Where is the documentation saying what this address space qualifier
*means*? I don't see it in either this patch or the target-independent
one. You say it exists on SPU, say how to control its size, but I don't
see anything explaining its actual semantics. Something needs to define
the target-specific semantics of the address space (possibly through
references to an external document giving compiler-independent semantics,
if this is a compiler-independent SPU extension).
