We were taking multiple pointer arguments in the builtin.
gcc accepts a single void*.
The cast from void* to _m128i* caused the IR generation to assume
the pointer was aligned.
Instead make the builtin take a single void*, emit i8* GEPs to
adjust then cast to <2 x i64>* and perform a store with align of 1.
Key Locker provides a mechanism to encrypt and decrypt data with an AES key without having access
to the raw key value by converting AES keys into “handles”. These handles can be used to perform the
same encryption and decryption operations as the original AES keys, but they only work on the current
system and only until they are revoked. If software revokes Key Locker handles (e.g., on a reboot),
then any previous handles can no longer be used.
