lack) of a tag should not determine if a value is treated as a
capability rather than an integer.

\subsection{Tagged Capabilities and Memory}

As with CHERI-RISC-V, we recommend that both memory and
registers contain tagged, 128-bit capabilities.
Since capabilities require 16 byte alignment in memory, attempts to
registers contain tagged 128-bit capabilities.
Since capabilities require 16-byte alignment in memory, attempts to
load or store capabilities at misaligned addresses should raise a
General Protection Fault with an error code of zero similar to
General Protection Fault with an error code of zero, similar to
misaligned loads and stores of SSE registers.
