[Quentin Colombet via Phabricator via llvm-commits]

qcolombet added inline comments.


================
Comment at: lib/CodeGen/VirtRegMap.cpp:274
+    // Write out new DBG_VALUE instructions.
+    DebugVars->emitDebugValues(VRM);
+
----------------
DebugVars may be nullptr IIRC what getAnalysisIfAvailable API does.

Make sure to test for it.
