Hints to compiler that affects how code should be emitted or optimized.



Informs the compiler that this point in the code is not reachable, enabling further optimizations.

A function that is opaque to the optimizer, to allow benchmarks to pretend to use outputs to assist in avoiding dead-code elimination.

spin_loop Experimental

Signals the processor that it is entering a busy-wait spin-loop.
