[PATCH] D66005: [ARM] Add MVE beats vector cost model

[Sam Parker via Phabricator via llvm-commits]

samparker added inline comments.


================
Comment at: llvm/lib/Target/ARM/ARMTargetTransformInfo.cpp:396
+    // We say MVE moves costs at least the MVEVectorCostFactor, even though
+    // they are scalar instructions. This helps prevent mixing scalar and
+    // vector.
----------------
What part of the architecture suggests that we should avoid mixing scalar and vector?
