[PATCH] D105246: [AbstractAttributor] Fold function calls to `__kmpc_is_spmd_exec_mode` if possible

[Jon Chesterfield via Phabricator via llvm-commits]

JonChesterfield added a comment.

I wonder if this is separable.

Could we have an attribute, 'openmp_called_in_spmd_mode' or similar, which we apply to functions when that is always true, similar to the above logic.

We could then have a pass which, for functions with that attribute set, folds call instructions within that function appropriately.
