Change the informal convention of DBG_VALUE so that we can express a
register-indirect address with an offset of 0. It used to be that a DBG_VALUE is a register-indirect value if the offset (operand 1) is nonzero. The new convention is that a DBG_VALUE is register-indirect if the first operand is a register and the second operand is an immediate. For plain registers use the combination reg, reg. rdar://problem/13658587 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180816 91177308-0d34-0410-b5e6-96231b3b80d8
