SPIR-V samples for WGSL

These samples are extracted from the unit tests for the SPIR-V reader in Tint. See the SPIR-V reader source code.

The original sources are distributed under the Apache 2.0 LICENSE.

I don't plan to take contributions. Instead, contribute tests to upstream projects such as Tint. You can file a Tint bug at https://crbug.com/tint.

There are over 1000 .spvasm files which can be assembled into SPIR-V binary modules that should be convertable into valid WGSL.

Example:

tint --format wgsl spvasm/SpvUnaryLogicalTest_LogicalNot_Scalar.spvasm

produces the following output:

fn main_1() {
  let x_1 : bool = !(true);
  return;
}

[[stage(fragment)]]
fn main() {
  main_1();
}

The examples work in Tint.

The SPIR-V is valid for SPIR-V 1.0, but some examples use:

• SPV_KHR_storage_buffer_storage_class
• StorageBuffer storage class (without extension)
• SPV_KHR_non_semantic_info
• SPV_KHR_vulkan_memory_model

Support notes

The SPIR-V reader in Tint lags other support in Tint.

For example:

• read-only storage textures have been removed from WGSL and WebGPU, but the SPIR-V reader still generates them. Sampled textures should be used instead.
