From d7f2dfb67ee9c50f221d35c840d3427e8f184209 Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Tue, 20 Jan 2015 23:34:26 +0000 Subject: util/u_atomic: Use _Interlocked* intrinsics for non 64bits. The intrinsics are universally available, whereas older Windows SDKs (e.g. 7.0.7600) don't have the non-intrisic entrypoint.
