-// TODO: The LLVM SPIR-V backend API has changed in
-// https://github.com/llvm/llvm-project/pull/124745 to improve the way SPIR-V
-// Backend API works with user facing options and allow for multithreading

-// contract in how options are being interpreted inside the call, and we need to
-// update this file accordingly. After this change is visible in the LLVM

-// SPIRVTranslateModule(M, Result, ErrMsg, AllowExtNames, Opts) in a style of
-// SPIRVTranslate(M, Result, ErrMsg, {"all"}, CodeGenOptLevel::Aggressive,
