[PATCH] D63496: [WIP] CodeGen: Prototype class for registers

[Justin Bogner via Phabricator via llvm-commits]

bogner added inline comments.


================
Comment at: include/llvm/CodeGen/Register.h:23-25
+  static bool isPhysicalRegister(unsigned Reg) {
+    return int(Reg) > 0;
+  }
----------------
Any particular reason to have static methods that take an unsigned instead of just implementing these directly using `this`'s `Reg` in `isVirtual` and friends?
