To perform reflection and convert to other shader languages you can use the SPIRV-Cross API.

HLSL relies on semantics in order to effectively link together shader stages. In the SPIR-V generated by glslang, the transformation from HLSL to GLSL ends up looking like

Another thing you need to remember is when using samplers and textures in HLSL these are separable, and not directly compatible with GLSL. If you need to use this with desktop GL/GLES, you need to call `Compiler::build_combined_image_samplers` first before calling `Compiler::compile`, or you will get an exception.
```
```c++
// From main.cpp
// Builds a mapping for all combinations of images and samplers.
compiler->build_combined_image_samplers();
