tree.h (struct tree_memory_tag): Add is_used_alone member.
2006-02-20 Daniel Berlin <dberlin@dberlin.org>
* tree.h (struct tree_memory_tag): Add is_used_alone member.
(TMT_USED_ALONE): New macro.
* tree-pass.h (PROP_tmt_usage): New property.
(TODO_update_tmt_usage): New todo.
* tree-ssa-alias.c (updating_used_alone): New variable.
(recalculate_used_alone): New function.
(compute_may_aliases): Set updating_used_alone, call
recalculate_used_alone.
* tree-sra.c (pass_sra): Note that this pass destroys
PROP_tmt_usage, and add TODO_update_tmt_usage.
* tree-ssa-forwprop.c (pass_forwprop): Ditto.
* tree-flow.h (updating_used_alone): Prototype.
(recalculate_used_alone): Ditto.
* passes.c (execute_todo): Add code to set updating_used_alone,
and call recalculate.
* tree-ssa-operands.c (add_virtual_operand): Only append bare def
for clobber if used alone, and add assert to verify used_alone
status.
