================
Comment at: lib/CodeGen/TargetPassConfig.cpp:628
+             RegAlloc == &createFastRegisterAllocator) &&
+        "Must use fast (default) register allocator for unoptimized regalloc.");
     addFastRegAlloc(createRegAllocPass(false));
----------------
Agreed with Matthias, that should be a fatal error.
