Hi Rogelio-

Internally I have found some interest but no official Xilinx commitment of
manpower.  That said, I'm willing and able to volunteer a bit of my time.
 I see the MBlaze port as potentially valuable for my own projects and I
found it useful as an example when porting llvm to a new architecture.  Do
you have a collection of open issues you are working through?  I'll start
by building myself a microblaze system and trying to set it up so that I
can run llvm tests.
