<div>
<pre>Given the following code it would be nice if there was a way to ensure that
each of the callsites to crash() remained unique so that it's possible to
distinguish which callsite is triggering a particular crash().
void crash() __attribute__((noreturn));
void f(int i) {
if (i == 5) {
crash();
}
else if (i == 7) {
crash();
}
crash();
}
Today this just gets compiled to:
f(int): # @f(int)
pushq %rax
callq crash()</pre>
