## Description

This extension allows GLSL shaders written to the `GL_KHR_vulkan_glsl` extension specification to be used instead of SPIR-V. The implementation will automatically detect whether the shader is SPIR-V or GLSL, and compile it appropriately.

## Deprecation

Functionality in this extension is outside of the scope of Vulkan and is better served by a compiler library such as glslang. No new implementations will support this extension, so applications should not use it.

## New Enum Constants

- `VK_NV_GLSL_SHADER_EXTENSION_NAME`

- `VK_NV_GLSL_SHADER_SPEC_VERSION`

- Extending VkResult:

  - `VK_ERROR_INVALID_SHADER_NV`

## Examples

Example 1

Passing in GLSL code

        char const vss[] =
            "#version 450 core\n"
            "layout(location = 0) in vec2 aVertex;\n"
            "layout(location = 1) in vec4 aColor;\n"
            "out vec4 vColor;\n"
            "void main()\n"
            "{\n"
            "    vColor = aColor;\n"
            "    gl_Position = vec4(aVertex, 0, 1);\n"
            "}\n"
        ;
        VkShaderModuleCreateInfo vertexShaderInfo = { VK_STRUCTURE_TYPE_SHADER_MODULE_CREATE_INFO };
        vertexShaderInfo.codeSize = sizeof vss;
        vertexShaderInfo.pCode = vss;
        VkShaderModule vertexShader;
        vkCreateShaderModule(device, &vertexShaderInfo, 0, &vertexShader);
