Reduced testcase:
Even though there is an overflow which the C front-end says the code was in an
if (0) block so it should
not matter about that as it is only undefined then but

Simple code which shows we now have a missed optimization:
static const double a = 1.0;
static const double b = a+1.0;
double c()
{
return b;
}
See PR 21089.

I believe the optimization necessitates the variable's declaration be changed
(either explicitly, or by implication):
static const double b = a+1.0; = const double b = a+1.0;

A recent change on CVS HEAD breaks this:

No, the code is invalid, as Y has not been interjected yet. This is a
progression and not a regression.

Missed tail call optimization when local address could escape but not on the
condition:
void f(void);
void f1(int *);
void g(int i, int j)
{
if (j)
return f();
return f1(i);
}
This might be a reduced testcase from fold_binary to fold_build2 where we have
this issue, but I have
