------- Comment #3 from pinskia at gcc dot gnu dot org 2007-02-27 07:01 ------- Before we would produce: i = &a + 12B; i = i - 4B; D.1616 = &a - 4B; if (i > D.1616)
Now we produce: i = &a + 12B; D.1620 = i > &a; i = i - 4B; if (D.1620) Which is better because we can actually fold it down to return 0. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29715
