| // TranslatorMetal: |
| // A GLSL-based translator that outputs shaders that fit GL_KHR_vulkan_glsl. |
| // It takes into account some considerations for Metal backend also. |
| // The shaders are then fed into glslang to spit out SPIR-V (libANGLE-side). |
| // See: https://www.khronos.org/registry/vulkan/specs/misc/GL_KHR_vulkan_glsl.txt |
| // |
| // The SPIR-V will then be translated to Metal Shading Language later in Metal backend. |
