+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
+http://htmlpreview.github.io/?https://github.com/KhronosGroup/SPIRV-Registry/blob/master/extensions/INTEL/SPV_INTEL_shader_integer_functions2.html[+SPV_INTEL_shader_integer_functions+]
+SPIR-V extension and can be used with the GL_INTEL_shader_integer_functions2 GLSL extension.
