--
-- == Description
--
-- This extension allows a shader to perform 16-bit floating-point atomic
-- operations on buffer and workgroup memory as well as floating-point
-- atomic minimum and maximum operations on buffer, workgroup, and image
-- memory. It advertises the SPIR-V @AtomicFloat16AddEXT@ capability which
-- allows atomic add operations on 16-bit floating-point numbers and the
-- SPIR-V @AtomicFloat16MinMaxEXT@, @AtomicFloat32MinMaxEXT@ and
-- @AtomicFloat64MinMaxEXT@ capabilities which allow atomic minimum and
-- maximum operations on floating-point numbers. The supported operations
-- include @OpAtomicFAddEXT@, @OpAtomicFMinEXT@ and @OpAtomicFMaxEXT@.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceShaderAtomicFloat2FeaturesEXT'
--
-- == New Enum Constants
--
-- -   'EXT_SHADER_ATOMIC_FLOAT_2_EXTENSION_NAME'
--
-- -   'EXT_SHADER_ATOMIC_FLOAT_2_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_ATOMIC_FLOAT_2_FEATURES_EXT'
--
-- == Issues
--
-- 1) Should this extension add support for 16-bit image atomics?
--
-- __RESOLVED__: No. While Vulkan supports creating storage images with
-- 'Vulkan.Core10.Enums.Format.FORMAT_R16_SFLOAT' and doing load and store
-- on them, the data in the shader has a 32-bit representation. Vulkan
-- currently has no facility for even basic reading or writing such images
-- using 16-bit float values in the shader. Adding such functionality would
-- be required before 16-bit image atomics would make sense and is outside
-- the scope of this extension.
