Yeah, me too.

I wonder if there's some gas oddity here.  The DWARF doesn't seem to be
notably weird or word-size-dependent.  I see in the old .S:

>> -#if 0 /* gas encodes it explicitly.  */
>> -        .slab128        0xffffffff00000000

>> -#endif

So hmm.

But maybe this is some kind of extension we would want to support in the
DWARF assembler.

Anyway still looking into this.
