cfg.h (struct control_flow_graph): Add edge_flags_allocated and bb_flags_allocated members.
2018-08-24 Richard Biener <rguenther@suse.de>
* cfg.h (struct control_flow_graph): Add edge_flags_allocated and
bb_flags_allocated members.
(auto_flag): New RAII class for allocating flags.
(auto_edge_flag): New RAII class for allocating edge flags.
(auto_bb_flag): New RAII class for allocating bb flags.
* cfgloop.c (verify_loop_structure): Allocate temporary edge
flag dynamically.
* cfganal.c (dfs_enumerate_from): Remove use of visited sbitmap
in favor of temporarily allocated BB flag.
* hsa-brig.c: Re-order includes.
* hsa-dump.c: Likewise.
* hsa-regalloc.c: Likewise.
* print-rtl.c: Likewise.
* profile-count.c: Likewise.
