mischeduler (pre-RA) experiments
...e 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/SPEC-2006. This gave
no...

top-down vs. bottom-up list scheduling
Hello List!
I am looking at top-down vs. bottom-up list scheduling for simple(r) in-order
cores. First, for some context, below is a fairly representative pseudo-code
example of the sort of DSP-like codes I am looking at:
uint64_t foo(int *pA, int *pB, unsigned N, unsigned C) {
uint64_t sum = 0;
while (N-- > 0) {
A1 = *pA++;
A2 = *pA++;
B1 = *pB++;
B2 =
