------- Comment #9 from amacleod at redhat dot com 2008-01-08 13:27 ------- yes, many PHIs are eliminated by coalescing. If you wanted to experiment at some point for more accuracy, you can look at the PHI arguments. Any argument which has a different base name than the LHS of the PHI, or is a constant, *will* be a copy if the PHI remains.
