(update_single_exits_after_duplication, update_single_exit_for_duplicated_loop, update_single_exit_for_duplicated_loops): Removed. (duplicate_loop_to_header_edge): Do not call update_single_exits_after_duplication and update_single_exit_for_duplicated_loops. (loop_version): Do not update single_exit information. (fix_loop_structure): Use record_loop_exits instead of mark_single_exit_loops. * tree-ssa-loop-manip.c (tree_transform_and_unroll_loop): Update the lists of loop exits. * cfghooks.c (redirect_edge_and_branch, redirect_edge_and_branch_force, split_edge, merge_blocks): Update the lists of loop exits. * modulo-sched.c (sms_schedule): Pass LOOPS_HAVE_RECORDED_EXITS to loop_optimizer_init. * loop-init.c (loop_optimizer_init): Call record_loop_exits instead of mark_single_exit_loops. (loop_optimizer_finalize): Call release_recorded_exits. * tree-ssa-loop.c (tree_loop_optimizer_init): Pass LOOPS_HAVE_RECORDED_EXITS to loop_optimizer_init. * tree-vectorizer.c (slpeel_tree_duplicate_loop_to_edge_cfg): Do not update single exit information. * lambda-code.c (perfect_nestify): Ditto. * cfgloop.c (flow_loop_free): Destroy the list of exits of the loop. (mark_single_exit_loops): Removed. (alloc_loop, loop_exit_hash, loop_exit_eq, loop_exit_free, get_exit_descriptions, rescan_loop_exit, record_loop_exits, dump_recorded_exit, dump_recorded_exits, release_recorded_exits): New functions. (get_loop_exit_edges, single_exit): Use recorded exit lists. (add_bb_to_loop, remove_bb_from_loops): Update the lists of loop exits. (verify_loop_structure): Verify consistency of the exit lists. (flow_loops_find): Use alloc_loop. Initialize exits hash. (set_single_exit): Removed. * cfgloop.h (struct loop_exit): New function. (struct loop): single_exit_ field replaced by exits field. (LOOPS_HAVE_MARKED_SINGLE_EXITS): Replaced by LOOPS_HAVE_RECORDED_EXITS. (struct loops): Added exits hash. (mark_single_exit_loops, set_single_exit): Declaration removed. (release_recorded_exits, record_loop_exits, rescan_loop_exit): Declare. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@120728 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/lambda-code.c | 1 - 1 file changed, 1 deletion(-) (limited to 'gcc/lambda-code.c') diff --git a/gcc/lambda-code.c b/gcc/lambda-code.c index 8972e50b3628..60e78a250720 100644 --- a/gcc/lambda-code.c +++ b/gcc/lambda-code.c @@ -2511,7 +2511,6 @@ perfect_nestify (struct loop *loop, newloop = duplicate_loop (loop, olddest->loop_father); newloop->header = headerbb; newloop->latch = latchbb; - set_single_exit (newloop, e); add_bb_to_loop (latchbb, newloop); add_bb_to_loop (bodybb, newloop); add_bb_to_loop (headerbb, newloop); -- cgit v1.2.3
