Evan Cheng f4b4c416d3 Eliminate reachability matrix. It has to be calculated before any instruction ... selection is done. That's rather expensive especially in situations where it isn't really needed. Move back to a searching the predecessors, but make use of topological order to trim the search space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29559 91177308-0d34-0410-b5e6-96231b3b80d8		2006-08-08 00:31:00 +00:00
