Conventional wisdom for these kinds of architectures would say that you
have no hope of generating enough ILP if you do not do speculation.
Trace scheduling + speculation seems really required to extract the
promise of EPIC architectures of this kind.
SOunds like there are a LOT of opportunities here. It is probably worth
taking a close look at what is going on in the Trimaran project.
