[Bug middle-end/25459] [4.2 Regression] builtins.c:6283: ICE: in struct_equiv_block_eq, at struct-equiv.c:1149

------- Comment #2 from danglin at gcc dot gnu dot org  2005-12-16 21:46 -------
It seems condjump_equiv_p (info, false) returns false because
f1->dest and f2->dest are forwarder blocks:

(gdb) p/x f1->dest->flags
$6 = 0xc01
(gdb) p/x f2->dest->flags
$8 = 0xc01

  /* To simplify use of this function, return false if there are
     unneeded forwarder blocks.  These will get eliminated later
     during cleanup_cfg.  */
  if (FORWARDER_BLOCK_P (f1->dest)
      || FORWARDER_BLOCK_P (f2->dest)
      || FORWARDER_BLOCK_P (b1->dest)
      || FORWARDER_BLOCK_P (b2->dest))
    return false;
