...- XCore As part of this, I'd fix tests that fail due to instruction re-orderings, but, I *wouldn't* try to do performance testing of any sort. The targets from the above list that still use the old code which surprise me are ARM and PPC. However, both also usually seem to return true from enablePostRAScheduler -- maybe they really just want to avoid doing machine scheduling both pre-RA and post-RA, and the fact that it also causes the old selectiondag scheduler to get used is an unintended consequence? (And thus, would actually want enableMachineScheduler() -> false, but with Sched::Source as the se...

Do you have another solution in mind ? I don't really understand this. TargetMachine and TTI may be quite expensive to initialize. Doing so for
