[Kai Luo via Phabricator via cfe-commits]

lkail added inline comments.


================
Comment at: llvm/include/llvm/IR/IntrinsicsPowerPC.td:1535
-  def int_ppc_ldarx : GCCBuiltin<"__builtin_ppc_ldarx">,
-                      Intrinsic<[llvm_i64_ty], [llvm_ptr_ty], [IntrNoMem]>;
 }
----------------
Just curious, compiler optimizes the instruction out even setting `IntrArgMemOnly` and `IntrReadMem` here?
