But it also depends on what you count. Google definitely has more people working directly on LLVM itself than Apple (At Google, they almost all work for me, and I know the numbers for Apple).
If you start to include related open source projects (like clang, etc), the numbers get closer, but then you have things like all of the Android related open source stuff that gets worked on (Renderscript), etc.
In any case, i'm not sure what the goal of any corporate measuring contest would be here. We are all friendly and working on the same open source projects. It's not about what "Google is doing" or "Apple is doing" but "what is getting done in the LLVM project".
Google and Apple used to be friendly and working on the same open source project named WebKit. Looking at the precedent, it is not unreasonable to consider such things, even if everything is okay in LLVM at the moment.
