I am against documenting this:
- inline is only a hint to the compiler
- the exact rules are very subtile and might differ between platforms/abi
- the behaviour might change between different compiler versions
So it is hard to document this precisely.

IMO the only proper solution is to implement delaying as compiler
intrinsics as it is done by gcc as well.
