There is currently no path to lower scf.forall to scf.parallel with the goal of targeting the OpenMP dialect. In the SCF->ControlFlow conversion, scf.forall is briefly converted to scf.parallel, but the scf.parallel is lowered directly to a sequential loop. This makes experimenting with scf.forall for CPU execution difficult. This change factors out the rewrite in the SCF->ControlFlow pass into a utility function that can then be used in the SCF->ControlFlow lowering and via a separate -scf-forall-to-parallel pass. --------- Co-authored-by: Spenser Bauman <sabauma@fastmail>
