[PATCH] D121571: [TableGen] X86 mnemonic tables backend

[Kan Shengchen via Phabricator via llvm-commits]

skan added inline comments.


================
Comment at: llvm/utils/TableGen/X86MnemonicTables.cpp:69
+    // \t
+    StringRef Mnemonic =
+        StringRef(AsmString).take_until([](char C) { return C == '\t'; });
----------------
I'm afraid using `StringRef` here is not safe, `AsmString` is destoryed after each iteration.
