Ok, abandon that approach, no problem. After spending a week or
so tweaking my code it seems that some more pragmas to let the
programmer have more control over variable placement would be
useful, especially seeing that different targets have rather
different architectures for which the may require manual help
from the programmer to produce fast enough code. But I do
not have anything concrete yet to suggest.

That looks promising, I'll test this approach.
