cfgloop.h (loop_iterator::~loop_iterator): Remove.
2019-11-21 Richard Biener <rguenther@suse.de>
* cfgloop.h (loop_iterator::~loop_iterator): Remove.
(loop_iterator::to_visit): Use an auto_vec with internal storage.
(loop_iterator::loop_iterator): Adjust.
* cfganal.c (compute_dominance_frontiers_1): Fold into...
(compute_dominance_frontiers): ... this. Hoist invariant
get_immediate_dominator call.
(compute_idf): Use a work-set instead of a work-list for more
optimal iteration order and duplicate avoidance.
* tree-into-ssa.c (mark_phi_for_rewrite): Avoid re-allocating
the vector all the time, instead pre-allocate the vector only
once.
(delete_update_ssa): Simplify.
* vec.h (va_heap::release): Disable -Wfree-nonheap-object around it.
