Looks like FreeBSD's current base build includes debugging/symbols even in
-RELEASE. I'm sure there's a reason for this.

lrwxr-xr-x 1 root wheel 5 Jun 18 09:57 /usr/local/bin/clang++ -> clang
FreeBSD and Ports installation method of CLANG differs further here

Yup, so Ports symlinks (without full path -- this should be fixed) and
FreeBSD BASE uses a hardlink.

So from what I can tell LLVM is the monster here, not Clang (which is also
of significant size, but it's 2012 so Clang isn't *that* big)
None of this seems very relevant, but here's also lines of code via
sloccount:

So GCC 4.2.1 is nearly 3 million lines of code, but CLANG+LLVM is sitting
at 1.1 million lines of code.
Are you sure CLANG is the bloated project?
