The new instruction scheduling models provide information about the number of cycles consumed on each processor resource. This makes it possible to estimate ILP more accurately than simply counting instructions / issue width. The functions getResourceDepth() and getResourceLength() now identify the limiting processor resource, and return a cycle count based on that. This gives more precise resource information, particularly in traces that use one resource a lot more than others. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178553 91177308-0d34-0410-b5e6-96231b3b80d8
