This is a simple, cheap infrastructure for analyzing the shape of a DAG. It recognizes uniform DAGs that take the shape of bottom-up subtrees, such as the included matrix multiplication example. This is useful for heuristics that balance register pressure with ILP. Two canonical expressions of the heuristic are implemented in scheduling modes: -misched-ilpmin and -misched-ilpmax. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168773 91177308-0d34-0410-b5e6-96231b3b80d8 |
