  "message": "Fix C vs intrinsic mismatch of aom_hadamard_32x32() function\n\nThis CL resolves the mismatch between C and intrinsic implementation\nof aom_hadamard_32x32 function. The mismatch was due to integer\noverflow during the addition operation in the intrinsic functions.\nSpecifically, the addition in the intrinsic function was performed\nat the 16-bit level, while the calculation of a0 + a1 resulted in\na 17-bit value.\n\nThis code change addresses the problem by performing\nthe addition at the 32-bit level (with sign extension) in both SSE2\nand AVX2, and then converting the results back to the 16-bit level\nafter a right shift.\n\nBug: aomedia:3455\n\nChange-Id: If8504888cd8a905eb4f550c50305459d64c829c2\n(cherry picked from commit 38d838c15bdb64621de89b6dc505607a177eaf86)\n",
