Most of the CI jobs log out what kind of machine they are running on. So look for a CI job named "ARM" and then look at the top of the log to see if you can find out more info. In GH actions you have to google a bit about the default runners to learn more about the CPU they have. For Travis CI there is a little blurb above the job  It appears Travis CI runs on arm64 only. However, while googling this just now, I did come across [this travis CI discussion](https://travis-ci.community/t/erlang-otp-21-1-4-is-missing-but-only-for-arm-64/6438/7) which suggests that Linux supports emulating arm32 on arm64 systems (using setarch). It sounds like we could use that to create a 32-bit ARM build in Travis if we wanted to. -- This is an automated message from the Apache Git Service.
