I'm working on various ideas in this area; you'll find some of my 
preliminary work at:

     http://www.coyotegulch.com/acovea/index.html

That article will be revised later this week, as soon as my SPARC system 
finishes its evaluations of GCC optimizations.

I'm also rewriting an earlier article I'd written to compare the 
floating-point performance of several languages and compilers for Linux; 
the new "number crunching article" will be out before the end of the 
year, with a half-dozen benchmarks and better analysis.
