rtlanal.c (tablejump_p): False for returns.
* rtlanal.c (tablejump_p): False for returns. * reorg.c (first_active_target_insn): New static function. (find_end_label): Set JUMP_LABEL for a new returnjump. (optimize_skip, get_jump_flags, rare_destination, mostly_true_jump, get_branch_condition, steal_delay_list_from_target, own_thread_p, fill_simple_delay_slots, follow_jumps, fill_slots_from_thread, fill_eager_delay_slots, relax_delay_slots, make_return_insns, dbr_schedule): Adjust to handle ret_rtx in JUMP_LABELs. * jump.c (delete_related_insns): Likewise. (jump_to_label_p): New function. (redirect_target): New static function. (redirect_exp_1): Use it. Adjust to handle ret_rtx in JUMP_LABELS. (redirect_jump_1): Assert that the new label is nonnull. (redirect_jump): Likewise. (redirect_jump_2): Check for ANY_RETURN_P rather than NULL labels. * ifcvt.c (find_if_case_1): Take care when redirecting jumps to the exit block. (dead_or_predicable): Change NEW_DEST arg to DEST_EDGE. All callers changed. Ensure that the right label is passed to redirect_jump. * function.c (emit_return_into_block, thread_prologue_and_epilogue_insns): Ensure new returnjumps have ret_rtx in their JUMP_LABEL. * print-rtl.c (print_rtx): Handle ret_rtx in a JUMP_LABEL. * emit-rtl.c (skip_consecutive_labels): Allow the caller to pass ret_rtx as label. * cfglayout.c (fixup_reorder_chain): Use force_nonfallthru_and_redirect rather than force_nonfallthru. (duplicate_insn_chain): Copy JUMP_LABELs for returns. * rtl.h (ANY_RETURN_P): New macro. (jump_to_label_p): Declare. * resource.c (find_dead_or_set_registers): Handle ret_rtx in JUMP_LABELs. (mark_target_live_regs): Likewise. * basic-block.h (force_nonfallthru_and_redirect): Declare. * cfgrtl.c (force_nonfallthru_and_redirect): No longer static. * config/alpha/alpha.c (alpha_tablejump_addr_vec, alpha_tablejump_best_label): Remove functions. * config/alpha/alpha-protos.c (alpha_tablejump_addr_vec, alpha_tablejump_best_label): Remove declarations. * config/sh/sh.c (barrier_align, split_branches): Adjust for ret_rtx in JUMP_LABELs. * config/arm/arm.c (is_jump_table): Likewise.
