================
Comment at: lib/Target/Nios2/MCTargetDesc/Nios2MCTargetDesc.cpp:49
   if (CPU.empty() || CPU == "generic") {
-    if (TT.getArch() == Triple::nios2) {
-      if (CPU.empty() || CPU == "nios2r2") {
-        ArchFS = "+nios2r2";
-      } else {
-        if (CPU == "nios2r1") {
-          ArchFS = "+nios2r1";
-        }
-      }
-    }
+    CPU == "nios2r1";

Current patch does not provide enough functionality to check that CPU=empty is incorrect.
