    # Each leg of this job builds one of them. The AVX2 and generic legs run on x86_64, the Neon leg on aarch64.

    # Coverage by other jobs:
    # - None of `avx2`, `bmi2` and `popcnt` is in the x86_64 baseline on any platform, so the AVX2 implementation
    #   is never built unless asked for explicitly - which means no other job here lints, tests or runs it.
    # - No other job builds Neon on PRs (the aarch64 test jobs only run on `main`), and no other job lints it.
    # - Generic is already linted by the "Lint" job and tested by the "Test Linux" job,
    #   so this job only runs conformance for it.
    #
    # All legs regenerate the committed conformance snapshots and fail on any diff,
    # which ensures the 3 implementations behave identically to each other.
