Subject: [PATCH] headers: add missing Windows ARM Interlocked intrinsics
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

On ARM, there are multiple versions of each of the intrinsics, with
acquire/relaxed/release barrier semantics.

The newly added ones are provided as inline functions here instead of builtins,
since they should only be available on certain archs (arm/aarch64).

This is necessary in order to compile C++ code for ARM in MSVC mode.

Patch by Martin Storsjö!
