Log message:
2004-09-30 Daniel Berlin <dberlin@dberlin.org>
* tree-ssa-loop-ivopts.c (rewrite_use_address): Mark new variables
for renaming.
(tree_ssa_iv_optimize): Call rewrite_into_ssa and
rewrite_into_loop_closed_ssa.
* tree-ssa-operands.c (add_stmt_operand): We don't want to deal
with type tags. Add support for trying to find partial use/def
info.
* tree-into-ssa.c (rewrite_stmt): Call
get_intersecting_reaching_def for partial uses.
(ssa_rewrite_stmt): Ditto.
(rewrite_operand): Inlined into caller and removed.
(find_may_def_for_use): New function.
(find_must_def_for_use): Ditto.
(find_partial_def_for_use): Ditto.
* tree-ssa-structalias.c (process_unification_queue): Fix bug in
determing whether variable merging changed the solution.
Print out names being unified.
(get_constraint_for_component_ref): Update for integer_id.
(get_constraint_for): Assignments from integers now get
the INTEGER constraint.
(create_alias_vars): Mark var_readonly as address taken.
Add in integer constraint.
(alias_get_name):Call alias_get_name, not get_name, to
get ssa variable name, since alias_get_name knows
what to do with unnamed variables.
