We always supported a mixture of the old itinerary model and new per-operand model, but it required a level of indirection to map itinerary classes to SchedRW lists. This was done for ARM A9. Now we want to define x86 SchedRW lists, with the goal of removing its itinerary classes, but still support the itineraries in the mean time. When I original developed the model, Atom did not have itineraries, so there was no reason to expect this requirement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177226 91177308-0d34-0410-b5e6-96231b3b80d8
