[PATCH] D150398: [VPlan] Model branch cond to enter scalar epilogue in VPlan.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/test/Transforms/LoopVectorize/AArch64/fixed-order-recurrence.ll:54
 ; CHECK:       scalar.ph:
-; CHECK-NEXT:    [[SCALAR_RECUR_INIT:%.*]] = phi i8 [ [[DOTPRE]], [[FOR_BODY_PREHEADER]] ], [ [[VECTOR_RECUR_EXTRACT]], [[MIDDLE_BLOCK]] ]
+; CHECK-NEXT:    [[SCALAR_RECUR_INIT:%.*]] = phi i8 [ [[VECTOR_RECUR_EXTRACT]], [[MIDDLE_BLOCK]] ], [ [[DOTPRE]], [[FOR_BODY_PREHEADER]] ]
 ; CHECK-NEXT:    [[BC_RESUME_VAL:%.*]] = phi i64 [ [[IND_END]], [[MIDDLE_BLOCK]] ], [ 1, [[FOR_BODY_PREHEADER]] ]
----------------
Note that the final branch is now created later than before, which means the block use list order is slightly different, resulting in different order in the incoming block here (and in many other tests)
