Description
Schedule trees are an alternative representation of code in DaCe. It is a tree of nodes that represent the execution order of the SDFG. The tree can be used to perform schedule transformations on the SDFG, i.e., erasing an empty
ifbranch, or merging two consecutivefor-loops.A first version of the schedule tree representation was merged with PR #1145, which adds support for creating schedule trees from SDFGs. This PR builds on #1466 and brings a first version of the transformation from schedule tree to SDFG.
