Apple first used LLVM for their graphics stack, and it became more attractive to them because of the JIT stuff. Bringing Clang along is more or less an artifact of that. Maybe they weren't interested in GPLv3 since the tivoization clause prohibits them from distributing the compiler on devices which can't be flashed, but I don't think it's exactly rational. They also don't update the version of Emacs that they ship, and there you could make the argument for it since it ships with the operating system.
They wanted the freedom to make the base system read only, and I get that, but if LLVM weren't there they would be shipping GPLv3 GCC and Emacs 25.
- belorn 9y ago> tivoization clause prohibits them from distributing the compiler on devices which can't be flashed The tivoization clause has an explicit exception that allows for devices which can't be flashed. What the clause prohibits is the case when devices can only be flashed if you got the right developer password, and the publisher deny the owner of the device to have that password.
