You want to create some minimal LLVM-IR that reproduces the issue, checking the output of the failing test case is a good start https://godbolt.org/z/aYh8WGrj3. Look at `llvm/test/CodeGen/NVPTX` for similar tests. These will run `llc` on the IR to turn it into PTX. The test should verify that the debug symbol's name matches the global string.
