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:

# Dump the Tint AST after reading SPIR-V.
tint --dump-ast --parse-only a.spv

# 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.
