[Bug testsuite/24263] [4.1 Regression] gcc.dg/torture/builtin-convert-1.c fails

["ebotcazou at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #4 from ebotcazou at gcc dot gnu dot org  2005-10-10 07:41 -------
Reduced testcase on SPARC/Solaris:

void test(double d1, float f1, long double ld1)
{
  extern double ceil(double);
  extern long double ceill(long double);
  extern void link_failure_outer_ceill_ceil_1(void);
  extern void link_failure_outer_ceill_ceil_2(void);

  if ((double) ceill(d1) != ceil(d1)) link_failure_outer_ceill_ceil_1();

  if ((double) ceill(f1) != ceil(f1)) link_failure_outer_ceill_ceil_2();
}

int main (void)
{
  return 0;
}


t03.gimple contains:

test (d1, f1, ld1)
{
  long double D.1278;
  long double D.1279;
  double D.1280;
  double D.1281;
  double D.1282;

  if (0)
    {
      link_failure_outer_ceill_ceil_1 ();
    }
  else
    {

    }
  D.1278 = (long double) f1;
  D.1279 = ceill (D.1278);
  D.1280 = (double) D.1279;
  D.1281 = (double) f1;
  D.1282 = ceil (D.1281);
  if (D.1280 != D.1282)
    {
      link_failure_outer_ceill_ceil_2 ();
    }
  else
    {

    }
}

Everything is folded with 4.0.x.
