PentiumGCC - http://www.goof.com/pcg/ fixes some problems there,
but it introduces more bugs), since it assumes that you have many

From what I understand of Merced, compiler technology is going to be the
problem. It's probably not unreasonable to expect large performance
increases as the intelligence of compilers (especially the "free"
compilers like gcc and egcs) catches up
I imagine you could significantly speed up the code by keeping
much of the
data in register. REG-REG operations take a lot less time than
a REG-MEM
operation. Should be delicious.

As for the compilers, remember that RISC type architecture is nothing
really
new...and EPIC type stuff has been around a while. There are already
compilers for other systems that contain much of the brains to do the
optimizations already...they just need to get those smarts moved over to
