--- Comment #11 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Looks to be fixed by r14-5095-g2266f7cbc78dfc for GCC 14 or an earlier one for
PR 109849.

Either way fixed for GCC 14:
  <bb 3> [local count: 1063004408]:
  # i_13 = PHI <i_10(3), 0(2)>
  # prephitmp_4 = PHI <pretmp_12(3), plaintextlen_7(2)>
  DoHuffIteration (prephitmp_4);
  i_10 = i_13 + 1;
  pretmp_12 = *a_6(D);
  if (i_10 != 10000)
    goto <bb 3>; [98.99%]
  else
    goto <bb 4>; [1.01%]
