--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
The first major IR difference between GCC 13 and trunk happens in DOM2 where 13
would thread some jumps:
_10  : [irange] int [0, 5] NONZERO 0x5
  Threaded jump 6 --> 7 to 10
  Threaded jump 5 --> 7 to 10

While the trunk does not.
