  "message": "[AArch64] Unroll ARGB1555ToARGBRow_NEON to use full Neon vectors\n\nProcessing more data per loop iteration means that we can use the full\n128-bit Neon vectors and also allows us to use e.g. UZP1 to perform XTN\n+ XTN2 in a single instruction.\n\nThe early Cortex-X cores are not a fan of ST4 .16b with a\npost-increment, so split out the pointer increment to a separate\ninstruction to avoid this bottleneck.\n\nReductions in runtime observed for ARGB1555ToARGBRow_NEON:\n\n Cortex-A55: -18.1%\nCortex-A510: -11.2%\nCortex-A520: -39.5%\n Cortex-A76: -18.0%\nCortex-A715: -34.8%\nCortex-A720: -34.8%\n  Cortex-X1:  -0.9%\n  Cortex-X2:  -4.6%\n  Cortex-X3:  -3.6%\n  Cortex-X4: -20.8%\n\nBug: libyuv:976\nChange-Id: Iae2ac24ffdbc718cd1e05bb77191f8d1df3fcf6f\nReviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5790975\nReviewed-by: Frank Barchard \u003cfbarchard@chromium.org\u003e\nReviewed-by: Justin Green \u003cgreenjustin@google.com\u003e\n",
