PR tree-opt/28937 * tree-flow.h (tree_ssa_unswitch_loops): Return unsigned int. (canonicalize_induction_variables): Likewise. (tree_unroll_loops_completely): Likewise. (tree_ssa_prefetch_arrays): Likewise. (remove_empty_loops): Likewise. * tree-ssa-loop-unswitch.c (tree_ssa_unswitch_loops): Return TODO_cleanup_cfg instead of directly calling cleanup_tree_cfg_loop. * tree-ssa-loop-ivcanon.c (canonicalize_induction_variables): Likewise. (tree_unroll_loops_completely): Likewise. (remove_empty_loops): Likewise. * tree-ssa-loop-prefetch.c (tree_ssa_prefetch_arrays): Likewise. * tree-ssa-loop.c (tree_ssa_loop_unswitch): Use the return value of tree_ssa_unswitch_loops.
