SPIR-V Reader
This component translates SPIR-V written for Vulkan into the Tint AST.
The SPIR-V reader entry point is tint::reader::spirv::Parser, which
implements the Reader interface in tint::reader::Reader.
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.
