+    case TargetTransformInfo::RGK_FixedWidthVector:
+      return TypeSize::getFixed((ST->hasNEON() || ST->hasMVEIntegerOps()) ? 128
+                                                                          : 0);
+    case TargetTransformInfo::RGK_ScalableVector:
----------------
Happy as is but do think the following looks nicer:
```
if (ST->hasNEON())
  return TypeSize::getFixed(128);
if (ST->hasMVEIntegerOps())
  return TypeSize::getFixed(128);
return TypeSize::getFixed(0);
```
