[gentoo-amd64] How much value does llvm provide for a low-use laptop?

[Mark Knecht]

My wife is not looking for high performance and the machine uses
nvidia-drivers. (If it matters)

As best I can tell using equery the only package that seems to want it is
mesa and there's a llvm flag implying maybe I can turn it off. I'm updating
her machine and it's been grinding away on this one package for over 2
hours now. If it's not really required then I'd like to write it out of my
future.

Thanks in advance,
Mark
