Issue: - Single construct used to throw a semantic error for copyprivate and nowait clause when used in the single directive. - Also, the copyprivate with nowait restriction has been removed from OpenMP 6.0 Fix: - Allow copyprivate and nowait on both single and end single directive - Allow at most one nowait clause - Throw a warning when the same list item is used in the copyprivate clause on the end single directive From Reference guide (OpenMP 5.2, 2.10.2): ``` !$omp single [clause[ [,]clause] ... ] loosely-structured-block !$omp end single [end-clause[ [,]end-clause] ...] clause: copyprivate (list) nowait [...] end-clause: copyprivate (list) nowait ``` Towards: https://github.com/llvm/llvm-project/issues/110008
