--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Mine, I wrongly ported following function:
https://github.com/gcc-mirror/gcc/blob/44511ab2471c1f88b755a5b0998fc47a8653d8c2/gcc/tree-switch-conversion.c#L1297

static bool
expand_switch_as_decision_tree_p (tree range,
                                  unsigned int uniq ATTRIBUTE_UNUSED,
                                  unsigned int count)
{
  int max_ratio;

  /* If neither casesi or tablejump is available, or flag_jump_tables
     over-ruled us, we really have no choice.  */
  if (!targetm.have_casesi () && !targetm.have_tablejump ())
    return true;
  if (!flag_jump_tables)
    return true;
#ifndef ASM_OUTPUT_ADDR_DIFF_ELT
  if (flag_pic)
    return true;
#endif
