Subject: [Bug middle-end/35835] Compiler fails to recognize match of local "extern" declarations
Date: Sat, 05 Apr 2008 20:59:00 -0000	[thread overview]
Message-ID: <20080405205848.28056.qmail@sourceware.org> (raw)

------- Comment #4 from rguenth at gcc dot gnu dot org  2008-04-05 20:58 -------
(works with the C frontend)

We don't share the decls of g_iValue properly, but doesn't this program
violate the ODR anyway?

void SetValue(int) (iD.2309)
{
<bb 2>:
  g_iValueD.2312 ={v} iD.2309_1(D);
  return;

}

int GetValue() ()
{
  intD.2 D.2316;

<bb 2>:
  D.2316_1 = g_iValueD.2315;
  return D.2316_1;

}

int main() ()
{
  intD.2 D.2333;
  intD.2 D.2333;
  intD.2 iValueSaveD.2320;

<bb 2>:
  iValueSaveD.2320_6 = g_iValueD.2315;
  g_iValueD.2312 ={v} 1;
  D.2333_7 = g_iValueD.2315;
  printf (&"%d\n"[0], D.2333_7);
  g_iValueD.2312 ={v} iValueSaveD.2320_6;
  return 0;

}
