------- Comment #12 from pinskia at gcc dot gnu dot org  2006-02-20 04:58 -------
Here is a testcase independent of IV-OPTs:
void abort(void);
int printf(const char *format, ...);

__attribute__((noinline))
void gen_rtx_CONST_INT(long long x) {
    if (-x > 10)
        abort();
}
__attribute__((noinline))
int alpha_expand_prologue(long frame_size)
{
    unsigned long long a;
    int probed;
    if (frame_size <= 1)  return;
    unsigned long long b = -2;
    a = -2;
    do {
        int a1 = a;
        probed = -a1;
        printf("probed = %d, frame_size = %ld\n",
               probed, frame_size);
        gen_rtx_CONST_INT (a1);
        a -= 2;
        a1 = -a;
        probed = a1;
    } while (probed < frame_size);
}

int main(void) {
    alpha_expand_prologue(10);
    return 0;
}

I tried this on 4.1.0 and could not reproduce it there, though my 4.1.0 is from
20060208.
