This workaround is wrong in the sense of failing to correct some broken code sequences and needlessly rejecting some working code sequences. total tuples in shared programs: 123770 -> 123630 (-0.11%) tuples in affected programs: 9548 -> 9408 (-1.47%) helped: 133 HURT: 0 helped stats (abs) min: 1.0 max: 2.0 x̄: 1.05 x̃: 1 helped stats (rel) min: 0.42% max: 16.67% x̄: 4.07% x̃: 1.15% 95% mean confidence interval for tuples value: -1.09 -1.01 95% mean confidence interval for tuples %-change: -4.98% -3.17% Tuples are helped. total cycles in shared programs: 12114.83 -> 12114.50 (<.01%) cycles in affected programs: 34.08 -> 33.75 (-0.98%) helped: 9 HURT: 1 helped stats (abs) min: 0.04166599999999998 max: 0.04166700000000034 x̄: 0.04 x̃: 0 helped stats (rel) min: 0.72% max: 12.50% x̄: 2.99% x̃: 2.04% HURT stats (abs) min: 0.04166700000000034 max: 0.04166700000000034 x̄: 0.04 x̃: 0 HURT stats (rel) min: 0.62% max: 0.62% x̄: 0.62% x̃: 0.62% 95% mean confidence interval for cycles value: -0.05 -0.01 95% mean confidence interval for cycles %-change: -5.27% <.01% Inconclusive result (%-change mean confidence interval includes 0). total arith in shared programs: 4603.42 -> 4601.54 (-0.04%) arith in affected programs: 50.50 -> 48.62 (-3.71%) helped: 41 HURT: 1 helped stats (abs) min: 0.04166599999999998 max: 0.08333299999999999 x̄: 0.05 x̃: 0 helped stats (rel) min: 0.72% max: 33.33% x̄: 17.23% x̃: 13.33% HURT stats (abs) min: 0.04166700000000034 max: 0.04166700000000034 x̄: 0.04 x̃: 0 HURT stats (rel) min: 0.62% max: 0.62% x̄: 0.62% x̃: 0.62% 95% mean confidence interval for arith value: -0.05 -0.04 95% mean confidence interval for arith %-change: -20.93% -12.69% Arith are helped. total quadwords in shared programs: 110116 -> 110009 (-0.10%) quadwords in affected programs: 7829 -> 7722 (-1.37%) helped: 106 HURT: 0 helped stats (abs) min: 1.0 max: 2.0 x̄: 1.01 x̃: 1 helped stats (rel) min: 0.49% max: 7.14% x̄: 1.91% x̃: 1.35% 95% mean confidence interval for quadwords value: -1.03 -0.99 95% mean confidence interval for quadwords %-change: -2.23% -1.59% Quadwords are helped.
