Intrinsics that Generate Random Numbers of 16/32/64 Bit Wide Random Integers

There are three intrinsics returning a hardware-generated random value. These intrinsics are declared in the immintrin.h header file.

All these intrinsics are mapped to a loop around RDRAND instruction:

loop: RDRAND AX //return 16-bit random value //RDRAND EAX //return 32-bit random value //RDRAND RAX //return 64-bit random value jnc loop

• _rdrand_u16(), _rdrand_u32(), _rdrand_u64()
  Generate random numbers of 16/32/64 bit wide random integers.
