tree-dfa.c (dump_variable): If the variable is a pointer SSA_NAME, also dump its points-to information.
* tree-dfa.c (dump_variable): If the variable is a pointer
SSA_NAME, also dump its points-to information.
* tree-flow.h (struct ptr_info_def): Add field
is_dereferenced.
(dump_points_to_info_for): Declare.
(debug_points_to_info_for): Declare.
* tree-optimize.c (init_tree_optimization_passes): Add a
second alias analysis pass after DOM2.
Move pass_del_pta to a later spot.
* tree-ssa-alias.c (compute_points_to_and_addr_escape): Do not
create a name tags when we find a dereferenced pointer. Just
mark the pointer dereferenced.
(collect_points_to_info_for): Move code to clear points-to
information to create_name_tags.
(create_name_tags): New function.
(compute_flow_sensitive_aliasing): Call it.
(setup_pointers_and_addressables): Mark type tags for renaming
here instead of ...
(create_memory_tag): ... here.
(merge_pointed_to_info): Do not merge PT_MALLOC attributes.
(dump_points_to_info_for): Declare extern.
(debug_points_to_info_for): New function.
