        required: true
        type: string
        description: The architecture to build against, e.g x86_64, aarch64, s390x...

      runs_on:
        required: true
        type: string
        description: The runners to run the test on. This is a json string representing an array of labels.

        type: string
        description: The version of LLVM used to build selftest.... for llvm toolchain, this should match the one from toolchain_full, for gcc it is an arbritrary version we decide to build selftests against.
