There is no upper cap set on current Schedule Optimizer to compute schedule. In some cases a very long compile time taken to compute the schedule resulting in hang kind of behavior. This patch introduces a flag 'polly-schedule-computeout' to pass the capwhich is initialized to 300000. This patch handles the compute out cases by bailing out and exiting gracefully. Fixed the test that failed in previous commit. Fixes #69090 |

Polly - Polyhedral optimizations for LLVM ----------------------------------------- http://polly.llvm.org/ Polly uses a mathematical representation, the polyhedral model, to represent and transform loops and other control flow structures. Using an abstract representation it is possible to reason about transformations in a more general way and to use highly optimized linear programming libraries to figure out the optimal loop structure. These transformations can be used to do constant propagation through arrays, remove dead loop iterations, optimize loops for cache locality, optimize arrays, apply advanced automatic parallelization, drive vectorization, or they can be used to do software pipelining.
