(expand_omp_target) [ENABLE_CHECKING]: Same. (execute_expand_omp): Reinstate LOOPS_HAVE_SIMPLE_LATCHES if in ssa. [ENABLE_CHECKING]: Call verify_loop_structure for cfun if !LOOPS_NEED_FIXUP. (expand_omp_for_static_nochunk): Handle case that omp_for already has its own loop struct. * tree-parloops.c (create_parallel_loop): Add comment about breaking LOOPS_HAVE_SIMPLE_LATCHES. Record new exit. (gen_parallel_loop): Remove call to cancel_loop_tree. (parallelize_loops): Skip loops that are inner loops of parallelized loops. (pass_parallelize_loops::execute): Clear LOOPS_HAVE_SIMPLE_LATCHES on loop state. [ENABLE_CHECKING]: Call verify_loop_structure.
