Dan Gohman	fc54c55296	Generalize the HazardRecognizer interface so that it can be used ... to support MachineInstr-based scheduling in addition to SDNode-based scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62284 91177308-0d34-0410-b5e6-96231b3b80d8	2009-01-15 22:18:12 +00:00
Dan Gohman	343f0c0467	Experimental post-pass scheduling support. Post-pass scheduling ... is currently off by default, and can be enabled with -disable-post-RA-scheduler=false. This doesn't have a significant impact on most code yet because it doesn't yet do anything to address anti-dependencies and it doesn't attempt to disambiguate memory references. Also, several popular targets don't have pipeline descriptions yet. The majority of the changes here are splitting the SelectionDAG-specific code out of ScheduleDAG, so that ScheduleDAG can be moved to libLLVMCodeGen.a. The interface between ScheduleDAG-using code and the rest of the scheduling code is somewhat rough and will evolve. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59676 91177308-0d34-0410-b5e6-96231b3b80d8	2008-11-19 23:18:57 +00:00
