        PR tree-optimization/89998
        * gimple-ssa-sprintf.c (try_substitute_return_value): Use lhs type
        instead of integer_type_node if possible, don't add ranges if return
        type is not compatible with int.
        * gimple-fold.c (gimple_fold_builtin_sprintf,
        gimple_fold_builtin_snprintf): Use lhs type instead of hardcoded
        integer_type_node.

        * gcc.c-torture/compile/pr89998-1.c: New test.
        * gcc.c-torture/compile/pr89998-2.c: New test.
