tqchen opened a new pull request #6667: URL: https://github.com/apache/incubator-tvm/pull/6667
The loop transformations (split, fuse) create bijective maps from a collection of source iterators to target iterators. DetectIterMap is a function that detects such bijective mappings from the lowered index expression. We choose the term quasi affine to be consistent with the terminology used by in polyhedral compilation. DetectIterMap can handle symbolic integers(in split/fuse) to some extent. The utility can be useful in detecting loop transformation patterns and data layout change patterns in TIR. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
