 Yes, it's fixed, please close those bugs.

    Falk, the audit trail of this report shows that some patch

__builtin_prefetch(p, 0, 0) means "read, evict soon", so (according to
http://gcc.gnu.org/projects/prefetch.html#alpha) it ought to emit ldq,
but it emits lds. __builtin_prefetch(p, 1, 1) (rw, keep) should be
lds, but ldq is emitted.
