示例1: updateRAWDependencies
void DispatchStage::updateRAWDependencies(ReadState &RS,
const MCSubtargetInfo &STI) {
SmallVector<WriteRef, 4> DependentWrites;
collectWrites(DependentWrites, RS.getRegisterID());
RS.setDependentWrites(DependentWrites.size());
// We know that this read depends on all the writes in DependentWrites.
// For each write, check if we have ReadAdvance information, and use it
// to figure out in how many cycles this read becomes available.
const ReadDescriptor &RD = RS.getDescriptor();
const MCSchedModel &SM = STI.getSchedModel();
const MCSchedClassDesc *SC = SM.getSchedClassDesc(RD.SchedClassID);
for (WriteRef &WR : DependentWrites) {
WriteState &WS = *WR.getWriteState();
unsigned WriteResID = WS.getWriteResourceID();
int ReadAdvance = STI.getReadAdvanceCycles(SC, RD.UseIndex, WriteResID);
WS.addUser(&RS, ReadAdvance);
}
