[PR80803 1/2] Streamline SRA access enqueuing
2017-06-13 Martin Jambor <mjambor@suse.cz>
* tree-sra.c (add_access_to_work_queue): Only enqueue accesses
that have a first_link.
(sort_and_splice_var_accesses): Do not check first_link before
enquing.
(subtree_mark_written_and_enqueue): Likewise.
(propagate_all_subaccesses): Likewise and do not stop at first
parent with a first_link.
