* tree-ssa-strlen.c (get_addr_stridx): Add PTR argument. Assume list
is sorted by ascending list->offset. If PTR is non-NULL and there is
previous strinfo, call get_stridx_plus_constant.
(get_stridx): Pass exp as second argument to get_addr_stridx.
(addr_stridxptr): Add missing list = list->next, so that there can be
more than one entries in the list. Bump limit from 16 to 32. Ensure
the list is sorted by ascending list->offset.
(get_stridx_plus_constant): Adjust so that it can be also called with
ADDR_EXPR instead of SSA_NAME as PTR.
(handle_char_store): Pass NULL_TREE as second argument to
get_addr_stridx.
* gcc.dg/strlenopt-28.c: New test.
