Reads of memory locations larger than a single machine word
are encouraged but not required to meet the same semantics
as word-sized memory locations,
observing a single allowed write <i>w</i>.
For performance reasons,
implementations may instead treat larger operations
as a set of individual machine-word-sized operations
in an unspecified order.

      A new type, <a href="/pkg/crypto/x509#OID"><code>OID</code></a>, supports ASN.1 Object Identifiers with individual
      components larger than 31 bits. A new field which uses this type, <a href="/pkg/crypto/x509#Certificate.Policies"><code>Policies</code></a>,

bytes of the string.

<p>
If the capacity of <code>s</code> is not large enough to fit the additional
values, <code>append</code> allocates a new, sufficiently large underlying
array that fits both the existing slice elements and the additional values.
Otherwise, <code>append</code> re-uses the underlying array.

Register <code>BP</code> is callee-save.
The assembler automatically inserts <code>BP</code> save/restore when frame size is larger than zero.
Using <code>BP</code> as a general purpose register is allowed,
however it can interfere with sampling-based profiling.
