2009-02-11Apparently some MachineBasicBlock's don't have corresponding llvm basic blocks.Evan Cheng

2009-01-15Move a few containers out of ScheduleDAGInstrs::BuildSchedGraphDan Gohman
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62275 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-19Experimental post-pass scheduling support. Post-pass schedulingDan Gohman
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
