--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a testcase which shows the removal of ABNORMAL_DISPATCHER though I am
not sure what is the best way to test if the removal makes a difference.
```
extern int vfork (void) __attribute__ ((__nothrow__ , __leaf__,
__returns_twice__));
extern int fork (void) __attribute__ ((__nothrow__ , __leaf__,
__returns_twice__));
void sink(int*) __attribute__((noipa));
void sink(int*) {}
int f(int a, int b) __attribute__((noipa));
int f(int a, int b)
{
sink(&b);
int ret = a ? vfork() : fork();
if (ret == 0) {
sink(&b);
b++;
sink(&b);
return 0;
}
if(b) __builtin_abort();
__builtin_exit(0);
}
```
