It should work. Or at least is it the intention.

To know more about UVMs, have a look at:

The MVM is a discrete event simulator, working hand in hand with an
instrumenting compiler and a "real-time aware" graphical frontend for
gdb. In order to use it, you first have to configure and install it.

You will have to compile your applications for this simulation
environment using "gcic" the instrumenting compiler, and run them
through "xenoscope", the gdb graphical frontend.

For examples of programs using the native skin, which can be compiled
for MVM, see the directory:
skins/native/demos

For the MVM full documentation, see:
sim/doc/mvm-manual.txt
