org>
