we want to elide flushes, doing so requires more sophisticated analysis than I'd like in the middle of isel. also, it should be done before forming preambles for efficiency (notice the uniform reduction here). let's do it with a NIR pass. total instructions in shared programs: 2768481 -> 2757832 (-0.38%) instructions in affected programs: 644084 -> 633435 (-1.65%) helped: 2242 HURT: 18 helped stats (abs) min: 1 max: 349 x̄: 4.77 x̃: 3 helped stats (rel) min: 0.01% max: 34.91% x̄: 3.19% x̃: 2.19% HURT stats (abs) min: 1 max: 19 x̄: 2.89 x̃: 1 HURT stats (rel) min: 0.24% max: 7.94% x̄: 1.27% x̃: 0.81% 95% mean confidence interval for instructions value: -5.20 -4.22 95% mean confidence interval for instructions %-change: -3.30% -3.01% Instructions are helped. total alu in shared programs: 2182880 -> 2172352 (-0.48%) alu in affected programs: 513166 -> 502638 (-2.05%) helped: 2235 HURT: 16 helped stats (abs) min: 1 max: 349 x̄: 4.73 x̃: 3 helped stats (rel) min: 0.02% max: 37.65% x̄: 3.70% x̃: 2.59% HURT stats (abs) min: 1 max: 19 x̄: 2.50 x̃: 1 HURT stats (rel) min: 0.33% max: 3.74% x̄: 1.04% x̃: 0.91% 95% mean confidence interval for alu value: -5.16 -4.20 95% mean confidence interval for alu %-change: -3.83% -3.49% Alu are helped. total fscib in shared programs: 2178643 -> 2168059 (-0.49%) fscib in affected programs: 514666 -> 504082 (-2.06%) helped: 2243 HURT: 17 helped stats (abs) min: 1 max: 349 x̄: 4.74 x̃: 3 helped stats (rel) min: 0.02% max: 37.65% x̄: 3.74% x̃: 2.59% HURT stats (abs) min: 1 max: 19 x̄: 2.65 x̃: 1 HURT stats (rel) min: 0.33% max: 14.71% x̄: 1.85% x̃: 0.93% 95% mean confidence interval for fscib value: -5.16 -4.20 95% mean confidence interval for fscib %-change: -3.87% -3.53% Fscib are helped. total bytes in shared programs: 18467348 -> 18403042 (-0.35%) bytes in affected programs: 4403648 -> 4339342 (-1.46%) helped: 2247 HURT: 20 helped stats (abs) min: 2 max: 2132 x̄: 28.73 x̃: 18 helped stats (rel) min: 0.01% max: 33.53% x̄: 2.80% x̃: 1.94% HURT stats (abs) min: 4 max: 72 x̄: 12.60 x̃: 6 HURT stats (rel) min: 0.23% max: 6.58% x̄: 1.06% x̃: 0.75% 95% mean confidence interval for bytes value: -31.29 -25.45 95% mean confidence interval for bytes %-change: -2.90% -2.64% Bytes are helped. total regs in shared programs: 864605 -> 864442 (-0.02%) regs in affected programs: 4692 -> 4529 (-3.47%) helped: 68 HURT: 48 helped stats (abs) min: 1 max: 54 x̄: 7.25 x̃: 3 helped stats (rel) min: 4.26% max: 43.20% x̄: 13.21% x̃: 10.53% HURT stats (abs) min: 1 max: 36 x̄: 6.88 x̃: 6 HURT stats (rel) min: 3.64% max: 91.67% x̄: 23.12% x̃: 24.00% 95% mean confidence interval for regs value: -3.60 0.79 95% mean confidence interval for regs %-change: -2.10% 5.75% Inconclusive result (value mean confidence interval includes 0). total uniforms in shared programs: 2120927 -> 2120911 (<.01%) uniforms in affected programs: 770 -> 754 (-2.08%) helped: 6 HURT: 0 helped stats (abs) min: 2 max: 4 x̄: 2.67 x̃: 2 helped stats (rel) min: 1.79% max: 2.70% x̄: 2.13% x̃: 1.96% 95% mean confidence interval for uniforms value: -3.75 -1.58 95% mean confidence interval for uniforms %-change: -2.50% -1.76% Uniforms are helped. total threads in shared programs: 27612224 -> 27613056 (<.01%) threads in affected programs: 7168 -> 8000 (11.61%) helped: 6 HURT: 3 helped stats (abs) min: 64 max: 192 x̄: 170.67 x̃: 192 helped stats (rel) min: 8.33% max: 23.08% x̄: 20.62% x̃: 23.08% HURT stats (abs) min: 64 max: 64 x̄: 64.00 x̃: 64 HURT stats (rel) min: 8.33% max: 9.09% x̄: 8.59% x̃: 8.33% 95% mean confidence interval for threads value: -3.17 188.06 95% mean confidence interval for threads %-change: -0.92% 22.69% Inconclusive result (value mean confidence interval includes 0).
