One big issue with DirectXShaderCompiler was test coverage: DXIL and SPIR-V backends had their own tests. When a bug was found in one, the other wasn't always checked. This lead to unequal support of HLSL for both backends. We'd like to avoid those issues here, hence the test-sharing. By default, all the tests in this folder are marked as requiring DirectX. But as SPIR-V support grows, each test drop this requirement, and check the SPIR-V behavior. I would have preferred to mark new tests as XFAIL for SPIR-V by default, so we could differentiate real unsupported tests (as SPIR-V has no equivalent), from newly added tests. But the way LIT is built, I don't think this is possible. --------- Signed-off-by: Nathan Gauër <brioche@google.com>
