> > It does look promising, though. I hope it'll eventually surpass gcc in actually - it's matter of measurement. for example - gcc generated code is very fast, but often in expense of code size. Even -Os compiled programs are quite large. Large code=less efficient caching=SLOWER overall performance with mixed load and lots of task switching which is normal under unix. Even if this new compiler generates slightly slower but SMALLER code, it could produce overall-faster system
