In the list-burr's pseudo two-addr dependency heuristics, don't add dependencies on nodes with exactly one successor which is a COPY_TO_REGCLASS node. In the case that the copy is coalesced away, the dependence should be on the user of the copy, rather than the copy itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69309 91177308-0d34-0410-b5e6-96231b3b80d8
