That's right we do have a coverage analysis solution based on Qemu.
Execution traces generated by Qemu are analyzed by the GNATcoverage
tool to provide object, statement, decision or Modified
Condition/Decision coverage analysis.

The main interest of Qemu is to provide execution traces without
code instrumentation.

Alex, it is of course in our plans to submit patches to the upstream Qemu ;)

I give you some pointers if you want to find more on GNATcoverage (technical 
stuff :)

 * GNATcoverage is hosted on forge.open-do.org. You can checkout the
   repository with:

     $ svn checkout 
svn://scm.forge.open-do.org/scmrepos/svn/couverture/trunk/couverture

   From there, you have
     * the tool source tree in "tools"
     * a synthesis article in "publications" : 201005-erts2.pdf

 * GNATcov's documentation attached to this email
