------- Comment #9 from falk at debian dot org  2006-03-04 14:35 -------
Is this really fixed? I can still reproduce it with the original testcase
(but not the reduced one) with
g++ (GCC) 4.0.3 20060212 (prerelease) (Debian 4.0.2-9)

------- Comment #10 from ted dot keller at goodrich dot com  2006-05-08 03:30 -------
Have verified bug is still an issue in 4.02 and 4.03.  Verified code in 4.03
contains the patch.  Compile still fails on mysql object sql_analyse.cc

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-08-18 18:10 -------
Confirmed, a reduced testcase:
void tree_insert();
int empty, nulls;
char found;
long long min_arg, max_arg;
static inline int compare_longlong(const long long s, const long long t) {
  return ((s < t) ? -1 : s > t ? 1 : 0);
}
int num1();
int null_value;
void add(int room_in_tree)
{
  long long  num = num1();
  if (null_value)
  {
    nulls++;
    return;
  }
  if (num == 0)
    empty++;
  if (room_in_tree)
    tree_insert();
  if (!found)
    found = 1;
  else if (num != 0)
  {
    if (compare_longlong(num, min_arg) < 0)
      min_arg = num;
    if (compare_longlong(num, max_arg) > 0)
      max_arg = num;
  }
}
----
This one fails at -O2.

This also might fail on the mainline with -O2 -fno-tree-vrp.

Also this one might fail in 3.4.x also but I have not tested it there or on the mainline yet.

So this is rtl opt bug and not a target one.  This is most likely also reproduciable on MIPS.

Reducing.
