builtins.c (unterminated_array): Pass in c_strlen_data * to c_strlen rather than just a tree *.
* builtins.c (unterminated_array): Pass in c_strlen_data * to
c_strlen rather than just a tree *.
(c_strlen): Change NONSTR argument to a c_strlen_data pointer.
Update recursive calls appropriately. If caller did not provide a
suitable data pointer, create a local one. When a non-terminated
string is discovered, bubble up information about the string via the
c_strlen_data object.
* builtins.h (c_strlen): Update prototype.
(c_strlen_data): New structure.
* gimple-fold.c (get_range_strlen): Update calls to c_strlen.
For a type 2 call, if c_strlen indicates a non-terminated string
use the length of the non-terminated string.
(gimple_fold_builtin_stpcpy): Update calls to c_strlen.
