[PATCH] D135968: [FuncSpec][NFC] Refactor finding specialisation opportunities

[Chuanqi Xu via Phabricator via llvm-commits]

ChuanqiXu added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/FunctionSpecialization.cpp:670-672
-    // No point in specialization if the argument is unused.
-    if (A->user_empty())
-      return false;
----------------
Why this check missed?
