That is roughly:
struct T
{
float __complex__ t1;
unsigned long long t2;
};
struct S
{
int s1;
struct T *s2;
};

Hi Jakub,
I looked through your patch that looks good enough although it likely
must be improved to get better vectorization for AVX-2. One general
issue is that you introduced a new pass to undo if-conversion leading
to one restriction on if-conversion that prohibited to chain the
conditions:

Hi!
This is a RFC patch which implements masked (conditional) vector
loads/stores roughly as discussed with richi (i.e. internal function
calls, added during if-conversion pass, and if not vectorized
removed after vectorization again).
The if-unconversion pass is just very basic, I guess it could
