[PATCH] D48663: [Power9] Code Cleanup - Remove needsAggressiveScheduling()

[Eric Christopher via Phabricator via llvm-commits]

echristo added a comment.

Looking pretty good at this point. I am still curious why we've got the scheduling change here...



================
Comment at: lib/Target/PowerPC/PPCSubtarget.cpp:189-190
                                        unsigned NumRegionInstrs) const {
-  if (needsAggressiveScheduling(DarwinDirective)) {
-    Policy.OnlyTopDown = false;
-    Policy.OnlyBottomUp = false;
-  }
+  Policy.OnlyTopDown = false;
+  Policy.OnlyBottomUp = false;

I do wonder "why" we want to do this rather than just that we're doing it.
