This revision is now accepted and ready to land.

I have one minor nit and that's it. Otherwise LGTM.



================
Comment at: llvm/lib/Target/PowerPC/PPCISelDAGToDAG.cpp:7651
+    const bool OpcodeIsAIXTocData =
+        BaseOpcode == PPC::ADDItoc || BaseOpcode == PPC::ADDItoc8;
+
----------------
nit:
Just add a comment here to say that `PPC::ADDItoc` and `PPC::ADDItoc8` are only used for AIX small code model.
It's not obvious from the name of the pseudo instruction so this tripped me up initially.
