This is truely ancient history, but why

Wed Sep  6 00:39:35 1989  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

        * reload1.c (reload): When setting double_reg_address_ok,
        require it to be offsettable.

There does not currently appear to be anything about the code that
is predicated on double_reg_address_ok that seems to require that
the result be offsettable.

The fact that we currently require this means that on Sparc, reloading
large offsets off of fp takes an extra instruction and register.
