I have only followed similar hunk of code in sparc.h.
Also docs seems to mention this:
`DATA_ALIGNMENT (TYPE, BASIC-ALIGN)'
...Another is to cause
 character arrays to be word-aligned so that `strcpy' calls that
 copy constants to character arrays can be done inline.

Having string 4 byte aligned is important for current strlen expander.
8/16 byte alignmet can be possibly used once we add MMX/SIMD support.

Is there some generic code ensuring such alignments of QImode arrays
or am I missing something else?
If this code is really only wastefull, is that same case for sparc.h
so can I send patch to remove it there too?
