.. title:: ATOMIC_OPERATIONS_BUILTIN

.. option:: CONFIG_ATOMIC_OPERATIONS_BUILTIN

*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help
====

Use the compiler builtin functions for atomic operations. This is
the preferred method. However, support for all arches in GCC is
incomplete.

Defaults
========

No defaults. Implicitly defaults to ``n``.
