| // RemoveInactiveInterfaceVariables.h: |
| // Drop shader interface variable declarations for those that are inactive. This step needs to be |
| // done after CollectVariables. This avoids having to emulate them (e.g. atomic counters for |
| // Vulkan) or remove them in glslang wrapper (again, for Vulkan). |
| // |
| // Shouldn't be run for the GL backend, as it queries shader interface variables from GL itself, |
| // instead of relying on what was gathered during CollectVariables. |
