Optimizations that we are already calling on the Vulkan driver. As preparation to the Vulkan frontend to use v3d_optimize_nir too. We need to add a new parameter to v3d_optimize_nir in order to know if we can call nir_opt_find_array_copies. As we don't track if we are calling nir_var_lower_copies, we explicitly call it when we create the uncompiled shader create. So instead of tracking, we assume that each driver (v3d/v3dv) would call it when the shader is created. So when v3d_optimize_nir is called as part of the process to compile it at the compiler, we call it with allow_copies as false. We exclude on purpose nir_opt_gcm as it is a case of a optimization that could help performance even if it hurts shader db stats. shaderdb stats: total instructions in shared programs: 11705923 -> 11705034 (<.01%) instructions in affected programs: 88350 -> 87461 (-1.01%) helped: 201 HURT: 80 Instructions are helped. total threads in shared programs: 375552 -> 375558 (<.01%) threads in affected programs: 6 -> 12 (100.00%) helped: 3 HURT: 0 total uniforms in shared programs: 3486108 -> 3485789 (<.01%) uniforms in affected programs: 7473 -> 7154 (-4.27%) helped: 90 HURT: 1 Uniforms are helped. total max-temps in shared programs: 2021860 -> 2021802 (<.01%) max-temps in affected programs: 800 -> 742 (-7.25%) helped: 21 HURT: 3 Max-temps are helped. total sfu-stalls in shared programs: 19299 -> 19296 (-0.02%) sfu-stalls in affected programs: 18 -> 15 (-16.67%) helped: 10 HURT: 7 Inconclusive result (value mean confidence interval includes 0). total inst-and-stalls in shared programs: 11725222 -> 11724330 (<.01%) inst-and-stalls in affected programs: 88402 -> 87510 (-1.01%) helped: 201 HURT: 80 Inst-and-stalls are helped. total nops in shared programs: 269674 -> 269386 (-0.11%) nops in affected programs: 3641 -> 3353 (-7.91%) helped: 103 HURT: 29 Nops are helped.
