Function redox::intrinsics::u64_mul_with_overflow

pub unsafe extern "rust-intrinsic" fn u64_mul_with_overflow(x: u64, y: u64) -> (u64, bool)

Unstable (core_intrinsics)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Performs checked u64 multiplication.
