It seems x86_64-apple-darwin CI has some issue?

Same?

I have no idea why the disassembler (otool) is running out of memory...

Do you want me to wait or just remove CI for osX temporary?

[Amanieu]

It might be a temporary problem with CI. Let's try again tomorrow and see if it is fixed.

Can you double-check if this is due to your changes? It seemed to be working before you added the cmp* functions.

It seems the same after I comment out cmp* functions.

Another possibility is that the cause is from some change in nightly rustc. You can test an earlier nightly by changing .github/workflows/main.yml to use a pinned nightly:

      run: |
        curl https://sh.rustup.rs | sh -s -- -y --default-toolchain nightly
        echo "$HOME/.cargo/bin" >> $GITHUB_PATH
        rustup update nightly-2021-01-23 --no-self-update
        rustup default nightly-2021-01-23
      if: matrix.os == 'macos-latest'

[Amanieu]

Sorry I missed something in main.yml. You also need to edit the line below:

    - run: |
        rustup default nightly-2021-01-23
        rustup target add ${{ matrix.target }}
      if: "!endsWith(matrix.target, 'emulated')"
