================
Comment at: lib/Target/PowerPC/PPCISelLowering.cpp:681-683
+      // Legalization will eliminate the illegal type, and finally LXSIWAX can
+      // be generated.
+      setLoadExtAction(ISD::EXTLOAD, MVT::v16i8, MVT::v4i8, Custom);
----------------
Now that we are fixing this for v4i8, is it possible to fix this for some other vector types if a similar fix makes sense for them? For example does it make sense to make a similar change for v4i16 or v2i16 as well?
