Diego Russo feda9aa73a gh-125444: Fix illegal instruction for older Arm architectures (#125574 ) On Arm v5 it is not possible to get the thread ID via c13 register hence the illegal instruction. The c13 register started to provide thread ID since Arm v6K architecture variant. Other variants of Arm v6 (T2, Z and base) don’t provide the thread ID via c13. For the sake of simplicity we group v5 and v6 together and consider that instructions for Arm v7 only.		2024-10-16 09:13:07 -04:00

The Python C API
================

The C API is divided into these sections:

1. ``Include/``: Limited API
2. ``Include/cpython/``: CPython implementation details
3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can
   change between minor releases
4. ``Include/internal/``, and any name with ``_`` prefix: The internal API

Information on changing the C API is available `in the developer guide`_
