------- Comment #4 from rguenth at gcc dot gnu dot org  2008-06-12 14:15 -------
We get different gimplification on x86_64 and ppc due to branch-cost
differences
(appearantly):

-  <D.1583>:;
-  D.1604 = i <= 125;
-  D.1605 = k <= 11;
-  D.1606 = D.1604 && D.1605;
-  if (D.1606)
+  <D.1263>:;
+  if (i > 125)
     {
-      goto <D.1582>;
+      goto <D.1264>;
     }
   else
     {
-      goto <D.1584>;
+      
     }
-  <D.1584>:;
+  if (k <= 11)
+    {
+      goto <D.1262>;
+    }
+  else
+    {
+      goto <D.1264>;
+    }
+  <D.1264>:;
