Handle all live physreg defs in the same place. SelectionDAG has 4 different ways of passing physreg defs to users. Collect all of the uses at the same time, and pass all of them to MI->setPhysRegsDeadExcept() to mark the remaining defs dead. The setPhysRegsDeadExcept() function will soon add the required implicit-defs to instructions with register mask operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149708 91177308-0d34-0410-b5e6-96231b3b80d8
