* Apparently some MachineBasicBlock's don't have corresponding llvm basic blocks.Evan Cheng2009-02-111-3/+7

* Move a few containers out of ScheduleDAGInstrs::BuildSchedGraphDan Gohman2009-01-151-3/+3
| | | | | | | | | | | and into the ScheduleDAGInstrs class, so that they don't get destructed and re-constructed for each block. This fixes a compile-time hot spot in the post-pass scheduler. To help facilitate this, tidy and do some minor reorganization in the scheduler constructor functions. llvm-svn: 62275

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. llvm-svn: 59676
