/* If only one of the bounds used a MINUS_EXPR, compensate
by adding one to the other bound. */
if (parm_cst && !arg_cst)
parm_max = fold_build2_loc (input_location, PLUS_EXPR,
integer_type_node,
parm_max,
integer_one_node);
else if (arg_cst && !parm_cst)
arg_max = fold_build2_loc (input_location, PLUS_EXPR,
integer_type_node,
arg_max,
integer_one_node);
That probably should be using TREE_TYPE (parm_max) and build_int_cst (TREE_TYPE
(parm_max), 1) and similarly for arg_max...
