  "message": "Refactor and optimize warehouse_efficients_txb()\n\nThis patch improves and simplifies code structure in\nwarehouse_efficients_txb() and related functions by-\n  - Calling the function warehouse_efficients_txb() using switch\n    statement to enforce loop-invariant code for TX_CLASS.\n  - Avoiding redundant abs() computations for zero coefficients in\n    warehouse_efficients_txb() and av1_get_txb_entropy_context().\n  - Optimizing get_tx_type_cost() by computing the transform set type\n    once and reusing it, eliminating repeated calls to\n    av1_get_ext_tx_set_type().\n\nThis change is bit-exact for all presets.\n\nEncoder performance results averaged over all resolutions:\n\n       Encoder Instruction\n  CPU   Count Reduction (%)\n   1        0.48\n   2        0.54\n   3        0.50\n   4        0.30\n   5        0.31\n   6        0.31\n\nChange-Id: I79afe142ee337eb9fa94a1a8d2ceb46b9aba30f2\n",
