``class Architecture`` is the parent class for all CPU architectures. Subclasses of Architecture implement assembly,
disassembly, IL lifting, and patching.
``class Architecture`` has a metaclass with the additional methods ``register``, and supports
iteration::
>>> #List the architectures
>>> list(Architecture)
[<arch: aarch64>, <arch: armv7>, <arch: thumb2>, <arch: armv7eb>, <arch: thumb2eb>, <arch: mipsel32>, <arch: mips32>, <arch: ppc>, <arch: ppc64>, <arch: ppc_le>, <arch: ppc64_le>, <arch: x86_16>, <arch: x86>, <arch: x86_64>]
>>> #Register a new Architecture
>>> class MyArch(Architecture):
... name = "MyArch"
...
>>> MyArch.register()
>>> list(Architecture)
[<arch: aarch64>, <arch: armv7>, <arch: thumb2>, <arch: armv7eb>, <arch: thumb2eb>, <arch: mipsel32>, <arch: mips32>, <arch: ppc>, <arch: ppc64>, <arch: ppc_le>, <arch: ppc64_le>, <arch: x86_16>, <arch: x86>, <arch: x86_64>, <arch: MyArch>]
>>>
For the purposes of this documentation the variable ``arch`` will be used in the following context ::
>>> from binaryninja import *
>>> arch = Architecture['x86']
.. note:: The `max_instr_length` property of an architecture is not necessarily representative of the maximum instruction size of the associated CPU architecture. Rather, it represents the maximum size of a potential instruction that the architecture plugin can handle. So for example, the value for x86 is 16 despite the lagest valid instruction being only 15 bytes long, and the value for mips32 is currently 8 because multiple instrutions are decoded looking for delay slots so they can be reordered.
