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.
