lei added inline comments.


================
Comment at: clang/include/clang/Basic/BuiltinsPPC.def:116
 BUILTIN(__builtin_ppc_fres, "ff", "")
+BUILTIN(__builtin_ppc_stbcx, "icD*i", "")
 
----------------
maybe move this up to where `__builtin_ppc_stdcx` is defined.  To match what you did in `PPC.cpp`


================
Comment at: clang/test/CodeGen/builtins-ppc-xlcompat-pwr8.c:31
+  return __builtin_ppc_stbcx(c_addr, c);
+}
----------------
Why not just add this tc to `clang/test/CodeGen/builtins-ppc-xlcompat-LoadReseve-StoreCond.c`?
The other related store functions are tested there.
