Thanks for the feedback! 

The pass is applied under the following conditions (existing code in main):

```
void SPIRVPassConfig::addPreEmitPass() {
  if (SPVEnableNonSemanticDI ||
      getSPIRVTargetMachine().getTargetTriple().getVendor() == Triple::AMD) {
    addPass(createSPIRVEmitNonSemanticDIPass(&getTM<SPIRVTargetMachine>()));
  }
}
```

The tests includes `--spv-emit-nonsemantic-debug-info` so it is independent of the triple (e.g., vulkan). That is why there is no specific test for it.
