Dan Gohman ee2e403545 Add a new "fast" scheduler. This is currently basically just a ... copy of the BURRList scheduler, but with several parts ripped out, such as backtracking, online topological sort maintenance (needed by backtracking), the priority queue, and Sethi-Ullman number computation and maintenance (needed by the priority queue). As a result of all this, it generates somewhat lower quality code, but that's its tradeoff for running about 30% faster than list-burr in -fast mode in many cases. This is somewhat experimental. Moving forward, major pieces of this can be refactored with pieces in common with ScheduleDAGRRList.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56307 91177308-0d34-0410-b5e6-96231b3b80d8		2008-09-18 16:26:26 +00:00
