Actually I do appreciate your suggestion, though you are overestimating my

The thing is, the ultimate goal of my thesis would be, if ever, to explore
the world of Just-In-Time translation for VLIW processors. 

To me, it seems already impossible to come up with some almost-working

* for the Kaffe-JIT engine, which appears to me as a mid-size software

* which needs not be aggressively optimized, considering it will have to 
translate at run-time

* from a fairly simple instruction set as the JVM one appears to be

Thinking of writing a VLIW back end for GCC (to which none of the above
will ever apply), would no doubt make me want to kill myself right away.

By the way, what does everybody know/think of such an experiment (i.e.,
JIT for VLIW processors)? Given my total lack of knowledge on this field,
*ANY* (and I really mean *ANY*) kind of contribution could potentially
save my life and/or help me get a degree before my grandchildren do. :')

Please save my life, if you can! ;-)
Thank you for your patience.
