??? One can specify that the integer memory ops should be used instead,
|
||
and treat fp values as just a series of bits. One might even bubble
|
||
that notion up into the description language. However, that departs from
|
||
gcc. One could cross over from gcc's notion and a "series of bits" notion
|
||
between there and here, and thus still not require these routines. However,
|
||
that's a complication of its own (not that having these fns isn't).
|

But for now, we do things this way. */
