================
Comment at: llvm/lib/CodeGen/MachineVerifier.cpp:1704
+        // run on the SSA function just before phi elimination.
+        if (MO->isUndef() && MRI->isSSA())
+          report("Generic virtual register use cannot be undef", MO, MONum);
----------------
The isSSA check here is a leftover and irrelevant for generic vregs
