Using r154087, the code below never terminates with -O2 and -O3.

yang@yang-working:~$ cat small.c

{
return (si1 > (50-si2)) ? si1 : (si1 + si2);
}

my_shift(unsigned int left, int right)
{
return (right > 100) ? left : (left >> right);
}
static int func_4(unsigned int p_6)
{
for (p_6 = 1; p_6 < 3; p_6 = my_add(p_6, 1))
{
printf ("%d\n", p_6);
if (my_shift(p_6, p_6))
{
return 0;
}
}
return 0;

------- Comment #3 from rguenth at gcc dot gnu dot org 2009-11-27 14:18 -------
This is early IPA-SRA which transforms
<bb 2>:
goto <bb 9>;
<bb 3>:
p_6.0_3 = (int) p_6_1;
if (p_6.0_3 <= 100)
goto <bb 4>;
else
goto <bb 5>;
<bb 4>:
p_6_6 = p_6_1 >> p_6.0_3;
<bb 5>:
# p_6_7 = PHI <p_6_1(3), p_6_6(4)>
if (p_6_7 != 0)
goto <bb 10>;
else
goto <bb 6>;
<bb 6>:
if (p_6_1 <= 49)
goto <bb 7>;
else
goto <bb 8>;
<bb 7>:
p_6_9 = p_6_1 + 1;
<bb 8>:
# p_6_10 = PHI <p_6_1(6), p_6_9(7)>
<bb 9>:
# p_6_1 = PHI <1(2), p_6_10(8)>
if (p_6_1 <= 2)
goto <bb 3>;
else
goto <bb 10>;
to
<bb 2>:
goto <bb 9>;
<bb 3>:
p_6.0_3 = (int) p_6_2;
if (p_6.0_3 <= 100)
goto <bb 4>;
else
goto <bb 5>;
<bb 4>:
p_6_5 = p_6_2 >> p_6.0_3;
<bb 5>:
# p_6_12 = PHI <p_6_2(3), p_6_5(4)>
if (p_6_12 != 0)
goto <bb 10>;
else
goto <bb 6>;
<bb 6>:
if (p_6_12 <= 49)
goto <bb 7>;
else
goto <bb 8>;
<bb 7>:
p_6_11 = p_6_12 + 1;
<bb 8>:
# p_6_4 = PHI <p_6_12(6), p_6_11(7)>
<bb 9>:
# p_6_2 = PHI <1(2), p_6_4(8)>
if (p_6_2 <= 2)
goto <bb 3>;
else
goto <bb 10>;
see how p_6_9 = p_6_1 + 1 is changed to p_6_11 = p_6_12 + 1 forming an
endless loop - it shuld have been p_6_11 = p_6_2 + 1 instead.

I have started a bootstrap and check of the following (with a testcase
and change log and stuff...) which for some reason fixes this
(renaming introduces the mess, the code as is generated by IPA-SRA is OK):
