  "message": "Switch the order of calculating 2-D inverse transform\n\nThe 2-D inverse transform X \u003d M1*Z*Transposed_M2 was calculated\nin 2 steps from left to right:\n1. Vertical transform: Y \u003d M1*Z\n2. Horizontal transform: X\u003d Y*Transposed_M2\nIn SIMD, a transpose is needed in vertical transform.\n\nHere, switched the calculation order to do it from right to left.\nIn this way, we could eliminate that transpose by writing the\nintermediate results out to their transposed positions.\n\nChange-Id: I34dfe5eb01292f6e363712420d99475e2e81e12c\n",
