Re: Locating a subprogram at user-specified address

["Marin David Condic" <marin.condic.auntie.spam@pacemicro.com>]

I seem to recall in Ada you could do some version of "for-use-at" for a
subprogram to get it to a specific address. Or even "for
Subprogram_Name'Address use ..." which I think is described in 13.3(10)
(Then you got to fight with the linker trying to tell it: "No. I *really*
meant to do that!") Details would be specified in Chapter 13 if so & then
you get to go looking for your compiler documentation to see what
Implementation Defined Restrictions are placed on it.
