--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which has failed since before 4.1.2:
```
static inline void set_longish(int is_long_long, void *p, long x)
{
if (is_long_long)
*(long long*)p = x;
else
*(long*)p = x;
}
static long test(long long *p, int index, int mode)
{
*p = 1;
set_longish(mode, p+index, 2);
return *p;
}
long (*volatile vtest)(long long*, int, int) = test;
#include <stdio.h>
int main(void)
{
long long x;
long result = vtest(&x, 0, 1);
printf("%lu/%llu\n", result, x);
}
```
The only difference from the original testcase is marking set_longish as static
inline. I suspect what changed between 4.7 and 4.8 for the original testcase is
inlining.
