[PATCH] D82444: [SLP] Make sure instructions are ordered when computing spill cost.

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:3769-3778
+  SmallVector<Instruction *, 16> OrderedScalars;
   for (const auto &TEPtr : VectorizableTree) {
     Instruction *Inst = dyn_cast<Instruction>(TEPtr->Scalars[0]);
     if (!Inst)
       continue;
+    OrderedScalars.push_back(Inst);
+  }
----------------
Can we use a `set` instead of the vector with sort?
