[PATCH] D53931: TableGen: Fix ASAN error

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added inline comments.


================
Comment at: utils/TableGen/SearchableTableEmitter.cpp:168
-                        "' too large to search");
-      return "uint" + utostr(NumBits) + "_t";
     } else if (Field.Enum || Field.IsIntrinsic || Field.IsInstruction)
----------------
How does the problem actually occur?  utostr returns a temporary std::string which should exist until the sum is constructed.  What object is used-after-scope?
