re PR tree-optimization/69615 (0 to limit signed range checks don't always use unsigned compare)
PR tree-optimization/69615
* fold-const.c (merge_ranges): If range1 is - [x, x] and x is the
maximum or minimum of the type, try to merge it also as if
range1 is + [-, x - 1] or + [x + 1, -].
* gcc.dg/pr69615.c: New test.
