It isn't as if Sony and Nintendo are contributing all their changes to upstream.

For example any improvements that may reveal NDA stuff from their consoles never gets upstream.

For games, most performance critical code probably does not run on the CPU but on the GPU. I believe they use pretty standard open source CPU compilers and Sony e.g. do contribute to LLVM.

I didn't said they don't contribute at all, rather "any improvements that may reveal NDA stuff from their consoles never gets upstream."

How do you think shader code gets compiled into GPGPU machine code?
