V3MergeCond merges consecutive conditional `_ = cond ? _ : _` and `if (cond) ...` statements. This patch adds an analysis and ordering phase that moves statements with identical conditions closer to each other, in order to enable more merging opportunities. This in turn eliminates a lot of repeated conditionals which reduced dynamic branch count and branch misprediction rate. Observed 6.5% improvement on multi-threaded large designs, at the cost of less than 2% increase in Verilation speed. |
