re PR tree-optimization/22555 (array in struct disables salias subvars for other fields)
2006-01-05 Richard Guenther <rguenther@suse.de>
PR tree-optimization/22555
* tree-ssa-alias.c (create_overlap_variables_for): Do not give up,
if one structure field is an array.
* tree-ssa-operands.c (get_expr_operands): Continue scanning
operands even if we found a subvar, but ignore VOPs in this
case.
* tree-ssa-loop-ivopts.c (rewrite_use): Mark new vars in stmt
for renaming.
* tree-ssa-loop.c (pass_iv_optimize): Schedule TODO_update_ssa.
* gcc.dg/tree-ssa/alias-3.c: New testcase.
