| # SPIR-V Reader | |
| This component translates SPIR-V written for Vulkan into the Tint AST. | |
| The SPIR-V reader entry point is `tint::spirv::reader::Read()`, which | |
| performs the translation of SPIR-V to a `tint::Program`. | |
| It's usable from the Tint command line: | |
| # Translate SPIR-V into WGSL. | |
| tint --format wgsl a.spv | |
| ## Supported dialects | |
| The SPIR-V module must pass validation for the Vulkan 1.1 environment in SPIRV-Tools. | |
| In particular, SPIR-V 1.4 and later are not supported. | |
| For example, the equivalent of the following must pass: | |
| spirv-val --target-env vulkan1.1 a.spv | |
| Additionally, the reader imposes additional constraints based on: | |
| * The features supported by WGSL. Some Vulkan features might not be supportable because | |
| WebGPU must be portable to other graphics APIs. | |
| * Limitations of the reader itself. These might be relaxed in the future with extra | |
| engineering work. | |
