I meant the whole shebang.
I don't mean to distribute it. More of a massive benchmark to compare
the gcc with the best commercial compiler and see what difference it
made to applications we use all the time.
It would be interesting to do this for both 32-bit and 64-bit. Since
32-bit gcc is quite mature it could provide some insight into how to
make it better.
As for debian's free software roots, as a comparison, even OpenBSD which
rants against the GPL at any opportunity still uses gcc since there's no
other alternative; they're too small to be able to make a bsdcc.
