------- Additional Comments From sabre at nondot dot org  2005-04-18 18:41 -------
Is this optimization valid?  Note that it will change the behavior of this c++
program:


----
#include <stdio.h>
static const double X = 1.0;
static struct S { S(); } s;
static const double Y = X+2.0;

S::S() {
  printf("%f\n", Y);
}
int main() {}
----

In particular, I think the C++ standard specifies that memory is zero
initialized and then ctors (within a translation unit) are run in order.  IANALL
though.
