--- Comment #3 from Jeffrey A. Law <law at gcc dot gnu.org> ---
This seems to have been fixed for gcc-17.  In the .combine dump it gets
simplified here:

Trying 30, 39, 38 -> 40:
   30: r157:DI=0x880
   39: r166:DI=0x1
   38: r165:DI=r155:DI&r157:DI
      REG_DEAD r155:DI
      REG_DEAD r157:DI
   40: pc={(r165:DI==r166:DI)?L45:pc}
      REG_DEAD r166:DI
      REG_DEAD r165:DI
      REG_BR_PROB 365072225
Failed to match this instruction:
(set (pc)
    (pc))
