It's going wrong in iv_elimination_compare_lt which tries to exactly handle
this kind of loop:
We aim to handle the following situation:
sometype *base, *p;
int a, b, i;
i = a;
p = p_0 = b

Oops. I messed up the test case... It "works", but the actual values does not
make sense...
The following is better:
int main()
{
long pgsz = sysconf (_SC_PAGESIZE);
void *p = mmap (NULL, pgsz *

Here is a runtime testcase:
#include
#include
#include
__attribute__((noipa))
void f1 (char *p, uintptr_t i, uintptr_t n)
{
p += i;
do
{
*p = '\0';
p += 1;
i++;
}
