LGTM as long as the redundant clear is removed.



================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:15098
+  case PPC::BI__builtin_ppc_poppar8: {
+    Value *ArgValue = EmitScalarExpr(E->getArg(0));
+
----------------
Isn't this just `Ops[0]`?


================
Comment at: llvm/lib/Target/PowerPC/PPCInstrInfo.td:5276
+def : Pat<(int_ppc_store2r gprc:$a, ForceXForm:$ptr),
+          (STHBRX (RLWINM gprc:$a, 0, 16, 31), ForceXForm:$ptr)>;
+def : Pat<(int_ppc_store4r gprc:$a, ForceXForm:$ptr),
----------------
The clear is redundant. Why do we need to clear the bits that we won't store to begin with?
