tree-ssa-ccp.c (ccp_fold): Also read from constant values and fold constant aggregate refs.
2008-03-15 Richard Guenther <rguenther@suse.de>
* tree-ssa-ccp.c (ccp_fold): Also read from constant values
and fold constant aggregate refs.
(fold_const_aggregate_ref): Handle string constants
and constructors in ARRAY_REFs. Handle INDIRECT_REF.
(evaluate_stmt): Simplify now that ccp_fold folds constant
aggregate refs.
* gcc.dg/tree-ssa/ssa-ccp-16.c: New testcase.
