LGTM.



================
Comment at: llvm/lib/Target/PowerPC/PPCISelLowering.cpp:15651
              Subtarget.hasVSX()) {
-    return std::make_pair(0U, &PPC::VSRCRegClass);
+    if (VT.isVector())
+      return std::make_pair(0U, &PPC::VSRCRegClass);
----------------
A comment above this line would be useful:
```
// A VSX register for either a scalar (FP) or vector. There is no
// support for single precision scalars on subtargets prior to Power8.
```
