[PATCH] D75893: [OpenMP] Add !range metadata to loads from omp.(ub/lb)

[Kaushik Kulkarni via Phabricator via llvm-commits]

kaushikcfd added a comment.

- Another attempt at making logic, for finding the right loads/stores, general enough to handle all the cases emitted by Clang.
  - Now looks for loads/stores to omp.(ub.lb) only in the same basic block as '__kmpc_for_static_init_4'.
  - Required slight changes in the OpenMP part of Clang to make sure that it fits this pattern.
- Included a test to check setting the ranges of an OpenMP for-directive that has compile-time constant bounds and is enclosed in an outer loop.
