  "message": "Refactor pair_set_epi16 for speedup\n\nUse _mm_set1_epi32 instead of _mm_set_epi16, less instructions produced\nby compiler. This patch also removes the duplicate define of the same\nfunction.\n\nSpeed test results:\n1. Unittest for each test cases in SSE2/AV1LbdInvTxfm2d shows 60%~80%\nspeedup (except those case with TX_TYPE include iidentity)\n2. A brief speed test shows that with this CL, for speed1 encoder speeds up\n~3% and decoder speeds up ~1.8%.\n(Baseline is 18976fa5f1ce9777276d969190a1ccb51afbcefe)\n\nChange-Id: I2b0e12973fda05a21d6b6eb0f0efe11df6edfb84\n",
