Intel (the original authors) wrote very poor code.  In all fairness
it was supposed to be a technology demonstration, not a real compiler
for everyone to use.

The pgcc folks have fixed up the worst of the codegen bugs introduced
by Intel, but lots of work remains to make the code correct, maintainable
and generally profitable.

In some cases we're reimplementing particular optimizations from scratch
because the Intel stuff was so poorly written.

This (of course) takes time and has to be balanced with the many other
things going on with this project.

You should feel free to take some particular hunk of code from pgcc,
clean it up and submit it.  I've done it in the past, there's no reason
why other folks can't do this too.
