tree-ssa-sccvn.c (visit_reference_op_store): Do not insert struct copies into the expression table.
2008-03-03 Richard Guenther <rguenther@suse.de>
* tree-ssa-sccvn.c (visit_reference_op_store): Do not insert
struct copies into the expression table.
(simplify_unary_expression): Handle VIEW_CONVERT_EXPR.
(try_to_simplify): Likewise.
* fold-const.c (fold_unary): Fold VIEW_CONVERT_EXPR of
integral and pointer arguments which do not change the
precision to NOP_EXPRs.
* tree-ssa-loop-ivopts.c (may_be_nonaddressable_p): Adjust
VIEW_CONVERT_EXPR case.
