re PR gcov-profile/34610 (ICE with "-fprofile-arcs -fopenmp")
PR gcov-profile/34610 * tree-cfg.c (make_edges): Mark both outgoing edges from OMP_CONTINUE and from OMP_FOR as EDGE_ABNORMAL. * omp-low.c (expand_omp_for): Clear EDGE_ABNORMAL bits from OMP_FOR and OMP_CONTINUE outgoing edges. * tree-profile.c (tree_profiling): Return early if cfun->after_tree_profile != 0. Set cfun->after_tree_profile at the end. * omp-low.c (expand_omp_parallel): Copy after_tree_profile from cfun to child_cfun. * function.h (struct function): Add after_tree_profile bit. * gcc.dg/gomp/pr34610.c: New test.
