Support for SPV_NV_shader_invocation_reorder #2106

Hi,

We have SPIR-V modules which are translated via glslang from GLSL code that uses GL_NV_shader_invocation_reorder. We mainly use spirv-cross for reflection. For testing purposes of the extension it was sufficient to modify spirv-cross to at least successfully parse the modules with the unsupported instructions. As the performance gains from the extension were quite nice we wanted to ask whether there are already plans to support at least SPV_NV_shader_invocation_reorder.

Hi,

I came across the same issue on parsing SPIR-V modules with GL_NV_shader_invocation_reorder using SPIRV-Cross.

While the issue is being worked on, I was wondering if by any chance could you @dominikwodniokgritworld share the tweaks you made to SPIRV-Cross that enabled you to parse the modules? It would be super helpful for us.

Thanks a bunch!
