* tree.h (maybe_fold_offset_to_address): Declare.
* tree-ssa-ccp.c (surely_varying_stmt_p): Fix typo in last commit.
(ccp_fold): Handle pointer conversions the same as fold_stmt.
Likewise for POINTER_PLUS_EXPR.
(maybe_fold_offset_to_reference): Enable disabled code.
(maybe_fold_offset_to_address): New function.
(fold_stmt_r): Use it.
(fold_gimple_assign): Likewise.
* gimplify.c (gimplify_conversion): Use maybe_fold_offset_to_address.
(gimplify_expr): Likewise.
* gcc.dg/tree-ssa/ssa-ccp-21.c: New testcase.
* gcc.dg/tree-ssa/ssa-ccp-22.c: Likewise.
* gcc.dg/tree-ssa/ssa-ccp-23.c: Likewise.
