core::intrinsics::volatile_set_memoryExperimental

pub unsafe fn volatile_set_memory<T>(dst: *mut T, val: u8, count: uint)

Equivalent to the appropriate llvm.memset.p0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of min_align_of::<T>().

The volatile parameter parameter is set to true, so it will not be optimized out.
