-- If the 'PhysicalDeviceShaderAtomicInt64Features' structure is included

-- structure passed to
-- 'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.getPhysicalDeviceFeatures2',
-- it is filled in to indicate whether each corresponding feature is
-- supported. 'PhysicalDeviceShaderAtomicInt64Features' /can/ also be used
-- in the @pNext@ chain of 'Vulkan.Core10.Device.DeviceCreateInfo' to
-- selectively enable these features.
