I believe this was stuck here early because otherwise nir_opt_copy_prop_vars could undo what lower_io_to_temporaries does. However that has since been fixed. Also, we now use scratch for large variables so the comment is stale. On radeonsi these are the shader-db results: Totals: SGPRS: 3955968 -> 3955968 (0.00 %) VGPRS: 2220208 -> 2220220 (0.00 %) Spilled SGPRs: 11387 -> 11387 (0.00 %) Spilled VGPRs: 97 -> 97 (0.00 %) Private memory VGPRs: 2528 -> 2528 (0.00 %) Scratch size: 2656 -> 2656 (0.00 %) dwords per thread Code Size: 76002108 -> 76002204 (0.00 %) bytes LDS: 740 -> 740 (0.00 %) blocks Max Waves: 772779 -> 772776 (-0.00 %) Wait states: 0 -> 0 (0.00 %) Totals from affected shaders: SGPRS: 176 -> 176 (0.00 %) VGPRS: 144 -> 156 (8.33 %) Spilled SGPRs: 0 -> 0 (0.00 %) Spilled VGPRs: 0 -> 0 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 0 -> 0 (0.00 %) dwords per thread Code Size: 12104 -> 12200 (0.79 %) bytes LDS: 0 -> 0 (0.00 %) blocks Max Waves: 28 -> 25 (-10.71 %) Wait states: 0 -> 0 (0.00 %) The few small regressions are due to nir_opt_large_constants kicking in when indirect lowering happens to result in smaller code after optimization since the array is very simple.
