[LLVMdev] Scheduling with RAW hazards
...switching over and start filing bugs. PPC is an example of using MI scheduler out-of-box. Hexagon is an example of customizing it at a high level. You could start off like PPC with minimal customization, but eventually you may want something in between--provide a custom MachineSchedStrategy:
class MyScheduler : public MachineSchedStrategy {...}
namespace llvm {
ScheduleDAGInstrs *createMySched(MachineSchedContext *C) {
ScheduleDAGMI *DAG = new ScheduleDAGMI(C, new MyScheduler());
DAG->addMutation(new MyDAGMutation());
return DAG;
}
} // namespace llvm
static MachineSchedRegistry

[LLVMdev] Scheduling with RAW hazards
I have an instruction that takes no operands, and produces two results,
in two consecutive cycles.
I tried both of the following to my Schedule.td file:
InstrItinData<IIMyInstr, [InstrStage<2, [FuncU]>], [1, 2]>,
InstrItinData<IIMyInstr, [InstrStage<1, [FuncU]>, InstrStage<1,
[FuncU]>], [1, 2]>,
From what I can see in examples, these say that the first
