Conceptually, the concept of "target-independent RTL" seems weird to me.
But I guess you expect these to work because the backend never gets
involved trying to recognize insns or addressing modes? I think a
comment to that effect somewhere near the C code to load these tests
would be good.

That's one of the very interesting issues here. IMHO the place we wantto go with this stuff is marry it with your idea of a RTL testing backend.

Alternately we're stuck trying to get our grubby fingers into thingslike recog_for_combine.
