Michael Kruse e200df952b [Polly] Port IslScheduleOptimizer to the NewPM. 2021-02-09 23:56:21 -06:00
Michael Kruse 842314b5f0 [Polly] Update isl to isl-0.23-61-g24e8cd12. 
This fixes llvm.org/PR48554

Some test cases had to be updated because the hash function for
union_maps have been changed which affects the output order.

Michael Kruse c0bc995429 [Polly] Fix prevectorization of fused loops. 
The schedule of a fused loop has one isl_space per statement, such that
a conversion to a isl_map fails. However, the prevectorization is
interested in the schedule space only: Converting to the non-union
representation only after extracting the schedule range fixes the problem.

This fixes llvm.org/PR46578
