   Means you're missing a test in SECONDARY_RELOAD_NEEDED.
   
   The P3 test is more correct.  The aligned case is handled by
   the e/W alternative.
   
Please note, this is almost surely the same bug as shown by
PR target/5628

If you fix PR target/6512 properly, you'll most likely end up
fixing PR target/5628 as well.

I am not %100 sure of this, which is why I haven't marked one
as a duplicate of the other in GNATS.  They need to both be
verified independantly once a fix is decided upon.
