Therefore, A B could only be disjoint, i.e., not aliased to each other.
We should be able to write:
if (MEM_ADDR_SPACE (mem) != MEM_ADDR_SPACE (x))
{
if (!targetm.addr_space.subset_p (MEM_ADDR_SPACE (mem), MEM_ADDR_SPACE
(x))
Thanks. I will prepare a patch.

Hi,
I am trying to implement named address space for our target.
In alias.c, I found the following piece of code several times.
/* If we have MEMs refering to different address spaces (which can
potentially overlap), we cannot easily tell from the addresses
whether the references
