--
-- == Description
--
-- This extension adds support for several new integer instructions in
-- SPIR-V for use in graphics shaders. Many of these instructions have
-- pre-existing counterparts in the Kernel environment.
--
-- The added integer functions are defined by the
-- <https://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/INTEL/SPV_INTEL_shader_integer_functions2.html SPV_INTEL_shader_integer_functions2>
-- SPIR-V extension and can be used with the
-- GL_INTEL_shader_integer_functions2 GLSL extension.
--
-- == New Structures
