  "message": "Improve sad3x16 SSE2 function\n\nVp9_sad3x16_sse2() is heavily called in decoder, in which the\nunaligned reads consume lots of cpu cycles. When CONFIG_SUBPELREFMV\nis off, the unaligned offset is 1. In this situation,\nwe can adjust the src_ptr to be 4-byte aligned, and then do the\naligned reads. This reduced the reading time significantly. Tests\non 1080p clip showed over 2% decoder performance gain with\nCONFIG_SUBPELREFM off.\n\nChange-Id: I953afe3ac5406107933ef49d0b695eafba9a6507\n",
