| * | Rewrite the SDep class, and simplify some of the related code. | Dan Gohman | 2008-12-09 | 1 | -8/+8 |
| | | | | | | | | | | | | | | | | | | The Cost field is removed. It was only being used in a very limited way, to indicate when the scheduler should attempt to protect a live register, and it isn't really needed to do that. If we ever want the scheduler to start inserting copies in non-prohibitive situations, we'll have to rethink some things anyway. A Latency field is added. Instead of giving each node a single fixed latency, each edge can have its own latency. This will eventually be used to model various micro-architecture properties more accurately. The PointerIntPair class and an internal union are now used, which reduce the overall size. llvm-svn: 60806 | ||||
| * | Experimental post-pass scheduling support. Post-pass scheduling | Dan Gohman | 2008-11-19 | 1 | -0/+72 |
| 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 | |||||
