-- == Description
--
-- This extension allows a shader to contain floating-point atomic
-- operations on buffer, workgroup, and image memory. It also advertises
-- the SPIR-V @AtomicFloat32AddEXT@ and @AtomicFloat64AddEXT@ capabilities
-- that allows atomic addition on floating-points numbers. The supported
-- operations include @OpAtomicFAddEXT@, @OpAtomicExchange@, @OpAtomicLoad@
-- and @OpAtomicStore@.
