[Bug c/29868] New: Incorrect code generated for comparison

[michael dot chapman at cortus dot com]

Incorrect code is generated for the following program which I believe should
finish with "return 0" and not abort.

This was compiled with
gcc test.c
(no options).

I believe this bug is also present in gcc 4.0.3


int f(int x) __attribute__((noinline));

int f(int x)
{
    if (x < 0) 
        abort();
}

int main(void)
{ 
    int x;

    for (x = 0; x < 0x7fffffff; x += 0x10000001) 
        f(x);

    return 0;
}
