Yes, though I'm likely to treat them as lower priority for now.

Do you really need debug information

--- Comment #5 from Alexey Neyman ---
Well, that's exactly how I encountered this bug. We have some built-in
introspection in our binary and we noticed that GCC generates a lot of debug
info for local variables; the difference between -g and -g1

If t[3] was an unrelated load, then SLP does the correct thing.
E.g.
void f(double *a, double *t, double *t0, double *d)
{
double t1 = t[0] + d[0];
double t2 = t0[0] + d[1];
a[0] = t1;
a[1] = t2;
}
