WebJun 12, 2024 · Pass the following with -V to glslangValidator (as a fragment shader): It's now my understanding that uniform blocks can't have runtime arrays (why?), and that the size is determined by the compiler. The above disassembly indicates the last member is a runtime array, so the size is not known where it could have been determined by the compiler. WebOct 13, 2024 · If the GLSL is compiled to SPIR-V (i.e. for Vulkan) then you can at least look at the SPIR-V and see what optimizations were done at that level. If the loop gets unrolled by the SPIR-V compiler, it's unlikely that it would be re-rolled by the driver compiler. However, ultimately when it's submitted to the driver it will still go through another ...
