[PATCH] D118302: [Spill2Reg] Code generation part 2.

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/Spill2Reg.cpp:248
+    MachineInstr *SpillToVector = TII->spill2RegInsertToVectorReg(
+        VectorReg, OldReg, SpillData.MemBits, StackSpill->getParent(),
+        /*InsertBeforeIt=*/StackSpill->getIterator(), TRI);
----------------
Is this assuming you can only spill one register to one vector register? What if you can place multiple values in different subregisters?
