We miss an opportunity to remove the bounds checking code in the following case (this shows up a
huge amount in libjava and other code):
class t
{
void f(int a[])
{
for(int i=0;i<a.length;i++)
a[i] = 0;
}
}

The tree level looks like after optimization:
t.f(int[]) (this, a)
{
int i;
int D.385;
unsigned int i.3;
int D.376;
<bb 0>:
D.376 = a->length;
if (D.376 <= 0) goto <L8>; else goto <L17>;
<L17>:;
i = 0;
<L1>:;
i.3 = (unsigned int) i;
if ((unsigned int) D.376 > i.3) goto <L5>; else goto <L2>;
<L2>:;
D.385 = _Jv_ThrowBadArrayIndex (i);
<L5>:;
*(&a->data[0] + (int *) i.3 * 4B) = 0;
;
i = (int) (i.3 + 1);
D.376 = a->length;
if (i >= D.376) goto <L8>; else goto <L1>;
<L8>:;
return;
}

Note that even though (i_30 >= D.1909_5), VRP does not clean this up.
The exception stays there until DOM1.

tree-chrec.h.
(cfg_loops): New local variable.
(compare_values): Forward declare.

Decay to VR_VARYING ranges that take all possible values in
the type domain.
(compare_values): Do some symbolic comparisons.
(value_inside_range): Move earlier in the file.

(extract_range_from_assert): If the ASSERT_EXPR conditional
and the variable have intersecting ranges, use the
intersection to derive a narrower range.

(extract_range_from_binary_expr): Re-arrange to always call
set_value_range to set the newly computed range.
(extract_range_from_unary_expr): Likewise.
Do not special case ABS_EXPR.
If a type cast operation changes to a type of different size,
set the resulting range to VR_VARYING.
If the new range has the limits swapped around, set the result
to VR_VARYING.

Fix calls to compare_values to always check for specific
return values.

Fix. http://gcc.gnu.org/ml/gcc-patches/2005-02/msg01074.html.
The patch allows VRP to eliminate 42% more conditionals on cc1-i-files and 173%
more conditionals on DLV. But produces little difference in MICO and TRAMP3D.

No, but for 4.1, reopening as there is no 4.1 right now.

Suspending as fixed and moving the target milestone to 4.1.0 so we know to retest it when tcb gets

Now the problem is that we don't remove the extra load of a->length because of aliasing.
