I presume Rational's APEX compiler still uses a variant of DIANA.
Also, Concurrent built an Ada 95 compiler using the old VADS front
end, and that used a variant of DIANA.  OCS has a compiler based
on the old TeleSoft front end, and they had something approximating
DIANA.

GNAT, and the AdaMagic-based compilers (Green Hills, Aonix, etc.)
do not use DIANA in any real sense, though we of course build 
up at least some amount of abstract syntax tree and then annotate 
it during overload resolution.  

If you think of DIANA as simply an annotated abstract syntax tree for Ada,
then probably every Ada compiler uses it in some form.  If you think
of DIANA as a standard, then probably no Ada compiler uses it in
its "standard" form.  However, if you think of DIANA as a persistent, complete,
annotated abstract syntax tree used to represent the entire Ada 
program library, then APEX, Concurrent, and OCS could be considered 
DIANA users.
