tree-pass.h (PROP_pta): Removed.
2007-08-14 Daniel Berlin <dberlin@dberlin.org>
* tree-pass.h (PROP_pta): Removed.
(TODO_rebuild_alias): New.
(pass_may_alias): Removed.
* tree-ssa-ccp.c (execute_fold_all_builtins): Only rebuild
aliasing if we changed something.
* tree-ssa-alias.c (compute_may_aliases): Make non-static. Update
SSA internally.
(pass_may_alias): Removed.
(create_structure_vars): Return TODO_rebuild_alias.
* tree-ssa-pre.c (do_pre): Return TODO_rebuild_alias.
* tree-sra.c (tree_sra): Only rebuild aliasing if something
changed.
(tree_sra_early): We never affect aliasing right now.
* tree-flow.h (compute_may_aliases): New prototype.
* passes.c: Remove pass_may_alias from the passes.
(execute_function_todo): Support TODO_rebuild_alias.
