Function core::arch::aarch64::__arm_mte_create_random_tag

pub unsafe fn __arm_mte_create_random_tag<T>(
    src: *const T,
    mask: u64,
) -> *const T

🔬This is a nightly-only experimental API. (stdarch_aarch64_mte #129010)

Available on (AArch64 or target_arch="arm64ec") and target feature mte only.

Return a pointer containing a randomly generated logical address tag.

src: A pointer containing an address. mask: A mask where each of the lower 16 bits specifies logical tags which must be excluded from consideration. Zero excludes no tags.

The returned pointer contains a copy of the src address, but with a randomly generated logical tag, excluding any specified by mask.

SAFETY: The pointer provided by this intrinsic will be invalid until the memory has been appropriately tagged with __arm_mte_set_tag. If using that intrinsic on the provided pointer is itself invalid, then it will be permanently invalid and Undefined Behavior to dereference it.
