...(on average 1% improvement,
some improvements of several percent and very little regressions).
Basically, I add a "latency heuristic boost" just above processor
resources checking:
tryCandidate() {
...
// Avoid increasing the max pressure of the entire region.
if (DAG->isTrackingPressure() && tryPressure(TryCand.RPDelta.CurrentMax,
Cand.RPDelta.CurrentMax, TryCand, Cand, RegMax, TRI, DAG->MF))
return;
/// INSERTION POINT
...
}
I had started to experiment with adding tryLatency() in various places,
and found this to be the best spot for SystemZ/...
