[PATCH] D75421: [AArch64][GlobalISel] Avoid copies to target register bank for subregister copies

[Jessica Paquette via Phabricator via llvm-commits]

paquette added inline comments.


================
Comment at: llvm/lib/Target/AArch64/AArch64InstructionSelector.cpp:459
+  default:
+    assert(false && "Tried to get minimum size for unknown register bank.");
+  }
----------------
This should be an `llvm_unreachable`, I think. We never want to return anything here.
