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 |
