Consider the following C++ code:
struct Foo { ~Foo() {} int i; };
struct A { Foo foo[2]; };
void foo () {
static A a;
}
We don't know the deconstructor for A is empty until we remove the empry loop
and do optimizations
on it. So this is again a job for the midde-end/tree-optimizations. We can
then mark the function as
empty and then have a pass (or really fold or something like that) remove calls
to atexit (and similar
functions) which just references empty functions. This is the correct way of
doing this.
