1525: Add Naga bypass to allow feeding raw SPIR-V shader data to the backend. r=kvark a=ElectronicRU **Connections** Fixes #1520 . **Description** While Naga checking is undoubtedly very useful, it currently lags behind what is possible in SPIR-V and even what is promised by WGPU (ie binding arrays). This adds an unsafe method to wgpu::Device to allow feeding raw SPIR-V data into the backend, and adds a feature flag to request a backend supporting this operation. **Testing** `texture_arrays` example is runnable now, which uncovers an additional bug in Vulkan backend - binding arrays are instead treated like sole bindings, and indices shift, too. Lots of errors from validation layer ensue. Co-authored-by: Alex S <alex0player@gmail.com> |
