I noticed some things related to this while implementing support for bitfield_select / BFN in BRW. shader-db: Lunar Lake total instructions in shared programs: 17183140 -> 17183128 (<.01%) instructions in affected programs: 3830 -> 3818 (-0.31%) helped: 6 / HURT: 0 total cycles in shared programs: 889936934 -> 889936056 (<.01%) cycles in affected programs: 253758 -> 252880 (-0.35%) helped: 4 / HURT: 2 No shader-db changes on any other Intel platform. fossil-db: Lunar Lake Totals: Instrs: 233285343 -> 233284796 (-0.00%); split: -0.00%, +0.00% Cycle count: 32756777978 -> 32756399804 (-0.00%); split: -0.00%, +0.00% Max live registers: 71738646 -> 71738626 (-0.00%) Non SSA regs after NIR: 67837900 -> 67837902 (+0.00%) Totals from 177 (0.02% of 790723) affected shaders: Instrs: 389849 -> 389302 (-0.14%); split: -0.14%, +0.00% Cycle count: 356341872 -> 355963698 (-0.11%); split: -0.11%, +0.01% Max live registers: 39364 -> 39344 (-0.05%) Non SSA regs after NIR: 70453 -> 70455 (+0.00%) Meteor Lake, DG2, and Ice Lake had similar results.
