Physical registers, in LLVM, are grouped in Register Classes. Elements in the same register class are functionally equivalent, and can be diff --git a/include/llvm/MC/MCRegisterInfo.h b/include/llvm/MC/MCRegisterInfo.h index 956f5e6aa95..c541f055485 100644 --- a/include/llvm/MC/MCRegisterInfo.h +++ b/include/llvm/MC/MCRegisterInfo.h @@ -324,33 +324,6 @@ public: return operator[](RegNo); } - /// getAliasSet - Return the set of registers aliased by the specified - /// register, or a null list of there are none.
