although they are often written to disk by one process and read back in by another.
The disk version of a code object is serialized using the
[marshal](https://docs.python.org/dev/library/marshal.html) protocol.
When a `CodeObject` is created, the function `_PyCode_Quicken()` from
[`Python/specialize.c`](../Python/specialize.c) is called to initialize
the caches of all adaptive instructions. This is required because the
on-disk format is a sequence of bytes, and some of the caches need to be
initialized with 16-bit values.

Code objects are nominally immutable.

Specializing Adaptive Interpreter
=================================

Adding a specializing, adaptive interpreter to CPython will bring significant
performance improvements. These documents provide more information:

* [PEP 659: Specializing Adaptive Interpreter](https://peps.python.org/pep-0659/).
* [Adding or extending a family of adaptive instructions](adaptive.md)
