[PATCH] D90040: [AsmPrinter] Use getMnemonic for instruction-mix remark.

[Jessica Paquette via Phabricator via llvm-commits]

paquette added inline comments.


================
Comment at: llvm/include/llvm/MC/MCStreamer.h:457
+  /// access to a instruction printer.
+  virtual StringRef getMnemonic(MCInst &MI) { return ""; }
+
----------------
Would it make sense to make this return an `Optional` to make it clear that this may not necessarily return a mnemonic?
