Backport from mainline 2019-05-06 Richard Biener <rguent...@suse.de> PR tree-optimization/90328 * tree-data-ref.h (dr_may_alias_p): Pass in the actual loop nest. * tree-data-ref.c (dr_may_alias_p): Check whether the clique is valid in the loop nest before using it. (initialize_data_dependence_relation): Adjust. * graphite-scop-detection.c (build_alias_set): Pass the SCOP enclosing loop as loop-nest to dr_may_alias_p. * gcc.dg/torture/pr90328.c: New testcase. 2019-03-08 Richard Biener <rguent...@suse.de> PR middle-end/89578 * cfgloop.h (struct loop): Add owned_clique field. * cfgloopmanip.c (copy_loop_info): Copy it. * tree-cfg.c (gimple_duplicate_bb): Do not remap owned_clique cliques. * tree-inline.c (copy_loops): Remap owned_clique. * lto-streamer-in.c (input_cfg): Stream owned_clique. * lto-streamer-out.c (output_cfg): Likewise. 2019-02-22 Richard Biener <rguent...@suse.de> PR tree-optimization/87609 * tree-cfg.c (gimple_duplicate_bb): Only remap inlined cliques. 2019-02-22 Richard Biener <rguent...@suse.de> PR middle-end/87609 * cfghooks.h (dependence_hash): New typedef. (struct copy_bb_data): New type. (cfg_hooks::duplicate_block): Adjust to take a copy_bb_data argument. (duplicate_block): Likewise. * cfghooks.c (duplicate_block): Pass down copy_bb_data. (copy_bbs): Create and pass down copy_bb_data. * cfgrtl.c (cfg_layout_duplicate_bb): Adjust. (rtl_duplicate_bb): Likewise. * tree-cfg.c (gimple_duplicate_bb): If the copy_bb_data arg is not NULL remap dependence info. * gcc.dg/torture/restrict-7.c: New testcase. 2019-02-22 Richard Biener <rguent...@suse.de> PR tree-optimization/87609 * tree-core.h (tree_base): Document special clique values. * tree-inline.c (remap_dependence_clique): Do not use the special clique value of one. (maybe_set_dependence_info): Use clique one. (clear_dependence_clique): New callback. (compute_dependence_clique): Clear clique one from all refs before assigning it (again).
