--- Comment #14 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
The code generated is architecturally correct. If your core is prefetching
from addresses that are not valid then this is indicative that the MMU is
incorrectly configured for your system. Prefetches will NOT be attempted from
unmapped pages, or pages that are mapped as device memory.
So you need to find out why your memory system has not been correctly set up.
There's no bug in GCC here.
