the operand uses the same register as a tied operand: %r1 = add %r1, %r1 If add were a three-address instruction, kill flags would be required on at least one of the uses.

This change makes the kill flag on the untied use operand optional. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122082 91177308-0d34-0410-b5e6-96231b3b80d8
