re PR middle-end/27793 (num_ssa_names inconsistent or immediate use iterator wrong)
2006-06-07 Andrew MacLeod <amacleod@redhat.com>
PR middle-end/27793
* tree-dfa.c (referenced_vars_dup_list): New. List of duplicate
referenced_variables with matching DECL_UID's.
(find_referenced_vars): Make sure duplicate list is empty to start.
(referenced_var_p): Remove.
(referenced_var_check_and_insert): Renamed from referenced_var_insert.
Check if var is in the list, and add if needed. Update the duplicate
list if a different var is in the list with the same DECL_UID.
(add_referenced_var): Call routine to check and insert.
* tree-ssa.c (delete_tree_ssa): Clear var_ann's on duplicates.
* tree-flow.h (referenced_vars_dup_list): External declaration.
