tree-data-ref.c (analyze_array_indexes): Only estimate when estimate_only is true.
2005-09-20 Daniel Berlin <dberlin@dberlin.org>
* tree-data-ref.c (analyze_array_indexes): Only estimate when
estimate_only is true.
* tree-flow.h (ref_contains_indirect_ref): New prototype.
* tree-flow-inline.h (ref_contains_indirect_ref): Moved from
tree-ssa-structalias.c
* tree-ssa-loop-niter.c (infer_loop_bounds_from_undefined): Use
ref_contains_indirect_ref.
* tree-ssa-structalias.c (ref_contains_indirect_ref): Moved.
