Hi,

I see that the constructor of ScheduleDAGMI looks like:


public:

   ScheduleDAGMI(MachineSchedContext *C, 
std::unique_ptr<MachineSchedStrategy> S,
                 bool RemoveKillFlags)


These lines then seem wrong, in relation to the third argument:

static ScheduleDAGInstrs *createGenericSchedPostRA(MachineSchedContext *C) {
   return new ScheduleDAGMI(C, make_unique<PostGenericScheduler>(C), 
/*IsPostRA=*/true);

return new ScheduleDAGMI(C, make_unique<SystemZPostRASchedStrategy>(C),
                          /*IsPostRA=*/true);

The third argument tells ScheduleDAGInstrs to remove kill flags during 
buildSchedGraph(), and is not the flag for post/pre-ra.

Ok to change comments per patch?

/Jonas
