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.
