+ /* We know that the range of input values covers the entire + shift space. Reduce to canonical [0,width-1]. */ + vr1.min = build_int_cst (TREE_TYPE (vr1.min), 0); + vr1.max = build_int_cst (TREE_TYPE (vr1.max), prec - 1); Wouldn't it be slightly better to just call range_includes_zero_p (&vr1) and return at this point?
