Dan Gohman 3f23744df4 Fix some register-alias-related bugs in the post-RA scheduler liveness ... computation code. Also, avoid adding output-depenency edges when both defs are dead, which frequently happens with EFLAGS defs. Compute Depth and Height lazily, and always in terms of edge latency values. For the schedulers that don't care about latency, edge latencies are set to 1. Eliminate Cycle and CycleBound, and LatencyPriorityQueue's Latencies array. These are all subsumed by the Depth and Height fields. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61073 91177308-0d34-0410-b5e6-96231b3b80d8		2008-12-16 03:25:46 +00:00
