one can read about the possible substitution of GCC by LLVM (among
other candidates). Under the assumption that LLVM is selected, would
this mean that FreeBSD will somehow integrate the

I think the idea is to get away from gcc with its evil GPL3 license as the
very good move. i wasn't aware that usable GCC replacement exist, as it
was probably the only reason to keep communist licenced programs with
master FreeBSD sources.

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

Please don't read too much into my remark, as I don't like to engage in
license ideology debates. I like GPL, BSD, and all the zillions of other
i do use GPL programs too without any problems - because there is
no BSD licenced equivalent (most often), or BSD
I'm a big supporter of small, efficient binaries. In fact, I'll often put
-Os in my /etc/make.conf CFLAGS setting. This only rarely improves raw
speed over more agressive optimization flags, however. I use it primarily
it do improves speed on DSP-like code that do repetitively the same on
