Function __sev 

pub unsafe fn __sev()

🔬This is a nightly-only experimental API. (stdarch_arm_hints #117218)

Available on ARM and (target feature v6 or AArch64 or target_arch=arm64ec) only.

Generates a SEV (send a global event) hint instruction.

This causes an event to be signaled to all processors in a multiprocessor system. It is a NOP on a uniprocessor system.
