--- Comment #17 from Georg-Johann Lay <gjl at gcc dot gnu.org> ---
Giving up on this.  A working solution as patch series is here, so anyone can
pick it up.

Note that it only can be done for artificial data -- or you have to make sure
that the data is not accessed by inline asm by different means (and of course,
no pointers must escape, and a respective hook must not be called from within
the C++ front-end).
