  "message": "[CFL] Constant Propagate Prediction Height\n\nThese changes apply to both low bit depth (LBD)\nand high bit depth (HBD) predictions.\n\nRemove the duplicate tx_size parameter required\nfor CfL prediction, which was only used to get\nthe height. We now use the height. Move the NULL\nprediction functions into cfl.c to unclutter\ncfl.h.\n\nI wanted to reuse the CFL_TYPE macros used by\nsubsampling, but that did not work out, I left\nthe changes made to those macros in.\n\nSmall speedups for all block sizes, except 32x32.\nFor 32x32, the compiler unrolls all the loops\nwhich appears to be slightly slower than the\nprevious code.\n\nSSSE3/CFLPredictTest\n4x4: C time \u003d 408 us, SIMD time \u003d 126 us (~3.2x)\n8x8: C time \u003d 1367 us, SIMD time \u003d 185 us (~7.4x)\n16x16: C time \u003d 5335 us, SIMD time \u003d 648 us (~8.2x)\n32x32: C time \u003d 25477 us, SIMD time \u003d 2301 us (~11x)\n\nAVX2/CFLPredictTest\n4x4: C time \u003d 408 us, SIMD time \u003d 122 us (~3.3x)\n8x8: C time \u003d 1411 us, SIMD time \u003d 205 us (~6.9x)\n16x16: C time \u003d 5542 us, SIMD time \u003d 598 us (~9.3x)\n32x32: C time \u003d 25927 us, SIMD time \u003d 1803 us (~14x)\n\nSSSE3/CFLPredictHBDTest\n4x4: C time \u003d 561 us, SIMD time \u003d 152 us (~3.7x)\n8x8: C time \u003d 2067 us, SIMD time \u003d 262 us (~7.9x)\n16x16: C time \u003d 10399 us, SIMD time \u003d 863 us (~12x)\n32x32: C time \u003d 41489 us, SIMD time \u003d 3403 us (~12x)\n\nAVX2/CFLPredictHBDTest\n4x4: C time \u003d 576 us, SIMD time \u003d 156 us (~3.7x)\n8x8: C time \u003d 2077 us, SIMD time \u003d 268 us (~7.8x)\n16x16: C time \u003d 10324 us, SIMD time \u003d 584 us (~18x)\n32x32: C time \u003d 41976 us, SIMD time \u003d 2119 us (~20x)\n\nChange-Id: Ib4a38e7d2cd37593d94ea58613d1c32232c24421\n",
