ldvary instructions have implicit writes to rf0 (r5 in Pi4) that are read in follow-up instructions to complete the interpolation calculations so we rather not allocate ldunif(a)'s dst to rf0/r5 during these sequence too to facilitate pairing. This gives us -0.25% of instructions for fragment shaders in shader-db for Pi5 and -0.64% on Pi4. Shader-db Pi5: total instructions in shared programs: 10890641 -> 10889197 (-0.01%) instructions in affected programs: 575506 -> 574062 (-0.25%) helped: 2506 HURT: 1378 Instructions are helped. total max-temps in shared programs: 2226555 -> 2226471 (<.01%) max-temps in affected programs: 5061 -> 4977 (-1.66%) helped: 139 HURT: 78 Max-temps are helped. total sfu-stalls in shared programs: 15143 -> 15166 (0.15%) sfu-stalls in affected programs: 310 -> 333 (7.42%) helped: 134 HURT: 195 Inconclusive result (value mean confidence interval includes 0). total inst-and-stalls in shared programs: 10905784 -> 10904363 (-0.01%) inst-and-stalls in affected programs: 577053 -> 575632 (-0.25%) helped: 2497 HURT: 1415 Inst-and-stalls are helped. total nops in shared programs: 183945 -> 183672 (-0.15%) nops in affected programs: 3862 -> 3589 (-7.07%) helped: 478 HURT: 234 Nops are helped. Shader-db Pi4: total instructions in shared programs: 12842116 -> 12835720 (-0.05%) instructions in affected programs: 996970 -> 990574 (-0.64%) helped: 6027 HURT: 367 Instructions are helped. total max-temps in shared programs: 2251877 -> 2251707 (<.01%) max-temps in affected programs: 2670 -> 2500 (-6.37%) helped: 167 HURT: 9 Max-temps are helped. total sfu-stalls in shared programs: 21132 -> 21093 (-0.18%) sfu-stalls in affected programs: 114 -> 75 (-34.21%) helped: 92 HURT: 55 Sfu-stalls are helped. total inst-and-stalls in shared programs: 12863248 -> 12856813 (-0.05%) inst-and-stalls in affected programs: 1008237 -> 1001802 (-0.64%) helped: 6070 HURT: 359 Inst-and-stalls are helped. total nops in shared programs: 281645 -> 281200 (-0.16%) nops in affected programs: 2241 -> 1796 (-19.86%) helped: 501 HURT: 88 Nops are helped.
