## 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 `SPV_INTEL_shader_integer_functions2` SPIR-V extension and can be used with the `GL_INTEL_shader_integer_functions2` GLSL extension.
