Since we can now build the DeviceRTL with SPIR-V, redo the `XFAIL/UNSUPPORTED` specifications for the tests we see passing/failing on the Level Zero backend with the DeviceRTL being used. The tests marked `UNSUPPORTED` hang or sporadically fail and those are tracked in https://github.com/llvm/llvm-project/issues/182119. This change will allow us to enable CI testing with the DeviceRTL. Here are the full test results with this change applied, running only the `spirv64-intel` `check-offload` tests: ``` Total Discovered Tests: 453 Unsupported : 206 (45.47%) Passed : 141 (31.13%) Expectedly Failed: 106 (23.40%) ``` 31% is not a bad start. --------- Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
